Future of Engineering

What's the common factor amongst these films - Spiderman, Hulk & Superman? You'd immediately say 'Super hero'. But what makes them super on screen? No, it's not their flying, diving and crashing skills that create a big impression. It's their special effects.

Production houses can afford to spend millions on special effects. But it is not possible for an amateur trying his/her first stint at photography and editing.

Unwrap Mosaics a prototype software from Microsoft offers a simple and easy solution. A video is simply a sequential collection of frames or still images. If special effects have to be applied to an object, each and every frame where the object appears has to be edited separately. This is a laborious and time consuming task.


Unwrap Mosaics was developed by Rav-Acha, Andrew Fitzgibbon, Pushmeet Kohli and Carsten Rother. It virtually strips the skin from a selected object in a video, producing a 2D surface that can be easily edited using photo-editing software.

Rav-Acha and his co-workers have successfully tested their software on a range of videos. "There are professional tools that can do these kind of edits but it's an incredibly skilled procedure," says Fitzgibbon. "We believe that with this procedure anyone should be able to edit video."

Using this software, the editor can sit back and relax after making changes to a single frame. The software takes care of applying the changes to all the frames. For instance, if you add a hat and boots to your cat video in frame one, the changes appear till the end of the video.

Now everybody has the chance to create a home edition of Hancock, the super guy of the 21st century.

Tool converts written text to an electronically generated voice.



Visually impaired people surf the net with the help of special screen-reading software which they install in their desktops. But they cannot use the net on the go.

A new software, called WebAnywhere, tackles this problem effectively. The tool developed at the University of Washington turns screen-reading into an Internet service that reads aloud Web text on any computer. It will run on any machine that has a sound card.

Under Richard Ladner's supervision, Jeffrey Bigham, a UW doctoral student in computer science and engineering was able to create this tool that has become the first accessibility tool to be hosted on the Web.

Usually free screen readers have to be downloaded and installed before you can use it. But in some places like public libraries or museums there could be download restrictions. Webanywhere doesn't have to be downloaded. It processes the text on an external server and then sends the audio file to play in the user's Web browser.

Because there is no installation involved, there is no need for technical support. Everytime you visit the site you get the latest version.

You can access WebAnywhere here.

Researchers at Purdue have put their minds together to create tiny refrigerators. This tiny little thing isn't going to store your foodstuff. Instead it's getting inside a computer to keep it cool.

Conventional methods:

In most computers, fans circulate air through finned devices called heat sinks attached to computer chips. And they do a pretty good job of keeping electronic components cool. But when a computer generates too much heat, liquid cooling, also known as water cooling has been looked upon as a good solution.

Indian American Suresh Garimella, of Purdue University takes it one step further. He believes that tiny fridges will be placed in future computers to keep it cool.

How it works:
The researchers developed an analytical model for designing tiny compressors that pump refrigerants using penny-size diaphragms and validated the model with experimental data. The elastic membranes are made of ultra-thin sheets of a plastic called polyimide and coated with an electrically conducting metallic layer. The metal layer allows the diaphragm to be moved back and forth to produce a pumping action using electrical charges, or "electrostatic diaphragm compression."

Why miniature refrigeration?
Trends suggest that future computer chips will generate 10 times more heat than today's microprocessors. So it makes sense to find ways to increase the efficiency of the machine.

Refrigeration is doubly efficient because it can cool the chips below the surrounding temperature which is not possible with conventional methods.

Hope this cool computer finds its way to the shelves soon.

“This is an unobtrusive monitoring system that will increase the safety of seniors and improve their ability to live independently,” Tyrer said.

Harry Tyrer, a University of Missouri electrical and computer engineering professor alongwith MU nursing Associate Professor Myra A. Aud is exploring the use of sensor technology in construction.

This fantastic duo has come up with the creation of the smart carpet that promises to help the elderly people who have trouble while walking.

They have introduced a new type of sensor that can be printed on thin, flexible sheets using organic ink. Organic ink sensors are flexible and inexpensive. This would be placed on the sensor sheet that is layered between the room's carpet and the carpet pad.

Once this is done, it will be easy to spot the movement of the person. This technology would be very helpful in hospitals, care taking institutions and homes of senior citizens. A caregiver can easily track the movement of the patients and can be immediately alerted if someone falls.

It can also provide additional info about the changes in gait or behaviors that can indicate a fall. This is not possible with the current sensor technologies. Because current floor sensor systems depend on vibration readings to monitor a person's activity. But it is not dependable and easily prone to misinterpretation.

"Some parts of the Web have so much extraneous material that it can be distracting, and for the nonverbal child, there might not be an ability to negotiate that information," adds Stephen Sheinkopf, an autism researcher at Brown University.

ZAC is the first web browser developed specifically for children with autism, and autism spectrum disorders such as Asperger syndrome, pervasive developmental disorders (PDD), and PDD-NOS. It has a high chance of increasing a child's ability to do things independently.

Zackary, the 6-year-old grandson of John LeSieur was diagnosed with autism in 2005. Being in the software business John LeSieur wanted his grandson to play games and use the computer. Unfortunately Zachary found it hard to navigate inside the world wide web.

That's when Grandpa LeSieur decided to create a special browser for the little kid.He has named it the Zac Browser For Autistic Children and is making it available to anyone for free.

The Zac Browser greatly simplifies the experience of using a computer. It seals off most Web sites from view, to block violent, sexual or otherwise adult-themed material. Instead it presents a hand-picked slate of choices from free, public Web sites, with an emphasis on educational games, music, videos and visually entertaining images, like a virtual aquarium.

Thanks to grandpa's gift, Zachary listens to music and plays puzzles - things he always liked before but hadn't been able to explore online.

The Zac Browser can be downloaded or run directly from: http://www.zacbrowser.com

An atomic force microscope image of a simple circuit with 17 memristors lined up in a row.

Researchers at HP Labs have solved a decades-old mystery by proving the existence of a fourth basic element in integrated circuits that could make it possible to develop computers that turn on and off like an electric light.

The memristor — short for memory resistor - could make it possible to develop far more energy-efficient computing systems with memories that retain information even after the power is off, so there's no wait for the system to boot up after turning the computer on. It may even be possible to create systems with some of the pattern-matching abilities of the human brain.

This invention, as is obvious, has huge potential in electronics. Well, simply put, if this works out according to plan, no RAM will be needed in our computers! In addition, this could result in analog computers that process information the way the human brain does.

This is what Wikipedia has to say:

"
Memristors ("memory resistors") are a class of passive ideal two-terminal circuit elements that maintain a functional relationship between the time integrals of current and voltage. This results in resistance varying according to the device's memristance function. The definition of the memristor is based solely on fundamental circuit variables, similarly to the resistor, capacitor, and inductor. Unlike those more familiar elements, memristors may be described by any of a variety of time-varying functions. As a result, memristors do not belong to linear circuit models including time. A time-invariant memristor is simply a conventional resistor.

The Hewlett Packard memristor, based on a thin film of titanium dioxide, appears to be practical and ideal in its initial incarnation. However, as of yet, none have been reported outside HP. Being much simpler than currently popular MOSFET transistor switches and also able to implement one bit of memory in a single device, memristors may enable nanoscale computer technology. (Its inventor) Chua also speculates that they may be useful in the construction of artificial neural networks.

