Environmental Science & TechnologyWaste not, want not
By harnessing the efforts of billions of bacteria, researchers have engineered a bio-filtration system that produces hydrogen gas while cleaning wastewater – gas that could potentially fuel other machines. Up to 100 percent more efficient at producing hydrogen than similar bio-filtration systems, the new device has the added benefit of being able to digest human or animal waste, plant material or just about any organic matter.

ScienceWhale bones and farm soil: Sequencing biodiversity
Instead of sequencing the genome of one organism, why not sequence a drop of sea water, a gram of farm soil or even a sunken whale skeleton? Scientists at the EMBL in Heidelberg and their US collaborators have done just that, and the result is a new appreciation for the rich diversity of life that exists in the most unlikely places (Science, April 22, 2005).

BMC BiologyElephant seal pups suffer from ocean warming
Ocean warming has a negative impact on the condition of elephant seals, reveals a study published in the Open Access journal BMC Biology. High ocean temperatures observed from 1975 to the late 1990s are correlated with a 28% decrease in the weight of elephant seal pups. Elephant seals are shown to be sensitive to ocean temperature changes associated with both long-term 25-year cycles and short-term 3-4 year cycles such as those caused by El Niño.

Bulletin of the American Museum of Natural HistorySlime-mold beetles named for Bush, Cheney, Rumsfeld
George W. Bush, Dick Cheney and Donald Rumsfeld now each has a slime-mold beetle named in his honor. Two former Cornell University entomologists recently named 65 new species of slime-mold beetles; they are Quentin Wheeler and Kelly B. Miller, Cornell Ph.D. '01, whose monograph on the new species is published in the Bulletin of the American Museum of Natural History.

Proceedings of the National Academy of SciencesResearch shows overfishing of sharks key factor in coral reef decline
Scientists have developed an unprecedented model of a Caribbean marine ecosystem and details of its intricate predator-prey interactions. One of the most striking products of the study is a stark picture of human impacts on marine ecosystems and the consequences of targeted fishing. In the Caribbean, overfishing of sharks triggers a domino effect of changes in abundance that carries down to several fish species and contributes to the overall degradation of the reef ecosystem.

Butterfly migration could be largest known
Millions of painted lady butterflies that fluttered into California's Central Valley in the last week of March could be just the advance guard of one of the largest migrations of the species on record, said Arthur Shapiro, a professor and an expert on butterflies at UC Davis.

Research team recreates ancient underwater concrete technology
A University of Colorado at Boulder professor and his colleagues have taken a page from the writings of an ancient Roman architect and built an underwater concrete pier in the manner of those set in the Mediterranean Sea 2,000 years ago.

IUPS 35th Physiology Congress/Experimental Biology 2005Zinc supplementation improved mental performance of 7th-grade boys and girls
Seventh graders given 20 mg zinc, five days per week, for 10 to 12 weeks showed improvement in mental performance, responding more quickly and accurately on memory tasks and with more sustained attention, than classmates who received no additional zinc.

BioScienceEndangered Species Act provisions appear to benefit imperiled organisms
An analysis of the conservation status of 1095 species that have been protected under the US Endangered Species Act (ESA) indicates that those that have been given more protection under the act are more likely to be improving in status and less likely to be declining than species given less protection.
