Scientists have known for more than a century that a single-celled organism with no nerve cells—much less a brain—can behave ...

The single-celled Stentor coeruleus learns through CaMKII-driven protein modification, mirroring mechanisms found in the human brain.

Scientists have used model organisms to view the first few hours of development in various organisms. A single cell is fertilized, and cell division immediately begins, proliferating into a mass that ...

Up until recently, habituation -- a simple form of learning -- was deemed the exclusive domain of complex organisms with brains and nervous systems, such as worms, insects, birds, and mammals. But a ...

Once, single-cell life claimed sole dominion over the earth. For some three billion years, unfathomable generations of unicellular organisms ate, grew and reproduced among only each other. They ...

Large swaths of single-celled eukaryotes, non-bacterial single-cell organisms like microalgae, fungi or mold, can control microbiomes (a collection of tiny microbes, mostly bacteria) by secreting ...

Discovered: What makes a cell turn fat, the stomach organism that makes us fat, cocaine is bad for the brain, and debunking anti-vaccination myths. What makes a cell a fat cell. This discovery is ...

Researchers have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms. To human eyes, the dominant ...

Most animals require brains to run, jump or hop. The single-celled protozoan Euplotes eurystomus, however, achieves a scurrying walk using a simple, mechanical computer to coordinate its microscopic ...
