We're kicking off our exploration of muscles with a look at the complex and important relationship between actin and myosin. Your smooth, cardiac, and skeletal muscles create movement by contracting and releasing in a process called the sliding filament model. Your skeletal muscles are constructed like a rope made of bundles of protein fibers, and that the smallest strands are your actin and myosin myofilaments. Its their use of calcium and ATP that causes the binding and unbinding that makes sarcomeres contract and relax.

Is it possible to reconstruct sound from high-speed video images?
Part of this video was sponsored by LastPass: http://bit.ly/2SmRQkk
Special thanks to Dr. Abe Davis for revisiting his research with me: http://abedavis.com

This video was based on research by Dr. Abe Davis and colleagues. I found out about this work years ago and was fascinated by the way he was able to capture vibration information in image-only video. I always imagined the motions of objects would be visible as when recording a tuning fork in slow motion - so deriving sound from high speed images seemed a feasible task. But the reality is much more difficult.

Sound vibrations only cause objects to wiggle by about a micrometer. This is much smaller than a pixel, so the algorithm must understand the characteristics of the image. A move in one direction should cause some pixels to lighten slightly, while others darken - and this behavior is correlated along the edges of the image. So noise can be reduced because it's random over the image and there are enough places to sample that you can get it to cancel out.

Something I'm wondering now is - would it be possible to capture sound in a single image? I'm thinking it would have to be an image of a large object or space because the wavelengths of typical sounds are quite long. Maybe a high frequency sound could be imaged in a suitable medium...

Boeing’s Starliner spacecraft launched aboard an Atlas V rocket on an Orbital Flight Test at 6:36 a.m. EST, Friday, Dec. 20, 2019. The spacecraft had an off-nominal orbit insertion, but was placed in a safe orbit and configuration and landed at White Sands, New Mexico on Dec. 22.

Plants may be stationary but they're rarely still, says biologist Roger Hangarter, creator of the website Plants in Motion. Researchers are using time-lapse photography to study the biomechanics of plant movement. For example, this week in the journal Science, physicist Sharon Gerbode, of Harvey Mudd College, and biologist Joshua Puzey, of Harvard University, explain how they used time-lapse, mathematical modelling and a prosthetic plant to understand how cucumber tendrils twist.
