Examine of fruit fly ties sensory neurons to regulation of sleep-wake cycle — ScienceDaily

Winter could also be behind us, however do you keep in mind the problem of waking up on these chilly, darkish days? Temperature impacts the habits of practically all dwelling creatures, however there’s nonetheless a lot to study in regards to the hyperlink between sensory neurons and neurons controlling the sleep-wake cycle. Northwestern College neurobiologists have uncovered a clue to what’s behind this habits. In a examine of the fruit fly, the researchers have recognized a “thermometer” circuit that relays details about exterior chilly temperature from the fly antenna to…

After they encounter nutrient oases within the marine desert, marine micro organism launch a gasoline concerned in local weather regulation — ScienceDaily

A brand new research exhibits that “hotspots” of vitamins surrounding phytoplankton — that are tiny marine algae producing roughly half of the oxygen we breathe day-after-day — play an outsized position within the launch of a gasoline concerned in cloud formation and local weather regulation. The brand new analysis quantifies the best way particular marine micro organism course of a key chemical referred to as dimethylsulfoniopropionate (DMSP), which is produced in huge quantities by phytoplankton. This chemical performs a pivotal position in the best way sulfur and carbon get consumed…
