Researchers have captured the moment two DNA molecules zip together, overcoming their identical negative charges to pair up and revealing a mechanism that has puzzled scientists for more than 20 years.

A record player-like microscope and computer simulations solve a longtime mystery, showing that metal ions bridge DNA strands that would normally repel.
