I couldn't resist linking to this piece from The Onion:


(Thanks, Big Gary!)

Not to be outdone by Christian fundamentalists, Islamic fundamentalists have come out with their own anti-evolution treatises. Among the most prominent of these is the Atlas of Creation by Harun Yahya. It's a long work (and more is on the way) consisting primarily of page after page of examples showing that modern-day species can be found in the fossil record. This is supposed to demonstrate that evolution hasn't occurred.

Volume 1 contains the example of the Caddis Fly. The illustration in the book shows the modern-day fly in the foreground. Circled in red in the background is the fossil analogue, preserved in amber. (No, they don't look similar to me either).



But look again at the modern fly. Skeptics noticed it had a steel hook coming out the bottom of it. In fact, it's not a Caddis fly at all. It's a fishing lure created by Graham Owen. Harun Yahya lifted the image (right) from Owen's site, apparently not realizing it wasn't a living creature, and pasted it into his book. Other fishing lures by Owen are scattered throughout the Atlas of Creation.

You can download the entire text of the Atlas of Creation, free of charge, from Yahya's site. So I did, but I couldn't find the Caddis fly in there. (It's supposed to be in Vol 1, p 244). I'm assuming Yahya must have removed it. However, I did notice that in Part 2 of the pdf (page 282 of the text) the Mayfly has a steel hook coming out of its belly. (Thanks, Jona!)

I was working in my backyard this weekend, when I turned over a rock and discovered this creepy-crawly. Anyone have an idea what it is? I wasn't about to mess with it. Looked like it had a stinger on its tail.



Update: Thanks to Robin Bobcat for identifying it as a Jerusalem Cricket. According to the San Diego Natural History Museum: "this nocturnal cricket is actually non-aggressive and possesses no poison glands, although its jaws can inflict a painful bite." Even if it's non-poisonous, I'm glad I stayed away from it. And it's still out there in my backyard somewhere.

Thanks to everyone who emailed me about the Uncontacted Brazilian Tribe hoax that's now making headlines (and is already noted in the forum). I was at the library all yesterday, so I didn't have a chance to post anything.

Anyway, to summarize: Last month the Brazilian government released photographs of an "uncontacted" tribe living in the Amazon. At the time I noted it would be very strange for a tribe to be truly uncontacted, and sure enough this week brings the revelation that anthropologists have known about the tribe's existence for almost one hundred years. From the Guardian:


So the hoax was to describe the tribe as "uncontacted." But it's not that much of a hoax. It's not like the tribe members are actors (as was alleged to be the case with the Tasaday), or are popping over to their local Starbucks every day to get some coffee. The tribe (it seems) truly is living very close to nature and has had hardly any contact with the modern world.

With the price of gas going through the roof, there's been a lot of interest in alternative fuel supplies. For instance, various schemes to use water as a fuel have been getting renewed interest. But a new idea (at least, new to me) is the Diesel Tree. This is a tree that directly produces diesel fuel. All you have to do is tap the tree (just as you would tap a maple tree for its syrup), then fill up your tank with the oil, and you're good to go. From treehugger.com:


You can also check out this video on YouTube in which an Australian farmer who's growing Diesel Trees is interviewed. He admits it "sounds like a fanciful concept," but insists it's real. There are also articles in the Sydney Morning Herald and ABC.net.au.

As odd as the idea sounds, Diesel Trees do appear to be real. Here's the wikipedia article about them. They simply produce a plant oil pure enough that diesel engines can run on it. The Alaska Science Forum notes:

It would be pretty cool to be able to fill up your car directly from a tree in your backyard.(via geoisla)

I recently received a nice letter from a reader in England:


After debating whether or not to throw away her letter (of course not!), I decided to drive up to UCSD, where I hunted down the Veterinary Record (UCSD has a complete run of it), and made a copy of the article.

The article does describe, in a dry, scientific fashion, the diseases of Brunus edwardii, which is described as a species "commonly kept in homes in the United Kingdom and other countries in Europe and North America." The article warns that: "Pet ownership surveys have shown that 63.8 percent of households are inhabited by one or more of these animals, and there is a statistically significant relationship between their population and the number of children in a household. The public health implications of this fact are obvious, and it is imperative that more be known about their diseases, particularly zoonoses or other conditions which might be associated with their close contact with man."

