They tagged these antibodies with a fluorescent dye and then injected them into human cells in the lab. Using powerful microscopes, they spotted a bunch of tiny, glowing, green dots — colored antibodies holding onto elusive i-motifs. read more

The tangled shape, known as an i-motif, had been seen before in the lab, but few researchers expected it to occur in human cells. read more
