Human impacts on global freshwater fish biodiversity

Freshwater fish represent one-fourth of the world's vertebrates and provide irreplaceable goods and services but are increasingly affected by human activities. A new index, Cumulative Change in Biodiversity Facets, revealed marked changes in biodiversity in >50% of the world's rivers covering >40% of the world's continental surface and >37% of the world's river length, whereas

Cholangiocyte organoids can repair bile ducts after transplantation in the human liver

Organoid technology holds great promise for regenerative medicine but has not yet been applied to humans. We address this challenge using cholangiocyte organoids in the context of cholangiopathies, which represent a key reason for liver transplantation. Using single-cell RNA sequencing, we show that primary human cholangiocytes display transcriptional diversity that is lost in organoid culture. H

Mechanism of membrane-tethered mitochondrial protein synthesis

Mitochondrial ribosomes (mitoribosomes) are tethered to the mitochondrial inner membrane to facilitate the cotranslational membrane insertion of the synthesized proteins. We report cryo–electron microscopy structures of human mitoribosomes with nascent polypeptide, bound to the insertase oxidase assembly 1–like (OXA1L) through three distinct contact sites. OXA1L binding is correlated with a serie

Prospective mapping of viral mutations that escape antibodies used to treat COVID-19

Antibodies are a potential therapy for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but the risk of the virus evolving to escape them remains unclear.

Clinically relevant mutations in core metabolic genes confer antibiotic resistance

Although metabolism plays an active role in antibiotic lethality, antibiotic resistance is generally associated with drug target modification, enzymatic inactivation, and/or transport rather than metabolic processes.

Microbial single-cell RNA sequencing by split-pool barcoding

Single-cell RNA sequencing (scRNA-seq) has become an essential tool for characterizing gene expression in eukaryotes, but current methods are incompatible with bacteria.

Recurrent evolution of vertebrate transcription factors by transposase capture

Genes with novel cellular functions may evolve through exon shuffling, which can assemble novel protein architectures.

De novo design of transmembrane {beta} barrels

Cryptomeria japonica, or the Japanese cedar, is highly revered as the national tree of Japan. Locally known as 'sugi,' it covers over 4.5 million hectares of land, accounting for nearly half of Japan's artificial forests. However, it is also notorious for causing hay fever, with a good 26.5% of Japan's population reporting cedar pollen allergies in 2008. Over the past years, pollen allergy caused

Lithium-ion (Li-ion) batteries are the most common solutions that dominate the global market and are a huge problem due to their insufficient recovery.

How can researchers quickly access complex molecules for drug discovery?

The function of molecules used in drugs in part depends on their structure, including the many chemical bonds between their atoms. These molecules can be built through several different chemical reactions, most of which are slow and inefficient because they rely on the formation of one chemical bond at a time.

Under pressure: Hydrogel swelling in a granular medium

Hydrogels hold promise in agriculture as reservoirs of water in dry soil, potentially alleviating the burden of irrigation. However, confinement in soil can markedly reduce the ability of hydrogels to absorb water and swell, limiting their widespread adoption. Unfortunately, the underlying reason remains unknown. By directly visualizing the swelling of hydrogels confined in three-dimensional gran

Prostaglandin E2 promotes intestinal inflammation via inhibiting microbiota-dependent regulatory T cells

The gut microbiota fundamentally regulates intestinal homeostasis and disease partially through mechanisms that involve modulation of regulatory T cells (T regs ), yet how the microbiota-T reg cross-talk is physiologically controlled is incompletely defined.

From measurements performed with ExoMars/NOMAD, we observe marked and rapid variability of the D/H along altitude on Mars and across the whole planet. The observations (from April 2018 to April 2019) sample a broad range of events on Mars, including a global dust storm, th
