Tiny genetic sequences in a mother’s bacteria seem to hop into the infant’s bacteria, perhaps ensuring a healthy microbiome later in life.

The neural representations of a perceived image and the memory of it are almost the same. New work shows how and why they are different.

A quantum approach to data analysis that relies on the study of shapes will likely remain an example of a quantum advantage — albeit for increasingly unlikely scenarios.

Maintenance of the software that’s used for the hardest physics calculations rests almost entirely with a retiree. The situation reveals the problematic incentive structure of academia.

Researchers discover that to sharpen its control over precision maneuvers, the brain uses comparisons between control signals — not the signals themselves.

New research in fish suggests that gut microbes can have a crucial early influence on the brain’s social development.

Lattice cryptography promises to protect secrets from the attacks of far-future quantum computers.

A growing catalog of huge but dim galaxies such as Dragonfly 44 is forcing astronomers to invent new theories of galactic evolution.

Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates.
