A study funded by the National Institutes of Health is unraveling the mystery of how blue light from residential and commercial lighting, electronic devices and outdoor lights can throw off-kilter the natural body clock of humans, plants and animals, leading to disease.
Exposure to blue light is on the increase, says chemist Brian Zoltowski, Southern Methodist University, Dallas, who leads the study. Continue reading
Instead of a gradual transition from dry to wetter, chemical analysis of ancient soils reveals there was an unexpected abrupt change. Samples came from the Morrison Formation, which sprawls 13 states and Canada and which has produced dinosaur discoveries for over 100 years. Continue reading
