The NASA/ESA/CSA James Webb Space Telescope has unveiled numerous stars formerly hidden by clouds of dust in a stellar nursery known as NGC 7129—a cauldron of cosmic creation, 3,300 light-years from Earth. Webb captured infrared light, which pierces through the dense matter that scatters or absorbs other types of light. This region, rife with stellar objects in different stages of their lives, offers an opportunity to explore how stars shape their surroundings. https://phys.org/news/2026-10-webb-captures-commotion-nebula-stellar.html Astronomy Tue, 06 Oct 2026 13:40:01 EDT news710501821 Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst occurred at a redshift of 0.8577, and the activity lasted about 27 days in the burst's own rest frame—around 20 days longer than the previous record. The paper, posted to the arXiv preprint server on Sept. 18, explores different mechanisms that could be powering this puzzling burst. https://phys.org/news/2026-10-gamma-ray-stayed-month-previous.html Astronomy Tue, 06 Oct 2026 13:20:14 EDT news710505906 Aerosols are small particles suspended in our atmosphere.

But even well-insulated tanks cannot completely prevent heat from entering. As the liquid warms, hydrogen evaporates and pressure builds, leading to boil-off losses during storage and transport. https://phys.org/news/2026-09-rethinking-liquid-hydrogen-storage-metal.html Analytical Chemistry Tue, 29 Sep 2026 18:40:01 EDT news709916342 A new technique for controlling optical components with light could help usher in a generation of high-efficiency signal-processing technology that could drive futuristic applications such as holographic video. https://phys.org/news/2026-09-dyed-liquid-crystals-enable-optical.html Nanophysics Tue, 29 Sep 2026 17:20:16 EDT news709915321 The research group at the Istituto Italiano di Tecnologia in Pontedera (Pisa), led by Gianni Ciofani, has developed new organic nanoparticles that combine multiple therapeutic functions in a single material for the first time. https://phys.org/news/2026-09-dopamine-based-nanotubes-combine-electrical.html Bio & Medicine Mon, 28 Sep 2026 19:40:08 EDT news709831081 A tiny device that can be reprogrammed using a laser could lead to adaptable devices for computing, imaging and telecommunications. Most devices are built to perform a particular job. If you want them to do something different, you generally need to replace a component, rewire the system or manufacture a new one. For example, every time you ask a large language model like ChatGPT or Claude a question, many electrical signals race through computer chips, carrying information and performing calculations. This takes energy, and lots of it. https://phys.org/news/2026-09-laser-temporarily-reprograms-ultrathin-optical.html Optics & Photonics Mon, 28 Sep 2026 13:00:13 EDT news709812601 When light or sound bounces around inside an oddly shaped room, its reflections can quickly become difficult to predict.

