High-energy cosmic radiation damages cells and DNA, causing cancer, and secondary neutrons—generated especially from the planetary surfaces—can be up to 20 times more harmful than other radiations. Aluminum, the most widely used shielding material, has the drawback of
Agricultural producers and manufacturers often need information about crop attributes, from nutrient content to chemical composition, to make management decisions. In recent years, multispectral imaging has emerged as a useful tool for product analysis, but the required

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC Riverside-led study are published today in the Proceedings of the National Academy of
Researchers from the SNI network have discovered a novel way to fuse lipid vesicles at neutral pH. By harnessing a fragment of the diphtheria toxin, the team achieved vesicle membrane fusion without the need for pre-treatment or harsh conditions. Their work, recently published
Climate history recorded in a calcite deposit in a southern Nevada cave indicates that the hot, arid southwestern United States experienced significant shifts in temperature and rainfall over the last 580,000 years.
Researchers tracked thousands of Americans for decades, finding no links between ingesting recommended levels of fluoride and lower cognitive skills
When engineers struggled to make 3D printer nozzles narrow enough for their needs, they turned to nature and found the proboscis of a female mosquito had exactly the properties they needed
The depths of the Arctic Ocean have warmed more than scientists expected. New research has placed the blame on warmer water from Greenland
Earthquake faults deep in Earth can glue themselves back together following a seismic event, according to a new study led by researchers at the University of California, Davis. The work, published in Science Advances, adds a new factor to our understanding of the behavior of
Women are underrepresented among authors of retracted publications, particularly in cases involving multiple retractions, according to a new study published in PLOS One by Paul Sebo of the University of Geneva, Switzerland.
Although these findings from JWST are yet to be confirmed, they mark the closest astronomers have come to locating the universe’s most ancient stars
The nature of time has plagued thinkers for as long as we've tried to understand the world we live in. Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots.
We live in a time often characterized as a polycrisis. One of those crises is human-caused climate change, an issue currently being discussed by delegates at the COP30 climate talks in Belém, Brazil.
NASA's James Webb Space Telescope has delivered a first of its kind: a crisp mid-infrared image of a system of four serpentine spirals of dust, one expanding beyond the next in precisely the same pattern. (The fourth is almost transparent, at the edges of Webb's image.)
The Hațeg Basin in Transylvania is world-famous for its dinosaur remains, which have been unearthed from dozens of sites over the past century. Despite the high number of fossil localities, dinosaur finds are generally considered rare in the area. An exception is the newly
A group of researchers from the State University of Campinas (UNICAMP) in the state of São Paulo, Brazil, developed a product made from native bee honey and cocoa bean shells that can be consumed directly or used as an ingredient in food and cosmetics. The results were
As more states open the doors to legal marijuana, dispensaries are becoming a more common retail sighting. But what happens to the businesses next door when one opens for business?
A southern white rhino calf has been born at a zoo in eastern Spain, in a success for a European program aimed at preserving the threatened species.
In two newly published studies, researchers at the Department of Ethology, Eötvös Loránd University (Hungary) investigated how family dogs' ADHD-like traits relate to their learning and self-control. Dogs resemble humans in many ways—even traits similar to human
A study by Associate Professor Nevin Cohen and colleagues reveals that food waste in U.S. households varies significantly based on behavioral patterns and shopping habits, rather than simple demographics like age or income alone. The work is published in the journal Foods.
Imagine the catastrophic winds of a category 5 hurricane. Now, imagine even faster winds of more than 100 meters per second, encircling the planet and whipping clouds across the sky, with no end in sight. This scenario would be astonishing on Earth, but it's business as usual
Researchers from HSE University and the Space Research Institute of the Russian Academy of Sciences analyzed seven years of data from the ERG (Arase) satellite and, for the first time, provided a detailed description of a new type of radio emission from near-Earth space—the
In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in the direction of Earth's motion with that perpendicular to it. That arguably
Physics is often about recognizing patterns, sometimes repeated across vastly different scales. For instance, moons orbit planets in the same way planets orbit stars, which in turn orbit the center of a galaxy.
Water is essential for all chemistry and life, yet understanding how it interacts with dissolved ions—such as sodium and magnesium—has long been a major scientific challenge.
