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 ...

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 ...

Bacteria are different from you and me. Always the minimalists, they lack features that plant and animal cells usually can’t do without: a nucleus, special organelles, and an internal skeleton made of ...

Around 1.7 billion years ago, eukaryotes—the building blocks of complex life—first appeared on Earth, and now scientists have ...

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

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 ...

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 ...

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 ...
