Novel nanostructures in blue sharks reveal their remarkable potential for dynamic color-change

New research into the anatomy of blue sharks (Prionace glauca) reveals a unique nanostructure in their skin that produces their iconic blue coloration, but intriguingly, also suggests a potential capacity for color change. The research was presented at the Society for Experimental Biology Annual Conference in Antwerp, Belgium on July 9, 2025. "Blue is one of the rarest colors in the animal kingdom, and animals have developed a variety of unique strategies through evolution to produce it, making these processes especially fascinating," says Dr. Viktoriia Kamska, a post-doctoral researcher in the lab of Professor Mason Dean at City University of Hong Kong. The team revealed that the secret to the shark's color lies in the pulp cavities of the tooth-like scales—known as dermal denticles— that armor the shark's skin.

some nanostructures notes 🔬

i had an exam yesterday and prepared well for it with a summary of the book chapter.. but i only had time to read half of it. i still think i’ll do ok though. i hope.

Search for new semiconductors heats up with gallium oxide

University of Illinois electrical engineers have cleared another hurdle in high-power semiconductor fabrication by adding the field's hottest material - beta-ga

Flat transistors have become about as small as is physically possible, but researchers addressed this problem by going vertical. With a technique called metal-assisted chemical etching - or MacEtch - U. of I. engineers used a chemical solution to etch semiconductor into 3D fin structures. The fins increase the surface area on a chip, allowing for more transistors or current, and can therefore handle more power while keeping the chip's footprint the same size.
