MRI scans show that the brains of infants and toddlers can encode memories, even if we don’t remember them as adults.

Physicists had long assumed that the elusive force has constant strength. But the latest results from a project to map the Universe’s expansion challenge this idea.

The AMPA group of brain receptors have mostly been assumed to be calcium impermeable and so were not thought to contribute to the calcium-dependent mechanisms underlying learning and memory. Observations of calcium permeability in some AMPA-receptor subtypes now overturn those assumptions about these receptors’ properties and their roles in neuronal communication.

Comprehensive maps of mutations in healthy and diseased gastric tissue give clues about how cancer arises and could inform early-detection strategies.

Neural recordings from parrots and songbirds reveal the ways in which vocal production is encoded in the brain, highlighting remarkable similarities between how parrots and humans learn to produce sounds.

A bacterium makes a molecule that kills drug-resistant fungi in an unusual way — by targeting various phospholipid molecules in membranes.

Satellites connect people around the world but they also interfere with astronomers’ views of the cosmos. There are ways to reduce these tensions.
