Crossing the Red Sea with Moses and Open Access

Yesterday the scientific journal PLoS ONE published my article “Dynamics of Wind Setdown at Suez and the Eastern Nile Delta”. This publication represents a portion of my Master’s thesis, which was announced here last year. We now present this research in a peer-reviewed journal. Here is the paper’s Abstract:

Wind setdown is the drop in water level caused by wind stress acting on the surface of a body of water for an extended period of time. As the wind blows, water recedes from the upwind shore and exposes terrain that was formerly underwater. Previous researchers have suggested wind setdown as a possible hydrodynamic explanation for Moses crossing the Red Sea, as described in Exodus 14.

Since the paper is about dynamics instead of biblical history, the contents focus on fluid mechanics instead of on Moses and the Hebrew refugees. But for those readers who are interested in the Exodus, Point B in Figure 8 is Pi-hahiroth. The famous crossing is from Point B across to Tell Kedua. My Tanis hypothesis suggests where and how Moses crossed the yam suf. When remains a thorny issue. As with any new hypothesis, scholars from many disciplines will have to consider the proposal from all angles (history, linguistics, military science, archaeology, meteorology, refugee movement, sociology, oceanography, etc.).

What Open Access means for me

PLoS ONE is an Open Access journal, meaning in a general sense that access to the publications is not restricted. You don’t have to pay a download fee or a subscription fee to download and read the articles. It’s free Free FREE! For what Open Access means for the world of science at large, Google for the term and do some reading. Go ahead and peruse some of the debates. I’ll describe here what it means for me.

It means that my co-author and I paid a publication fee to cover the cost of reviewing and preparing the document for on-line publication. Some journals (Open Access or not) are free to publish in, and others require certain page charges. PLoS ONE follows the “author pays” model.

The “Dynamics of Wind Setdown” article is of general interest. I want oceanographers to read it, I want journalists to read it, I want high school students to read it. I want teachers, gardeners, Norwegians, mechanics, historians, kids, pastors, marketing directors, software engineers, physicists, Australians, poor people, airline pilots, retired people, shepherds, and checkout clerks to read it. I want you to read about the parting of the Red Sea. Skip right to Figure 8 if you want! I don’t want any barriers to readership. I want the paper’s exposure to be as wide as possible. And I can achieve that goal by opening up access.

Peer-reviewed articles are read by scholars, who cite previous research when they publish a subsequent study. The citation count is a measure of the impact of a paper – the importance that a paper has on its field. Open Access papers are supposed to have higher citation counts, so this publishing model will presumably be better for my career.

Leaf Boats and Sediment Traps

Last week we had a big thunderstorm pass over the house during the evening, and my two boys (ages 10 and 6) put on their raincoats and went out into the front yard to see what was going on. They love to send leaf boats down the edge of the street when it rains. When I came out to check on them, they had piled up some landscaping gravel in the gutter to make a dam, causing a large puddle of murky rainwater to collect in the street near our driveway. The two of them were really excited about their civil engineering: “Look, Dad! We made a dam! But our lake keeps rising and flowing around the dam, so we need more gravel!” I grinned. This arms race continued until their dam started to leak through the gravel, kind of like the turbines at the bottom of Glen Canyon Dam. “What? You guys aren’t generating electricity?”

They noticed that the water coming into their little lake was murky with silt, while the water seeping out through the gravel was clear and clean. “Yep, you guys have built a sediment trap“, I explained. “The fast-flowing river water carries dirt with it, but in the calm lake water the dirt drops out to the bottom. That’s why it’s called a sediment trap, because the river sediment can’t get past the lake.” “Wow! We built a sediment trap!” they exulted. “Sediment trapping is a big problem for silty rivers like the Colorado and the Nile“, I elaborated. “The Glen Canyon Dam and the Aswan High Dam trap the river silt and prevent it from flowing downstream. That’s why the Grand Canyon and the Nile Delta are losing their sand.” [Yes, sometimes I talk in html.] The boys were thrilled to hear the world-wide implications of their little experiment.

