The James Webb Space Telescope team has fully deployed the spacecraft's 70-foot sunshield, a key milestone in preparing it for science operations.
Physicists have directly observed ultracold atoms forming 'quantum tornadoes' in a spinning fluid of ultracold atoms. The observations record a key crossover from classical to quantum behavior.
We can now tell the difference between a wide range of plastic types and thereby separate plastics according to their chemical composition. This is absolutely ground-breaking and it will increase the rate of recycling of plastics immensely. The technology has already been tested at pilot scale and it will be implemented at an industrial scale in spring 2022.
Their legs may get more attention, but a new study says a crab's eyes have much to offer, too—at least scientifically.
The frequency of thunderstorms in some fast-growing African coastal cities has doubled over the past 30 years, with much of this increase linked to the impact of deforestation on the local climate, a study has found.
For driving in the rain, it's preferable that the raindrops roll or bounce off the windshield instead of coating it or even freezing. A team of engineers in the McKelvey School of Engineering at Washington University in St. Louis has found that conduction of heat plays a larger role than previously thought in the dynamics of droplets on smooth surfaces that repel water.
Many companies today use experiments to gather the data that drives their strategies. That's how Facebook knows whether a newsfeed change increased user engagement, or how a bank knows whether its new promotional strategy increased deposits.
The cells of female mammals have a dosage problem, because they have twice as many X chromosomes as are needed in the body. Consequently, one of them is randomly selected and switched off already during early embryonic development. The Xist gene awakens and produces hundreds of RNA molecules, encasing one X chromosome and making it shrink into a small lump.
