Inverted Assembly of the Lens Within Ocular Organoids Reveals Alternate Paths to Ocular Morphogenesis

This important study demonstrates that ocular organoids can generate both retina and lens through a non-canonical, "inside-out" morphogenetic route. The work is solid, with well-designed experiments ...

A new approach to magnify wave functions when imaging interacting ultracold atoms

The precise imaging of many-body systems, which are comprised of many interacting particles, can help to validate theoretical ...

Spin may resolve century-old puzzle of light's momentum in matter

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, ...
