Cheese fungus, head lice, human sperm, a bee eye, a microplastic bobble: scientific photographer Steve Gschmeissner has imaged them all under the probing lens of a scanning electron microscope (SEM).

Gschmeissner, who has been imaging microbes, cancer cells and invertebrates for about 50 years, has crafted an extraordinary array of more than 10,000 SEM images, some of which have been featured in Nature.
He spoke to Nature about the importance of scientific images, looking at imploding cancer cells and the miniature world he found on a rotten rasp
