A new German study, published in the journal Cell Reports, suggests that parents may boost the intelligence of their offspring by exercising.
The research, using a mice model, showed that active mice are more likely to have offspring with the higher ability to learn compared to mice whose movement was restricted. German researchers identified that “microRNA” molecules which were known to promote this neuron connectivity in the brain, as well as in the sperm, in response to exercise.
Study author Professor André Fischer from the German Center for Neurodegenerative Disease says: “Presumably, [miRNA212 and miRNA132] modify brain development in a very subtle manner improving the connection of neurons. This results in a cognitive advantage for the offspring.”
A recent study, published in the journal Scientific Reports, finds that children aged between 9 and 11 years who ate fish at least once a week had higher IQ scores and better sleep qualify than children who ate fish seldom.
For the study, a team of researchers assessed the fish consumption of 541 children from China aged 9–11. They used a dietary questionnaire to find out how much fish they consumed during the previous month.
Study co-author Prof. Adrian Raine, of the School of Arts and Sciences at Penn State’s Perelman School of Medicine, explains: “Lack of sleep is associated with antisocial behavior; poor cognition is associated with antisocial behavior. We have found that omega-3 supplements reduce antisocial behavior, so it’s not too surprising that fish is behind this.”
A new study, published in The BMJ, reports that children with higher IQ are believed to have higher chances of longer life and lower risk of such diseases as heart disease, stroke, smoking-related cancers, respiratory disease, and dementia.
For the study, the researchers collected data from 33,526 and 32,229 women born in Scotland in 1936, who took validated childhood intelligence test at age of 11, and who could be followed to cause of death data up to December 2015.
Scientists say: “Importantly, it shows that childhood IQ is strongly associated with causes of death that are, to a great extent, dependent on already known risk factors. Tobacco smoking and its distribution along the socioeconomic spectrum could be of particular importance here.”
A study from King’s College London and the Seaver Autism Center finds that boys born to older fathers are more intelligent, more focused on their interests and are less concerned about fitting in. These qualities help them to be more successful in school and careers.
For the study, a team of researchers analyzed data received 15,000 pairs of twins who completed online tests at age 12 to measure their “geek-like” traits, including non-verbal IQ, focus, and social aloofness. The researchers also received data from their parents.
Study author Magdalena Janecka, a postdoctoral fellow at the Seaver Autism Center at the Icahn School of Medicine at Mount Sinai, New York City, says: “We have known for a while about the negative consequences of advanced parental age but now we have shown that these children may also go on to have better educational and career prospects.”
Taking medication that lowers cholesterol levels is crucial for patients who survived a heart attack. In a new study, published in the European Journal of Preventive Cardiology, a team of researchers from Uppsala and Umea Universities found that men with higher general cognitive ability (intelligence) were better at taking prescribed statins.
In the study, the cognitive ability of nearly 2,500 patients had been measured about 30 years before the heart attack, when their compulsory military service began. The researcher discovered a link between low intelligence and the higher risk of not taking prescribed meds.
John Wallert, a clinical psychologist and PhD student at Uppsala University, says: “It’s very important for the patients themselves to take personal responsibility for their health after the heart attack — taking their medication, eating a healthy diet, taking exercise and not smoking. This study inspires hope that we might’ll be able to provide better, improve tailor-made care, based on the patients’ cognitive capacity.”
