Glass shape influences how quickly we drink alcohol

Researchers at University of Bristol found that participants drank more slowly from curved 'beer flute' glasses than straight-sided glass containing lager, suggesting curved glasses compromise ability to gauge liquid levels and pace drinking. This could have positive impact on reducing intoxication and excessive drinking.

Traumatic childhood may increase the risk of drug addiction

Research from the University of Cambridge suggests that a traumatic upbringing during childhood is linked to impulsive and compulsive personality traits, increasing the risk of drug dependence. The study examined 50 adults with cocaine dependence and their biological siblings, finding a direct relationship between traumatic childhoods ...

Biophysicists unravel secrets of genetic switch

Researchers discovered how nonspecific binding plays a critical role in controlling the switch between dormant and virulent states in bacteria. The study used single-molecule techniques to characterize the role of non-specific binding in facilitating the closure of a DNA loop that switches off virulence.

Wayne State's new flexible electronics technology may lead to new medical uses

A new flexible electronics technology developed by Wayne State University's Yong Xu has opened up possibilities for health care and medical applications of electronic devices. The technology is compatible with mainstream CMOS processes, allowing for the creation of high-performance and high-density CMOS circuits on flexible substrates.

IADR/AADR published study estimates high prevalence of periodontis in US adults

A recent study published in the Journal of Dental Research estimates that approximately 47.2% of US adults have periodontitis, with higher rates among males, Mexican Americans, and those with lower education levels. The study also found significant disparities in periodontal disease prevalence across different age groups.

Leaders' emotional cues may predict acts of terror or political aggression

Leaders' expressions of anger, contempt, and disgust in speeches may predict violent acts. Analysis found a significant increase in these emotions before aggression, while decreases were seen before nonviolent resistance. The findings suggest a leader's emotional tone can motivate their group to take part in violent actions.
