A novel strategy to suppress triple negative breast cancer growth

Researchers at Baylor College of Medicine have identified a novel strategy to control the growth of triple negative breast cancer and other cancers. By targeting the enzyme MAPK4, the team found that blocking both AKT and PDK1 can effectively suppress tumor growth, offering new options for treating this devastating disease.

Moderna is safest, most effective mRNA vaccine against COVID-19 for older adults, study shows

A large head-to-head comparison study of the Moderna and Pfizer-BioNTech vaccines found that the Moderna vaccine was associated with a slightly lower risk of adverse events for older adults. The study also showed that the Moderna vaccine was linked to a 4% lower risk of pulmonary embolism and a 15% lower risk of diagnosed COVID-19.

A boost in dopamine during adolescence permanently amplifies dopamine function, impulsivity, and aggression in mice

Researchers found that blocking dopamine transporters during mid-adolescence increases adult aggression, impulsivity, and the behavioral response to amphetamine in mice. Artificially stimulating dopaminergic neurons also exacerbated impulsive behavior in tasks. The study suggests potential harm from stimulant exposure in healthy teens ...
