In September and October of 2011, anti-GMO blogs began trumpeting the news that India was suing Monsanto for “biopiracy” (an example). The term biopiracy is something of a weasel word; all it means is the practice of finding useful chemical compounds in plants or animals located in other countries for research purposes, usually for developing new drug therapies based on native plants. Nearly all pharmaceutical companies do this, no matter what country they’re located in. When some group wishes to portray this negatively, it’s called biopiracy.

As you may know, I am a huge proponent of the technology of genetic engineering of crops (full disclaimer). Compared to old-school, trial-and-error cross pollination, GMO is like using a word processor instead of a manual typewriter. It’s the difference between a plant that’s naturally resistant to pests and naturally able to thrive in the native conditions, versus a plant that must be doused with expensive pesticides and fertilizers. So I wanted to know the true story behind these headlines. (continue reading…)

A possible reconstruction of Gigantopithecus.

As Daniel Loxton and I finished our upcoming book on cryptozoology, I needed an image of the famous huge ape fossils from Asia known as Gigantopithecus for the chapter on the Yeti. I emailed my colleague Russ Ciochon at the University of Iowa, who has found many new specimens, and got a rather surprising reply on why he would not share his images with anyone: “Gigantopithecus is not part of cryptozoology. Yet that is the only way anyone hears about Gigantopithecus.” I was rather surprised at his brusque attitude toward a scientific colleague who is on his side, but I can see where he must be fed up with non-stop requests from cryptozoologists who are only interested in his work to support their completely unscientific notions.

The original Gigantopithecus blacki specimens were found in some Chinese cave deposits, first discovered in the 1920s. They include teeth and a complete lower jaw. Unfortunately, there are no other skeletal parts known from this mysterious gigantic ape, despite decades of searching by the large number of Chinese paleontologists who now work on the deposits. More recently, Ciochon has revisited this region, and found more specimens of Gigantopithecus. He did so by shifting his focus to cave deposits in North Vietnam, which are unspoiled by the fossil poachers who robbed the Chinese caves to supply “dragon bones” for apothecaries to grind up into Chinese “medicine”. Still, even after more than 75 years since the first tooth was found, we still have only three lower jaws and about 1300 isolated teeth of this mysterious primate. There is also a second species, Gigantopithecus giganteus, from India, which (despite its name) is about half the size of Gigantopithecus blacki. A third species, Gigantopithecus bilaspurensis, comes from much older beds (6 to 9 million years old) in India, suggesting that the Gigantopithecus line goes back to at least 9 million years ago and the evolutionary radiation of early apes such as the dryopithecines (Ciochon, 1991).

Skeptics sometimes express impatience with discussion of seemingly quaint paranormal claims. (“What, Bigfoot—again?”) But the great lesson of paranormal history is that it is a wheel: no matter how passé or fringe a claim may sound, it is almost guaranteed to come ’round again, in the same form or in some novel mutation.

In the last few days, global headlines have resurrected a nostalgic case from my childhood, just in time for Christmas: “The Shroud of Turin Wasn’t Faked, Italian Experts Say.” The cutting edge of yesterday—today! Even in my youth, this mystery was centuries old.

The Shroud of Turin is a 14-foot length of linen cloth that bears a stylized picture of a bearded man. Legend holds the Shroud to be a burial cloth wrapped around the Biblical Jesus following his execution. This linen was allegedly flash-imprinted with an image of Jesus during his miraculous resurrection, presumably by an intense burst of energy released under such circumstances.

The case for fraud has been strong since the 14th century, but enthusiasts insist on rolling that wheel ’round again. According to news reports this week, Italian scientists used an infrared CO₂ laser to scorch images onto cloth and ”conducted dozens of hours of tests with X-rays and ultraviolet lights” in an effort to prove that the image could be created by a burst of electromagnetic energy. (Here’s a PDF of their Italian-language report.) What is the wavelength of a resurrection miracle? If there is one, the scientists were unable to discover what it might be. They learned (in ABC News’s paraphrase) that “no laser existed to date that could replicate the singular nature of markings on the shroud.” (continue reading…)

We’ve all heard of the code talkers, primarily Choctaw and Navajo native Americans deployed during both World Wars to simply speak over the radio — their language was sufficiently unintelligible to others that true encryption was unnecessary. Here is an article that reports on another group of native Americans employed during the Vietnam conflict for a different purpose: tracking.

