Researchers at Oregon State University say they have solved a puzzle in fundamental material science that has eluded scientists since the 1960s, by creating a high-performance “metal-insulator-metal” diode which will speed up transistors and help power tomorrow's faster technology.
According to the university, conventional electronics made with semiconductors use transistors that help control the flow of electrons. Although they are fast and comparatively inexpensive, this approach is limited by the speed with which electrons can move through these materials. With the invention of faster computers and more sophisticated products such as liquid crystal displays, current technologies are nearing the limit of what they can do.

Murata has created two tiny energy-harvesting devices, which it hopes will provide electricity for sensors and wireless components getting rid of the need for an external power supply.
The two devices, one which generates electricity from small vibrations, and the other from faint light sources, follow previous work when it came up with a product that generates electricity from thermal differentials — and another that uses a piezoelectric element to convert pressure into electricity.
The two creations will be put to market from 2011, with Murata hoping they will be used in a broad range of fields, including industrial equipment and cars.

Four driverless electric vans successfully ended a 13,000-kilometre test drive from Italy to China which mirrored the journey from East to West carried out by Marco Polo in the Middle Ages.
The four vans, packed with navigation gear and other computer software drove themselves Across Eastern Europe, Russia, Kazakhstan and the Gobi Desert without getting lost.
The vans arrived at Shanghai Expo. They had been equipped with four solar-powered laser scanners and seven video cameras that work together to detect and avoid obstacles.
It was all part of an experiment aimed at improving road safety and advancing automotive technology.

It's what every mountaineer wants they reach the summit of Mount Everest, 3G high speed communication. "Hi honey, I'm on top of the world".
Those who have trekked it to the top will soon able to call their mates, go on Facebook or Twitter and boast that they've got there thanks to TeliaSonera and its subsidiary in Nepal, Ncell, which have bought 3G to the Mount Everest area.
Climbers who reached Everest's 8,848-metre peak previously depended on expensive and erratic satellite phone coverage and a voice-only network set up by China Mobile in 2007 on the Chinese side of the mountain.

A standardisation of coding for automated trading programs, which allows trading algorithms to be developed substantially quicker, could revolutionise the stock market.
Trading algorithms have become increasingly commonplace as firms have realised the potential to offer a fast way to spot, and act upon, market opportunities. Now new coding, dubbed FIXatdl, offers a way to reduce the time between the conception and implementation of putting new and revised algorithms in place.
The algorithms offer the advantage of being quicker and more reliable than stock market traders, as well as also not actually being stock market traders, which is presumably at least part of the reason behind development.

Scientists are trying to create some of the tiniest lithium-ion batteries on earth which will be no bigger than a grain of sand.
The research, funded by DARPA, aims to reduce the size of lithium-ion batteries, commonly used in electrical goods, so they can be used to power electronics and mechanical components of micro- to nano-scale devices.
Jane Chang, an engineer at the University of California, Los Angeles, is designing one component: the electrolyte that allows charge to flow between electrodes.
"We're trying to achieve the same power densities, the same energy densities as traditional lithium ion batteries, but we need to make the footprint much smaller," she said.

Cameron has announced Whitehall will spend £1 billion on "cyber defence". A Home Security spokesman in the US has said that it needs to wise up the cyber threat. We've been talking to some cyber security experts, anonymous and with either direct access to, or access to those with direct access to, top level government agencies in both the United States and the UK. Guess what? Defence don't mean defence.
Meetings have been going on and continue about the possibilities of using cyber attacks as weapons. We're not just talking Stuxnet, which is believed by many to have come from Israel, China or the US to sabotage Iranian and/or Indian infrastructure, but botnets too. "Defence" agents don't just want to know how to neutralise a threat, but how to gain access to and control the world's largest botnets to point at who they need to.
"You would be a fool," one source suggested to us this week, "to think that governments are not considering the applications for cyber warfare."
Earlier on in the week someone else close to the matter, who also wished to be anonymous — you'd be mad not to remain anonymous — told us that attacks on hospitals and power grids are "likely". In fact attacks on hospitals are happening already. All of this must be kept under wraps — if attackers know they're causing trouble that's cause for celebr

