Cells can die naturally from age or disease, but organisms can also actively trigger the death of certain cells when needed. This is known as programmed cell death (PCD), a central biological system ...

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 ...

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 ...

A group of researchers has won a large science prize for a discovery not quite two decades in the making. It was long thought that only simple microbes had mastered a chemical conversion reaction that ...

Under the microscope, it is possible to see for the first time how microalgae undergo the same type of programmed cell death as animal cells. (Microalga Guillardia theta in purple and apoptotic bodies ...
