This Feb. 4, 2026, image from NASA's Solar Dynamics Observatory (SDO) captures a strong solar flare erupting from the star. Solar flares are powerful bursts of energy that can, along with other types of solar eruptions, impact radio communications, electric power grids,
Researchers used AI-driven virtual players to test more than 100 rule sets, matching gameplay to wear patterns on a Roman limestone board.
Harbor porpoises "buzz" less when boats and ships are nearby—suggesting a drop in feeding and socializing, new research shows. The paper, published in the journal Marine Mammal Science, is titled "Seasonal and diurnal patterns of harbor porpoise (Phocoena phocoena) behavior and
Polymer micelles are tiny, self-assembled particles that are revolutionizing the landscape of drug delivery and nanomedicine. They form when polymer chains containing both hydrophilic and hydrophobic segments organize into nanoscale spheres in liquid solutions; these structures
They say that love is a two-way street, but that may only hold true to a point. It turns out that couples who obsess over equal give-and-take may be sabotaging their relationship, suggests a study involving University of Toronto Mississauga researchers. The findings are
In her 1962 book, "Silent Spring," American biologist Rachel Carson revealed that DDT, a widely used pesticide at the time, was responsible for the mass death of birds, including the iconic bald eagle. One reason was that the pesticide made eggshells thinner, causing mothers to

In terms of area, forest is the most important means of avalanche protection. It is also the most cost-effective and is naturally renewable. This insight hit home after the winter of 1951, when over 1,000 avalanches caused immense damage. The SLF began researching how
Under the leadership of the University of Bonn, a research team led by Prof. Dr. Pavel Kroupa from the Helmholtz Institute for Radiation and Nuclear Physics has discovered that galaxy clusters are about twice as heavy as previously assumed. The additional mass comes mainly from
Despite a barren start to Colorado's ski season, Winter Park Resort opened on Halloween and served up holiday powder. The ski area's secret is a contraption a few miles upwind of the chairlifts that looks like a meat smoker strapped to the top of a ladder. When weather
Can we use nothing more than sunlight and inexpensive materials to produce clean hydrogen fuel while also removing toxic pollutants from water? That question shaped our recent work with γ-In2S3, a semiconductor that has intrigued researchers for years but still holds untapped
As carbon emissions continue to be pumped into the atmosphere at record levels, it will be critical to recapture and sequester as much of these warming gases as possible. While technological approaches face many barriers before they can be scaled up, efforts to capture carbon
Cornell researchers have discovered a new way cells regulate how they respond to stress, identifying an interaction between two proteins that helps keep a critical cellular recycling system in balance. The findings show that a protein called SHKBP1 regulates another protein,
Conventional air conditioners and refrigerators rely on vapor-compression cycles and chemical refrigerants that contribute significantly to global warming. Magnetic refrigeration offers a cleaner alternative using the magnetocaloric effect (MCE), a phenomenon where certain

Starting just outside Charlotte, North Carolina, a vast underground deposit of lithium stretches south for 25 miles. A key component of rechargeable batteries and energy grid storage systems, the soft, silvery metal is a global commodity, making this subterranean cache a
As glaciers around the world melt at unprecedented rates, tourism in these icy landscapes is booming, adding pressure to vulnerable regions and disrupting delicate ecosystems. A collective effort, led by UNIL and published in Nature Climate Change, points to ways of balancing
In nanoscale particle research, precise control and separation have long been a bottleneck in biotechnology. Researchers at the University of Oulu have now developed a new method that improves particle separation and purification. The promising technique could be applied, for

New research is proving persistent gender gaps in science, technology, engineering, and mathematics (STEM) careers can't be explained by academic ability alone. A recent Baycrest study suggests that success in STEM careers is shaped by different cognitive strengths and that
As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful alternative—quantum cryptography—offers security based on the laws of physics instead of computational difficulty. But to turn quantum communication into
If humans want to live in space, whether on spacecraft or the surface of Mars, one of the first problems to solve is that of water for drinking, hygiene, and life-sustaining plants. Even bringing water to the International Space Station (ISS) in low Earth orbit costs on the
The sun is the basis for photosynthesis, but not all plants thrive in strong sunlight. Strong sunlight constrains plant diversity and plant biomass in the world's grasslands, a new study shows. Temperature, precipitation, and atmospheric nitrogen deposition have less impact on
From fundamental biological units as tiny as genes to complex societies, ecological systems rely on cooperation. All manner of organisms can benefit from working together to survive in a dog-eat-dog world. "Mutualism is a common example of interspecies cooperation," says Utah
Using the Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical simulation (DNS) of turbulence in three dimensions, attaining a record resolution of 35
The nuclear envelope (NE) is a dynamic and selective barrier that organizes genome function and nucleocytoplasmic communication, and its structural deterioration is a hallmark of aging associated with diverse human diseases. Now, researchers from the Institute of Genetics and
Before leaving on a fossil-hunting trip for a summer 2021 field paleontology class, a Montana State University junior made an apparently fate-tempting plea. "I kept joking through that whole class, 'Oh, please, just anything but a turtle,'" said Jack Prall, now a doctoral
The human kidney filters about a cup of blood every minute, removing waste, excess fluid, and toxins from it, while also regulating blood pressure, balancing important electrolytes, activating Vitamin D, and helping the body produce red blood cells. This broad range of
A new genetic study examines an unusually large hybridization event that followed the Fukushima nuclear accident, when escaped domestic pigs bred with wild boar. The research shows that domestic pig maternal lineages sped up generational turnover, rapidly diluting pig genes.
About a year ago, researchers at the University of Michigan found that the extratropical cyclones that are the biggest drivers of winter weather in the Great Lakes region are warming and trending northward. That means, outside of the northern reaches of the region, residents
Scientists in the laboratory of Rendong Yang, Ph.D., associate professor of Urology, have developed a new large language model that can interpret transcriptomic data in cancer cell lines more accurately than conventional approaches, as detailed in a recent study published in

How did the complexity of many organisms living today evolve from the simpler body plans of their ancestors? This is a central question in biology. Take our hands, for example: Every time we type a message on our mobile phone, we are using an evolutionary "masterpiece" that
Around the Balkan Peninsula, the African plate is sinking beneath the European plate. A piece of deeply submerged African crust resurfaced 40 million years ago far away from the sinking zone. How this phenomenon of so-called vertical extrusion can be explained and whether the
Most materials have an inherent capacity to handle heat. Plastic, for instance, is typically a poor thermal conductor, whereas materials like marble move heat more efficiently. If you were to place one hand on a marble countertop and the other on a plastic cutting board, the
New forms of fentanyl are created every day. For law enforcement, that poses a challenge: How do you identify a chemical you've never seen before? Researchers at Lawrence Livermore National Laboratory (LLNL) aim to answer that question with a machine learning model that can
Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA's OSIRIS-REx mission. How those amino acids—the molecules that create proteins and peptides in
