Monday's Molecule #203

The last Monday's Molecule was medium chain acyl-CoA dehydrogenase (MCAD) (PDB 2AIT). Nobody got the right answer [Monday's Molecule #202].

Today's molecule is very important for humans. You need to supply the common name AND a more official IUPAC name that identifies the configuration of the bonds. You also need to briefly explain why this molecule is important in humans.

Email your answers to me at: Monday's Molecule #202. I'll hold off posting your answers 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.

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 email message.)

Dawkins and Krauss on CNN

Here's a CNN interview with Richard Dawkins and Lawrence Krauss. It was recorded this morning. It's very unfortunate that the reporter (Poppy Harlow) injects her own views on religion but at least they serve to illustrate the prejudice against unbelievers.

There are quite a few CNN reporters who broadcast their Christian views at every opportunity. They just don't get it.

DNA: Nature Celebrates Ignorance

Some freelance science writer named Philip Ball has published an article in the April 25, 2013 issue of Nature: Celebrate the Unknowns.

The main premise of the article is revealed in the short blurb under the title: "On the 60th anniversary of the double helix, we should admit that we don't fully understand how evolution works at the molecular level, suggests Philip Ball."

What nonsense! We understand a great deal about how evolution works at the molecular level. Perhaps Philip Ball meant to say that we don't understand the historical details of how a particular genome evolved, but even that's misleading.

I've commented before on articles written by Philip Ball. In the past, he appeared to be in competition with Elizabeth Pennisi of Science for some kind of award for misunderstanding the human genome.

Keith Yamamoto on Taking Risks

Here (below) is my old friend, Keith Yamamoto, talking about taking risks in science. Keith and I were graduate students in Bruce Alberts' lab over 40 years ago. That's him on the left in the photo. I'm the one looking up and the third former graduate student is Glenn Herrick.

Keith and I learned a lot about science from our former mentor. I learned a lot from Keith; for example, he taught me that it is more important to print in your notebook than to use cursive writing. I've been printing ever since.

Keith also helped me learn that it's sometimes important to fight for a cause even if you know you're going to lose. (He was county coordinator for the George McGovern presidential campaign in 1972.¹)

The take-home message in this video is that good scientists need to take risks. It's one of those "motherhood" kinds of statements that every scientist will support but few actually do it. It saddens me to say that today we live in a culture where mundane, data-collecting, science is often more successful than risky science (e.g. ENCODE). Risk entails the possibility of failure and even though you might learn from failure [Bruce Alberts on Learning from Failure], it won't do you much good if you don't get a job or you lose your grant.

So I disagree with Keith when he says that we should encourage risk-taking in young scientists. Some of the best scientists I know took risks and and the work didn't pan out. They couldn't get any papers published and they lost their grants. They were cut out of the system in favor of scientists who could guarantee successful results in their grant proposals. The fact that the results were boring and did nothing to advance our knowledge, wasn't important.

I advise young scientists, post-docs, and graduate students to always have a "safe" project. Don't put all your eggs in the risky science basket. It makes me sad to give that advice.

Bruce Alberts on Learning from Failure

Here's a short talk from my thesis supervisor on learning from failure. He tells the story of how he failed his Ph.D. oral and how he almost gave up writing his textbook.

I was a gradate student in his Princeton lab from 1969-1974. The most important lesson I learned from Bruce was the importance of knowledge and context. He taught a graduate course called "Macromolecules" where he explained both the basic chemistry and the basic biology. The lesson was clear. You can't do good science unless you see the big picture and understand the fundamentals of your discipline. He reminded us almost every day. As he says in the video ...

Theoretical biology is much more important than my generation had imagined. We were misled by the striking success of the 1953 Watson-Crick DNA model.

I also agree with another comment he makes in the video ...

Both book writing and teaching are really important for creative science, I believe.

Bruce also encouraged us to explore topics outside of our research project. This included Jacques Monod's book "Chance and Necessity: Essay on the Natural Philosophy of Modern Biology" and the writings of the best theoretical biologists of the time. We were encouraged to get involved in politics and society. It was a time of protest and revolution, and scientists had a role to play.

PZ's Wonderful Exam Question

PZ Myers has just given his students a take-home exam. Here's one of the questions [It’s another exam day! ] ...

Question 1: One of Sarah Palin’s notorious gaffes was her dismissal of “fruit fly research” — she thought it was absurd that the government actually funded science on flies. How would you explain to a congressman that basic research is important? I’m going to put two constraints on your answer: 1) It has to be comprehensible to Michele Bachmann, and 2) don’t take the shortcut of promising that which you may not deliver. That is, no “maybe it will cure cancer!” claims, but focus instead on why we should appreciate deeper knowledge of biology.

