An old theory gains fresh support from advanced DNA sequencing, which can detect rare mutations in B cells from people with autoimmune thyroid conditions.…

Stacks of transistors built from nanomembranes that can be rolled onto a substrate have been used to fabricate 3D circuits. Stacks of transistors built from nanomembranes that can be rolled onto a substrate have been used to fabricate 3D circuits.

Massive analyses of RNA transcripts from rodents, monkeys and humans reveal hallmarks of ageing that could expedite the development of anti-ageing interventions.…

One in six Internet-using adolescents in parts of Africa and Asia faced technology-facilitated sexual abuse in 2020–21. As digital access expands globally, better protection is crucial.…

A large-scale experiment tested the impact of changing the Bluesky feed-ranking algorithm on political content and perceptions during the 2024 US presidential election.…

A fertilized egg’s first few divisions rely on proteins stored in fibrous structures. The ordered nature of these structures and clues about their function are revealed. A fertilized egg’s first few divisions rely on proteins stored in fibrous structures.…

Monolithic, three-dimensional (3D) integrated circuits promise advantages in packing density, energy consumption and interconnectivity bandwidth but require forming high-performance semiconductors and transistors on top tiers under the constraint of a…

When radiative thermal energy is exchanged at near field, evanescent surface waves such as surface phonon polaritons can tunnel through the gap, boosting heat transfer above the far-field blackbody limit by several orders of magnitude1,2.…

For the first time in history, civic discourse commonly occurs in digital environments in which algorithms influence exposure to social information1,2.…

Realistic quantum information processing devices are inherently imperfect, leading to computational errors that require quantum error correction.…

Many-body phenomena in quantum materials emerge from the interplay among a broad continuum of electronic states and controlling these interactions is critical for engineering new phases.…

The formation of the first stars and galaxies marked the onset of chemical enrichment, yet direct observations of such primordial systems remain elusive.…

Neurological symptoms after brain injury can remain as lifelong detrimental sequelae because most of the spontaneous recovery response disappears within a few months after the injury1,2.…

The ability of animals to efficiently track down and digest food is crucial for their survival, and the specialization to different diets is a major driver of diversification in this group1–3.…

Millions of people around the world query large language models (LLMs) for information. Although several studies have compellingly documented the persuasive potential of these models1–10, there is limited evidence of who or what influences the models…

Compound events—such as concurrent hot–wet and drought–heat extremes—are among the most consequential climate hazards on Earth1–4 and are projected to become more severe under warming.…

Homo erectus remains have been found in Africa, Eurasia and Southeast Asia1–3, dating back around two million years; however, owing to their age and state of preservation, obtaining informative molecular data from them has proved challenging.…

Wildfires are an escalating global hazard that threaten ecosystems, air quality and societies1,2. Although tall tropical mountains have generally been considered too cool and moist to burn3, the recent occurrence of high-elevation wildfires on…
