Can a creature with one cell and no brain still learn from experience? A growing body of biology suggests that the answer is no longer easy to dismiss. In experiments on the pond-dwelling protist ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

A recent study has found that a specific single-celled organism has the capacity for Pavlovian associative learning without a brain or even a neuron.

A giant, single-celled organism with no brain, neurons, or nervous system has demonstrated an advanced form of learning previously thought impossible for a solitary cell. The organism is Stentor ...

Animal cell and molecular biology encompasses the study of eukaryotic cells as the fundamental units of life, focusing on their structure, function, development, and the intricate regulatory ...

Scientists at Cincinnati Children's have identified how certain immune cells are molecularly programmed to respond faster when the body encounters a familiar threat, shedding light on immune memory ...
