Jerry Coyne posted the photograph on the right and said, "If you don’t know what happened a few minutes after this picture was taken in 1969, you are either way too young or have no knowledge of rock history" [Music history about to be made]. I agree but, unfortunately, there are way too many people who are way too young. You can't blame them for not knowing what was about to happen.
I've been on that crosswalk dozens of times because it's right near a house in St. John's Wood where I once stayed while in London. Here's a photograph (below) of the owner of that house along with some of his friends. You don't have to be very old to have been around when this photo was taken but you do have to have some knowledge of the history of biochemistry and molecular biology.
How many of you can name all the scientists in this photo? (No peeking at the comments.)
John Hawks is a big fan of online education. He posted a link to a Wall Street Journal article about online education [Online education and Silicon Valley]. The article, Sebastian Thrun: What's Next for Silicon Valley?, is mostly about a Stanford professor and Google employee, Sebastian Thrun.
The entrance to his building is littered with the gaudy red, blue, yellow and green bicycles that Googlers tool around on. I'm at the secret headquarters of the not-so-secret Google X, where the way-out-there projects of the search giant turn into reality. The gregarious play master, Sebastian Thrun, leads us into a well-worn conference room. The chairs are a shade of green not found in nature and the disrupting clang and cheers from a rousing foosball game waft in through the door. Mr. Thrun, 45 and slight in stature, is sporting a gray T-shirt of a local start-up and speaks softly with German-English diction.
Thrun and his Google colleague, Peter Norvig, taught an online course on artificial intelligence that attracted a huge number of students. Apparently there were 23,000 students who completed the course. That's amazing. But there's more ...
Mr. Thrun's cost was basically $1 per student per class. That's on the order of 1,000 times less per pupil than for a K-12 or a college education—way more than the rule of thumb in Silicon Valley that you need a 10 times cost advantage to drive change.
So Mr. Thrun set up a company, Udacity, that joins many other companies attacking the problem of how to deliver the optimal online education. "What I see is democratizing education will change everything," he says. "I have an unbelievable passion about this. We will reach students that have never been reached. I can give my love of learning to other people. I've stumbled into the most amazing Wonderland. I've taken the red pill and seen how deep Wonderland is."
How in the world do you pay attention to 23,000 students and give them a grade that reflects what they learned for only $23,000? The only way you could do that is to have all assignments and tests evaluated electronically and that's no way to teach properly. (You also need very cheap servers, internet access, and software and Thrun and Norvig have to work for free.)
Udacity is a for-profit company. How will it make money? [Ex-Stanford Teacher’s New Startup Brings University-Level Education To All].
Classes are currently focused on computer science since that’s what the team already knows how to teach. Examples include: Building a Search Engine and Programming a Robotic Car. As one of the inventors of Google’s self-driving car, Sebastian is perfectly suited to teach a class on how to program one. Udacity plans to expand to other subjects with the goal of building a full university online.
All classes are currently free, and the goal is to keep it that way. When asked how it will make money, Sebastian pointed out that recruiting good technical talent is something that companies pay for. Udacity knows who the best students are and could pass them along to companies looking for new hires.
Somehow I doubt that Udacity will be offering courses in philosophy, French, or art history. I don't even think they'll be teaching biochemistry since very few of our undergraduates move directly from a Bachelor's degree to jobs in biotech or pharmaceutical companies.
Sebastian Thrun thinks he's going to "democratize" education but, if he succeeds, what he's really going to do is dumb down and cheapen education. The only thing in his favor is the fact that today's universities are doing the same thing so creating online courses is probably no worse that what students are currently getting in the classroom. If someone can offer the same quality of "education" for much less money then what's the point of attending classes?
Nick Lane has written a very nice article in the June 23, 2012 issue of New Scientist: Life: is it inevitable or just a fluke?.
Nick Lane is a biochemist who works on the origin of life at University College London (UK). He's also a science writer who recently won the Royal Society Prize for Life Ascending: The Ten Great Inventions of Evolution. His new book will be called, CHASM: The Outlandish Origins of Complex Life.
