In mice, olive oil given before glucose blunted the early blood sugar rise by slowing the stomach and recruiting glucagon, GLP-1 and the vagus nerve. Here is what that does and does not tell us.
A Science study of 1,543 human milk samples from Canada, Pakistan and Burkina Faso finds shared molecular patterns that tie maternal nutrition, mammary gland function and infant growth together, and points to seven candidate biomarkers.
A team from Wits University and the University of East Anglia shows that a carefully prepared beam of light, starting with no spin at all, can develop separated left- and right-handed regions just by travelling through empty space.
Henri Kagan and Kenso Soai won the 2026 Nobel Prize in Chemistry for non-linear effects and autocatalysis in asymmetric synthesis, work that explains how a tiny imbalance between mirror-image molecules can grow into near purity.
Anthropic says its Claude agents found a new CRISPR-like enzyme system in phage DNA. A Copenhagen researcher says his team had already identified it, and he is asking what data the model saw.
Using ultrafast X-ray pulses, researchers at PNNL and SLAC watched an electron and a proton move through a molecule while the surrounding water rearranged itself in real time, a key step toward better catalysts, fuel cells and flow batteries.
Stanford researchers blocked an age-linked enzyme called 15-PGDH and watched worn knee cartilage thicken in old mice, protect against post-injury arthritis, and even stir to life in human tissue from knee-replacement patients. Exciting, but still early.
A King's College London meta-analysis of 63 studies links cannabis use to higher rates of both committing and experiencing violence. Here is what the numbers show, and why they don't prove cause and effect.
A pilot study of 20 people with depression found that swapping ultra-processed food for a healthier diet was linked to clear improvements in symptoms within weeks. The results are preliminary, but they set up a larger trial.
