Two studies found that exposure to even cartoonish children's violent video games increases aggressive behavior in children and adolescents. A third study showed that frequent play of violent video games leads to a more aggressive worldview and behaviors in school-aged children. Both studies support the idea that violent video game exp...
A new study from UCSD reveals that California's tobacco control program has led to a significant increase in smoking cessation rates, especially among young adults. Cessation rates have risen by 50% among those aged 20-34, while daily cigarette consumption has declined, particularly among older smokers.
Dr Alwyn Ruddock's extraordinary claims about her research on John Cabot's voyages to America have been explored by Dr Evan Jones of the University of Bristol. Ruddock's findings suggest that Cabot explored a large section of the American coastline, claiming it for England in the process.
Researchers at San Francisco VA Medical Center found that administering glucose to treat hypoglycemia actually causes brain damage in rats, contrary to previous assumptions. Oxidative stress is triggered by the sudden return of glucose, leading to neuron death.
Neurobiologists found that richer individuals are slower to learn associating a stimulus with financial reward, leading to slower brain responses in reward areas. The study also measured marginal utility of money, finding greater wealth reduces the likelihood of picking up coins on the street.
A recent study published in BMC Medicine found that immunomodulatory agents can slow multiple sclerosis progression but are only prescribed to a minority of cases. Women and Caucasians were more likely to receive these treatments, highlighting disparities in care.
