A material made of overlapping layers of graphene (atom-thick sheets of carbon) changes colour according to the level of stress applied. This could be used in structures to provide early warning of damage.A team led by Shanglin Gao of the Leibniz Institute of Polymer
Viruses more often evolve by jumping from one host species to another than by remaining within a particular species.Edward Holmes and his colleagues at the University of Sydney in Australia compared the evolutionary histories of 19 virus families with those of their animal or
Mining the deep seabed is fraught with challenges. Untapped mineral potential under the shallow, more accessible continental shelf could add a new dimension to offshore mining and help meet future mineral demand.
Hints from seismic tomography and geochemistry indicate that Earth's mantle is heterogeneous at large scale. Numerical simulations of mantle convection show that, if it started enriched in silicates, the lower mantle may remain unmixed today.
Dissolved iron is mysteriously pervasive in deep ocean hydrothermal plumes. An analysis of gas, metals and particles from a 4,000 km plume transect suggests that dissolved iron is maintained by rapid and reversible exchanges with sinking particles.
A global cooling trend culminated in the glaciation of Antarctica during the Eocene–Oligocene transition. Simulations suggest that ocean circulation changes and enhanced drawdown of atmospheric carbon dioxide can explain this climate shift.
Three-dimensional (3D) stem cell differentiation cultures recently emerged as a novel model system for investigating human embryonic development and disease progression in vitro, complementing existing animal and two-dimensional (2D) cell culture models. Organoids, the 3D self-organizing structures derived from pluripotent or somatic stem cells, can recapitu […]
The accumulation of damaged and aggregated proteins is a hallmark of aging and increased proteotoxic stress. To limit the toxicity of damaged and aggregated proteins and to ensure that the damage is not inherited by succeeding cell generations, a system of spatial quality control operates to sequester damaged/aggregated proteins into inclusions at specific p […]
We present a special issue highlighting considerations and recent developments in noninvasive techniques that improve our understanding of neural measurements in humans, bridging the gap between human and animal research in neuroscience.
The validity of conclusions drawn from functional MRI research has been questioned for some time now. Nature Neuroscience and Nature Communications are committed to working with neuroimaging researchers to improve the robustness and reproducibility of their work.
Responding to widespread concerns about reproducibility, the Organization for Human Brain Mapping created a working group to identify best practices in data analysis, results reporting and data sharing to promote open and reproducible research in neuroimaging. We describe the challenges of open research and the barriers the field faces.
A revolution is underway in cognitive neuroscience, where tools and techniques from computer science and the tech industry are helping to extract more meaningful cognitive signals from noisy and increasingly large fMRI datasets. In this paper, the authors review the cutting edge of such computational analyses and discuss future opportunities and challenges.
The snow leopard is one of the most elusive creatures on the planet, living in one of the most hostile environments on Earth. Here Wildscreen Exchange and Arkive contributor Craig Jones shares with us his experience in tracking and photographing this mysterious and endangered big cat in the Himalayan mountains. This incredible expedition took us to […]
Today the dingo has been crowned the World’s Favourite Unloved Species, after two weeks of voting and some fierce competition. Here Bret Charman discusses his experiences with photographing this misunderstood yet beautiful species. The world’s wild dog species, for the most part, are on a downward spiral – none more so than the iconic dingo […]
#LoveSpecies nominee: helmeted hornbill Nominated by: World Land Trust Why do you love it? The fierce appearance of the world’s largest hornbill, with a battering ram of solid keratin fixed to their face, suits its medieval mating rituals. The males clash mid-air in head-to-head combat (an impressive display called aerial jousting) to win access to fruiting […]
#LoveSpecies nominee: Galapagos giant tortoise Nominated by: Ecology Project International Why do you love it? The Galapagos giant tortoise has had such an impressive impact on history, science, and its ecosystem that it’s sure to win over hearts. Endemic to the Galapagos Islands off the coast of Ecuador, this tortoise is one of only two distinct […]
