Across all species, directed movement is essential for nutrient acquisition, energy harvesting, and the avoidance of danger or sources of stress. Organisms have evolved specific means of locomotion ...

Eukaryotic flagella, whip-like organelles that elegantly propel microorganisms and pump fluid, seem to embody simplicity on the microscopic scale. But appearances can be deceptive: Flagella are ...

Most of us will probably be able to recall at least vaguely that a molecule called ATP is essential for making our bodies move, but this molecule is only a small part of a much larger system. Although ...

Scientists have sequenced the genome of a weird creature that exists as an amoeba until the food runs out, then turns into a two-tailed swimmer to find new hunting grounds. The organism, Naegleria, is ...

For a long time, almost all attention was on the motile cilia because their function was readily observable. But scientists, starting with Alexander Kowalevsky had reported the presence of single ...

Complex life may have had parasitic origins. New evidence suggests that the relatives of the mitochondria within our cells once had a tail, like many parasitic bacteria. Life on Earth is packaged into ...
