  嘉兴人才市场Top stories- Saturn’s helium ‘rain,’ autism and antidepressants, and U.S. science’s budget boostTop stories: Saturn’s helium ‘rain,’ autism and antidepressants, and U.S. science’s budget boost Budget agreement boosts U.S. scienceBetter late than never for the federal budget. More than 2 months after the fiscal year officially began, the U.S. Congress approved an overall 2016 spending bill by an overwhelming margin on 18 December. Find out which research agencies got what (and what they’re planning on doing with their shares) by reading ScienceInsider’s complete coverage.What the mites on your face say about where you came fromRight now, deep in your hair follicles and sweat glands, tiny mites are feeding on dead skin cells, mating, and laying eggs. The microscopic arthropods live on virtually all mammals—especially their faces—and cause no harm under most circumstances. Now, a new study shows that people of different ancestry carry different subgroups of the bugs, and that the mites’ distribution throughout the global population may even reflect how our species has migrated and evolved over the course of history.Physicists find new evidence for helium ‘rain’ on SaturnUsing one of the world’s most powerful lasers, physicists have found experimental evidence for Saturn’s helium “rain,” a phenomenon in which liquid hydrogen and helium mixed together in the planet’s atmosphere separate, resulting in showers of liquid helium. The results show the range of blistering temperatures and crushing pressures at which this can takes place. But they also suggest that helium rain could also fall on Jupiter, where such behavior was almost completely unexpected.Reality check: Taking antidepressants while pregnant unlikely to double autism risk in kidsNo one really knows why rates of autism have roughly doubled over the past 10 years. Now, a new study claims antidepressant use during pregnancy can increase a child’s risk of developing autism. Reporter Emily Underwood delves into the research, which has been raising eyebrows in the psychiatry and neuroscience communities.Natural lipstick helps male monkeys get the girlAs the Rolling Stones, Revlon, and Angelina Jolie can attest, not many body parts are more sexualized than the lips. A new study suggests that black-and-white snub-nosed monkeys agree: Females seem to prefer red lips when choosing a mate, similar to how a female peacock chooses the male with the most elaborate tail. And when mating season comes around, alpha males’ lips turn several shades darker, whereas bachelor males’ lips become paler.
