The water cooling technology was built into IBM's 3D chips
Enlarge Image
A network of tiny pipes of water could be used to cool next-generation PC chips, researchers at IBM have said.
Scientists at the firm have shown off a prototype device layered with thousands of "hair-width" cooling arteries.
They believe it could be a solution to the increasing amount of heat pumped out by chips as they become smaller and more densely packed with components.
The technology was demonstrated in IBM's 3D chips, where circuits are stacked one on top of the other.
Laying chips vertically, instead of side by side, reduces the distance data has to travel , enhancing performance and saving critical space.
"As we package chips on top of each other....we have found that conventional coolers attached to the back of a chip don't scale," explained Thomas Brunschwiler at IBM's Zurich Research Laboratory.
"In order to exploit the potential of high-performance 3D chip stacking, we need interlayer cooling."
Cool running
Heat is seen as one of the major hurdles of producing ever smaller and quicker chips.
3D chip
It took IBM a decade to work out how to build 3D chips
It is the by-product of the movement of electrons through the tiny wires connecting the millions of components on a modern processor.
As more and more components are packed on to chips - Intel recently launched a processor with two billion transistors, for example - the problems become worse.
As a result, researchers around the world are engaged in a search for the most efficient way to take the heat off the chip industry.
For example, in 2007, US researchers built tiny wind engines that created a "breeze" made up of charged particles, or ions, to cool computer chips.
But the problems are exacerbated in the multi-storey chips which IBM, as well as others, believe offer "one of the most promising approaches" for building future processors.
Each 4cm sq sandwich is just 1mm thick but pumps out close to 1kilowatt - 10 times that generated by a hotplate.
Conventional cooling techniques such as fans and heat sinks do not work as well with the 3D technology, particularly as heat has to be drawn away from between the individual chips.
To get around this, researchers piped water through sealed tubes just 50 microns (millionths of a metre) in diameter, between individual layers.
Water is much more efficient than air at absorbing heat and so even with tiny amounts of liquid flowing through the system the researchers saw a significant effect.
The idea of pumping liquids around computers is not entirely new. Early mainframe computers had water pumped around them.
High end computers have been "modded" for a number of years with water coolers and various researchers and companies have put forward proposals for directly cooling chips with fluids.
In 2003, Stanford University spin-out company Cooligy showed off its Active Micro-Channel Cooling (AMC) technology which allowed fluids to circulate through hundreds of tiny channels on the upper surface of a chip.
The technology was used in some versions of Apple's Power Mac G5 desktop computer, released in 2004.
IBM has said its water-cooling technology could be in products within five years.

100 th bithday to cell phone
History has forgotten Nathan Stubblefield, but thanks to the arrival of the 100th anniversary of his then-pioneering invention, the man's finally receiving his due.
In 1908 Stubblefield had the idea to use a complicated rig of wire and large poles set up around a train track, road, or river. When a train, vehicle, or boat traveled past the wires, a transmitting device on the vehicle would send an audio signal to a receiving device in the distance using magnetic waves.
A patent was granted for the device on May 9 of that year, which some are now crediting as the first wireless communications device ever. To wit, Virgin Mobile is honoring Stubblefield on the centennial of the patent with a set of web pages about the man. (Click through the photo gallery to get a better idea of how such a device worked. It's really pretty fascinating.)
Unfortunately, Stubblefield's invention wasn't entirely practical. The transmitter and receiver were enormous and far from portable (see picture), and they required so much wire that it would have been considerably more efficient to simply run the wire between the two transmitters instead of using wireless communications.
Still, it's nice to remember Stubblefield as a pioneer in a field that, at the time, few felt would have much of a future. History has of course shown of course that Stubblefield was on to something bigger than he knew: Harris Interactive's latest poll shows that 14 percent of adults use a cell phone exclusively at home now, sans land line.

