"Because the participants in this study are telling us they have never been previously diagnosed with pesticide poisoning or medically treated for any exposure to any pesticide, we are led to conclude that their symptoms are rel...

Cricket's finicky mating behavior boosts biodiversity

...ervous systems and brains have preferences and can make choices," says Tamra Mendelson, an evolutionary biologist at Lehigh. "Changes in these preferences and choices appear to drive speciation. "That raises the question: Can something seemingly so individual as a choice have macro-evolutionary consequen...

Scientists discuss improved biopesticides for locust control in West Africa

... applicable to many other biopesticides and should make them more effective as well,." Agblevor said Local officials are calling the infestation in West Africa the worst in 18 years. The pests invaded the region last summer, affecting millions of acres of farmland. The locusts are in recession now becaus...

Programmable cells: Engineer turns bacteria into living computers

The UCLA Institute for Stem Cell Biology and Medicine will focus its embryonic and adult stem cell research in thre...

Wisconsin researchers identify sleep gene

...genetic forces push hard against this phenotype to make it ineffective," Cirelli says. "Being a short sleeper is probably not a good thing. We know that the mns mutation affects mortality, but we're not sure how." In earlier studies, Tononi's team discovered that fruit flies do, in fact, sleep. "The mor...

DuPont's first biologically derived polymer receives global recognition

...ng. DuPont scientists recently developed a way to make Bio-PDOTM, the key Sorona® ingredient, from corn using a new biological process that requires over 40 percent less total energy than the traditional petrochemical feedstock. It will be commercially available in 2006. In 2003, the U.S. Environmenta...
