Two expeditions to the Thwaites Ice Shelf have revealed that it could splinter apart in less than a decade, hastening sea-level rise worldwide
Advanced materials can modify waves, creating optical illusions and useful technologies
For most of human evolution, multiple species with different ways of walking upright coexisted
Following Russia’s invasion on February 24, the lives of scientists in Ukraine, like those of everyone else in the country, were upended. Russia has targeted educational and research institutions, destroying 285 buildings and damaging 2,528, according to the Ministry of Education and Science of Ukraine.
Despite enormous efforts, physicists are still struggling to create a complete theory of turbulent flows. Perhaps they need a change of perspective.
Forces involved in everyday activities become so familiar that we overlook how complicated they can be.
People vaccinated not long after being infected with SARS-CoV-2 mount a weaker immune response than do those whose infections are well behind them.
Modelling suggests that tree cutting is a greater threat to the Milne-Edwards’s sifaka than are climate extremes.
Providing the clean fuel to manufacturing plants would be a cost-effective way to tackle the country’s climate goals.
For the first time, scientists simulate the worldwide spread of the staggering wave triggered by the Chicxulub impact.
After NASA’s DART asteroid-deflection experiment, a fully funded telescope for detecting space rocks is an equally pressing priority.
Although the marine ‘carbon sink’ is bigger than expected, it is still inadequate to keep global warming at bay.
The rise in electric-vehicle ownership could overload the electric grid unless charging becomes a daytime activity.
Scientists identify a neuronal pathway in rats that drives ‘social grooming’, a behaviour that helps to hold animal communities together.
As high-level winds shift, heat and heavy rain can persist.
Crystalline device could be used to visualize voltages with high resolution, speed and stability.
The trees that provide the raw material for chocolate have a higher yield when the groves are accessible to certain species.
A family tree of sea cows suggests that the dugong traversed an ocean to reach its present habitat.
Ground-based robots have potential for helping in the construction industry, but they are limited by their height. In this week’s issue, Mirko Kovac, Robert Stuart-Smith and their colleagues introduce highly manoeuvrable aerial robots that can perform additive 3D construction tasks. Inspired by natural builders such as wasps and bees, the researchers created BuilDrones (as shown on the cover) that can work in an autonomous team to perform 3D printing tasks using foam- or cement-based materials. They also created ScanDrones to assess the quality of the structures
being built. The team hopes that this approach of ‘aerial additive manufacturing’ could help to build structures in difficult to access areas.
Deaths and sufferings are not a failure of technology or knowledge, but a failure of will.
But carbon dioxide emissions resulting from the global reservoir-building spree in the 1960s and 1970s are falling.
A fossilized pile of small bones is probably a meal that an animal heaved up 150 million years ago.
Surrounding an ion of curium with radiation-resistant clusters of other ions allows scientists to study the scarce substance.
Some female white-necked jacobins nab good feeding spots by adopting the flashy plumage of their bigger, brasher male counterparts.
A high-sugar diet unbalances the microbiome, so the body makes fewer of the gut immune cells that help to prevent metabolic disorders.
