Neutrinos are among the most abundant particles in the universe, but they are also among the most elusive. Nearly massless, they are produced by nuclear reactions in the sun, exploding stars, particle accelerators and even the decay of radioactive elements on Earth. They interact so weakly with ordinary matter that trillions pass through each person every second without leaving a trace. Studying these ghostly particles could help answer some of the biggest questions in physics, from the nature of dark matter to why matter exists at all. https://phys.org/news/2026-10-spine-machine-trail-ghost-particles.html General Physics Tue, 27 Oct 2026 15:10:01 EDT news712330469 Astronomers identified an exceptionally tiny core that may represent an early stage in the formation of a massive star. Located in an infrared-dark area called Dragon Cloud, the core is nicknamed the "dragon egg." The paper, accepted for publication in Astronomy & Astrophysics, was posted to the arXiv preprint server on Oct. 5. https://phys.org/news/2026-10-alma-dragon-egg-earliest-stages.html Astronomy Fri, 23 Oct 2026 12:50:01 EDT news711976208 An international study involving ICTA-UAB reveals that large energy corporations use corporate sustainability narratives to legitimize wind, solar and hydropower projects that, in practice, exclude communities from fair economic and financial returns and ignore the projects' social and environmental impacts. https://phys.org/news/2026-10-dark-side-energy-transition-renewable.html Economics & Business Thu, 22 Oct 2026 14:40:02 EDT news711894001 A new study led by researchers at the Konkoly Observatory of the HUN-REN Research Centre for Astronomy and Earth Sciences (HUN-REN CSFK) in Budapest has revealed what makes a distant red giant star the most explosively active in the entire Kepler field—and the answer lies in a surprisingly subtle interplay between a close stellar companion, vast dark starspots and a highly efficient internal magnetic dynamo. https://phys.org/news/2026-10-astronomers-uncover-powerful-stellar-flares.html Astronomy Wed, 21 Oct 2026 09:20:06 EDT news711791342 Voltage fluctuations, light fluctuations, temperature fluctuations—any fluctuations are troublesome and thus undesirable. They don't just cause discomfort; in engineering and medical applications, they affect the accuracy of measurements or introduce errors in controls. Even at the minute level of quantum phenomena, fluctuations are considered undesirable. https://phys.org/news/2026-10-forbidden-emissions-graphene-expose-quantum.html Optics & Photonics Mon, 19 Oct 2026 13:40:04 EDT news711626341 Australian researchers and international collaborators have demonstrated a solar-driven approach to convert glycerol, a low-value byproduct of biodiesel production, into hydrogen and higher-value chemicals.

A conversation returns, then thoughts. You bring your attention back to the breath. Sometimes, after many such returns, the effort eases. Thoughts lose their urgency, while awareness remains clear. Less occupies the mind, yet the moment still feels whole. https://phys.org/news/2026-10-meditation-reveal-su3-symmetry-universe.html General Physics Tue, 13 Oct 2026 17:40:08 EDT news711105159 For many years, the simplest view of dark energy has been that it remains unchanged. Throughout cosmic history, the mysterious ingredient believed to drive the universe's accelerated expansion is thought to have behaved in the same way at every epoch. However, an increasing number of observations are challenging this idea. https://phys.org/news/2026-10-alternative-gravity-theory-explanation-dark.html Astronomy Mon, 12 Oct 2026 13:40:14 EDT news711029618 A new technique developed at Imperial College London measures oxygen production in real time, revealing hidden losses in solar water splitting. The researchers found that electrical current did not always correspond to oxygen generation in hematite, one of the most widely studied materials in the field, revealing a previously unknown limitation in the reaction. https://phys.org/news/2026-10-real-oxygen-expose-hidden-losses.html Analytical Chemistry Thu, 08 Oct 2026 17:30:01 EDT news710697721 Using data from the DESI Legacy Imaging Surveys, with help from artificial intelligence, an international team of scientists has discovered 70 new gravitational lenses—rare cosmic alignments that act as natural magnifying glasses. The new lenses further expand one of the largest collections of confirmed lenses to date and will allow scientists to study dark matter, galaxy evolution and the structure of the universe. https://phys.org/news/2026-10-largest-2d-universe-scientists-gravitational.html Astronomy Thu, 08 Oct 2026 09:40:12 EDT news710669701 Modern technological breakthroughs like lasers, MRI scanners, semiconductors and quantum computers rest on the study of quantum mechanics.