Lane is one of the main proponents of the "Metabolism First" view of the origin of life. The idea is that life began with the evolution of an energy source much like the main source of energy in today's cell. The energy is derived from a gradient of proton concentration across a membrane. This was first discovered by Peter Mitchell (chemiosmotic theory) and it was one of the most important discoveries in biochemistry—although most people, including most biochemists, haven't got a clue what it's all about [Ode to Peter Mitchell] [Why Are Cells Powered by Proton Gradients?] [Metabolism First and the Origin of Life ].
The ability to generate usable energy in this manner could have arisen near thermal vents in the ocean where the gradient exists between the alkaline interior of small cavities in the rock and the external seawater. The energy was then used to build up small organic molecules such as sugars and amino acids. Early metabolism arose when pathways for the simple molecules of life evolved using simple inorganic catalysts and/or simple peptide catalysts. "Metabolism First" is a much more reasonable scenario, in my opinion, than "Prebiotic Soup" [More Prebiotic Soup Nonsense].
If this view is correct then the origin of life depends only on the presence of simple chemical systems that create an energy producing gradient and this is likely to happen on many planets. However, the leap from simple cells to complex cells may have been the rate-limiting step in the evolution of sentient beings.
Lane suggests that large complex cells with large genomes could only have arisen if they discovered an abundant source of energy. That happened when some simple bacteria formed an endosymbiotic relationship with bigger cells to create a new life form with mitochondria [Energetics and genetics across the prokaryoteeukaryote
divide]. This unique event was not inevitable. It happened only once in the history of life—about 2 billion years ago. This sort of lucky accident may never occur on other planets so it may just be a fluke that sentient beings evolved on Earth.
We may be alone in the universe.
Today's molecule has a common name and a much less common systematic (IUPAC) name. You need to supply both names in order to win. You also need to tell us what this molecule does.
Post your answer as a comment. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch with a very famous person, or me.
There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.)
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!)
In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.
Winners will have to contact me by email to arrange a lunch date.

Natural Selection in the Wild: from Genotype to Phenotype
Here's the list of sessions with "Random Genetic Drift" or Neutral" in their titles.
Isn't that strange? There are many more neutral alleles than beneficial alleles and random genetic drift is overwhelmingly the most common mechanism of evolution. I guess most evolutionary biologists have a huge bias toward studying adaptation. One can't help but wonder how many studies were abandoned when the investigators discovered that they couldn't prove natural selection was involved.
Why weren't those studies completed and published as examples of random genetic drift?
There are more than one thousand talks being given at this meeting and only five (5) have the word "drift" in their title—and one of those is about education!
Michael Ruse wrote a book called Science and Spirituality: Making Room for Faith in the Age of Science (2010). It's a defense of accommodationism—the position of atheists who maintain that science and religion are compatible because they are different ways of knowing. Ruse is one of the main proponents of Methodological Naturalism, which postulates that science is restricted, or limited, to investigations of the natural world. Since religion deals, by definition, with the supernatural world, it falls outside the domain of science and is, therefore, compatible with science. This leads Ruse to define several criteria of Christianity that are immune to scientific investigation [The Essence of Christianity].
This position used to be overwhelmingly accepted by the majority of scientists and philosophers, especially in America. It has become the standard view of most professional scientific organizations and of The National Center for Science Education (NCSE). It's a convenient way for atheist scientists and religious people who are mostly accepting of science to avoid conflict as they make common cause against the extreme creationists.
But that view is now being challenged and it's no longer acceptable to claim that it represents the only view of science. That's what the good guys did during the Dover trial a few years ago but it wouldn't work today because there are dozens of prominent philosophers of science who would argue against such a limitation of science.
One of them is Peter Slezak of the School of History and Philosophy, University of New South Wales, Sydney, Australia. He recently wrote a review of Ruse's book: Michael Ruse: Science and Spiritutality: Making Room for Faith in the Age of Science (Slezak, 2011).
