[BONUS] How the moon causes tides and ancient viruses lurking in your DNA: Tiny Show and Tell Us #7

Sep 25, 2024
Join science communicator George Zaidan as he unpacks the fascinating science of tides, explaining why some regions experience extreme tidal swings while others don’t. He vividly illustrates the moon’s gravitational pull creating two daily tides. Shift gears as George and Sam delve into ancient viral DNA in the human genome, revealing its surprising connection to cancer treatment resistance. They discuss how endogenous retroviruses could potentially hinder therapy effectiveness and explore new ways to enhance cancer treatments.

ANECDOTE

Georgia Bight Produces Huge King Tides

  • Will wrote that coastal Georgia sees tidal swings exceeding 10 feet during king tides due to the Georgia Bight.
  • The continental shelf shape and inward flow of wave energy concentrate tides on the Georgia coast.
INSIGHT

How The Moon Creates Two Daily Tides

  • The moon's gravity pulls on every point of Earth differently, creating two ocean bulges and two low points each day.
  • The solid Earth moves differently from the oceans, so one bulge forms toward the moon and another forms on the far side.

Sun, Geography And Resonance Shape Tides

  • Tidal patterns get more complex when the sun's gravity overlaps with the moon's tidal forces.
  • Coastal geography and bay shapes can amplify tides, producing extreme swings like king tides.
