(Phys.org)—Imagine a clock that will keep perfect time forever, even after the heat-death of the universe. This is the "wow" factor behind a device known as a "space-time crystal," a four-dimensional crystal that has periodic ...

(PhysOrg.com) -- "Many scientists, like me, have an interest in the simplest molecules," Stefan Klotz tells PhysOrg.com. "These simple molecules, like water, nitrogen and oxygen, are in quite of the lot of stuff around us, ...
(Phys.org)—When exposed to a varying magnetic field, some conductive materials undergo a temperature increase of about 3-5 K over several minutes. This effect is called induction heating, and it occurs because small electric ...
(Phys.org) —Superconducting materials exhibit unexpected behaviors when subjected to magnetic fields or high pressures –discoveries that have implications for controlling electrons in those special materials. According ...