Much of the conflict depends on definitions and Slezak clearly endorses a much broader view of science than Ruse. Here's how Slezak challenges the view that science has limits.
This is a widely held and obviously appealing line to adopt for those, like Ruse, who are committed to the scientific enterprise and its claims. However, I will suggest that, despite its appearance of open-minded ecumenicalism, the posture faces insuperable intellectual difficulties. In wishing to leave room beyond ‘‘the allowable scope of science’’ (p. 235), Ruse is effectively endorsing a traditional demarcation between science and metaphysics in order to restore respectability to some claims in the latter category. However, this recidivist project does not properly address the hegemonic nature of the scientific enterprise. This conception is expressed in the final remarks of Bertrand Russell’s (1935) book Religion and Science. Aside from questions of value that lie outside the realm of truth and falsehood,
Russell says:
Whatever knowledge is attainable, must be attained by scientific methods; and what science cannot discover, mankind cannot know (1935, p. 243).
The title of Freud’s (1927, 92) book The Future of an Illusion refers to religion and ends with the exactly the same sentiments: ‘‘an illusion it would be to suppose that what science cannot give us we can get elsewhere’’. These expressions of a positivist conception are less dogmatic than they appear because they may be understood as statements of the openmindedness of science rather than its opposite. That is, ‘‘science’’ doesn’t exclude anything simply because the honorific label is used for anything worth believing. That is, if there are any rational grounds for a proposition, it will become included within the domain of established science. Or, rather, perhaps we should say that it will be included on the spectrum of claims ranging across ‘good, bad and bogus’ to use the sub-title of Gardner’s (1981) book. The point is captured in Laudan’s (1983) account of the ‘‘Demise of the Demarcation Problem’’ since he shows that ‘‘the problem of demarcation … is spurious’’ and the heterogeneity of beliefs and activities means that there are no lines to be drawn (see Special Issue of Science & Education, 2011, volume 20, 5–6). In particular, this means that the claims of religion fall somewhere on the spectrum, arguably nearer the bogus end. However, this means that they are subject to the usual criteria for deciding what is worth believing, which is, in any case, clear enough from the nature of the claims as we will note presently.
Ruse and his allies believe that any attempt to step outside the limits of science constitute a venture into metaphysics and this is not science but something else. Peter Slezak rejects this argument ...
Plantinga (1991, 8) suggests that the question of the clash between faith and reason is ‘‘enormously difficult’’ requiring ‘‘penetrating grasp of the relevant theological and philosophical issues’’ as well as the complex science. However, this is sheer bluff since the arguments don’t depend on any such arcane knowledge. Thus, citing Plantinga, Ruse (p. 183) seeks room for claims alongside and independent of science on the grounds that there are alternative ‘‘world views’’ and, therefore, a choice between two ‘‘metaphysical’’ options— naturalism and theism. The air of reasonableness and even profundity in this stance produces a vacant illusion of explanation but disguises sophistry. First, even if we are to talk this fancy philosophical way with Plantinga, it remains obscure why the Christian theistic ‘‘metaphysics’’ is the only alternative to the ‘‘naturalistic’’ one. One could presumably find or invent many others that would have equal status as alternatives to naturalism by virtue of having nothing to recommend them. Does Plantinga think that Mexican metaphysics based on the theology of Quetzalcoatl deserves equal consideration with his Christian variety?
The very idea that we can transcend what Ruse calls the ‘‘limitations of a science based knowledge’’ (p. 10), or that we have a choice between alternative ‘‘metaphysics’’, is an illusion. There is no alternative to our best theories other than worse ones. Naturalism is just the picture provided by our current science and is, therefore, the best we’ve got. Pretentious philosophical talk of ‘‘metaphysical’’ options can’t change the fact that naturalism is the only game in town since it is simply the totality of our theories in physics, chemistry, biology, neuroscience, geology and so on. Does Christian metaphysics provide a better account of quantum physics, cosmology or the structure of DNA?
