For a developing frog embryo, gravity is more than the force that keeps it on the ground. It can provide a reference for how the egg is oriented as development begins, helping establish the direction ...

Microtubule asters in cytoplasmic extract of the African clawed frog Xenopus laevis. The spatio-temporal growth of the aster is coordinated by cell cycle waves that drive the polymerization (brighter ...

The lifespan of Xenopus laevis is presented in unprecedented detail using high-quality X-ray microtomography images and 3D reconstructions to reveal embryonic development and metamorphosis processes ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

How does life develop? More specifically, how do human cells organize themselves to form skin, muscles, bones, a brain, a finger, or a spinal column? While the answers remain partially unknown, a ...
