Flashes of femtosecond laser light, lasting just a few trillionths of a second, have made it possible to observe new magnetic ...

Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins ...

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

For millennia, humans had one obvious and reliable source of light – the Sun – and we knew the Sun was essential for our survival. Early religions were also often tied up with healing. Sick people ...

Turn on a light outside at night, and it won't be long before a bevy of insects start careening wildly around it, apparently drawn in "like a moth to a flame," as the saying goes. Now, in a series of ...
