The devices are less than 100 microns thick, the average diameter of a human hair. They consist of circuitry embedded in a layer or rubbery polyester that allow them to stretch, bend and wrinkle. They are barely visible when placed on skin, making them easy to conceal from others.

The devices can detect electrical signals linked with brain waves, and incorporate solar cells for power and antennas that allow… read more

MIT researchers build ultrahigh-definition Quad HD (4K) TV chip

February 21, 2013

uhd_quadhd_mit

At the International Solid-State Circuits Conference this week, MIT researchers unveiled their own Quad HD video chip design.

Quad HD is also known as 4K and ultrahigh-definition (UHD). The new Quad HD video standard enables a fourfold increase in the resolution of TV screens.

At the Consumer Electronics Show (CES) in January, several manufacturers debuted new UHD models.

There is no UHD content… read more

Electrical engineers at Oregon State University have discovered a new method, called acoustic-assisted magnetic recording, to use high-frequency sound waves to create durable solid state storage that allows for storing more data in a smaller space, using less power.

“We’re near the peak of what we can do with the technology we now use for magnetic storage,” said Pallavi Dhagat, an associate professor in the… read more

Water on the moon: it’s been there all along

February 21, 2013

Traces of water have been detected within the crystalline structure of mineral samples from the lunar highland upper crust obtained during the Apollo missions, according to a University of Michigan researcher and his colleagues.

The lunar highlands are thought to represent the original crust, crystallized from a magma ocean on a mostly molten early moon. The new findings indicate that the early moon was wet and that water there… read more

Stanford scientists fit light-emitting bioprobe in a living cell

Light-based probes can be inserted without damage to the cell, could have profound impact on biological research
February 20, 2013

This image shows a photonic nanobeam inserted in a cell. Clearly visible are the etched holes through the beam as well as the sandwich-like layer structure of the beam itself. The beam structure alternates between layers of gallium arsenide and photonic crystal containing the light-producing quantum dots. (Photo credit: Gary Shambat, Stanford School of Engineering)

Stanford engineers have developed a new class of biophotonic (light-emitting) probes small enough to be injected into individual cells for intracellular sensing and control, without harm to the host.

The researchers call their device a “nanobeam,” because it resembles a steel I-beam with a series of round holes etched through the center. This beam, however, is not massive, but measures only a few microns in length and… read more

Stay cool and live longer?

Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why

Roundworms' secret of long life: being cool (credit: The Goldstein Lab)

Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms (nematodes) in cold environments — and this genetic program also exists in warm-blooded animals, including humans.

“This raises the intriguing possibility that exposure to cold air — or pharmacological stimulation of the cold-sensitive genetic program — may promote longevity in mammals,” said… read more

New self-driving car system tested on UK roads

February 20, 2013

Self-driving RobotCar

Scientists at Oxford University have developed a self-driving car that can cope with snow, rain and other weather conditions. The system can be fitted to existing cars and could one day cost just £100 (US$150), The Guardian reports.

The new system has been installed in a Nissan Leaf electric car and tested on private roads around the university. It will halt for pedestrians, and could take over… read more

In the search for renewable alternatives to gasoline, heavy alcohols such as isobutanol are promising candidates.

They contain more energy than ethanol and are also more compatible with existing gasoline-based infrastructure.

For isobutanol to become practical, however, scientists need a way to reliably produce huge quantities of it from renewable sources.

MIT chemical engineers and biologists have now devised a way… read more

Researchers from North Carolina State University have for the first time successfully coated polymer implants with a bioactive film.

The discovery should improve the success rate of such implants, which are often used in spinal surgeries.

The polymer used in polymer (plastic) implants, called PEEK, does not bond well with bone or other tissues in the body. This can result in the implant rubbing… read more

Soft arrays of miniature electrodes for improved Parkinson’s treatment

February 19, 2013

Microelectode_Enhanced_Probe

Miniature, ultra-flexible electrodes could be the answer to more successful treatment for Parkinson’s diseases, according to Professor Philippe Renaud of the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.

He has developed soft arrays of miniature electrodes in his Microsystems Laboratory that open new possibilities for more accurate and local deep brain stimulation (DBS).

Some 90,000 patients per year are treated for Parkinson’s disease, a number that… read more

New therapy uses alternating current to cancel out Parkinson tremors

February 19, 2013

corticol stimulation

A new therapy could help suppress tremors in people with Parkinson’s disease, an Oxford University study suggests.

The technique — called transcranial alternating current stimulation (TACS) — cancels out the brain signal causing the tremors by applying a small, safe electric current across electrodes on the outside of a patient’s head.

In a preliminary study, conducted with 15 people with Parkinson’s disease at Oxford‘s John Radcliffe… read more
