Biomedical research typically follows a familiar path: developing treatments that block, enhance or mutate certain signaling pathways, genes or proteins to change the function of different cells in ...

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 ...

Researchers at the University of Münster and Ruhr University Bochum have demonstrated for the first time in real time that the body's own defense cells use catecholamines—neurotransmitters such as ...

Just like workers need the right environment to efficiently perform their tasks, proteins require placement within specific cellular compartments to function properly. Therefore, understanding the ...

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 ...