After the rain we put the gravel back around the mailbox and washed our hands. And I thought to myself, What a great neighborhood / country / life I have! My kids can play safely in the yard, forget their video games, get dirty, have fun, and learn about fluid mechanics all at the same time!

Academic and Choral Achievement

Here is an update since Kevin updated the blogging software. In May 2009 I graduated from the University of Colorado at Boulder with a Master’s degree in Atmospheric and Oceanic Sciences. Wow, five years is a long time! There were quite a few speeches during the graduation ceremony, but I didn’t mind a bit! It took a lot of work to get to that ceremony, and I just sat there in the sunshine with my Master’s robe and mortarboard cap and drank it all in. John Roberts (a CNN correspondent) gave an inspiring address about making your dreams come true. When you come up against a wall, this is your opportunity to show the world how much you want something. If you want your goal bad enough, you will go over, under, around, or through the wall to reach your goal! I feel that I have so much potential, and opportunity, and rich possibilities ahead of me. I don’t ever want to lose that feeling. My sister and family came to see the graduation. Maybe someday when my kids get frustrated with school and homework and term papers and exams they will remember the bagpipes and the funny academic gowns and their Daddy graduating and they will understand that it’s all worthwhile.

Kevin, I don’t know if you wrote a thesis when you got your Master’s degree from Stanford University, or if the co-terminal program had some other option. I wrote a 110-page thesis describing my research and model results:

Title: Application of Storm Surge Modeling to Moses’ Crossing of the Red Sea; and to Manila Bay, the Philippines

Abstract:
Storm surge occurs in low-lying coastal areas when strong winds blow the sea surface up onto the land. The resulting inundation can pose a great danger to lives and property. This study uses an Ocean General Circulation Model and the results from a mesoscale atmospheric model to simulate storm surge and wind setdown. Two case studies are presented. A reconstruction of the crossing of the Red Sea by Moses and the Israelites, as described in Exodus 14, shows that the eastern Nile delta of Egypt matches the Biblical narrative and provides a hydrodynamic mechanism for water to remain on both sides of the dry passage. The vulnerability of Manila Bay and the surrounding areas to a Category 3 typhoon is evaluated and shows that the simulated surge heights depend heavily on the wind direction and the coastal topography.

The thesis document is published electronically by ProQuest, and anyone can download the PDF for a fee and read it. I classified the thesis under Biblical studies in addition to Physical oceanography and Atmospheric sciences. It would be cool to hear a little bell every time someone reads my thesis, but scientific publishing has not reached that stage yet.

I also made the national news for having sung in the Boulder Messiah Sing-Along for 17 consecutive years now. On November 3, 2009 the Associated Press published a news story on Messiah Sing-Along events, featuring the Boulder Messiah Chorale and Orchestra. Hallelujah for Handel’s ‘Messiah’ is by reporter Ann Levin. I am the Enthusiastic Choir Member in the story. If that link ever ceases to work, you can Google for: “Carl Drews” Messiah. Nobody has recognized me on the street yet (“Hey, you’re that Messiah choir dude!”), but it is nice to see that our sound is gone out into all lands, at least electronically.

Done With Coursework

Wow! After 4 years of graduate school I have completed all my coursework for the Master’s Degree. This is amazing to think about! I took one course at a time, focusing on the journey rather than the destination. But here I am!

My thesis year is next. I plan to research my fingers to the bone and defend my thesis in Spring 2009. And then graduate! I enjoyed my classes, and now I’m looking forward to independent research on wind-driven storm surge. If I had started the Master’s program earlier maybe I could have helped those folks in Myanmar to avoid getting clobbered by Cyclone Nargis. But I’m sure there will be other chances to save lives . . .

The University of Colorado web site has this nifty Grade-O-Matic feature that calculates your grade point average whenever you complete another course, and the Grade-O-Tron meter says my GPA is 3.763. I guess I’m not gonna flunk out of grad school after all! I even managed to pull an A- in Fluid Dynamics. Any course with “dynamics” in the title is tough.

