The semaglutide heart trial that changed the obesity-drug conversation, in close-up
The SELECT trial, published in the New England Journal of Medicine in 2023, found semaglutide cut major cardiovascular events by a fifth in adults with existing heart disease and overweight — a benefit independent of diabetes.

How JWST's deep fields scrambled the early-galaxy timeline
Since 2022, infrared surveys have turned up galaxies that appear surprisingly bright and mature within a few hundred million years of the Big Bang — and cosmologists are still arguing about why.

What the next gravity-wave detectors will hear that LIGO cannot
LISA, adopted by ESA in 2024 for launch around 2035, will listen to spacetime ripples from space with arms 2.5 million kilometers long; on Earth, the Einstein Telescope and Cosmic Explorer aim to follow LIGO.
