Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

Temperatures of minus 196 degrees Celsius enable high-resolution imaging of the cell's interior. Researchers are thus able to show for the first time how the active form of a protein complex plays ...

Biomedical research typically follows a familiar path: developing treatments that block, enhance or mutate certain signaling ...

At the heart of our cells, a previously unknown structure has just been identified, shedding new light on essential biological mechanisms. This discovery could transform our understanding of certain ...

In 2015, researchers at UC San Francisco found a structure inside of tumor cells that biologists had never seen before. Even more surprising, a closer examination of the structure revealed that it ...

More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the origin of life itself—this merger radically changed the ...

A new study led by Claus M. Azzalin, group leader at Instituto de Medicina Molecular João Lobo Antunes- iMM and published today in the prestigious scientific journal Proceedings of the National ...

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study.

A previously unknown structure discovered in our cells could pave the way toward new treatments for various genetic disorders. The existence of the organelle—which has been dubbed the "hemifusome"—was ...