My Oceanography class was neat because we used real data and analyzed all the layers in the world’s oceans. Ocean water masses form in certain regions and retain those same properties even when they travel long distances. The Atlantic Ocean is most stratified. For example, here is a meridional cross section of the Atlantic Ocean at 30 degrees West:

http://acd.ucar.edu/~drews/AtlanticSection30West.jpg

That big purple blob descending from the upper left-hand side of the plot is Antarctic Intermediate Water (AAIW). The AAIW water mass stabilizes at about 1000 meters deep and spreads all the way up to 10N. AAIW is cold and fresh from ice melt; cold enough to slide below the warm tropical salty water, but fresh enough to stay above the saline North Atlantic Deep Water. Way cool!

I took a couple of classes on climate and the human affects on same. From what I learned, the vast majority of climate scientists believe the earth is getting warmer, and a smaller majority believe that humans are a major cause of this warming. One of my classes was taught by Roger Pielke Sr., who might be considered a climate-change skeptic (and he’s a real scientist, not like Rush Limbaugh). Dr. Pielke agrees that increased carbon dioxide is a warming perturbation, and that humans produced the CO2 increase. But he contends that land-use change (irrigation, urbanization, agriculture) is a bigger factor in anthropogenic global warming. When you water the desert and farm it, the decrease in albedo (brightness) absorbs more sunlight and warms the planet. Pielke showed some stunning examples of the changes humans have wrought on the land surface! Stunning in terms of the albedo change and the total percentage of the land surface we have have touched (40%). I carried out a simulation experiment on Aboriginal Australia with the Community Atmospheric Model (CAM) that supported Pielke’s contention that land-use changes can be comparable in magnitude to CO2-driven changes, but my study region was too small to apply this finding to the entire globe.

In Genesis 1:28 God tells mankind to subdue the earth and have dominion over all other living creatures. Genesis 1:28 strongly implies that humans can have a very real affect on the planet’s ecosystem, for better or worse. So from the Biblical perspective it’s reasonable to conclude that human activities can indeed alter the global climate. We aren’t big enough individually, but there are 6 billion of us, and we’ve been fiddling with the earth for quite a few years now.

I looked for evidence relevant to carbon dioxide forcing. Can human-raised levels of CO2 really warm the planet? Is there any historical analog to the current situation? The timing of CO2 vs. temperature changes in the Antarctic ice cores is a little hard to determine precisely, because CO2 has a nasty habit of diffusing deeper into the snow before compaction. A good scientific publication is: “Timing of Atmospheric CO2 and Antarctic Temperature Changes Across Termination III”, by Nicolas Caillon et. al.; 14 MARCH 2003 VOL 299 SCIENCE www.sciencemag.org, page 1728. They postulate the following sequence:

1. Time 0 years: Antarctica gets warmer due to orbital forcing (the trigger).
2. Time 800 years: Change in ocean circulation leads to global rise in carbon dioxide.
3. Time 5,000 years: Northern Hemisphere completes its de-glaciation, caused by CO2 amplification of the original orbital forcing.

Caillon states that “the CO2 increase clearly precedes the Northern Hemisphere deglaciation (Fig 3).” One might think that we have 5,000 years to wait before the Northern Hemisphere completely de-glaciates, but don’t get cocky! – Termination III is not a perfect analog to today’s situation. The point is that increased CO2 really can, and has, forced higher global temperatures.

On a final note: Science in action is really good to see! Conclusions really are reviewed, examined, and questioned by other smart people. We scientists are human, but we are committed to finding out the truth. Sometimes the scientific process includes disagreements along the way. I’m excited about my entry into the process!

Movie Review of “Expelled: No Intelligence Allowed”

Last night I went to see Ben Stein’s film “Expelled: No Intelligence Allowed” at my local hexadecaplex. For $9.75 I got to see a terrible movie, and you got this review. I recently served as a guest speaker for an adult Sunday School class entitled, “The Harmony of Faith and Science” at a local Christian church, so this topic is fresh in my mind. I brought a clipboard with me and did my best to take notes in the dark: 5 pages of notes, and 3 more afterwards out in the cinema lobby.

