Karpinski and Duberstein's study isn't the first to associate Facebook with diminished mental abilities. In February, Oxford University neuroscientist Susan Greenfield cautioned Britain's House of Lords that social networks like Facebook and Bebo were "infantilizing the brain into the state of small children" by shortening the attention span and providing constant instant gratification. And in his new book, iBrain: Surviving the Technological Alteration of the Modern Mind, UCLA neuroscientist Gary Small warns of a decreased ability among devotees of social networks and other modern technology to read real-life facial expressions and understand the emotional context...
...fuel that cells and tissues like muscle need to keep working. But exercise experts say that despite what you may think, energy drinks have no effect at all on your tired muscles. Instead, when your energy is petering out, a swig of an energy drink works on the brain to keep you inspired and motivated to push on. (Read "China Says 'Keep Out' to Coca-Cola...
...Researchers at the University of Birmingham and Manchester Metropolitan University report in the Journal of Physiology that sugary energy drinks activate reward and pleasure regions in the brain, a boost that can translate to better performance - and one that does not occur with other artificially sweetened beverages. In the study, volunteers who got sugary energy drinks were able to complete a physical-training session 2% faster than those who got artificially sweetened drinks, and improved their mean power output as well...
...them, then create replacement bodies. First they will produce lineages of stem cells without destroying the embryo, which will make genetic therapy ethically acceptable, and then reproductive cloning. Finally they will manufacture the human being like a made-to-measure artifact, in an artificial uterus, which will allow the brain to further develop with characteristics chosen in advance. The human being will thus have become a commercial object...
...uncontrollably, they need to induce the formation of new blood vessels to bring them oxygen and nutrients—a process known as angiogenesis. A team of researchers at Massachusetts General Hospital has discovered that the main effects of an angiogenesis inhibitor in treating glioblastoma, a severe kind of brain tumor, stem from the reduction of brain swelling, rather than any effect on tumor growth. In these tumors, blood vessels can be leaky, which causes swelling in the brain known as edema. This, in turn, can cause drowsiness, loss of consciousness, and brain damage. A Phase II clinical trial with...
