| Genetic study demonstrates Israel's wild boars originated in Europe Posted: 04 Nov 2013 12:27 PM PST Scientists had no reason to suspect Israeli wild boars were any different than their brothers and sisters roaming the Middle East. Now, a researcher demonstrates that, unlike the Near Eastern wild boars in surrounding countries, Israel's wild boars originated in Europe, brought to Israel starting almost 3,000 years ago by the Philistines and other seafaring raiders. |
| Posted: 04 Nov 2013 12:27 PM PST Astronomers analyzed all four years of Kepler data in search of Earth-size planets in the habitable zones of sun-like stars, and then rigorously tested how many planets they may have missed. Based on this analysis, they estimate that 22 percent of stars like the sun have potentially habitable Earth-size planets, though not all may be rocky or have liquid water, a presumed prerequisite for life. |
| Fossil of largest known platypus discovered in Australia Posted: 04 Nov 2013 12:27 PM PST Until recently, the fossil record indicated that the platypus lineage was unique, with only one species inhabiting the Earth at any one time. This picture has changed with the spectacular find of a new, giant species of extinct platypus that was a side-branch of the platypus family tree. |
| Posted: 04 Nov 2013 12:26 PM PST An astrophysicist was part of a team of researchers that discovered the first examples of black holes in globular star clusters in our own galaxy, upsetting 40 years of theories against their possible existence. |
| Brain aging is conclusively linked to genes Posted: 04 Nov 2013 12:26 PM PST For the first time in a large study sample, the decline in brain function in normal aging is conclusively shown to be influenced by genes, say American researchers. |
| Fishy behavior solves an animal locomotion mystery Posted: 04 Nov 2013 12:25 PM PST The puzzling, apparently wasteful habit of some animals to exert force in the direction opposite of where they want to go actually has an important purpose: to increase both stability and maneuverability. |
| Civilizations rise and fall on the quality of their soil Posted: 04 Nov 2013 12:52 AM PST Great civilizations have fallen because they failed to prevent the degradation of the soils on which they were founded. The modern world could suffer the same fate. |
