Scientists Produce 'Coldest Cubic Meter in the Universe'

Project in Italy linked to study of matter and antimatter

(Newser) - If you're dreading the winter cold, know that things could be a lot worse. Scientists in Italy have cooled 880 pounds of copper to a temperature approaching absolute zero; that's 0 Kelvin, or -459.67 degrees Fahrenheit, Science Daily reports. The copper reached a temperature of -459.66... More »

Electrons: Nearly Perfect Spheres

New research can help us understand antimatter, scientists say

(Newser) - What is the most round natural object in the universe? Quite possibly the electron, new research finds. London scientists have taken the most accurate measurement to date of the subatomic particle’s shape, and discovered that it is a nearly perfect sphere. It’s off by only 0.000000000000000000000000001cm, meaning... More »

Antimatter Captured for First Time

CERN: Experiment is 'science fiction become science fact'

(Newser) - Atoms of antimatter are instantly destroyed when they come into contact with matter, so capturing them by the dozen was no easy task, say scientists at CERN. A team of scientists at the European institute managed to capture 38 of the atoms for a fraction of a second, each in... More »

Sand May Be 5th State of Matter: Study

(Newser) - Sand exhibits so many unexplainable physical properties that some think granularity is a form of matter unto itself, Wired reports. Granular matter acts like a solid, a liquid, or a gas depending on the circumstance. “You walk on the beach, and the sand supports your weight,” said physicist... More »
