    AI model predicts atomic motion in molecular simulations, boosting speed nearly 100-fold

    An international team of researchers has developed an artificial intelligence model that can predict the motion of atoms in molecular systems directly, dramatically speeding up simulations used in chemistry, physics, and materials science. The model, called MDtrajNet, bypasses the traditional step-by-step calculations of atomic positions, a process that can require millions of steps and substantial computing power.

Bison winter migration to farmland linked to changes in reproduction, study finds

European bison are increasingly migrating from forest habitats into agricultural areas during winter, where they feed on green crops such as rapeseed instead of dry hay, a shift scientists say may be affecting their reproductive biology.
