In a technique called micropipette aspiration, a hollow needle (micropipette) is used to suck up (aspirate) layers of the nucleolus, a structure within the nucleus of a frog egg cell. The outer layer, or granular component (magenta), is liquid-like, while the dense fibrillar component (green) behaves more like a solid. Graphic by Neil Adelantar; video by Holly Cheng

Lines of code written in C on a black background
Much of the code ever written is in the C programming language, but C has a major security vulnerability that can result in serious bugs, like the one pictured here. Now, Princeton computer scientists have created a tool that protects updated systems written in safer languages during interactions with C code.
