Differences in children’s behavior predict midlife health behaviors, study finds

A recent study by the Faculty of Sport and Health Sciences at the University of Jyväskylä and the Gerontology Research Center (Finland) investigated the paths from childhood socioemotional behaviour to midlife health behaviour decades later. Socioemotional behaviour at age 8 predicted health behaviour both directly and indirectly through education. There are a wide variety of factors behind health behaviour and […]

‘Surprisingly simple’ arithmetic of smell

Adding and subtracting certain neurons tells researchers whether or not a locust can smell an odor. Smell it inside or outside; summer or winter; in a coffee shop with a scone; in a pizza parlor with pepperoni — even at a pizza parlor with a scone! — coffee smells like coffee. Why don’t other smells or different environmental factors “get […]

Neuroprotective mechanism altered by Alzheimer’s disease risk genes

The brain has a natural protective mechanism against Alzheimer’s disease, and researchers at Baylor College of Medicine, Texas Children’s Hospital and collaborating institutions have discovered that gene variants associated with risk of developing the disease disturb the protective mechanism in ways that can lead to neurodegeneration. The researchers also showed in a fruit fly model of the condition that a […]

Marine omega-3 supplementation fails to prevent depression

The use of marine omega-3 supplements by adults does not appear to prevent the onset of depression, researchers reported on Dec. 21, 2021 in JAMA/Journal of the American Medical Association. “Among adults aged 50 years or older without clinically relevant depressive symptoms at baseline, treatment with omega-3 supplements compared with placebo yielded mixed results, with a small but statistically significant […]

Researchers boost human mental function with brain stimulation

In a pilot human study, researchers from the University of Minnesota Medical School and Massachusetts General Hospital show it is possible to improve specific human brain functions related to self-control and mental flexibility by merging artificial intelligence with targeted electrical brain stimulation. Alik Widge, MD, PhD, an assistant professor of psychiatry and member of the Medical Discovery Team on Addiction […]

A co-worker’s rudeness can affect your sleep – and your partner’s

Rudeness. Sarcastic comments. Demeaning language. Interrupting or talking over someone in a meeting. Workplace incivilities such as these are becoming increasingly common, and a new study from Portland State University and University of Illinois researchers found this behavior has the potential to not only negatively affect an employee’s sleep but their partner’s as well. The study, recently published in the […]

Men experience more emotional pain during breakups

A new study of online relationship support finds that men tend to experience emotional pain more than women when their relationship takes a turn for the worse. An international team of psychologists led by researchers at Lancaster University conducted the first-ever “big data” analysis of relationship problems. The study began as an attempt to create a map of the most […]

Cognitive behavior therapy conducted by telephone may ease arthritis-related insomnia

A new study revealed that a talk therapy practice conducted by telephone could help older adults who have arthritis-related insomnia sleep better. The study was published in the Journal of the American Geriatrics Society. Why does this matter? Insomnia is a difficulty in falling or staying asleep. It affects more than 14 million Americans aged 65 and older. It may lead to daytime problems […]

Lithium imaging method could shine new light on bipolar disorder, treatment

Since 1949, lithium has been a mainstay for treating bipolar disorder (BD), a mental health condition marked by extreme mood swings. But scientists still don’t have a clear understanding of how the drug works, or why some patients respond better than others. Now, researchers reporting in ACS Central Science developed a method for imaging lithium in living cells, allowing them to discover […]

Brain refreshing: Why the dreaming phase matters

Scientists have long wondered why almost all animals sleep, despite the disadvantages to survival of being unconscious. Now, researchers led by a team from the University of Tsukuba have found new evidence of brain refreshing that takes place during a specific phase of sleep: rapid eye movement (REM) sleep, which is when you tend to dream a lot. Previous studies […]
