| How sea otters can reduce CO2 in the atmosphere: Appetite for sea urchins allows kelp to thrive Posted: 07 Sep 2012 01:14 PM PDT A new study suggest that a thriving sea otter population that keeps sea urchins in check will in turn allow kelp forests to prosper and help reverse a principal cause of global warming. |
| Precautions for tick-borne disease extend 'beyond Lyme' Posted: 07 Sep 2012 11:23 AM PDT This year's mild winter and early spring were a bonanza for tick populations in the eastern United States. Reports of tick-borne disease rose fast. While Lyme disease is the most common tick-borne disease in the Northeast and Upper Midwest, new research results emphasize that it is not the greatest cause for concern in most Southeastern states. |
| First look at structure of vital molecule Posted: 07 Sep 2012 10:16 AM PDT Molybdenum is an essential metal required in all living beings from bacteria to plants to humans. But as vital as this metal is, no one understood the importance of the structure of a vital molecule that interacts with molybdenum until now. |
| Posted: 07 Sep 2012 10:16 AM PDT A team of researchers in Arizona has found that warming resulting from megapolitan expansion is seasonally dependent, with greatest warming occurring during summer and least during winter. Among the most practical ways to combat urbanization-induced warming -- the painting of building's roofs white -- was found to disrupt regional hydroclimate, highlighting the need for evaluation of tradeoffs associated with combating urban heat islands. |
| Ancient, humble critter proves: Newer isn’t always better Posted: 07 Sep 2012 08:16 AM PDT Tiny sea creatures called rhabdopleurids reside on the ocean floor, building homes of collagen on the shells of dead clams. Rhabdopleurid colonies are small, and the critters are by no means the dominant animals in their ecosystem. But they have lived this way -- and survived -- for more than 500 million years. And in doing so, they have outlasted more elaborate species that also descended from a common ancestor, according to a new study. |
| Archaeologists uncover 'lost garden' in quest for Richard III Posted: 07 Sep 2012 05:20 AM PDT Archaeologists from the UK who are leading the search for the lost grave of King Richard III announced that they have made a new advance in their quest. They have uncovered evidence of the lost garden of Robert Herrick -- where, historically, it is recorded there was a memorial to Richard III. Now the "time tomb team" as they have become to be known has discovered paving stones which they believe belong to the garden. |
| The birdy smell of a compatible partner Posted: 07 Sep 2012 04:23 AM PDT New evidence shows that birds may choose their mate with the help of smell. They prefer a dissimilar mate because this gives their young a more efficient immune system. |
