Environmental pollutants containing chlorine or bromine have been widely studied, but compounds containing both elements have remained largely unexplored. Researchers have now detected bromochloropyrene in industrial soils and harbor sediments, investigated its breakdown under
Researchers have created a molecular "cage" that keeps protein-degrading drug molecules inactive until they are exposed to low-energy red light. The technology, called RuPHOTACs, controls when and where these molecules become active, which could help scientists develop

Grades from compulsory school determine which pupils are accepted into popular upper secondary programs. A new thesis from Uppsala University shows that pupils at for-profit independent schools have, on average, higher grades than would statistically be expected given their
Quantum networks could one day connect quantum computers into more powerful systems and enable new forms of secure communication. But a fundamental obstacle stands in the way: Quantum information is extraordinarily fragile, and the entanglement between particles of light on
Nitrogen dioxide is a harmful gas that requires sensitive detection. Researchers used intense light pulses lasting 10 milliseconds to make molybdenum disulfide flakes and anchor isolated metal atoms in one step. Adding platinum improved the material's room-temperature response
Traditional speech-language therapy for people who stutter has largely operated under a medical model focused on eliminating dysfluency—breaks in the normal rhythm of speech. But for Rodney Gabel, a professor of speech-language pathology at Binghamton University, and Ladan
"How could our society have let this happen?"
A nanoscale particle with a unique structure, developed at MIT, holds potential as a customizable delivery vehicle for personalized cancer vaccines. The backbone of the vaccine is a modified, harmless bacteriophage called M13, which forms a nanofiber that can be coated with
Designed to study the powerful outbursts, the Swift Observatory quickly contributed to a wide range of discoveries. Now, it's about to meet a fiery fate.
For decades, astronomers treated the interstellar medium as a static backdrop to the goings-on of the universe. Now, a wave of 3D mapping is bringing the interstellar medium’s dynamic nature into focus. The post A New Map of ‘Empty’ Space Challenges a Tranquil Picture of the
A new modeling study, published in the journal Nature Climate Change, suggests that the East Antarctic Ice Sheet may be more resilient to extreme long-term warming than previously estimated. Increased snowfall, greater cloud cover and changes in atmospheric circulation could
A new study by academics at the University of Glasgow provides the most detailed analysis to date of Robert Burns' connections with Jamaica and relationship to the Atlantic slavery system.
NASA's Voyager team is celebrating two recent developments with the Voyager 1 spacecraft: In September, they successfully completed a months-long effort to stretch the spacecraft's diminishing power supply. Then, on Oct. 20, an unexpected loss of communication with the
African cuckoo finches (Anomalospiza imberbis) are very deceptive birds, or at least the mothers are. They sneak into the nests of other birds, such as prinias and cisticolas, to lay their eggs, then slip away and leave the hosts to raise the chicks.
A remarkably diverse fossil ecosystem in central Colombia that preserves an unusual overlap between survivors of older Jurassic groups and newer Cretaceous lineages has led researchers at McGill University and the Centro de Investigaciones Paleontológicas (CIP) to recognize a
Before a stick of deodorant reaches a consumer's bathroom counter, it moves through a complex supply chain. Raw materials and packaging components are sourced, assembled into a finished product and shipped through warehouses and distribution centers before finally reaching a

Astronomers using the James Webb Space Telescope (JWST) have found evidence that a distant, exceptionally blue galaxy may allow most of its ionizing radiation to escape into space. Known as EBG-1, the gravitationally lensed galaxy is seen at a redshift of 9.244, about 530
NASA's TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission has gathered its first clues to how space weather affects Earth's magnetic field. In a new paper published in the Journal of Geophysical Research: Space Physics, researchers break
The rice disease bacterial leaf blight (for short: BB) is causing significant yield losses in Asia and Africa. It is triggered by the bacterium Xanthomonas oryzae pv. oryzae (Xoo), which has many distinct regional strains on various continents.
Water is one of the most essential components of life, and many of its unique properties arise from interactions between its molecules. Hydrogen bonds influence water's physical properties, contribute to the formation of ice crystals and are crucial for normal biological
China's leading universities face two overlapping pressures: competing globally while remaining aligned with national strategic priorities. A study of 132 university president–party secretary pairs, conducted by a Hiroshima University researcher, found that 53% had different
Using a proof-of-concept test to analyze fragments of RNA in urine, researchers can detect cases of bladder cancer.
When we think of extraterrestrial intelligence that might be out there among the stars, we tend to think of creatures not too unlike us, though maybe with gray skin, probably bald and with big black eyes. We focus on the familiar, humanoids. But there are many intelligent
Walking has been shown to improve the overall health of a community and can predict the prevalence of chronic diseases, such as obesity, diabetes and cardiovascular disease, according to the World Health Organization. Because of this, city planners assess neighborhoods'
Once again, Australia's flying-foxes are in trouble.
For decades, physicists recognized only two types of magnetism that occur in materials without external influence: ferromagnetism and antiferromagnetism. In findings published in Science, a team led by the U.S. Department of Energy's SLAC National Accelerator Laboratory has
New research from the University of California, Davis, reveals why adding crushed shells to beach sand helps protect shell-making animals—such as clams, oysters and mussels—from the detrimental effects of ocean acidification.
Burrowing shrimp are a pest well known to shellfish growers. These pale-bodied creatures excavate mud as they dig into the ground, creating piles of sediment that suffocate oysters and clams growing on the surface. In estuaries on the West Coast, shrimp beds reach densities of
Ketamine and many other psychoactive substances can’t be detected by most standard drug screens, so it’s unclear how often they play a role in sexual assault. The post Ketamine’s Role in Alleged Cornell Rape Highlights Flood of Psychoactive Drugs on Campus appeared first on
Graphene, a material consisting of a sheet of carbon atoms arranged in a honeycomb pattern, has proved promising for various technological applications. Materials in which several layers of graphene are stacked together can exhibit different advantageous properties.
Generally, intra- and intersexual interactions have been considered qualitatively different processes. However, same-sex sexual behavior is widespread in the animal kingdom, challenging this assumption. Recently, a hypothesis was proposed that regards territorial contests in
An AI tool called REA can take apart software that isn’t meant to be opened in printers, smart TVs, cars, and more. Its pseudonymous creator wants everyone to get a peek
Prompting teachers to communicate high expectations and confidence in students' potential leads them to give more detailed feedback, according to a new study led by Yasemin Copur-Gencturk, Ph.D., a professor of education at USC Rossier and co-director of the USC STEM Center;
If you spend time watching online videos, you might feel like covering your ears. For some influencers, dropping f-bombs and other swear words is part of their brand, and their followers embrace it.

Researchers at the University of Tokyo have developed a high-speed microscopy technique that captures images so quickly they can be used to make "videos" of the dynamic processes that occur inside living cells.
Our cells are a hotbed of activity, with reactions churning away to keep us alive. But the cytoplasm, where many metabolic reactions take place, is not uniform. Instead, proteins and other molecules cluster together into membraneless compartments, creating distinct, crowded
