ATLAS’s wheel-like end-cap reveals the maze of sensors primed to catch proton smash-ups at the LHC. Researchers comb through billions of events in search of fleeting “ghost” tracks that might expose cracks in string theory.

A collaborative team from the School of Engineering and Applied Science and the Perelman School of Medicine have unraveled the mathematics of a 500-million-year-old protein network that acts like the body’s bouncer, “deciding” which foreign materials get degraded by immune cells and which are allowed entry.

In eusocial superorganisms like leafcutter ant colonies, labor is divvied up according to body shape and size, but PIK Professor Shelley Berger and her team discovered that molecular signals can override that blueprint. Their findings reveal how simple neuropeptides can reprogram ant behavior, reshuffling roles in nature’s most disciplined workforce.