The “Expelled” movie starts right off with an amateurish cinematic device: displaying old black-and-white newsreels of bad historical events while the narrator intones something you’re supposed be scared of. The opening sequence features the construction of the Berlin Wall. Throughout the movie we see clips of tanks, guns, Nazi soldiers, fistfights, a condescending school teacher, even Eddie Haskell beating up The Beaver! – flashing up on the screen whenever Ben Stein talks about Something Bad. When the film makes claims of repression and academic unfairness, you can bet that another old newsreel with scratchy sound is coming. My audience even laughed at a guillotine coming down on an empty block, it was so ridiculous! These clips are a childish device for trying to convince people. I don’t know why anyone over the age of 10 would fall for them.

Anyone expecting a Christian movie here will be disappointed. By my count Jesus is only mentioned in a background song, and the word “Christ” is spoken once. The Bible is mentioned a couple of times, but the Book is never opened. God is mentioned a fair number of times, but mostly in the general sense. The movie contains no in-depth discussion of God’s revelation in the Bible or in the person of Jesus Christ.

The movie reviews at Wikipedia and Scientific American are scholarly reviews, with proper citations and clear reasoning. They leave you with the unfortunate impression that “Expelled” is in the same class of scholarship. But make no mistake - “Expelled” is a really bad movie! Even those bad reviews make the movie sound more sophisticated than it really is. Think of Ben Stein blundering his way through a series of interviews and you’ll have a better idea of what “Expelled” is about.

The movie makes some astoundingly wrong claims. David Berlinski states, “We don’t even know what a species is!” Huh? What has he been reading? A speciesis “often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are often used, such as based on similarity of DNA or morphology.” It is true that species distinctions are sometimes fuzzy, but this fuzziness is evidence for evolution. Berlinski is citing evidence for evolution in the very act of denying that there is any.

I was amused to see how the filmmakers used bad lighting and unusual camera angles to make Richard Dawkins look like a vampire. Dawkins The Vampire appears throughout the movie, the very embodiment of all that is evil in modern science. He even gets his own theme music; my fellow movie-goers were very polite not to holler out “Don’t go in there!” Dawkins The Vampire is extremely useful to Ben Stein for creating Outrage, and this is the same use that creationists have for him.

“Expelled” attempts to make the usual creationist connection between “Darwinism” and atheism. This is bunk. Looking for theology in Origin of Species is a bit like looking for fishing techniques in the Gospels; you can find valid information, but it’s obvious that the main message is something else. Nevertheless, here is how Charles Darwin closed his Sixth Edition:

There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.

The “Creator” is Darwin’s reference to God in the Victorian language of his time. Darwin may be a Deist or an agnostic, but the theological view expressed here is certainly not atheism.

If anyone cares what Adolf Hitler said, here is a quotation from Mein Kampf regarding God:

Hence today I believe that I am acting in accordance with the will of the Almighty Creator: by defending myself against the Jew, I am fighting for the work of the Lord (Adolf Hitler, 1943, in Mein Kampf. Translated by R. Manheim. Boston: Houghton Mifflin. Volume 1: A Reckoning, last sentence of Chapter 2: Years of Study and Suffering in Vienna).

If this blog were a Ben Stein “documentary” we would zoom in on the words “Almighty Creator”, like he does with a quotation by Thomas Jefferson. However . . .

I need to review an important concept for everyone’s benefit: The Christian Church does not formulate doctrine based on the views of Adolf Hitler. The Church does not derive its position on biological evolution by examining the views of Adolf Hitler. The Church does not take a stance on homosexuality based on what Adolf Hitler did. The Church does not learn about the Creator based on what Adolf Hitler wrote, either in a positive or a negative sense. I hope that’s clear now. And by the way, checking against Mein Kampf is not part of the scientific peer-review process either.

