    Probiotika i munden: Hype eller hjælp?

    Probiotika skal ifølge reklamerne skabe balance i kroppens bakterier - men virker det i munden? Christine Lundtorp gennemgår forskningen i probiotika som forebyggelse og behandling af mundsygdomme, og skelner marketing fra dokumenteret effekt. Gæst: Christine Lundtorp, forsker, tandlæge, Københavns Universitet

    From Wobbles to Worlds - Discovery of The Exoplanet Edge!

    Thanks to Incogni for sponsoring us. Use the code coolworlds at https://incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan. Today we explore what could be considered a classic problem in exoplanetary science, yet one which has eluded astronomers for decades. Transit timing variations (TTVs) are seen in thousands in systems, literally wobbling worlds. Yet for the vast majority of cases, we have no solution for the culprit. Today, we present new research from our team that finds analytic expressions for the allowed solution space and reveals the startling existence of an "exoplanet edge". Written & presented by Prof. David Kipping & Daniel Yahalomi. Edited by Jorge Casas & David Kipping.
