Genetiate is a biotech company working on that one thing the world has been crying out for: glow-in-the-dark deer. It's such a bizarre project, that it screams hoax. The amateur quality of its website reinforces this impression. But I think it's real. Genetiate is a division of Geneticas Life Sciences. Those are the same people who, through yet another division, are creating the hypoallergenic cats. But why create a glow-in-the-dark deer? So that it will more easily be seen by motorists. The site gives this explanation:"By implanting the gene of a special jellyfish into deer, the transgenic NIGHTSAVE deer produced by GENETIATE (patent pending) have fluorescing hair and skin when illuminated by car headlights. The implanted gene has no other effect on the deer, who appear normal in daylight." The illogical thing about this is that even if they create a couple of these special deer (or even if they create thousands of them), that's hardly going to have an effect on the wild deer population as a whole, who will still be just as invisible to motorists.
Can Coca-Cola work as an insecticide? Indian farmers seem to think so. The Guardian reports that many of them have taken to spraying their cotton and chilli fields with the soft drink. The article quotes an agricultural analyst who suggests that this might actually work because the sugar in the drink would "attract red ants to feed on insect larvae". But a Coca-Cola spokesman dismisses the entire story as an urban legend: "We are aware of one isolated case where a farmer may have used a soft drink as part of his crop management routine. Soft drinks do not act in a similar way to pesticides when applied to the ground or crops. There is no scientific basis for this and the use of soft drinks for this purpose would be totally ineffective". I'm not enough of a plant expert to judge on whether Coke would work as an insecticide, though it does seem to me like the sugar could actually attract flies (but what do I know?). Plus, I'm not one to criticize the Indian farmers since I regularly throw banana peels around the flowers in my yard in the (perhaps illogical) belief that the peels will somehow keep aphids away.

I've been getting a lot of emails about Allerca, the company that claims it will start selling genetically engineered hypo-allergenic cats in 2007. It may be that they never manage to do what they claim they will do. Or at least, they never manage to do it in commercially viable quantities. But I'm pretty sure they're very serious about trying to do it. But I think they should lower the price a bit. At $3500 a pop, these cats are only going to be for the very rich, considering that you can pick up a cat for free at the pound, and as they themselves admit, female cats are far less allergenic than male cats anyway.
Not being very mathematically inclined, these had me puzzled for a while. The first proof shows that 64=65. It's quite convincing, until you actually get graph paper out (like I did) and try to do it yourself. Then you'll discover that the parts don't match up as nicely as they do in the animation.
A more complicated fake proof can be found here, where 1 is shown to equal 2. I started to go glassy-eyed when I began to analyze the equation, so I quickly broke down and peeked at the answer explaining why the proof is wrong. (via Metafilter)

What caused the Tunguska Event, that massive, nuclear-bomb-strength blast that occurred in Siberia in 1908? A meteorite, is the standard answer. But a few days ago Russian researcher Yuri Lavbin claimed to have discovered "blocks of an extraterrestrial technical device" in the Tunguska area. Lavbin's theory is that a meteorite was headed for the earth, but it was blasted apart by an alien spaceship, thus causing the massive explosion. Why aliens blasting something out of the sky caused an alien technical device to fall to the ground isn't clear to me. Lavbin announced this discovery in Pravda (which is kind of like announcing a major scientific discovery in the National Enquirer). He's transported a piece of this alien device to the city of Krasnoyarsk, though, of course, he hasn't yet allowed the general scientific community to view the thing.
So did he really find a piece of an alien ship? Or has he mistaken a piece of Cold-War-era space debris for an alien ship, as some are speculating? Or has he engineered a massive hoax? As is usually the case, time and scientific access to this 'extraterrestrial technical device' should provide the answer. In the meantime, here's a poll so that you can vote on what you think he's found:

Here's a guy who has fallen a long, long way down. Back in 2002 Jan Hendrik Schön was the soft-spoken boy wonder at Bell Labs, thought to be on a fast-track for a Nobel Prize. He had apparently solved the problem of how to construct a transistor out of a single molecule, which is like the holy grail for building a super-powerful nano-computer. But then his career collapsed when it turned out that 16 out of 21 of his published papers contained bogus data. Remarkably, as investigators studied his articles more carefully, they realized that he had used one particular chart in totally different contexts in a variety of his papers (would it have really killed him to whip up some new fake charts in excel?). Now Schön's alma mater in Germany has stripped him of his doctorate. Ouch. Talk about kicking a guy when he's down.
Back in October 2001 the prestigious Journal of Reproductive Medicine published an article titled "Does Prayer Influence the Success of in Vitro Fertilization–Embryo Transfer?" (the journal appears to have removed this article from its server). The apparent answer to the question posed in the title was 'Yes!' In other words, empirical research appeared to demonstrate that praying could help infertile women conceive. So tough luck if you were an infertile atheist. But a recent article in The Observer reveals that this prayer study was nothing more than a sham. The author of the article, Daniel Wirth, is a serial con-artist, now living under house arrest in California, who possesses no scientific credentials whatsoever. It boggles the mind why the JRM ever published something like this. As Bob Carroll of the Skeptic's Dictionary points out, never mind that the research was fraudulent. The entire premise of it was self-contradictory. He notes:
If prayer works by influencing God to influence the outcome of an experiment, then God can interfere with the laws of nature at any time. If God can interfere with the laws of nature at any time, then no controlled, double-blind study can be sure of the meaning of whatever outcome results. Any result could be the result of direct influence by God. In other words, the assumption the study is based on is self-defeating. No science at all would be possible if God could be interfering with the laws of nature at will. Science requires a backdrop of lawfulness in Nature in order to discover any causal connection between anything and anything else.

