Just as antibiotics have bred resistance in bacteria, vaccines can potentially lose their effectiveness over diseases they controlled. Researchers are working to head off the evolution of new threats.

Faced with a navigational challenge, neural networks spontaneously evolved units resembling the grid cells that help living animals find their way.

A roundup of some of the most important discoveries gleaned so far from the Gaia space observatory’s new map of the galaxy.

New modeling studies suggest that birds migrate to strike a favorable balance between their input and output of energy.

Zeta values seem to connect distant geometric worlds. In a new proof, mathematicians finally explain why.

Disease-causing viruses and message-carrying vesicles sit at the ends of a spectrum of membranous particles that cells release.

Two ways of measuring the universe’s expansion rate yield two conflicting answers. Many point to the possibility of new physics at work, but a new analysis argues that unseen errors could be to blame.

New observations of extreme astrophysical systems have “brutally and pitilessly murdered” attempts to replace Einstein’s general theory of relativity.

Computer code serves as a useful analogy for what our genes do, but the complexity and messiness of life go well beyond simple analogies and mathematical models.
