Science On Top

For the first time, a salty subsurface ocean on Jupiter's largest moon Ganymede has been detected through the use of auroras. The idea of a subsurface ocean isn't new, but auroras have never before been used as a detection mechanism. In an elegant experiment, scientists at the Max Planck Institute for Chemical Ecology have found that bacteria can share nutrients between each other through tiny feeding tubes. Researchers in France have modified memories in sleeping mice. My electrically stimulating parts of the brain they were able to associate certain locations with rewards. A team of scientists at the Weizmann Institute of Science in Israel were testing the theory that people sniff their hands after handshakes. They secretly filmed 153 volunteers and discovered that handshakes could be responsible for transmitting chemical biosignals between people. There are 17 regions on Comet 67P that have material that appears to be moving. And now scientists may have figured out how these "wind tails" may be occurring.
