and they are believed to have originated back when all living things on Earth were single-celled organisms. At that time, some larger eukaryotic cells with flexible membranes "ate" by engulfing ...

How did eukaryotic organisms become so much more complex than prokaryotic ones, without a whole lot more genes? The answer lies in transcription factors. Experiments have shown that TFs can bind ...

Princeton University and Xiamen University researchers report that in tropical and subtropical oligotrophic waters, ocean ...

For Nate Cira, assistant professor of biomedical engineering in Cornell Engineering, the tiny eukaryotic organism provided inspiration for modeling "traveling networks"—connected systems that ...

Genetic material DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or more rings ...

Bacteria and other single-celled microorganisms in the seas around Antarctica are strongly influenced by water temperature ...

The mechanism differs from membrane fusion by eukaryotic organisms or viruses. In eukaryotic organisms, for example, Dr. Paumet compares membrane fusion to a zipper, where the cellular machinery ...
