A trumpet-shaped, single-celled organism seems able to predict one thing will follow another, hinting that such associative learning emerged long before multicellular nervous systems ...

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 ...

Research suggests that consciousness could extend far beyond just humans—every cellular creature in the universe, no matter how big or small, could be conscious, too. Studies show that single-cell ...

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 ...

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

Microbes that look like strange deep-sea creatures are turning out to be a missing link in the story of how we got here. There’s a mystery at the roots of the tree of life. There is a hole in the ...

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 ...

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 ...