Memristors can implement memory on the principle that direct current applied in the component can adjust its apparent resistance. This resistance may then be observed using alternating current.
"

While using memristors, the memory will be a part of the circuitry rather than a separate module; this will save valuable space. It can make possible for computers to power up instantly, cell phones will go much longer without a charge, and no information will ever be lost in case of power failures or battery death.

Scientists can now think about fabricating a new type of non-volatile random access memory (RAM) – or memory chips that don't forget what power state they were in when a computer is shut off. The big problem with DRAM today is that when you turn the power off on your PC, the DRAM forgets what was there. So the next time you turn the power on you've got to sit there and wait while all that you need to run your computer is loaded into the DRAM from the hard disk. With non-volatile RAM which could be possible using memristors, that process would be instantaneous and your PC would be in the same state as when you turned it off.

In addition to a better, non-volatile RAM, its inventors think memristors could also speed up neural computing. While a lot of researchers are currently trying to write a computer code that simulates brain function on a standard machine, they have to use huge machines with enormous processing power to simulate only tiny portions of the brain.

The memristor team feels these folks can now take a different approach: "Instead of writing a computer program to simulate a brain or simulate some brain function, we're actually looking to build some hardware based upon memristors that emulates brain-like functions".

The person originally behind this interesting invention, Leon Chua, had the idea of the memristor almost 37 years back!

What if you could just sneak $1 out of the wallet of 50,000 different people? They probably won’t notice. If they discover the $1 missing, they probably won’t care, or may even assume they just lost it or mis-counted.

Now, what if you could sneak $1 from 50,000 different people while sitting at your laptop in the local coffee shop? What if you never have to physically confront a single person, nor risk physical harm in any way? What if you could perpetrate a virtual crime, cyberpickpocketing? How about if your cyberpickpocketing could net $50,000 today? That definitely sounds like a more solid business plan than the “Pickpocketing Across America” approach cited above. That is the allure of cybercrime, says this interesting post

Got me thinking about cybercrime in general, not just micro-commerce cyber crime. How is cybercrime going to evolve in future? What will be its various dimensions? And what are we doing about it? I have provided the various interesting resources I found during my research for answers to the above questions.

This interesting post @ ThinkQuest ( http://library.thinkquest.org/04oct/00460/future.html ) was certainly thought-provoking. It discusses how the rate of malware penetration in wireless and PCs is increasing. It also notes how malware are becoming more intelligent by the day. It concludes that "Trends suggest that criminals will become more insidious. Large-scale and damaging acts such as Dos attacks will become less popular as they are easy to detect and thwart with better security systems. Instead, newer and more indirect methods of crime like phishing and Trojans will become much more popular".

In this report Predicting the future of cybercrime and security, Alan Paller of SANS Institute provides details on predictions by twenty respected leaders in cyber focusing on the top 10 security developments for 2007. They narrowed 40 probable computer security developments down to 10 that have the highest probability of happening and will, if they happen, have substantial impact on large numbers of people. The developments predicted are in the following domains: 1. Laptop encryption, 2. PDA smart phones, 3.Targeted cyber attacks, 4. Cell phone worms, 5. Voice over IP (VoIP) systems, 6. Spyware, 7. Security vulnerabilities, 8. Rootkits, 9. Legislation governing the protection of customer information and 10. Network access control (NAC). In summary, the report says that attacker sophistication seems to be ahead of defensive tools. But by making the attackers' job harder and harder and by increasing the length of gaol sentences for cybercrime and improving international police co-operation and skill levels, we can continue to keep up with the attackers and, over time, begin to turn the tide.

In this brief interview titled Protecting the future from cyber crime, Platypus Magazine spoke with Federal Agent Nigel Phair about his new book and the impact of high-tech crime as he sees it, and the challenges which lay ahead in controlling cyber crime. Some of the questions posed in the interview are: "What are the challenges which lie ahead in policing high tech crime?", "Can policing keep up with the evolution of cyber crime – or is this an unwinnable war?", "Does a cyber criminal fit a typical profile?", & "Who do you see as being the most vulnerable to high tech crime?". Interesting perspectives in the answers.

According to Dan Hubard, a cybercime expert, cybercrime is all about costs and benefits, and criminals are no different from legitimate businesses in this respect. "The old criminals are learning from the new ones how to launder stolen credit cards, and they are learning how little risk they face of being caught," he said. The old criminal gangs have a lot of money that they can plough into cybercrime, which is potentially much more profitable that traditional forms of crime and is less risky.

The U.S. military has hinted that it will expand its cyber crime to cyber warfare in the near future, according to this article. Lt. Gen. Robert J. Elder Jr., who heads the Air Force's cyber operations command told the press that the military was currently developing ways to launch virtual attacks on enemies. The general even reckoned that if cyber squaddies could use the Net to scramble an enemy's communications system, they might even be able to do away with heavy handed conventional weapons like bombs.

First it was SAAS and now it it is CAAS - Crimeware as a Service. Criminals invest in crimeware-as-a-service, says this interesting article from Computerworld UK. 'Crimeware as a service', where criminals use online cybercrime services instead of running their own servers and software, is the latest development in internet crime. Hmmm

The Internet Crime Complaint Center posted their latest statistics on cybercrime recently, based on nearly 207,000 complaints people filed in 2007. Since 2006 losses to cybercrime had jumped over 20%, although complaints fell slightly. Over a third of the complaints were about auction fraud, the center said, and a quarter were about non-delivery of goods. Credit/debit card fraud, check fraud, identity theft and Nigerian letter fraud were also represented.

"Years ago, we saw cybercrime as a speciality," says a Dutch expert. "Now we have added cybercrime in every form of police training, so we are raising the level of the entire Dutch police force. There's no crime anymore where there are no digital components built in."

I guess the last statement kind of sums it up. Cybercrime is not a specialty crime any longer. It is a part of most crimes happening today. Not the most pleasant of news!

So, you either believe that IT is undergoing yet another upheaval, or you don't.
You either buy into Nicholas Carr's core premise (as found in "The Big Switch"), or you don't.

But if you do buy into these ideas, there's another implication to consider.
There will likely be very little medium-sized IT in the future. Just the very big, and the very small.

Over time, IT is done much more efficiently at uber-scale. Much like power generation shifted from small-scale to large-scale at the beginning of the 20th century, we're seeing the same thing applied to IT at the dawn of the 21st century.

New research commisioned by Visa Europe and unveiled at the World Retail Congress in Barcelona shows that, contrary to suggestions, online channels can complement bricks and mortar stores.

With internet sales expected to account for almost 20% of turnover by 2012-15, and websites becoming increasingly transactional rather than informational, there is also likely to be a rise in the application of technology within the retailer community. As a result there would be a rise in automated self scanning, product tracking for inventory using RFID (Radio-Frequency Identification) and targeted promotions delivered directly to consumers while they shopped. In addition they were likely to have access to PC/web based facilities in store giving immediate access to product and customer reviews

If you think the touchscreen on Apple's iPhone is cool, imagine a device that actually sees, reflects and responds to your fingers touching the back of the device. A prototype of that capability was among many that Microsoft Research showed off at TechFest , Microsoft's annual display of its research projects. LucidTouch isn't very practical in its current form. It's a large handheld computer with a small video camera attached to an arm about 30cm long on the back of the device. But the technology that enables it could easily change now that the concept is proven, said Patrick Baudisch, a researcher at Microsoft.

