| Early spring means more bat girls Posted: 04 May 2012 02:20 PM PDT A study on bats suggests that bats produce twice as many female babies as male ones in years when spring comes early. |
| Largest known crocodile could swallow a human Posted: 04 May 2012 02:19 PM PDT A crocodile large enough to swallow humans once lived in East Africa, according to new research. It may have exceeded 27 feet in length. By comparison, the largest recorded Nile crocodile was less than 21 feet, and most are much smaller. |
| Why Saturday’s 'supermoon' will be beautiful, but not super Posted: 04 May 2012 10:57 AM PDT Yes, it will be marginally brighter and larger, but Saturday's so-called "supermoon" is not going to be noticeably different from the full moon of the month before or after. An astronomer explains that a "supermoon" typically happens once a year, when the moon's elliptical orbit comes closest to Earth during a full moon. But the nickname makes it sound like a much bigger deal than it actually is. |
| Less is more, for female cowbirds: Findings contradict sexual selection theory Posted: 04 May 2012 08:05 AM PDT More modest male displays attract the females when it comes to brown-headed cowbirds, contrary to sexual selection theory, according to new research. While sexual selection theory predicts that females should find more flamboyant displays the most sexually attractive, the opposite holds true for brown-headed cowbirds, a small songbird common in North America. |
| What is your dog thinking? Brain scans unleash canine secrets Posted: 04 May 2012 08:05 AM PDT Researchers have developed a new methodology to scan the brains of alert dogs and explore the minds of the oldest domesticated species. The technique uses harmless functional magnetic resonance imaging, the same tool that is unlocking secrets of the human brain. The brain images of a fully awake, unrestrained dog, thought to be the first, opens up a door for understanding canine cognition and inter-species communication. |
