Our weekly roundup of the latest science in the news, as well as a few fascinating articles to keep you entertained over the ...

However, this new study challenges that notion. "We have demonstrated that by using optical vortex beams—light beams that carry angular momentum—we can precisely control how an electron is ejected ...

A new solid-state laser produces 193-nm light for precision chipmaking and even creates vortex beams with orbital angular ...

Researchers from the Chinese Academy of Sciences achieved a breakthrough in deep ultraviolet (DUV) laser technology by ...

Over the years, several waveguides and structured materials have been developed to preserve linear and circular polarization over long distances and analyze these states with a sufficient degree of ...

The polar vortex is a persistent area of low pressure dozens of miles above the earth's poles (both northern and southern). Because the vortex is so high up in the atmosphere, and because it's ...

Physicists at the University of Ottawa add an orbital spin to their laser beams to control the movement of electrons in their ...
