Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

In a world first that challenges what we thought we knew about biology, scientists have successfully engineered animal cells that can photosynthesize. The breakthrough promises to revolutionize ...
