The mechanophore glows more intensely as the stretching increases.
To Buckle or Not to Buckle
Testing the stability of cylindrical tube made from 15,360 hexagonally packed magnetic balls (192 rings, each made up of 80 balls). A high-speed camera recording reveals crumpling at the base of the cylindrical tube, reminiscent of paper-like crumpling, when it loses stability from shaking.
Math Meets Art: Möbius Kaleidocycles
Dr. Johannes Schönke and Prof. Eliot Fried of the OIST Mathematics, Mechanics, and Materials Unit have introduced a new class of kaleidocycles into the world. They call them Möbius Kaleidocycles because they resemble the famous Möbius band, a geometrical object with a characteristic topology. These mystifying objects can be turned inside-out continuously and have unique mathematical properties. While classical kaleidocycles typically have six hinges, the new class of kaleidocycles can have seven or more. Not only are these objects beautiful to see, but they could also have very practical applications in a variety of fields.
Fluorescent Calcium Imaging
The neurons in this video contain a dye that fluoresces when it encounters calcium ions. When the neuron is excited, calcium floods into the cell and the neuron fluoresces. The researchers monitored experiments such as this one to see which neurons were firing synchronously and which were firing separately.
