Scientists discover first nitrogen-fixing organelle

Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria ...

Researchers build interactive, comprehensive database of fermentative prokaryotes

Most organisms use oxygen to convert food into energy. However, in environments with little or no oxygen, life found other ways to produce energy, using a process called fermentation.

Why eukaryotes, not bacteria, evolved complex multicellularity

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 eukaryotic cells appeared around ...

Microbial comics: RNA as a common language, presented in extracellular speech-bubbles

Single-celled organisms, such as bacteria and archaea, have developed many ways to communicate with each other. For example, they might use tiny so-called extracellular vesicles (EVs)—membrane-enveloped packages smaller ...

Unraveling the role of supersulfides in regulating mitochondrial function and longevity

Supersulfides are gaining prominence for their occurrence as low-molecular-weight thiols or persulfidated cysteine residues, observed more frequently in both prokaryotic and eukaryotic cells. These compounds, which are characterized ...

Engineers uncover new mechanism for gene transfer

If you still remember that "Dear King Phillip Came Over For Good Spaghetti," you'll likely also recall the corresponding taxonomic ranks of biology: domain, kingdom, phylum, class, order, family, genus and species. The domains ...