But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's not the end of the weirdness. Their formation could have been even stranger if it occurred in a universe with a dark dimension, which is another theoretical construct. It posits that our space includes a hidden extra spatial dimension. https://phys.org/news/2026-10-tiny-ancient-black-holes-dimensional.html Astronomy Mon, 05 Oct 2026 12:40:16 EDT news710412892 Dark matter could be a type of matter in the universe that does not emit, absorb or reflect detectable light and appears to interact very weakly with regular matter. Although physicists have observed gravitational effects attributed to dark matter, they have not yet been able to determine what it is made of. https://phys.org/news/2026-09-gamma-ray-limits-dark-annihilation.html Astronomy Sun, 04 Oct 2026 15:20:01 EDT news709978528 Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 "bulgeless" galaxies—systems with little or no central stellar bulge. Their paper, published in Monthly Notices of the Royal Astronomical Society, suggests that galaxies without a central bulge grow black holes just as effectively as galaxies that have one—a surprising sign that black holes don't need galaxy mergers to grow normally. https://phys.org/news/2026-10-black-holes-quietly-galaxies-violent.html Astronomy Fri, 02 Oct 2026 15:20:02 EDT news710150297 Broccoli grown under magenta solar panels absorbed sunlight more efficiently than plants grown out in the open, according to a study to be published Oct. 2 in Cell Reports Physical Science. https://phys.org/news/2026-10-multitasking-magenta-solar-panels-farms.html Biotechnology Fri, 02 Oct 2026 11:00:05 EDT news710063403 Anak Krakatau, which means Child of Krakatoa, has been active sporadically since it emerged from the sea at the beginning of the last century in the caldera formed after the 1883 eruption of Mount Krakatoa. https://phys.org/news/2026-10-earthcare-view-volcanic-plume-boosts.html Earth Sciences Thu, 01 Oct 2026 16:20:20 EDT news710075761 The center of the Milky Way galaxy is a chaotic place. In addition to the 4-million-solar-mass black hole known as Sagittarius A* (Sgr A*), the region is full of gas, dust, strong magnetic fields and stars in various stages of life—from birth to death. https://phys.org/news/2026-10-cleaner-ray-view-galactic-center.html Astronomy Thu, 01 Oct 2026 10:20:32 EDT news710064541 The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has shown for the first time that it can detect the faint glow of hydrogen gas from deep in the universe's past using only its own data. https://phys.org/news/2026-09-hydrogen-distant-dark-energy.html Astronomy Mon, 28 Sep 2026 19:00:04 EDT news709825988 Researchers at the DarkSide collaboration have unveiled results from a seven-year experiment that tested whether dark matter particles could exist as composites of smaller, elementary particles. While the search turned up no direct evidence of this "ultraheavy nuclear" dark matter, results from the DarkSide-50 detector could lay the groundwork for future experiments, helping physicists work out whether dark matter has an internal structure. https://phys.org/news/2026-09-darkside-detector-nuclear-dark.html General Physics Mon, 28 Sep 2026 12:30:01 EDT news709811061 Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas. Every large galaxy, including the Milky Way, is wrapped in a huge envelope of gas called the circumgalactic medium, or CGM. This reservoir of raw material stretches 10–20 times the size of the visible portion of the galaxy. https://phys.org/news/2026-09-black-hole-jets-galaxies-visible.html Astronomy Sat, 26 Sep 2026 17:00:01 EDT news709472146 The cosmic microwave background (CMB) is the universe's oldest light, leftover thermal radiation from about 380,000 years after the big bang. Maps of the CMB offer a picture of the "baby universe" as it was 13.8 billion years ago. https://phys.org/news/2026-09-universe-oldest.html Astronomy Thu, 24 Sep 2026 13:30:01 EDT news709473241 Unlike electric charge, as far as we know all mass is positive, and positive masses attract one another. Could negative mass exist, and if so, what would be the ramifications? https://phys.org/news/2026-09-negative-mass.html General Physics Wed, 23 Sep 2026 09:20:12 EDT news709372229 The origins of the earliest life on Earth, prior to the rise of oxygen and photosynthesis, remain a mystery. Graveyards in brine pools at the bottom of the Red Sea may hold some answers. https://phys.org/news/2026-09-briny-death-pools-clues-early.html Earth Sciences Tue, 22 Sep 2026 13:00:01 EDT news709290788 A drop of coffee on a tabletop often leaves a dark ring behind. This everyday mark is a reminder that a drying droplet is not passive: As water evaporates, it can transport the particles suspended inside it toward the edge. Scientists call this the coffee-ring effect. For inkjet printing and surface coatings, however, a ring is often exactly what engineers do not want. They need the material to land in a controlled, predictable pattern. https://phys.org/news/2026-09-spider-webs-mosaics-nanosheets-graphene.html Nanophysics Mon, 21 Sep 2026 18:00:05 EDT news709199310 Around 631,000 years ago—a geological blink of an eye—catastrophe unfolded in what is now northwestern Wyoming, U.S. During what is thought to have been a series of immense volcanic eruptions, life within hundreds of kilometers of the blasts was shattered. Ash was dispersed across much of North America, and the effects were felt worldwide. This was a super-eruption of the massive volcanic system located in what is now Yellowstone National Park. https://phys.org/news/2026-09-humanity-blowbyblow-account-yellowstone-supervolcano.html Earth Sciences Mon, 21 Sep 2026 10:40:06 EDT news709205583 An international research team has reported the first experimental investigation of a nuclear physics reaction essential for understanding how the element strontium is produced in stars—specifically in stellar environments where traditional explanations for its formation fall short. The study, published June 8 in Communications Physics, reports that the team used indirect experimental techniques to extract previously inaccessible information about how an isotope of a separate element—krypton—absorbs, or captures, neutrons. https://phys.org/news/2026-09-krypton-narrow-key-gap-stellar.html Astronomy Thu, 17 Sep 2026 18:40:06 EDT news708873901 When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, known as phonons. They may also collide with one another. Frustratingly, a conventional temperature test warms the electrons and the lattice together, so the effects arrive tangled in the same resistance measurement. https://phys.org/news/2026-09-hot-electrons-reveal-electronic-collisions.html Condensed Matter Wed, 16 Sep 2026 19:40:01 EDT news708787802 New research shows how artificial intelligence, combined with advanced experimental science, can help find "hidden" and unexplored proteins in the human body and reveal what they actually do, according to a new study published in Nature. https://phys.org/news/2026-09-ai-hidden-human-proteins-reveals.html Biotechnology Fri, 11 Sep 2026 17:40:05 EDT news708351781
