A recent research from the National Institutes of Health, US, finds that regular running grows brain connections and therefore may boost cognitive health.
For the study, a team of researchers divided mice into two groups, having a sedentary group and an active group. They routinely analyzed brain tissue of the active group and the sedentary group. Having analyzed the received data, the scientists concluded that brain cells produced under running conditions were not only quantitatively but also qualitatively different.
Experts believe that the findings of this study should be a red flag for those who don’t like going to a gym, as while they may wait until the scales start to creep up, they should consider the silent benefits of a workout.
A new study, published in the journal Neuro Toxicology, finds that children exposed to air manganese may have lower IQ scores.
The study was led by Dr. Erin Haynes, an associate professor in the Department of Environmental Health at the University of Cincinnati College of Medicine in Ohio. A team of researchers analyzed blood and hair samples of 106 children in East Liverpool, Ohio, aged between 7 and 9 between March 2013 and June 2014.
The analysis has shown that hair manganese levels correlated negatively with full-scale IQ scores, as well as with processing speed and working memory.
Dr. Haynes says: “Children may be particularly susceptible to the neurotoxic effects of ambient [manganese] exposure, as their brains are undergoing a dynamic process of growth and development.”
Two new independent studies conducted in mice suggest that ketogenic diet, also known as “keto diet”, may improve the memory of old subjects and prolong lifespan.
One study was led by Drs. Eric Verdin and John Newman from the Buck Institute for Research on Aging in Novato, USA. Another study was led by Dr. John Ramsey from the University of California, Davis School of Veterinary Medicine.
Both studies checked the effects of four diet types such as ketogenic, low carbohydrate, high fat, and control diet in mice. A team of scientists from the Buck Institute found that a keto diet prevent obesity, reduced mid-life mortality, and prevented memory loss in mice.
Dr. John Ramsey says: “We expected some differences [in mice fed the keto diet], but I was impressed by the magnitude we observed – a 13% increase in median life span for the mice on a high-fat versus high-carb diet. In humans, that would be 7 to 10 years. But equally important, those mice retained quality of health in later life.”
Findings of a recent study published in JAMA Pediatrics suggest that children who were born at 41 weeks seem to have higher levels of cognitive ability compared to those who were born at 39 or 40 weeks. But children born late also may have lower physical functioning.
The study shows that if a child is born full term, they can have better health and cognitive ability while growing up and as they become adults.
Scientists also note that those kids, who are born late, might have an increased risk of health complications. Still they need to have more information about the long-term cognitive and physical consequences of birth after the full term.
Researchers from Northwestern University in Evanston, USA, examined records of more than 1.4 million children for this research.
