Numerous studies have shown that bigger is usually better. Now researchers have found that elderly adults who are more physically fit tend to have bigger hippocampi and better spatial memory than those who are less fit.The study, in the journal Hippocampus, shows that hippocampus size in physically fit adults accounts for about 40 percent of their advantage in spatial memory.Read more ….

February 9th, 2009 admin Image from Impact LabFrom E! Science News:LA JOLLA, CA—”Remember when…?” is how many a wistful trip down memory lane begins. But just how the brain keeps tabs on what happened and when is still a matter of speculation. A computational model developed by scientists at the Salk Institute for Biological Studies now suggests that newborn brain cells—generated by the thousands each day—add a time-related code, which is unique to memories formed around the same time.

December 26th, 2008 admin Scientists are getting closer to creating a bionic human, or at least a $6 million one. Today, we can replicate or restore more organs and various sundry body parts than ever before. From giving sight to the blind to creating a tongue more accurate than any human taste bud, gentlemen, we have the technology.
