Fly dreams and the boundaries of evolutionary science

In 2002, Secretary of state Donald Rumsfeld made a statement regarding weapons of mass destruction that today is still well known. He famously parsed the evidence (or lack thereof) into "known knowns, known unknowns, and ...

Molecular beacons shine light on how cells 'crawl'

Adherent cells, the kind that form the architecture of all multi-cellular organisms, are mechanically engineered with precise forces that allow them to move around and stick to things. Proteins called integrin receptors act ...

The dynamic cytoskeleton in bacterial cell division

(Phys.org) —The cytoskeletal proteins of eukaryotes polymerize into self-organized patterns even as pure solutions. However, to see more complex dynamics, like filament sliding or rotation, various motor proteins and cofactors ...
