A new class of AI models, called foundation models, has entered healthcare. Foundation models violate several basic principles of the standard machine learning paradigm for assessing reliability, making it necessary to rethink what guarantees are required to establish warranted trust in them.

Method could probe whether a key tenet of quantum mechanics applies to gravity, which has so far resisted quantum theory.

Mechanical engineer Legena Henry converts sargassum and rum-distillery waste water to produce sustainable natural gas for vehicles.

The code underlying the Nobel-prize-winning tool for modelling protein structures can now be downloaded by academics.

At small or minority-serving institutions, time and resources that are needed to draft successful grant proposals are often in short supply. But help is available.

From maps of the stars to the multiverse, four enlightening art shows reveal diverse impressions of the cosmos.

Circular RNAs are prevalent, mysterious and fascinating, but their study requires great care.

Remains recovered from plaster casts of five people who died in the eruption of Mount Vesuvius have overturned some old assumptions about who they were. Plus, mitochondria can split into two different forms under stress.

The popularity of private planes, the distance covered by flights and associated greenhouse-gas production are all on the rise.

Some researchers seek to establish a single abnormal result on a set of biomarker-based tests as sufficient to diagnose the disease.

Samantha Harvey talks to Nature about her book Orbital

Donald Trump made numerous promises during his presidential campaign that could affect scientists and science policy. Will they be implemented once he is president?

A place to hide.

The treatment, given to four people with damaged corneas, seems safe but needs to be tested in larger trials.

Virologist Beata Halassy says self-treatment worked and was a positive experience — but researchers warn that it is not something others should try.

Norway offers up to 2 hours of paid time per day for breastfeeding. Why do other countries’ parental support policies lag so far behind?

The continuous evolution of SARS-CoV-2, particularly the emergence of BA.2.86/JN.1 lineage replacing XBB, necessitates re-evaluation of vaccine compositions 1–3. Here, we provide a comprehensive analysis of the humoral immune response to XBB and JN.1 human exposure. We demonstrate the antigenic distinctiveness of XBB and JN.1 lineages in SARS-CoV-2-naive individuals, and JN.1 infection elicits superior

Scientists raise the alarm following updated research ethics guidelines on heritable human genome editing.

The sex and ancestry of five people who died in the eruption are revealed by genetic material embedded in the casts.

Deciphering how mammals respond to sensations through their fur could inspire further research on skin sensitivity.

A satellite made of wood has been sent to the International Space Station, where it’ll later be released into orbit. Plus, we learn that snapshots of atomic nuclei smashing together can show us what shape they were.

Elderly big brown bats showed little sign of age-related degradation in the inner ear.

Physicist Mark Thomson will face several challenges — including bringing in enough money to build a colossal new particle-smashing ‘Higgs factory’.

The increasing popularity of Unmanned Aerial Vehicle (UAV) swarms is attributed to their ability to generate substantial returns for various industries at a low cost. Additionally, in the future landscape of wireless networks, UAV swarms can serve as airborne base stations, alleviating the scarcity of communication resources. However, UAV swarm networks are vulnerable to various security threats that

Analysis of billions of pages of results from searches using the Bing algorithm suggests that reliable sites appear in search results 19 to 45 times more often than do sites with low-quality content.

Mitochondria form two distinct subpopulations enabling them to produce essential cell components and energy, even under nutrient stress.
