A photo taken in the MBL Embryology Course is one of Science's picks!

Our Science Visuals team reviewed the most striking photographs we published this year. Here are the ones that moved us the most. Read more of the article here.

Juvenile of the Longfin inshore squid, Doryteuthis pealei. The F-actin staining (red) reveals the musculature of the mantle; and the acetylated-tubulin staining (green) reveals the tufts of cilia on the surface of the mantle and rest of the body. Nuclei stained blue. Credit: Wang Chi Lau, MBL Embryology Course
The transition from single cell to multicell organisms—a major step in evolution—may not have been as complex as originally thought. Students in the Marine Biological Laboratory in Woods Hole, Massachusetts, use multiple stains to highlight the specialized cells in these delicately constructed juvenile squid, Loligo pealei.
