There's something unusual about the Chinese soft-shelled turtle. Apparently it's "the only animal to urinate through its oral cavity." Put another way, it pees through its mouth. We know this thanks to Alex Yuen Kwong Ip of the National University of Singapore, who decided to attach tubes to the cloaca of these turtles. He discovered that only a small amount of urea was coming out that way. But when the turtles stuck their head in a bucket of water to take a drink, the urea concentration in the water increased dramatically. [New Scientist]
I never knew how roadkill was disposed of. Turns out that in Maryland the state turns roadkill — particularly deer roadkill — into compost that's scattered by the side of the road. The process: the carcasses are taken to a "deer composting facility" where the bodies are loaded into large wooden bins. Horse manure and wood chips are piled on top. Every week the stuff in the bins is aerated and more manure and wood chips are added. Three months later, it's all moved into the open for curing. The end result is deer compost, which is scattered by the side of the road, helping to grow grass and plants that the living deer eat, until they get hit by a passing car, and the cycle is complete.

University of Queensland PhD student Eduardo Santurtun is conducting research into whether sheep get seasick. Or rather, the effect of "ship motions" on sheep. But he's not studying the sheep on an actual ship. Instead, he's created a contraption (a modified flight simulator) that replicates the roll, pitch, and heave of a ship. His subjects spend hours a day inside this thing being gently see-sawed up and down, back and forth. This is all being done to help the sheep, not hurt them. His research is supported by the Centre for Animal Welfare and Ethics, which is concerned about sheep getting seasick and dying as they're transported from farms in Australia to consumers around the world.

Just when you start to believe in species purity, a find like this in Spain sets the evolutionary world on its head.
The short version is this: modern flamingos nest in a very different way than this recently discovered fossilized flamingo nest.
It seems flamingos and grebes may have nested more similarly in the past than now, and as the article states, they are closely related -- maybe a little too close?
Cartoonist Gus Mager is well-respected for his pioneering newspaper strips. But he seems to have let his fertile and fanciful brain trespass into his supposedly scientific feature for Popular Science. Some of the "facts" given in his column appear somewhat dubious, to say the least. The business about the grapefruit was all settled well before Gus was working in the 1930s.
Inter-species fascination is fun to watch, but if you are the boss, you may be the one who gets to watch the caterpillar.
Did anyone else get the feeling they were considering lunch?
Think about what you sitting there watching this means. One species (us) watching another species(gorillas) watch another species (caterpillar). If we could only know if the caterpillar was watching another species. And don't forget, there is someone out there watching what you are watching. (And probably someone watching them.)
