Winged dinosaur Archaeopteryx dressed for flight

The iconic, winged dinosaur Archaeopteryx was dressed for flight, an international team of researchers led by Brown University has concluded. The group identified the color of the raven-sized creature’s fossilized wing feather, determining it was black. The color and the structures that supplied the pigment suggest that Archaeopteryx’s feathers were rigid and durable, which would have helped it to fly. Results appear in Nature Communications.

Biochip measures glucose in saliva, not blood

Tripping the light fantastic: Each plasmonic interferometer – thousands of them per square millimeter – consists of a slit flanked by two grooves etched in a silver metal film. The schematic shows glucose molecules “dancing” on the sensor surface illuminated by light with different colors. Changes in light intensity transmitted through the slit of each plasmonic interferometer yield information about the concentration of glucose molecules in solution.
Engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological and environmental substances. Results are published in Nano Letters. (Distributed January 20, 2012)

Many high-risk Americans don’t get hepatitis B vaccine

Missed opportunities: A transmission electron microscope image shows particles of the hepatitis B virus. A vaccine has existed since 1982 but many people at high risk for getting the virus nevertheless are not innoculated.
A recently published study investigating hepatitis B vaccination rates in the United States found that more than half of adults at risk for hepatitis B virus remain unvaccinated. With many of these individuals making contact with the healthcare system, including HIV testing, this statistic reflects many missed opportunities to vaccinate this population.

Cosmetic chemical hinders brain development in tadpoles

Interrupted development: Even small concentrations — 1.5 parts per million — of a biocide used in cosmetics interrupted neurological development in tadpole brains. There is no evidence those  concentrations are harmful to humans.
A new study finds that low concentrations of the chemical methylisothiazolinone has subtle but measurable negative effects on the neural development of tadpoles. The chemical is found in some cosmetics, although the study does not provide any evidence that cosmetics are unsafe for humans. (Distributed January 10, 2012)
