Last week, I got to visit the Museum of Osteology in Oklahoma City. It's an amazing collection — well worth driving out of your way to see. I was expecting just a selection of different animal skeletons. The actual collection was a lot bigger and more awesome than I'd guessed it would be, and included some really nice exhibits on evolutionary adaptation, convergent evolution, deformed skeletons of both humans and animals, and the process of stripping a body down to a clean and shiny bone structure.
One of the things I found really fascinating was the skeletal features that you can't see just by looking at the outside of an animal. Take this Indian Rhinoceros, for instance. You'll notice that his horn is not a part of the skull. That's because the horn isn't really bone. The "horn" isn't a horn, at all.
Horns are made of bone. They're hard on the outside thanks to a thin layer of keratin — the stuff that makes up your fingernails and hair. But the majority of that material is living bone. Rhinos, on the other hand, have "horns" that are almost 100% keratin. They're really thick bundles of protein fibers.
That's a pretty well-known fact. But it's one thing to know it intellectually, and another thing entirely to see the place where that keratin horn attaches to the animal's actual bone structure. The intricate, lacy network of spongy bone was absolutely fascinating to me. It reminded me of the way ceramic artists will attach one piece of clay to another by scoring little cuts into both pieces and then applying a layer of thin, goopy clay that cements the cuts together as it dries. Seeing the rhino skull really drove home the idea that the "horn" was something else entirely. The horn was attached to the bone. It wasn't part of the bone.
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
