The Curious Case of the Nonexistent Turtle

With all the stories about “de-extinction” of animal species lately, there’s one method that doesn’t get much notice -when scientists decide that an extinct species never existed in the first place. That applies to the case of Pelusios seychellensis , which, according to specimens collected by German naturalist August Brauer over 100 years ago, lived in the Seychelles off the east coast of Africa. Curiously, these turtles closely resembled turtles on the west coast of Africa, Pelusios castaneus . But they couldn’t be the same, because they lived so far apart. So the separate species name was coined in 1983. But even more curious, no one could find any specimens of Pelusios seychellensis in the Seychelles, and scientists concluded that the species had gone extinct during the 20th century. Not only that, they assumed that humans had caused the extinction. But wait… Brauer took the trip during which he was supposed to have collected the turtles between May 1895 to January 1896. But he didn’t immediately give his finds to a museum. Specimens from his private collection didn’t get transferred to the Zoological Museum Hamburg until five years after the Seychelles trip, and those turtles soon went on to Vienna’s Natural History Museum. Somewhere in all that shuffling, the west African turtles might have been lumped in with the Seychelles reptiles or otherwise confused. Whatever happened, though, a prominent clue indicates that the turtles were not collected from the wild. One, and possibly two, of the turtles have a perforation through their shells identical to the sort that turtle purveyors have traditionally used to tie turtles together until they are sold for food. Wherever Brauer got the turtles from, he seems to have purchased them. Oops. On the bright side, this means that humans did not cause the extinction of a turtle species, because Pelusios castaneus is still around -on Africa’s west coast.

Look How Quickly the U.S. Got Fat

Watch this CDC map change from 1985 to 2010 -and get more colorful along the way. It shows the percentage of people medically defined as obese. Obesity was once an odd condition, but for the U.S. it just gets more common every year. The Atlantic has a list of the metropolitan areas that have the lowest and highest rates of obesity. Moving to Colorado will only help if you are willing to climb mountains, hike, and ski. Link

Icefish Bleeds Clear Blood

The ocellated icefish you see above has a very unique blood: it’s totally transparent. Discovery News tells us: The reason, say experts at Tokyo Sea Life Park, is that the Ocellated Ice Fish has no hemoglobin, making it unique among vertebrates the world over. Hemoglobin is the protein found in every other animal with bones. It is what makes blood red and is the agent that carries oxygen around the body. Researchers believe the fish can live without hemoglobin because it has a large heart and uses blood plasma to circulate oxygen throughout its body. Link

The Startling Rise of Disability in America

As the American economy has moved away from manufacturing to information services and the economy limps along, not keeping up with the number of people who need jobs, the U.S. Social Security Disability program has boomed. This boom covers up the real numbers of people who would otherwise be on welfare or counted among the unemployed. NPR looks at several factors that made this happen: for example, disability is for people who can no longer perform heavy labor, and don’t have the education or skills for other jobs. One woman I met, Ethel Thomas, is on disability for back pain after working many years at the fish plant, and then as a nurse’s aide. When I asked her what job she would have in her dream world, she told me she would be the woman at the Social Security office who weeds through disability applications. I figured she said this because she thought she’d be good at weeding out the cheaters. But that wasn’t it. She said she wanted this job because it is the only job she’s seen where you get to sit all day. At first, I found this hard to believe. But then I started looking around town. There’s the McDonald’s, the fish plant, the truck repair shop. I went down a list of job openings — Occupational Therapist, McDonald’s, McDonald’s, Truck Driver (heavy lifting), KFC, Registered Nurse, McDonald’s. And disability payments shift the expense of maintaining people without jobs away from states and onto the federal government. A person on welfare costs a state money. That same resident on disability doesn’t cost the state a cent, because the federal government covers the entire bill for people on disability. So states can save money by shifting people from welfare to disability. And the Public Consulting Group is glad to help. PCG is a private company that states pay to comb their welfare rolls and move as many people as possible onto disability. “What we’re offering is to work to identify those folks who have the highest likelihood of meeting disability criteria,” Pat Coakley, who runs PCG’s Social Security Advocacy Management team, told me. Other factors come into play, but the result is that 14 million Americans receive a disability check every month -and health care through Medicare. Learn more about the trend at NPR. Link

The Fangweng Restaurant

The Fangweng Restaurant in Hubei Province, China, is located conveniently near the popular Sanyou Cave tourist destination. But what may strike you as more impressive is that the eatery appears to hang on the side of a cliff! If you didn’t know this ahead of time, you might be surprised, because the entrance gives no clue. You must walk down a passageway that juts out over the Happy Valley of the Xiling Gorge to get to the dining hall. Once there, most of the tables are safely inside a cave, with just a few on a ledge over the chasm. Read about this restaurant and see more pictures at Spot Cool Stuff.

7 Weird and Wonderful Facts About the Wizard of Oz Books

The new movie Oz the Great and Powerful opens today in theaters nationwide. The backstory of the wizard is loosely based on the L. Frank Baum book The Wonderful Wizard of Oz . Baum went on to write 14 more books about Oz, because the public kept demanding more. An interesting fact I didn’t know -one of his granddaughters was named after an Oz character!   Baum had a granddaughter named “Ozma,” and his 11th Oz book, The Lost Princess of Oz (published 1917), was dedicated to her shortly after her birth. The story begins with the disappearance of Princess Ozma, the ruler of Oz.    Read more interesting facts about Baumm’s Oz books and see artwork from all of them at Tres Sugar. Link   -via Holy Kaw!

Circular Beam of Electrons

Beam of electrons moving in a circle, due to the presence of a magnetic field. Purple light is emitted along the electron path, due to the electrons colliding with gas molecules in the bulb. (Photo: Marcin Bialek ) Oh, how I love you guys. In our recent post A Fiery Dance on the Sun , Neatoramanaut PlasmaGryphon kindly took the time to explain to us the physics behind solar flares. In the explanation , there was a link to Wikipedia article on Lorentz force , where I found this fascinating image of a circular beam of electrons in a Teltron tube . Neat, huh? ( Thanks PlasmaGryphon! )
