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 ...

Just as the human body serves as a habitat for bacteria and other microbes, diverse, tiny organisms known as protists host their own microbiomes. "We know there are many symbionts in the world, but it ...

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria -- the 'powerhouses of the cell,' which generate chemical energy using oxygen. However, a new ...

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 ...

That’s what pops to mind when I look at Sebastian Hess’ photos of a kind of plump, violent, single-celled creature he collected from a pond rich in sphagnum moss in southern Germany. The ...

The rod-shaped tuberculosis (TB) bacterium, which the World Health Organization has once again ranked as the top infectious disease killer globally, is the first single-celled organism ever observed ...

Though they live only a few hours before dividing, bacteria can anticipate the approach of cold weather and prepare for it. The discovery suggests that seasonal tracking is fundamental to life. Every ...

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 ...
