Secrets of solar flares can now be studied on Earth

Solar flares, cosmic radiation, and the northern lights are well known phenomena. But exactly how their enormous energy arises is not as well understood. Now, physicists at Chalmers University of Technology, Sweden, have ...

From insulator to conductor in a flash

In recent decades, computers have become faster and hard disks and storage chips have reached enormous capacities. But this trend cannot continue forever. Physical limits are preventing silicon-based computer technology from ...

Hard X-ray flash breaks speed record

Reactions in solar panels, catalytic converters, and other devices are governed by the quick motion of electrons. To capture the movement of these electrons, scientists use pulses of extremely high energy x-rays. The challenge ...

Ultrashort laser pulses make greenhouse gas reactive

It is a long-cherished dream: Removing the inert greenhouse gas carbon dioxide from the atmosphere and using it as a basic material for the chemical industry. This could address two major problems at once by containing climate ...

Controlling skyrmions with lasers

EPFL scientists have produced controllable stable skyrmions using laser pulses, taking a step towards significantly more energy-efficient memory devices. The work is published in Physical Review Letters.

A laser focus on super water-repellent metals

In a laboratory at the University of Rochester, researchers are using lasers to change the surface of metals in incredible ways, such as making them super water-repellent without the use of special coatings, paints, or solvents.
