Chirality is a property of some molecules, subatomic particles, living organisms and other physical or biological systems. This property entails a lack of mirror symmetry in these systems' underlying structures.
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth somewhere near Purdue University and is one of the few meteorites ...

A pair of climate scientists at the Institute for Atmospheric and Climate Science ETH Zurich, working with a colleague from Stripe Inc., has found evidence suggesting that the only way to prevent the planet from continuing ...
Using ESO's Very Large Telescope (VLT), an international team of astronomers has inspected an icy protoplanetary disk of a young star known as PDS 453. Results of the new study, published on the preprint server arXiv, yield ...
Scientists from Université de Lille, France, Linköping University, Sweden, and collaborating institutions have introduced MassiveFold, a new version of AlphaFold that dramatically reduces computing time for protein structure ...
The chances of intelligent life emerging in our universe—and in any hypothetical ones beyond it—can be estimated by a new theoretical model which has echoes of the famous Drake Equation.