Slezak is going to be accused of scientism or, at the very least, naturalism. The accommodationists will claim that the leap to naturalism is overstepping the limits of what science can or cannot claim. That's not true. Science teaches us that the scientific approach works and that most things have a naturalistic explanation. It follows that any claim of a valid a non-naturalistic explanation must have at least as much to recommend it or else it is nothing more than hand-waving.

If you look closely, you'll see that today's molecule is an unusual variant of a very common cell component. Your task for today is NOT to give this molecule a specific name but rather to describe it in general terms and identify three (3) ways in which it differs from the more common molecules. Finally, you have to tell us where these molecules are found.

UPDATE: This is a typical bacterial membrane lipid found in archaebacteria (Archaea) and in some gram-negative bacteria. It differs from the glycerophospholipids in eukaryotes and other bacteria in three ways. (1) The backbone molecule (a three carbon glycerol molecule) is sn-glycerol-1-phosphate, a stereoisomer of the more common backbone sn-glycerol-3-phosphate, found in other lipids. (2) The long fatty acid chains are attached to the glycerol moiety by an ether linkage, rather than an ester linkage. (3) The hydrocarbon chains of the fatty acid chains are composed of isoprenoid units methyl units. Today's winner is Raul A. Félix de Sousa (again).

David Klinghoffer noted recently that an anthropologist, Richard Leakey, and some lawyer named Jonathan H. Adler seem to be using different meanings of the word "evolution" [For Richard Leakey and So Many Other Darwin Advocates, Evolution Is a Word that Can Mean Anything]. It doesn't seem to matter to Klinghoffer that one of those men is a scientist and the other isn't.
Picking up on the point that evolution is a word that can mean anything, Joshua Youngkin1 adds his 2 cents [On the Useful Instability of the Word "Evolution"].
David's concern, I think, is that Darwinists use the term "evolution" in various and even conflicting ways in order to occasionally serve less-than-noble purposes. It's almost as if Darwinist usage of the term "evolution" is sometimes meant to keep skeptics and even the public guessing, as if to avoid a fair fight on the evidence about a stable, commonly understood set of propositions. Why would anyone want to do that?
The meanings of the word "evolution" can be found in evolutionary biology textbooks and at many places on the web. You can read two of my contributions at What Is Evolution? and Evolution Is a Fact and a Theory. It seems to me that many evolutionary biologists are making a very serious effort to define their terms.
Some of the IDiots actually get it as I pointed out a few weeks ago [All IDiots Believe in Evolution!]. That was in response to a posting by johnnyb who said ....
So what is one to do? Well, thankfully, our friends the evolutionists have given us a way out. In their zeal to claim consensus on the “fact of evolution,” they have had to steamroll together such a large diversity of opinion into the single term “evolution”, that the word “evolution” no longer has the grand meaning it used to. The only real meaning everyone can agree on is “change in allele frequency over time” – and that is a definition that literally everyone can agree with.
Apparently his fellow IDiots didn't get the memo.
It doesn't take a lot of effort to recognize what evolutionary biologists mean when they use the word "evolution." You have to be really stupid to imagine that they are deliberately using different meanings in in different contexts for the sole purpose of confusing the IDiots. As you can see, the IDiots are quite capable of confusing themselves without our help.
Speaking of deliberate obfuscation ... I wonder why they continue to refer to "Darwinists" when they've been told hundreds of times that this is not a synonym for "evolutionary biologists"? Is that for a "less-than-noble purpose" or is it just because the IDiots are stupid? I think we know the answer to that one.
I have some sympathy for bloggers who are ignorant but I don't like liars. However, the people I really hate are the hypocrites.
1. Joshua Youngkin is a lawyer who works for the Discovery Institute. He's probably an expert on the meaning of the word evolution.
