Scientists from the University of Bremen set a new low-temperature record. They cooled matter in a tower to an extremely low temperature: 38 trillionths of a degree warmer than absolute zero. Nowhere in the universe can be any colder, so the coldest place in the Universe moves back on Earth again.

Why we can stop worrying and love the particle accelerator
What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and the very nature of matter. Particle accelerators allow physicists to study subatomic particles by …

But …
The Melting Points of 80 Elements, Substances, and Metal Alloys
Have you ever wondered why plastic melts in a bonfire, but a cast iron pan doesn’t? A bonfire can reach temperatures as hot as 2,012 °F (1,100 °C). Most PET plastic melts at a measly 491 °F (255 °C), so it doesn’t stand a chance! Cast iron prevails with an average melting point of 2,100 …
