The accelerating effort to understand the mathematics of quantum field theory will have profound consequences for both math and physics.

Venus may be a toxic hell-planet, but new evidence suggests it might have more in common than Earth than we realized.

A ghostly "hand" reaching through the cosmos has just given us new insight into the violent deaths of massive stars.

Camels have an incredible ability to survive weeks without taking even a sip of water. Now, we have a better idea of the secret ingredient that helps their bodies achieve this.

For the first time, scientists have unambiguously confirmed the collision of a black hole and a neutron star: The fateful moment two extreme objects come together in an event so immensely powerful, its ripples across the cosmos can still be discern
