Changing how people shower, report leaks and flush toilets could help close England's projected five billion liter daily water shortfall—but only if the water sector builds the evidence base to make it work, according to a new report led by the University of Surrey. The report is published to coincide with World Water Day on Sunday, March 22. [...]
K-12 teachers and students across the country are increasingly using AI in and out of classrooms, whether it is teachers turning to AI to refine lesson plans or students asking AI to help them research a particular topic. [...]
In a new, survey-based study of three kinds of "designer" crossbreed dogs, cockapoos, cavapoos and labradoodles, all three showed more undesirable behaviors than at least one of their purebred progenitor breeds, with cockapoos displaying the most unwanted habits. Gina Bryson of the Royal Veterinary College, U.K., and colleagues present these findings in the open-access journal PLOS One. [...]
Students who attend schools with smartphone bans report missing sleep to make up for "lost time" on their phones but benefit from more face-to-face socializing in the school day, as a new UK study reveals a mixed picture of how phones affect secondary school students' experiences. In the latest study from the SMART Schools project published in Social Sciences and Medicine, a team of academics from the University of Birmingham conducted in-depth research with seven schools to identify ways in which smartphone policies influence well-being among students. [...]
The trajectory of base editing has been remarkable, progressing from the laboratory to patient care, treating debilitating or terminal illnesses, in less than a decade. A type of gene editing that makes chemical changes to our DNA, base editing was developed by Alexis Komor, associate professor in the Department of Biochemistry and Molecular Biophysics at the University of California San Diego. [...]
Panic buying doesn't just respond to shortages—it creates them. And according to a University of the Sunshine Coast behavioral scientist, the lessons learned during COVID-19 remain critical for preventing future buying frenzies. [...]
New analyses of ancient ice from Antarctica and the air contained inside it are extending the history of Earth's climate records and expanding researchers' understanding of how the planet has changed over the last 3 million years. [...]
Cameras that photograph insects overnight and AI that identifies them are among a new generation of tools that could finally allow scientists to track whether the world's plan to save nature is working for its most overlooked creatures. A global team of scientists has found that 23 biodiversity targets agreed by world governments to protect and restore nature by 2030 are well-designed and could—if met—help reverse falling insect numbers. [...]
Cells in our bodies produce RNA based on genetic information stored in DNA, and RNA serves as a blueprint for making proteins. Researchers at KAIST have discovered a new phenomenon: Removing "circular RNA" that accumulates in cells as we age can slow down aging and extend lifespan. This study provides crucial clues for uncovering the principles of aging and developing treatment strategies for related diseases. [...]
For modern residents of the Levant, the "Red Sea Trough" usually brings a brief, dusty transition between seasons. But 127,000 years ago, this same weather pattern may have been the literal key to human history. A new study, led by Ph.D. student Efraim Bril, Prof. Adi Torfstein and Dr. Assaf Hochman from the Institute of Earth Sciences at the Hebrew University of Jerusalem and published in Climate of the Past, reveals that during the Last Interglacial (LIG) peak, the Levant wasn't just a dry bridge between continents, it was dynamic with more relatively wet conditions fueled by intense, localized rain. This shift in ancient weather likely provided the water sources necessary for early humans to successfully migrate "out of Africa." [...]
Antidepressants and other psychoactive drugs are designed to affect the human brain. But after they enter the water system in excrement or unused drugs flushed down the drain, traces of these compounds can enter the environment in biosolids—the nutrient-rich material left over after wastewater treatment that is used as fertilizer. New research suggests an unexpected mitigation strategy: using wood-rotting fungi that can break down these chemicals before they reach soil, crops, and people. [...]
As climate change reshapes Arctic food webs, ringed seals will swim into risky polar bear territory if the menu is varied enough. This is the central finding of a new study published in Ecology Letters. UBC researchers tracked 26 ringed seals and 39 polar bears in eastern Hudson Bay, using GPS and dive information to analyze how the animals found, and avoided becoming, food. [...]
Researchers from Ludwig-Maximilians-Universität München, the University of Hamburg, Freie Universität Berlin and the Fraunhofer Institute for Digital Media Technology IDMT show in a recent publication in the journal Nature Climate Change that television in Germany remains one of the most important media for engaging with the issue of climate change. Moreover, television can contribute to societal consensus-building. The study finds that climate-related television content primarily reaches news-oriented audiences, while disengaged and skeptical groups rarely encounter the topic due to their preferred TV formats. [...]
Researchers at the University of Missouri have discovered certain proteins may be the key to saving plants' lives when multiple stressors hit at the same time. This knowledge may one day lead to crops that are more resistant to harsh conditions brought on by multiple stressors during the same growing seasons. [...]
Glass appears to be a solid, but in theory it sometimes behaves more like an extremely slow liquid. Physicists in Utrecht now show that glass-like structures can also exist in equilibrium, which is something many theories say should be impossible. [...]
