Although river protection is core to social and environmental well-being, the extent to which river conservation policies are effective is difficult to assess. This study reveals that, under all relevant protection mechanisms in the contiguous USA, only 12% of rivers are adequately protected.

Neri et al. develop elegant tools to understand how the sympathetic nervous system regulates intrascapular brown adipose tissue (iBAT) function. Using these tools, they find that sympathetic nerves targeting the iBAT parenchyma control local blood flow and heat production, while those innervating the iBAT vasculature regulate systemic glucose metabolism.

Brown adipose tissue (BAT) is key for metabolic balance. Here, the authors show that RAP250 deficiency enhances BAT activity. Under these conditions, BAT-derived neuritin-1 regulates thermogenesis and fat metabolism, showing therapeutic promise for obesity and metabolic disorders.

González-Gualda, Reinius et al. demonstrate that platinum-based chemotherapy-induced senescence promotes malignancy in ovarian and lung cancer via TGFβ ligands, with evidence in mouse models validated in clinical samples. Concomitantly blocking TGFβ signaling with chemotherapy reduces tumor burden and increases survival in mice.

Omnivores like bears can switch between plant and animal diets, potentially helping them respond to changing conditions. By combining modern and fossil data, this study shows that bears shift toward carnivory in harsher climates and toward herbivory in more productive environments.

CLPP-deficiency-driven mitochondrial dysfunction in brown adipose tissue leads to the accumulation of d-2-hydroxyglutarate, in turn promoting lipid-droplet enlargement by altering gene expression and epigenetically regulating nuclear stiffness.

Mangrove ecosystems are facing severe climate threats. However, this study shows that strategically expanding protected areas to include the most climate-resilient sites can safeguard biodiversity and ecosystem services for the future, and this can be achieved with only a modest increase in protected area.

Inhibition of haem synthesis is shown to lead to the accumulation of branched-chain amino acids in the brown adipose tissue of mice, which reduces UCP1 levels and impairs thermogenesis.

The ZFTA–RELA fusion, an oncogene for ependymomas, promotes the production of itaconate, and its dependence on this metabolite represents a new therapeutic target for this cancer.

GDF15 has been associated with cancer-associated cachexia. Here, the authors show that STK11/LKB1 loss-of-function mutations in non-small cell lung cancer result in an exaggerated integrated stress response culminating in the tumor cell secretion of the cytokine GDF15 promoting cachexia.

The hepatitis B virus surface protein recognizes host entry receptor via its intrinsically disordered peptide. The authors reveal the dynamic process of the viral surface protein that involves a stepwise binding maturation for establishing high affinity and specific virus-receptor entry complex.

Using infant fMRI, the authors show that, by 2 months of age, representations in high-level visual cortex encode visual categories that align with deep neural networks, and lateral object-selective regions are later to develop.

Coherent spin waves—quantized into magnons—can be emitted as Cherenkov radiation, but their experimental realization is hindered by the lack of fast-moving magnetic perturbations. Now, a picosecond strain pulse is shown to induce this effect.

Proxy records from Lake Baikal show that rapid cooling coincided with Northern Hemisphere ice sheet expansion 2.7 million years ago, a change accompanied by a transition to open steppe ecosystems.

Individual dietary specialization is impacted by development, social learning, genetics, and environment. Here, the authors document European brown bear diet in a multigenerational female sample, finding that social learning during rearing was the most important contributor to dietary specialization.

Brown dwarfs are small stars that are believed to be made of a warm dense plasma that cannot support hydrogen fusion as larger stars do. Here, the authors present a method for studying the properties, such as resistivity, of warm dense plasmas in the laboratory.

Stone tools illustrate behavioural complexities in Middle Pleistocene hominin populations. Here, the authors present small dimensional flakes and hafted tools from Xigou, central China, dated to ~160–72 thousand years ago that demonstrate early, complex technological advancements.

Johnson et al. link ARIA, a complication of anti-amyloid therapy, to clonal expansion of cytotoxic CD8 + T cells with glycolytic reprogramming and vascular trafficking potential, with implications for biomarker development and risk mitigation.

The effects of interactions on Hanbury Brown and Twiss interferometry are studied by considering the propagation of light in a nonlinear optical medium. The interactions affect the multipath interference, which makes it difficult to extract information about the light source. Nevertheless, the recovery of the disordered information is demonstrated through proper analysis.

Korobkina et al. show that ACLY in brown fat prevents metabolic overload in the tricarboxylic acid cycle, thus ensuring adequate thermogenesis by avoiding cellular stress.

Aortic aneurysm and dissection are lethal vascular diseases lacking effective medical therapy. Here the authors show that calcium channel blocker use increases AAD risk, worsens disease progression in models and patients, and may impair post-repair outcomes, warranting caution in at-risk hypertension.

Engineered mucus-tethering bispecific nanobodies neutralize and entrap viruses to enhance mucosal immunity, preventing influenza infection and limiting SARS-CoV-2 transmission.

Large-effect variants in autism remain elusive. Here, the authors use long-read sequencing to assemble phased genomes for 189 individuals, identifying pathogenic variants in TBL1XR1, MECP2, and SYNGAP1, plus nine candidate structural variants missed by short-read methods.

In humans, conception during cold seasons is shown to exhibit higher brown adipose tissue activity and adaptive thermogenesis, and lower body mass index and visceral fat accumulation in the offspring.

The authors consider the changing sensitivity of the leaf-onset date to temperature (S_T) for boreal deciduous broadleaf forests. S_T increased between 1982–1996 and 1998–2012—potentially linked to enhanced chilling accumulation—but this increase is underestimated in phenology models.

N6 - methyladenosine (m6 A) is a prevalent and abundant mRNA modification, yet its cell-type specific roles remains unclear. Here, the authors show that m6 A modification differentially regulates the transcriptomes of brown and white adipose tissue, resulting in distinct impacts on systemic metabolism.

Sweat sensors are important in personalized healthcare using natural oxidase to target biomolecules but these reactions are susceptible to external interference. Here, the authors report tryptophan- and histidine-treated copper metal-organic frameworks which show highly selective activity for ascorbate oxidation and can serve as an efficient ascorbate oxidase-mimicking material in sensitive sweat sensors.
