Friday Jan 31, 2025
Friday Jan 31, 2025
This week on Break It Down: A CIA report says the origins of COVID being a lab leak is “likely” but what does that really mean? The Doomsday Clock ticks closer to humanity's destruction, asteroid Bennu’s sample contains the building blocks of life (but not aliens), the oldest poison arrow dates back 7,000 years, a mouse with two male parents survives to adulthood in a world first, “boomerasking” might be the social snub of 2025, and we enter The Vault to explore why people believe in the Simulation Hypothesis.
So sit back, relax, and let’s Break It Down…
