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 ...

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. X-rays stream off the sun in this first picture of the sun, overlaid on a picture taken by NASA Solar Dynamics Observatory SDO, ...

As its name suggests, dark matter -- material which makes up about 85% of the mass in the universe -- emits no light, eluding easy detection. Its properties, too, remain fairly obscure. Now, a ...

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 ...

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 ...

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 ...

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 ...

A new theoretical study proposes a radical idea in the search for dark matter—using the surface of Ganymede, Jupiter’s largest moon, as a natural detector for massive dark matter particles. The ...