Recently TechEye was hit by a particularly nasty DDOS. At first we, deluded as always, thought our servers were getting a thumping from Slashdot. The attackers will be happy to know that it took us time, effort and yes, dosh, to scramble around trying to fix it. WebScreen, which as far as we are aware is the only outfit offering thorough DDOS protection in the UK, jumped to our rescue. Thank you WebScreen. Anyway — TechEye decided it would be a good idea to have a chat with Paul Bristow, Chief Operating Officer.
"All DDOS attacks in the early days were from organised crime to put rivals in online gaming or pornography out of business, or to extort money," Bristow tells TechEye "but the whole thing has moved on now."
There are websites you can go onto where you provide your credit card details and that will let you hire a botnet for an hour. It's fact, says Webscreen, that you can even take a three minute try before you buy — just to show you that it works. These services play in their own back yard, employing the capabilities of attackers in the places you'd expect — China, Russia, India. But the services themselves are sold to target local businesses.

Whistleblowing site, Wikileaks claims that the US government is mounting a dirty tricks campaign to kill off its funding.
Moneybookers, a British-registered internet payment company that collects Wikileaks donations, has told the outfit that its account had been closed because it had been put on an official US watchlist and on an Australian government blacklist.
But if the story is true then Wikileaks has sat on the information for months. According to the Manchester Guardian, the blacklisting came a few days after the Pentagon publicly fumed at Wikileaks for obtaining thousands of classified military documents about the war in Afghanistan,
Moneybookers shut down Wikileaks account on 13 August which means that the outfit sat on the information for some time before going public.

Some of the poorest countries in the world are suffering from a “digital lag” of 17 years, according to a UN report.
And companies need to work with governments to get things moving.
Professor Richard Heeks of the University of Manchester, who contributed extensively to the 2010 Information Economy Report from the UN Conference on Trade and Development, (UNCTAD) warned: “Even with current high growth rates, our calculations show that it will be 2019 before the poorest countries achieve the internet usage rates reached by the richest countries in 2002.
"That's a 'digital lag' of 17 years so governments and private firms must work together to improve access.
"We have to change our view of the world's poor from one that sees them as passive consumers of ICTs, to one that sees them as producers of and innovators with the technology.
Professor Heeks said the mobile phone market was growing at 50 percent or more in some African countries, with 3G and broadband likely to be rolled out at a slightly slower rate.
He added: “The poor will spend up to 75% of their disposable income on running a mobile."

A new report from rights group Students & Scholars Against Corporate Misbehavior (SACOM) says conditions at the notorious Shenzhen factory in China have not improved.
Despite public breast-beating and treats for staff such as days out at worker rallies — what fun! -Foxconn and its customers, which include Apple, HP and Dell, are still treating workers as machines, says SACOM.
The organisation interviewed 100 Foxconn workers to reach its conclusions, and says, most notably, that the promised pay rise to Y2,000 per month has failed to materialise — indeed, most workers haven't even been told about it.
"This is the result of permanent pressure from buyers on their suppliers to produce cheaper," says Chantal Peyer, from the Swiss NGO Bread for All, which supports the findings of the report.

Carnegie Mellon University has taught a computer how to read and learn from the internet.
According to Dennis Baron at the Oxford University press blog, the computer is called NELL and it is reading the internet and learning from it in much the same way that humans learn language and acquire knowledge. Basically by soaking it all up and figuring it out.
NELL is short for Never Ending Language Learner and apparently it is getting brainier every day.

While the tame Apple press is doing its level best to write off Microsoft's Windows Mobile 7 in case it upsets Jobs' Mob's cash cow, it seems that Ballmers' boys are doing their best to miff developers.
An icon for the mobile game Angry Birds appeared in a Windows Phone 7 promotional image.
Many assumed the game would be on Redmond's new smartphones. However, the people behind Angry Birds were incandescent with rage and , ironically, tweeted a denial of any commitment to Windows Mobile 7.
