How does a cow digest its lunch? “Eat, upchuck, chew the barfed-up cud.” That’s just a sample of a weird fact you’ll pick up at the cow station at the Animal Grossology exhibit at National Geographic in Washington, D.C.
This new exhibit is filled with all kind of gross facts. You’ll get the scoop on your cat’s hairballs, a cow’s four stomachs, weird undersea creatures, and more. You’ll also learn the science behind the yucky tidbits so you can explain the fact to your friends! The exhibits are interactive, and there are a bunch of games to play. Special demonstrations held every day will show you the science behind bioluminescence and how germs are spread between people.
Animal Grossology opens at the National Geographic Museum today. The exhibit will run through January 2, 2012.

This picture may look like an ant with antlers, but it’s actually an ant that’s infected with a fungus! This fungus, called Ophiocordyceps camponoti-balzani, is one of four fungi species that infects ants, takes over their brains, and then kills the host ant when it reaches an ideal location for the fungus to grow. The different species of fungi infect ants in different ways. “It is tempting to speculate that each species of fungus has its own ant species that it is best adapted to attack,” said study leader David Hughes, who is an entomologist (or insect scientist) at Penn State University.

Gross but true: Maggots help wounds to heal faster. Some hospitals use maggots to help difficult wounds like ulcers and burns to heal. The maggots eat dead tissue around the wound that can prevent healing and cause infection. Doctors know it works, but how? A new study suggests that maggots secrete a special fluid that helps them to eat the dead tissue.
What does this mean? In the future, doctors may be able to harness the bacteria-busting power of maggots without having to put the creepy-crawlies on people. David Pritchard, a researcher working on the project at the University of Nottingham School of Pharmacy in the U.K., says that putting the liquid in a gel or ointment is the most likely way the liquid will be used. Such a treatment would probably be just as effective as using the maggots.
