The dynamics of the Higgs and other light scalar fields during inflation can have important cosmological consequences, but because of the infrared problem, they cannot be computed using perturbation ...

Mathematicians have struggled to understand the moduli space of graphs. A new paper uses tools from physics to peek inside. “That’s a super hard problem. It’s amazing they were able to,” said Dan ...

The mystery of how birds migrate long distances over land and sea is a step closer to being cracked. By studying robins, scientists have found clues to how birds sense the Earth's magnetic field. Just ...

Just as you might reach for a magnetic compass to find which way is north or south, birds are thought to have an in-built "living compass". A chemical in the eye that is sensitive to magnetism could ...
