Every science story from the last two weeks of One Turn, newest first. Each links to its sources and to its place on the 3D globe.
The STAR experiment at Brookhaven's Relativistic Heavy Ion Collider reported strong evidence that colliding oxygen nuclei creates quark-gluon plasma, the matter that existed just after the Big Bang. Separately, astronomers measured helium formed in the universe's first minutes with record precision.
Satellite observations revealed ground movements pointing to two magma sources under Masaya volcano, near about 2 million people. Researchers say the findings could improve eruption forecasting.
Physicists who uncovered altermagnetism, a newly recognised form of magnetism challenging a century of established physics, have won a major prize. The discovery could transform future computing and electronics.
The General Conference on Weights and Measures voted to stop adding leap seconds and make UTC continuous from 20 May 2027. A leap hour will be used when needed to reconcile UTC with atomic time.
Astronomers identified WD J1330+6435 as the first known green star, according to a study in RAS Techniques and Instruments.

A study in RAS Techniques and Instruments reports the discovery of WD J1330+6435, described as the first known green star.
Archaeologists excavated a shipwreck at Kekova dated to around 2700–2400 BC, described as the oldest known shipwreck in the world.
French chemist Henri B. Kagan and Japanese chemist Kensō Soai shared the Nobel Prize in Chemistry. They were honoured for discovering non-linear effects and autocatalysis in asymmetric organic synthesis.
The Seychelles Islands Foundation and the University of Exeter reported that roughly 180,000 Aldabra giant tortoises live on the Seychelles islands.
