Trawling restrictions not only benefit fish and shellfish; anemones and corals are also becoming more common, according to a new study from the University of Gothenburg. Twenty-six years of underwater videos from the depths of the Koster Sea also show long-term changes in the ecosystem as the water becomes warmer. /news/2025-10-unique-videos-trawling-restrictions-life.html Plants & Animals Ecology Fri, 03 Oct 2025 09:20:15 EDT news678701997 On Sept. 25, the Donald Trump administration in the United States again extended the TikTok ban-or-divest law, possibly for the last time. The latest extension to the law, which was passed in 2024 by the Joe Biden administration, includes a deal to transfer TikTok to American owners as a condition required to avoid a ban. /news/2025-10-opinion-american-tiktok-doesnt-platform.html Economics & Business Political science Thu, 02 Oct 2025 14:18:04 EDT news678633481 Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve very different scales or highly sensitive parameters), they become extremely difficult to solve. This is especially relevant in inverse problems, where scientists try to deduce unknown physical laws from observed data. /news/2025-10-ai-techniques-excel-complex-equations.html General Â鶹ÒùÔºics Thu, 02 Oct 2025 13:20:01 EDT news678629719 The most distant and most powerful "odd radio circle" (ORC) known so far has been discovered by astronomers. These curious rings are a relatively newly identified astronomical phenomenon, having been detected for the first time just six years ago. Only a handful of confirmed examples are known—most of which are 10–20 times the size of our Milky Way galaxy. /news/2025-10-powerful-odd-radio-circle-date.html Astronomy Thu, 02 Oct 2025 09:45:35 EDT news678617123 Though it might seem like science fiction, scientists are working to build nanoscale molecular machines that can be designed for myriad applications, such as "smart" medicines and materials. But like all machines, these tiny devices need a source of power, the way electronic appliances use electricity or living cells use ATP (adenosine triphosphate, the universal biological energy source). /news/2025-10-rechargeable-powers-nanoscale-molecular-machines.html Bio & Medicine Nanophysics Wed, 01 Oct 2025 15:40:04 EDT news678552001 With a pioneering, comprehensive approach on a global scale, Brazilian researchers have developed a methodology that allows them to project the physiological responses of herds of different production animal species to the impacts of climate change between 2050 and 2100. /news/2025-10-global-analysis-livestock-vulnerability-climate.html Plants & Animals Agriculture Wed, 01 Oct 2025 15:05:17 EDT news678549911 Researchers from the National University of Singapore (NUS) have successfully applied cryo-electron microscopy (cryo-EM) to unveil the molecular structures of critical protein machines that transport lipids and maintain the outer membrane (OM) barrier of Gram-negative bacteria. /news/2025-10-cryo-em-reveals-protein-complexes.html Cell & Microbiology Molecular & Computational biology Wed, 01 Oct 2025 15:00:02 EDT news678549389 A team of researchers from the University of Minnesota Twin Cities College of Science and Engineering and the University of Houston's Cullen College of Engineering has discovered and measured the fraction of an electron that makes catalytic manufacturing possible. /news/2025-10-energy-fraction-electron-catalysis.html Analytical Chemistry Materials Science Wed, 01 Oct 2025 14:56:23 EDT news678549372 Oil spills can be among the most devastating environmental disasters, with the potential to severely damage marine ecosystems, disrupt coastal communities, and impose lasting economic damage. Traditional numerical models, such as MEDSLIK-II, simulate the movement and transformation of oil particles in seawater, but their accuracy has been limited by dependence on expert judgment for tuning critical physical parameters. This manual calibration process, while informed by experience, is not always able to capture the complexity and variability of real-world ocean and atmospheric conditions. /news/2025-10-ai-powered-oil-emergency-response.html Environment Wed, 01 Oct 2025 13:12:50 EDT news678543166 A team of researchers at the University of Miami has developed a global atmospheric modeling framework that blends powerful research capabilities with accessibility for students and scientists alike. /news/2025-10-python-based-framework-climate-dynamics.html Earth Sciences Environment Wed, 01 Oct 2025 12:14:04 EDT news678539641 University of Michigan and Carnegie Mellon University researchers have developed a new tool that makes greener chemistry more accessible.

Studies using eye-tracking, which record eye movements during reading, have suggested that word length, frequency, and predictability from context are the three primary factors influencing word processing during English reading. While these factors are known to affect non-native English readers as well, it has remained unclear which is the most decisive. /news/2025-09-factors-affecting-word-language-english.html Education Tue, 30 Sep 2025 15:25:02 EDT news678464701 Long-term weather forecasting is a difficult task, partly because weather systems are inherently chaotic. Though mathematical equations can approximate the underlying physics of weather, tiny inaccuracies that grow exponentially as a model progresses in time limit most physics-based forecasts to 2 weeks or less. /news/2025-09-algorithm-weather-ai.html Earth Sciences Environment Tue, 30 Sep 2025 15:10:07 EDT news678463250 Whether an asteroid is spinning neatly on its axis or tumbling chaotically, and how fast it is doing so, has been shown to be dependent on how frequently it has experienced collisions. The findings, presented at the recent EPSC-DPS2025 Joint Meeting in Helsinki, are based on data from the European Space Agency's Gaia mission and provide a means of determining an asteroid's physical properties—information that is vital for successfully deflecting asteroids on a collision course with Earth. /news/2025-09-gaia-mystery-asteroids-probe-interiors.html Planetary Sciences Tue, 30 Sep 2025 13:30:07 EDT news678457179 Researchers from The University of New Mexico and Los Alamos National Laboratory have developed a novel computational framework that addresses a longstanding challenge in statistical physics. /news/2025-09-ai-tensor-network-based-framework.html General Â鶹ÒùÔºics Condensed Matter Tue, 30 Sep 2025 13:12:04 EDT news678456722 Air quality in America's largest cities has steadily improved thanks to tighter regulations on key sources of particulate pollution.

One of the most destructive aspects of seismic events in Tokyo is a geological phenomenon known as soil liquefaction. This occurs when the intense shaking from an earthquake causes saturated, loosely packed soil to temporarily lose its strength and stiffness, essentially causing the ground to behave like a liquid. /news/2025-09-machine-sharpens-earthquake-tokyo.html Earth Sciences Tue, 30 Sep 2025 10:14:04 EDT news678446041 Generative AI tools such as ChatGPT, Gemini and Claude are now used by students and teachers at every level of education. /news/2025-09-generative-ai-outsourcing-production-knowledge.html Education Mon, 29 Sep 2025 13:10:01 EDT news678369172 Researchers at Georgia Tech have analyzed the seasonal differences of sulfate aerosols—a major pollutant in the United States—to examine the long-term impact from sulfur dioxide (SOâ‚‚) emission reductions since the enactment of the Clean Air Act amendments in 1990. /news/2025-09-decades-full-impact-air-pollution.html Earth Sciences Environment Mon, 29 Sep 2025 11:45:04 EDT news678365102 Researchers from FishEye Collaborative, a conservation-technology nonprofit, Cornell University, and Aalto University have developed a new tool that combines underwater sound recording and 360° video to pinpoint the sounds made by individual fish.
