When clinical trials are suddenly halted by US funding cuts, there are repercussions for investigators and patients, and they do not stop at borders.

Other researchers question whether autonomous AI scientists are possible or even desirable.

A systematic review and meta-analysis of clinical trials investigating the efficacy and safety of obesity management medications reported tirzepatide and semaglutide to be the most effective in reducing body weight and obesity-related complications.

Human actions have shaped ecosystems for thousands of years, and have profound effects on biodiversity and environmental processes. This Review explores the ways that humans have modified past ecosystems and the methods available for researchers to study these changes, as well as indicating how understanding historic change can inform conservation strategies.

The 2025 Nobel Prize in Chemistry has been awarded to Susumu Kitagawa, Richard Robson and Omar M. Yaghi “for the development of metal–organic frameworks.”

Marine ecosystems face threats from human-induced stressors like climate change, pollution, and habitat loss. Despite international endeavors, significant gaps remain in understanding ocean dynamics. This article presents six policy recommendations to integrate plankton populations into conservation frameworks. These could be leveraged in the process approved at CBD’s COP16 in Colombia to update criteria for defining ecologically or biologically significant marine areas (EBSAs) and supporting science-based Marine Protected Area (MPA) designations.

Susumu Kitagawa, Richard Robson and Omar Yaghi pioneered the creation of metal-organic frameworks, which can capture and store molecules such as carbon dioxide.

The Nobel Prize in Physics 2025 was awarded to John Clarke, Michel H. Devoret and John M. Martinis "for the discovery of macroscopic quantum mechanical ...

In 1985, experiments revealed the quantum behaviour of a macroscopic degree of freedom: the phase difference across a Josephson junction. The authors recount the history of this milestone for the development of superconducting quantum circuits.

John Clarke, Michel Devoret and John Martinis discovered quantum physics on a macroscopic scale, paving the way for quantum computing.

She was a tireless advocate for conservation, the welfare of captive chimpanzees and the protection of habitats.

This study of 89 multinational firms finds no significant link between voluntarily offsetting emissions and decarbonization speed. Firms spend little funds on carbon credits, and emission offsetting is not a central part of their climate strategies.

The 2025 Nobel Prize in Physiology or Medicine has been awarded jointly to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi “for their discoveries ...