A June 8 press release from Purdue University announced that one of its professors, Louis De Branges, has proven the Riemann Hypothesis (don't ask me what that is). This isn't just of academic interest because there's a $1 million prize that'll go to the first person who proves it, so the announcement has gotten some media coverage. The press release cautions that the professor's proof hasn't yet been peer-reviewed, but states that De Branges has posted the proof on his web page so that everyone can see it. But the MathWorld site notes that "both the 23-page preprint cited in the release (which is actually from 2003) and a longer preprint from 2004 on de Branges's home page seem to lack an actual proof. Furthermore, a counterexample to de Branges's approach due to Conrey and Li has been known since 1998. The media coverage therefore appears to be much ado about nothing." (via Gene Expression)
If I just saw this picture randomly out of context, I'd swear it was fake. After all, I've never in my life seen clouds that look like that. But according to the Astronomy Picture of the Day site (which I trust), the picture is real. They're Mammatus Clouds that appeared over Monclova, Mexico. Apparently such clouds sometimes form in turbulent air near thunderstorms.

Head for the hills. The end of the world is near. For the past month conspiracy-theory sites have been all abuzz with the latest scare story: that a comet surrounded by a cloud of dust is going to hit the Earth this month and trigger an end-of-the-human-race scenario. Word of the approaching comet was first leaked on the internet by someone using the screen name 'Aussie Bloke,' who claimed to be an Australian astronomer. You can look at some of his posts over at Bushcountry.org (thanks to Marco Langbroek for sending the link). They make pretty dramatic reading. For instance, here's where he describes the effect that the cometary impact will have:
"There will be several impacts of differing sizes spread over the globe. The bombardment will last a week or so at most. The largest fragment will rock the planet and the smaller ones will wipe out a city here or there depending on where they come down. There WILL be quakes and firestorms and major flooding of coastlines due to ocean impacts. Yes...it will be much like the movie 'deep impact' only worse."
According to Aussie Bloke, there's not much time to get your affairs in order because the dust cloud will begin to reach us tomorrow (June 8), and the first impact will occur on June 18.
Now it seemed pretty easy to dismiss some random guy calling himself Aussie Bloke, but then he decided to reveal his true identity. He said that he was Dr. Grant Gartrell, and sure enough there definitely is a fully credentialed Australian astronomer by that name... who has published articles about meteors and cometary impacts. But unfortunately (or fortunately, rather), that Dr. Grant Gartrell completely denies any knowledge of this 'Impact in June' stuff. In fact, he's been retired from astronomy for quite a while and now spends his time running a blueberry farm, not tracking comets.
It looks like the entire 'Impact in June' hysteria has actually been an elaborate hoax designed to poke fun at the conspiracy nuts. One clue that it was all a joke can be found in the evidence that was presented. For instance, one poster noted that you could tell the comet was approaching because "fireballs have increased significantly over the last several weeks and are happening EVERYWHERE." He then noted that a fireball was seen near Grover's Mill, New Jersey (scroll about a third of the way down the page). Grover's Mill, of course, is where the Martians supposedly landed during the 1938 War of the Worlds Panic Broadcast.

A couple of people have sent me links to this meteor hoax that the AP fell for. The AP reported that a meteor about the size of a small car hit near Olympia, Washington early this morning. Its source for this story was one Bradley Hammermaster, supposedly an Astronomy professor at the University of Washington, who called in a report of the meteor to Seattle's KIRO radio. The AP later had to admit that, "No one by the name of Hammermaster is known to the astronomy department, and the description given by the caller to the station of the object... was clearly bogus." However, it does appear that there really was meteor activity over Washington state, but nothing the size of a small car has been found. This hoax reminds me of a similar hoax perpetrated by the newspaperman Joseph Mulholland back in the 1890s. Mulholland claimed that a meteor had fallen in western Pennsylvania, but he also went on to claim, more dramatically, that it had set fire to much of the surrounding country.
