A wall-climbing robot uses the zero-pressure difference method to form suction. Credit: Xin Li and Kaige Shi Centrifugal force from a high-speed rotating water ring enables gripping rough surfaces. Specially designed vacuum suction units allow humans to climb walls. Scientists have developed a suction unit th...-

The anchor spicules that hold the sponge species Euplectella aspergillum to the ocean floor have an intricately layered internal structure. Similar layered structures are known to increase the toughness of materials like bone and nacre. But this new research finds that the layering in the spicules does little...-
