| Posted: 28 Mar 2013 11:24 AM PDT Less-than-perfect sheets of atom-thick graphene show unexpected weakness, according to researchers.  |
| Biological transistor enables computing within living cells Posted: 28 Mar 2013 11:24 AM PDT Bioengineers have taken computing beyond mechanics and electronics into the living realm of biology. Scientists have used a biological transistor made from genetic material -- DNA and RNA -- in place of gears or electrons. The team calls its biological transistor the "transcriptor."  |
| Swarming robots could be the servants of the future Posted: 28 Mar 2013 09:53 AM PDT Swarms of robots acting together to carry out jobs could provide new opportunities for humans to harness the power of machines.  |
| Sprial galaxy: Hidden depths of Messier 77 revealed Posted: 28 Mar 2013 09:51 AM PDT The NASA/ESA Hubble Space Telescope has captured this vivid image of spiral galaxy Messier 77, one of the most famous and well-studied galaxies in the sky. The patches of red across this image highlight pockets of star formation along the pinwheeling arms, with dark dust lanes stretching across the galaxy's energetic center.  |
| Opposites attract: How cells and cell fragments move in electric fields Posted: 28 Mar 2013 09:51 AM PDT Like tiny crawling compass needles, whole living cells and cell fragments orient and move in response to electric fields -- but in opposite directions, scientists have found. Their results could ultimately lead to new ways to heal wounds and deliver stem cell therapies.  |
| Large robotic jellyfish could one day patrol oceans Posted: 28 Mar 2013 09:48 AM PDT Researchers have unveiled Cyro, a life-like, autonomous robotic jellyfish the size and weight of a grown man, 5 foot 7 inches in length and weighing 170 pounds.  |
| Cold cities less sustainable than warm cities, research suggests Posted: 28 Mar 2013 04:57 AM PDT Living in colder climates in the US is more energy demanding than living in warmer climates. Scientists have calculated that climate control in the coldest large metropolitan area in the country – Minneapolis – is about three-and-a-half times more energy demanding than in the warmest large metropolitan area – Miami.  |
| Scientists propose revolutionary laser system to produce the next LHC Posted: 28 Mar 2013 04:57 AM PDT An international team of physicists has proposed a revolutionary laser system, inspired by the telecommunications technology, to produce the next generation of particle accelerators, such as the Large Hadron Collider.  |
