The Arctic is warming at an accelerating pace. As permafrost thaws across vast areas and wildfires become more frequent, large amounts of methane (CH4) are being released. Together, these changes are reshaping the region's ...
Today's quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase energy demands. In new work, researchers have demonstrated that quantum entanglement between photons ...
High-energy particles in Earth's radiation belt can appear to spread out randomly, even when they are moving in a "predictable" way. This is because spacecraft observations naturally blur the fine-scale structure of the particle ...
Mangroves are perplexing plants. They breathe through their roots, appear to stand on stilts and grow best in hot, salty seawater drawn in and out by the tide.
Methane is an especially potent greenhouse gas, causing much more warming than carbon dioxide on a unit-for-unit basis—and a new, uniquely long-term study of emissions at a New Jersey landfill suggests that estimates of methane ...
Lasers have become indispensable in everyday life and research, with applications ranging from data transmission and metrology to manufacturing. Masers, by contrast, have so far found hardly any practical applications.
Using satellite data, researchers at TUM have identified an unprecedented loss of aboveground biomass in Europe's forests since 2018. Unlike previous studies that focused solely on changes in tree cover, this study provides ...
As trees disappear from urban neighborhoods, lives may be lost with them. In a new study, Northwestern University scientists tracked death rates and fluctuations in tree canopy cover across an 11-year period in Chicago. They ...
In South Africa, it's been legal for several years for people to grow hemp (a type of Cannabis sativa with very low levels of the psychoactive compound THC) for personal use following changes to the law. There's also been ...
Fires in the Arctic are not solely a regional issue, as shown by the hazy skies in Switzerland last summer despite otherwise sunny weather. Smoke from major fires in northern Canada crossed the Atlantic and reached Europe. ...
