For those who may have come to the Loom after seeing me talking about autumn leaves on ABC News this evening, you can learn more about the science in these posts (plus this article I wrote for the New York Times). Scientists continue to investigate why leaves change colors--check out this new post yesterday from Voltage Gate. (I should also clarify that the damage leaves suffer in the fall can come from charged atoms within the leaf, rather than directly from the sun's photons.) Update: Link to the ABC news segment added.