FLASH ON MOBILE- ADOBE WAY
Adobe has announced a plan to try to get its Flash player installed on more mobile devices and set-top boxes.
Dubbed Open Screen the initiative lifts restrictions on how its multimedia handling software can be used.
Adobe will stop charging licencing fees for mobile versions of Flash and plans to publish information about the inner workings of the code.
In taking this step Adobe hopes to repeat on mobiles the success its Flash technology has enjoyed on the web.
Video deal
Adobe estimates that its Flash player is installed on more than 98% of net-connected desktop computers.
The Open Screen plan will build on Flash Lite - Adobe's version of its multimedia player designed for mobile gadgets - that is already on millions of handhelds.
The ultimate aim of Open Screen is to make it much easier for TV and film makers to send their content to mobiles and on other devices such as set-top boxes.
It aims to do this by creating one flexible player technology that can run on any small-form device but only demands that developers write code once for it.
At the moment trying to get games or video on to different devices can be frustrating because of the plethora of hardware and software quirks on each gadget.
Adobe's four-step plan involves ending license fees; removing restrictions on the use of files in SWF and FLV format; publishing detailed information about the program interfaces for its Flash player and opening up information about its Flash streaming technology.
The move is the latest in a series that are aiming to open up Flash and get more devleopers working with it.
It is also part of the larger plan for Adobe Air - an overarching code development system that aims to bridge the gap between web and desktop applications.
Adobe said it was working with Arm, SonyEricsson, Nokia, LG and other gadget makers on the Open Screen initiative as well as content partners such as the BBC, MTV and NBC.
Adobe faces competition from Microsoft which is trying to get Silverlight - its answer to Air - on to mobiles too.

MICROSOFT ON SOFT SIDE TO YAHOO. AWAY FROM BID
Software giant Microsoft has dropped its three-month-old bid to buy internet firm Yahoo because the two sides cannot agree on an acceptable sale price.
Microsoft chief executive Steve Ballmer formally withdrew the offer in a letter to Yahoo chief executive Jerry Yang.
Mr Ballmer said Microsoft had raised its original offer from $44.6bn to $47.5bn (£24.1bn) - $33 per share.
But he added that Yahoo had insisted on at least $53bn, or $37 a share - more than Microsoft was prepared to pay.
The software giant had wanted to do a deal to be able to compete with Google, which dominates the lucrative market for internet advertising.
 |  Microsoft's new leadership will have to prove it can deliver a web offering that can ultimately substitute the profits generated by cash cows Windows and Office 
Tim Weber, Business editor, BBC News website 
|
This market was worth $40bn in 2007 and is predicted to double to $80bn by 2010.
'Distraction'
In his letter to Mr Yang, which has been posted on the Microsoft website, Mr Ballmer said: "We continue to believe that our proposed acquisition made sense for Microsoft, Yahoo and the market as a whole.
"Despite our best efforts, including raising our bid by roughly $5bn, Yahoo has not moved toward accepting our offer.
"After careful consideration, we believe the economics demanded by Yahoo do not make sense for us, and it is in the best interests of Microsoft stockholders, employees and other stakeholders to withdraw our proposal."
Mr Ballmer also told Yahoo's boss that he would not pursue his original plan B of launching a hostile takeover battle, because Mr Yang would "take steps that would make Yahoo undesirable as an acquisition for Microsoft".
Mr Ballmer told his own employees that Microsoft could achieve its goals without Yahoo, albeit at a slower pace.
Yahoo maintained that Microsoft had offered too little to buy the company.
In a statement issued after Microsoft's withdrawal, Yahoo chairman Roy Bostock dismissed the unsolicited bid as a "distraction".
Microsoft's shares closed on Friday virtually unchanged at $29.24. Yahoo's shares were $1.85 higher at $28.67 amid expectations of a higher Microsoft offer.
The BBC's Peter Bowes says analysts believe the breakdown in talks may have an adverse affect on Yahoo shares and generate uncertainty among investors about the company's management.
Disappointment
Sir Martin Sorrell, the chief executive of advertising group WPP, said his clients would be disappointed that Microsoft had abandoned its bid for Yahoo.
"A combination of Microsoft and Yahoo would have provided balance to the online advertising market place," he told the BBC News website.
However, he said that Microsoft was a "resourceful and innovative company" and might still be able to provide a challenge to Google's market dominance.

google, yahoo, micrsoft and game is all done
The bidding for Yahoo!’s future took another twist today when it emerged that Rupert Murdoch’s News Corp was trying to work with Microsoft to find a way they both could get their hands on Yahoo!.
Yahoo!’s rejection of Microsoft’s $31-a-share-offer earlier this week did not please a number of Yahoo!’s investors. Piper Jaffray analyst Gene Munster asked 20 of Yahoo’s Institutional investors their opinion and the majority said they would prefer to deal with Microsoft on that offer, than do no deal at all. The growing feeling among Silicon Valley investors is that a deal will be completed in the next 3-4 weeks.
What that deal will be and what good it will be to whom, remains to be seen. Google is remaining omimously quiet although, Yahoo! is about to turn over three per cent of its US search queries advertising inventory to Google in a two week trial - clearly a little detail that - if you were cynical - might say is being done to annoy Microsoft during its pursuit.
Difficult as it is to keep up with all the twists and turns - Jemima Kiss over at the Guardian has summarised key events here in a neat timeline.

