High diving puts the human body through forces most people never experience outside of a car crash. The deceleration on water entry at extreme heights can exceed 50 G's, and the difference between a clean entry and a catastrophic injury comes down to body alignment in the final milliseconds before impact. Divers train obsessively to enter water with their body rigid and perfectly vertical because that position distributes the impact force evenly across the skeleton. Any deviation concentrates th

A new IV needle design is solving a problem that's existed since the IV was invented. Traditional needles are rigid for the entire duration they're placed in a vein, and since your body is constantly moving, that rigidity causes friction and irritation against the vessel wall over time — especially during long-term treatments. This new flexible needle is engineered to remain stiff only during insertion, then soften once it reaches body temperature inside the vein. That shift allows the needle to
