Cells

As it becomes clear that the body’s cells have more diverse regenerative capabilities than expected, experts have had to reconsider their approach to stem cell research.

With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.

The physicist Lisa Manning studies the dynamics of glassy materials to understand embryonic development and disease.

Long-overlooked “tunneling nanotubes” and other bridges between cells act as conduits for sharing RNA, proteins or even whole organelles.

For the first time, researchers see how proteins grab loops of DNA and bundle them for cell division. The discovery also hints at how the genome folds to regulate gene expression.

Mechanical tension between tethered cells cues developing tissues to fold. Researchers can now program synthetic tissue to make coils, cubes and rippling plates.

Compact genomes and tiny cells gave flowering plants an edge over competing flora. This discovery hints at a broader evolutionary principle.

Nobel laureate Susumu Tonegawa’s lab is overturning old assumptions about how memories form, how recall works and whether lost memories might be restored from "silent engrams."

Bacterial biofilms and slime molds are more than crude patches of goo. Detailed time-lapse microscopy reveals how they sense and explore their surroundings, communicate with their neighbors and adaptively reshape themselves.