That first restriction is going to make answering the question a real challenge 'cause you have to take into account the mentality of someone who is not just scientifically illiterate but scientifically anti-literate.

Nevertheless, this is exactly the sort of thing you want your science graduates to know.

Is It Illegal to Teach Intelligent Design Creationism in American Universities?

Jerry Coyne has discovered that a course at Ball State University (Indiana) teaches science from a viewpoint that's sympathetic to Intelligent Design Creationism [“Science” course at Ball State University sneaks in religion]. It looks like a really bad course and I'm glad that it's getting a lot of negative publicity. It looks like the instructor is advocating Intelligent Design Creationism.

I defend the right of a tenured professor to teach whatever he/she believes to be true no matter how stupid it seems to the rest of us.¹ I'm troubled by the fact that some people are calling for the instructor's dismissal and writing letters to the chair of his department. We really don't want to go down that path, do we? Academic freedom is important and it's especially important to defend it when a professor is pushing a view that we disagree with.

But that's not the only troubling thing about Jerry Coyne's post and the comments it has stimulated. Jerry thinks that it is unconstitutional (i.e. illegal) for a university professor to be advocating religion in a publicly-funded university. He says,

Ball State University, in Muncie, Indiana, is a public university (i.e., part of the state university system). As such, it must abide by the First Amendment to the U.S. Constitution, which has been interpreted as disallowing religious viewpoints (or religiously based theories) in public-school science classes. It is of course kosher to teach courses on the history of religion, or on the relationship between science and religion, but those must not pretend to be “science” courses, and must present balanced views—they can’t push a particular religious viewpoint.

But it’s come to my attention that a science course at Ball State University—actually two courses, because it seems to be cross-listed—is little more than a course in accommodationism and Christian religion, with very little science. It’s my firm opinion that teaching this course at a state university not only violates the First Amendment, but cheats the students by subjecting them to religious proselytizing when they’re trying to learn science.

Is he right? Does the US Constitution really specify that you can't advocate a religious viewpoint in a university classroom?

That's very scary. It probably means that you can't criticize religion either. Does this mean that there's going to be a bevy of lawyers on both sides of the issue examining the content of university courses all across America?

UPDATE:
PZ Myers: I have to disagree with Jerry Coyne

Sixty Years Ago Today: April 25, 1953

Sixty years ago on this day, Nature published three back-to-back papers on the structure of DNA. It was a momentous day for science. Here's how Horace Judson describes it in The Eighth Day of Creations (pp. 154-155)...

The letter to Nature appeared in the April 25 issue. [It was submitted on April 2—LAM] To those of its readers who were close to the questions, and who had not already heard the news, the letter must come off like a string of depth charges in a column sea. "We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological interest," the letter began; at the end, "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material." That last sentence has been called one of the most coy statements in the literature of science. According to Watson, Crick wrote it. Wilkins's paper followed, signed also by two of his associates at King's College, A. R. Stokes and H. R. Wilson. It was a restatement of helical diffraction theory, and sprang to life and significance only in the last paragraphs, where Wilkins briefly reported that his x-ray diffraction studies of intact sperm heads and bacteriophage—both, of course, containing a high proportion of DNA—gave patterns that suggested that DNA in living creatures has a helical structure similar to the model just proposed. The note by Franklin and Gosling came next. It was a revision and extension of their draft from the middle of March, in the light of the model. It presented the crucial diffraction photo structure B and analyze that and the other experimental evidence to show—with curt authority—that Franklin's data were compatible with Watson and Crick's structure.

The three papers are ....

Watson, J.D. and Crick, F.H.C. (1953)A Structure for Deoxyribose Nucleic Acid. Nature 171:737-738. [See: The Watson & Crick Nature Paper (1953)] [PDF]

"We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological interest."

Wilins, M.H.F., Stokes, A.R., and Wilson, H.R. (1953) Molecular Structure of Deoxypentose Nucleic Acids. Nature 171:738-740. [See: The Wilkins, Stokes and Wilson Nature paper (1953)] [PDF]

"The biological significance of a two-chain nucleic acid unit has been noted (see preceding communication). The evidence that the helical structure discussed above does, in fact, exist in intact biological systems is briefly as follows: ..."

