A roundup of recent research that did not make the front page: observations of spooky action at the Large Hadron Collider, evidence of psychoactive use during the Ice Age, and yeast-based methods for building structures on Mars.

The Ice Age finding is the most striking of the group. Trace evidence at an archaeological site in the Alps suggests people were deliberately using plants with psychoactive compounds, which substantially revises assumptions about ritual behaviour in Ice Age Europe.

The Mars work is more immediately practical, and more speculative: engineered yeast producing structural material could in principle replace the structural polymers that are the limiting factor for habitats built far from Earth.

The collider results continue a debate about whether quantum entanglement can be observed at distances where local interactions are ruled out. The measurements remain contested.
