Early-life obesity impacts children’s learning and memory

A new study found that children on the threshold of obesity or overweight in the first two years of life had lower perceptual reasoning and working memory scores than lean children when tested at ages five and eight. The study also indicated that IQ scores may be lower for higher-weight children.

No evidence that anesthesia in young children lowers intelligence

A new study finds no evidence that children given anesthesia before their third birthdays have lower IQs than those who did not have it. A more complex picture emerges among people who had anesthesia several times as small children: Although their intelligence is comparable, they score modestly lower on tests measuring fine motor skills, and their parents are more likely to report behavioral and learning problems.

Poor grades tied to class times that don’t match our biological clocks: Schedules of night owls, morning larks and daytime finches may predict their educational outcomes

It may be time to tailor students’ class schedules to their natural biological rhythms. A study shows that students whose circadian rhythms were out of sync with their class schedules received lower grades due to ‘social jet lag,’ a condition in which peak alertness times are at odds with work, school or other demands.

Alzheimer’s drug repairs brain damage after alcohol binges in rodents: Drug appears to reverse structural and genetic brain changes that affect memory, learning

A drug used to slow cognitive decline in Alzheimer’s disease could offer clues on how drugs might one day be able to reverse brain changes that affect learning and memory in teens and young adults who binge drink.

Running helps brain stave off effects of chronic stress: Exercise protects vital memory and learning functions

The study finds that running mitigates the negative impacts chronic stress has on the hippocampus, the part of the brain responsible for learning and memory.

Outdoor instruction makes students more open to learning

Being taught science subjects outdoors increases student motivation. A study therefore suggests offering more outdoor instruction at the lower secondary level.
