High Fidelity
Theoretical cellular physicists Jian Liu and his postdoctoral fellow Jing Chen developed a new model for how the subcellular spindle apparatus prevents cells from reproducing with the wrong number of chromosomes. They introduce the potentially game-changing proposition that the spindle structure itself is critical for ensuring accurate cellular reproduction. Read more.
