A Lego Pirate Is Sacrificed To A Colossal Wave In The Name of Science

Rogue waves are a little-understood phenomenon of ocean dynamics. The colossal swells, which seem to appear out of nowhere in otherwise calm seas, were reported for centuries before their existence was confirmed in 1995.

This Is Why the Heat Index Is So Important

Out of the comfort and into the fire went the central United States this week as the latest NotReallyAPolarVortex left in a hurry. Temperatures themselves are hot enough — topping 105°F in places — but as the old phrase goes, it's not the heat that gets you, it's the humidity. On days like today, the heat index is… » 7/23/14 3:25pm Yesterday 3:25pm

Oceans May Be Critical For Life To Arise In Habitable Zones

The Sun Emits a Plasma Arc So Big You Could Fit 25 Earths Beneath It

The sun is big. Really, really big. It's so big, every feature on it is mind-boggling huge.
