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 ...

A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...

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 ...

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 ...

The missing step in the formation of a lipid molecule that allows certain single-celled organisms to survive the most extreme environments on Earth has now been deciphered. This new understanding, ...
