Ivar Giaever, a pioneering physicist who won the Nobel Prize for his groundbreaking work in quantum tunneling—a discovery that revolutionized electronics and superconductivity—has passed away at 96. His research laid the foundation for modern technologies like MRI machines and quantum computing. Giaever was known for his sharp wit and later controversial climate skepticism, but his scientific legacy remains towering.

Franklin W. Stahl, a pioneering molecular biologist who passed away at 95, co-designed a groundbreaking experiment that confirmed how DNA replicates—a key piece of the puzzle in understanding life's blueprint. His elegant work, praised as "beautiful," validated the theories of Watson and Crick, the duo who first uncovered DNA's double-helix structure.
