The hunt for a natural molecule that can release cellular energy

All cells in the human body—and the motions they enable, from our beating hearts to our wiggling toes—use energy generated by a molecule called ATP. Its energy is thought to be released to fuel cellular processes in only one way: when ATP's decomposition is initiated by an enzyme, a specific typ...

The Universe can outrun light without breaking Einstein’s rules

Cosmic expansion allows distant galaxies to move away faster than light, while still letting us see ancient light they emitted when they were much closer. Eventually, accelerating expansion will push nearly every galaxy beyond our Local Group out of sight, making the Universe appear almost empty.
