| Posted: 09 Feb 2014 02:31 PM PST NASA's Spitzer and Hubble Space Telescopes have spotted what might be one of the most distant galaxies known, harkening back to a time when our universe was only about 650 million years old (our universe is 13.8 billion years old). The galaxy, known as Abell2744 Y1, is about 30 times smaller than our Milky Way galaxy and is producing about 10 times more stars, as is typical for galaxies in our young universe. |
| Cochlear implant with no exterior hardware can be wirelessly recharged Posted: 09 Feb 2014 12:24 PM PST Cochlear implants -- medical devices that electrically stimulate the auditory nerve -- have granted at least limited hearing to hundreds of thousands of people worldwide who otherwise would be totally deaf. Existing versions of the device, however, require that a disk-shaped transmitter about an inch in diameter be affixed to the skull, with a wire snaking down to a joint microphone and power source that looks like an oversized hearing aid around the patient's ear. Researchers have now developed a new, low-power signal-processing chip that could lead to a cochlear implant that requires no external hardware. |
| Bio scaffolds categorized by characteristic cell shapes Posted: 07 Feb 2014 10:30 AM PST Getting in the right shape might be just as important in a biology lab as a gym. Shape is thought to play an important role in the effectiveness of cells grown to repair or replaced damaged tissue in the body. To help design new structures that enable cells to "shape up," researchers have come up with a way to measure, and more importantly, classify, the shapes cells tend to take in different environments. |
| Policies to reduce energy consumption in Germany missing targets, research shows Posted: 07 Feb 2014 05:38 AM PST New research has shown that policies to reduce energy consumption in homes are missing their targets. Germany's 2002 regulations were intended to create an 80% reduction by 2050 for energy used for home heating. According to the study, at the present rate reductions could achieve less than 25% by 2050. |
