💻 Technology

🇺🇸 🇮🇸 US and Icelandic scientists turn fiber-optic cables into volcano early-warning system with 30-minute alerts

In a major international collaboration, researchers from Caltech and Iceland used distributed acoustic sensing (DAS) to convert a 62-mile underground fiber-optic cable into a real-time volcanic monitoring system. This innovative setup on Iceland’s Reykjanes Peninsula detects magma movement with millimeter precision, enabling warnings up to 30 minutes before eruptions. The system, which was successfully tested during 2024 eruptions, offers a transformative tool for disaster preparedness in volcanic regions. Published in Science.

⚡️ Energy

🇨🇭 Swiss engineers launch world’s first removable solar array on live railway, aiming for energy self-sufficient trains

Swiss startup Sun-Ways has activated a 48-panel, 18 kW track-mounted solar installation on an active railway in Buttes, marking the world’s first removable solar plant integrated with operational rail lines. Expected to generate 16 MWh annually, the system feeds electricity to the public grid and is designed for rapid deployment using a specialized train. The innovation could pave the way for nearly self-powered trains and scalable solar adoption across rail networks.

🌎 Sustainability

🇺🇸 US researchers create first scalable fiber-to-fiber textile recycling to turn old clothes into high-quality fabric

Scientists at the University of Nebraska–Lincoln have developed a water-based recycling method that removes dyes, separates fiber blends, and transforms old garments—like denim—into high-quality new fibers. Unlike existing methods that downcycle textiles, this process preserves fiber integrity and recycles solvents, offering a truly circular solution for cotton, synthetics, and blends. Published in Resources, Conservation and Recycling, the breakthrough could reshape textile sustainability if scaled industrially.

💉 Biotechnology

🇬🇧 UK scientists enhance Himalayan fungus compound for 40x stronger anti-cancer drug now in Phase 2 trials

Researchers from the University of Oxford and biopharmaceutical company NuCana modified the natural compound Cordycepin, derived from a Himalayan fungus, to create NUC-7738, a chemotherapy drug up to 40 times more potent against tumors. By chemically shielding the molecule from breakdown and easing its entry into cancer cells, they overcame key resistance barriers, showing strong early clinical results with limited toxicity. Published in Clinical Cancer Research.

💊 Healthcare

🇺🇸 US biotech advances reversible male birth control injection to Phase 2, lasting up to 2 years

American company Contraline has gained approval to begin Phase 2 human trials in Australia for ADAM™, a reversible male contraceptive injectable that blocks sperm in the vas deferens for up to two years. Early results show a near-total reduction in motile sperm with no serious side effects, and two participants have reached complete sperm suppression after 24 months. This hydrogel-based implant could become the first long-lasting, non-hormonal male contraceptive.

🇩🇰 Danish scientists create 'super stem cells' by sugar switch, boosting IVF and anti-aging therapies

Danish researchers at the University of Copenhagen have discovered that replacing glucose with galactose in embryonic stem cell cultures forces cells to use a different energy pathway, dramatically improving their health and ability to form specialized tissues. These “super stem cells” not only remain youthful and resilient longer but also show superior performance in forming key embryonic structures important for IVF implantation. The technique could enhance fertility treatments and offer new strategies for tackling degenerative diseases and aging-related conditions. Published in EMBO Reports.