The pictures do give the joke away:



For months afterwards the correspondence section of the Veterinary Record was dominated by letters about Brunus edwardii. A few readers were outraged by it, such as A. Noel Smith who wrote:


But most of the correspondents loved it. It proved so popular that it was eventually published in a special edition by Whittington Press.

Anyway, thanks to M.M. Raymer for the reference.

A recent paper (available as a pdf file) by Vincent Hayward in Brain Research Bulletin lists more than twenty types of tactile illusions that can be experienced using very simple equipment available in any hardware store. Some of the descriptions of the illusions unfortunately are rather technical, but here's a summary of a few of them:

The Aristotle Illusion: Cross your fingers and touch your nose. You may feel two noses. (It didn't work for me.)

The Comb Illusion: Lay your finger on top of the teeth of a comb. With your other hand, run a pencil back and forth against the teeth. You should feel "the sensation of a raised object moving on the finger when, in fact, since the teeth have a constant length, the skin is sheared but indentation is invariant along the line."

The Curved Plate Illusion: Move a plastic card or match box back and forth across the pad of your finger. It should feel straight. But if you see-saw the object up and down as you move it across your finger, it should feel curved.

With the Martian Bigfoot recently making headlines, Dr. Charles Lintott wrote an article for the BBC that traces the long history of Martian pareidolia.

Something about Mars makes us see things that aren't really there. It began with early astronomers believing that the surface of Mars was covered with canals. During the 1960s, some astronomers reported seeing signs of vegetation on the planet's surface.

The image below shows (on the top row) the Martian canals. The bottow row (from left to right) is the "face on Mars" taken by NASA's Viking spacecraft in the 1970s; the fossils that NASA researchers claimed to have found in a Martian meteorite in 1996; the recent Martian bigfoot; and the Martian smiley face (also recently photographed).

Bob (aka Cranky Media Guy) sent me a link to an article about "Scientific Hoaxes" scanned from the Dec. 1931 issue of Modern Mechanix magazine. I love old popular-science magazines like this. They're a great source of strange information.

Unfortunately whoever scanned this article missed two pages, so you skip from a discussion of the Central Park Zoo Escape straight into a discussion of the Cardiff Giant. Nevertheless, the image of a "petrified foot" on the front page caught my curiosity. The caption reads: "A water-worn stone was once offered to the Smithsonian Institute as a petrified foot. Note the striking resemblance."

The article offers no more information about this unusual gift to the Smithsonian. So I did some research in the Google News Archive and was able to find a reference to the petrified foot in a July 18, 1908 Washington Post article titled "Nature as a Faker":


Nineteenth-century newspapers were full of reports of animals and body parts found petrified in their entirety, perfectly preserved, which reflected a popular misunderstanding about the process of petrifaction. Soft tissue is almost never petrified, because it decays long before the petrifaction process can occur.

Dr. James L. Carter has a weird job. He manufactures fake moon dirt. His company, ETSimulants, produces tons of it every year. His primary customer is NASA, who needs fake moon dirt to test machines that might need to operate on the moon. In an interview with Pegasus News Dr. Carter explains:


I'm sure he could make some good money if he put his product in little glass bottles and sold it on eBay. After all, if eBay shoppers will buy genuine air from Loch Ness, they'll also buy fake dirt from the moon.

In order to educate the bus-riding public about the physics of sneezing, Science World created a Sneezing Bus Stop. Watch the video to understand:



They also created posters that can be wrapped around trees to demonstrate how much beavers can eat.

Down in the Antarctic researchers are building an "ice cube telescope" to detect neutrinos. It's one of the stranger telescopes ever built. Popular Science provides this description of it:



But, of course, the conspiracy theorists have some different ideas about what is really being built down there in the South Pole. One such theory has been posted in an unlikely place, explorersweb.com -- a site that's usually devoted to news about the exploration community, not woolly conspiracy theories.

The theory was posted by Irish South Pole skier Kevin Dempsey. Here's the gist of it:



I'm not sure whether or not Dempsey's article is meant to be a joke. Supporting the joke theory is the unusual note that Explorerweb appended to the article: "Dempsey is not a scientist; his emails carry advertisements for stylish blinds and rugs."