My Anglican church uses the Bible to determine doctrine, and the Bible alone. Anglican Article Six states: “Holy Scripture containeth all things necessary to salvation: so that whatsoever is not read therein, nor may be proved thereby, is not to be required of any man, that it should be believed as an article of the Faith, or be thought requisite or necessary to salvation.” So what does the Bible say? Here are some verses from Genesis 1:

11 And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.
20 And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven.
24 And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.

The Bible describes the earth as God’s agent of creation – the earth brings forth life at God’s command. This picture is in accordance with a theistic view of evolution, or BioLogos if you prefer the terminology of Francis CollinsKenneth Miller also holds this view. Genesis 2 emphasizes that life is ultimately made from dirt, which is also in accordance with biological evolution.

Ben Stein raises the possibility that Christianity and evolution are compatible, citing the positions of the Catholic Church and most Protestant denominations, then quickly discards the notion based on quotations by Dawkins The Vampire and a reporter (with glasses; I didn’t catch his name). I don’t know why any Christian would expect theological truth to come out of Richard Dawkins’ mouth. But Stein gets the brief quotes he wants and then quickly moves onward, but not so quickly that he can’t mention the term “liberal Christians”. Later Count Dawkula reads through a list of insulting terms for the God of the Old Testament.

I simply can’t believe the claims of academic unfairness in “Expelled” without further investigation. The movie quickly and firmly establishes its non-trustworthiness through the use of those interspersed newsreel clips. If Ben Stein will do that, he’ll do anything. Here in Boulder we are familiar with the recent case of Ward Churchill, and we know that there is often a large discrepancy between why a person says he was fired and what his employer says. I’m not going to sit there in a movie theater and say, “Gosh this is a “documentary”! Everything must be true!” I recommend reading the Wikipedia article for more information.

During many interviews it’s obvious that the film editors have selected certain short film segments from a larger interview to make that person look bad or stupid. If the subject rubs his nose during the interview you’re sure to see that clip. Ben Stein acts needlessly stupid and looks bored during most interviews. Is this some kind of clever interviewing technique? A particularly stupid comment from Stein is, “I thought science was determined by the evidence, not by the courts!” Kitzmiller vs. Dover did not decide a scientific question; it decided that Intelligent Design could not be taught in the public schools.

There were two people in the film for whom I have great respect: Alister McGrath and John Polkinghorne. McGrath is the author of an excellent book about the King James Bible that you should read. He delivers a convincing and well-deserved criticism of Dawkins The Vampire. The Rev. Dr. John Polkinghorne is a Physicist and an Anglican priest. Elsewhere Polkinghorne has stated: “As all sensible people know, scientific Evolution is completely compatible with Christianity: so is Gravity, Relativity (and the rest of Physics, Chemistry and Biology for that matter).” Stein claims that nobody he interviewed believes that evolution and faith are compatible, but that’s obviously not true.

The tour of the Nazi medical facility at Hadamar was sobering. Ben Stein exploits this event by prompting the tour guide to connect it with Darwinism. The only substantial connection between Darwin and Hitler was to interview Richard Weikart and talk about his book From Darwin to Hitler. But anti-Semitism existed for centuries before Darwin! Even Ben Stein concedes that “Darwinism does not automatically equate to Nazism, but was used to justify it.” And Hitler was a psychopath who would twist any “hodgepodge of ideas” to suit his purposes.

Eugenie Scott comes across pretty well, despite the best efforts of Stein and the film editors. They do manage to show that she has a messy desk. There is very little of substance in this movie.

I was surprised to see Michael Behe, the Apostle of Intelligent Design, neither featured nor even mentioned in the “Expelled” movie. Perhaps he was not invited to appear in the film, or he wisely decided not to have anything to do with this farce.

I expected that the “Expelled” movie would make me angry. Instead, I was chuckling as I left the theater. I was chuckling at how pathetic the movie was! “Expelled” might become a cult film someday: “How Not To Make A Documentary”, or “How To Make A Totally Unconvincing Movie While Looking Like A Buffoon”. “Expelled” is just a terrible movie!

