A new way to measure gravity: Using floating atoms

A team of researchers at the University of California, Berkeley, has found a new way to measure gravity—by noting differences in atoms in a superposition state, suspended in the air by lasers. In their paper published in ...

Lightning flashes illuminate storm behavior

Anybody who has ever tried to photograph lightning knows that it takes patience and special camera equipment. Now, a new study is using those brief but brilliant flashes to illuminate cloud structures and shed light on storm ...

How fireflies glow and what signals they're sending

You might not really be sure you saw what you think you saw when the first one shows up. But you stare in the direction of the flicker of light and there it is again—the first firefly of the evening. If you are in good ...

Flashes on the moon

It happens several times a week. Sometimes it is only short flashes of light that appear on the surface of the moon. Other light phenomena on the Earth's satellite can last longer. And sometimes there are also places that ...

Ultrafast snapshots of relaxing electrons in solids

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole behind. For a long time, scientists have suspected that the liberated ...

X-ray laser FLASH reveals fast demagnetisation process

(Phys.org)—Scientists from TU Berlin, DESY and the University of Paris discovered a surprising effect in the demagnetisation of ferromagnetic materials at DESY's free-electron laser FLASH. The team of researchers headed ...
