Scientists determine fish are magnetic
In a study recently published in Current Biology, scientists from the University of Oldenberg in Germany have determined that fish use magnetic fields to find their way back to their birthplace. Consistent experiments show that the larvae of Doederlein’s cardinalfish, Ostorhinchus doederleini, will swim south south-east after being thrust into the ocean’s currents. However, when scientists applied a magnetic field to tanks of newly hatched larvae, and then adjusted it by 180-degrees, the fish adjusted their direction every time.
National Geographic and NPS explores inside the well preserved USS Arizona
Archaeologists from the National Park Service and photographers from National Geographic have just completed a 10-day expedition to document interior portions of the U.S.S. Arizona that have previously not been seen since the ships’ sinking in 1941. The 608-foot long battleship sits in 40-feet of water and is one of the most well studied shipwrecks, but sections within the ship have been unreachable until now.
