Sean Carroll | Wondery

Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

A journey through the mechanisms of muscles and muscular contraction. I begin by outlining the key structural elements of muscle cells, including the sarcolemma, sarcoplasmic reticulum, the myofibrils and their myofilaments. I then explain the sliding filament mechanism of muscle contraction, and how it is governed by neural signals through the release of calcium. I conclude with a brief overview of the types of muscle contractions, the difference between fast twitch and slow twitch muscle fibres, and a short discussion of some metabolic aspects of muscle function, including the role of creatine phosphate. Recommended pre-listening is Episode 26: Human Organ Systems.
