Nanoclusters self-organize into centimeter-scale hierarchical assemblies
Nature may abhor a vacuum, but it sure loves structure. Complex, self-organized assemblies are found throughout the natural world, from double-helix DNA molecules to the photonic crystals that make butterfly wings so colorful and iridescent......»»
NASA astronauts test SpaceX elevator concept for Artemis lunar lander
NASA astronauts Nicole Mann and Doug "Wheels" Wheelock participated in a recent test of a sub-scale mockup elevator for SpaceX's Starship human landing system that will be used for NASA's Artemis III and IV missions to the moon. The Starship human la.....»»
The two (country) sides of forests: How do public policies influence conservation?
How do national policies impact deforestation? Researchers from the University of Bonn have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant—and visible—infl.....»»
Galaxy-scale winds spotted in the distant Universe
These winds can drive gas out of galaxies, shaping their future evolution. Enlarge / X-ray emissions (purple) superimposed on a visible light image of a galaxy shows the galaxy winds being launched. (credit: X-ray: NASA/CXC/The O.....»»
Scientists uncover link between ocean weather and global climate, using mechanical rather than statistical analysis
An international team of scientists has found the first direct evidence linking seemingly random weather systems in the ocean with climate on a global scale. Led by Hussein Aluie, an associate professor in the University of Rochester's Department of.....»»
The best smart scales for measuring body fat, Apple Health, and more

Electrocatalytic CO₂ conversion advancing toward large-scale deployment
Global CO2 emissions continue to grow, reaching 36.1 Gt in 2022, stimulating the implementation of carbon taxes and impacting energy use. The electrocatalytic CO2 reduction reaction (CO2RR) to produce high value-added chemicals and liquid fuels contr.....»»
Giant bacterium powers itself with unique processes
Not all bacteria are created equal. Most are single-celled and tiny, a few ten-thousandths of a centimeter long. But bacteria of the Epulopiscium family are large enough to be seen with the naked eye and 1 million times the volume of their better-kno.....»»
Paying people to replant tropical forests and letting them harvest the timber can pay off
Tropical forest landscapes are home to millions of Indigenous peoples and small-scale farmers. Just about every square meter of land is spoken for, even if claims are not formally recognized by governments......»»
Seafloor geodetic positioning model achieves centimeter-level precision
In a study published on 4 December 2023, in the journal Satellite Navigation, researchers from Chinese Academy of Surveying and Mapping have developed a self-structured Empirical SSP (SESSP) approach to overcome previous limitations. This novel metho.....»»
Computational scientists generate molecular datasets at extreme scale
A team of computational scientists at the Department of Energy's Oak Ridge National Laboratory has generated and released datasets of unprecedented scale that provide the ultraviolet visible spectral properties of over 10 million organic molecules. U.....»»
First ground-based survey of damage to Ukrainian cultural sites reveals severity, need for urgency
The war in Ukraine is not just a war against a people, but a war on culture. And after nearly two years of fighting, it is destroying Ukraine's cultural heritage on a scale not seen since World War II, according to new research by University of Notre.....»»
Attackers abuse OAuth apps to initiate large-scale cryptomining and spam campaigns
Attackers are compromising high-privilege Microsoft accounts and abusing OAuth applications to launch a variety of financially-motivated attacks. Abusing OAuth applications OAuth is an open standard authentication protocol that uses tokens to grant a.....»»
Natural gas is actually migrating under permafrost, and could see methane emissions skyrocket if it escapes
Beneath Svalbard's permafrost, millions of cubic meters of methane are trapped—and scientists have now learned that it can migrate beneath the cold seal of the permafrost and escape. A large-scale escape could create a cycle of warming that would s.....»»
New report outlines opportunities to remove CO2 at the gigaton scale
Scientists from more than a dozen institutions have completed a first-of-its-kind high-resolution assessment of carbon dioxide removal potential in the United States, charting a path to achieve a net-zero greenhouse gas economy by 2050......»»
Planting less water-intensive crops in the western United States would help alleviate water scarcity, study finds
Across the world, irrigation dominates freshwater consumption, accounting for 88% of all the freshwater consumed on a global scale. In the western United States, this is no different, as irrigated farming is the leading driver of water depletion in t.....»»
New ways to make ordered wafer-scale chiral carbon nanotube architectures
Chiral materials interact with light in very precise ways that are useful for building better displays, sensors and more powerful devices. However, engineering properties such as chirality reliably at scale is still a significant challenge in nanotec.....»»
The quest to turn basalt dust into a viable climate solution
Sprinkling rock dust on farmland to soak up atmospheric carbon will be tested at large scale. Enlarge (credit: Lithos Carbon) Mary Yap has spent the last year and a half trying to get farmers to fall in love with basalt......»»
