September 21st is World Alzheimer's Day, and we dusters are invited to participate in the second annual Stall Catchers' International Catchathon. The Catchathon lasts 48 hours (while it is September 21st anywhere on the planet), but there is a special "Golden Hour" of video competition included.
If you would like to participate in this event (as an individual or a team) or to just learn more, visit www.catchathon.com.
PS. I should mention that stall-catching involves examining live mouse-brain microcapillaries under magnification to determine whether or not blood is flowing through the target vessel. You scroll through the video similar to star-dusting in aerogel, but it is horizontal vs. vertical scrolling. After so many years dusting, that horizontal motion took me a bit of adjustment.

PPS. Dan Zevin graciously provided this link, http://crowdandcloud.org/watch-the-episodes/episode-one , should you like to see the special. The relevant segment encompasses about the 29th to 42nd minutes, and Andrew & Robert appear at about 35 minutes.
