Two images of euglenoid cysts taken under a microscope that look like clear circles with grayish fingerprints inside
Light microscope images of euglenoid cysts from Greece dating between the Holocene and the present era. Researchers recently saw evidence of euglenoids making cysts for the first time.
  • Fabian Weston makes videos of tiny organisms filmed under a microscope.
  • One of his videos provided the missing piece to link 400-year-old fossils with living euglenoids.
  • Euglenoids may be some of the earliest eukaryotes, the domain that includes plants and animals.

Sometimes, it really does help to Google it. Especially when you're a stumped scientist who's exhausted all other angles.

That's what one research team did after all else had failed. And it helped them solve a scientific mystery that's confused biologists for decades.