The current setup includes a touch sensor layer on the back of the device. That senses when a user's fingers are touching it. The camera attached behind it sends an image of the fingers to the device, where the image is overlaid lightly, like a shadow, on the screen. Moving your fingers on the back of the device, you can choose an item on the map. With LucidTouch, a user could touch an area on the wristband of the watch instead to make choices on the watch face.

IBM is working on its latest "racetrack" memory, which it promises will bring a 100 fold increase in density -- by storing data in long magnetised nanowires rather than disks. Don't make computers seek out data, make the data move to where it can be used. That's one way to describe "racetrack" memory, which IBM argues could one day lead to memory that could hold 100 times more data than flash memory does today and cost 100 times less

In racetrack memory, information is stored in the domain walls, or boundaries, between magnetic regions on a wire. The domain walls are then shuttled up or down the wire via electrical pulses toward another component that can interpret whether the domain wall represents a "1" or a "0".

In flash memory and hard drives, data lives in a discrete location and a computer (or hard drive head) finds it. Shuttling the bits on a wire opens up the possibility for making 3D memory, and hence more dense memory, because wires could be stacked on top of each other. The time it takes to record or retrieve data could also be reduced. Racetrack chips, potentially, could additionally last far longer because they have no moving parts, unlike hard drives, and won't get progressively worn out by successive read-erase cycles like flash memory.

In the next two to four years, IBM hopes to create a complete, working prototype of a racetrack chip with an integrated device that can read the data shuttling across the wire

India often undermines the innovative prowess of the domestic players and have so far been looking for technological innovations from the West, rues Ajai Chowdhry, Chairman & CEO, HCL Infosystems. He is glad, however, that with the launch of innovative products like Tata Nano, the common perception is slowly but surely changing.

To the league of recent innovation closer home, Ajai likes to add the HCL MiLeap range of Leaptops. “With its ultra small form factor, offering mobile computing at an unbeaten price of Rs 13,990, MiLeap is set to create a new product segment in our country,” he mentions confidently, during the course of an e-mail interaction with Business Line.

“Other innovations in the past include our products like the sub-10K PC which broke the price barriers in the market and set the industry trend of affordable computing among the desktop category,” says Ajai. “The computer that runs on a car battery, the four in one computer, the point of sale product and the ‘Data Centre’ in a box were all developed at our R&D centre.” This article contains excerpts from the interview.

On March 20, the US Patent & Trademark Office published a new patent application of Apple’s that reveals they’re working on a next generation 3D Holographic-like display system. In one application, Apple’s display system would automatically authenticate a user, greet them and provide a customized desktop for just that user. Something along the lines of how new computer car systems will adjust the seat and controls for a particular driver. The Holographic-like displays are based on a projection system and in many cases the impression given is that these systems would apply to applications as diverse as video conferencing, scientific modeling, entertainment and perhaps even forensics. Think of the TV show “Bones” and their use of a device called holographic “angelator.” One of the unique aspects of this invention is that users won’t be hassled with 3D glasses or headgear of any kind.

Modern three-dimensional (”3D”) display technologies are increasingly popular and practical not only in computer graphics, but in other diverse environments and technologies as well. Growing examples include medical diagnostics, flight simulation, air traffic control, battlefield simulation, weather diagnostics, entertainment, advertising, education, animation, virtual reality, robotics, biomechanical studies, scientific visualization, and so forth.

Apple’s patent illustrates the nuts and bolts of their proposed 3D display system according to one embodiment of the invention. You’ll note that the system includes a host CPU, an operating system (”OS”), a 3D/stereoscopic rendering engine, a graphics card, and other components (not shown) as will be conventionally understood. The 3D/stereoscopic rendering engine renders 3D images (e.g., stereoscopic or pseudo-holographic) as further described herein below, and may be implemented in firmware, software, or hardware, according to the particular implementation at hand.

We've all asked ourselves that irritating question: "Where on earth did I leave my car keys?"

A team of Japanese scientists claims to have come up with the answer, and the secretive artificial intelligence project code-named Smart Goggle does not stop at elusive keys!

With Yasuo Kuniyoshi's invention balanced on your nose, you will lose nothing. Simply tell the glasses what you are looking for and it will play into your eye a video of the last few seconds you saw that item.

Well, it's not magic, right? So how does it work?

Behind the goggles is an advanced object-recognition software and a computer that can learn the identity of new objects within seconds. So this is what you do, as a user: to start with, you wander around your house for about an hour "telling" the goggles the name of everything you see around you, as you fix your eyes on that object. So you essentially pronounce "coat hanger" when you are in front of the coat hanger and the word "kitchen sink" when you are in front of the kitchen sink - you get the idea. Once this process is over, the software using object recognition tech, stores the image of the object against the word you pronounced. Every time after that you move around your house, as and when that product is sighted by the goggles (though perhaps not perceived by you), its location is stored. And when you are at a loss one fine day as to where you left that product, all you need to do is to say the product name, and voila, the goggles tell you where you (rather, the goggles!) last saw it.

Sounds like a very sophisticated solution to a simple problem, but admit it, this simple problem can be at times most vexing, so who knows, the Smart Goggles could be a big hit!

John Campbell, after a year of experimentation, 10 to 15 old computers and more than $500 in cash, Campbell's best invention, an arcade machine-sized freezer brimming with gooey liquids, ice and techno-pieces, was ready to boot for the first time. After this period of experimentation, Campbell's "liquid computer" came alive, the first of its kind.

Campbell fully intends to spark a computer-technology revolution with the items in his freezer. Since the first time the liquid computer worked, Campbell, along with his team of five specialists in areas such as materials, programming, chemistry and engineering, have reduced the size of the original liquid computer to that of a modern desktop. The technology, which Campbell says is 70 to 90 percent unpatented, achieves a mild form of super fluidity, a frictionless flow of liquid at extremely low temperatures, to increase the resistance of computer wires, which allows for a greater flow of electricity and higher efficiency.

"There hasn't been a fundamental change in computer technology since 1982, and since then, it has just been putting more things in smaller places," Campbell said. "I think it's about time for something completely new that is so practical you can't ignore it."

The new dean of the Faculty of Arts and Sciences (FAS) at Harvard University—an institution with a deep commitment to freedom of expression—is the inventor of a software technique designed to keep unauthorized people from reading electronic documents.

Liquid Machines, a Waltham, MA, startup founded in 2001 by Harvard’s Michael Smith is founded on a clever idea pioneered by Smith that the company calls “application injection.” The technology takes over word-processing programs, e-mail software, and the like, automatically encrypting digital documents and then decrypting them for authorized users without requiring users to exchange passwords or cryptographic keys or attend to other special chores.

