"New research from Michigan State University challenges the popular assumption that narcissists gradually damage their relationships over time".

"Narcissists have two different ways to maintain their inflated positive self-perceptions," said Gwendolyn Seidman, lead author of the study and associate professor in MSU's Department of Psychology. "They can puff themselves up by trying to impress others (narcissistic admiration) or they can put other people down to show they are superior to them (narcissistic rivalry)."

"The study found that the rate of decline was no steeper for couples where one partner scored highly on narcissism. This suggests that long-term effects of narcissism on romantic relationships may unfold in ways that are more nuanced than previously thought".

Summary: For children with ADHD, a simple run on the treadmill might not be enough. A multicenter randomized clinical trial (RCT) reveals that integrated cognitive-motor exercise—movement that requires thinking and rule-following—is significantly more effective than standard aerobic exercise.

While both types of movement reduce core symptoms like hyperactivity, the “high-load” integrated program specifically sharpens inhibitory control and working memory. By forcing the brain to remember rules and switch tasks while moving, this 12-week program “trains” the mental systems responsible for self-control, offering a powerful, drug-free adjunct for ADHD management.

Being optimistic about the future may help people save more money, and the effect appears strongest among those with lower incomes, according to research published by the American Psychological Association.

The study found that people who scored higher on measures of “dispositional optimism”—the tendency to expect positive outcomes—saved more money over time compared with their less optimistic peers.

The research was published in the Journal of Personality and Social Psychology.

Summary: The cultural stereotype of older age as a time of asexual “friendship” is being dismantled by new research. A study of single adults aged 60 to 83 found that an overwhelming 97% consider sex a vital part of a romantic relationship, with 72% stating they wouldn’t even pursue a partner if sexual intimacy wasn’t on the table.

Just seven days of meditation and mind-body techniques triggered dramatic shifts in brain function, immunity, and metabolism. The changes were so profound they resembled psychedelic experiences—achieved naturally through focused mental practice. Credit: Shutterstock

Excerpts:

A study from the University of Oulu found that large variations in bedtime could double the likelihood of serious cardiac events, especially among people who sleep less than eight hours per night.

The researchers reported that irregular bedtimes and greater variation in sleep timing were strongly connected to an increased risk of major cardiovascular events. This link was most evident in participants whose time in bed was under eight hours, where the risk was about twice as high compared with those who followed more consistent sleep schedules.

In contrast, inconsistent wake-up times did not show a clear association with cardiac risk. Major cardiovascular events in the study referred to conditions requiring specialized medical care, such as myocardial infarction or cerebral infarction.

Summary: New research suggests that dietary boredom might actually be a weight-loss superpower. The study found that adults who followed highly routinized eating patterns—repeating the same meals and maintaining steady calorie counts—lost significantly more weight than those who ate a high-variety diet.

Researchers explain that in a modern world full of overwhelming food choices, creating “go-to” meals reduces the “decision fatigue” and self-control required to stay on track, making healthy eating feel automatic rather than a constant struggle.
