No evidence of an influence of dark matter on the force between nuclei
The universe mainly consists of a novel substance and an energy form that are not yet understood. This 'dark matter' and 'dark energy' are not directly visible to the naked eye or through telescopes. Astronomers can only ...

Radio burst inside Milky Way may give clues about fast radio bursts
Radio observatories around the world have reported capturing a unique event—a strong, millisecond-long burst of radio waves coming from a type of neutron star inside the Milky Way. Because of its strength, space scientists ...
Galaxy formation simulated without dark matter
For the first time, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified ...

Researchers estimate the mass of the Milky Way to be 890 billion times that of our sun
An international team of researchers has used sophisticated models to calculate the mass of the Milky Way. They have written a paper describing their efforts and results, and have posted it on the arXiv preprint server.
The Apollo experiment that keeps on giving
Neal Armstrong, Buzz Aldrin and Michael Collins departed from the moon 50 years ago, but one of the experiments they left behind continues to return fresh data to this day: arrays of prisms that reflect light back toward ...

Climbing droplets driven by mechanowetting on transverse waves
Modern applications use self-cleaning strategies and digital microfluids to control individual droplets of fluids on flat surfaces but existing techniques are limited by the side-effects of high electric fields and high temperatures. ...
