Newly observed effect makes atoms transparent to certain frequencies of light
A newly discovered phenomenon dubbed "collectively induced transparency" (CIT) causes groups of atoms to abruptly stop reflecting light at specific frequencies......»»
Less is more: Why an economical iridium catalyst works so well
Iridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the iridium, is as efficient and stable over time as the best commer.....»»
TikTok ban still coming in January after new US law upheld
TikTok’s US ban is looming, and a new ruling by an appeals court has removed one of the last reasons for hope that the ban might not go into effect. more….....»»
Gurman: Apple-designed 5G modem coming to 2025 iPhones will be worse than Qualcomm’s
Apple’s long-in-the-works project to build its own cellular modem is about to see the light of day. As multiple reports have indicated in the past, select 2025 iPhone models will carry the Apple 5G modem—but thanks to a new report, now we know it.....»»
Speaking crystal: AI learns language of atom arrangements in solids
A new artificial intelligence model that can predict how atoms arrange themselves in crystal structures could lead to faster discovery of new materials for everything from solar panels to computer chips......»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
Citizen scientist data help uncover the mysteries of a blue low-latitude aurora
Colorful auroras appeared around Japan's Honshu and Hokkaido islands on May 11, 2024, sparked by an intense magnetic storm. Usually, auroras observed at low latitudes appear red due to the emission of oxygen atoms. But on this day, a salmon pink auro.....»»
Discovery of key protein complex shows evolution and adaptability of photosynthetic organisms
A team of researchers has revealed the structure of a modified and evolved version of Photosystem I (PS I), a key protein complex used by plants and cyanobacteria to convert sunlight into chemical energy. This discovery sheds light on the evolution a.....»»
Straining a material"s atomic arrangement may make for cleaner, smarter devices
What's the best way to precisely manipulate a material's properties to the desired state? It may be straining the material's very atoms, according to a team led by researchers at Penn State. The team discovered that "spray painting" atoms of potassiu.....»»
Plantain power: Reducing nitrate leaching in pasture systems
Nitrate leaching into water is a challenge globally and practical tools to reduce it are needed to aid in water quality improvement. Researchers from Teagasc investigated the effect of including ribwort plantain with grass-clover for reducing nitrate.....»»
The Amazon rainforest as a cloud machine: How thunderstorms and plant transpiration produce condensation nuclei
The rainforest in the Amazon basin transpires vast amounts of gaseous isoprene. Until now, it was assumed that this molecule is not transported far up into the atmosphere, as it rapidly declines when exposed to light conditions. The CAFE-Brazil measu.....»»
Getting a grip on quark mixing: Physicists introduce framework to determine amount of mixing between up and down quarks
The quarks that make up the nuclei of all atoms around us are known to "mix": the different types of quark occasionally change into one another. The amounts in which these processes happen are not very well known, though—and the theoretical values.....»»

Isotope analysis reveals mammoth as key food source for ancient Americans
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction o.....»»
Liquid water molecules are inherently asymmetric: New insight into the bonds between water molecules
Icebergs float on water because the underlying liquid water has a higher density than the iceberg. Liquid water itself has its highest density at 4°C—one of the so-called anomalies of water, i.e. properties of liquids that are rarely observed for.....»»
Webb finds new galaxies in Spiderweb protocluster field
Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics shed light on the growth of galaxies in these large cosmic cities, with the finding t.....»»
Supreme Court could narrow the scope of federal environmental reviews
In the 1993 movie "Jurassic Park," Dr. Ian Malcolm, a fictional math genius specializing in chaos theory, explains the "butterfly effect," which holds that tiny actions can lead to big outcomes. "A butterfly flaps its wings in Peking," Malcolm posits.....»»
