Global Burden of Disease estimates show that between 1990 and 2023, the prevalence and burden of drug use disorders, inclusive of amphetamine, cannabis, cocaine and opioid use, have been increasing in high-income countries, particularly in the USA.

Estimates from the Global Burden of Disease study reveal declines in chronic respiratory disease mortality between 1990 and 2023—especially during the COVID-19 pandemic—but the burdens on people affected remain substantial.

Coral reefs have been severely affected by anthropogenic stress. Using long term data from the Great Barrier Reef, this study found temporal changes in the latitudinal diversity gradient, and stronger correlations between coral assemblage changes and fish diversity than with coral cover fluctuations.

In this work, Urem et al. characterize the mode of action as well as mechanism of reduced susceptibility related to a class of antimicrobials that is in development for the treatment of infections with Gram-positive pathogens.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

Whole-genome sequencing, transcriptome-wide association and fine-mapping analyses in over 7,000 individuals with critical COVID-19 are used to identify 16 independent variants that are associated with severe illness in COVID-19.

Systematic analysis from the Global Burden of Disease study reported that, despite global improvements from 1990 to 2021, dietary iron deficiency-associated disease burden remains high in women, children and residents in low socio-demographic index countries.

Observations of optical flares from AT2022tsd (the ‘Tasmanian Devil’) show that they have durations on the timescale of minutes, occur over a period of months, are highly energetic, are probably nonthermal and have supernova luminosities.

Agricultural runoff adds sulfate to Florida wetlands, which increases production of toxic methylmercury at moderate sulfate concentrations that is assimilated in fish. The study helps predict wetland responses to management and climate variables.

Autophagy in CD11c⁺ phagocytes prevents myeloid-derived suppressor cell recruitment and promotes protective T cell responses during high-dose Mycobacterium tuberculosis infection in mice.

Qiu et al. provide insight into the metabolic adaptations that enable breast cancer cells to proliferate in the face of glutaminolysis blockade.

Biomphalaria glabrata is a fresh water snail that acts as a host for trematode Schistosoma mansoni that causes intestinal infection in human. This work describes the genome and transcriptome analyses from 12 different tissues of B glabrata, and identify genes for snail behavior and evolution.

The study develops a machine learning approach for predicting bone regeneration in an additively manufactured bioceramic scaffold, which is correlated with an in vivo sheep model, exhibiting effectiveness for solving such a multiscale modeling problem.

A genome-wide association study of critically ill patients with COVID-19 identifies genetic signals that relate to important host antiviral defence mechanisms and mediators of inflammatory organ damage that may be targeted by repurposing drug treatments.

Glycolytic enzymes are challenging drug targets due to their highly conserved active sites and phosphorylated substrates. Here, the authors identify fast acting allosteric inhibitors of Trypanosoma brucei phosphofructokinase that block trypanosome glycolysis and provide cure evidence in murine model.

New antimalarials are urgently needed. Here, the authors identify Open Source Malaria compound, OSMS-106, as a reaction hijacking inhibitor of the malaria parasite protein synthesis machinery, with potential use for treatment and prophylaxis.

Single-nucleus RNA sequencing in a mouse model of Aβ accumulation and postmortem brain tissue from people with Alzheimer’s disease reveals substantial species-specific differences in transcriptional signatures, but both point to the contribution of glia and the importance of TREM2.

Many gene-regulatory proteins have been shown to activate in pulses, but whether cells exploit the dynamic interaction between pulses of different regulatory proteins has remained unexplored; here single-cell videos show that yeast cells modulate the relative timing between the pulsatile transcription factors Msn2 and Mig1—a gene activator and a repressor, respectively—to control the expression of target genes in response to diverse environmental conditions.

Autoimmunity is triggered by trafficking of self-reactive T cells into tissues. Joonsoo Kang and colleagues show that the kinase ITK regulates T cell trafficking. ITK inhibition or genetic ablation prevents homing of autoreactive T cells into tissues and reduces islet destruction in models of type 1 diabetes without affecting T cell activation or antiviral T cell responses, suggesting that this kinase may be targeted in autoimmune disease.

Creating laboratory-grown bone for implantation into injury sites is an aim of regenerative medicine. However, newly grown bone may not have the same structural and compositional properties as native bone. Materials characterization shows that the source of cells for the new bone growth has a significant effect on its properties.

The authors developed a platform for rapid identification of interacting plant immune receptors and pathogen avirulence proteins by library screening in protoplasts, then used it to identify new wheat stem rust Avr genes recognized by known wheat resistance genes.

The mechanisms of PARP inhibitor (PARPi) resistance are poorly understood. Here the authors employ a CRISPR mutagenesis approach to identify PARP1 mutants causing PARPi resistance and find that PARP1 mutations are tolerated in BRCA1 mutated cells, suggesting alternative resistance mechanisms.

Non-alcoholic fatty liver disease (NAFLD) is a potentially serious liver disease with a substantial burden worldwide. In this Consensus Statement, a global multidisciplinary group of experts develop consensus statements and recommendations addressing a broad range of topics on NAFLD to raise awareness and spur action.
