Podcasts about protist

This conversation will make you want to buy a microscope and will make you rethink the way you envision the Tree of Life, where animals, plants and fungi are just a tiny speck on the overall tree of life.Dr. Julia Van Etten (of the @Couch Microscopy Instagram page) talks about what the hell a Protist is and where you can find them (everywhere). We reveal how Protists are the fine particles that weave within and throughout our world."The Tree of Life is Really a Web".

Po komunistickém převratu v únoru 1948 se jednou z klíčových institucí stala Státní bezpečnost. Jejím hlavním posláním bylo hledat a likvidovat nepřátele nového režimu – skutečné i domnělé. Najednou tak proti sobě nestáli Češi a Němci, ale soused proti sousedovi. Ale doopravdy zjistit, kdo je nepřítel, bylo téměř nemožné. A ti, kdo se ocitli „v sítích“, neměli žádnou šanci – čekala je smrt nebo dlouhá věznění.Všechny díly podcastu Jak to bylo doopravdy můžete pohodlně poslouchat v mobilní aplikaci mujRozhlas pro Android a iOS nebo na webu mujRozhlas.cz.

People are pretty well-versed in charismatic megafauna–lions and tigers and bears (and others) oh my! But have you thought about protists recently? We didn't think so. These single-celled organisms, though tiny, are essential to life on Earth. Find out more about their characteristics, purpose, and why they're so important in today's episode!Support the show

This episode: A bacterial communication signal makes algae stop growing, which helps them survive virus attacks! Download Episode (5.3 MB, 7.7 minutes) Show notes: Microbe of the episode: Veillonella parvula   Takeaways Many interesting interactions between microbes take place in the ocean. As single-celled organisms lacking complex sensory organs, many such interactions and communications are mediated by chemical signals. Some bacteria, for example, each produce small amounts of certain chemicals and release them into the environment. When the concentration of the chemical signal builds up to a certain point, the bacteria change their behavior to take advantage of their high numbers that must be present to produce so much of the signal. This process is called quorum sensing.   Some of these chemical signals can affect the behavior of organisms other than bacteria also. In this study, a common marine algal species was found to stop growing in response to a certain bacterial signal. This chemical inhibits an enzyme required for the algae to produce nucleotides to replicate their genomes. As a result, the algae are able to resist destruction by a virus that would otherwise decimate their populations.   Journal Paper: Pollara SB, Becker JW, Nunn BL, Boiteau R, Repeta D, Mudge MC, Downing G, Chase D, Harvey EL, Whalen KE. 2021.

This episode: Single-celled eukaryotes can thrive without oxygen with the help of bacterial endosymbionts that respire nitrate the way our mitochondria respire oxygen!   Thanks to Jon Graf for his contribution! Download Episode (12.4 MB, 18.1 minutes) Show notes: Microbe of the episode: Brenneria salicis   News item 1 / News item 2   Takeaways The combination of a bacterium and other microbe into the first eukaryote was a big advance in evolutionary history; it made possible the huge variety of different body shapes and sizes we see today. This is thanks to the bacterial endosymbiont, the mitochondrion, taking on specialized metabolic tasks for the cell.   We already knew about endosymbionts that help with oxygen respiration, with photosynthesis (chloroplasts), and with amino acid synthesis (certain endosymbionts in insects). But bacteria have other metabolic abilities that are very useful in certain conditions; do these bacteria ever team up with other organisms? The answer is yes! In this study, ciliates were discovered at the bottom of a lake in oxygen-free waters. These protists have an bacterial endosymbiont that helps them respire, not oxygen, but nitrate instead, generating more energy than most anaerobic ciliates.   Journal Paper: Graf JS, Schorn S, Kitzinger K, Ahmerkamp S, Woehle C, Huettel B, Schubert CJ, Kuypers MMM, Milucka J. 2021.

This week’s episode Luna will delve into the realm of a blob that might hold secrets about our own intelligence - it can make up complete railway networks, solve mazes and even “mind”-control a robot. The name of the blob? Slime mould. A yellow gooey creature that scavenges the environment by stretching and pulsating its gigantic unicellular body - do not be fooled by its name, this fellow is neither a mould, nor a fungi - but something called a Protist!

Met het blote oog kun je ze niet zien en begrijpen doen we ze eigenlijk ook niet. Dinoflagellaten - ook wel liefkozend dinootjes genoemd - zijn plankton met bijna buitenaardse krachten. Ze bezitten het sterkste gif dat we kennen, geven betoverende lichtshows en vormen een geschiedenisboek van het klimaat. En dus vroegen we hun grootste fan om aan te schuiven: Ellen de Bruin, die er een roman over schreef.Presentatie: Lucas Brouwers en Gemma VenhuizenProductie: Mirjam van Zuidam@lucasbrouwers // @GemmaJV // @ellendebruinBenieuwd hoe deze dinootjes er uitzien?

This episode involves a Nature Walk contest, "Who's That Non-Bird: Killer Edition". (We'll save the killer birds for another day.) The contest question is this: which non-birds are responsible for the most human deaths in the world per year? Warren asks the rest of us to guess the top 11. Here's a little foreshadowing: Warren will cite some stats for non-animal causes of death for contrast, and John will contest them furiously. This contest is only one episode, but it's still surprisingly long, or at least it feels that way... If you want to correct any of Warren's statistics, send us an email (maskedman@limitedappeal.net).
