When you picture a single cell, you probably imagine something super tiny that you had to look at through a microscope. But, there are some huge exceptions to this rule. And we really do mean huge!

Add Yahoo as a preferred source to see more of our stories on Google. A light microscopy image shows the marine algae Braarudosphaera bigelowii, which is a potentially large evolutionary step. This ...

All life on Earth came from one common ancestor – a single-celled organism – but what it looked like, how it lived and how it evolved into today's modern cells is a four billion year old mystery being ...

A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate ...

Too much of a good thing is no good at all. Living organisms enjoy sunlight -- in fact, many need it to stay alive -- but they tend to avoid light that is too bright. Animals go to their shelter, ...

Imagine if your neck was so extendible that your head could reach your local shop while you sat on the sofa. That would be the human equivalent of what one single-celled predator can do – and now the ...

A single-celled marine plankton evolved a miniature version of a multi-cellular eye, possibly to help see its prey better, according to University of British Columbia (UBC) research published today in ...
