Life might have originated in droplets that behave surprisingly like living cells.

Researchers have discovered that simple “chemically active” droplets grow to the size of cells and spontaneously divide, suggesting they might have evolved into the first living cells.

Proteins work like rigid keys to activate cellular functions — or so everyone thought. Scientists are discovering a huge number of proteins that shape-shift to do their work, upending a century-old maxim of biology.

Just five days after posting a retraction, László Babai announced that he had fixed the error in his landmark graph isomorphism algorithm.

Gaining an intuition about half-life requires some unintuitive thinking.

Is the brain a blank slate, or is it wired from birth to understand the world?

The ancient study of an object’s curvature is guiding mathematicians toward a new understanding of simple equations.

The legendary graph isomorphism problem may be harder than a 2015 result seemed to suggest.

The biologist Marcus Feldman creates mathematical models that reveal how cultural traditions can affect the evolution of a species.
