Small and cold, Mars has long been considered a dead planet. But a series of recent discoveries has forced scientists to rethink how recently its insides stopped churning — if they ever stopped at all.

Long considered solved, David Hilbert’s question about seventh-degree polynomials is leading researchers to a new web of mathematical connections.

Inside cells, droplets of biomolecules called condensates merge, divide and dissolve. Their dance may regulate vital processes.

Mistletoes have all but shut down the powerhouses of their cells. Scientists are still trying to understand the plants’ unorthodox survival strategy.

Over the past two years, astronomers have rewritten the story of our galaxy.

An exercise in pure mathematics has led to a wide-ranging theory of how the world comes together.

In a landmark series of calculations, physicists have proved that black holes can shed information.

Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls.

After 44 years, there’s finally a better way to find approximate solutions to the notoriously difficult traveling salesperson problem.
