New research at Penn State found that close, supportive relationships with parents, especially dads, can help stave off certain adjustment problems during adolescence. The study showed that father-adolescent intimacy was associated with fewer depressive symptoms and weight concerns across most of adolescence.
Researchers found five aspects underlie feelings of repugnance: moral outrage, regulation desire, monetary value translation, exploitation concern, and seller risk exposure. Transactions triggering strong repugnance often require policy interventions to protect vulnerable individuals or address unknown risks.
BioAesthetics Corp., a Tulane University spin-out company, has received a $256,000 grant to develop a novel graft for treating pelvic organ prolapse (POP). The graft, strengthened with biodegradable polymers, will be tested in Kristin Miller's lab to compare its elasticity and strength to normal tissue.
A recent study funded by NIH found that excessive daily screen time is associated with cognitive and behavioral issues in extremely preterm children. Children who spent more than two hours on screens per day had lower IQ scores and poorer problem-solving skills compared to their peers.
A new study found that teens with secure family relationships at age 14 provide greater empathic support to their close friends across adolescence. They also tend to receive more support from their friends, suggesting a reciprocal relationship between the two.

Researchers found that people tend to stick to their original estimate or adopt the nearest peer's estimate, compromising only when peers are not in close agreement. This 'egocentric discounting' effect is influenced by the consistency of others' beliefs with one's own, leading to prioritization of confirmation over conflicting views.
Researchers found that face masks made of hybrid polymer materials can filter particles efficiently while cooling the face. Consistent mask-wearing by at least 70% of the public could lead to the eradication of COVID-19 if efficient masks are used, according to epidemiological studies.
