Sommaire :
In Depth - Radiocarbon dates revise histories of Indigenous societies New techniques challenge assumptions about Indigenous responses to European contact - Hunt for tree rings could yield Africa’s first drought atlas Records could reveal how much humanity has altered Sahel rains - A single gene helps rice handle the heat Discovery could preserve grain quality and yields as climate change raises temperatures - Tariff war takes toll on labs in China Scientists face higher prices and import bans on equipment and supplies - Ecologist blurred professional boundaries, report finds Thomas Crowther has lost his post at ETH Zürich but denies any misconduct - China reveals the foreign scientists who will share its rare lunar samples Seven research teams in six nations get Moon rocks and soil brought to Earth by the Chang’e-5 mission - NSF director resigns amid cuts to grants and staff reductions Sethuraman Panchanathan stepped down soon after Trump team started to terminate agency awards Feature - Tales from the crypt The lives of 17th century Milan’s working poor—their health, diet, and drug habits—emerge from thousands of bodies buried under a public hospital Commentary Expert Voices - The post-truth era and how science education keeps ignoring it Perspectives - The mechanics behind the beauty of roses As rose petals change shape during maturation, they do not follow classical geometrical incompatibility - Searching for partners Simplifying a three-dimensional search helps neurons find their targets - An uphill grind for wild plant populations Genetic variation is inadequate for the adaptation of a montane plant to new climates - A fungal ally wards off liver disease A metabolite secreted by an intestinal fungus blunts metabolic disease - Editing proteins inside a cell Pairs of split protein segments can modify a variety of target proteins in a living cell Policy Forum - Discovery research in physiologically maintained deceased Expanded research opportunities in deceased humans require ongoing ethical inquiry Letters - Benefits of onshoring forestry rely on science - China’s pet squirrel trade needs regulation - Deep-sea mining interests cannot shape research - NextGen Voices: Pursuing Science Abroad Research Articles - Metabolic signaling of ceramides through the FPR2 receptor inhibits adipocyte thermogenesis - A symbiotic filamentous gut fungus ameliorates MASH via a secondary metabolite–CerS6–ceramide axis - Intracellular protein editing enables incorporation of noncanonical residues in endogenous proteins - Interphase cell morphology defines the mode, symmetry, and outcome of mitosis - TIGR-Tas: A family of modular RNA-guided DNA-targeting systems in prokaryotes and their viruses - Electron collision in a two-path graphene interferometer - A self-regenerating Pt/Ge-MFI zeolite for propane dehydrogenation with high endurance - Coherent evolution of superexchange interaction in seconds-long optical clock spectroscopy - Universal distributed blind quantum computing with solid-state qubits - Formation of hydrided Pt-Ce-H sites in efficient, selective oxidation catalysts - Geometrically frustrated rose petals - Adaptation and gene flow are insufficient to rescue a montane plant under climate change - North American bird declines are greatest where species are most abundant - Dimensionality reduction simplifies synaptic partner matching in an olfactory circuit - Cryo-EM reveals mechanisms of natural RNA multivalency |

Efforts to address declines of North American birds have been constrained by limited availability of fine-scale information about population change. By using participatory science data from eBird, we estimated continental population change and r[...]
