Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in ...

Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began. Early attempts at team living began to stick, paving the way for the ...

Researchers have discovered and characterized a new organism that will help scientists understand the molecular mechanisms and ancestral genetic toolkit that enabled animals and fungi to evolve into ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they ...

In multicellular organisms, there is a potential risk that cheating mutants gain access to the germline. Development from a single-celled zygote resets relatedness among cells to its maximum value ...

Scaling up from one cell to many may have been a small step rather than a giant leap for early life on Earth. A single-celled organism closely related to animals controls its life cycle using a ...

Scientists discover microRNAs in the unicellular green alga, Chlamydomonas reinhardtii. This is the first finding of microRNAs in a unicellular organism. An international collaboration of researchers, ...

Much more difficult is learning to connect different types of stimuli or events, and predicting that one is linked to another. Such associative learning was most famously demonstrated when Ivan Pavlov ...

If you look at the world around you now - at the plants, animals, and the people around you, it's easy to take for granted our multicellular existence. Life didn't always look like this. In fact, way ...

Unicellular organisms show surprising complexity In a paper appearing in Nature Genetics, researchers discover that in more "primitive" unicellular organisms, both the adenine and the cytosine bases ...
