In classical physics, anything driven hard enough will eventually heat up, lose coherence, and settle into disorder. A new ...

A team of physicists has created a cloud of ultracold atoms that stubbornly resists the most basic rule of everyday experience: when you pump energy into something, it heats up. Instead, this quantum ...

When temperatures soar, so do heart attacks. Now, a lab experiment explains just how temperatures climbing into Fahrenheit’s three-digits can cause ischemia and potential heart attacks, all while ...

When a spacecraft enters a thick atmosphere at a high velocity, it rapidly compresses the gas in front of it. This creates temperatures high enough to ionize the gas molecules into a hot, dense plasma ...
