Myosin II plays the most important role in cellular force generation. Myosin II molecules self-assemble into filaments with different structures depending on myosin II isoforms and other conditions ...

Before arriving at Janelia three years ago, Postdoctoral Scientist Antonio Fiore was designing and building optical ...

Researchers at the Center for Life Sciences at the Paul Scherrer Institute PSI have for the first time identified structural ...

Rhobo6, a light microscopy probe, gives scientists an unprecedented look at the extracellular matrix -- the collection of organized molecular structures that fills the spaces between cells in our ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...

Immunotherapy, which uses programmed immune cells to selectively destroy cancer cells, has transformed cancer treatment.

This is called photosynthesis. The basic structure of a plant cell is shown below. Photosynthesis relies on many structures in the cell all working together, each playing its role. The diagram ...

Cancer stem cells are rare immortal cells within a tumour that can both self-renew by dividing and give rise to many cell types that constitute the tumour, and can therefore form tumours.

Many cells in multicellular organisms are specialised. They have specific roles in the organism of which they are part. Their structure is adapted to their function. They are often grouped ...
