They can be co-opted to create "gene switches" that hold significant potential for understanding gene expression and for therapeutic applications, particularly for the noninvasive treatment or management of genetic disorders. https://phys.org/news/2026-08-molecular-electromagnetic-sensor-enable-remote.html Biotechnology Mon, 17 Aug 2026 19:40:04 EDT news706196881 A current system in the Atlantic Ocean that shapes regional climates and distributes ocean nutrients also serves as a control knob to help regulate temperatures across the planet, new research has found. https://phys.org/news/2026-08-weakening-atlantic-ocean-current-earth.html Earth Sciences Mon, 17 Aug 2026 18:10:01 EDT news706206001 What is heat, and what is useful work if a machine consists only of an atom and light particles? In modern quantum technologies, this kind of question connects thermodynamics with quantum physics. Researchers at the University of Basel, Switzerland, have developed a theoretical approach that can reconcile both theories. https://phys.org/news/2026-08-quantum-links-atom-photon-thermodynamics.html General Physics Mon, 17 Aug 2026 17:30:02 EDT news706204501 Climate change presents animals and plants with a fundamental challenge: What can they do when their established habitats become increasingly warm? They can adapt to the changing conditions—or move to areas where the climate remains suitable for them. https://phys.org/news/2026-08-butterflies-higher-ground-redraws-alpine.html Plants & Animals Mon, 17 Aug 2026 17:20:01 EDT news706190401 Tick-borne diseases are on the rise in the United States. Lyme disease is the most commonly reported, with nearly half a million people diagnosed each year. Caused by the bacterium Borrelia burgdorferi, it is most often spread by bites from blacklegged ticks. Lyme can be treated with antibiotics, but if untreated, infection can spread to the joints, heart and nervous system, and some people can experience persistent symptoms. https://phys.org/news/2026-08-year-ecological-lyme-disease.html Ecology Mon, 17 Aug 2026 15:00:12 EDT news705920766 It's nearly 170 million years old. It's more than 2.5 times the size of Earth.

The finding opens a vast region for experimental searches and could change the hunt for dark matter. https://phys.org/news/2026-08-early-universe-plasma-dark-photons.html Astronomy Sat, 15 Aug 2026 12:40:01 EDT news705910291 Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all satellites orbiting the planet while orbiting retrograde compared with Neptune's rotation. The predominant theory is that Triton is a captured Kuiper Belt object that caused a major disruption in Neptune's early moon system. Now, a new study published in Science Advances provides spectroscopic evidence to support this theory. https://phys.org/news/2026-07-neptune-tiny-moons-story-triton.html Planetary Sciences Sat, 15 Aug 2026 11:20:01 EDT news704628891 According to a new study led by researchers from Brazil and Germany, the main system that transports heat from one end of the Atlantic Ocean to the other may undergo sudden changes in intensity driven by climate change similar to what we are experiencing now, even when it is already weakened. https://phys.org/news/2026-08-sediments-brazil-northeast-coast-reveal.html Earth Sciences Fri, 14 Aug 2026 13:00:04 EDT news705931022 Three factors—spectacular images, a high death toll and strong personal ties—make it more likely that the media in one country will report on a natural disaster in another, according to a study by the University of Bonn, the University of Warwick and Imperial College London, which has been published in the journal Nature Human Behaviour. https://phys.org/news/2026-08-climate-driven-droughts-rarely-international.html Environment Fri, 14 Aug 2026 10:20:01 EDT news705921028 The Huashan rock art landscape in southern China, close to the border with Vietnam, is a remarkable UNESCO World Heritage site. Thousands of images are painted on river cliffs across more than 80 locations stretching 260 kilometers (162 miles). They depict people, musical instruments, boats, animals, weapons and many other figures, and date back at least 2,000 years. https://phys.org/news/2026-08-human-blood-ancient-chinese-art.html Archaeology Fri, 14 Aug 2026 10:00:01 EDT news705842919 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 Detecting water where none remains today: Neutron and X-ray tomography make it possible. In an international study conducted with the participation of the Paul Scherrer Institute PSI, researchers have brought to light macroscopic hydrogen-rich regions inside a Martian meteorite. The findings provide evidence for early water-rock interactions on Mars. https://phys.org/news/2026-08-dry-meteorite-mars.html Astrobiology Thu, 13 Aug 2026 15:00:01 EDT news705841861 Animals struggle to cool down in extreme heat and high humidity, and heat stress is rising in many regions around the world. This is especially true for people in tropical countries, including populous India. In a new paper in AGU Advances, researchers characterize the extent of India's "uncompensable heat stress" and project how the problem could worsen in the future. https://phys.org/news/2026-08-india-uncompensable-stress-monsoon-season.html Earth Sciences Thu, 13 Aug 2026 14:20:05 EDT news705839127 If you want to know how rapidly pumping carbon