MEMORY Maxed Out - with Nikolay Kukushkin!

What The If? ·

2025/09/26

What the if your brain literally ran out of storage space like a laptop refusing to save one more file? Neuroscientist Nikolay Kukushkin explains how memory isn't a filing cabinet but more like water carving rivers down a mountain - and when you carve too many paths, everything becomes a muddy mess. Discover why Mr. S, who remembered everything perfectly, couldn't recognize faces or taste food because his brain was too full of details. Learn why sleep is your brain's nightly cleanup crew and why

Science ROCKS On MARS!

What The If? ·

2025/09/12

What the if you found a rock on Mars that might - emphasis on might - show signs of ancient life? NASA's Perseverance rover discovered intriguing leopard spots in a 3.5-billion-year-old rock that contain vivianite, a mineral that could potentially indicate biological activity, though scientists remain cautiously skeptical. These dark-outlined splotches bear some resemblance to patterns that microbes can leave behind, but resemblance isn't proof. Join our trio as they explore the painstaking

VITALERIUM with Nicholas Casbarro!

What The If? ·

2025/09/05

Our guest this week is science fiction author Nicholas Casbarro, who brings us a universe-changing concept from his novel Vitalerium - a radioactive space rock that enables faster-than-light travel. What the if humans discovered this exotic material so powerful that a fist-sized chunk can propel a football field-sized spaceship at 12 times the speed of light? Matt helps us explore the real science behind faster-than-light travel, from grandfather paradoxes and causality violations to the vast scale

Apologies for the delay in posting episodes! Holiday and travel got the best of us. But we're back, baby! ---- WHAT THE IF we could trade genes like playing cards? Scientists have discovered that fungi possess "Starship elements" - massive genetic cassettes that jump between species carrying cargo genes for superpowers like heavy metal resistance. These DNA chunks got their Star Trek names because researchers kept seeing Vulcan hand signs in their data when one fungus had the element and another

The Case Of The MISSING Physics!

What The If? ·

2025/06/28

What the if we could go back to 1930 and experience the reluctant discovery of an entirely new kind of particle? When electrons started bouncing off things with missing momentum, physicist Wolfgang Pauli faced a choice: abandon the fundamental law of conservation of energy or invent something completely invisible to save physics. His solution was the neutrino - a particle so tiny and elusive it took 40 years to actually detect one, but so essential that billions are zipping through your body right
