Did sabertooth tigers purr or roar?

A new study from North Carolina State University found that the shape of small bones in the throat, called hyoid bones, may be key to determining whether sabertooth tigers purred or roared. The researchers compared the anatomy of modern roaring cats and purring cats to find that the missing bones in saber-toothed tigers' hyoid structur...

Genetic study shows that common medication used to prevent heart attacks may be ineffective for majority of British South Asians

A genetic study of 44,396 British people of Bangladeshi and Pakistani ancestry found that 57% have a genetic variant that renders clopidogrel ineffective in preventing recurrent heart attacks. People with two loss of function variants were more than three times more likely to experience recurrent heart attacks due to treatment failure.

New research finds way to reduce bias in children

A study published in the Proceedings of the National Academy of Sciences found that explaining structural causes of inequality can diminish biased views in children. Researchers discovered that when children are told the high-status group created the rules, they report lower levels of bias and perceive the status hierarchy as less fair.