Research by Cardiff University has found that playing with Barbie dolls can help reach key milestones in developing empathy and social understanding during childhood. Doll play was found to be beneficial for both boys and girls, and is particularly valuable for those experiencing problems with their peers. The work appears in PLOS One. [...]
Researchers at the University of St Andrews have unveiled two breakthrough techniques for chemically recycling and upcycling nitrile‑rubber products, such as disposable gloves, seals, and industrial parts, into new materials that are also capable of capturing carbon dioxide. [...]
A team led by La Trobe University has drawn inspiration from nature to develop a breakthrough sensor that can rapidly track tiny molecular changes in blood, paving the way to real-time, personalized medicine. The discovery overcomes one of the biggest barriers in blood testing: that blood quickly clogs most sensors, making accurate instant readings almost impossible over long periods of time. The work is published in the journal ACS Sensors. [...]
Entomologists have discovered a new species of mining bee that has an unusually tight relationship with cenizo, the official state shrub of Texas. Silas Bossert, assistant professor in Washington State University's Department of Entomology, worked with colleagues in Texas and Kansas to identify and describe the new mining bee, Andrena cenizophila. [...]
The conversion of carbon dioxide (CO₂) into carbon monoxide (CO), an industrial feedstock, has attracted significant attention as a key step for producing synthetic fuels and chemical products. However, because CO₂ is a chemically stable molecule, the reaction typically requires high temperatures of 500–600 °C or higher, and catalyst performance often degrades during operation. [...]
Affordable, green energy production has long been promoted as a means to accelerate the decarbonization of sectors such as heavy industry, long-duration energy storage, and transportation, which are difficult to electrify. Such decarbonization would reduce greenhouse gas emissions while strengthening energy security and economic resilience. [...]
The pinewood nematode (Bursaphelenchus xylophilus) is the most devastating parasite of pine forests across Eurasia. To combat the pinewood nematode, European regulation requires that Member States clear-cut all susceptible tree species within a 500 meter radius of infested trees. However, this measure has not made it possible to eradicate the disease in Portugal, and a previous modeling study showed it was not effective in vast, pine-only forests. [...]
Researchers at UCLA's Institute of the Environment and Sustainability have developed the most high-resolution statewide maps of California's kelp forests to date, giving researchers, conservationists and community members unprecedented access to information essential to maintaining coastal ecosystems and the communities they support. [...]
A severe drought, powerful Santa Ana winds and a not-fully-extinguished brushfire combined to create the most destructive wildfire in the history of Los Angeles in early 2025. The Palisades Fire, which fully ignited on Jan. 7, destroyed Los Angeles' Pacific Palisades neighborhood, killing 12 people and burning 6,800 homes and buildings. [...]
Hydrological models represent water movement in natural systems, and they are important for water resource planning and management. But the models depend on reliable input data for weather factors, and precipitation can be very difficult to measure and represent accurately. A recent study in Environmental Modelling & Software by an international research team describes a novel method to better represent precipitation uncertainty in hydrological models, thereby improving their performance. [...]
Utilization of biomass as a chemical resource is a promising strategy for establishing a circular economy. Cellulose, a polymer composed of glucose units, is the most abundant form of biomass, and glucose is a versatile feedstock for chemicals. However, cellulose is a highly recalcitrant material due to its extensive hydrogen-bond (H-bond) network. [...]
A new study, led by Woods Hole Oceanographic Institution (WHOI) and Columbia University, identifies a diverse set of molecules released by marine phytoplankton that fuel microbial life and help drive Earth's carbon cycle. While scientists know that carbon is moved through an invisible network of phytoplankton and other microbes in the surface ocean, the specific compounds have long been a mystery. These compounds are small, chemically difficult to detect in salty seawater, and are rapidly consumed by other organisms almost as soon as they are produced. [...]
Efforts to prevent pathogenic contaminations such as salmonella in dry food processing facilities will take a step forward through new research from the University of Massachusetts Amherst describing a novel chemical mixture for sanitation in low-moisture environments. [...]
An international team led by University of Alicante (UA) scientists has found that increasing the share of organic farming may improve crop yields and help maintain soil health and biodiversity. Published in the journal Nature Sustainability, the study concludes that landscapes with at least 50% organic farming optimize crop yields, soil biodiversity and key ecosystem functions such as carbon storage, nutrient cycling and water regulation. [...]
What will the computers of tomorrow look like? Chances are good that spintronics will play a decisive role in the next generation of computers. In spintronics, the intrinsic angular momentum of an electron (the spin) is used to store, process and transmit data. This technology is already in use today, for example in hard drives. However, the scope of what is possible extends much further: More recent approaches aim at using not just individual spins, but entire spin waves made up of partly hundreds of trillions of spins. Such collective spin excitations are known as magnons. They could enable extremely energy-efficient data transmission—even in the terahertz range. [...]
