Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...

Both images show individual red blood cells. The one on the right, produced by STED, more clearly shows the Piezo1 proteins (in green), which are a mechanical calcium channel and play a crucial role ...

Scientists have attempted to map the human cell since the first microscope was invented more than 400 years ago. But many components of the cell still remain uncharted. "We know each of the proteins ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

Researchers have developed synthetic genes that function like the genes in living cells. The artificial genes can build intracellular structures through a cascading sequence that builds ...

Proteins are most well-known for their intricate structures. The α-helices and β-sheets that form from interactions between sidechains create distinct shapes that, along with the specific amino acid ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

Northwestern Medicine scientists have uncovered how a specific type of cell in the inner ear plays a commanding role in shaping the cellular landscape of the organ responsible for hearing, according ...

Researchers at EPFL have created CenSpark, a fluorescent probe that selectively labels centrioles and cilia in living cells across species. The tool enables unprecedented live imaging without genetic ...
