Astronomers have captured the central region of our Milky Way in a striking new image, unveiling a complex network of filaments of cosmic gas in unprecedented detail. Obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), this rich dataset — the largest ALMA image to date — will allow astronomers to probe the lives of stars in the most extreme region of our galaxy, next to the supermassive black hole at its centre.

Enzymatic biofuel cells can act as self-powered wearable biosensors by converting chemicals in body fluids into electricity; however, manufacturing challenges have prevented their widespread adoption. Now, researchers from Japan have developed water-based ‘enzyme inks’ that enable single-step screen printing of complete biofuel cells onto paper substrates. The printed electrodes demonstrated superior performance and stability compared to those made using conventional methods, paving the way for mass-produced, battery-free wearable health monitors.

Pyrochlore oxides are advanced dielectric materials that can potentially revolutionize energy storage capacitors. In a new review article, a group of scientists from Jeonbuk National University and the Korea Institute of Materials Science has summarized the latest developments in the field of pyrochlore ceramics and thin films, highlighting advantages, challenges, solutions, and next-generation applications. The present findings can guide the way for reliable, high-efficiency dielectric energy storage.

The Ateneo de Manila University Research on Optical and Electronic Systems (ROSES) Laboratory is the Philippines' first and only facility dedicated to locally designing Photonic Integrated Circuits (PICs) and training PIC designers.

Published in the Journal of Bioresources and Bioproducts, this study introduces a revolutionary mechanochemical strategy that challenges conventional material synthesis paradigms. The research demonstrates that water, when combined with mechanical grinding, can activate sodium methylsilicate to generate reactive hydroxyl groups, enabling condensation with over 40 different substrates ranging from natural macromolecules to metal compounds. The resulting hydrophobic porous materials exhibit exceptional properties including surface areas of 129–388 m²/g, yields of 66%–90%, and remarkable versatility in environmental applications. Notably, the system can directly utilize untreated plant tissues and atmospheric CO₂, converting the greenhouse gas into valuable sodium bicarbonate byproducts. The materials demonstrate outstanding performance in oil-water separation with petroleum ether permeability exceeding 801 L/(m²·h), propofol medical waste adsorption rates above 85%, and dye degradation efficiencies reaching 99.99% for pollutants including Rhodamine B, Congo red, and Nile red. This work establishes a generalizable platform for sustainable material manufacturing that aligns with green chemistry principles, requiring no heating, organic solvents, or harmful catalysts while maximizing the utilization of naturally abundant renewable resources.

Gold nanoparticles with surface functionalization are vital to improve their stability, bio-compatibility to engineer them to be suitable candidates in advanced bio-medical technologies, including drug delivery systems, biosensors, bioimaging, photothermal cancer therapy etc.  They are also being exploited in catalysis and energy applications. Their performance in these applications depends strongly on how their surfaces interact with the surrounding medium, particularly the interfacial water, at the nanoscale. Therefore, understanding the thermodynamics and intermolecular structure of the interfacial water is crucial in the design process.

Contamination of ground, surface and drinking water by perfluoroalkyl and polyfluoroalkyl substances (PFAS) affects millions of people worldwide.

A promising new method developed by Flinders University scientists paves the way to help remove the most difficult-to-capture variants of these persistent pollutants from water.

Excess phosphorus in lakes and reservoirs fuels harmful algal blooms, threatens drinking water safety, and damages aquatic ecosystems worldwide. Now, researchers have developed a new machine learning–guided strategy to design advanced biochar materials that remove phosphorus efficiently while dramatically lowering treatment costs. The study provides a practical pathway for restoring eutrophic waters at large scale.

Researchers have developed a new biochar material derived from marine microalgae that can detect hydrogen peroxide rapidly, sensitively, and without the need for enzymes. The discovery could support applications ranging from medical diagnostics to environmental monitoring and food safety.