Stephen Jay Gould died ten years ago on May 20, 2002. Last month there was a conference in Venice, Italy, that celebrated his legacy [Stephen J. Gould's Legacy: Nature, History, Society]. I wish I could have attended because all the main characters were there (Richard Lewontin, Niles Eldredge, Elisabeth Lloyd, and many more).
Ryan Gregory gave a talk on A Gouldian view of the genome and he has posted the video of his presentation (see below). I urge you to watch the whole thing but, if you only have a few minutes, then watch the beginning where Ryan describes the important lessons that Gould taught us.
I'll be going to this meeting next month. Let me know if you'll be there and we can arrange to meet for lunch, dinner, beer, or coffee. We'll definitely be doing a poutine run into Quebec and a walk to Byward Market to get beaver tails.
This is the year Canada celebrates it's victory over the USA in the war of 1812. You can thrill to the spectacle of the changing of the guards on Parliament Hill and see the fearsome redcoats up close. Americans (the losers) are welcome! :-)
Welcome to the site of the First Joint Congress on Evolutionary Biology (aka ‘Evolution 2012’), to be held in Ottawa, Canada’s capital city. This landmark event will bring together five of the world’s largest academic societies devoted to the study of ecology and evolutionary biology: the American Society of Naturalists (ASN), the Canadian Society for Ecology and Evolution (CSEE) the European Society for Evolutionary Biology (ESEB), the Society for the Study of Evolution (SSE), and the Society of Systematic Biologists (SSB). This event merges the traditional ‘Evolution’ meeting, the joint annual meeting of the ASN, SSE and SSB, with both its European and Canadian counterparts (the biennial ESEB congress and annual CSEE meeting). This will be the first time that these five societies have met together, creating a truly international event that spans the fields of ecology and evolution. The meeting will be the premier showcase in 2012 for the presentation and discussion among peers of the latest, leading-edge research in ecology and evolution, and will also be an important forum for outreach and education.
I'll also be attending two workshops on Friday July 6th.
EVO101
Science educators in the Ottawa area are invited to join evolutionary biologists and other science educators at the First Joint Congress on Evolutionary Biology for “EVO 101”, a one day workshop on evolution and using evolutionary data in the classroom. Come learn about exciting research in the field of evolution and attend sessions featuring hands-on activities designed to facilitate the integration of ecological and evolutionary data into your curriculum.
Workshop to include: Talks by scientists and educators and hands-on activities demonstrating effective and fun ways to teach evolution; FREE teaching resources and other give-aways for participants; an opportunity to meet and chat with professional evolutionary biologists who both study and teach evolution; attendance at the Gould Award Lecture, given by the recipient of the Stephen Jay Gould Prize, awarded annually by the Society for the Study of Evolution to recognize individuals whose sustained and exemplary efforts have advanced public understanding of evolutionary science and its importance in biology, education, and everyday life in the spirit of Stephen Jay Gould.
Communicating Science to Society
Whether you need to learn the basics or fine tune the dark art of science communication, this half day workshop is for you. Come for insider advice from a group of North America’s top science communicators. The session will open with evolutionary ecologist Tom Sherratt talking about his experience with the media and why he does it. The panellists will introduce an area of journalism and discuss their experiences with interviewing researchers. Then the panel discussion will expand on some of the challenges scientists face and the practical communication solutions. Finally a break-out session will allow for an interactive round table letting participants choose a topic of particular interest (how to give an interview, how to pitch a science book to a publisher, 101 for scientists using social media). The workshop will conclude with a networking session between fellow science communicators and the panellists. By the end, delegates can expect to have built a strategy as to how to effectively approach and handle different media opportunities (such as TV, radio, print & social media) and also leave with a handout of useful tips.
