The end-Permian mass extinction was linked with ocean acidification due to carbon degassing associated with Siberian Trap emplacement, according to boron isotopes from fossil shells and reconstruction of the carbon cycle. | Continue reading
Liver regeneration involves multiple cell types, including hepatocytes, hepatic stellate cells, endothelial cells and inflammatory cells. Recent studies have elucidated the interactions between these cells during regeneration as well as the mechanisms that regulate cell prolifera … | Continue reading
Reducing the use of scarce metals — and recycling them — will be key to the world’s transition to electric vehicles. | Continue reading
The detection of viruses by the immune system is mediated predominantly by the sensing of nucleic acids. Here, the authors review our current understanding of how this complex immune sensory system discriminates self from non-self nucleic acids to reliably detect pathogenic virus … | Continue reading

Fructose intake helps intestinal cells to survive hypoxic conditions. | Continue reading
Governments and companies urgently need to share data on the mounting volume of satellites and debris orbiting Earth. | Continue reading
Dramatic antibody production in people that were infected during the 2002–04 outbreak furthers hopes of a vaccine against many coronaviruses. | Continue reading
Small study hints that interference from bodies funding research into public-health issues such as nutrition and exercise may be more common than realized. | Continue reading
For the vast majority of people, COVID-19 vaccines are safe and effective. But further research is needed to understand the causes of rare adverse events. | Continue reading
Lineages that can evade immunity are spurring vaccine makers to explore ways to redesign their shots. | Continue reading
The drive to net zero has changed the calculus of the Promethean dream. | Continue reading
Pachyderms have extra copies of a key tumour-fighting gene. | Continue reading
Sharp wave-ripples from the hippocampus are shown to modulate peripheral glucose homeostasis in rats, offering insights into the mechanism that links sleep disruption and blood glucose regulation in type 2 diabetes. | Continue reading
People infected with a variant first identified in South Africa are more likely to die than those infected with other variants. | Continue reading
Despite geneticists being warned about spreadsheet problems, 30% of published papers contain mangled gene names in supplementary data. | Continue reading
Intriguing rocks turned out to be too crumbly for Perseverance to drill successfully. It’s moving on to try elsewhere. | Continue reading
Previously documented record values of the fusion triple product in the stellarator Wendelstein 7-X are shown to be evidence for reduced neoclassical energy transport in this optimized device. | Continue reading
Chemical analysis of an ice age woolly mammoth’s tusk reveals the huge distances it travelled during its lifetime more than 17,000 years ago. | Continue reading
Emerging data suggest that Delta could spread more readily than other coronavirus variants among people vaccinated against COVID-19. But key questions remain. | Continue reading
Influenza A viruses spread through contact, large and small respiratory droplets (aerosols), but the relative importance of these modes of transmission is unclear. Cowling et al. model data from community trials of face masks and hand hygiene and find that aerosol transmission ac … | Continue reading
Widely-used technique is associated with increased mortality in low- and middle-income countries. | Continue reading
Rare tetraquark is one of dozens of non-elementary particles discovered by the accelerator, and could help to test theories about strong nuclear force. | Continue reading
Daily recorded infections have more than halved since mid-July. Few researchers anticipated such a sharp decline, and they are now struggling to interpret it. | Continue reading
Scientists are starting to get insights into the lingering disorder that affects some people infected with SARS-CoV-2 — but many mysteries remain unsolved. | Continue reading
The influential economist behind Europe’s research-funding plan lays out her reasoning. | Continue reading
The first assessment from the Intergovernmental Panel for Climate Change in eight years will sound the alarm on soaring temperatures, rising seas and extreme weather. | Continue reading
A choice experiment shows that perceived benefits of vehicle ownership, including non-use values such as schedule flexibility and status in addition to the transport value, are on average larger than their private costs. | Continue reading
Analysis reveals that strange turns of phrase may indicate foul play in science. | Continue reading
The Atlantic Meridional Overturning Circulation (AMOC) is currently strong, but transition to its weak mode could see significant changes in the climate system. This work presents an observation-based early-warning system for such transitions and shows that the AMOC may be approa … | Continue reading
Concerns over waning immunity and SARS-CoV-2 variants have convinced some countries to deploy extra vaccine doses — but it’s not clear to scientists whether most people need them. | Continue reading
The Atlantic Meridional Overturning Circulation (AMOC) is currently strong, but transition to its weak mode could see significant changes in the climate system. This work presents an observation-based early-warning system for such transitions and shows that the AMOC may be approa … | Continue reading
A step closer to predicting and treating early menopause. | Continue reading
Principles from the field of fair division are used to develop selection algorithms for citizens’ assemblies that produce panels that are representative of the population while simultaneously selecting individuals with near-equal probabilities. | Continue reading
The linkage between temperature change and extinction rates in the fossil record is well-known qualitatively but little explored quantitatively. Here the authors investigate the relationship of marine animal extinctions with rate and magnitude of temperature change across the las … | Continue reading
Complex interactions synchronize droplet motion. | Continue reading
Survey results show that many white-tailed deer, a familiar sight on US lawns and golf courses, have antibodies to SARS-CoV-2. | Continue reading
What can microbiologists who study human bowels learn from those who study the bowels of Earth? | Continue reading
A book from the Oxford–AstraZeneca team, and a documentary, go behind the scenes in the race to vaccinate the world. | Continue reading
Shooting glass beads across the inside of a satellite could probe the limits of quantum wave behaviour. Here’s how. | Continue reading
The hippocampus geometrically represents both physical location and abstract variables on a neural manifold in mice performing a decision-making task in virtual reality. | Continue reading
