Learning Changes Brain Cell Connectivity

March 1, 2014May 31, 2014 Wa'd Abuzurayk

A new discovery has been achieved in the world of neurology. Scientists have made progress in better understanding what happens inside our brains when we learn or remember information. According to the University of British Columbia research team, molecular changes are observed in the brain when one learns or remembers. Such changes occur in the brain’s chemistry as fatty acids attach to delta-catenin (a protein important for normal cognitive development- Wikipedia) upon learning new things, which ultimately alters brain cell connectivity coupled with learning and memory. The study was conducted…

Ghost Knifefish Inspired Autonomous Underwater Vehicle: Biomimicry

In an attempt to design an underwater vehicle that can go into the depths of ocean, which are not, accessible or not safe for humans to dive in, scientists are studying the Ghost knifefish method of locomotion. The fish are known to hunt in the murky water of the Amazon basin with precision and to sense the environment, rely on the current that they pass through the water and whirl their long fin for smooth motion to move both horizontally (forward and backward) as well as vertically.
