First 3-D observation of nanomachines working inside cells

Currently, biologists who study the function of protein nanomachines isolate these complexes outside the cell in test tubes, and then apply in vitro techniques that allow them to observe their structure down to the atomic ...

New signal involved in limb growth found in flies

Many of the secrets of life, such as terminal size and shape, have been uncovered in studies performed over a century involving animal models such as the fruit fly Drosophila melanogaster. Now, IRB Barcelona researchers headed ...

A minimalist theory to predict protein movements

Proteins are large molecules that carry out all basic cell functions. In order to achieve this, they continually change shape by expanding or contracting parts; they hide surfaces or reveal them to interaction with other ...

Two proteins safeguard skin stem cells

Our skin renews, heals wounds, and regenerates the hair that covers it thanks to a small group of stem cells. These cells continually produce new ones, which appear on the skin surface after a few days. A study led by ICREA ...
