Unfamiliar faces of the most unfamiliar substances: extraordinary activity of interfacial water on oil droplets
Raman-MCR spectroscopy of oil droplets in water. Credit: Nature (2025). doi:10.1038/s41586-025-08702-y Water behavior at hydrophobic interfaces has been baffling scientists for over a century, ranging from chemistry, biology, materials science, geology, and engineering. Recent discoveries highlight the pivotal role of interfacial water, including the unusual chemistry of water microdopplets and contact with electrocatalytics. A new study published in Nature systematically…

Natural substances derived from edible cyanobacteria may fight skin aging by strengthening collagen
Credit: ACS Agricultural Science and Technology (2024). DOI: 10.1021/acsagscitech.4c00571 Cyanobacteria, or blue-green algae, have existed for billions of years, adapting to diverse environments. Their remarkable ability to photosynthesize and make their own food and their adaptability to a variety of habitats have made them the focus of the research fraternity. One such cyanobacterium native to Japan, Aphanothece sacrum (also known…
