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

In an effort to reveal the inner workings of a protein that serves as a cell's damage detection system, scientists at Johns ...

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 ...

Two recently published studies led by Brazilian scientists reveal the key roles of multifunctional proteins, STIP1 and Maspin ...

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 ...

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. In ...

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 ...
