A graphic representation of a round, lumpy, blue protein and a single, comblike, purple strand of RNA interacting with a twisted, double, blue strand of DNA that separates where it meets the RNA. A ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

A coarse-grained model of the DNA origami lilypad used in the study. The tails hanging down indicate where redox reporters are located. For scale, the diameter of the disk is approximately 80 nm.

A gel held together entirely by interlocking DNA rings exhibits mechanical properties unlike any conventional gel, driven purely by topology.

A nanoscale robotic hand with four bendable fingers can grasp objects like gold nanoparticles or viruses. Xing Wang at the University of Illinois and his colleagues constructed the nanohand using a ...
