Scientists unlock secret of emerging chikungunya virus's spread
December 13, 2007 03:54 PM - T. V. Padma, SciDevNet
University of Texas - A simple protein change in the chikungunya virus enables it to adapt to new mosquito hosts and spread to more regions, new research shows. Studies at the US-based University of Texas Medical Branch have found that a single amino acid change in the protein of the virus's outer shell helps it adapt to a new mosquito host, Aedes albopictus. The findings were published last in PLoS Pathogens.

Biocapture surfaces produced for study of brain chemistry
December 13, 2007 12:24 PM - Penn State
A research team at Penn State has developed a novel method for attaching small molecules, such as neurotransmitters, to surfaces, which then are used to capture large biomolecules. By varying the identity and spacing of the tethered molecules, researchers can make the technique applicable to a wide range of bait molecules including drugs, chemical warfare agents, and environmental pollutants. Ultimately, the researchers also hope to identify synthetic biomolecules that recognize neurotransmitters so that they can fabricate extremely small biosensors to study neurotransmission in the living brain.

Chemicals used as fire retardants could be harmful
December 12, 2007 05:02 PM - UC Riverside, Newswire
Riverside, California - Polybrominated diphenyl ethers (PBDEs), chemicals used as fire retardants, can be found in numerous items in the home, such as the television, computer, toaster and the sofa. Now, as reported in a news story days ago, they are being found in alarming concentrations, in human blood and breast milk – a potentially major concern for human health.
