| Artifacts shed light on social networks of the past Posted: 25 Mar 2013 03:40 PM PDT The advent of social networking sites like Facebook and Twitter have made us all more connected, but long-distance social networks existed long before the Internet. A new study led by an anthropologist provides new information on social networks in the pre-Hispanic Southwest in A.D. 1200-1450. Among the findings are that people were able to maintain surprisingly long distance relationships in a time when the only mode of transportation was walking.  |
| Scientists confirm first two-headed bull shark Posted: 25 Mar 2013 03:40 PM PDT Scientists have confirmed the discovery of the first-ever, two-headed bull shark.  |
| Clean electricity from bacteria? Researchers make breakthrough in race to create 'bio-batteries' Posted: 25 Mar 2013 03:39 PM PDT Scientists have made an important breakthrough in the quest to generate clean electricity from bacteria. New findings show that proteins on the surface of bacteria can produce an electric current by simply touching a mineral surface. The research shows that it is possible for bacteria to lie directly on the surface of a metal or mineral and transfer electrical charge through their cell membranes. This means that it is possible to 'tether' bacteria directly to electrodes – bringing scientists a step closer to creating efficient microbial fuel cells or 'bio-batteries.'  |
| Violins can mimic the human voice Posted: 25 Mar 2013 10:53 AM PDT For many years, some musical experts have wondered if the sound of the Stradivari and Guarneri violins might incorporate such elements of speech as vowels and consonants. A Texas A&M University researcher has now provided the first evidence that the Italian violin masters tried to impart specific vowel sounds to their violins.  |
| Posted: 25 Mar 2013 08:11 AM PDT Very much like a glass-blower, researchers have managed to shape the exit hole of a glass capillary and finely control its diameter between 200 nanometers and zero.  |
| New lung cancer study takes page from Google's playbook Posted: 25 Mar 2013 08:11 AM PDT A new study shows that the same sort of mathematical model that Google uses to predict which websites people want to visit may help researchers predict how lung cancer spreads through the human body.  |