“Tens of billions of e-mails are sent each day,” says Ruffolo. “Just ask yourself, how many of those have proprietary information, and how many of those are sent erroneously? You look at that, and you start to say, ‘I need something to control the flow of information that’s leaving my company.’ The most dangerous breach is the one that you’re not aware of.”

Application injection is essentially the process by which Liquid Machines’ main product, called Liquid Machines Document Control, fuses itself into and takes control of virtually any other program that can play or display digital content—such as Microsoft Word and Adobe Acrobat. The “injection” happens at the moment the display program is loaded

The most powerful computer known is the brain, and now scientists have designed a machine just a few molecules large that mimics how the brain works.

So far the device can simultaneously carry out 16 times more operations than a normal computer transistor. Researchers suggest the invention might eventually prove able to perform roughly 1,000 times more operations than a transistor.

This machine could not only serve as the foundation of a powerful computer, but also serve as the controlling element of complex gadgets such as microscopic doctors or factories, scientists added.

The device is made of a compound known as duroquinone. This molecule resembles a hexagonal plate with four cones linked to it, "like a small car," explained researcher Anirban Bandyopadhyay, an artificial intelligence and molecular electronics scientist at the National Institute for Materials Science at Tsukuba in Japan.

Computers, long used as tools to design and manipulate three-dimensional objects, may soon provide people with a way to sense the texture of those objects or feel how they fit together, thanks to a haptic, or touch-based, interface developed at Carnegie Mellon University. Unlike most other haptic interfaces that rely on motors and mechanical linkages to provide some sense of touch or force feedback, the device developed by Ralph Hollis, research professor in Carnegie Mellon’s Robotics Institute, uses magnetic levitation and a single moving part to give users a highly realistic experience. Users can perceive textures, feel hard contacts and notice even slight changes in position while using an interface that responds rapidly to movements.

The system eliminates the bulky links, cables and general mechanical complexity of other haptic devices on the market today in favor of a single lightweight moving part that floats on magnetic fields.

A user moves the handle much like a computer mouse, but in three dimensions with six degrees of freedom — up/down, side to side, back/forth, yaw, pitch and roll. Optical sensors measure the position and orientation of the flotor, and this information is used to control the position and orientation of a virtual object on the computer display

The reign of the silicon chip is over, according to physicists who predict that the conventional silicon chip has no longer than four years left to run. Meeting at the Institute of Physics’ Condensed Matter and Material Physics conference this week, researchers speculate that the silicon chip will be unable to sustain the same pace of increase in computing power and speed as it has in previous years

Just as Gordon Moore predicted in 2005, physical limitations of the miniaturised electronic devices of today will eventually lead to silicon chips that are saturated with transistors and incapable of holding any more digital information. Scientists are now investigating alternative components that may pave the way to faster, more powerful computers of the future and potentially extend Moore’s Law of technological advancement

One team of researchers at the Leeds University in the UK have proposed to replace silicon chips with carbon nanotubes. In a development that is expected to bring carbon nanotubes one step closer to commercial use, the Leeds University researchers have developed a technique of growing nanotubes on a perforated ceramic grid. The technique allows the research team to determine the electrical properties of individual nanotubes, after which the tubes are accurately positioned on a surface using a tweezer-like device

By linking the electric current in a loop to a quantum superposition state, superconductors may act as quantum bits, or qubits, in quantum computing. Qubits are able to exist in multiple states at any one time, which massively increases the amount of information that can be encoded in a quantum computer’s memory.

T.J. Rodgers, an outspoken free markets advocate and founder of Cypress Semiconductor says many have tried, but none have succeeded in creating other Silicon Valleys around the world. The region's unique combination of talent, money and unconventional thinkers, he says, simply can't be replicated. Rogers has been a major force in the Valley for nearly 40 years and has lived through every tech trend.

About 20 years ago, Rodgers took a page from his venture capital friends and started an incubator for semiconductor start-ups at Cypress. All told, the San Jose, Calif.-based company has invested $600 million in nine start-ups that have a market cap of $3.6 billion today - most of which is from solar cell maker SunPower, which went public in 2005. Rodgers talked with Forbes.com about the history of innovation in the Valley and innovation in silicon chips - the technology that started it all and gave the region its name.

To the question "Will China or any other place ever rival the Valley?", he answers, "Not in my lifetime. You have to have multiple technologies interacting with each other, free market capital that's willing to take large risks, business acumen to start a company and, most of all, a culture that supports and respects those values." You can find more on the interview here.

This certainly got me thinking. Rogers is not the first to spell out the unique advantages present in the silicon valley ecosystem, but the innovation coming out of that environment is so huge that it is worth revisiting the concept.

For sure, there are other regions in the world where a lot of high-tech is happening. Well, within the US, there are other regions that do a lot of tech innovation stuff as well. Illinois, Washington...some of the brightest tech concepts have come from these regions. Israel is one country that has produced exceptional tech innovation per capita. Parts of Europe, Finland for instance

I wouldn't include China in this list, I doubt they have ever been known for innovative tech. Perhaps India, but even that country has had few breakthrough innovations coming out, most of what it has produced is a large "software factory", certainly not an innovation factory.

So well, there is competition - at least some - for Silicon Valley, but how strong is the competition? Let's analyze.

The other regions in the US - These probably have similar market situations to that of Silicon Valley, but what could be missing from these is the culture that supports companies that take risks in unknown technologies - some of which require a willing suspension of disbelief. At the end of the day, even the smartest bunch of bankers do not make a single visionary tech investor.

Parts of Europe - these have potential in terms of potential and talent, but I again doubt if they have the culture that supports such groundbreaking innovation. Finland and a couple of other Scandinavian countries appear to be one some of the few countries that has produced such genius (Linux, Nokia, Skype, Jaiku. These are markets that are close to London ( and hence money), and they are also part of the European Union - these two aspects give them some distinct market advantages. On balance, there appears to be potential in this region.

Israel - it has the genius and they have certainly proven themselves many times over when it comes to tech innovation, but their being so far away from any other tech cluster and their small size make it difficult for them to be a serious threat to silicon valley.

Japan - Japan has not done well when it comes to disruptive , especially software and Internet related (which was the last great Internet product / concept that came out of Japan? Hmm...I am really scratching my head!). Plus, anyway their corporate culture is miles away from the type of culture that can nurture groundbreaking innovation. I wouldn't even consider them to be in the contention.

China and India - have more been technology factories, not laboratories by any stretch of imagination. Their sizes certainly makes one thing a bit longer before dismissing them, but they are way, way behind in the race. There is really no chance of them catching up with Silicon Valley in the next decade or two.

So where does that leave the scorecard? This is my ranking, based on all the above aspects:

Silicon Valley - 10 / 10
Scandinavia - 4 / 10
Israel - 3 / 10
Japan - 0 / 10
India / China - Let me not bother ranking these

That's some competition for Silicon Valley, wouldn't you agree.

Pirated microchips account for billions of dollars in annual losses to chipmakers. But a series of novel techniques developed at Rice University over the past year could stop pirates by allowing chip designers to lock and remotely activate chips with a unique ID tag

When a chip is locked with the new technology, only the patent-holder can decipher the key and activate the chip -- meaning knockoffs and stolen chips are worthless.

