Crystal jellyfish have an eerie beauty: thanks to a natural protein, they emit a faint green glow. For decades, researchers have used that green fluorescent protein and similar molecules to light up ...

We often think of proteins as immutable 3D sculptures. That’s not quite right. Many proteins are transformers that twist and change their shapes depending on biological needs. One configuration may ...

Marc Zimmer received funding from NIH to research fluorescent proteins. Fruit flies, mice, zebra fish, yeast and the tiny worm C. elegans are model organisms that have carried modern biology on their ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

Biophysicists have designed a new cell-like transport system that represents an important milestone on the road to artificial cells. Biophysicists have designed a new cell-like transport system that ...
