A study on Stegodyphus tentoriicola spiders reveals that relatedness fosters better group dynamics and more efficient food foraging. This cooperative behavior helps maintain harmony in larger groups, countering the 'tragedy of the commons' phenomenon.
A recent study published in BMC Biology identified genetic pathways associated with moderate alcohol consumption, but found no correlation between these genes and alcohol dependence. The research team found that drinking behavior was linked to pleasure and reward pathways in the brain, similar to satiety and appetite for food.
Researchers found that men and women who consume low amounts of alcohol have higher healthcare costs compared to non-drinkers. The study challenges the common assumption that moderate drinking is good for your health.
Researchers developed a molecular diagnostic tool that uses targeted genetic sequencing to screen for variations in 362 genes associated with mitochondrial disease. The new method accurately identified the mutation underlying each patient's condition, increasing sensitivity for diagnosing previously unknown genes.
A new study has identified a possible link between autism and non-DNA sequence mutations in the oxytocin receptor gene, OXTR. The research found that this alteration is present in both peripheral blood cells and the brain's temporal cortex, suggesting a major role in human development.

A new perspective suggests considering 'stemness' as a system property, rather than individual cell traits, which may lead to improved understanding of cancer stem cells.
A recent study published in BMC Emergency Medicine found that 60% of unintended incidents in the emergency department are caused by human failures. The majority of these events were attributed to departments outside the emergency department, such as laboratories.
Researchers found that male juvenile delinquents often misinterpret facial expressions of disgust as anger, leading to a more intense emotional response and aggressive behavior. This bias towards misrecognizing others' emotions could result in delinquents perceiving situations as hostile.
New research shows that binge drinking inhibits production of pro-inflammatory cytokines, impairing immune system activation. The study found that alcohol suppresses TLR4's signaling, leading to a prolonged risk of infection
Researchers found a strong association between teenage birth rates and state-level measures of religiosity in the US. Conservative religious beliefs are strongly predicted to influence teen birth rates, even after controlling for income differences.
Researchers define 'gut feelings' experienced by GPs as two types: sense of alarm and reassurance. The former involves feeling uneasy about possible adverse outcomes, while the latter means feeling secure despite uncertainty. This definition aims to facilitate future research on the effectiveness of 'gut-compass'.
