Mechanical vibration generated by electron spins

Micro mechanical elements are indispensable components of modern electrical devices, but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. ...

The mast is raised for NASA's Mars 2020 rover

In this image, taken on June 5, 2019, engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, take a moment after attaching the remote sensing mast to the Mars 2020 rover in the Spacecraft Assembly Facility's ...

Making metal with the lightness of air

Gold, silver and copper are heavy metals, but LLNL scientists can now make them nearly as light as air—in a form so tiny it can ride on a mosquito's back.

Researchers discover new technique to test for viral infections

A team of Colorado State University researchers has developed technology that can detect extremely small amounts of antibodies in a person's blood. Antibodies develop to infect cells or kill pathogens, essentially fighting ...

Tiny sensors, big potential

The electrical energy from batteries powers not only the ignition system that turns the engine and moves electric vehicles but also powers almost every sensing feature of today's automobiles. Electricity turns on the car ...
