Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability

primary purpose was to explore an efficient and versatile means to merge electronics with tissue

used 3D printing of cells and nanoparticles followed by cell culture to combine a small coil antenna with cartilage, creating what they term a bionic ear.

This silicon wafer consists of glucose fuel cells of varying sizes; the largest is 64 by 64 mm

MIT engineers have developed a fuel cell that runs on the same sugar that powers human cells: glucose

This glucose fuel cell could be used to drive highly efficient brain implants of the future, which could help paralyzed patients move their arms and legs again

scheduled to be launched to orbit in second half of 2013

Student Satellite is an educational project that university and high school students can participate in

The CubeSat standard for nanosatellites was followed during the engineering of ESTCube-1, resulting in a 10x10x11.35 cm cube, with a volume of 1 liter and a mass of 1.048 kg.

Family Portrait Of The Planets

In 1990, the U.S. space probe Voyager I , while heading out to the edge of the Solar System, at 5:12pm PST began a four-hour series of photographs in a look backward which captured the Sun and six planets. An elongated large mozaic was later made by combining about 60 images. In this first “Family Portrait of the Planets”, the Sun appeared almost star-like and the planets were mere dots. Mercury was too close to the sun to photograph. Mars and Pluto, were too small to resolve. This first record of the Solar System from space may remain the only one for decades to follow. Voyager I had a unique lofty perspective, looking down on the plane in which the planets orbit. It had been steadily climbing since it passed Saturn in 1980, and reached an angle of 32 degrees high above the plane of the solar system

A $2 billion cosmic ray detector on the International Space Station has found the footprint of something that could be dark matter

the evidence isn't enough to declare the case closed

And after two years, the first evidence came in Wednesday: tantalizing cosmic footprints that seem to have been left by dark matter.

By connecting a new flexible, thin-film Li-ion battery to a flexible organic LED, a team of researchers from South Korea has demonstrated the first fully functional all-flexible electronic system

total integration of a flexible display and battery on a single plastic substrate without the help of bulk electronics

relies on a new fabrication method that enables flexible batteries to work with a variety of electrode materials, overcoming previous electrode limitations

Research suggests that anywhere from six to 100 U.S. airline passengers each year could get cancer from the machines.

Because of a regulatory Catch-22, the airport X-ray scanners have escaped the oversight required for X-ray machines used in doctors’ offices and hospitals. The reason is that the scanners do not have a medical purpose, so the FDA cannot subject them to the rigorous evaluation it applies to medical devices.

tiny implant that is inserted into the eye and attached to the retina in a minimally invasive procedure no more complicated than conventional cataract surgery

consists of photodetectors, microelectrodes and electronic circuitry that act together to replace the eye’s natural photoreceptors that have been damaged by AMD and feed visual information to the brain

photoreceptors in a healthy retina convert light into a series of electrical signals which are transmitted to the brain via complex neural pathways

Ultracold crystals designed to catch particles of dark matter deep underground have come up with three potential detections

The researchers do not have enough evidence to say they have discovered dark matter particles

Theoretical physicists have put forth some ideas for particles that might constitute dark matter, including one called a weakly interacting massive particle, or WIMP.

Most people believe they can multitask effectively, but a

study indicates that people who multitask the most – including talking on a cell phone while driving – are least capable of doing so.

data suggest the people talking on cell phones while driving are people who probably shouldn't. We showed that people who multitask the most are those who appear to be the least capable of multitasking effectively

Thanks to the flexible yet robust properties of carbon nanotubes, researchers have previously fabricated transistors that can be rolled, folded, and stretched

Japan has made an all-carbon-nanotube transistor that can be crumpled like a piece of paper without degradation of its electrical properties