Hosts: Peter Calamai (Adjunct Research Professor, Carleton University School of Journalism and Communication; founding member of the Canadian Science Writers' Association) and Richard Webster (Science & Communications Officer for Row to the Pole and Biology Ph.D. candidate, Carleton University)
Speakers:
- Carl Zimmer (NYT columnist & author of A Planet of Viruses and many other best sellers)
- Penny Park (Producer of CBC’s Quirks & Quarks and Discovery Channel’s The Daily Planet. Now Executive Director of the Science Media Centre of Canada)
- Elizabeth Howell Ottawa Business Journal, freelance science journalist and social media expert
- Tim Lougheed Freelance science journalist
- Tom Sherratt Evolutionary ecologist, Carleton University
This second workshop is unusual because there's an actual scientist presenting! :-)
This is a rather unusual molecule but it's found in many species. You need to identify the molecule AND tell us why it was a significant discovery.

UPDATE: The molecule is pyrrolysine, an amino acid found in the proteins of some species of archaebacteria many species of bacteria. Pyrrolysine is made from lysyl-tRNA synthesized in the cytoplasm and attached to a specific pyrrolysyl-tRNA by a specific pyrrolysyl tRNA synthetase. Pyrrolysine is subsequently incorporated into protein during translation. It is inserted at a specific codon (UAG) and counts as the 23 amino acid. The 21st amino acid is N-formylmethionine and the 22nd amino acid is selenocysteine. Today's winner is Raul A. Félix de Sousa who responded before I remembered to turn on comment moderation so I had to delete his response.

"There's a sucker born every minute."

(frequently attributed to P.T. Barnum)For normal healthy people there's no evidence that vitamin supplements are necessary, or helpful, in any way [Good Food, Bad Food]. Megadoses of vitamins may be harmful [A bad week for the nutritional supplements industry].
So, why would anyone fork out good money for vitamin supplements?
Biochemistry instructors should make sure students understand the difference between science and pseudoscience. That's why I inserted boxes like this one in the latest version of my textbook.
Whatever happened to vitamin B4 and vitamin B8? They are never listed in the textbooks but you’ll often find them sold in stores that cater to the demand for supplements that might make you feel better and live longer.
Vitamin B4 was adenine, the base found in DNA and RNA.We now know that it’s not a vitamin. All species, including humans, can make copious quantities of adenine whenever it’s needed (Sections 18.1 and 18.2). Vitamin B8 was inositol, a precursor of several important lipids (Figure 8.16 and Section 9.12C). It’s no longer considered a vitamin.
If you know anyone who is paying money for vitamin B4 and B8 supplements then here’s your chance to be helpful. Tell them why they’re wasting their money.
This article, Shop locally, eat globally? , appeared in today's edition of our university bulletin. I thought it was worth posting a link because, unfortunately, many of my relatives, friends, and colleagues think you can support a large city by only eating food grown within one hundred miles (161 kilometers).
Pierre Desrochers knows how to serve up controversy. When an acquaintance mentions she follows a 100-mile diet to help the environment, Desrochers calmly asks how much energy it takes to heat an Ontario greenhouse.
When a colleague lauds local food as more nutritious than products shipped thousands of miles, Desrochers politely points out that the diet of a 19th-century German peasant consisted of lentils and peas.
Now, the University of Toronto Mississauga geography professor has published a controversial new book that goes beyond polite mealtime conversation and pits what Desrochers calls the “romanticism” of local eating, or locavorism, against the realities of a global food-supply chain.
Desrochers is the co-author of The Locavore’s Dilemma: In Praise of the 10,000-mile Diet, in which he argues that we should stop obsessing about how many miles our food has travelled to get to our dinner plate.
“Three centuries ago most people were eating local food,” Desrochers says. “Why do we think the world moved away from that? There are significant benefits—particularly, environmental and economical—in collaborating to produce food in the best geographic locations.”
I just heard from Dave Greig that Richard Harter died over a month ago [Richard Harter 1935 - 2012]. He was a long time contributor to talk.origins having been there since it was called net.origins in the early 1980s. Richard was a staunch defender of science and evolution and a vocal opponent of stupidity (aka creationism). Here's how he describes the phenomenon that is talk.origns [Evolution, Creationism, and Crackpots].
