Dark matter's existence is all but certain—astronomers believe it makes up about a quarter of the universe's total energy content—yet its true identity has eluded us for decades. Two of the leading candidates for dark matter are the hypothetical particles ultralight axions and dark photons, which in the range studied here would be some 19 to 21 orders of magnitude lighter than the electron. [...]
Young children often overestimate what they can do. That overconfidence may help them approach challenges without fear, but it can also get them into trouble. Children who overestimate their physical abilities, for example, may take risks that make accidental injuries more likely. [...]
With annual production of around 1 million metric tons (1.1 million tons), formic acid is one of the most important basic chemicals and is used, among other things, as an additive in the animal feed industry. It is also increasingly attracting attention as an H2 carrier. To date, its production has relied on fossil raw materials, which are to be replaced in the long term by sustainable raw materials. [...]
Black holes are fascinating regions in space where gravity is so strong that nothing, even light, can escape them. The largest known black holes, called supermassive black holes, contain millions to billions of times the mass of the sun and are typically located at the centers of galaxies. [...]
A 19th-century real estate agent created the world's first version of Rightmove more than 160 years before the birth of online property previews. [...]
Chiral phonons are groups of atoms that move in a circular direction when excited by an energy source, such as heat. As the phonons move through a material, they propagate that circular motion, or angular momentum, through the material. The angular momentum serves as the source of spin, and the chirality dictates the direction of the spin, enabling spin control in spintronics. [...]
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 the first Europe–wide assessment of changes in forest biomass. [...]
The wild boar (Sus scrofa) is widely distributed across Eurasia and has also colonized the Japanese archipelago, where two subspecies are recognized: the Japanese wild boar (JWB, Sus scrofa leucomystax) and the Ryukyu wild boar (RWB, Sus scrofa riukiuanus). Before this study, whole-genome sequence data were available for only a single wild boar from Japan whose geographic origin was unknown. As a result, the genetic relationship between JWB and RWB, as well as their evolutionary relationships with continental wild boar populations, remained unclear. [...]
Astronomers have speculated about the mysterious "little red dots" seen through the James Webb Space Telescope's images of the early universe: They could be galaxies, black holes, quasi-stars, starbursts ... or something else entirely. [...]
Using observations from multiple powerful telescopes, a team of astronomers studied a red quasar nicknamed "the Hatchling" at redshift 3.7. They may have identified one of the clearest examples yet of a quasar caught in transition between a heavily obscured and fully exposed phase. [...]
Zoos offer people the opportunity to experience animals and engage with the natural world. Alongside recreation, they also play important roles in species conservation and scientific research. Education is another core mission of modern zoos, with many programs designed to foster a stronger sense of connection to nature. But how effective are these initiatives? And which visitors benefit most from guided tours, workshops or multi-day educational programs? [...]
Neanderthals were generally more strongly built than most people living today. Their bones show signs of large muscles, and they had characteristic features such as prominent brow ridges and relatively short tooth roots. [...]
How and where did the first forms of life arise? These are the main questions driving research at the Institute of Molecular Evolution at Heinrich Heine University Düsseldorf (HHU). In a new publication in Science Advances, an international team led by Düsseldorf biologists uncovers pioneering insights into the network of chemical reactions that the very first cells used to make the building blocks of life and the energy sources they used to drive those reactions. [...]
Inspired by naturally occurring mats and balls of seaweed, researchers have created highly porous, superadhesive meshes capable of capturing both large and small microplastic particles—a longstanding challenge in the field. The mesh can clean microplastics from both saltwater and freshwater and is made from sustainable, widely available biopolymers. [...]
One-fourth of people who undergo an extraordinary experience report immediate discomfort, but more than half say the experience caused positive long-term effects, according to a study published Aug. 5, 2026, in the open-access journal PLOS ONE by Ronald Fischer of Instituto D'Or de Pesquisa e Ensino in São Paulo, Brazil, and colleagues. [...]
A research team led by Professor Hitoshi Yamamoto of Rissho University analyzed five years of longitudinal panel survey data collected between 2020 and 2024 and examined how vaccine-related conspiracy beliefs were associated with media skepticism during the COVID-19 pandemic. The study's results appear in Scientific Reports. [...]
Watersheds that are flatter, drier and warmer are generally more vulnerable to increases in flooding after trees are harvested. Those with greater variation in elevation spread runoff out over time, reducing flood peaks. [...]
Newborn German cockroaches use pheromones in cockroach feces to identify members of their own colony and form a kind of social bond, a discovery that could be used to improve pest control efforts. [...]
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 found that areas experiencing greater losses in tree canopy—land covered by trees' leafy crowns—also experienced higher mortality rates, particularly in the city's hottest neighborhoods. [...]
Babies start out life helpless and stay that way for a long time. They cannot walk, feed themselves or survive without an adult's continued care. Our dependency timeline has no clear parallel elsewhere in the animal kingdom. [...]
Disarticulated bones found scattered across a luxurious Roman villa on England's Isle of Wight may be evidence of a massacre carried out during a brutal political purge in the fourth century, a new study in Britannia suggests. [...]
You might think of rockets as powerful vehicles that blast astronaut crews and robotic missions into space. But what if they could be used to send cargo from one side of Earth to the other in a fraction of the time it would take a plane? The company SpaceX recently announced a project that aims to use its rockets to do just that. [...]
Severe storms, heat waves and wildfires can shut down the social life of a community, flooding out festivals, canceling community events and keeping people indoors. [...]
Researchers at the University of Bayreuth, together with colleagues from Freie Universität Berlin and the Leibniz Institute of Polymer Research Dresden, have developed a synthetic fiber system inspired by the cellular cytoskeleton that protects itself through controlled bundling. The findings open up new avenues for smart, switchable materials whose properties can be deliberately altered in response to a specific stimulus. The research is published in the journal Advanced Materials. [...]
Cells can switch off genes by tightly packaging DNA around proteins called histones. However, scientists at St. Jude Children's Research Hospital have discovered that under certain conditions, this packaging acts more like molasses than a solid, allowing a specially designed chemical adapter to shuttle gene-activating proteins through the packaging to the silenced gene inside. In addition, the researchers showed that this process reactivates the gene frataxin, which is abnormally silenced in the neurodegenerative disease Friedreich's ataxia. The study, published today in Nature Cell Biology, challenges a longstanding assumption that histone chemical modifications operate in a simple "on" or "off" binary manner. [...]
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 a growing interest in its medicinal and industrial potential for clothing, insulation and paper production. Many see it as a "green gold" opportunity for small-scale farmers. [...]
New research from Rutgers University–Newark psychologist Kent Harber reveals a strong connection between conspiracy theories, antisemitic attitudes and hostility toward Israel. [...]
As climate change causes water scarcity and temperatures to rise, crops around the world are feeling the heat. How can we prevent severe crop losses in these relentlessly sweltering conditions? An international research team led by Tohoku University has identified a new class of small molecules that enhances plant drought tolerance without any major negative impact on plant growth. [...]
New University of Georgia research suggests that social media could influence people's travel plans. The paper is published in the journal Current Issues in Tourism. [...]
In March 2026, the Einstein Probe detected a brief flash of soft X-rays emitted from a galaxy about 500 million light-years away. The flash, dubbed EP260321a, immediately triggered a worldwide observing campaign. Within an hour, ground-based telescopes began monitoring the source, revealing a rapidly brightening supernova, later designated SN 2026gzf. Two teams of scientists used several NSF NOIRLab facilities to observe the event and monitor its evolving light profile. [...]
