Researchers have found striking parallels between how archaeal cells and more complex cells, including humans' and animals', package and store their genetic material. The breakthrough study provided ...

Tokyo, Japan - Researchers from Tokyo Metropolitan University have successfully determined the high-resolution three-dimensional structure of proteins inside living eukaryotic cells. They combined "in ...

Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged ...

A eukaryotic cell (left) has membrane-enclosed DNA, which forms a structure called the nucleus (located at center of the eukaryotic cell; note the purple DNA enclosed in the pink nucleus). A typical ...

Researchers would like to better understand four-stranded RNA structures called RNA G-quadruplexes (RG4s), which are reported to play key roles in neurodegenerative diseases and cancer. Certain RNA ...

More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the origin of life itself—this merger radically changed the ...

UT Southwestern and University of Washington researchers led an international team that used artificial intelligence (AI) and evolutionary analysis to produce 3D models of eukaryotic protein ...

Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved. Open a basic biology textbook published decades ago or one ...

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 are trying to understand how complex life emerged on Earth about 2 billion years ago. Our microbial ancestors could be the key.

Nuclear magnetic resonance measurement and state-of-the-art computational science reveal protein structures in higher eukaryotic cells. Researchers from Tokyo Metropolitan University have successfully ...