I discovered the usenet news groups circa 1983. In those days there was no big 8 hierarchy; everything was net.this and net.that. One of the hot groups was net.origins, now talk.origins, the designated dumping grounds for creationism/evolution flame fests.
Some usenet newsgroups are models of decorum, where specialists in sundry topics urbanely discuss their specialties. Some are havens of nattering wherein recipes and small talk are exchanged. Such newsgroups represent usenet at its best as a civilized expression of the electronic personal free press. How boring.
There are newsgroups which are open cockpits wherein all and sundry engage in electonic eye-gouging, leaving bodies scattered about the floor, bodies which miraculously arise to gouge and rabbit punch in return. Much more entertaining. Unfortunately such entertainments pall after a while. The same things are said by the same people endlessly. When one flamer departs he or she is replaced by a clone, another mindless dweeb screaming invective into the electronic night air. There is no content, merely an exchange of prejudices and emotion.
The talk.origins group is, to my taste, a happy combination of meat and sauce. To be sure there are no end of flames. However there is much content also. It all has to do with the subject matter. Talk.origins is supposed to be the arena where creationism and evolution are debated. That happens. However it is a happy hunting grounds for cranks and crackpots who come to be told that they are idiots. They revel in it for, finally, someone is listening to them.
The nifty thing about talk.origins is that you can get a real education by reading the group -- the crackpots are not only told that they are idiots, people cite chapter and verse to show where they are in error. Biologists, archaeologists, paleontologists, and the like post there. There is also a good deal of offbeat humor. For your delectation I have prepared a potpourri of essays and materials drawn from talk.origins.
Richard was born in South Dakota and he moved back there in 2000. He never stopped reminding us that South Dakota actually exists and people actually live there. He died of complications from myelodysplastic syndrome (MDS) [Why couldn't I have something simple, like pneumonia].
There's lots more where that came from. Check out Richard Harter's World while it's still active. I especially like his detailed analysis of one of the most difficult problems in all of science: The Seat Stays Up. His summary of everything related to Piltdown Man is a classic.1
The motto on his web page is appropriate ...
I don't worry about dying.
It's not going to happen in my lifetime.
UPDATE: talk.origins remembers Richard Harter
UPDATE: I'm told that Richard's website will be preserved at Richard Harter's World.

Michael Ruse wrote a book called Science and Spirituality: Making Room for Faith in the Age of Science (2010). It's a defense of accommodationism—the position of atheists who maintain that science and religion are compatible because they are different ways of knowing. Ruse is one of the main proponents of Methodological Naturalism, which postulates that science is restricted, or limited, to investigations of the natural world. Since religion deals, by definition, with the supernatural world, it falls outside the domain of science and is, therefore, compatible with science. This leads Ruse to define several criteria of Christianity that are immune to scientific investigation [The Essence of Christianity].
David Klinghoffer noted recently that an anthropologist, Richard Leakey, and some lawyer named Jonathan H. Adler seem to be using different meanings of the word "evolution" [For Richard Leakey and So Many Other Darwin Advocates, Evolution Is a Word that Can Mean Anything]. It doesn't seem to matter to Klinghoffer that one of those men is a scientist and the other isn't.
Stephen Jay Gould died ten years ago on May 20, 2002. Last month there was a conference in Venice, Italy, that celebrated his legacy [Stephen J. Gould's Legacy: Nature, History, Society]. I wish I could have attended because all the main characters were there (Richard Lewontin, Niles Eldredge, Elisabeth Lloyd, and many more). 
I'll be going to this meeting next month. Let me know if you'll be there and we can arrange to meet for lunch, dinner, beer, or coffee. We'll definitely be doing a poutine run into Quebec and a walk to Byward Market to get beaver tails.
This is a rather unusual molecule but it's found in many species. You need to identify the molecule AND tell us why it was a significant discovery.
