Models indicate that climate change will cause more frequent hurricanes, but the overall trend can’t be linked with a particular event, such as Hurricane Sandy (above, on October 29).

Can We Link Hurricane Sandy to Climate Change?

Models indicate that climate change will cause more frequent and intense hurricanes, but the overall trend can’t be linked with any particular storm

Tracking the Twists and Turns of Hurricanes

Incredibly powerful supercomputers and a willingness to acknowledge that they’re not perfect has made weather scientists become much more effective in forecasting hurricanes.

According to author Kevin Dutton, psychopaths have a distinct set of personality characteristics. Pictured is Anthony Perkins as Norman Bates in Psycho.

The Pros to Being a Psychopath

In a new book, Oxford research psychologist Kevin Dutton argues that psychopaths are poised to perform well under pressure
