Black patients with asthma may fare worse regardless of disease severity

A study of black and white patients with asthma found that blacks were more likely to visit the emergency department or be hospitalized for the condition, even after adjusting for socioeconomic status. The researchers suggest that genetic differences may underlie these racial disparities in asthma outcomes.

If you want more babies, find a man with a deep voice

Research by McMaster University suggests that men's voice pitch affects reproductive success. Men with low-pitched voices have higher reproductive success and more children born to them, while women prefer deeper male voices as more dominant and masculine sounding. The study offers insight into the evolution of human voice preferences.
