How earthquakes deform gravity

Lightning—one, two, three—and thunder. For centuries, people have estimated the distance of a thunderstorm from the time between lightning and thunder. The greater the time gap between the two signals, the further away ...

Nano antennas for data transfer

Physicists from the University of Würzburg have converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in size.

Researchers discover molecular light switch in photoreceptor cells

How our eyes detect and respond to changes in light intensity is determined by specialized cells in the eye called photoreceptors. In addition to converting light into electrical signals, effectively allowing us to see, rod-shaped ...
