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 In November 1857, during a séance in Jersey City, the medium Leah Brown claimed her body produced luminous particles. So intense was the luminosity emanating from her, she recalled in her memoir, that it almost burned her hands. She rinsed her hands under a tap and then pushed them into the damp earth outside. https://phys.org/news/2026-10-ghoul-chemical-tool-toxic-chemistry.html Other Mon, 26 Oct 2026 18:50:01 EDT news712233694 A U.S. startup has booked two Indian rocket launches to test a planned service no company has sold before: sunlight at night. https://phys.org/news/2026-10-american-startup-sunlight-dark.html Economics & Business Mon, 26 Oct 2026 11:40:02 EDT news712224263 South Africa endured its worst year of load shedding (scheduled power cuts by the country's utility, Eskom) in 2023. The power went off on 335 of the year's 365 days, often several times a day.

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.

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.
