    The Pneumonic Plague

    The Black Death is famous, but the plague has a deadlier form, and it doesn’t need fleas to spread. Pneumonic plague infects the lungs and passes from person to person through the air, and without fast treatment it is almost always fatal. In this episode of Knowledge Central, we look at how the same bacterium behind history’s worst pandemics turns into a respiratory killer, the outbreaks that showed the world how dangerous it is, and why it still hasn’t completely gone away. In this episode: The bacterium Yersinia pestis, and how pneumonic plague differs from bubonic plagueWhy spreading through the air makes this form so dangerousThe 1910–11 Manchurian plague, and the doctor whose masks helped stop itHow modern antibiotics turned a near-certain death sentence into a treatable disease, if it’s caught earlyWhere plague still appears today, including recent outbreaks in MadagascarWatch the video version on YouTube at Knowledge Central.  🧠 Subscribe: https://www.youtube.com/@knowledgecentralnetwork?sub_confirmation=1 Enjoyed this episode?

    The Kelvin Wave. Why Your Weather Changes

    Some of the most powerful waves on Earth are almost invisible. Kelvin waves are giant, slow-moving waves that travel thousands of miles across the ocean, raising the sea surface by only a few inches while shifting warm water deep below. In this episode of Knowledge Central, we explore how Kelvin waves work, why the equator traps them, and how they help set off El Niño, which can change weather around the entire planet. In this episode: What a Kelvin wave is, and who Lord Kelvin wasHow Earth’s rotation keeps these waves locked to the equator and to coastlinesWhy a wave that’s only inches high at the surface can move huge amounts of warm waterHow Kelvin waves cross the Pacific in a couple of months and help trigger El NiñoWhat El Niño means for droughts, floods and weather far from the oceanWatch the video version on YouTube at Knowledge Central.  🧠 Subscribe: https://www.youtube.com/@knowledgecentralnetwork?sub_confirmation=1 Enjoyed this episode?
