A Form-Fitting Photovoltaic Artificial Retina

Several teams of scientists and engineers have been trying for years to produce a practical retinal prosthesis for people afflicted by a progressive loss of photoreceptor cells. One problem all the researchers face is how to get power and data to a retinal chip that’s implanted at the back of a person’s eye. Some groups’ implants, such as those from the University of Southern California’s Doheny Eye Institute and an MIT-Harvard team get their power and data from RF signals beamed in from the outside, while other groups, including one at the University Eye Hospital in T?ºbingen, Germany, are working on getting the data as light entering the eye using RF energy to beam in the power. But a team from Stanford University has been working on what might seem like the obvious solution: using light entering the eye for both power and data

China Launches World’s Fastest Train Service

China on Saturday launched what it described as the world’s fastest train service covering a distance of 1,068 kms at the average speed of 350 kms an hour. The distance between Wuhan in central China and Guangzhou in the country’s south was covered by the high-speed train in two hours forty five minutes. The new service will cut the travel time between these cities by more than six hours. The train reached a maximum speed of 394.2 km per hour during trail runs that begun on December 9. The commercial operation was launched today with two trains covering the distance while passing through 20 different cities along the route

Good Guys Bring Down the Mega-D Botnet

For two years as a researcher with security company FireEye, Atif Mushtaq worked to keep Mega-D bot malware from infecting clients’ networks. In the process, he learned how its controllers operated it. Last June, he began publishing his findings online. In November, he suddenly switched from defence to offence. And Mega-D — a powerful, resilient botnet that had forced 250,000 PCs to do its bidding — went down

The Secret Lives of Amazon’s Elves

If Amazon is Santa, then the 400 folks living in RVs outside the Coffeyville, KS fulfillment center at Christmas time are the elves. Amazon didn’t always lure in workcampers from the RV community with the promise of free campgrounds and $10.50-$11 an hour seasonal jobs. Amazon had a bad experience busing in people from Tulsa, explained tech nomad Chris Dunphy. There was a lot of theft and a lot of people who weren’t really serious. Workers from Tulsa were adding a 4-hour round-trip commute to a grueling 10-to-12 hour shift, Cherie Ve Ard added. They’d get there exhausted. The work wasn’t exactly what Cherie had envisioned — via Slashdot

BBC’s Plan To Kick Open Source Out of UK TV

Generally speaking, the BBC isn’t allowed to encrypt or restrict its broadcasts: the license fee payer pays for these broadcasts. But the BBC has tried to get around this, asking Ofcom for permission to encrypt the metadata on its broadcasts — including the assistive information used by deaf and blind people and the ‘tables’ used by receivers to play back the video. As Ofcom gears up to a second consultation on the issue, there’s one important question that the BBC must answer if the implications of this move are to be fully explored, namely: How can free/open source software co-exist with a plan to put DRM on broadcasts? — via Slashdot

Microsoft Word Remains Under Scrutiny After Patent Loss

i4i, the Canadian developer that won a $290 million court judgment against Microsoft, will be going over future Microsoft software extremely carefully to make sure its patent hasn’t been infringed. Although Loudon Owen declined to say whether his company’s software engineers had been picking through Office 2010 — which Microsoft said did not use i4i’s Custom XML technology — he promised that they would be looking at all Microsoft software for evidence of wrongdoing. Microsoft released a public beta of Office 2010 in mid-November

Is Neurostim Becoming a Reality?

There is a current mass market for cognitive enhancement products — and arguments about the black market potential for neurostim. The same neurostim device that uses electric impulses from a brain implant to treat people with Parkinson’s Disease can be tweaked by a few millimeters and pulse rates to make cocaine addicts feel like they are high all the time… Mix the glamour of surgical self-improvement with the geekiness of high-tech gadget fetishism and you have a niche cosmetic neurostim market waiting to be tapped… — via Slashdot

Amazon’s Kindle Has Copyright Protection Hacked

An Israeli hacker claims to have broken the copyright protection on Amazon’s Kindle e-reader. The hack will allow the ebooks stored on the reader to be transferred as pdf files to any other device. The hacker, known as Labba, responded to a challenge posted on Israeli hacking forum, hacking.org. It is the latest in a series of Digital Rights Management hacks, the most famous being the reverse engineering of iTunes

Calling on Leakers to Help Document Local Misdeeds

The time has come for WikiLeaks, which calls itself the first intelligence agency of the people, to think locally, says Daniel Schmitt, a German computer engineer who is a full-time unpaid spokesman for the Web site. We are trying to bring WikiLeaks more directly to communities, he said in a telephone interview. The organisation has applied for a $532,000 two-year grant from the Knight Foundation to expand the use of its secure, anonymous submission system by local newspapers. The foundation’s News Challenge will give as much as $5 million this year to projects that use digital technology to transform community news. WikiLeaks proposes using the grant to encourage local newspapers to include a link to WikiLeaks’ secure, anonymous servers so that readers can submit documents on local issues or scandals. The newspapers would have first crack at the material, and after a period of timeperhaps two weeks, Schmitt saidthe documents would be made public on the main WikiLeaks page

Colour-Shifting Contact Lenses Alert Diabetics to Glucose Levels

Diabetics are saddled with the unenviable task of checking their blood sugar levels constantly, usually through a repeated ritual of pin-pricks and blood drawing. But a new non-invasive technology developed by a biochemical engineer at the University of Western Ontario lets diabetics keep tabs on their glucose levels with contact lenses that change colours as their blood sugar rises and falls

Firefox 3.5 Now the Most Popular Browser Worldwide

StatCounter Global Statistics shows that in the last few days Firefox 3.5 became the most used browser version worldwide, edging ahead of IE7. IE8 is rising fast (along with Windows 7), but over the last few months the slope of Firefox’s worldwide curve has been steeper. In the US, IE8 has always been ahead of Firefox 3.5; in Europe Firefox has led since late summer — via Slashdot

Microsoft Sued Over Bing Trademark

A small design company in America has filed a lawsuit against Microsoft, alleging that it is unfairly using the Bing name for its search engine. Bing! Information Design, based in St Louis, Missouri, launched a legal action last week in a local court — alleging that the multibillion-dollar software corporation had knowledge of the mark and intentionally interfered when it relaunched its search engine with a new name earlier this year

Complex Integrated Circuits Made of Carbon Nanotubes

The first three-dimensional carbon nanotube circuits, made by researchers at Stanford University, could be an important step in making nanotube computers that could be faster and use less power than today’s silicon chips. Such a computer is still at least 10 years off, but the Stanford work shows it is possible to make stacked circuits using carbon nanotubes. Stacked circuits cram more processing power in a given area, and also do a better job dissipating waste heat

Tooth-Mounted Hearing Aid for the Masses

Sonitus Medical of San Mateo in California has created a small device that wraps around the teeth. It picks up the sounds detected from a tiny microphone in the deaf ear and transforms them into vibrations. These then travel through the teeth and down the jawbone to the cochlea in the working ear, where they are transmitted to the brain providing stereo sound. The same process of bone conduction explains how we hear our own voices, and why they sound different when they are recorded and played back to us. Some existing hearing aids also use bone conduction to transmit sounds to the cochlea, but these either require a titanium post to be drilled into the skull, or rely on cumbersome headsets. It also differs from conventional hearing aids, which employ air conduction to simply turn up the volume of sound travelling into the ear. The Cleveland Clinic in Ohio voted Sonitus’s device its top medical innovation for 2010
