Researchers used black enamel paint to block Monarch butterflies use of their antennae. The result: those with antennae covered (ore removed) got lost traveling to Mexico from the U.S. (Those with clear paint on their antennae did fine.) The conclusion is that the butterflies use antennae as both light sensors and clocks that work in conjunction with clocks in their brains.

Map of the Modern World is the name of a course in the Georgetown School of Foreign Service. It’s being reshaped per James Reardon-Anderson, director of the Bachelor of Science in Foreign Service program. The new version focuses on physical geography and its role in international affairs.
Per the school paper: “The changes will be embodied by three lectures on the fundamental forces that shape physical geography at the beginning of the course and a final lecture on global climate change. Reardon-Anderson, who will be teaching the class, acknowledged that the changes are part of the SFS’s effort to increase its students’ exposure to the sciences.”
Students are not pleased. A protest group has sprung up on Facebook with more than 300 members. Some feel political issues will take a backseat to geography.
