Researchers at the University of Basel in Switzerland say that they have made the first ever direct measurements of the strength of the tiny van der Waals forces passing between individual atoms. Though weak compared with covalent bonds, van der Waals forces are fundamental for the function of biological systems and define the properties of many organic compounds.
Forget Graphene and Carbon Nanotubes, Get Ready for Diamond Nanothread: The discovery of a stable form of one-dimensional diamond has scientists racing to understand its properties. The first signs are that diamond nanothread will be more versatile than anyone expected.
The Cartwheel Galaxy is the result of two galaxies that collided about 700 million years ago. The outside ring is comprised of hot blue stars, formed from waves of density moving outwards following the collision. It's a bit larger than the Milky Way, and is located in the constellation Sculptor. It's about 500 million light years distant, or nearly 3 sextillion miles.