I had never heard of this before, so I read the story with interest (and, of course, a touch of skepticism). It begins with a woman who reported that her husband, a psychologist, learned something extraordinary from his patients in the military:

I remember clearly an evening when my husband came back to our apartment on Doctor’s Circle carrying a thick official looking folder in his hands. Inside were hundreds of pages of certain studies commissioned by the government. He was in shock from the contents. What he read in those documents completely changed his life. From that moment on my conservative middle of the road husband grew his hair and beard and never cut them again. What is more, the VA Medical center let him do it, and other very conservative men in the staff followed his example.

Why should psychologists and other professional men suddenly decide to stop cutting their hair? Surely there must be some compelling reason. I read on with interest. (continue reading…)

Today is the northern hemisphere winter solstice  and we’ve already seen a year with many climatic records broken and numerous record-breaking disasters, especially with all the tornadoes and droughts and heat waves. Already the global average temperature estimates for 2011 are coming in, and it looks like it will once again break all previous records for the warmest year in history (which was previously broken by 2010, and before that by 2009). The reports we’re hearing from the media about even more rapidly melting polar ice caps and the vanishing of glaciers around the world are not reassuring.

But in the southern hemisphere, it is summer solstice today, and there the signs are even more ominous. Australia has just gone through years of one climatic disaster after another, capped by 2011 with record flooding, wildfires, drought, and even an gigantic typhoon named Yasi. As this article points out, or an article in the December 2011 issue of Discover magazine discussed, many climate scientists view Australia as a harbinger of the future. It is far more vulnerable to changes in climate than most other regions, since it is a small continent located in the southern high-pressure belt of deserts, with only limited wet areas along the coast and the tropical north. It has few mountains or other topographic features that modify climate or trap rain and snow compared to most other continents, so it can be whipsawed through climate changes much faster than other regions. As the article’s author quoted in an email he received from an Aussie friend, “Welcome to Australia, the petri dish of climate change. Stay safe.” Or as David Karoly, the leading climate researcher at the University of Melbourne, put it, “Australia is the canary in the coal mine. What is happening in Australia now is similar to what can expect in other places in the future. One of the effects of increasing greenhouse-gas levels in the atmosphere is to amplify existing climate signals. Regions that are dry get drier, and regions that are wet get wetter. If you have a place like Australia that is already extreme, those extremes just get more pronounced.”

Which has the Capacity for More Evil? The Creature on the Right or Left?

Haven’t we all had enough of this by now? First we had rabbit’s feet, then Power Balance bracelets came along, now yet another scam. This one gets the media attention on the merit of a dead poodle.

What is wrong with us?

Article quoted from Nina Golgowski:

 Woman blames family’s misfortune on Princess the Poodle who was ‘possessed by the devil’

A New York woman claims her home got more than it agreed to when they brought an adopted toy poodle into their home that was demon possessed. Olga Horvat, a certified Lumia Science Color Therapist and writer of a book Paranormal Pooch writes that her pure-bred dog Princess brought with her a string of bad luck on her home and family.”We had her for four months — May through September in 2006 — and she didn’t want to eat, sleep and she couldn’t be trained to learn simple commands,’ Mrs Horvat told the Huffington Post’s Weird News.’ She was happy, but something was manipulating her,’ Mrs Horvat added. Detailing her efforts to help both her family and her small, fluffy white dog, she asserts in her book, according to the Post’s read, it was not her dog’s fault so they all needed to find help.Her husband next found himself in a serious car accident, nearly lost his job and then fell to a sudden and rare illness almost losing his life, according to her website, RoyalDogsGallery.com. The odds seemed stacked against them ever since Princess entered their household, judging by their timeline, and their woes appeared to be only growing worse. By the time her daughter was nearly expelled from her third-grade classroom for inappropriately touching the arm of a Muslim friend with a glove – according to Mrs Horvat because a voice in her daughter’s head directed her to – her family’s trauma was listless. Perhaps fortunately for Mrs Horvat’s family however, though unfortunate for her dog, Princess died four months after they obtained the poodle.

Foreigners could be forgiven for thinking that America is fast becoming a theocracy. No fewer than three of the remaining Republican candidates (Rick Perry, Rick Santorum, and Michele Bachmann) have declared that they were called by God to run for the country’s highest office. Congress recently voted to renew the country’s motto of “In God We Trust” on nothing less than the coin of the realm. And this year’s Thanksgiving Forum in Iowa (co-sponsored by the National Organization for Marriage) featured most of the major Presidential candidates competing for the title of God’s quarterback.

