Penn has received more than $155 million in research funding from the American Recovery and Reinvestment Act, awards that fund 288 studies in gene therapy, robotics, public education, neurological disorders, tobacco’s effect on health and more.
A major conclusion of the work is that for some organisms, possibly including humans, continued evolution will not translate into ever-increasing fitness.
The findings also indicate that the jump appears to occur between 1879 and 1915, a time of industrial change that may provide a direct link to human-induced climate change.
Scientists believes that the cognitive deficits caused by sleep deprivation, such as an inability to focus, learn or memorize, may be reversible by reducing the concentration of a specific enzyme that builds up in the hippocampus of the brain.