At the very end Ben Stein confronts Dawkins The Vampire one final time. It’s hard for me to believe that Count Dawkula, as smart is he is supposed to be, did not see that he was being set up to be the villain. But that’s exactly what happens. Count Dawkula also fell for the oldest interviewer trick in the book: Stein remains silent, and the evil Count thinks he has to fill in the awkward silence with something. So Count Dawkula rambles into speculation about how if there were intelligent designers who designed this planet, they must also have evolved. But it’s mostly incoherent. Score one for Ben Stein.

A Cosmic Back of the Envelope Calculation

Scientists and engineers love equations. Not only do they make the modern world possible, they can be a lot of fun at parties. At least the kind scientists and engineers throw. And we (I’m just a country engineer) all love a good back of the envelope calculation, which is how one turns a WAG (Wild Assed Guess) into a SWAG (Scientific Wild Assed Guess). So I have to applaud Prof Andrew Watson for this Cosmic SWAG of a calculation:

Is there anybody out there? Probably not, according to a scientist from the University of East Anglia. A mathematical model produced by Prof Andrew Watson suggests that the odds of finding new life on other Earth-like planets are low, given the time it has taken for beings such as humans to evolve and the remaining life span of Earth.Structurally complex and intelligent life evolved late on Earth and it has already been suggested that this process might be governed by a small number of very difficult evolutionary steps.

Prof Watson, from the School of Environmental Sciences, takes this idea further by looking at the probability of each of these critical steps occurring in relation to the life span of Earth, giving an improved mathematical model for the evolution of intelligent life.

….

His model, published in the journal Astrobiology, suggests an upper limit for the probability of each step occurring is 10 per cent or less, so the chances of intelligent life emerging is low – less than 0.01 per cent over four billion years.

I bet that makes him a big hit at all the parties, especially with thePanspermia-ists, who were a pretty lively bunch to begin with.

The Other Metabolic Clock

Or we’ve all got rhythm in our bones, even if it was discovered in our teeth.

Dr. Timothy Bromage discovered a pattern to growth rings in human teeth, and then in our bones as well. Then he discovered them in other organisms, including that lab favorite, the rat:

The newly discovered rhythm, like the circadian rhythm, originates in the hypothalamus, a region of the brain that functions as the main control center for the autonomic nervous system. But unlike the circadian rhythm, this clock varies from one organism to another, operating on shorter time intervals for small mammals, and longer ones for larger animals. For example, rats have a one-day interval, chimpanzees six, and humans eight.

The article links short intervals to small size and short life:

Reporting his findings today in the “Late-breaking News” session during the 37th Annual Meeting of the American Association for Dental Research, Bromage said, “The same biological rhythm that controls incremental tooth and bone growth also affects bone and body size and many metabolic processes, including heart and respiration rates. In fact, the rhythm affects an organism’s overall pace of life, and its life span. So, a rat that grows teeth and bone in one-eighth the time of a human also lives faster and dies younger.”

Humans have by far the most variation in these long-term incremental growth rhythms, with some humans clocking as few as five days, and others as many as ten. Correspondingly, humans have the most variability in body size among mammals.

I assume you have the exact same question I do – namely, do human also have the most variability in life span among mamals as well? Should I be happy that my son, who just turned 14, still has some baby teeth left? Maybe people who live fast and die young are just metabolically programmed that way. Will life insurance companies request a tooth so they can set their rates appropriately? Maybe you should look a gift horse in the mouth.

Who Says Adventure is a Thing of the Past?

Have you ever desired to pit yourself against nature and see who comes out on top?

Have you ever wanted to go off into the wild blue and bring back enlightenment?

Have you ever seen a gladiator movie?