Rick Santorum, for example, in the course of denouncing Islamic Sharia law, inadvertently endorsed the same as long as it is a Christian on the Judge’s bench: “Unlike Islam, where the higher law and the civil law are the same, in our case, we have civil laws. But our civil laws have to comport with the higher law.” Not content to speak in such circular generalities, Santorum targeted his faith: “As long as abortion is legal—at least according to the Supreme Court—legal in this country, we will never have rest, because that law does not comport with God’s law.” God’s law? That is precisely the argument made by Islamic imams. But Santorum was only getting started. “Gay marriage is wrong. The idea that the only things that the states are prevented from doing are only things specifically established in the Constitution is wrong. … As a president, I will get involved, because the states do not have the right to undermine the basic, fundamental values that hold this country together.” Christian values only, of course.

Joe Nickell has been a working skeptic for a long time, and I am very happy to call him a friend. In writing this post I am reminded of something he said to me that struck me as particularly insightful – (paraphrasing) cynicism is a cheap form of skeptical one-upsmanship. In other words, it’s easy to seem more skeptical than the next guy just by being more cynical. True skepticism, however, is hard intellectual work.

This resonated with me, and brought into sharp focus what has bothered me about many encounters I have had in which someone was chiding me for not being skeptical enough. Sometimes this was coming from a perspective that I would now consider denialism, the specific denial of a generally accepted scientific or historical fact for ideological reasons. At other times the cynical pseudoskepticism was really just paranoid conspiracy mongering. For example, I recently received the following e-mail:

I sort of lost interest in you folks way back when OBL was “killed’” and his body disposed of at sea and photographs withheld, all inviting skepticism but instead skeptics earning nothing but ridicule from your team. I decided you weren’t really skeptical enough about some things, just others. Something about the behavior of otherwise excellent minds in the shadow of a powerful military state with an excellent propaganda apparatus. Except that in this case the propaganda was clumsy, the lies flagrant and out there to see …

The e-mailer is referring to our discussion on the SGU of the killing of Osama bin Laden by US forces. At the time we received many e-mails from those who thought we should taken a more “skeptical” perspective – the position that the US government was lying about the killing of OBL to some extent, and perhaps even entirely. Skepticism regarding the government is a typical context for this sort of response.

This can serve as an excellent example, in my opinion, of the difference between true skepticism and the cheap imitation – cynicism.

Those of us with an interest in the early days of the space race — won by Sputnik 1 in October 1957 — might need to broaden our disciplines a bit to get the whole story. It turns out that the race might have actually been won two months earlier, by the United States, with an entrant from outside the space program. Its name was Operation Plumbbob.

For six months in 1957, Operation Plumbbob put 29 thermonuclear devices to the test in the Nevada Test Range. They were the most varied in the program’s history; all sorts of devices, fired in the air, on the surface, underground, at pigs, near soldiers, and at all kinds of structures. Two of them were particularly interesting. Pascal-A and Pascal-B, on July 26 and August 27, were detonated at the bottom of 500-foot vertical shafts. Both shafts were covered with great heavy steel lids, some four inches thick and weighing some 900 kg. (continue reading…)

I have written frequently in these blogposts about the numerous forms of denial of science and reality that are out there, from global warming denialism, to AIDS denialism, anti-vaxxers, and creationism. They all have a lot in common, from their insular exclusionary attitude that refuses to accept evidence that doesn’t fit their world view, to the various strategies they use to reduce cognitive dissonance and fight against reality, all borrowed from the Holocaust deniers. These include: quoting out of context (“quote-mining”) to dishonestly suggest that the quoted person agrees with them, cherry-picking data to show the exact opposite of what the data really show, making phony lists of “experts” who agree with them, picking on the small differences within the scientific community as evidence that the “science is not settled”, picking on one small factoid (usually misinterpreted and out of context) as evidence that the whole of science is false, and so on. Usually, these obvious strategies to deny an overwhelming body of evidence are so transparently self-delusional that we can laugh at them.

But then I ran into something that staggered even my sense of how low these people can go. We are all familiar with how creationists use ad hoc explanations and special pleading to rescue the absurdities of their world view, from trying to cram all of the animals into Noah’s ark and dismissing the huge numbers problem through their non-biological concept of “created kinds”, to doing all sorts of violence to the geologic record to justify the Noah’s flood story, to even insisting that men have one less rib than do women (the last one is easy to check, but they don’t). As I have discussed in several previous posts, the more extreme Biblical literalists also believe in a flat earth and reject the heliocentric solar system. But I was flabbergasted to read of a whole group of extreme creationists who deny that dinosaurs existed! Usually, the creationists not only come to terms with the evidence of dinosaurs, but many have even tried to co-opt their popularity with kids under 10 by making them a prominent part of their propaganda (as does Ken Ham of the “Answers in Genesis” ministry and the “Creation Museum” in Petersburg, Kentucky). With something as widely accepted and exciting and popular as dinosaurs, which anyone can see for themselves in their local museum, how could any person in the 21st century argue they are not real?
