Remember the deep-sea "bloop" noise that some people thought might be coming from a giant squid? Turns out it's an icequake. (Here's a WAV of it)

The broad spectrum sounds recorded in the summer of 1997 are consistent with icequakes generated by large icebergs as they crack and fracture. NOAA hydrophones deployed in the Scotia Sea detected numerous icequakes with spectrograms very similar to “Bloop”. The icequakes were used to acoustically track iceberg A53a as it disintegrated near South Georgia Island in early 2008. Icequakes are of sufficient amplitude to be detected on multiple sensors at a range of over 5000 km. Based on the arrival azimuth, the iceberg(s) generating “Bloop” most likely were between Bransfield Straits and the Ross Sea, or possibly at Cape Adare, a well know source of cryogenic signals.

About a month ago, Mike Martin published a profile in Psychology Today, all about Margie Profet, a controversial evolutionary biologist and McArthur fellow who had been missing since 2004. (I posted a link to his story here.)

Now Martin says that Margie Profet has turned up—alive, if not totally physically well. His story led her to realize people were looking for her and to get back in touch with her family.

At the time we lost track of her, Margie was in severe physical pain. Not wanting to trouble anyone else, she did not disclose the fact to us or to her friends, but moved to a new location in which she thought the pain would soon diminish. Instead, it persisted for many years. Unable to work because of it and subsequent injuries, she had long lived in poverty, sustained largely by the religion she had come to early in the decade.

Margie is finally home now, recovering from her long ordeal and hoping to find work in the near future. She is very happy to be reunited with her family, and we are overjoyed to have her back.

This car sits in the lobby of the Royal BC Museum in Victoria, British Columbia. It once belonged to John Lennon, hence the paint job. But that's not the only customization. Inside, apparently, there is a fold-out bed, a portable refrigerator, and a record player. There also used to be a TV. Bear in mind, all these changes were made in the mid-to-late 1960s, when the whole refrigerator-and-TV-in-a-car thing were much more impressive feats of technology.

Sean Rodman works at the Royal BC Museum and sent in this photo, along with a request for assistance. On the roof of the car is a symbol that is, ostensibly, the sign for Libra. Except that it doesn't really resemble the sign for Libra. The Royal BC Museum is confused. Maybe you guys know what this is:

There's no evidence of foul play in the death today of Mexico's Interior Minister José Francisco Blake, but amid the country's raging drug war, there's plenty of suspicion. The helicopter carrying the country's top domestic security official and seven others crashed in the southern part of Mexico City en route to a meeting of prosecutors in nearby Morelos state. The cause of the crash is unknown.

Blake's death is seen as a symbolic blow to the government's military-directed assault on organized crime. 40,000 Mexicans have died in the drug war over the last five years.

The accident occurred almost exactly three years to the day after Mexico’s previous interior minister Juan Camilo Mouriño was killed in the crash of a small plane, also near Mexico City.

Another mysterious detail: Blake's last tweet before the crash was a nod to the anniversary of his predecessor's death.

Reports circulated early today that Mexican president Felipe Calderon had been scheduled to travel in the very same helicopter that crashed, but the administration later issued a statement denying. (via Andrés Monroy H.)

Rose Garrett over at The Bold Italic did some crackerjack investigative work on a little lounge nestled between the bars in the Lower Haight of San Francisco. The Peacock Lounge is almost always closed, only very rarely opened for private events. Rose's attempts to reach someone, anyone, associated with the venue go unanswered until its doors serendipitously open again to host a neighborhood meeting:

Nate also shared with me a detail that went a long way toward explaining why Peacock Lounge was such an enigma. He said the space was not, and was never meant to be, a bar or nightlife venue. It was owned and operated by Unity Masonic Hall, located upstairs, and its main use was as a private social hall for the Black Masons.

Twenty years ago, the United States sent almost 700,000 soldiers to Kuwait and Iraq as part of Operation Desert Shield and Operation Desert Storm. The war was quick. Bombing began on January 17th and the whole thing was officially over by February 28th. If you started a semester of school just before the first Gulf War began, the conflict would have ended before you even took your midterm exams.

But this short war left a long tail of consequences.

Shortly after the War ended, people who’d served in the Gulf began to turn up in Veterans Hospitals, complaining of a range of symptoms: Fatigue, unexplained pain in their joints and muscles, memory problems and cognitive impairment, malfunctioning digestive systems, and more. There wasn’t a clear pattern—different soldiers reported different clusters of symptoms, some of the people who had symptoms had arrived in the Gulf after the fighting ended, other soldiers had boots on the ground from the beginning but no symptoms. As the years went by, epidemiological studies showed no increase in cancers or other deaths in Gulf War veterans, aside from suicides and accidents. Yet, the symptoms were quite clearly linked to service in the Gulf. The same symptoms occur among other groups of military veterans, but are significantly less common. Today, more than 250,000 U.S. veterans report suffering from one or more unexplained symptoms that have, together, come to be known as Gulf War Syndrome. Scientists are still debating the cause, or even if there is one cause.

In the October 2011 issue of the journal Radiology, Dr. Robert Haley and his colleagues at the University of Texas Southwestern Medical Center published research that identified a nervous system abnormality that exists in some Gulf War Syndrome patients, but not in the healthy veterans who served with them. Haley says it’s evidence that the Syndrome is actually the result of exposure to a miasma of toxins, particularly low doses of sarin nerve gas, extremely high doses of various pesticides, and a drug meant to protect users from the effects of nerve gas.
