Math Meets Art: Möbius Kaleidocycles
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.
The mechanophore glows more intensely as the stretching increases.
The polymer material is stretched with an increasing force resulting in a corresponding brighter emission of light from the mechanophore (here under UV light and with false colors). The graph shows the intensity of the emitted light following punctual increases in the stretching force applied to the polymer.
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.
