| Startling decline in European birds: Majority of losses from most common species Posted: 02 Nov 2014 06:21 PM PST Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, according to a new study. However numbers of some less common birds have risen.       |
| Ultracold disappearing act: 'Matter waves' move through one another but never share space Posted: 02 Nov 2014 01:01 PM PST How can two clumps of matter pass through each other without sharing space? Physicists have documented a strange disappearing act by colliding Bose Einstein condensates that appear to keep their distance even as they pass through one another.  |
| Massive geographic change may have triggered explosion of animal life Posted: 01 Nov 2014 02:32 PM PDT A new analysis of geologic history may help solve the riddle of the "Cambrian explosion," the rapid diversification of animal life in the fossil record 530 million years ago that has puzzled scientists since the time of Charles Darwin. New research suggests a major tectonic event may be connected with the apparent burst of life that occurred 530 million years ago during the Cambrian explosion.  |
