The wall surrounding Oxford Castle has anti-climb paint on it. At least that is what this ominous sign warned me of as I walked past it late one Friday night while I was stranded under the ash cloud. Of course, the rock climber in me was tempted to climb the forbidden wall; a few seconds later, the cops were yelling at me to get down, and I had to apologize so they wouldn't arrest me. "What is anti-climb paint, anyway?" I asked them as I ducked away into the darkness. "Does it work?" After all, I did get up the wall without much of a problem.
The cops (who weren't really that mad) told me that anti-climb paint is kind of like pigeon glue; it has a long-lasting viscosity that makes surfaces sticky, slippery, and just plain unpleasant to perch on. It also sticks to human skin, so back in the day you'd be able to identify burglary attempts by checking the suspects' fingers. But, they said, "it might not be working anymore"; it's been a long time since people actually tried to break into Oxford Castle, which is now a tourist destination.

One of the weirdest places in Antarctica is Blood Falls, a five-story cascade of blood-red liquid pouring from Taylor Glacier. Researchers finally traced its source: a saltwater lake millions of years old trapped under the glacier.
Fetal lambs survived for weeks in an experimental artificial womb, and scientists hope that the breakthrough could lead to new treatments for premature babies and perhaps the dreamed-of machine utopia where humans are kept mindlessly writhing in translucent plastic sheaths filled with psuedoamniotic liquid. Physicians at the Children’s Hospital of Philadelphia placed fetal lambs into […]

All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
