(Phys.org)—A team of researchers at Brandeis University in Massachusetts, has found that the CLIP-170 microtuble found in cells, which had been known to be important in cytoskeleton development, binds tightly to formins ...
Researchers said Tuesday they had uncovered fossils showing that complex life on Earth began more than 1.5 billion years ago, nearly a billion years earlier than previously thought.

(Phys.org)—Cell migration is an intrinsic feature of multicellular organisms, enabling such processes as embryo development, wound healing, and immune responses. These activities require cells to move freely within tissues. ...
(Phys.org)—The base-pairing properties of DNA, combined with our abilities to create synthetic DNA in the laboratory have led to advances in nanoscale architecture and molecular device designs. Less research has been done ...
