Crowd in Pamplona’s town hall square at the start of the San Fermín festival

Basic science · Nov 10, 2026Why can a dense crowd start to sway?Crowd measurements in Pamplona reveal that a critical density can give rise to coordinated orbital movements. A model explains the role of confinement and a particular kind of friction.

Titan in front of Saturn and its rings in an image captured by Cassini.

Space · Nov 8, 2026Dragonfly: a name bound for Titan, and a prebiotic chemistry missionNASA invites you to send your name aboard a Dragonfly chip. Scheduled to reach Titan in 2034, the probe is to fly between several sites and analyse their prebiotic chemistry.

Raindrops form ripples in a puddle on sandy ground.

Science · Nov 8, 2026Petrichor: how rain brings the smell of the earth to the surfaceMolecules from soil and plants contribute to the smell of rain. Experiments filmed at very high speed shed light on how raindrops set them circulating again.

Space · Nov 2, 20262026 ED138: what the candidate for dwarf-planet status really revealsSpotted in Rubin data, this distant body also appears in TESS archives. Its orbit is becoming clearer, but its size and shape remain to be established.

Three people discuss in front of a mathematical blackboard, illustrative photograph.

AI · Nov 1, 2026OpenAI and Yang–Mills: understanding the announcement without confusing the evidenceOpenAI claims to have proved existence in quantum physics. The Yang–Mills problem also requires a mass gap: here are the key distinctions for understanding the announcement.

View of Grenoble, the Isère and the surrounding hills from the area around the Bastille.

Innovation · Nov 1, 2026CEA Grenoble: from former reactors to the technologies of tomorrowWhy did CEA Grenoble change direction? From dismantled reactors to the FAMES pilot line, a change of focus to distinguish from ILL’s activities.
