| Archer fish hunt insects with water jet six times stronger than their muscular power Posted: 24 Oct 2012 02:53 PM PDT Archer fish knock their insect prey out of overhanging vegetation with a jet of water several times more powerful than the fish's muscles. New research now shows that the fish generate this power externally using water dynamics rather than with any specialized internal organs. The research provides the first explanation for how archer fish can generate such powerful jets to capture their prey. |

| Why 'singing' sand dunes hum certain notes Posted: 24 Oct 2012 11:02 AM PDT What does Elvis Presley have in common with a sand dune? No, it's not that people sometimes spot both in the vicinity of Las Vegas. Instead, some sand dunes, like The King, can sing. And new research looking for clues to how streams of sand can sing may explain why some dunes croon in more than one pitch at the same time. |
| Brain waves reveal video game aptitude Posted: 24 Oct 2012 10:34 AM PDT Scientists report that they can predict who will improve most on an unfamiliar video game by looking at their brain waves. |
| Bacterial wires explain enigmatic electric currents in the seabed Posted: 24 Oct 2012 10:33 AM PDT The enigma of electric currents in the seabed is solved. Scientists have discovered bacteria that function as living electrical cables. Each of the centimeter-long 'cable bacteria' contains a bundle of insulated wires leading an electric current from one end to the other. |
| Pica: Unearthing a hidden dietary behavior Posted: 24 Oct 2012 08:15 AM PDT A new study is showing that pica – and particularly geophagy, or the eating of soil or clay – is far more prevalent in Madagascar, one of the few areas of the world where it had gone unreported, than researchers previously thought. The research also suggests that the behavior may be more prevalent worldwide, particularly among men, than initially believed. |
| Native American ancestors' diet part of study and challenge Posted: 24 Oct 2012 06:30 AM PDT A diverse group of volunteers has committed one year to eating foods indigenous to the Great Lakes region in an effort to replicate the Native American diet prior to colonization. |
| A new take on the Midas touch: Changing the color of gold Posted: 24 Oct 2012 02:01 AM PDT Red gold, green gold - a ground-breaking initiative has found a way of changing the colour of the world's most iconic precious metal. Scientists have discovered that by embossing tiny raised or indented patterns onto the metal's surface, they can change the way it absorbs and reflects light – ensuring our eyes don't see it as 'golden' in colour at all. |
