Researchers at the University of Minnesota genetically altered mice so they developed a brain similar to a person with Alzheimer's disease. When the mice were given special genes, their memory loss not only stopped, they regained memory. Researchers say this new information suggests drugs could be created to reverse the effects of memory loss even in patients who have lost some brain tissue.
Asthma and allergies could help protect you from a common type of brain cancer. Researchers at the Ohio State University found people who have genes that double the risk for asthma., were 40% less likely to have a brain tumor. They believe the genes that increase the risk for asthma and allergies may actually reduce inflammation in the brain, helping to protect it from cancer.
Finally, from the University of Edinburgh proof that being smart doesn't necessarily make you happy. In one of the longest running studies ever done on the subject, hundreds of people in Scotland were given intelligence tests at age 11, and then again at age 79. Turns out a high IQ had nothing to do with their happiness or satisfaction with life.
