| Sticky paper offers cheap, easy solution for paper-based diagnostics Posted: 02 Oct 2012 03:30 PM PDT Global health researchers are working on cheap systems like a home-based pregnancy test that might work for malaria, diabetes or other diseases. A new chemical technique makes medically interesting molecules stick to regular paper -- a possible route to building such paper-based diagnostics from paper you could buy at an office-supply store.  |
| Acoustic cell-sorting chip may lead to cell phone-sized medical labs Posted: 02 Oct 2012 01:19 PM PDT A technique that uses acoustic waves to sort cells on a chip may create miniature medical analytic devices that could make Star Trek's tricorder seem a bit bulky in comparison, according to experts.  |
| One glue, two functions: Spider webs stick to the ground and elevated surfaces differently Posted: 02 Oct 2012 12:42 PM PDT Polymer scientists and biologists have discovered that a house spider -- in order to more efficiently capture different types of prey -- performs an uncommon feat. It tailors one glue to demonstrate two adhesive strengths: firm and weak.  |
| The science behind those eye-popping northern lights Posted: 02 Oct 2012 12:41 PM PDT Stormy weather on the sun drives the glistening aurorae in our clear night skies.  |
| Superman-strength bacteria produce 24-karat gold Posted: 02 Oct 2012 12:00 PM PDT At a time when the value of gold has reached an all-time high, researchers have discovered a bacterium's ability to withstand incredible amounts of toxicity is key to creating 24-karat gold.  |
| Posted: 02 Oct 2012 11:57 AM PDT Researchers are building transparent, two-terminal, three-dimensional computer memories on flexible sheets that show promise for making transparent electronics and sophisticated heads-up displays.  |
| 'Let’s-go rumble': For elephants, deciding to leave the watering hole demands conversation Posted: 02 Oct 2012 11:57 AM PDT In the wilds of Africa, when it's time for a family of elephants gathered at a watering hole to leave, the matriarch of the group gives the "let's-go rumble." This behavior shows how this cognitively advanced species uses well-coordinated "conversations" to initiate cooperation within the group.  |
| Switching cause and effect in quantum world? A causes B causes A Posted: 02 Oct 2012 11:54 AM PDT A deeply rooted concept in everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. Physicists have now shown that in quantum mechanics it is possible to conceive situations in which a single event can be both, a cause and an effect of another one.  |
| Egyptian toe tests show they're likely to be the world's oldest prosthetics Posted: 02 Oct 2012 07:15 AM PDT The results of scientific tests using replicas of two ancient Egyptian artificial toes, including one that was found on the foot of a mummy, suggest that they're likely to be the world's first prosthetic body parts.  |