WHAT'S RSS AND HOW TO SUBSCRIBE IT?
We’re often asked for a definition of RSS feeds. Instead of listing lines of definitions and examples, we thought this didactic 3.5 minutes video from CommonCraft provides with a good answer. Nice Job!

Websites gamble on their future
The sheer number of competitors selling any and every product or service means shop sites can struggle to make themselves stand out in the crowd.
In a bid to keep up with the pace an increasing number of websites are turning to insights that have emerged from studies of how to gamble on fruit machines.
Running an online store and gambling on a one-armed bandit may seem to have little in common - beyond the near certainty that you are going to lose money - but there is an affinity that might not at first be apparent.
Research into the so called "bandit problem" has produced techniques that ensure theoretical gamblers get the best possible return.
These techniques funnel most cash into the machine giving the current best payout. But they hedge this bet by pumping some coins into other machines to see if they produce a higher return.
How Twitter makes it real
Unlike many of my friends and colleagues I wasn't able to make it to Austin, Texas for this year's SXSW interactive, the four-day technology conference and festival that is currently firing the imagination of the technology world.
So I wasn't in the ballroom when the keynote address by Facebook founder Mark Zuckerberg went awry under the less-than-forensic questioning of technology journalist Sarah Lacy.
I didn't see the crowd start to get restless and heckle Zuckerberg about the deeply-unpopular Beacon advertising system, or get a chance to grab the microphone and ask questions when Lacy threw the conversation open to the floor.
And yet I was there in another way, listening to and even interacting with some of my friends in the audience, picking up on the vibe in the room and even tuning in later as Sarah Lacy loudly defended herself.
I was there because I was plugged into Twitter, the instant messaging service that lets users send short text messages to anyone who cares to tune in, online or on their mobile phone.
As I sat at my desk a constant stream of 'tweets', as they are called, was being supplied by many of the people in the room and I was able to reply directly and feel that I too was participating.
Nano switch hints at future chips
Researchers have built the world's smallest transistor - one atom thick and 10 atoms wide - out of a material that could one day replace silicon.
The transistor, essentially an on/off switch, has been made using graphene, a two-dimensional material first discovered only four years ago.
Graphene is a single layer of graphite, which is found in the humble pencil.
The transistor is the key building block of microchips and the basis for almost all electronics.
Dr Kostya Novoselov and Professor Andre Geim from The School of Physics and Astronomy at The University of Manchester have been leading research into the potential application of graphene in electronics and were the first to separate a sheet of the material from graphite
Super material
Graphene has been hailed as a super material because it has many potential applications. It is a flat molecule, with only the thickness of an atom, and both very stable and robust.
The researchers are also looking at its use in display technology - because it is transparent.
The Manchester-based scientists have shown that graphene can be carved into tiny electronic circuits with individual transistors not much larger than a molecule.
Dr Novoselov told BBC News that graphene had many advantages over silicon because it could conduct electricity faster and further.

FIREFOX THE FOX WAY. SHOWS OUT THE FLASH URL EMBEDED ON WEB PAGE
www.youthsprouts.blogspot.com
Like that embedded flash animation or game on a website and wanted to have it on your hard disk. You can do that if you are on Firefox. Its very simple, just load the webpage with the embedded flash animation on Firefox and go to Tools -> Page Info. Select the Media tab on the page info box.
A list appears which lists all media contents on the webpage like images, sounds,
flash etc with details like address of the file and the type. Scroll through the list and identify the flash file embedded on the page you want to save. One hint would be that its extension is .swf and it would be listed as 'Embed' type in the list. Once you find out the embedded flash file, select it and click on 'Save As' button below the list to save the file on your hard disk.
