A 3D-printing technique has been developed that can produce millimetre- to centimetre-scale objects with micrometre-scale features. It relies on chemical reactions triggered by the intersection of two light beams.
Oscillations in neuronal activity in the medial temporal lobe of the human brain encode proximity to boundaries such as walls, both when navigating while walking and when watching another person do so.
Pain-sensing nerve cells can mobilize blood stem cells in mice, with a component of chilli peppers being one stimulus. The finding holds the promise of improving procedures for stem-cell transplantation.
A high-throughput technique has been developed to screen genes implicated in neurodevelopmental diseases in 3D cell cultures. It reveals a mechanism that might be involved in a rare disorder called microcephaly.
Most SARS-CoV-2 infections are undocumented. French health-care records and modelling were used to assess the rate of documentation of COVID-19 cases. The findings highlight the need for improved identification of infections.
Wetlands remove nitrate pollution from water effectively. An analysis shows that this effect is constrained in the United States by the distribution of wetlands, and could be increased by targeting wetland restoration to nitrate sources.
An atlas of European river barriers has been made, by curating and correcting existing records, and by surveying 2,700 kilometres of waterways. It reveals that rivers are fragmented by an amazing number of obstructions.
Atomic clocks known as optical clocks are more accurate and stable than current timekeepers. Two quantum-engineering approaches could improve the performance of optical clocks even further and extend their applications.
An analysis of more than 6 million YouTube videos finds that people around the world make similar facial expressions in similar social contexts. The study brings data science to the debate about the universality of emotion categories.
Precise maps of routine first-dose measles vaccinations show slowing progress around the world between 2010 and 2019, and large gaps in coverage in many places. Many countries are unlikely to achieve global 2020 coverage targets.
Populations of river fish are threatened by pressures on land and water resources. Networks of reserves managed by Indigenous people at community level offer a way to conserve fish diversity and enhance yields of nearby fisheries.
Structural data revealing how an anti-tuberculosis drug works could aid efforts to improve therapeutic options for the disease. The findings also uncover aspects of how the drug’s target, the ATP synthase enzyme, operates.
Computational models show that regionally varied prices for carbon emissions can greatly reduce the need for poor countries to receive financial assistance to tackle climate change, while still stabilizing global warming.
Dinosaur relatives called pterosaurs are the earliest known flying vertebrates. The branch of the evolutionary tree from which pterosaurs evolved has been unclear, but new fossil discoveries offer a solution to the mystery.
An analogue of the psychedelic drug ibogaine has been developed. The analogue mirrors ibogaine’s ability to treat addiction and depression in animal models, has fewer side effects and is much simpler to synthesize.
The nuclear forces that act on short-lived subatomic particles have been hard to study. This problem has now been solved by smashing high-energy protons together and measuring the momenta of the unstable particles produced.
A highly precise measurement of a physical constant known as the fine-structure constant provides a stringent test of the standard model of particle physics, and sets strong limits on the existence of speculative particles.
Neurons progressively deteriorate with age and lose resilience to injury. It emerges that treatment with three transcription factors can re-endow neurons in the mature eye with youthful characteristics and the capacity to regenerate.
Microscopy methods that reveal the spatial patterns of individual types of microbe are limited by the number of different species that can be monitored together. A new technique now provides progress on this front.
