| What triggers a mass extinction? Habitat loss and tropical cooling were once to blame Posted: 10 Apr 2012 11:59 AM PDT The second-largest mass extinction in Earth's history coincided with a short but intense ice age. Although it has long been agreed that the so-called Late Ordovician mass extinction was related to climate change, exactly how the change produced the extinction has not been known. Now, scientists have determined that the majority of extinctions were caused by habitat loss due to falling sea levels and cooling of the tropical oceans.  |
| Brain-injury data used to map intelligence in the brain Posted: 10 Apr 2012 10:08 AM PDT Scientists report that they have mapped the physical architecture of intelligence in the brain. This is one of the largest and most comprehensive analyses so far of the brain structures vital to general intelligence and to specific aspects of intellectual functioning, such as verbal comprehension and working memory.  |
| Personality, habits of thought and gender influence how we remember Posted: 10 Apr 2012 10:08 AM PDT We all have them -- positive memories of personal events that are a delight to recall, and painful recollections that we would rather forget. A new study reveals that what we do with our emotional memories and how they affect us has a lot to do with our gender, personality and the methods we use (often without awareness) to regulate our feelings.  |
| U.S. records warmest March; more than 15,000 warm temperature records broken Posted: 10 Apr 2012 08:40 AM PDT Record and near-record breaking temperatures dominated the eastern two-thirds of the United States and contributed to the warmest March on record for the contiguous United States, a record that dates back to 1895. More than 15,000 warm temperature records were broken during the month.  |
| Eggs of enigmatic dinosaur in Patagonia discovered Posted: 10 Apr 2012 07:20 AM PDT An Argentine-Swedish research team has reported a 70-million-year-old pocket of fossilized bones and unique eggs of an enigmatic birdlike dinosaur in Patagonia.  |
| Born nice? Peoples' niceness may reside in their genes, study finds Posted: 10 Apr 2012 06:31 AM PDT It turns out that the milk of human kindness is evoked by something besides mom's good example. Research by psychologists has found that at least part of the reason some people are kind and generous is that their genes nudge them toward it.  |
| Climate change helps, then quickly stunts plant growth, decade-long study shows Posted: 09 Apr 2012 07:32 AM PDT Global warming may initially make the grass greener, but not for long, according to new research. A new study shows that plants may thrive in the early stages of a warming environment but begin to deteriorate quickly.  |
