Mind the gap: Space inside eggs steers first few steps of life

Imagine sitting at a meeting where the shape of the table and your place at it might impact how you get along with the other members. Cells also communicate with their nearest neighbors, and in embryos, nothing is left to ...

Unraveling the origins of the human spine

The spinal column is the central supporting structure of the skeleton in all vertebrates. Not only does it provide a place for muscles to attach, it also protects the spinal cord and nerve roots. Defects in its development ...

The meat, the muscle, and the motion of cell fusion

One day Prof. Eldad Tzahor peered into a microscope in his lab and saw steak. As part of Tzahor's research into repairing muscle tissue, Dr. Tamar Eigler, a postdoctoral fellow in his lab at the Weizmann Institute of Science, ...

First evidence of microtubules' mechanosensitive behavior

Inside cells, microtubules not only serve as a component of the cytoskeleton (cell skeleton) but also play a role in intracellular transport. In intracellular transport, microtubules act as rails for motor proteins such as ...

Exploring how organs develop

Scientists from the department of Anatomy and Embryology at the Faculty of Medicine of the University of Tsukuba created a computer model to simulate the development of complex structures based on the Delta-Notch signaling ...

Understanding what drives cell typing

Scientists know that developing cells in a healthy embryo will transform into a variety of cell types that will make up the different organ systems in the human body, a process known as cell differentiation. But they don't ...

Hi-CO unravels the complex packing of nucleosomes

Scientists at Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) in Japan have developed a technology that produces high-resolution simulations of one of the basic units of our genomes, called the ...
