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.…
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.…
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.…
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…
The development of large-scale, high-fidelity quantum processors is a fundamental scientific challenge, essential for exploring the boundaries of classical computation and advancing towards fault-tolerant systems.…
Controlling individual atoms using lasers1, ion traps2 and scanning probe tips3 has transformed our understanding of matter and enabled breakthroughs in quantum science4–6.…
The capacity of hippocampal circuits to transform inputs into downstream outputs is fundamental to navigation and memory, yet the circuit-level mechanisms that enable this flexibility in adapting to experience remain unclear.…
Liquid crystalline droplets with molecularly crowded interiors capable of selective biomolecular sequestration and interfacial wetting have been recently developed for the construction of artificial cells (protocells) and chain-like protocell networks1–3.…
The cerebral cortex shows species-specific variations in size and organization, which probably account for distinct behavioural abilities1. These structural differences may reflect evolutionary changes in the developmental expression of shared genes.…
Learning by imitation is the foundation for verbal and musical expression, but its neural basis remains unclear. A juvenile male zebra finch imitates the multisyllabic song of an adult tutor in a process that depends on a song-specialized cortico-basal…
Pregnancy poses many challenges, including protecting against infection and increased nutritional demands. Pregnancy-associated gut changes offer some help.…
When the concept of ‘click’ chemistry — highly effective and specific reactions — was first reported, some dismissed it as a gimmick. But it has transformed many fields of research.…
