The Milky Way is warped

The Milky Way galaxy's disk of stars is anything but stable and flat. Instead, it becomes increasingly warped and twisted far away from the Milky Way's center, according to astronomers from National Astronomical Observatories ...

Clarifying effects of negative mass

A FLEET study led by University of Queensland's David Colas clarifies recent studies of negative mass, investigating the strange phenomenon of self-interference.

Finding trace material in waste materials

Last year Empa's inorganic analytics lab was granted the status of "Reference Laboratory" within the scope of the ProSUM project, funded by the EU. Fine-grained samples of shredder waste from scrapped cars, e-waste or mine ...

Atomic blasting creates new devices to measure nanoparticles

Like sandblasting at the nanometer scale, focused beams of ions ablate hard materials to form intricate three-dimensional patterns. The beams can create tiny features in the lateral dimensions—length and width, but to create ...

Heavy nitrogen molecules reveal planetary-scale tug-of-war

Nature whispers its stories in a faint molecular language, and Rice University scientist Laurence Yeung and colleagues can finally tell one of those stories this week, thanks to a one-of-a-kind instrument that allowed them ...

Most precise measurement of proton mass

What is the mass of a proton? Scientists from Germany and Japan have made an important step toward better understanding this fundamental constant. By means of precision measurements on a single proton, they were able to improve ...
