Time-lapse imaging reveals that the stem cells that generate sperm are located near blood vessels in the testis of mice, a different organization than in invertebrates.

At very high magnetic fields, charge transport in bismuth crystals behaves like a quantum fluid, an effect previously seen only in two-dimensional materials.

A chiral catalyst facilitates carbon bond formation across a large ring, yielding several edge-sharing smaller rings and offering efficient synthesis of complex polycyclic molecules.
