Five Berkeley scholars — four faculty members and one research scientist — have been elected fellows of the American Association for the Advancement of Science (AAAS), one of the world’s largest scientific societies. The distinction was awarded this year to 489 scientists, engineers and innovators for their advancement of science and its applications.
Off the Scales: Fish Armor Both Tough and Flexible
Humans have drawn technological inspiration from fish scales going back to ancient times: Romans, Egyptians, and other civilizations would dress their warriors in scale armor, providing both protection and mobility. Now, using advanced X-ray imaging techniques, scientists have characterized carp scales down to the nanoscale, enabling them to understand how the material is resistant to …
UC Berkeley Professor Robert Ritchie Co-Leads Study on Fish Scales Which May Provide Better Armor
A project led by Robert Ritchie, professor of mechanical engineering and materials science at UC Berkeley, and Marc Meyers, professor of nanoengineering at UC San Diego, provides inspiration for fish scales to be used in armor.
Piranha-Proof Fish Scales Offer Inspiration for Better Armor
Arapaima gigas. Image by iStock.com/kurga The scales of the massive Amazonian freshwater fish, Arapaima gigas, are so tough that they do not tear or crack when a piranha—which has one of the animal kingdom’s sharpest bites—attacks. Material scientists have discovered the secret to the fish’s impermeable armor: each scale is made up of a highly …
