Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The extreme environment inside these devices, however, can damage materials that surround the superheated, electrically charged plasma where the nuclear fusion reaction takes place. https://phys.org/news/2026-08-tungsten-fusion-reactors.html Condensed Matter Sat, 15 Aug 2026 08:40:01 EDT news705839207 Long before dark sunspots appear on the sun's surface, a new active region—where powerful solar eruptions can originate—begins showing subtle signs of its formation. Now, researchers say a new artificial intelligence model can detect those early signals and forecast the emergence of solar active regions nearly nine hours in advance on average. https://phys.org/news/2026-08-ai-hidden-solar-eruptions-hours.html Planetary Sciences Fri, 14 Aug 2026 09:00:01 EDT news705840421 Future fusion power plants aim to recreate the heart of a star here on Earth to power our future energy needs. While the core fusion plasma will burn at hundreds of millions of degrees, the surrounding structural components must handle sudden, punishing heat loads that rival the extreme temperatures faced by spacecraft upon reentry into Earth's atmosphere. Copper and its alloys are primary candidates for handling these intense heat fluctuations, making it vital to understand exactly how the metal behaves when pushed to its melting point. https://phys.org/news/2026-08-copper-behavior-insights-future-fusion.html Condensed Matter Thu, 13 Aug 2026 15:20:03 EDT news705842131 From smartphones to data centers, modern electronics rely on billions of tiny switches that consume electricity every time they turn on or off. As global demand for computing continues to grow, so does the energy required to power it. Scientists are therefore searching for alternatives that can perform the same tasks while using far less energy. https://phys.org/news/2026-08-magnetic-path-power.html Nanophysics Thu, 13 Aug 2026 10:00:04 EDT news705831481 For dogs with heart disease, a fraction of a centimeter can make a life-changing difference. Veterinarians often rely on chest radiographs to monitor subtle changes in heart size that help determine when treatment should begin. But those measurements can vary from one doctor to the next, making it difficult to know whether a dog's condition is truly changing or whether the difference is simply the result of human interpretation. https://phys.org/news/2026-08-ai-tool-veterinarians-track-heart.html Veterinary medicine Wed, 12 Aug 2026 15:30:01 EDT news705765121 More than 100,000 people are awaiting an organ transplant in the United States, with a new candidate added to the list every 10 minutes. Even if the transplant is carried out successfully, recipients must take immunosuppressive medications, elevating their risk of broader infections, and adhere to a strict lifestyle for the rest of their lives—all while facing the possibility that their body could reject the donated organ at any time. https://phys.org/news/2026-08-hybrid-bioprinter-capillary-networks-narrower.html Biotechnology Wed, 12 Aug 2026 13:40:06 EDT news705752101 Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many practical applications, this has not yet been demonstrated. Research therefore relies heavily on theoretical models and simulations to explore where and under what conditions such an advantage may realistically be achieved in the future. https://phys.org/news/2026-08-quantum-advantage-reassessed-realistic-benchmarks.html General Physics Wed, 12 Aug 2026 09:20:08 EDT news705742802 Capturing carbon or storing hydrogen to combat global warming requires compressing gases into sponge-like porous materials. Until now, gas molecules were thought to adsorb in a disordered manner throughout the pores. But what if invisible gas molecules could be lined up in regular order—like ice crystals or LEGO bricks? https://phys.org/news/2026-08-porous-material-disordered-gas-molecules.html Analytical Chemistry Tue, 11 Aug 2026 18:20:05 EDT news705678721 In the Midwestern summer, humans and plants have to breathe through the heat and humidity. Researchers hope that a retooled crop plant—one with an improved ventilation system within its leaves—could thrive while avoiding drought stress by reducing "crop sweat." Thanks to next-generation imaging technology powered by Argonne National Laboratory's particle collider beamline, a team of scientists now has precise schematics of the leaf's interior and can refine approaches to breeding hardier crop plants. https://phys.org/news/2026-08-ray-analysis-reveals-life-advancing.html Biotechnology Tue, 11 Aug 2026 17:50:01 EDT news705684001 Combining drone data and machine learning can help cover more ground in monitoring forest soil health, University of Alberta research shows. The findings are published in the journal Forest Ecology and Management. Using both tools to map and monitor soil fungal diversity—a key indicator of a healthy forest ecosystem—proved highly effective and could help reduce the need for boots-on-the-ground soil sampling over huge areas of forest, says Dr. Cameron Carlyle, a professor in the Faculty of Agricultural, Life & Environmental Sciences and a co-author of the study. https://phys.org/news/2026-08-machine-forest-soil-fungal-diversity.html Ecology Mon, 10 Aug 2026 19:40:02 EDT news705600242 Scientists—and dog lovers—have long known that dogs are remarkably good at interpreting our laughs, frowns and tears. But the biology behind this ability has remained largely unexplored until now. In a study published in the journal iScience on Aug. 7, researchers peered inside the brains of dogs as they viewed images of various human expressions. The brain scans revealed that dogs process smiles in a unique brain region and, for the first time, provided evidence that dogs can distinguish between negative facial expressions, including anger, sadness and fear. https://phys.org/news/2026-08-mri-dogs-distinguish-human-sadness.html Plants & Animals Mon, 10 Aug 2026 11:00:07 EDT news705246541 How much ice is stored in the world's glaciers?

It is the first predictive model that accounts for how atoms travel through materials during solid-state reactions. Importantly, its predictions provide practical insights into the best recipes for making advanced materials. https://phys.org/news/2026-08-ai-atom-movement-solid-state.html Analytical Chemistry Mon, 03 Aug 2026 18:00:06 EDT news704987485 While Earth's core consists mostly of iron, its density implies that lighter elements are also mixed in. Because hydrogen is abundant in the universe and can mix with iron under certain conditions, scientists suspect it makes up part of the lighter-element composition. Data from earthquakes suggest the inner part of the core also changes with depth, but scientists aren't sure exactly how this occurs. Now, a new study published in the Proceedings of the National Academy of Sciences indicates that hydrogen likely exists in a gradient within the inner and outer core that arises from thermodynamic equilibrium. https://phys.org/news/2026-08-exotic-phase-hydrogen-earth-core.html Earth Sciences Mon, 03 Aug 2026 13:20:01 EDT news704977583 The small mountain streams that feed many of the West's rivers may face a much drier future. A new study led by NAU researchers found that groundwater-fed streamflow, known as base flow, has been steadily declining across headwater watersheds in the western United States since 1950 and could decrease by 45% to 65% by the end of this century if current climate trends continue. https://phys.org/news/2026-07-climate-west-headwaters.html Environment Sun, 02 Aug 2026 14:40:01 EDT news704719021 Most sensors are designed to do only one thing: detect what passes through them. But what if a sensor could do more? To create a new generation of technology, researchers have looked to living systems for inspiration.

While not uncommon, their brightness can make it difficult to accurately measure the galaxies they reside in. This means scientists must use gravitational lensing to assist in analyzing these bright objects, a method that relies on studying how an object's strong gravity bends light around its host galaxy. Yet despite their own powerful gravity, quasars that can act as lenses are rare. https://phys.org/news/2026-07-quasar-lenses-emerge-ai-scan.html Astronomy Mon, 27 Jul 2026 15:20:07 EDT news704377501 Low-level clouds over Earth's oceans play a prominent role in keeping our planet cool by reflecting sunlight away from the surface.
