A journey through the history of Earth's changing climate, in which we explore how Earth's climate has fluctuated over the past billion years. After reviewing the various temperature proxies used to estimate past climactic conditions, we discuss the varying hothouse and icehouse periods of Earth's history, the onset of the Quarternay Ice Age, the current interglacial period, the anomoly of the Younger Dryas, the Medieval Warm Period and Little Ice Ages, and the rapid rise in temperatures during the twentieth century. Recommended pre-listening is Episode 90: Climate Systems.

In this special collaboration with I Know Dino podcast, we discuss the history and impact of dinosaurs in popular culture and media. We cover the history of the scientific study of dinosaurs and how their presentation in media has changed over time with new discoveries, and what aspects of their behaviour and appearance tend to be presented accuracy or inaccurately. We also discuss lesser-known aspects of understanding dinosaurs, such as how changes in the atmosphere and ecosystem would affect dinosaurs of they were to be alive today.

Episode 133: Motor Control

Episode 133: Motor Control

2023-01-0101:17:011

A journey through the complex network of regions controlling the human motor system, beginning with the spinal cord and its central pattern generators, and working up through the primary motor cortex, the premotor cortex, the posterior parietal cortex, the cerebellum, and the basal ganglia. I discuss the computational roles of each part of the motor control hierarchy, focusing on what functions are performed and what information is represented in each unique brain region. Overall I emphasise the complex interaction between top-down and bottom-up feedback in controlling muscle movement and executing complex motor tasks. Recommended pre-listening is Episode 132: The Muscular System, and Episode 38: Neurons and Synapses.   If you enjoyed the podcast please consider supporting the show by making a PayPal donation or becoming a Patreon supporter. https://www.patreon.com/jamesfodor https://www.paypal.me/ScienceofEverything
In this special episode I discuss various topics in evolution and genetics with Art Woods of the Big Biology Podcast. We begin by analysing various ideas associated with the extended evolutionary synthesis, including plasticity, epigentics, and niche construction, discussing the extent to which these ideas are a challenge or merely an addition to the mainstream understanding of evolution. We then consider several common misconceptions about genetics, including the idea of DNA as a blueprint and genetic essentialism. We conclude with a discussion of some politically contentious aspects of genetics.   If you enjoyed the podcast please consider supporting the show by making a PayPal donation or becoming a Patreon supporter. https://www.patreon.com/jamesfodor https://www.paypal.me/ScienceofEverything
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.

nice cover photo for podcast, NOW, if alehed scientists of Carl Sagan era could have ONLY put this photo on Voyager space craft before send off to universe to advertise humans, this picture alone, is more valuable than 33 1/3 gold record recording, and other limited ideas that would be civilizations have to dcode without ANY prior knowledge, so, this podcast slbum cover photo alone id far more inteligent and says more about humans on earth ... and the podcast medical topics are great (or very very good!) one should collect them all aka mp3 download and put into your permanent atchive of smart things to collect ... thank you everyone involved!

you said to tell you if we're listening, and I thought of course I am, and noticed my state and it amused me! so, I'm cutting up an old cotton t-shirt to make into sustainable makeup wipes and pads at 3 am and thinkingabout startinga low waste life YouTub channel, I'm a 24 yr old girl in tehran, October 2022, just fell in love, in the middle of an uprising for women, life, freedom, have a work meeting in a few hours, before this I was listening to Rumi, and I actually played "energy, work, momentum " thinking it was a career and hustle thingy and was delighted to see it was a physics and life thingy and returned me to my lost love! so yeah, I'm listening to you, you're talking to me about physics and it's lovely :)
