A new study found that children exposed to maternal antenatal corticosteroid treatment have a higher risk of emotional, behavioral and psychological development disorders than nonexposed children. The study, published in JAMA, suggests that the long-term benefits and harms of this treatment should be carefully weighed.
Researchers found that exposing people to prosocial models and modeling elicits subsequent helpful acts, driven by goal contagion. People are more motivated to help after witnessing others benefit from the model than when they themselves benefit. This framework can influence new prosocial behaviors amid the pandemic.

Researchers examined Hadza adults' activity patterns, finding they spent nearly 10 hours a day in nonambulatory postures similar to industrialized populations. However, Hadza adults spent more time in squatting and kneeling postures, which produce muscle activity, suggesting humans need daily muscle activity from both movement and resting
A new study suggests that squatting and kneeling may be important resting positions in human evolution, as they involve higher levels of muscle activity. This could reduce the health risks associated with sedentary behavior, particularly cardiovascular disease.

The team found that L3 neurons, sensitive to brightness, are active in low-light conditions and play a crucial role in detecting sudden changes in luminance.
A study published in Psychotherapy and Psychosomatics found that individuals with eating disorders use exercise as a coping mechanism for depressive mood and negative thoughts. Exercise can temporarily improve their mood, but this effect is short-lived, leading to a vicious cycle of increased exercise.

Children aged 10-12 were nearly three times more likely to make healthy eating decisions after watching a TV cooking program featuring healthy food. The study found that children who watched the healthy program were far more likely to choose a healthy snack option, an apple or cucumber.
A study published in the Journal of Occupational and Organizational Psychology found that individual psychological ownership boosts personal engagement and creativity, but decreases collective effort. Conversely, collective ownership enhances team engagement, but not necessarily individual performance.
Squid exhibit strong alarm behaviors when exposed to underwater pile driving noise, which can be associated with offshore wind farms. The study found that fast habituation may make squids more vulnerable to predation, while longer periods between pile driving activity may discourage long-term habituation.
