TU Wien and the University of Innsbruck have now discovered an unexpected reaction pathway that makes it possible to synthesize natural gas, or methane (CH4), using CO2 that was previously captured from exhaust gas streams or directly from the air. In this way, methane can become climate-neutral overall. https://phys.org/news/2026-06-unexpected-pathway-climateneutral-methane-nickelzirconia.html Materials Science Mon, 29 Jun 2026 19:40:03 EDT news701964661 The world's most powerful particle accelerator will shutter operations Monday for four years of renovations to dramatically boost its collision capacity and the potential for unlocking one of the greatest mysteries of the universe: dark matter. https://phys.org/news/2026-06-world-largest-particle-smasher-halts.html General Physics Sat, 27 Jun 2026 15:29:47 EDT news701792967 It's the time of year when parents are thinking of registering their children for kindergarten in September—a much-anticipated moment in the lives of many parents and their young ones. https://phys.org/news/2026-06-ways-kindergarten-lays-foundation-lifelong.html Social Sciences Tue, 16 Jun 2026 11:00:01 EDT news700812001 The space between stars may seem like a barren desert, but over the past few decades scientists have been finding all sorts of interesting chemicals in it. From the precursors to proteins to the building blocks of cell membranes, there has been discovery after discovery of new molecules in the giant gas clouds between the stars. Now, a new paper available on the arXiv preprint server details the discovery of the first-ever four-carbon sugar in the interstellar medium (ISM), and it is another brick on the path to understanding how life on Earth first developed. https://phys.org/news/2026-06-astronomers-carbon-sugar-deep-space.html Astronomy Wed, 10 Jun 2026 09:20:01 EDT news700300081 This April, humanity had front-row seats to space as the Artemis II Orion spacecraft transmitted crystal-clear footage of its historic journey around the moon from more than 250,000 miles (about 402,000 kilometers) back to Earth at speeds on par with home internet connections. https://phys.org/news/2026-06-artemis-ii-livestreamed-def-videos.html Space Exploration Mon, 08 Jun 2026 10:40:03 EDT news700133941 On May 22, 2026, the Pentagon released a second batch of previously classified photos and videos showing what appear to be unexplained flying objects. These file dumps were the culmination of a process that was set in motion back in July 2023, when a group of government whistleblowers testified before Congress that the U.S. government was secretly in possession of extraterrestrial spacecraft and suspected alien body parts. https://phys.org/news/2026-05-aliens-earth-aerospace-scientist-interstellar.html Astrobiology Wed, 27 May 2026 10:01:14 EDT news699094082 Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron produced in stellar explosions. This has now been confirmed by an international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) through the analysis of Antarctic ice tens of thousands of years old. From the steady but time-varying influx, the researchers conclude that the radioactive isotope has been stored within the cloud since a long-past stellar explosion. The results have been published in the journal Physical Review Letters. https://phys.org/news/2026-05-stardust-antarctic-ice-cores-earth.html Astronomy Sun, 17 May 2026 15:20:01 EDT news697946932 We're focusing on space news this week, but we did cover the usual amount of local news down here in Earth's gravity well: A new Tokamak reactor regime sustained stable plasma fusion for one full minute. An anomaly in global sea level rise turns out to be due to deep ocean heating.

Covering regions in our Milky Way galaxy more than 600 light-years across, the ice was found inside giant molecular clouds—vast regions of gas and dust where dense clumps of matter collapse under gravity, giving birth to stars. A study describing these findings was published Wednesday in The Astrophysical Journal. https://phys.org/news/2026-04-interstellar-glaciers-nasa-spherex-vast.html Astronomy Wed, 15 Apr 2026 19:20:04 EDT news695485741 When created at the nanoscale, materials can resemble shapes like stars, rods or even pyramids. These particle shapes, also known as the morphologies of a solid, make for more than just interesting images under a microscope—they can determine how the material behaves, sometimes in dramatic ways. University at Buffalo researchers have demonstrated this phenomenon by creating the first-ever star-shaped vanadyl hydroxide (VOOH) and shown that this shape can fundamentally alter how the material stores energy. https://phys.org/news/2026-04-pretty-picture-star-nanomaterial-energy.html Nanophysics Tue, 07 Apr 2026 12:40:04 EDT news694776061 Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios.

The journal Science published the research led by Emory University and the New College of Florida. The findings suggest that seals and sea lions may have vocal flexibility as a side effect of developing a brain "bypass" for voluntary breath control. This same bypass allowed them to adapt to aquatic life. https://phys.org/news/2026-03-sea-lions-clues-evolution-vocalization.html Plants & Animals Thu, 12 Mar 2026 17:10:01 EDT news692553061 During their search for food, most insects head specifically for the flowers that promise the highest reward.

Rubin Observatory in Chile, in real time and with unprecedented precision. Minutes after each image is taken, Fink receives, processes, enriches, and cross-references the data with existing datasets. This allows even the faintest variations in detected light to be characterized with remarkable accuracy. The data is then stored, classified, and shared with users—scientists and astronomy enthusiasts—in a concise and targeted manner. https://phys.org/news/2026-02-closer-stars-fink-french-tool.html Astronomy Thu, 26 Feb 2026 14:50:01 EST news691339681 To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, entails comparing the light signals originating from distant objects and picked up by different telescopes that are at different locations, then reconstructing images using computational techniques. https://phys.org/news/2026-02-quantum-entanglement-link-distant-telescopes.html Optics & Photonics Fri, 20 Feb 2026 08:00:05 EST news690725074 For life to develop on a planet, certain chemical elements are needed in sufficient quantities. Phosphorus and nitrogen are essential. Phosphorus is vital for the formation of DNA and RNA, which store and transmit genetic information, and for the energy balance of cells. Nitrogen is an essential component of proteins, which are needed for the formation, structure, and function of cells. Without these two elements, no life can develop out of lifeless matter. https://phys.org/news/2026-02-small-planets-suitable-life.html Astrobiology Mon, 09 Feb 2026 13:12:42 EST news689865122 Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated through the twin 2.4-mile-circumference rings of the Relativistic Heavy Ion Collider (RHIC) and crashed into one another at nearly the speed of light inside the collider's two house-sized particle detectors, STAR and sPHENIX. RHIC, a nuclear physics research facility at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has been smashing atoms since the summer of 2000.

Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and we die, in exactly that order. We plan our lives around time, measure it obsessively and experience it as an unbroken flow from past to future. It feels so obvious that time moves forward that questioning it can seem almost pointless. https://phys.org/news/2026-01-fundamental-reality-quiet-revolution-physics.html Quantum Physics Thu, 29 Jan 2026 11:20:54 EST news688908002 Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter spacecraft has discovered that a solar flare is triggered by initially weak disturbances that quickly become more violent.
