| Females shut down male-male sperm competition in leafcutter ants Thu, 18 Mar 2010 00:00:00 EDT |
(Smithsonian Tropical Research Institute) Danish researchers who have studied ants at the Smithsonian Tropical Research Institute in Panama since 1992 discovered that in both ant and bee species in which queens have multiple mates, a male's seminal fluid favors the survival of its own sperm over the other males' sperm. However, once sperm has been stored, leafcutter ant queens neutralize male-male sperm competition with glandular secretions in their sperm-storage organ. |

| Giant sequoias yield longest fire history from tree rings Thu, 18 Mar 2010 00:00:00 EDT |
(University of Arizona) A 3,000-year record from 52 of the world's oldest trees shows that California's western Sierra Nevada was droughty and often fiery from 800 to 1300, according to new research. Scientists reconstructed the region's history of fire by dating fire scars on ancient giant sequoia trees, Sequoiadendron giganteum, in the Giant Forest of Sequoia National Park. Individual giant sequoias can live more than 3,000 years and are considered the world's largest trees by volume. |

Tupper Research and Conference Center in Panama City, Panama, from March 22-24, 2010. |
| Prescribed burns may help reduce US carbon footprint Wed, 17 Mar 2010 00:00:00 EDT |
(National Science Foundation) The use of prescribed burns to manage western forests may help the United States reduce its carbon footprint.Results of a new study find that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size. |
| Genetics Society of America's 51st Annual Drosophila Research Conference Wed, 17 Mar 2010 00:00:00 EDT |
(Genetics Society of America) Representatives of the media are invited to attend the 51st Annual Drosophila Research Conference in Washington, D.C., April 7-11, 2010, sponsored by the Genetics Society of America. More than 1600 basic research scientists who study genetic models in Drosophila (fruit flies) are expected to attend. |

(National Institute of Standards and Technology (NIST)) Stacked sheets of graphene may be a promising material for capturing and storing hydrogen for future fuel-cell systems according to recent research at NIST and the University of Pennsylvania. |
| Tomas moving away from Fiji Islands after causing damages Wed, 17 Mar 2010 00:00:00 EDT |
(NASA/Goddard Space Flight Center) Cyclone Tomas hit the north and east areas of Fiji as a Category 4 cyclone on the Saffir-Simpson Scale, and has now moved south of them. NASA's Tropical Rainfall Measuring Mission satellite captured an image of the heavy rains that were falling in Tomas during his swath of destruction in the Fiji Islands. |

| Frogs, foam and fuel: University of Cincinnati researchers convert solar energy to sugars Tue, 16 Mar 2010 00:00:00 EDT |
(University of Cincinnati) In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant -- like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers at the University of Cincinnati are doing something about that. |
