Substance use disorder is a growing public health challenge in the United States. People who use drugs may be more vulnerable to ambient heat due to the effects of drugs on thermoregulation and their risk environment. There have been limited population-based studies of ambient temperature and drug-related morbidity. We examined short-term associations between daily ambient temperature and emergency

Background Non-alcoholic fatty liver disease (NAFLD) has become the leading cause of chronic liver disease worldwide and the determinants driving its severity remain to be elucidated. Perfluoroalkyl substances (PFAS) are synthetic chemical compounds. They are used in commonplace products and persistent in water, soil and the human body. In vitro and animal studies suggest a pathogenic role for PFAS

Food contact materials (FCMs) and food contact articles are ubiquitous in today’s globalized food system. Chemicals migrate from FCMs into foodstuffs, so called food contact chemicals (FCCs), but current regulatory requirements do not sufficiently protect public health from hazardous FCCs because only individual substances used to make FCMs are tested and mostly only for genotoxicity while endocrine

Background Future warming is projected to increase the heat-related mortality burden, especially for vulnerable populations. However, most previous studies focused on non-accidental morbidity or mortality, with far less research on heat-related accidental events. Methods We collected individual accidental death records among all residents in Chinese mainland from June to August during 2013-2019. Accidental

Efforts to prevent infections and keep vulnerable people out of hospital are beginning to pay off, but deploying these strategies presents new challenges.

Emerging evidence suggests that pathogens can pair up to work together against immune system defences.

The consequences of respiratory syncytial virus infection sometimes linger for years — and scientists are trying to work out whether there’s a causal link.

A Nature survey finds that scientists are concerned, as well as excited, by the increasing use of artificial-intelligence tools in research.

Isolation can have lasting effects on the composition of microbes in the gut, but links to other health conditions are still poorly understood.

Drugs that counter RSV infection can safeguard newborns, offering another mode of protection alongside vaccines.

The invisible enemy.

A new Nature series will explore the many ways in which artificial intelligence is changing science — for better and for worse.

Why monitoring sewers could help to detect outbreaks, how RSV and flu viruses can couple together and other highlights.

Deceptive videos and images created using generative AI could sway elections, crash stock markets and ruin reputations. Researchers are developing methods to limit their harm.

Fractional quantum Hall effect in the absence of a magnetic field.

By surveilling respiratory syncytial virus, the World Health Organization is hoping to understand who the virus infects and the burden it has.

If deployed effectively and equitably, this latest generation of vaccines could help to prevent countless deaths and hospitalizations among the young and old.

Governments need to put remote communities at the forefront of strategies to prevent the respiratory disease.

Large language models and other artificial-intelligence systems could be excellent at synthesizing scientific evidence for policymakers — but only with appropriate safeguards and humans in the loop.

Christopher Reddy helped to quantify the Deepwater Horizon oil spill, a stressful experience that changed his view of what it means to be a well-rounded scientist and person.

Silicon (Si) anode with high theoretical specific capacity (3579 mAh g−1) offers great promise for realizing high-energy solid-state batteries (SSBs). However, given Si’s huge volume variations during cycling, sluggish kinetics and unfavorable interface stability with solid-state electrolyte (SSE), its practical potential in SSBs has not been fully exploited. Herein, we propose a design of highly-dense

With the rapid prosperity of the global electric vehicle market and increasing demand for the higher user experience of portable electronics, the development of high-performance lithium-ion batteries (LIBs) with fast-charging capability has become an inevitable trend. However, the utilization of mainstream graphite anodes in LIBs presents critical technological obstacles such as capacity degradation

MnOx@Fe3O4 bimetallic nanoparticles coated powdered activated carbon (MnOx@Fe3O4-PAC) was successfully synthesized by a two-step chemical co-precipitation method. A comprehensive analysis of MnOx@Fe3O4-PAC’s surface profile, crystal structure, and element composition were conducted to investigate its structural characteristics and oxytetracycline (OTC) removal mechanism. It was observed that MnOx@Fe3O4

Jellyfish have demonstrated that you don’t need a centralized nervous system to learn by association. Plus, scientists under attack in the United States and how a newly discovered type of stem cell attracts cancer cells to the spine.

As a promising pathway for sustainable desalination and wastewater treatment, thermally-localized solar evaporation has been successfully demonstrated, mainly with water or NaCl solution. However, the evaporated solution could vary a lot from these ideal choices in real applications, which could trigger the evaporation failure easily. Herein, we propose a solute-replacement strategy for solar evaporation

Lead-tin (Pb-Sn) perovskites are a highly promising composition for single-junction and all-perovskite tandem solar cells due to their narrower bandgap and reduced toxicity. While the use of quasi-two-dimensional (quasi-2D) Ruddlesden-Popper phases has resulted in superior stability towards the environment and large improvement in the crystallization with respect to the 3D compositions, very little

Nano-engineered oxides play a frontier role in the development of next-generation catalysts and microelectronics. Recently, metal exsolution from oxides has emerged as a promising nano-structuring tool to fabricate nanoparticle-decorated oxides. However, controlling the size, density, composition, and location of exsolved nanoparticles remains a challenge, limiting the ultimate performance achievable
