Two separate biology studies have been published across the Science journal family.

One study, appearing in Science, mapped brain-wide activity patterns that trigger emotions in humans and mice.[^1]

A second study was published 11 September 2026 in Science Advances, describing a human bone marrow-on-a-chip model.[^2]

The bone marrow-on-a-chip platform combines a lymph node organoid with a microfluidic bone marrow mimic to observe plasma cell development.[^3]