Franklin, R. and Gosling, R.G. (1953) Molecular Configuration in Sodium Thymonucleate. Nature 171:740-741. [See: The Franklin & Gosling Nature paper (1953)] [PDF]

"Thus, while we do not attempt to offer a complete interpretation of the fibre-diagram of structure B, we may state the following conclusions. The structure is probably helical. The phosphate groups lie on the outside of the structural unit, on a helix of diameter about 20 Å. The structural unit probably consists of two co-axial molecules which are not equally spaced along the fiber axis, their mutual displacement being such as to account for the variation of observed intensities of the innermost maxima on the layer lines; if one molecule is displaced from the other by about three-eights of the fibre-axis period, this would account for the absence of the fourth layer line maxima and the weakness of the sixth. Thus, our general ideas are not inconsistent with the model proposed by Watson and crick in the preceding communication."

Nothing in Biochemistry Makes Sense Except in the Light of Evolution

The title of this post is a slight paraphrasing of Theodosius Dobzhansky's famous saying, "Nothing in Biology Makes Sense Except in the Light of Evolution. That was the title of an article he published in American Biology Teacher and that's significant since the main point was to convince teachers that evolution is important.

What applies to biology also applies to biochemistry. Evolution should come up in many places in a typical biochemistry course. The most obvious place is when we teach comparisons of nucleotide and amino acids sequences and the construction of phylogenetic trees. Students have to know the underling concept behind these comparisons. The have to know why some sequences are conserved (negative selection) and why some sequences are variable (fixation of neutral alleles by random genetic drift).

But this isn't the only place where evolution is important. How can you explain why humans need vitamin C and "essential" amino acids without mentioning evolution? How can you teach biochemistry without covering the evolution of biochemical pathways? How do you explain the existence of a complex process like the membrane-bound photosynthesis complexes in chloroplasts without showing how it evolved from simple bacterial examples? Who teaches the information flow section of the course without starting with E. coli and working toward the more complex eukaryotic examples? How do you explain why animals need glucose when most species don't need an external supply of complex carbohydrate? How do you explain why gluconeogenesis is a more primitive pathway than glycolysis? Why are comparative genome studies important in working out metabolic networks? Why does "homology modeling" work?

The American Society for Biochemistry and Molecular Biology (ASBMB) is trying to set up a certification scheme for biochemistry programs in America. The idea is that universities and colleges that meet certain standards would receive a stamp of approval from ASBMB. There would be a nation-wide exam for graduating students and if they pass the exam they get a sort of "certification" that proves they have the minimum skills and knowledge to take jobs that require these skills.

The trick is to define the common skills and knowledge that are needed. I attended two sessions at EB2013 where these criteria were discussed. One was a presentation by the committee in charge followed by some discussion: "ASBMS Certification Program for Bachelor's Degrees in Biochemistry Molecular Biology and Related Majors." The questions in this session were focused on how to get certified and not on what was in the proposal.

The other session was "Promoting Concepts-Driven Teaching Strategies in BMB Through Concept Assessments" but, as it turned out, there was very little chance to discuss the concepts that were being assessed.

You can read the current draft proposal by clicking on the link at ASBMB Degree Certification Program in Biochemistry and Molecular Biology. You might be interested in finding out what a department needs to do in order to be certified.

I'm more interested in what biochemists have to teach. Here's the relevant section ...

Core Concepts and Learning Objectives

An ASBMB-recognized program should be able to relate each element of its BMB curriculum to one or more of the core concepts listed below and their related learning objectives (For reasons of space, sample learning objectives are provided in Appendices II – V):

1. Energy is Required by and Transformed in Biological Systems.
2. Macromolecular Structure Determines Function and Regulation
3. Information Storage and Flow Are Dynamic and Interactive.
4. Discovery Requires Objective Measurement, Quantitative Analysis, & Clear Communication.

The curriculum should present these core concepts in a manner that illustrates the pervasive role that Evolution plays in shaping the form and function of all biological molecules and organisms.

That last sentence is new to me. I've never seen it on any of the slides shown at either of the meetings I attended (EB2012 and EB2013).

It's a welcome addition. But, since most biochemistry courses in America are taught out of Chemistry Departments, I wonder if this will make certification more difficult.

Finally, I can't help but insert a plug for my book. It's the only biochemistry textbook that presents the subject from an evolutionary perspective and it's certainly the only textbook where the pervasive role of evolution is emphasized in every chapter.

The next step will be to help the organizing committee refine and upgrade the "Learning Objectives" for each of the core concepts. These are given in four appendices in the draft document.

Measuring Teaching Effectiveness

Having just sat through many talks and read many posters on how to measure what we teach, I'm struck by the overwhelming emphasis on how to measure what biochemists are teaching and the incredible lack of interest in evaluating whether we are teaching the right things.

