Why are men more susceptible to alcoholism?

A new study reveals that men are up to twice as likely to develop alcoholism as women, with increased dopamine release in the brain contributing to this difference. The study found that men had greater dopamine release than women after consuming an alcoholic drink, which may contribute to the initial reinforcing properties of alcohol a...

Study confirms: Whatever doesn't kill us can make us stronger

A new study found that experiencing some lifetime adversity can contribute to the development of resilience, leading to lower global distress, functional impairment, and increased life satisfaction. Researchers analyzed a national sample of 2,398 subjects and discovered a U-shaped relationship between lifetime adversity and outcomes.

How to weigh a star using a moon

New work by astrophysicist David Kipping reveals that astronomers can calculate a star's mass using its orbiting planet and moon. By measuring the size of the planet and moon relative to the star and their orbital periods, scientists can use Kepler's Laws of Motion to determine the density of the star.
