Saying ‘no’ to this kind of visual content is a question of research integrity, consent, privacy and intellectual-property protection.

Most US wetlands just lost federal protection, but there’s still time for state and local governments to act. Scientists and the public can help.

Astrophysicist who researched galactic structure and star formation.

Finding time and space to grieve for a partner, child or friend can be complicated for researchers — and the peers who support them.

Although powerful, the tools are not as intelligent as they seem. Use them with caution, computer scientists warn.

Lucas van der Zee hopes to restore current farmland to its natural state by eliminating the vegetation stage of crop-growing.

The cultivation of oil palm is here to stay. However, a five-year study indicates that creating islands of native trees within oil-palm monocultures increases biodiversity and ecosystem functioning without notably lowering crop yields.

Deep reinforcement learning has been used to improve computer code by treating the task as a game — with no special knowledge needed on the part of the player. The result has already worked its way into countless programs.

A fatty acid in the milk of nursing mice has been found to trigger a transformation in the metabolic pathways that are active in pups’ heart muscle cells, enabling the cells to rapidly mature after birth.

Fifty years ago, an equation called the Black–Scholes formula revolutionized finance, leading to a rapid growth of markets and stimulating quantitatively oriented minds. But, with time, its simplicity became a liability — and yet its legacy persists.

Analysis of people’s web searches and visited websites suggests that it is more likely that they are choosing to engage with partisan or unreliable news than that they are being unduly exposed to it by search-engine algorithms.

The development of a promising type of battery has been plagued by an issue that causes these devices to fail — lithium filaments grow in the electrolyte. An investigation of this failure mechanism could help to solve the problem.

The authors report observational evidence that, within interstellar gas, there are temperature inhomogeneities affecting only highly ionized gas and causing the abundance discrepancy problem, and provide new empirical relations for estimation of temperature and metallicity.

Measurements of fast solar wind streams from the Parker Solar Probe spacecraft provide strong evidence for the interchange reconnection mechanism being responsible for accelerating the fast solar wind.

 Artificial intelligence goes beyond the current state of the art by discovering unknown, faster sorting algorithms as a single-player game using a deep reinforcement learning agent. These algorithms are now used in the standard C++ sort library.

A unitary protocol for braiding projective non-Abelian Ising anyons in a generalized stabilizer code is implemented on a superconducting processor, allowing for verification of their fusion rules and realization of their exchange statistics.

Experiments at the National Ignition Facility show how delocalization of K-shell electrons is driven by extreme pressure and temperature.

Petahertz-scale optical-field metrology in a pump-probe setting enables the direct observation of how the optical properties of a medium evolve after 1-fs-scale photoinjection.

Lithographically patterned perovskite nanocrystal arrays were used to determine radiation vectors from X-rays to visible light and the emission colours of the nanoparticles was used to create images of three-dimensional objects and for phase-contrast imaging.

Analysis of dendrite initiation, owing to filling of pores with lithium by means of microcracks, and propagation, caused by wedge opening, shows that there are two separate processes during dendrite failure of lithium metal solid-state batteries.

The chemoselective and enantioconvergent N-alkylation of aliphatic amines, including ammonia, is achieved using chiral tridentate anionic ligands and a copper catalyst; the method shows excellent enantioselectivity and functional-group tolerance.

The enantioconvergent alkylation of oxygen nucleophiles is achieved using α-haloamides and a readily available copper catalyst, and the reaction proceeds under mild conditions in the presence of a wide variety of functional groups.

Data-assimilated three-dimensional dynamic rupture models of the 2019 Ridgecrest earthquake sequence in California are used to reveal the dynamics, interactions and delays of the earthquake sequence.

A large-scale, five-year study in Indonesia finds that enriching oil palm-dominated landscapes with patches of trees bolsters biodiversity and ecosystem functioning without impairing oil palm yields but should not replace forest protection.

The high global temperatures of the Eocene and subsequent habitat reconfigurations might have been critical for the rise and retention of the highly productive, high-turnover fish faunas that characterize modern coral reef ecosystems.

A non-destructive DNA isolation method for the stepwise release of DNA trapped in ancient tooth and bone artefacts is developed.

The genomic differences between primary and metastatic tumours are assessed across 23 cancer types using pan-cancer whole-genome analysis.

Ecologically valid data collected during the 2018 and 2020 US elections show that exposure to and engagement with partisan or unreliable news on Google Search are driven not primarily by algorithmic curation but by users’ own choices.

Mouse models show that myelin dysfunction and associated inflammation increase with age, which can promote amyloid-β deposition and therefore risk of developing Alzheimer’s disease.

A study examining bacterial gene expression in human-derived samples identifies a gene encoding a small RNA and describes how it orchestrates the transition between chronic and acute infection in Pseudomonas aeruginosa.

The switch from glucose- to fatty acid-dependent metabolism in cardiomyocytes of newborn mice is governed by γ-linolenic acid in maternal milk, which binds to retinoid X receptors, thereby causing a transcription-dependent metabolic transition.

Remote tumours cause liver dysfunction by releasing extracellular vesicles and particles containing palmitic acid, which induces TNF signalling in Kupffer cells, resulting in inflammation, fatty deposits and metabolic dysregulation, thus both reducing the efficacy and increasing the toxicity of chemotherapies.

We model occult preneoplasia by biallelic inactivation of TP53, a common early event in gastric cancer, in human gastric organoids, the results implying predictability in the earliest stages of tumorigenesis.

Ubiquitination of the receptor FAM134B regulates ER-phagy and remodelling of the endoplasmic reticulum in response to cellular demands.

The membrane-shaping protein ARL6IP1 is involved in the selective degradation of the endoplasmic reticulum, and this process depends on its ubiquitination and interaction with other membrane-shaping proteins such as FAM134B.

We report the cryo-electron microscopy structure of native pre-60S particles trapped in the channel of the yeast nuclear pore complex, suggesting a translocation model for the export of pre-60S particles through the complex.
