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 ...

Microglia, the immune cells that protect the brain, are thought to maintain a healthy brain environment by removing unwanted ...

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 ...

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 ...

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 ...

A largely overlooked structure inside our cells may play a crucial role in how the brain forms, offering new insight into ...

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 ...
