Gaind and Callaway in Nature:
2019 will be remembered as the year humanity captured the first-ever image of a black hole. The year also brought fresh views of some of Earth’s smallest living creatures and ominous signs of its changing climate. Here are the most striking shots from science and the natural world that caught the attention of Nature’s news team.
Stentors — or trumpet animalcules — are a group of single-celled freshwater protozoa. This image won second prize in the 2019 Nikon Small World Photomicrography Competition, and was captured at 40 times magnification by researcher Igor Siwanowicz at the Howard Hughes Medical Institute’s Janelia Research Campus in Ashburn, Virginia.