OK, I have a deal for you – join a Russian Arctic drift expedition and spend 7 months drifting around on a piece of ice. You can follow the path blazed by Jürgen Graeser, the first German to take part in a Russian expedition. But floating around on a slab of ice and sending a weather balloon up every day wasn’t all fun and games (unlike playing peek-abo with Polar Bears):

In spite of its importance for the global climate system, the Arctic is still a blank on the data map. Up to now, continuous measuring in the atmosphere above the Arctic Ocean is missing. “We are not able to develop any reliable climate scenarios without disposing of data series with high temporal and local resolutions about the Arctic winter. The data which Jürgen Graeser has obtained in the course of the NP 35 expedition are unique, and they are apt to considerably diminish the still existing uncertainties in our climate models” said Prof. Dr. Klaus Dethloff, project leader at the Alfred Wegener Institute for Polar and Marine Research.

Eh, what’s this, you mean there’s still some real science to be done in Climatology? Say it ain’t so, Al, say it ain’t so.

I have to applaud Jürgen Graeser’s dedication to science. Adventure and learning in one package – what a deal. Who says adventure is a thing of the past?

Funny Bone Meets Thinking Cap

Hot off the press, get it while it lasts — the 2007 Ig Nobel Prizes have been awarded:

  • BIOLOGY: Prof. Dr. Johanna E.M.H. van Bronswijk of Eindhoven University of Technology, The Netherlands, for doing a census of all the mites, insects, spiders, pseudoscorpions, crustaceans, bacteria, algae, ferns and fungi with whom we share our beds each night. No link to her classic lecture ”A Bed Ecosystem,” but you can look it up in the lecture abstracts of the 1st Benelux Congress of Zoology, Leuven, November 4-5, 1994, p. 36. However, if you value a good nights sleep as I do, I recommend against actually reading her work.
  • CHEMISTRY: Mayu Yamamoto of the International Medical Center of Japan, for developing a way to extract vanillin — vanilla fragrance and flavoring — from cow dung. I just wonder why they thought to look for vanillin there in the first place. Toscanini’s Ice Cream, the finest ice cream shop in Cambridge, Massachusetts, created a new ice cream flavor in honor of Mayu Yamamoto, and introduced it at the Ig Nobel ceremony. The flavor is called “Yum-a-Moto Vanilla Twist.”
  • LITERATURE: Glenda Browne of Blaxland, Blue Mountains, Australia, for her study of the word “the” — and of the many ways it causes problems for anyone who tries to put things into alphabetical order. Hey, Microsoft can’t properly order numbers, so we have no hope of handling “The” properly. A maybe, An probably, but not The.
  • PEACE: The Air Force Wright Laboratory, Dayton, Ohio, USA, for instigating research & development on a chemical weapon — the so-called “gay bomb” – that will make enemy soldiers become sexually irresistible to each other. I’m outraged they didn’t include a citation for the fact that this groundbreaking work also examined the desirability of a chemical weapon that created “severe and lasting halitosis” – or that it dates back to at least 1994.

While there is a certain silliness to the these, there is more than a little importance. As the award states, the Ig Nobel is for achievements that first make people laugh, then make them think.

The Skinny On the Skinny Gene

The good news is that yes indeed there is a gene that can keep you skinny. The bad news is that a therapy utilizing it is 10 years away.

Khosrow Adeli, professor of clinical biochemistry at the University of Toronto and Toronto’s Hospital for Sick Children, who studies obesity, called the most recent finding an important one.”Many of the genes we have found so far appear to promote obesity,” he said. “This one appears to basically control it.”

However, multiple factors are involved in obesity, including metabolism, fat cells, liver, and most recently, the brain, Prof. Adeli said.

“We certainly are going to see more of these similar discoveries to fully understand all of the factors involved,” he said, adding that it’s more difficult to design drugs that increase, rather than inhibit, something.

“If one can devise a way to increase activity of this adipose [gene], then it can certainly be very helpful in treating cases of obesity.”

Until then, I’ll be eating whole grain barley for breakfast.

Hey, I’m not overweight, I just don’t provide enough stimulation for my adipose gene.
