During World War II, engineers studied planes that returned from missions. They first thought the areas with the most bullet holes needed armor. Statistician Abraham Wald realized this was survivorship bias. Survivorship bias happens when you focus only on survivors and ignore failures.The undamaged areas on returning planes were actually the critical spots. Planes hit there did not survive. He recommended reinforcing those undamaged areas.

Both Gummy candies and cars are coated with carnauba wax. In candies, it gives a shiny surface and stops them from sticking together. In cars, it protects paint, repels water, and gives a glossy finish. Carnauba wax comes from palm leaves in Brazil. It is very hard, has a high melting point, and is safe to eat. This natural wax works well in both food and automotive uses because it is durable, glossy, and heat-resistant. Sadly it does not keep cars from sticking together😉.

Phagocytosis is the brain eating itself.

The working of the brain creates a kind of debris that has to be removed, otherwise it builds up and disrupts things. Most of this eating happens when we sleep, that’s one theory to why we even need sleep.

Brazil’s Amazon is home to over 100 uncontacted Indigenous groups who, after traumatic encounters with outsiders and the memory of enslavement, choose isolation to protect themselves; they often hide deep in the forest or actively resist contact—shooting arrows at intruders or planes—to defend their territory and health.

“Hector the Convector” is a giant thunderstorm that forms over Australia’s Tiwi Islands at around 3 p.m. local time, most often between September and December. No other thunderstorm system is known to match its combination of repeated location and daily timing during this season. Sea breezes collide over the islands and push warm, moist air upward, creating the storm. WWII pilots reportedly used the cloud as a navigation landmark. The storm can grow up to 20 km high and can be seen from Darwin, about 100 km away.

Locusts are certain grasshopper species that can switch between two forms, unlike most grasshoppers.

When crowded, repeated touch triggers serotonin changes. They shift from a solitary phase (green, avoiding others) to a gregarious swarm phase.

In swarm form, they develop a more compact, stronger body, longer wings, stronger flight muscles, and yellow, black, and orange colors, and move in large groups. When populations drop and they become more isolated again, they can shift back toward the solitary form over time.
