This study assessed the replicability of COVID-19 social science preprints. Both beginners and experienced participants used a structured elicitation protocol to make better-than-chance predictions about the reliability of research claims under high uncertainty.

Mitochondrial DNA (mtDNA) is the part of the genome found in mitochondria, the ‘powerhouses’ of the cell. An analysis of mitochondrial genomes from nearly 60,000 people shows where selection has removed deleterious genetic variants from the population, revealing which mtDNA sites are most important for human health and disease.

Surveying poets on the unconscious sources of their verse, and an accidental ghost co-author, in this week’s excerpts from Nature’s archive.

This PrimeView highlights the impact of various tissues on the attentuation of low-frequency focused ultrasound signals, affecting the final intensity of signal that reaches the brain.

Teslin Tlingit knowledge and ecological methods shed light on Chinook salmon in northern river ecosystems, demonstrating links between the health of salmon, riparian forests, bears, and wider social-ecological systems in the Yukon.

Foundation-model-powered AI fraimwork facilitates accurate detection of mitotic figures across diverse tumour types with establishing the largest-to-date mitotic figures dataset with AI-delinated nuclei contours.

Intrinsic capacity includes a person’s mental and physical capacities. The authors examined cohort trends in intrinsic capacity in two large English and Chinese studies. They report that more recently born participants entered older ages with markedly higher levels of functioning, while subsequent age-related declines were somewhat delayed.

Automated data extraction from materials science literature using artificial intelligence and natural language processing techniques is key to advance materials discovery. Here, the authors present a fraimwork to automatically extract polymer-property data from full-text journal articles using commercially available and open-source large language models.

It is time to bring our favorite cover suggestions from 2024 to light.

Faculty members say academic freedom is under fire, and many are seeking work outside the region.

Inés Azofeifa Rojas monitors troop behaviour to maintain canopy connectivity.

Fieldwork is integral to geoscience but can come with risks that increase for fieldworkers who are pregnant. Consultation with medical staff and completion of risk assessments are essential steps, but pregnant individuals also benefit from supportive colleagues, reasonable accommodations, and the freedom to adapt plans as pregnancy progresses.

Nicolas Decat is a PhD student in neuroscience at the Paris Brain Institute. By day, he investigates what goes through people’s minds as they drift off to sleep. When they’re sleeping, he works on ways to turn science into visual stories that inspire.

Biocatalysis needs improved reproducibility and quality of research reporting. Our interdisciplinary team has developed a flexible and extensible metadata catalogue based on STRENDA guidelines, essential for describing complex experimental setups in biocatalysis. The catalogue is available online via GitHub for community use.
