Why do your knuckles pop? - Eleanor Nelsen. Want to learn the latest on this topic?
Read the recent publication: Real Time Visualization of Joint Cavitation aka “knuckle cracking!” Then listen to the latest Morning Edition at NPR: Why Knuckles Crack! Scroll down at the site and watch an MRI of knuckle cracking in real time to see the “pop” during the “pull my finger study!” Here’s another interesting physiological phenomenon that has to do with gas solubility: decompression sickness, or “the bends.” When divers are deep underwater, they experience ambient pressure much higher than it is on land.

Angela Lee Duckworth: The key to success? Grit. These Are The Things That Make Up A Successful Person And An Unsuccessful Person. 18 Things Highly Creative People Do Differently. This list has been expanded into the new book, “Wired to Create: Unravelling the Mysteries of the Creative Mind,” by Carolyn Gregoire and Scott Barry Kaufman.
Creativity works in mysterious and often paradoxical ways. Creative thinking is a stable, defining characteristic in some personalities, but it may also change based on situation and context. Inspiration and ideas often arise seemingly out of nowhere and then fail to show up when we most need them, and creative thinking requires complex cognition yet is completely distinct from the thinking process.
Neuroscience paints a complicated picture of creativity. As scientists now understand it, creativity is far more complex than the right-left brain distinction would have us think (the theory being that left brain = rational and analytical, right brain = creative and emotional).

Watch this bead chain loop defy gravity and bend physics. Science is unendingly cool because it can consistently confound the expectations of researcher and layman alike.
Case in point, what do you figure would happen if you had a bead chain coiled up in a small container, then pulled one end out? You probably didn’t guess that it would leap up and uncoil like a tiny metallic snake, but that’s what happens. This demonstration is sometimes called Newton’s Beads. It’s an unexpected trick of physics, but the mechanics behind it are fairly simple.
