Study Suggests Magnetic Fields Can Control Heat And Sound

More than a hundred years ago, physicists discovered that heat is simply the energy stored in the vibrations of atoms. This meant that heat and sound are related. Now, for the first time ever, scientists have experimentally shown that these atomic vibrations have magnetic properties, too. » 3/25/15 11:40am Wednesday 11:40am

We Should Be Able To Detect Spaceships Moving Near The Speed Of Light

A pair of engineers say it's possible to detect the signatures of spacecraft traveling at relativistic speeds, and we can do so using current technologies. The trouble is, their new analysis also suggests that moving through space at ludicrous speed is more hazardous than previously thought. » 3/25/15 8:40am Wednesday 8:40am
