(Phys.org) —Having the photoreceptors at the back of the retina is not a design constraint, it is a design feature. The idea that the vertebrate eye, like a traditional front-illuminated camera, might have been improved ...
(Phys.org) —For 112 years, the best minds in science haven't been able to fully understand how superconductors do what they do. Last week, Louise Lerner of Argonne National Laboratory, published an article reminding everyone ...
Directing light from place to the place is the backbone of our modern world. Beneath the oceans and across continents, fiber optic cables carry light that encodes everything from YouTube videos to banking transmissions—all ...

The depths of the oceans are home to a complex ecosystem of marine organisms, but also a vast network of cables spanning the globe that aid communications. Earthquakes and tsunamis can potentially damage these important cables. ...
Scientists harnessing precise control of ultrafast lasers have accelerated electrons over a 20-centimeter stretch to speeds usually reserved for particle accelerators the size of 10 football fields.
