The James Webb Space Telescope (JWST) and Nancy Roman Space Telescope are revealing the universe's earliest chapters in detail. To help astronomers understand what they are seeing, researchers at the Center for Astrophysics | Harvard & Smithsonian have developed "Lumina," one of the largest and most detailed simulations ever created of the early universe. [...]
Teacher shortages are affecting school systems in countries across the world. Governments have responded with initiatives to attract graduates into teaching. While much attention has focused on increasing supply, far less attention has been paid to why experienced teachers decide to leave, despite the high costs of turnover in recruitment, training and lost continuity. [...]
Researchers in the Neag School of Education are bringing a whole child screening assessment to a company that provides schools with a connected set of solutions that turn every student signal into timely, equitable, coordinated and measurable tools to track and manage supports. [...]
Every shallow-water coral reef ecosystem in Australia faces an extremely high risk of collapse by 2075, driven largely by projected ocean warming, according to a global assessment. [...]
One of the fundamental challenges of quantum computing is obtaining information from a quantum bit, or qubit. Unlike a conventional bit, which can be read repeatedly without altering its content, direct measurement of a quantum system typically causes the state to collapse before it can be determined. In other words, reading the information modifies it. [...]
University of Tübingen researchers have shown that crows, when confronted with a visual choice, make a decision twice as fast as humans and monkeys. In the experiment, two carrion crows took just 235 milliseconds on average to identify the direction in which a dot pattern was moving and to indicate their choice—while maintaining a high degree of accuracy. [...]
Storms battered northern Europe on Sunday, cutting power to more than 150,000 homes, forcing the cancellation of hundreds of flights and silencing phone networks. [...]
Who knew a monarch butterfly could borrow a cellphone to check in with friendly people he met on his journey? That is essentially what happens now that new technology has reduced the weight of a radio-pulse tag to less than half a gram (0.02 ounces). [...]
The Milky Way is home to hundreds of billions of stars arranged in a glorious spiral pattern. But beyond the obvious spiral, our galaxy has other physical characteristics. It's divided into a galactic bulge, a galactic disk and a galactic halo. [...]
Whether a community is prioritized for public support can depend on how its needs are measured, according to new research from the University of New Hampshire. The study found significant differences in how government screening tools identify communities, particularly in rural areas where those differences could affect access to funding. [...]
A team at HZB has, for the first time, reported polar vortices in (BaTiO₃/SrTiO₃)₁₀ superlattices on silicon. These results expand the range of materials and substrates on which polar topological textures can occur and open up new options for incorporating complex ferroelectric states into silicon-based technologies. [...]
In Quebec and across Canada, people working in child welfare do remarkable work to protect children and youth from maltreatment and to support families facing complex challenges. [...]
An online lesson takes an extra second to load. The wait may seem trivial, but in a study examining large learning platforms, these brief pauses were linked to unfinished assignments, lower scores and less time spent on the site. [...]
Dairy farmers sometimes use additives in their cattle housing to reduce emissions from slurry. Emissions of substances such as ammonia occur when urine and feces mix on the floor of the housing. At the same time, dairy farmers want to increase the fertilizing value of the manure when it is applied to agricultural land. [...]
Southern Africa has one of the most detailed and elaborate bodies of rock art anywhere in the world, from herds of running antelope to dancing men and humanoid beings with wings, hooves and horns. All are painted with fine brushstrokes or fingers. One thing this art lacks is stencils. [...]
The most comprehensive record yet of carbon dioxide stored underground through geological carbon dioxide storage has been published today, revealing that 43.6 million metric tons were sequestered in 2024 alone—a new annual record—and that 421.7 million metric tons have now been stored in the past three decades. [...]
Inspired by the ability of sea cucumbers to change the stiffness of their bodies, University of Waterloo researchers have developed a gel that could one day help repair damaged tendons and other soft tissues without leaving permanent material behind. [...]
In 1987, biologists captured the last free-flying condor to transfer it to captivity, and the largest flying North American bird species was officially declared extinct in the wild. Today, after decades of coordinated efforts and millions of dollars spent on captive breeding and reintroduction efforts, more than 300 condors have been restored to their natural environment. [...]
Raw, grilled, roasted, stuffed—there are many ways to enjoy bell peppers, also called capsicums, sweet peppers or paprika. Bell peppers originated in Central and South America and belong to the nightshade family along with tomatoes and eggplants. [...]
Stainless steel is widely used for its corrosion resistance, but it is not invincible. In environments containing chloride ions, such as seawater, pitting corrosion can occur. These pits often start at tiny particles called inclusions embedded in the steel. [...]
Understanding instabilities and turbulence in plasmas is one of the key challenges across a wide range of plasma research fields, including nuclear fusion, astrophysics and laser-plasma physics. In plasmas, slight disturbances can grow due to instabilities, and energy is transferred between structures of various sizes due to turbulence. These phenomena give rise to structures ranging from very small to large, which significantly influence the overall motion and energy flow of the plasma. [...]
Many topics in astronomy and astrophysics are esoteric. There's not much of a relationship between something like the supermassive black hole at the center of the Milky Way and the life of a regular person going about their business. But the sun is different. Its presence in our lives is inescapable. Its behavior, especially its flaring, has an impact. [...]
The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction of the Standard Model of particle physics, its magnetic moment should be exactly equal and opposite to the electron's. [...]
Current HIV medicines are effective at suppressing the virus in the blood. However, HIV can remain "asleep" or dormant inside certain immune cells and in the brain. These hidden pockets of virus, called HIV reservoirs, are the main reason HIV cannot be cured with today's treatments. [...]
Metallic materials used in extremely cold environments must maintain high strength, ductility and fracture toughness to support applications in aerospace, clean energy, superconducting systems and deep-space exploration. However, traditional alloys often suffer performance degradation at ultralow temperatures because of the long-standing trade-off between strength, ductility and toughness. Although metals may become stronger at lower temperatures, they can also become more brittle and prone to fracture. [...]
What seabirds eat might seem like a good starting point for identifying species that tend to accumulate plastic in their digestive systems. Yet a recent global analysis suggests that mapping the evolutionary relatives of birds could offer better clues than their diets or feeding methods alone. [...]
In places like South Asia, Africa and parts of the Americas, monsoon rains supply water for drinking, crops and hydropower for billions of people. Understanding the patterns that monsoons tend to follow can help people plan for drought risks affecting agriculture, reservoirs and hydropower across distant regions. [...]
Relatively simple changes to the way traditional brick kilns operate in Bangladesh can reduce pollution, save fuel and improve the quality of bricks they produce. [...]
The fossilized skull of a new species of mysterious meat-eating dinosaur from the Isle of Wight has been rediscovered in the collections of the Natural History Museum after over 100 years in storage. [...]
Punching a virtual response box or swinging a virtual lightsaber can dramatically improve learning on certain tasks, according to new research from Florida Atlantic University's College of Engineering and Computer Science, which challenges long-standing assumptions about how people learn. [...]
