Laboratory of Molecular Biology after their formal retirement including: Max Perutz, following an undergraduate training in organic chemistry, left Austria in 1936 and came to the University of Cambridge to study for a PhD, joining the X-ray crystallographic group led by J.D. Bernal. Here, in the Cavendish laboratory, he started his lifelong work on hemoglobin. The death of Lord Rutherford led to his successor, Lawrence Bragg, a pioneer in X-ray crystallography, becoming the new Cavendish professor of physics in 1938. Bragg became a major supporter of Perutz and his group in those early days. After World War II, many scientists from the physical side
Applied Physics Laboratory was used in 2016 for a demonstration in which a paralyzed man was able to "fist-bump" Barack Obama using signals sent from an implanted brain chip. The limb returned sensory feedback from the arm to the wearer's brain. The APL researches and produces unmanned aerial vehicles for the US military. One of its most recent projects is an unmanned aerial swarm that can be controlled by a single operator on the ground.
