Researchers map genetic ‘switches’ behind human brain evolution
FINDINGSUCLA researchers have developed the first map of gene regulation in human neurogenesis, the process by which neural stem cells turn into brain cells and the cerebral cortex expands in size. The scientists identified factors that govern the growth of our brains and, in some cases, set the stage for several brain disorders that appear later in life.BACKGROUNDThe human brain differs from that of mice and monkeys because of its large cerebral cortex. The organ ’s most highly developed part, the cerebral cortex is responsible for thinking, perceiving and sophisticated communication. Scientists are just beginning to un...

Voodoo Medicine: Time To Stop
The world's most celebrated athlete standing on the podium in Rio in honor of receiving yet another gold medal has something important in common with your lazy uncle throwing back a cold one in his Barcalounger. Yes, swimming powerhouse Michael Phelps, purple-spotted from cupping therapy, and your slovenly relative with a beer gut both share a bond -- a weakness in succumbing to the allure of voodoo medicine. Modern-day snake oil salesmen hawking quick cures and TV doctors peddling the latest diet miracle with blatantly ridiculous claims are everywhere on the tube, social media, the supermarket and old-fashioned billboards...

Autism-related genes linked to cognitive ability
Conclusion This study has found some small associations between common genetic variations linked to ASD and cognitive performance in the general population. Even where an association was found between genetic risk score and cognitive performance, the effect was very small. Less than 0.5% of the variability in people’s cognitive scores in the main study sample was explained by their ASD genetic risk score. The link between ASD genetic risk score and cognitive performance were only found in two of the three population samples assessed. This may be due to different age groups of participants, or to different cognitive tes...

Five 'mental disorders' may have genetic links
Conclusion This study suggests that autism, ADHD, clinical depression, bipolar disorder and schizophrenia may have common genetic risk factors. The five conditions examined in this study were selected on the basis of the availability of a large genetic data set. It is unclear at this stage whether other relatively common mental health conditions (such as anxiety disorder or obsessive compulsive disorder) are also affected by these genetic variations, or whether there is overlap with other conditions. Perhaps most importantly, these variations cannot on their own predict or explain the development of autism, ADHD, depressi...
