Examining sex-based differences in the brain
It may seem obvious, but biological males differ significantly from biological females in many aspects of physiology and behavior. These differences have profound implications for the treatment and prevention of diseases such as cardiovascular disease, asthma, renal failure, cancer, and diabetes — implications long overlooked, but gaining currency perhaps due to the increasing number of...

Predicting rogue behavior
On the afternoon of Nov. 9, 1975, the sturdy and storied freighter SS Edmund Fitzgerald, well known in the Great Lakes region for its record-breaking hauls of iron ore, set out across eastern Lake Superior, carrying a full cargo destined for a Detroit steel mill. En route, it joined a second freighter, the SS Arthur M. Anderson, and by late afternoon of the following day, the two ships were...
