Dec 10, 2013 — All medications come with risks, and one of the risks with popular heartburn medicines seems to be that they interfere with the absorption of vitamin B-12. That can cause troubling symptoms, from anemia and depression to dementia.
Dec 2, 2013 — Is the idea that the left hemisphere of the brain is more logical and the right more intuitive a scientific fact or a cultural fiction? Commentator Tania Lombrozo turns to an expert for answers.
Nov 18, 2013 — Recent findings challenge the idea that people are more likely to buy into research that features pretty pictures of the brain. Commentator Tania Lombrozo says our responses to neuroimages may just reflect our conflicting instincts about reductionism and the limits of science.
Nov 12, 2013 — Criminal lawyers increasingly turn to brain science to explain their clients' actions. It's a tactic that's kept defendants out of jail. But neuroscientists say scans can be easily misused or misinterpreted. Now judges must decide whether the evolving science is being used in a sensible way.
Nov 11, 2013 — Physical exercise can ease depression, slow age-related memory loss and prevent Parkinson-like symptoms, researchers reported at a meeting in San Diego. The findings suggest that people may be making a mistake if they're relying on crossword puzzles and brain-training games for mental wellness.
Oct 28, 2013 — Humans and other primates have really good vision. One scientist thinks that ability evolved in part to help monkeys and humans quickly recognize venomous snakes. When monkeys see photos of snakes, neurons in a specific part of the brain light up. The neurons respond to photos of the reptiles more than to monkey faces.
Oct 7, 2013 — The Nobel Prize in Physiology or Medicine 2013 goes to three scientists for discovering how cells secrete hormones and neurotransmitters. The research provided sweeping insights into how the brain transmits signals, the immune system attacks pathogens and insulin gets into the bloodstream.
Oct 2, 2013 — Scientists have figured out how DEET repels mosquitoes. The finding has led the researchers to candidate repellents that are safer and cheaper than DEET and may provide new weapons against mosquito-borne scourges, such as malaria and dengue fever.
Sep 23, 2013 — It used to be that neuroscientists thought smart people were all alike. But now they think that some very smart people retain the ability to learn rapidly, like a child, well into adolescence. That means they have a longer period of time to learn from their environment — and maybe learn Chinese.
Sep 4, 2013 — The aging brain may be more flexible than we thought, a study of older adults now suggests. After playing a racing car video game an hour a day, thrice weekly for a month, adults age 60 and over were better at multitasking than untrained 20-year-olds.
