Researchers at the University of Pennsylvania School of Medicine are closer to understanding how the sense of taste develops. They have pinpointed a molecular pathway that regulates the development of taste buds. Using genetically engineered mice, they discovered that a signaling pathway activated by small proteins called Wnts is required for initiating taste-bud formation. They have also determined that Wnt proteins are required for hooking up the wiring of taste signals to the brain.
The largest, most comprehensive survey of public perceptions of nanotechnology products finds US consumers are willing to use specific nano-containing products — even if there are health and safety risks — when the potential benefits are high. The study also finds US consumers rate nanotechnology as less risky than everyday technologies like herbicides, chemical disinfectants, handguns and food preservatives. The findings appear in December’s issue of Nature Nanotechnology.
Geology topics of interest include: Two New Zealand supervolcanoes that erupted only days or weeks apart; remarkably detailed K-T boundary evidence from the tropical Atlantic’s Demerara Rise supporting a single impact event; and human impact on continental erosion and sedimentation.
Research by scientists at the ARC Centre of Excellence for Coral Reef Studies and James Cook University has warned that coral reef shark populations on the Great Barrier Reef are in the midst of a catastrophic collapse.
A report by Consumer Reports in the US indicates that eighty three percent of chicken sold in US grocery stores may contain bacteria that cause foodborne illnesses, either campylobacter or salmonella bacteria or both. The US Department of Agriculture (USDA), however, says the study was flawed.
