Although Bush's article in Science noted "key uncertainties remain concerning the underlying causes and nature of climate change," it stated that his agenda aims to reduce greenhouse gas intensity by 18% over the next decade through next-generation hydrogen and clean coal technologies. When...Study: Emission of smog ingredients from trees is increasing rapidly
...aused by the changes in tree-produced VOCs. Purves noted that interactions between VOCs, NOx and ozone are complex -- some may actually lower pollution -- so it would be premature to base environmental policy on studies of VOCs alone. Purves, a postdoctoral fellow, wrote the article in collaboration with S...16 APS exercise research highlights, from reduced flu mortality to proteomics & obesity
...Missouri-Columbia, College of Veterinary Medicine, noted that in addition to the 12 symposia of invited speakers, ample time each day has been set aside for discussing the over 380 presentations with the authors.

Vieites noted that this unusual mating strategy is a good way for the frog population to ensure that as many genes as possible are passed on to succeeding generations, particularly when there are far more males than females.

Figuring out exactly how the complex sugars work will take more research, but developing such understanding, she said, could ...IBD (Crohn's/ulcerative colitis) conference adds 18 speakers; APS meeting starts Thursday

The hospitalization rates for Hispanics and Asians were lower at the HMO. ...New genetic hypothesis for the cause of autism

They also noted the difference in the effects of a gene depending on which parent transmits it, which strongly suggests an epigenetic effect called genomic imprinting. The authors do not argue that their data prove the components of the oligogenic hypothesis. They ...Fossils reveal direct link between global warming and genetic diversity in wildlife

She noted that the methods developed for the study offer wildlife biologists a unique approach to understanding the long-range effects of climate change on genetics.
