Astronomers use the term dark energy to refer to energy in the universe that is unaccounted for by ordinary matter but ...

Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their blueprint—the genetic information. Here, the basic building blocks of proteins, ...

Particular ice-nucleating proteins produced by certain bacteria have the ability to control the freezing point of water—so efficiently that no other known material can compete. An interdisciplinary ...

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing ...