This month, Koushanfar and colleagues at the University of Michigan, Igor Markov and Jarrod Roy, unveiled a new form of the technology called “EPIC: Ending Piracy of Integrated Circuits" at the IEEE Design Automation and Test Conference in Europe.

Hardware makers have tried a number of approaches to safeguard designers' IP. But safeguarding individual ICs – and not IPs – is the unique aspect and contribution of Koushanfar’s work.

Computers may soon provide people with a way to sense the texture of objects or feel how they fit together, thanks to a haptic, or touch-based, interface developed at Carnegie Mellon University. The device developed by Ralph Hollis, research professor in Carnegie Mellon's Robotics Institute, uses magnetic levitation and a single moving part to give users a highly realistic experience. Users can perceive textures, feel hard contacts and notice even slight changes in position while using an interface that responds rapidly to movements.

The field of haptic research and development is expanding rapidly. Carnegie Mellon's research opens new possibilities by joining the world of haptic feedback with a comfortable magnetic levitation interface.

The system eliminates the bulky links, cables and general mechanical complexity of other haptic devices on the market today in favor of a single lightweight moving part that floats on magnetic fields.

In the future your face, and not hands, will do the work. Breakthroughs in computerized facial expression and voice recognition technology are heralding a new era in communications that requires virtually no physical exertion whatsoever – not the click of a mouse or the tap-tap-tap of a keyboard. It'll save space on your desk and could put an end the ache of carpal tunnel syndrome. It will be a godsend for people with severe arthritis in their hands and arms. Like the voice command technology used in cars to keep drivers' hands on the steering wheel, much of this computerized communication is coming down the pipe in bits and pieces.

Technology for computerized facial recognition is ten times more accurate now than it was four years ago, and the best of the systems outperform humans, the National Institute of Standards said almost a year back.

Its facial-recognition test has compared vendor systems on in their ability to recognize high-resolution still images and three-dimensional facial images, under both controlled and uncontrolled illumination. According to the NIST report issued in late March 2007, the facial recognition systems it tested in the trials showed an “order of magnitude,” or tenfold, improvement over comparable tests conducted four years ago.

A new facial-recognition algorithm created by researchers at the University of California at Berkeley and University of Illinois at Urbana-Champaign is able to recognize faces with 90-95 percent accuracy, even if the eyes, nose and mouth are obscured

Reaffirming these trends, a number of consumer products today are coming out with visual recognition capabilities. Some of the new Toshiba laptops such as Portege M800, Satellite M300 and A300 recognize your face. A bunch of researchers from Tel Aviv University have even managed to successfully 'teach' a computer how to spot an attractive woman. Wow!

Voice recognition is making rapid strides too

Yahoo has released a new application that allows users to search the web with voice commands. The feature is part of oneSearch version 2, due to be released during the summer. However, the company is offering BlackBerry users an early peek of the voice recognition technology at m.yahoo.com/voice.

Mac users now have the option to use voice recognition tech too, thanks to MacSpeech Dictate.

Products such as Nuance voicemail to text make the transformation of voice and text messages easy and at the same time lets one access, sort, forward and archive their messages. The voicemail transformed texts are compatible with all standard message media. So that's voice recognition transforming the way you read email!

It's early days yet for facial and voice recognition systems. Sure, there are still lots of promises that face recognition and voice recognition systems are yet to deliver on, but the current status is, some elements of these technologies are poised for greatness even when still in the prototype stage, and some are already available to consumers and work just fine.

You can look forward to a future that involves a lot less using your fingers to type and a lot more using your face to talk and communicate.

Here are some more interesting resources for computerized facial & voice recognition, for those whose curiosity is never satisfied easily!

In an ultrahigh-vacuum chamber at Swinburne University of Technology, a million ultracold rubidium-87 atoms hover just beneath the surface of a silicon chip coated with a thin magneto-optical film.

Tailored to create a shaped, perpendicular magnetic field, the magnetic film confines and shepherds the rubidium atoms on the chip, in much the same way as electrons are guided along conducting wires on an electronic microchip.

Cooled to a temperature of a few billionths of a degree Kelvin, just above absolute zero (minus 273˚C), and confined by a magnetic microtrap on the chip, the ultracold atoms fall into the lowest energy state of the trap and no longer jostle for room – they exhibit almost no random thermal motion.

The atoms condense to a state where they behave as a single super-atom of rubidium-87 and exhibit coherent, wave-like properties – rather like the coherent light from a laser. For several seconds, the chip holds the atoms in an exotic, fifth state of matter called a Bose–Einstein condensate.

If all this sounds ‘sci-fi’ it’s because in many ways it is. Bose–Einstein condensate is a new frontier whose boundaries have yet to be measured, but are more than likely to take humankind to new realms of technological and industrial capability.

Just as the first lasers mystified scientists as to their possible applications, so too now with Bose–Einstein condensate. In theory, they could at the very least be the basis for quantum computing – that is, computers able to use atoms to store data and complete in seconds computations that would take today’s most powerful supercomputers years.

Accenture exec says eight trends will change the data center – storage and all. Every five years, Kishore Swaminathan, chief scientist at global services outfit Accenture, confers with colleagues on the key factors driving IT for the next three to five years. These are the trends the firm will use to guide product and service investments, marketing, training, and other activities.
This year's findings have a number of implications for storage managers -- and the higher up you are, the more you'll be affected.

"Broadly, the conclusions are that the role of the CIO is about to change fairly dramatically," says Swaminathan.

Indeed, Accenture predicts a shakeup in IT that could profoundly change the nature of jobs in and around the data center. To understand what's predicted requires a look at the eight top trends Accenture has defined. Following, in no particular order, are the factors Swaminathan says will shape IT for the next five years, along with the impact they'll have on the CIO's job and the implications for storage networking:

Trend No. 1: Cloud computing
Trend No. 2: Shadow IT. The capabilities of open-source software, along with widgets and mashup solutions, are allowing corporate employees to set up applications without IT at an unprecedented rate.
Trend No. 3: Enterprise Intelligence
Trend No. 4: Continuous user connectivity
Trend No. 5: Social computing
Trend No. 6: User-generated content
Trend No. 7: Software development revised
Trend No. 8: Green computing

A lot of these trends point to futures that may not happen for many companies. But in larger enterprises, Swaminathan thinks they will have an impact on CIOs in a number of ways

Where is storage in all this? "Hardware is going more and more toward scale, to the point where it won't be economical for anyone to run a small data center," Swaminathan says. Ecosystem cloud suppliers will buy storage in bulk and squeeze storage manufacturers for better deals.

It makes sense for big storage suppliers to start their own ecosystem clouds, compete with applications like document management.

“Security experts warn that as supply chains become more global and more opaque, no one can be sure what parts are going into the computers that run, well, everything from air traffic control towers to banks to weapon systems,” Popular Mechanics says. In an article, “The Manchurian Chip,” Glenn Derene and Joe Pappalardo outline in detail the possible dangers.

“Individuals, companies and federal agencies could all be at risk from foreign governments or criminal enterprises,” they write. “A computer chip built with a subtle error might allow an identity-theft ring to hack past the encryption used to connect customers with their banks.”
In addition, they say, flash memory hidden in a corporation’s printers could capture an image of every document produced and send it on to people who should not have it.

