Roaming bits of DNA that can relocate and proliferate throughout the genome, called "jumping genes," may contribute to schizophrenia, a new study suggests. The study could help explain how genes and environment work together to produce schizophrenia and may even point to ways of lowering the risk of the disease.
Earth’s climate may warm considerably more than expected in response to a doubling of atmospheric carbon dioxide, a new study hints. The reason, the scientists say, is that simulations that now show only a moderate amount of warming don’t accurately depict the amount of cloud formation in the lower atmosphere. If true, warming of the planet will fall toward the high end of the range offered in every expert climate assessment of the past 3 decades.
For tobacco hornworms, bad breath might be the key to surviving the night. Scientists figured out that these caterpillars were keeping hungry spiders away by chewing on tobacco leaves. The caterpillars breathe out nicotine from the tobacco with every exhale, and their toxic breath sends wolf spiders fleeing.
