In a new open-access study that I published with my late colleague Kostya Trachenko from Queen Mary University of London, I propose a surprisingly simple nonlinear mathematical equation that unifies 12,000 years of human population growth and points to stark possible futures if global environmental crises intensify. https://phys.org/news/2026-05-mathematical-global-population.html Mathematics Mon, 25 May 2026 10:00:02 EDT news698921136 Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome. Those interactions depend on the ability of chromatin—a mix of DNA and proteins—to move around within a crowded space. In a new study, MIT researchers have measured chromatin movement at timescales ranging from hundreds of microseconds to hours, allowing them to rigorously quantify those dynamics for the first time. https://phys.org/news/2026-05-chromatin-tracking-reveals-motion-modes.html Cell & Microbiology Mon, 04 May 2026 09:00:01 EDT news697101841 The electrons that power our society flow left and right through the circuitry in our electronics, back and forth along the transmission lines that make up our power grid, and up and down to light up every floor of every building. But the electrons in newly discovered "moiré crystals" move in much stranger ways. They can move left and right, back and forth, or up and down in our three-dimensional world, but these electrons also act as if they can teleport in and out of a mysterious fourth dimension of space that is perpendicular to our perceivable reality. https://phys.org/news/2026-04-electrons-moir-crystals-explore-higher.html Condensed Matter Mon, 06 Apr 2026 10:00:03 EDT news694685941 Researchers studying the soft-bodied Ediacaran biotas of the world generally accept that there are three distinct assemblages. The 575–560-million-year-old (Ma) Avalon Assemblage is best known from the Ediacaran of Newfoundland, Canada, characterized by the weird and wonderful fractal Rangeomorpha like Charnia that thrived in the deep, dark waters around the ancient continent of Avalonia. The 560–550-Ma White Sea Assemblage is best known from shallow marine rocks of Australia, Russia, and China, marking the acme of Ediacaran biodiversity and including some famous animal ancestors such as Dickinsonia and Kimberella. And the 550–538-Ma Nama Assemblage is a low-diversity biota that persisted until the extinction event preceding the Cambrian Radiation event at 538 Ma. https://phys.org/news/2026-02-exceptionally-million-year-site-avalon.html Paleontology & Fossils Thu, 26 Feb 2026 18:00:02 EST news691330727 In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst examine a longstanding, paradoxical thought experiment in statistical physics and cosmology known as the "Boltzmann brain" hypothesis—the possibility that our memories, perceptions, and observations could arise from random fluctuations in entropy rather than reflecting the universe's actual past. The work is published in the journal Entropy. https://phys.org/news/2026-01-memories-illusions-disentangles-boltzmann-brain.html General Physics Wed, 21 Jan 2026 15:10:01 EST news688230162 In Earth's fossil record, soft-bodied organisms like jellyfish rarely stand the test of time. What's more, it's hard for any animal to get preserved with exceptional detail in sandstones, which are made of large grains, are porous, and commonly form in environments swept by rough storms and waves. But about 570 million years ago, in a geologic time interval called the Ediacaran period, strange-looking, soft-bodied organisms died on the seafloor, were buried in sand, and fossilized in incredible detail. https://phys.org/news/2026-01-strange-ancient-remarkable-fossils.html Paleontology & Fossils Thu, 08 Jan 2026 13:35:40 EST news687101701 When a gas is highly energized, its electrons get torn from the parent atoms, resulting in a plasma—the oft-forgotten fourth state of matter (along with solid, liquid, and gas). When we think of plasmas, we normally think of extremely hot phenomena such as the sun, lightning, or maybe arc welding, but there are situations in which icy cold particles are associated with plasmas. Images of distant molecular clouds from the James Webb Space Telescope feature such hot–cold interactions, with frozen dust illuminated by pockets of shocked gas and newborn stars. https://phys.org/news/2025-12-icy-hot-plasmas-fluffy-electrically.html Plasma Physics Mon, 08 Dec 2025 10:02:59 EST news684410561 Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in school, where we learn about its use in the context of a circle. More recently, scientists have developed supercomputers that can estimate up to trillions of its digits. https://phys.org/news/2025-12-ramanujan-formulae-pi-modern-high.html General Physics Wed, 03 Dec 2025 08:07:20 EST news683971621 While atmospheric turbulence is a familiar culprit of rough flights, the chaotic movement of turbulent flows remains an unsolved problem in physics.

Is it the method or the creator? Does it need a color palette and oil paints, or a canvas laid flat on the floor and paint splattered across it? Does it require a critically acclaimed painter, or a toddler with crayons? And when it comes to the artist, can we even reliably tell if an artwork has been created by children or adults? https://phys.org/news/2025-11-kid-jackson-pollock-famous-child.html General Physics Thu, 20 Nov 2025 00:00:02 EST news682704661 Researchers have for the first time created a reconfigurable polariton 2D quasicrystal.