A European consortium has drafted a roadmap for the future of sound and music computing (SMC), which provides the core technologies for the burgeoning electronic music industry

Drawing on inspiration from hard sciences like physics and engineering, social sciences like psychology and musicology, and the creative arts, digital musical instruments, CDs, MP3s and other innovative ICTs owe a great debt to SMC.

According to Nicola Bernardini, who coordinated the two-year IST-funded project, SMC research is behind the music industry as we know it today. With the appropriate guidance - the ambition of the S2S² roadmap - Europe could be in a position to secure leadership in this field.

Commercial music today is largely produced using computing and technology as a 'surrogate' for the real thing because using real instruments, learning to play them – or paying someone else to play them – can be expensive and time-consuming.

But this is a rather narrow view of the sector, said Bernardini. "With our roadmap, we wanted to show what SMC can be (and has already been) in research terms. [Music is] not only an economic lever but good for social cohesion."

Five key challenges have been identified:

1. Design better sound objects and environments (improving the sounds produced by objects present in our environment to enhance their emotional character).
2. Understand, model and improve human interaction with sound and music.
3. Train multidisciplinary researchers in a multicultural society.
4. Improve knowledge transfer.
5. Address social concerns.

A team of physicists and engineers has demonstrated exquisite control of single particles of light -- photons -- on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer.

Dr Jeremy O'Brien, his PhD student Alberto Politi, and their colleagues at Bristol University have demonstrated the world's smallest optical controlled-NOT gate -- the building block of a quantum computer.

The team were able to fabricate their controlled-NOT gate from silica wave-guides on a silicon chip, resulting in a miniaturised device and high-performance operation.

"This is a crucial step towards a future optical quantum computer, as well as other quantum technologies based on photons," said Dr O'Brien

The silicon chip, which has supplied several decades’ worth of remarkable increases in computing power and speed, looks unlikely to be capable of sustaining this pace for more than another decade – in fact, in a plenary talk at the conference, Suman Datta of Pennsylvania State University, USA, gives the conventional silicon chip no longer than four years left to run.

As silicon computer circuitry gets ever smaller in the quest to pack more components into smaller areas on a chip, eventually the miniaturized electronic devices are undermined by fundamental physical limits. They start to become leaky, making them incapable of holding onto digital information. So if the steady increases in computing capability that we have come to take for granted are to continue, some new technology will have to take over from silicon.

Replacing the chip with carbon nanotubes

Carbon nanotubes, discovered in 1991, are tubes of pure carbon just a few nanometres wide – about the width of a typical protein molecule, and tens of thousands of times thinner than a human hair. Because they conduct electricity, they have been proposed as ready-made molecular-scale wires for making electronic circuitry.

Some nanotubes behave as semiconductors, like silicon; others carry electric currents like metal wires. Already, fundamental elements of computer circuits such as transistors have been made from individual carbon nanotubes.

In the scientific campaign to build intelligent machines, soccer is the new chess. Just as Carnegie Mellon University produced the prototype computer that eventually checkmated World Champion Garry Kasparov in 1997, it now leads efforts to create robots that will defeat the world's best 11-man squad on grass by 2050.

There's serious science behind this. If robots are going to fight forest fires or build skyscrapers, they first have to learn how to work as a team -- on their own, under pressure, when every second counts.

CMU's small robot squad, four-time world champions, astounds Eric Horvitz, president of the Association for the Advancement of Artificial Intelligence.

Scientists claim to have developed a music storage format that uses the absolute least amount of data needed to reproduce a piece of music.

By virtually modelling the interactions between a clarinet and clarinet player, researchers have digitally reproduced a 20-second instrumental solo in a file nearly 1,000 times smaller than a regular MP3 file.

"This is essentially a human-scale system of reproducing music," said Mark Bocko, professor of electrical and computer engineering at the University of Rochester and co-creator of the technology.

In developing the format, researchers built a computer model of the clarinet based on measurements of every aspect of the instrument that affects its sound: from the back-pressure in the mouthpiece for every different fingering, to the way sound radiates from the instrument.

The team then created a virtual clarinet player by modeling the interactions between the musician and instrument, including the fingerings, the force of breath, and the pressure of the player's lips to determine how they would affect the response of the virtual clarinet.

Then it was a matter of letting the computer "listen" to a real clarinet performance to infer and record the various actions required to create a specific sound. The original sound is then reproduced by feeding the record of the player's actions back into the computer model.

While they have not yet achieved a flawless reproduction of an original performance on the clarinet, the researchers expect their finish line to be not far away.

"Maybe the future of music recording lies in reproducing performers and not recording them," Bocko said.

Remote hi-tech outposts where computers are housed in 'server farms' and powered by wind and solar energy could slash the carbon footprint of business-related IT, a Cambridge computer guru believes.

Professor Andy Hopper, who heads up the University of Cambridge Computer Laboratory, said it was the belief "that we can help save the planet and provide a sustainable future for generations to come" that was driving exciting new research at the Computer Laboratory. He said: "Computing power can be moved around the world and can be done anywhere in the world where the energy is available."

Professor Hopper said that the energy needed to power computers was extremely portable and therefore could be created from solar or wind energy in one location and transferred to computers in another, faraway place.

Since it was easier and more efficient to transfer information than to transfer power across great distances, Professor Hopper suggests moving server centres closer to the source of the energy. He is championing 'server farms' located in remote areas with ample wind or solar energy, connecting to computers around the country.

The purrfect companion? Computers designed to bring man and machine closer than ever

By 2020 the terms "interface" and "user" will be obsolete as computers merge ever closer with humans.

It is one prediction in a Microsoft-backed report drawn from the discussions of 45 academics from the fields of computing, science, sociology and psychology.

It predicts fundamental changes in the field of so-called Human-Computer Interaction (HCI).

By 2020 humans will increasingly interrogate machines, the report said.

In turn computers will be able to anticipate what we want from them, which will require new rules about our relationship with machines.

The report, entitled Being Human: Human-Computer Interaction in the year 2020, looks at how the development of technologies over the next decade can better reflect human values.

Communication devices for the home that Microsoft is working on include Epigraph, an interface that allows family members to "post" pictures and messages to each other via their mobile phones.

Also, the keyboard, mouse and monitor will increasingly be replaced by more intuitive forms of interaction and display, including tablet computers, speech recognition systems and fingertip-operated surfaces.

Scientists and engineers are racing to develop ways to use light instead of electricity to avoid traffic jams inside computers.

Today’s fastest computers employ miles of tiny copper wires to connect multiple data processors packed on silicon chips. Each little "brain" - in effect, a miniature adding machine - must exchange information with hundreds or thousands of partners on the same or connecting chips.

"The weakest link in the overall capability of the computer is the ability to move information from chip to chip," said John Stroman, a computer design strategist at Intel Corp., the big computer-chip maker based in Santa Clara, Calif. "Moving information around is the biggest limitation on the performance of computers, and it becomes a greater limitation as CPUs become faster."

Computer scientists think that the solution may be photons, the tiny packets of energy that make up a beam of light. Photons aren’t the same as electrons, the fundamental particles of electricity.

