Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first ...

Elizabeth Kellogg, PhD, St. Jude Department of Structural Biology, used cryo-EM to study the evolutionary journey of Fanzor2, a compact eukaryotic genome-editing protein with huge potential. (MEMPHIS, ...

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic material (chromosomes) equally, and then rebuild the nuclear envelope around ...

In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...

Scientists have revealed how Fanzor2's divergence from bacterial ancestors may make it a useful tool for future genomic engineering endeavors. A revolution in biomedicine is currently underway, driven ...
