| New vaccine-design approach targets viruses such as HIV Posted: 28 Mar 2013 01:14 PM PDT Scientists have unveiled a new technique for vaccine design that could be particularly useful against HIV and other fast-changing viruses.  |
| 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.  |
| Brain scans might predict future criminal behavior Posted: 28 Mar 2013 09:53 AM PDT A portable MRI was used to assess anterior cingulate cortex (ACC) activity in 96 adult male inmates who were then followed for up to four years after their release from prison. Those who re-offended were more likely to have lower ACC activity, indicating impulsivity and anti-social behavior.  |
| Brain's 'molecular memory switch' identified Posted: 28 Mar 2013 09:52 AM PDT Scientists have identified a key molecule responsible for triggering the chemical processes in our brain linked to our formation of memories. The findings reveal a new target for therapeutic interventions to reverse the devastating effects of memory loss.  |
| How diabetes drug delays aging in worms Posted: 28 Mar 2013 09:51 AM PDT A widely prescribed type 2 diabetes drug slows down the aging process by mimicking the effects of dieting, according to a study using worms to investigate how the drug works.  |
| 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.  |
