Manipulating atoms one at a time with an electron beam

The ultimate degree of control for engineering would be the ability to create and manipulate materials at the most basic level, fabricating devices atom by atom with precise control.

Relativistic self-focusing gives mid-IR driven electrons a boost

Conventional particle accelerators can range from large room-sized devices to facilities multiple kilometers across. One of the ways that scientists have looked to reduce the size and expense of future accelerators is by ...

Relativistic electrons uncovered with NASA's Van Allen Probes

Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA's ...

Einstein in an iron crystal

Tiny relativistic effects form the basis of the functionalities in modern technology, as exemplified in magnetic hard disks and data storage media. Now for the first time, scientists have directly observed features in an ...

Giant radio flare of Cygnus X-3 detected by astronomers

(Phys.org)—Russian astronomers have recently observed a giant radio flare from a strong X-ray binary source known as Cygnus X-3 (Cyg X-3 for short). The flare occurred after more than five years of quiescence of this source. ...

Research resolves a debate over 'killer electrons' in space

New findings by a UCLA-led international team of researchers answer a fundamental question about our space environment and will help scientists develop methods to protect valuable telecommunication and navigation satellites. ...