Without an atmosphere, a planet can't have surface water. But of the more than 6,300 exoplanets cataloged thus far, the vast majority are not rocky, and only a handful of the rocky worlds appear to have an atmosphere. https://phys.org/news/2026-09-coolest-lava-world-atmosphere-clues.html Astrobiology Thu, 24 Sep 2026 18:20:06 EDT news709469461 Honeycomb-shaped structures are familiar from beehives. Researchers have now designed molecules that self-assemble into a similar pattern on a scale far too small to see with the naked eye. These molecules are peptides: short chains of amino acids, the building blocks of proteins. Each peptide consists of only nine amino acids. Many identical copies assemble into tiny fibers with a honeycomb-like interior filled with water. https://phys.org/news/2026-09-short-peptides-honeycomb-fibers-tiny.html Bio & Medicine Thu, 24 Sep 2026 14:20:17 EDT news709474573 When the universe was still in its infancy—only 500 million years after the Big Bang, or about 3% of its current age—some of the universe's earliest stars and galaxies had already formed. Astronomers have long predicted that much of the gas surrounding these young galaxies must have remained relatively pristine, composed mostly of hydrogen and helium, the primordial ingredients available in the newborn cosmos. https://phys.org/news/2026-09-jwst-early-galaxies-seeding-universe.html Astrobiology Thu, 24 Sep 2026 05:00:04 EDT news709373161 If you want to understand the origins of black holes, Yale astronomers say, you need to look beyond the centers of galaxies and start searching in the nooks and crannies. That's where you'll find the "wanderers"—black holes whose journeys may tell the story of how the first black holes formed. https://phys.org/news/2026-09-roaming-black-holes-hidden-history.html Astronomy Wed, 23 Sep 2026 13:00:06 EDT news709380541 An international team of astronomers from ASTRON, JIVE, the University of Amsterdam and other institutions has found the first so-called "microblazar" in the Milky Way. This stellar system is composed of a massive star and a black hole with a jet that is pointed toward Earth. The researchers also identified the region where the jet hits a molecular cloud as a place where particles are accelerated to ultra-high energies, likely up to petaelectronvolts. This would make microblazars one of the most powerful particle accelerators in the galaxy. The research was appears in Astronomy & Astrophysics. https://phys.org/news/2026-09-milky-microblazar-fastest-particles-galaxy.html Astronomy Tue, 22 Sep 2026 11:40:01 EDT news709289641 The ubiquitous plastics of modern life are degrading into tiny fragments and littering Earth's landscapes and waterways. Scientists are starting to examine and measure this phenomenon to better understand how microplastics move through the environment and ultimately affect human and environmental health. A new study focuses on the Truckee River, which stems from the clear blue waters of Lake Tahoe and traverses Reno and Sparks, Nevada, before reaching Pyramid Lake. The research sought to illuminate the concentrations and types of plastics accumulating throughout the river—which supplies drinking water to nearly half a million people. https://phys.org/news/2026-09-truckee-river-microplastics-tenfold-high.html Environment Mon, 21 Sep 2026 15:30:02 EDT news709222321 For decades, Arctic sea ice has been melting earlier in spring and freezing later in fall, extending the melt season and contributing to widespread ice loss. A new NASA-led study published in Communications Earth & Environment has found that while the Arctic melt season has lengthened dramatically since satellite records began, that trend unexpectedly stabilized around 2010. https://phys.org/news/2026-09-satellite-reveals-arctic-season-plateaued.html Earth Sciences Mon, 21 Sep 2026 13:40:09 EDT news709212241 A star and its planets form when a cloud of gas and dust collapses in on itself somewhere in space. The cloud then forms a disk around the nascent star, within which the planets will form. This protostar and its disk then rotate in the same direction. https://phys.org/news/2026-09-rebellious-exoplanet-orbits-star.html Planetary Sciences Mon, 21 Sep 2026 11:00:01 EDT news709205883 Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced.

Silicon (Si) and silicon nitride (SiNx) are excellent photonic platforms for waveguides, but they cannot efficiently perform the ever-increasing tasks required for fully integrated optical systems. A heterogeneous photonic integration platform capable of interfacing different optical materials with high performance is thus an ongoing challenge for both academia and industry. https://phys.org/news/2026-09-photonic-legos-functional-3d-thin.html Optics & Photonics Mon, 21 Sep 2026 06:40:01 EDT news708945868 As we age, some of the cells in our body enter a state of senescence, in which they stop dividing but do not die. Those senescent cells can contribute to age-related disorders such as cancer, tissue degeneration and inflammatory diseases. In an advance that could lead to better ways to diagnose and treat those diseases, MIT researchers have developed a noninvasive way to detect biomarkers of senescence. Their method is based on Raman microscopy, which can reveal the biochemical composition of cells without harming them. https://phys.org/news/2026-09-ai-powered-barcode-unmasks-zombie.html Cell & Microbiology Mon, 21 Sep 2026 05:00:07 EDT news708944642 Researchers have developed a compact, handheld mid-infrared imaging spectrometer that can produce high-resolution chemical maps of a sample without using stains or labels.