dioxide into the atmosphere will affect future forest ecosystems, you have to look into the distant past. The researchers behind a new study published in Science have done just that, reconstructing the forest canopy of 56 million years ago, during a massive and abrupt emission of carbon into the atmosphere during the Paleocene-Eocene Thermal Maximum (PETM). For the first time, the study's authors used fossilized leaf cells to reconstruct the tree canopy of the PETM, Earth's most recent period of comparable global warming, with chilling implications for our near future. https://phys.org/news/2026-08-paleontologists-reconstruct-forests-million-years.html Ecology Thu, 13 Aug 2026 14:00:06 EDT news705678121 Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin. In new research published in the journal Science Advances, scientists have identified another type of heat wave that they call a "snow-eater." https://phys.org/news/2026-08-category-western-snowpack-faster.html Earth Sciences Thu, 13 Aug 2026 12:40:07 EDT news705832968 A popular myth about black holes is that they act like giant cosmic vacuum cleaners, sucking in everything around them. But Wladimir Lyra's research found a new mechanism around supermassive black holes that is more like a cosmic nursery, giving birth to planets more massive than Jupiter. https://phys.org/news/2026-08-supermassive-black-holes-massive-planets.html Astronomy Thu, 13 Aug 2026 09:11:08 EDT news705831033 For several years, climate scientists have shown that the Atlantic Meridional Overturning Circulation (AMOC) could come to a halt if the world warms too much. New research from Utrecht University shows that this picture is incomplete: The pace of warming also determines whether the AMOC stays stable. https://phys.org/news/2026-08-rapid-atlantic-circulation-2c-slower.html Earth Sciences Thu, 13 Aug 2026 05:00:06 EDT news705752641 Altermagnetism is a new, third type of magnetism of great interest for spin-transport applications like computer memory. If properly harnessed, it could combine the benefits of the two existing types of magnetism, ferromagnetism and antiferromagnetism, ultimately reducing or eliminating heat during information transfer and increasing the ability to miniaturize next-generation technologies. Rice University's Pengcheng Dai recently published a paper in Physical Review X describing the first successful efforts to put a proposed altermagnetic material into a single magnetic-domain state, allowing the research team to characterize the material's intrinsic magnetic structure. https://phys.org/news/2026-08-uniaxial-strain-reveals-tune-electron.html Condensed Matter Thu, 13 Aug 2026 02:39:51 EDT news705807532 MXenes are two-dimensional materials made of very thin layers of metals, measured on the atomic scale. They conduct electricity well and have surfaces that can easily interact with other materials, making them excellent candidates for advanced electronic devices, computers and aerospace coatings. The only problem is that, until a recent innovation by James Tour's lab at Rice University, building them required a lengthy, acid-filled process called liquid-phase chemical etching. https://phys.org/news/2026-08-ultrafast-joule-significantly-mxene.html Nanomaterials Wed, 12 Aug 2026 18:30:04 EDT news705773701 Scorching heat waves, severe cold snaps and other extreme weather events are limiting where species can exist—and affecting biodiversity estimates—for more than 500 North American bird species, according to a new, Yale–led study. The issue is particularly acute in the Great Plains and southwestern regions of the United States, where species ranges and total species counts are significantly overestimated when variable and extreme weather are not considered, the study says. https://phys.org/news/2026-08-severe-weather-key-predictor-bird.html Ecology Wed, 12 Aug 2026 16:40:06 EDT news705755761 Every tomato begins with a flower. But before a fruit can grow, an intricate sequence of events must happen in perfect order. The flower's male and female organs must develop together, pollen must be released at exactly the right time, and fertilization must occur. https://phys.org/news/2026-08-genetic-tomatoes-fruit-cold-weather.html Biotechnology Wed, 12 Aug 2026 16:10:01 EDT news705767641 Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing livestock farming and agriculture. Because these methods also require energy input, they are popularly called "power-to-protein" and "power-to-vitamin" processes. https://phys.org/news/2026-08-microbes-protein-vitamin-b9-commercially.html Biotechnology Wed, 12 Aug 2026 15:40:07 EDT news705754983 For thousands of years, the Anindilyakwa people have lived in deep connection with the waters surrounding Groote Eylandt, a remote island in the Gulf of Carpentaria. https://phys.org/news/2026-08-rangers-scientists-vulnerable-reefs-remote.html Plants & Animals Wed, 12 Aug 2026 14:00:01 EDT news705671161 Researchers say a spike in temperatures during an ice age 304 million years ago could inform what climate scientists are learning about rapidly changing conditions today. https://phys.org/news/2026-08-late-paleozoic-ice-age-event.html Earth Sciences Tue, 11 Aug 2026 18:00:01 EDT news705672841 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 Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA's space telescopes.
