| Posted: 29 Apr 2013 01:49 PM PDT Scientists have found that liquid crystalline silicone stiffens significantly when compressed repeatedly for hours on end. The discovery may lead to new strategies for self-healing materials or biocompatible materials that mimic human tissues.  |
| Researcher reveals new way to safeguard forensic dna samples against contamination Posted: 29 Apr 2013 01:47 PM PDT DNA evidence is invisible and remarkably easy to transfer, making it possible for a sample to be spilled or even planted on a piece of evidence. Scientists have now developed a solution that permanently marks DNA samples to prevent contamination. Hampikian has used nullomers, the smallest DNA sequences that are absent from nature, to create the DNA bar code.  |
| First snapshot of organisms eating each other: Feast clue to smell of ancient Earth Posted: 29 Apr 2013 12:41 PM PDT Tiny 1,900-million-year-old fossils from rocks around Lake Superior, Canada, give the first ever snapshot of organisms eating each other and suggest what the ancient Earth would have smelled like.  |
| Cicadas get a jump on cleaning Posted: 29 Apr 2013 12:41 PM PDT As cicadas on the East Coast begin emerging from their 17-year slumber, a spritz of dew drops is all they need to keep their wings fresh and clean.  |
| Singing humpback whales tracked on Northwest Atlantic feeding ground Posted: 29 Apr 2013 10:36 AM PDT Male humpback whales sing complex songs in tropical waters during the winter breeding season, but they also sing at higher latitudes at other times of the year. NOAA researchers have provided the first detailed description linking humpback whale movements to acoustic behavior on a feeding ground in the Northwest Atlantic.  |
| Posted: 29 Apr 2013 10:05 AM PDT Scientists have developed an innovative method for diagnosing schizophrenia by collecting neural tissues from the nose. The finding could lead to early detection of the disease, giving rise to vastly improved treatment overall.  |
| How Would You Like Your Assistant -- Human or Robotic? Posted: 29 Apr 2013 09:55 AM PDT More than half of healthcare providers interviewed for a new study said that if they were offered an assistant, they preferred it to be a robotic helper rather than a human. However, they don't want robots to help with everything.  |
| Researchers design nanometer-scale material that can speed up, squeeze light Posted: 29 Apr 2013 06:46 AM PDT In a process one researcher compares to squeezing an elephant through a pinhole, researchers have designed a way to engineer atoms capable of funneling light through ultra-small channels.  |
