A team at the University of California, Los Angeles, has used CRISPR to turn up two autism risk genes in lab-grown human neurons and cortical organoids — pea-sized clumps of brain tissue grown from stem cells.
The Food and Drug Administration is requiring a warning about a rare eye condition on the labeling of every approved GLP-1 drug — the class used for type 2 diabetes and weight loss that includes Ozempic, Wegovy, Mounjaro and Zepbound.
Elegant in principle. In broad-leaved plants, however, low efficiency and results that vary from one target site to the next have held it back — which is a polite way of saying it often didn't work well enough to be useful.
Theory has a clean prediction about aging stars: when a Sun-like star exhausts the hydrogen in its core, the core contracts, the outer layers balloon, and the star swells into a red giant.
A star behind the galaxy cluster MACS J0308.9+2645 ran out of fuel, collapsed, and threw most of itself into space. The light from that explosion was detected in James Webb Space Telescope images taken on August 23, 2025 — a faint spot hidden behind a bright foreground star.
In 2025, the conjecture was proved by Natalie Behague, Daniel Iľkovič, and Richard Montgomery, mathematicians at the University of Warwick's Mathematics Institute; Iľkovič is also affiliated with Leipzig University.
A study in mice has pulled apart two effects of psilocybin that normally arrive together: the rewiring of connections between brain cells, and the head twitching that researchers use as a rodent stand-in for a hallucination.
So the usual cardiovascular suspects sat this one out.
We encounter the electrostatic properties of plastics every day. Synthetic fabrics cling. Dust settles on plastic surfaces. In industrial settings, accumulated charge can damage electronics or ignite flammable vapors. Familiar annoyances, occasionally hazards.
There is a particular kind of scientific result that feels less like a breakthrough and more like a quiet correction to something we assumed was obvious.
