The normally single-celled organisms have shown signs of previously unknown multicellular phases. E. coli is a regular resident of our intestines, where it’s mostly helpful, but once it gets out it ...

How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food ...

Physarum polycephalum is an unusual single-celled organism that can grow to be several square feet in size. These massive cells can live in cool, damp areas in temperate forests, and are able to ...

Many cells can use oxygen or nutrients to generate fuel, and the process is similar in many organisms that use an electron transport chain. But scientists have found that in a tiny organism, things ...

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, ...

BUFFALO, N.Y. — They live in bread dough. They die in your oven. At the grocery store, where you buy them, they sit in little glass jars, dormant on the shelf, waiting to be rehydrated so they can do ...

In a series of experiments that began with amoebas -- single-celled organisms that extend podlike appendages to move around -- Johns Hopkins Medicine scientists say they have identified a genetic ...

Single-celled organisms in the open ocean use a diverse array of newly discovered genetic tools to detect light, even in tiny amounts, and respond. Just as plants and animals on land are keenly ...

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 ...
