Scientists disrupt less but more persistently with career aging.

Disruption describes the extent to which a scientific work overturns the prior knowledge on which it builds and leads to a new line of research. A scientist's tendency to produce disruptive work has been found recently to decline over the career. However, the disruption index captures only how strongly a paper overturns prior work and ignores whether that disruption is later accepted or overturned by subsequent research.

Disruption describes the extent to which a scientific work overturns the prior knowledge on which it builds and leads to a new line of research. A scientist's tendency to produce disruptive work has been found recently to decline over the career. However, the disruption index captures only how strongly a paper overturns prior work and ignores whether that disruption is later accepted or overturned by subsequent research. The persistent disruption (PD) framework adds this second perspective, identifying work that disrupts prior research and is then consolidated rather than displaced by later work. We examine how PD evolves over the career and find the opposite pattern: The probability of producing a persistent disruptive paper increases with career age. Senior scientists disrupt prior work less often compared to young, but once they do, the disruption tends to persist rather than being quickly superseded. Our results suggest that this reversal feature is due to the experience and we corroborate it across several dimensions of recognition. We also show that, at a fixed level of disruptiveness, the more senior the scientist is, it attracts more citations, social-media attention, and research grants. Nobel laureates also show delayed persistent disruptions. They exhibit high disruptive ability early in their careers, yet their prize-winning work appears years later. This lag further indicates that experience is needed to turn disruptive ability into the field's most celebrated contributions.

Historical trends show more declining than increasing species among European pollinators.

Anthropogenic global change presents a growing threat to insect pollinators. Yet, long-term, continental-scale assessments of their population trends remain limited. Here, we leveraged a curated database of over four million occurrence records, covering 88% of extant bee and hoverfly species in Europe, to assess persistence, richness, and occupancy trends over the past century. Species persistence at the European level was relatively high, with modern records available for 87% of bee and 89% of

Extensive glacier loss in the coterminous United States.

Glaciers populate the mountain ranges of the western conterminous United States and despite their importance to alpine hydrology, their area and volume change have never been comprehensively evaluated. Our study shows that since the mid-twentieth century about one-quarter of the glaciers have disappeared and the overall area and volume are reduced by one-third. The pattern of glacier shrinkage suggests most glaciers in the conterminous United States are largely maintained by local topographic in

Geography of groundwater use and depletion in internationally shared aquifers.

Transboundary aquifers (TBAs) underlie 35% of global groundwater-irrigated cropland, yet few are covered by formal cooperative arrangements. Whether this limited cooperation is consequential depends in part on where groundwater is used within shared aquifers, because pumping far from international borders may generate little cross-border impact. Combining [Formula: see text]116,000 well observations with global irrigation data across all 426 known TBAs, we assess how groundwater use and depletio

Reaction-based cryo-EM resolves the continuous conformational spectrum of CTP synthase catalysis.

Capturing enzymes under native turnover conditions remains a grand challenge in structural biology. Here, we develop a reaction-based cryo-electron microscopy (cryo-EM) strategy that directly samples Drosophila melanogaster cytidine triphosphate synthase (CTPS) from actively catalyzing mixtures containing only natural substrates and allosteric effectors. By integrating reaction-based sampling with three-dimensional variability analysis, we resolve a continuous conformational spectrum of CTPS dur

GTP orchestrates CTP synthase via an allosteric effector-cycling mechanism.

Cytidine triphosphate (CTP), a fundamental building block of RNA, plays vital roles in diverse biological processes. CTP synthase (CTPS) is the only known enzyme for de novo synthesis of CTP. Efficient CTPS catalysis requires guanosine triphosphate (GTP) in a dose-dependent, nonconsumptive manner; however, the precise mechanism by which GTP drives CTP formation remains unclear. Here, we integrate a series of cryo-EM structures of Drosophila melanogaster CTPS captured from actively catalyzing sam
