British bureaucrats offended by “gingerbread man”, rename him “gingerbread person”
Political correctness gone mad: British bureaucrats, offended by the term “gingerbread man” on school menus, had the menus changed to read “gingerbread person.”

Sinkholes on Mars
Caver alert! Releases this week from both the Mars Express orbiter and the Mars Reconnaissance Orbiter show a variety of sinkholes and collapse features on Mars, which in turn suggest the possibility of underground passages.
First, there is this picture from Mars Express, showing the area called Phoenicis Lacus (Latin for Phoenix Lake).
The large and long canyon in box 1 is actually a collapse feature, almost two miles deep and formed as this region was stretched, warped, and cracked by the powerful volcanic activity of the nearby giant volcanoes of the Tharsis plateau, including Olympus Mons, the solar system’s largest volcano. You can also see how this activity causes several sinkholes and craters in all three boxes to become elongated and distorted.
In places where the surface is deformed in this way on Earth, you often find tectonic caves, underground cracks produced as the ground is pulled apart. The large collapse feature suggests the possibility that there are voids below it.
Then there is this subimage from this release of Mars Reconnaissance Orbiter, showing the central peak and southern slope of an old crater in the Terra Sirenum region of the Martian southern hemisphere.
Down that south slope can be seen what look like fluvial-like flows. In the center of these flows as well as near the top of the peak are what appear to be a string of collapse features. Below is the close-up as indicated by the box above:
From the caption: “It is possible that these pits are evidence of subsurface piping or hydrothermal activity. Piping occurs when subsurface water flows through soil, takes some soil with it, and causes the overlying ground to collapse. These fluvial-like features and the connected pits may have formed during a late stage of crater formation when temperatures were suitable for liquid water.”
On Earth, this is one of the geological processes that forms sinkholes on the surface as well as caves underground. When cavers go out to look or dig for new caves, we often head for just this kind of string of sinkholes, as they are excellent evidence that an unentered cave lies hidden below, ripe for exploration.

Vase earns record auction price

Pat Condell on the death of free speech in Europe
Pat Condell, whose never minces words in his commentary on youtube, has decided to speak out about Elisabeth Sabaditsch-Wolff’s upcoming trial in Austria, where she is threatened with three years imprisonment because she expressed an opinion about Islam and the Koran. It is worth watching.
The purpose [of these trials] is to silence dissent, by example. To show everyone else that they too will be treated as a common criminal if they dare to express a negative opinion about the world’s most backward, intolerant and violent religion. This is where we are in Europe today. It’s like something out of the old Soviet Union.
By the way, Elisabeth Sabaditsch-Wolff’s legal defense fund can be found at http://english.savefreespeech.org/ .
EPA sued over ethanol increases in gasoline
The EPA is being sued by oil and grocery organizations over its decision to allow more corn-based ethanol in gasoline. Too bad the EPA didn’t listen to environmental organizations like Greenpeace, who say ethanol in gasoline is bad for the environment.

New airport security checks causing protests
And people wonder why I now drive from Maryland to Chicago: It appears that no one is happy with new TSA airport security checks, requiring either a full body scan or a full body pat down. Protests are coming from pilots, flight attendants, passengers, and the airlines. Key quote from the “passenger” link above:
The aggressively enhanced TSA pat down involves over-the-clothes searches of passengers’ breast and genital areas. You can opt not to go through the backscatter body scanners, and thereby keep your genitalia private from pictures, but then a TSA screener will use a front-of-the-hand, slide-down body screening that Ars Technica called “nut-busting pat-downs.”
And there’s National Opt-Out Day, November 24, 2010. (I wish I could participate, but as I said, I will be driving to Chicago for Thanksgiving, mostly to avoid the police-state of the TSA.)

Mystery missile an optical illusion?
At least one expert claims that the mystery missile launch off the California coast on was merely an optical illusion. Key quote:
John Pike of the security analyst group globalsecurity.org said the video shot by a news helicopter owned by KCBS is an optical illusion. Pike said the video is of an airplane heading toward the camera and the contrail is illuminated by the setting sun. He said the object can’t be a rocket because it appeared to alter its course.
