Ultraviolet (UV) absorbents and industrial antioxidants are contaminants of emerging concern (CECs), but little is known about their distribution in Arctic wildlife, as well as how these contaminants vary over time, across regions, and between species. We used archived egg samples to examine the temporal patterns of 26 UV absorbents and industrial antioxidants in three seabird species (black-legged

Disease outbreaks, skin lesions, mortality events, and reproductive abnormalities have been observed in wild populations of centrarchids. The presence of estrogenic endocrine disrupting compounds (EEDCs) has been implicated as a potential causal factor for these effects. The effects of prior EEDC exposure on immune response were examined in juvenile largemouth bass (Micropterus salmoides) exposed to

The rapid development of nanomaterials (NMs) and the emergence of new multicomponent NMs will inevitably lead to simultaneous exposure of organisms to multiple engineered nanoparticles (ENPs) at varying exposure levels. Understanding the joint impacts of multiple ENPs and predicting the toxicity of mixtures of ENPs are therefore evidently of importance. We reviewed the toxicity of mixtures of ENPs

The United Kingdom and Italy need to renew their commitments to banish these major infectious killers from the world.

Evidence is building that the Northern Hemisphere is on course for a surge of COVID-19 cases this autumn and winter. Plus, a Nobel prize for ‘spooky’ quantum entanglement, and a call to reward research for being useful — not just flashy.

To mark the launch of Nature’s 2022 #ScientistAtWork photo competition, three experts offer tips on how to best capture your science on camera.

Massive SARS-CoV-2 sequencing project in Africa brings global benefits.

Reduced availability of agricultural water has spurred increased interest in using recycled irrigation water for U.S. food crop production. However, there are significant knowledge gaps concerning the microbiological quality of these water sources. To address these gaps, we used 16S rRNA gene and metagenomic sequencing to characterize taxonomic and functional variations (e.g., antimicrobial resistance)

With reference to the original article, there was an error in SI Table S9 in the data for only the Wood Rocket cookstove. The table has been corrected. SI Table SS5 has been added with data on cooking power that should have been included in the article. Subsequent SI tables have been renumbered, so the first line on page 15338 should read, “...Tables SS6–SS32...” In the second paragraph on page 15339

The fate and transport of nanoparticles (NPs) in streams is critical for understanding their overall environmental impact. Using a unique field-scale stream at the Notre Dame-Linked Experimental Ecosystem Facility, we investigated the impact of biofilms and the presence of dissolved organic matter (DOM) on the transport of titanium dioxide (TiO2) NPs. Experimental breakthrough curves were analyzed
