Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

NYU scientists are using light to precisely control how tiny particles organize themselves into crystals. Their research, published in Chem, provides a simple and reversible method for forming ...

When Michelle Galloway drives to work, she takes a tunnel into a mountain. Deep inside, at the entrance to the facility, guards ask her for a secret password. “Then, this James Bond-type door opens in ...

Although the Standard Model accounts for many aspects of matter, certain questions challenge scientists. Why does our universe contain more matter than antimatter? What is the mysterious substance ...

LIVERMORE, Calif. - Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as ...

Physicists at Stanford University and SLAC have built a contraption they hope will detect dark matter, though exactly which theoretical particles they think they’ll find—hidden photons or little blips ...

Physicists have caught neutrinos from a nuclear reactor using a device weighing just a few kilograms, orders of magnitude less massive than standard neutrino detectors. The technique opens new ways to ...

Some kind of invisible material is out there affecting the motions of stars and galaxies, but thus far, no one has been able to directly detect the substance—called dark matter—itself. But some are ...
