For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

Super-resolution microscopy, or nanoscopy, enables the use of fluorescent-based molecular localization tools to study molecular structure at the nanoscale level in the intact cell. Analysis of ...

Cells use their molecular architecture to regulate their metabolic functions, and repairing diseased cells' architecture to a healthier state can also repair metabolism, according to a study led by ...

Organelles perform the fundamental processes that help cells (and hence organs, tissues, and organisms) stay alive and operative. In the past several decades, transmission electron microscopy (TEM) ...

In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the ...
