We may have a proto-sun to thank for the Earth's solid surface and mild climate, researchers report.

You can blame the freezing weather of the last few weeks on the polar vortex, but what are they and why do they drive temperatures so low?

Researchers trained amachine learning model with data on forecasts and actual weather conditions. The result is an old building that's "smarter" about heat.

Chilly Europeans can blame a "sudden stratospheric warming" in the Arctic. Is the same phenomenon freezing Chicago?

"Supernova explosions and their remnants provide cosmic laboratories that enable us to explore physics in extreme conditions..."

Climate change will drive higher temperatures and higher energy use in China as people crank up the air conditioning.

You might've heard that cold temperatures slow down the aging process, but new research shows that there's more to it than turning down the thermostat.

A new rubbery, shape-shifting material goes from one sophisticated form to another on demand.

A new flexible patch sewn into your clothes could one day keep you warm—and lower your electricity bill at the same time.

Most electronics can't take serious cold or heat, but by mixing two materials, researchers have created a new plastic that could fix that.
