Chemists synthesize 'flat' silicon compounds

Chemists at the University of Bonn (Germany) have synthesized extremely unusual compounds. Their central building block is a silicon atom. Different from usual, however, is the arrangement of the four bonding partners of ...

Researchers building a harder diamond, called pentadiamonds

Researchers at the University of Tsukuba used computer calculations to design a new carbon-based material even harder than diamond. This structure, dubbed "pentadiamond" by its creators, may be useful for replacing current ...

Molecular simulations show how drugs block key receptors

Many pharmaceuticals work by targeting what are known as 'G-protein-coupled receptors.' In a new study, scientists from Uppsala University describe how they have been able to predict how special molecules that can be used ...

Pioneering black NASA mathematician Katherine Johnson dies

Katherine Johnson, a mathematician who calculated rocket trajectories and earth orbits for NASA's early space missions and was later portrayed in the 2016 hit film "Hidden Figures," about pioneering black female aerospace ...

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 ...