The science of photons is known as "nanophotonics," since it deals with infinitesimally small elements at the nanoscale. A nanometer is 1 billionth of a meter; a nanogram is 1 billionth of a gram.

It will be several years before photons can do much of the work of electrons, but the pace of research is accelerating.

"Within the next five years, practical methods to move information around using light will exist," said an expert.

There was a time, some years back, when a few distinguished folks in the scientist community thought that computers might indeed start thinking on their own. Things have gone relatively quiet on this front since then, though even today you hear the occasional noises. But, while artificial intelligence is an oxymoron - or at best an overhyped promise - in many scientists' opinion, there is little doubt that today's computers and computing infrastructure can perform things that would have been considered pure magic even a few decades back

Recent attempts at making computers emulate human beings in thought, such as the Blue Brain project, have also met with reasonable success. To some around the world, this growth in computing power and sophistication is a cause of concern - "will they take over human beings?". To some others, it is a cause of celebration - "sciece has won after all

But relatively few of them are asking the question "If computers are superior to our brains in some aspects, can our brains be used for far more enriching work?" Once we recall the fact that our brain is not just one whole, but that there are compartments in it that do different things (differently), then our perspective is likely to change. To make things simpler and more logical, it is better to consider the brain's two main compartments - the right hemisphere and the left hemisphere.

Although popularized in the 1980s by the artist Betty Edwards in her book “Drawing on the Right Side of the Brain,” the right-brain-left-brain dichotomy originated with the research of the American biologist Roger W. Sperry in the 1960s. Through studying “split brain” animals and human patients, whose brain hemispheres had been disconnected, he found that each side of the brain plays its own role in cognition.

With its 100 billion cells forging 1 quadrillion connections, the human brain is breathtakingly complex. In the last 10 years however, thanks in part to advances in functional magnetic resonance imaging, researchers have begun to identify more precisely how the two sides divide responsibilities.

The left side, home of the human language center, is the outspoken logical, linear half of the equation. Our left hemisphere thinks linearly and methodically. It's that calculating intelligence that reminds me when I have to do my laundry. But perhaps most important, it's that little voice that says to me, "I am. I am."

The right side, home to spatial perception and nonverbal concepts, is the nonlinear, high-concept source of the imagination and of pleasure. Our right hemisphere is all about right here right now. It thinks in pictures and it learns kinesthetically through the movement of our bodies. It explores what this present moment looks like, what this present moment smells like and tastes like, feels and sounds like

The two hemispheres constantly send signals back and forth through a bundle of 200 million to 300 million nerve fibers to help balance learning, analysis and communication throughout the brain.

(Here is an easy-to-understand comparison of the right and left brain roles & functions).

Humans have benefitted from both these roles over their entire evolution, though individuals have always had preferential consumption of each - some were more left-brained (your typical computer-geek, for instance), and some were more right-brained (that creative painter down your alley). Some, like Da Vinci (or Einstein), had used both hemispheres well

Using the right side of my brain I can take my dreams, I can connect them to my reality, and I can make my dreams come true. But my right needs the left - to make my dreams become a reality, I need to process my thoughts, and work on them logically. Thus, the right and left brains have been working in a symbiotic fashion for long. In the 20th century however, the left counterpart started getting a lot more attention and came to be much more valued than the left.

The key ability of our right brain, the ability to help us see from an artist’s perspective, and the alternative way of thinking that this engenders have traditionally been marginalized in the business and corporate world of the 20th century. Until recently, the abilities that led to success in school, work, and business were characteristic of the left hemisphere. They were the sorts of linear, logical, analytical talents measured by SATs and deployed by CPAs. Our educational systems, as well as science in general, tends to neglect the nonverbal form of intellect. What it comes down to is that modern society discriminates against the right hemisphere.

But now computers can emulate many of the sequential skills of the left hemisphere - it is, at the end of the day, a part that can only see the individual trees in a forest, and machines can do this admirably well. In addition, much of the left-brain-centric work that the information workers of the western world once did — computer programming, financial accounting, routing calls — is now done more cheaply in Asia and elsewhere. To paraphrase a popular saying, "If it can be outsourced or automated, it probably has been. If it has not been, the day is not far off when it will be."

In a world upended by outsourcing, deluged with data, and choked with choices, the abilities that matter most are now closer in spirit to the specialties of the right hemisphere - artistry, imagination, empathy, seeing the big picture, and pursuing the transcendent. This situation has led many to argue that it’s time for our imaginative right brain to take center stage.

No, there is not yet an organization named "Right Brain, the Right Way". No, there is no slogan yet on everyone's lips that reads "It's the Right Brain, Stupid". But yes, there are a number of small efforts underway to make people worldwide realise that the poor cousin is actually the rich cousin of the future.

So you should not be surprised that business executives are turning to the original pop culture icon of right-brain thinking, “Drawing on the Right Side of the Brain,” for guidance into their right minds. You should not be surprised either if a couple of years down the line your left brain subtly reminds you that you had started ignoring it of late

Dr. Sperry summarised it best when he accepted the Nobel Prize in medicine in 1981 for his discoveries concerning the functional specialization of the cerebral hemispheres. “The great pleasure and feeling in my right brain,” he said, “is more than my left brain can find the words to tell you."

In future, if people start firing up their right brains, our human race stops being a bunch of androids and we become an imaginative race once again, you know to whom the most credit should go - computers.

Through new research, standards and tools, the industry is just starting to address what's being called a software gap between a rising tide of multicore processors and a lack of parallel programming tools and techniques to make use of them. This gap came into stark focus in the embedded world at the Multicore Expo recently, where chip makers Freescale, Intel and MIPS and a handful of silicon startups sketched out directions for their multicore products. Others warned that the industry has its work cut out for it delivering the software that will harness the next-generation chips.

About 55 percent of embedded system developers surveyed by VDC said they are using or will use multicore processors in the next 12 months. In the PC market, the figures are even more dramatic. About 40 percent of all processors Intel shipped in 2007 used multiple cores, but that will rise to 95 percent in 2011, said Doug Davis, general manager of Intel's embedded group.

But on the software side, vendors reported that only about 6 percent of their tools were ready for parallel chips in 2007, a figure that will only rise to 40 percent in 2011, VDC said.

In-vehicle networking is creating a quiet revolution in automotive technology. It has eliminated bulky wiring harnesses once used for control circuits and enabled dozens of convenience features such as anti-skid braking systems, airbags, engine control, transmission control, and electric power steering.

In the future, networks will deliver operational data such as lane departure warnings and road condition advisories while allowing drivers and passengers to enjoy their journey more than ever before. Networking is also critical to environmentally friendly hybrid vehicles, which depend on fast, reliable inter-communication between components. Battery systems need charging and power management, and hybrids also require precise coordination between the electric motor and gasoline engine.

Until very recently, commercial high-level tools to support the development of technical computing applications for high-performance systems did not exist. Parallel programming was an esoteric art applied by specialists who focused on achieving maximum performance by using custom setups and low-level libraries and by tuning their applications for specific hardware.

In a 2007 briefing, IDC highlighted the difficulty of scaling beyond a single node because of the lack of appropriate programming environments.[1] Today, as high-performance systems become more prevalent, there is an urgent need to make these systems more readily programmable by all.

