Physicists theorize that a new “traversable” kind of wormhole could resolve a baffling paradox and rescue information that falls into black holes.

Studies of the energy-harvesting proteins in primitive cells suggest that key features of photosynthesis might have evolved a billion years earlier than scientists thought.

Simple math can help scheming politicians manipulate district maps and cruise to victory. But it can also help identify and fix the problem.

The real-world version of the famous “traveling salesman problem” finally gets a good-enough solution.

Mitonuclear conflict — a struggle between the genes in a cell’s nucleus and those in its mitochondria — might sometimes split species in two. 1

The universe has not cooperated with physicists’ hopes. In desperation, many are looking for new ways to search for surprises at the Large Hadron Collider.

A new idea called the “information bottleneck” is helping to explain the puzzling success of today’s artificial-intelligence algorithms — and might also explain how human brains learn.

Two mathematicians have proved that two different infinities are equal in size, settling a long-standing question. Their proof rests on a surprising link between the sizes of infinities and the complexity of mathematical theories.

Reductionism breaks the world into elementary building blocks. Emergence finds the simple laws that arise out of complexity. These two complementary ways of viewing the universe come together in modern theories of quantum gravity
