Cornell bioengineers and Weill Cornell Medical College physicians have created an artificial ear that looks and acts like a natural ear, giving new hope to thousands of children born with a congenital deformity called microtia.
They used 3-D printing and injectable gels made of living cells to fashion ears that are practically identical to a human ear.
Over a three-month period, these flexible ears… read more
A new method of capturing images based on a flat, flexible, transparent, and potentially disposable polymer sheet has been developed by a team of researchers at Johannes Kepler University Linz in Austria.
The new imager, which resembles a flexible plastic film, uses fluorescent particles to capture incoming light and channel a portion of it to an array of sensors framing the sheet.
With no electronics or internal components,… read more
The PlayStation 4, as you’d expect for a seven-years-later follow-up, has impressively bumped specs. An eight-core X86 AMD “Jaguar” CPU and a 1.84 Teraflop AMD Radeon graphics engine (with “18 compute units”) comprise the central processing on the PS4, CNET reports.
There’s also 8GB of fast GDDR5 memory. The PS4 will use a hard drive for storage versus an SSD, but the included capacity in the box… read more
Mitchell Lerner at the University of Pennsylvania and associates have revealed a technique that uses an array of carbon nanotube transistors on a silicon chip to detect a biomarker of prostate cancer known as osteopontin (OPN), The Physics arXiv Blog reports.
The transistor can detect OPN at concentrations of 1 picogram per milliliter — a concentration three orders of magnitude weaker than ELISA can manage. ELISA is the… read more
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
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
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
“We’re looking for bold, creative individuals who want to join us and be a part of shaping the future of Glass,” says the Google Glass team.
“We’d love to make everyone an Explorer, but we’re starting off a bit smaller. We’re still in the early stages, and while we can’t promise everything will be perfect, we can promise it will be exciting.”
“Using Google+… read more
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
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
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
Big news in the search for dark matter may be coming in about two weeks, the leader of a space-based particle physics experiment said Feb. 17 at the annual meeting of the American Association for the Advancement of Science, Space.com reports.
That’s when the first paper of results from the Alpha Magnetic Spectrometer, a particle collector mounted on the outside of the International Space Station,… read more