To that end, parallel programming solutions must focus beyond custom algorithms and performance. Ecosystems of tools are being developed that assist engineers in the design, development, and debugging of parallel applications and that fully utilize the capabilities of rapidly evolving hardware. To succeed, these new ecosystems, need to do a number of things, which are explained in this report

Sun Microsystems, Inc. has been awarded $44.29 million funding for a five and a half-year research project focused on microchip interconnectivity via on-chip optical networks enabled by Silicon photonics and proximity communication. Part of DARPA's Ultraperformance Nanophotonic Intrachip Communication program, the project commences with an incremental delivery of $8.1 million to Sun Microsystems' Microelectronics and Laboratories divisions

Building on research done under DARPA's High Productivity Computing Systems program, Sun's new project will accelerate the development of lower cost, high performance and high productivity systems. The project presents a unique opportunity to develop supercomputers through interconnecting an array of low-cost chips, with the potential to overcome the fundamental cost and performance limits of scaling up today's large computer systems

"DARPA's UNIC (Ultraperformance Nanophotonic Intrachip Communications) program will demonstrate high performance photonic technology for high bandwidth, on-chip, photonic communications networks for advanced (≥ 10 trillion operations/second) microprocessors. By restoring the balance between computation and communications, the program will significantly enhance DoD's capabilities for applications such as Image Processing, Autonomous Operations, Synthetic Aperture Radar, as well as supercomputing," said Dr. Jag Shah, program manager in DARPA's Microsystems Technology Office.

Recently scientists have provided a sneak preview of the future of biomedicine with a range of projects seeking to assemble virtual humans — or parts of them — on computers and “labs on a chip.” Someday, the descendants of these sophisticated new programs and devices could serve as our stand-ins for clinical tests on drugs, cosmetics and toxic compounds.

The increasing ability of computers and biochips to mimic brain chemistry, internal organs, and the interactions between drugs and viruses such as HIV could help reduce the reliance on animal testing to understand the potency and side effects of pharmaceuticals. A more informed leap between experiments on dish-grown cells and lab animals, in turn, could lead to a better drug development process. And eventually, the technology could usher in a new era of personalized medicine in which rapid tests tell doctors which treatments have the best chances of success for individual patients.

An unusual observation in a University of Central Florida physics lab may lead to a new generation of quantum computers that will render today's computer and credit card encryption technology obsolete.

The basis for current encryption systems is that computers would need thousands of years to factor a large number, making it very difficult to do. However, if UCF Professor Enrique del Barco's observation can be fully understood and applied, scientists may have the basis to create quantum computers -- which could easily break the most complicated encryption in a matter of hours.

Del Barco said the observation may foster the understanding of quantum tunneling of nanoscale magnetic systems, which could revolutionize the way we understand computation.

According to quantum mechanics, small magnetic objects called nanomagnets can exist in two distinct states. They can switch their state through a phenomenon called quantum tunneling. switch is called quantum tunneling because it looks like a funnel cloud tunneling from one pole to another.

Del Barco published paper shows that two almost independent halves of a new magnetic molecule can tunnel, or switch poles, at once under certain conditions. In the process, they appear to cancel out quantum tunneling. This is somewhat similar in concept to what can be observed when two rays of light run into interference. Once the they run into the interference you can expect darkness.

Essentially, what this simultaneous tunneling means is that quantum tunneling can be controlled. Controlling quantum tunneling shifts could help create the quantum logic gates necessary to create quantum computers.

Quantum computers, if they become a reality, could have such dramatically enhanced processing speeds that some of the operations that are today considered to take an inconsiderably long time can be completed much quicker. This is mostly good, but sometimes such phenomenally faster computers could also create problems. Quantum computers, for instance, can also make much of today's credit card encryption technologies obsolete!

Nanochip's new flash memory technology applies to USB drives, solid-state disk drives, and even enterprise servers. A new kind of flash memory technology with potentially greater capacity and durability, lower power requirements, and the same design as flash NAND is primed to challenge today's solid-state disk products.

Fremont, Calif.-based Nanochip said it has made breakthroughs in its array-based memory research that will enable it to deliver working prototypes to potential manufacturing partners next year. Three investors, including Intel Capital, recently put $14 million into the company, which has been developing the technology since its founding in 1996.

"It's a technology that doesn't depend on Moore's Law," says Gordon Knight, CEO of Nanochip. "This technology should go at least 10 generations."

A European consortium has drafted a roadmap for the future of sound and music computing (SMC), which provides the core technologies for the burgeoning electronic music industry

Drawing on inspiration from hard sciences like physics and engineering, social sciences like psychology and musicology, and the creative arts, digital musical instruments, CDs, MP3s and other innovative ICTs owe a great debt to SMC.

The new roadmap published by the S2S² project aims to maximise SMC's growth potential.

Five key challenges have been identified by the roadmap:

Design better sound objects and environments (improving the sounds produced by objects present in our environment to enhance their emotional character).
Understand, model and improve human interaction with sound and music.
Train multidisciplinary researchers in a multicultural society.
Improve knowledge transfer.

Microsoft and Intel are donating $20 million to two U.S. universities for parallel-computing research.

Imagine a man you know but whose name you can't remember approaches you, and your mobile phone uses face-recognition capability to give you his name and information about him before he says hello. This is the kind of application that researchers hope will be developed from US$20 million Microsoft and Intel are giving two U.S. universities for research on parallel computing.

The companies are donating the money to Universal Parallel Computing Research Centers (UPCRCs) at the University of California Berkeley and the University of Illinois at Urbana-Champaign. The centers are aimed at tackling the challenges of programming for processors that have more than one core and so can carry out more than one set of program instructions at a time, a scenario known as parallel computing.

IBM's director of R&D is shifting the tech giant's focus—and making a few enormous bets

IBM is already considered one of the world's best corporate research labs. Yet John Kelly, a 27-year IBM veteran who took over as research director in July, is planning surprisingly dramatic changes. "We have to do bolder things, bigger things," he says, speaking about his plans publicly for the first time. "If we don't fail a third of the time, we're not stretching enough. On the other hand, when we win, we need to win big."

What does Kelly have in mind? For starters, he's focusing on four top research priorities, rather than spreading investments too thin. The four bets are enormous, though. Each of the projects will get $100 million over the next two to three years, in hopes of generating at least $1 billion, each, in new revenue. The projects: inventing a successor to today's semiconductor, designing computers that process data much more efficiently, using math to solve complex business problems, and building massive clusters of computers that operate like a single machine—an approach called "cloud" computing. Central to the effort will be even more emphasis on basic scientific research, such as physics, chemistry, and math.

Bruno Michel has experienced climate change firsthand. As a mountaineer who treks up snow-capped peaks in the Swiss Alps on skis covered with goat skins, he has watched the famed Aletsch Glacier shrink year after year. That's a prime motivator for his work as a researcher at IBM's (IBM) Zurich Lab.

Michel, who has a PhD in biochemistry from the University of Zurich, uses biological principles to deal with the problem of heat in computing. He is designing devices that cool chips using liquid delivered through capillary-like circulation systems—much as the human vascular system cools our bodies.
