Hello Foldscope community. Over the course of 48 hours, using the amazing Foldscope, I documented the embryonic development of a sea urchin. Thanks to my Foldscope and my refrigerator, during this time of COVID-19 I can still do research from the comfort (and safety) of my home. Check out these images! I collected the sperm and embryos from spawning urchin at my work.
