Coral reefs are often described as biodiversity hotspots, but new research shows they also act as powerful regulators of the microscopic life in the surrounding ocean. [...]
Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using conventional technologies used by physicists to study matter particles. [...]
Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the Milky Way galaxy, such as its gravitational potential and the distribution of matter. Now astronomers from China have made a large-volume search for hypervelocity stars by utilizing a special class of stars known for their distinct, regular, predictable pulsation behavior that makes them useful as distance indicators. [...]
Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found evidence against the existence of a "sterile" type of neutrino hypothesized to be responsible for previous experiments' anomalous results, as detailed in a paper published in Nature. [...]
Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by Niels Bohr and his school of physicists. Bohr claimed there are properties of particles that cannot simultaneously be measured. The new result backs up the Copenhagen school yet again, with the potential to shed light on other, less settled questions in quantum mechanics. [...]
Ammonia (NH3) is a colorless chemical compound comprised of nitrogen and hydrogen that is widely used in agriculture and in industrial settings. Among other things, it is used to produce fertilizers, as well as cleaning products and explosives. [...]
Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the past decades, researchers have introduced several new quantum information frameworks and theories that are informing the development of quantum computers and other devices that operate leveraging quantum mechanical effects. [...]
Using the Einstein Probe (EP), astronomers have detected a new X-ray transient event, which turned out to be an X-ray flare from the star PM J23221-0301 located about 150 light years away. The finding was reported in a research paper published December 18 on the arXiv preprint server. [...]
Winds exceeding 110 mph that tore across the top of Mount Hamilton early Christmas morning blasted a massive steel protective door off the iconic white dome at Lick Observatory. [...]
Winter is hard, and for wildlife in Colorado, it's even harder. To survive, many species have developed adaptations over hundreds of thousands of years that allow them to weather the storms, including hibernation, thicker coats, food storage and migration. [...]
High in the mountains west of Fort Collins, teams of scientists and engineers are pretending to be beavers. [...]
Central Asia, the Sahel region and northern Europe experienced their hottest year on record in 2025, according to AFP analysis based on data from the European Copernicus program. [...]
Sport is one of the most climate-sensitive aspects of Australian life, yet still sits largely outside the national conversation on climate exposure. [...]
The intermittent nature of solar energy poses challenges to grid stability, making accurate ultra-short-term solar irradiance forecasting crucial for balancing supply and demand. However, traditional numerical weather prediction models often struggle with cloud initialization, leading to forecast inaccuracies. [...]
Palladium is widely used in various industries and everyday products, including smartphones, semiconductor manufacturing processes, and hydrogen fuel cells. It is an essential metal that acts as an excellent catalyst even in minute quantities, reducing pollutants and enhancing energy efficiency. However, palladium production is concentrated in a few countries, leading to an unstable supply. South Korea generates significant amounts of spent catalysts and electronic waste annually, and a lack of eco-friendly and efficient recovery technologies means much is discarded. [...]
Among his other ongoing projects, US President Donald Trump has spent much of his second term on a renovation. The Oval Office has been converted into a miniature palace festooned with gold bling, the rose garden has been paved over, a triumphal arch is planned and the new ballroom will be larger than the White House. [...]
It's a Wednesday evening in a town hall in Penryn in Cornwall, and my friend Pete and I are volunteering at our local repair cafe. We set up tables, get our tools ready, put up a sign outside and wait for people to arrive. [...]
In this Oct. 20, 2025, photo, tiny ball bearings surround a larger central bearing during the Fluid Particles experiment, conducted inside the Microgravity Science Glovebox (MSG) aboard the International Space Station's Destiny laboratory module. [...]
Why does cancer sometimes recur even after successful treatment, or why do some bacteria survive despite the use of powerful antibiotics? One of the key culprits identified is "biological noise"—random fluctuations occurring inside cells. [...]
Celebrate the New Year with the "Champagne Cluster," a galaxy cluster seen in this new image from NASA's Chandra X-ray Observatory and optical telescopes. [...]
Immunotherapy has emerged in recent years as a new cancer treatment that is gentler than traditional chemotherapy and causes milder side effects in patients. However, conventional dendritic cell (DC) immunotherapy shows inconsistent clinical outcomes, and the cell culture process remains complex and costly. [...]
Social media posts about unemployment can predict official jobless claims up to two weeks before government data is released, according to a study. Unemployment can be tough, and people often post about it online. [...]
Since the interstellar object (ISO) 3I/ATLAS was first discovered on July 1, 2025, it has garnered much attention, including speculation, hopes and fears that it may somehow contain evidence of technologically advanced civilizations outside of our solar system. [...]
Preliminary analysis rules out a lab leak as the cause of an African swine fever outbreak that has rocked Spain's lucrative pork industry, but further tests are needed, authorities said Tuesday. [...]
The flames die down. The sirens fade. Firefighters peel off their gear, thinking the danger has passed. But in the quiet aftermath, another enemy lingers, an invisible film of "forever chemicals" clinging to jackets, pants and masks. [...]
A French ban on the production and sale of cosmetics and most clothing containing polluting and health-threatening "forever chemicals" goes into force on Thursday. [...]
The year's first supermoon and meteor shower will sync up in January skies, but the light from one may dim the other. [...]
On Jan. 7, 2025, people across the Los Angeles area watched in horror as powerful winds began spreading wildfires through neighborhood after neighborhood. Over three weeks, the fires destroyed more than 16,000 homes and businesses. At least 31 people died, and studies suggest the smoke and stress likely contributed to hundreds more deaths. [...]
Mid-infrared observations from NASA's James Webb Space Telescope, shown in white, gray, and red, are combined here with X-ray data from NASA's Chandra X-ray Observatory, highlighted in blue. Together, these different wavelengths reveal a detailed and layered view of a pair of colliding spiral galaxies, captured in an image released on Dec. 1, 2025. [...]
In recent weeks, powerful atmospheric river storms have swept across Washington, Oregon and California, unloading enormous amounts of rain. As rivers surged, they overtopped or breached multiple levees—those long, often unnoticed barriers holding floodwaters back from homes and towns. [...]
