Researchers have mapped hundreds of semantic categories to the tiny bits of the cortex that represent them in our thoughts and perceptions. What they discovered might change our view of memory.

Two teams have shown how quantum approaches can solve problems faster than classical computers, bringing physics and computer science closer together.

Large blocks of genes conserved through hundreds of millions of years of evolution hint at how the first animal chromosomes came to be.

We might have a past faint sun to owe for life’s existence. This has consequences for the possibility of life outside Earth.

Studies that map the adaptive value of viral mutations hint at how the COVID-19 pandemic might progress next.

New studies reveal the ancient, shared genetic “grammar” underpinning the diverse evolution of fish fins and tetrapod limbs.

Decades ago, a mathematician posed a warmup problem for some of the most difficult questions about prime numbers. It turned out to be just as difficult to solve, until now.

A new paper shows how to create longer disordered strings than mathematicians had thought possible, proving that a well-known recent conjecture is “spectacularly wrong.”

By carefully constructing a multidimensional and well-connected graph, a team of researchers has finally created a long-sought locally testable code that can immediately betray whether it’s been corrupted.
