This prespecified updated survival and exploratory subgroup efficacy analysis of the phase 3 DESTINY-Breast04 trial shows that trastuzumab deruxtecan treatment in patients with HER2-low metastatic breast cancer leads to continuous survival benefit irrespective of estrogen receptor or hormone receptor status.

Analysis combining multiple global tree databases reveals that whether a location is invaded by non-native tree species depends on anthropogenic factors, but the severity of the invasion depends on the native species diversity.

This study presents FolTAC-dual, a folate receptor-mediated platform for dual degradation of EGFR/HER2 and PD-L1/VISTA, offering a strategy to overcome drug resistance and enhance antitumor immunity for cancer treatment.

Lo and colleagues report that double-positive thymocytes from neonates express less Zap70 and show reduced Ca^2⁺/NFAT signaling compared to double-positive thymocytes from older thymi. This diminished Ca^2⁺ signaling alters negative selection for self-reactive TCRs, resulting in a cell-intrinsic temporal window for regulatory T versus conventional T cell development in the thymus.

Electrochemical CO_x reduction to multi-carbon products is hindered by low energy efficiency, in part due to sluggish ion transport across charge-selective membranes used in electrolysers. Here the authors use a porous, non-charge-selective separator that enhances ion transport and improves performance for CO electrolysis.

Distal mutations, though far from the active site, enhance Kemp eliminase catalysis by tuning conformational dynamics that facilitate substrate binding and product release, thereby promoting the full catalytic cycle.

Monocyte-derived macrophages (MDMs) infiltrate the brain after traumatic brain injury (TBI) and contribute to cognitive deficits. Here, the authors show that MDMs persist long-term in the brain after TBI and acquire a disease- and age-associated signature enriched in human TBI and AD brains.

Microplastics are found in the environment globally, but their atmospheric transport is not well understood. Here the authors report atmospheric microplastic pollution at the Pic du Midi Observatory, suggesting free long range transport in the troposphere.

A complementary analysis of DESI DR2 distance measurements along with supernova and CMB data shows consistent, moderate evidence that dark energy changes over time rather than behaving as a simple cosmological constant.

Li, He, Liu and colleagues characterize the dynamic bivalent chromatin landscape during mouse peri-implantation development. They find that factor ZBTB17 works with KDM6A/B to resolve transiently maintained bivalent domains and prime gene activation.

Stress urinary incontinence (SUI) is a significant clinical challenge where less invasive treatment strategies that also address the pathophysiology of SUI are desirable. Here, Fang et al. engineer an injectable, thermo-responsive composite hydrogel incorporated with programmed stem cells that provides structural support to the atrophic urethral sphincter and promotes urethral sphincter regeneration, angiogenesis, and neurogenesis as a treatment strategy for SUI.

Ozone-depleting substances have been controlled by the 1987 Montreal Protocol, ensuring atmospheric concentrations are now in decline. Here, the authors use a 3D model and suggest that these controls have already had significant benefits, with much larger ozone depletion than previously thought avoided by the protocol.

Although ice plays a crucial role in shaping our ecosphere, its microstructures formed by freezing water remain unclear. Here, the authors employ cryogenic liquid-cell TEM to gain atomic-level insights into ice defects frozen from liquid water.

Variation in responses to bacterial and viral stimuli between Batwa rainforest hunter-gatherers and Bakiga agriculturalists from Uganda suggests population-level divergence under natural selection, with hunter-gatherers disproportionately showing signatures of positive selection.

Using a combination of radical retrosynthesis, biocatalysis and C–H functionalization logic, a concise and scalable approach to the synthesis of saxitoxin and derivatives thereof in fewer than ten steps is presented.

Proximity-ligation-based sequencing from 111 samples and 5 environments reveals that a substantial proportion of phages infect multiple species.

CSF total tau (t-tau), often used as a marker of neuronal damage, is more strongly linked to synaptic degeneration. Here, the authors show that t-tau better reflects synaptic dysfunction than axonal or neuronal loss in Alzheimer’s disease.

TBK1 mutations are linked to Amyotrophic Lateral Sclerosis (ALS) and Fronto-temporal dementia (FTD), but their cell-type specific disease contributions are unclear. Here, the authors show that Tbk1 deletion from mouse microglia shifts them to an aged-like phenotype and causes social recognition deficits.

Nitrogen and phosphorus limitations are both key to spatial patterns and temporal trends in primary production. This global analysis indicates that phosphorus limitation on terrestrial primary productivity has become stronger and is increasing more rapidly than nitrogen limitation.
