Webb captures Neptune’s auroras for first time
Mar 26, 2025 Neptune was the missing piece of the puzzle when it came to detecting auroras on the giant planets of our solar system. (Nanowerk News) For the first time, NASA’s James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles, often originating...
Webb sees galaxy mysteriously clearing fog of early universe
Mar 26, 2025 Astronomers discovered bright hydrogen emissions from an ancient galaxy, puzzling researchers over how this light pierced the universe's early hydrogen fog. (Nanowerk News) Using the unique infrared sensitivity of NASA’s James Webb Space Telescope, researchers can examine ancient galaxies to probe secrets of the early universe. Now,...
Nanomedicine with siRNA shows first effectiveness against the human-pathogenic fungus Aspergillus fumigatus
Mar 26, 2025 The study demonstrates that this RNAi approach shuts down vital fungal genes, thereby inhibiting pathogen growth - a groundbreaking step in the development of new antifungal therapies. (Nanowerk News) Fungal infections are on the rise globally. According to a study by the Manchester Fungal Infection Group, in...
Sensor technology uses nature’s blueprint and machinery to monitor metabolism in body
Mar 26, 2025 Researchers developed an advanced sensor platform that measures metabolites - key molecules involved in sustaining life through metabolism - inside the body in real time. (Nanowerk News) Life’s essential functions are powered by a set of compounds called metabolites, which are involved in every natural process including...
New light-induced polymer material formation method to improve 3D printing resolution
Mar 26, 2025 Scientists developed a new photopolymerisation reaction controlled antagonistically by two different colours of light. Specifically, one light beam promotes the formation of the polymeric material, while another beam halts the reaction. (Nanowerk News) At present, 3D printing is an increasingly widespread and accessible technology, typically involving the...
Bacterial nanocellulose stents offer precise drug delivery and improved biocompatibility
Mar 26, 2025 (Nanowerk Spotlight) Millions of medical procedures every year rely on stents—small mesh-like tubes—to keep body channels open when diseases threaten to close them off. These stents help restore blood flow, keep airways open, and maintain the function of passages in the digestive and urinary systems. Yet, existing...
These electronics-free robots can walk right off the 3D-printer (w/video)
Mar 26, 2025 A fully 3D-printed walking robot made from a single material and powered by compressed gas works without electronics or external control systems. (Nanowerk News) Imagine a robot that can walk, without electronics, and only with the addition of a cartridge of compressed gas, right off the 3D-printer....
Discovery of chemical oscillations in palladium nanoparticles paves the way for recycling precious metal catalysts
Mar 26, 2025 Scientists have for the first time filmed the real-time growth and contraction of Palladium nanoparticles, opening new avenues for utilising and recycling precious metal catalysts. (Nanowerk News) Scientists have for the first time filmed the real-time growth and contraction of Palladium nanoparticles, opening new avenues for utilising...
Cleverly designed carbon nanohoop enables controlled release of iron
Mar 26, 2025 Researchers integrated ferrocene (Fe-containing molecular sandwich) with carbon nanohoops to create a system releasing Fe2+ ions when activated by green light. (Nanowerk News) In an international cooperation, researchers at the Universities of Amsterdam and Zurich have developed a molecular system for controlled release of iron. They integrated...
