As she was completing her graduate thesis on the neuroscience of vision, Natalia found that she loved to talk to other people about how science impacts them. This passion led Natalia to take up writing and science communication, and she has contributed to outlets including Scientific American and the Broad Institute. Natalia completed her PhD in neuroscience at the University of Washington and graduated from Cornell University with a bachelor’s degree in biological sciences. She was previously an intern at The Scientist, and currently freelances from her home in Seattle.

(Left) The optic lobes are thought to be involved in visual processing. In this study, researchers found that guppies with larger optic lobes more quickly learned a visual discrimination task—identifying which color well contained food. (Right) The fish telencephalon is thought to be involved in spatial learning, memory, and inhibitory control. Here, the researchers found that a larger telencephalon might enhance the fish’s cognitive flexibility, allowing them to more quickly associate food with a new color after the researchers switched it.

In the 1920s, the Institute for Sexual Research in Berlin was a haven for queer people, many of whom came to the institute seeking to express their identities without fear of being imprisoned. This undated photo depicts a costume party at the institute; its founder, Magnus Hirschfeld (second from right, in glasses), can be seen holding hands with his partner, Karl Giese (center).