That's why this image resonated with me. Arthur L. Costa is a retired Professor of Education at the California State University, Sacramento.

Better Biochemistry at EB2013

I've been talking to a lot of people here at EB2013 in Boston. One of the main topics of conversation is education in biochemistry and molecular biology. Another is blogs and social media. Some of these new friends are going to be looking at Sandwalk so I've prepared a short list of links on teaching biochemistry.

By
K.A. Worp 

The only aim of this survey is to provide a collection of editions of mummy labels from Graeco-Roman Egypt inscribed with texts in Greek and / or Demotic (including a few texts in late- Hieratic). These short texts (almost 3000 items, mostly written on wood) are dispersed now all over the world and incorporated into a great many collections; in course of time many (but not yet all) of them have been published in a wide variety of editions. The survey1 consists of two main sections, viz.:─ (I.a) A list of Greek and bilingual texts published in various major special editions of a collection (in particular T.BM Arlt and T.Mom.Louvre), in other special corpora of such mummy labels (S.P. Vleeming’s Short Texts, vol. 2, and B. Boyaval’s Corpus des Étiquettes de Momie Grecques [below: C.E.M.G.) or in various other text editions of papyri (in particular the Greek Sammelbuch) and in various journals. The list was compiled from data collected in Trismegistos (see ) and the HGV (see ) while searching in these data bases for ‘material = wood’.

─ (I.b) A list of mummy label texts in Demotic and late Hieratic compiled from
─ (I.b) A list of mummy label texts in Demotic and late Hieratic compiled from Trismegistos / DAHT (see ).
─ (II) A list of locations of collections of various mummy labels listed in the first section. The list is arranged alphabetically according to modern toponym. ─ (II) A list of locations of collections of various mummy labels listed in the first section.

Homère, Iliade, XVI, 45–56 Un nouveau papyrus homérique conservé à la Bibliothèque nationale de France: P.ParisBnF inv. Suppl. gr. 1385.1 (4) Pages 193–200, 

—Abstract

This article presents an edition of an unpublished Homeric fragment in Paris containing Homer, Iliad, XVI, 45-56. Observations on its content, form and layout, and an investigation of the other papyri of Iliad XVI show that the Paris fragment belonged to the same family as P.Harr. I 122.

—Abstract

P.Erl. 5 (inv. 3), recto (LDAB 1567 = MP3 1169) contains a paraphrase of part of the argument between Zeus and Hera at the end of Book I of the Iliad (v. 528-48). It is characterized by its similarity to the ‘grammatical’ rather than ‘rhetorical’ type of paraphrase, although it cannot be classified as purely grammatical either.

—Abstract

The word τέθριππον in l. 11 of this commentary on part of Book 12 of the Iliad (MP3 1194.01; 5th/6th century AD) allows a reconstruction of the meaning of the annotation, and of the related text, that fits well with the corresponding scholium exegeticum 12.91-92, and provides further confirmation of the strong affinity between the commentary and this class of medieval scholia.

Zur Datierung von Euripides’ Μήδεια-Dramen

—Abstract

Aristophanes of Byzantium’s hypothesis of the preserved Mήδεια of Euripides awards Sophocles second place in 431 BC, but in the new report of P.Oxy. 5093 Sophocles was the winner with Τηρεύς. This difference is explicable if the known hypothesis belongs to the first Μήδεια. If that is the case, the preserved Μήδεια must have been performed later than 431.

What Is a τρυϲινον? A Fresh Look at P.Oxy. XIV 1674

—Abstract

This article presents a new transcription of the word τρυϲινον in P.Oxy. XIV 1674.5 based on a recent autopsy, a word which Grenfell and Hunt left untranslated in their edition due to its being unattested in the Greek language. The word is most likely a misspelling of a common Greek word meaning “fire drill”, and would thus fit well within the agricultural context of the letter. An image of P.Oxy. XIV 1674 is published here for the first time.

Judging the Quality of MOOCs

Another journalist has written about Massive Open Online Courses (MOOCs). This one is in The New York Times: Two Cheers for Web U!.

Most of these articles about MOOCs are not very good but this one is different. The author expresses some skepticism and hit the nail on the head when he says ...

But the first thing I learned? When it comes to Massive Open Online Courses, like those offered by Coursera, Udacity and edX, you can forget about the Socratic method.

The professor is, in most cases, out of students’ reach, only slightly more accessible than the pope or Thomas Pynchon.

But that's not what I want to talk about today. I want to discuss the quality of these courses and how you might go about judging whether they are truly teaching the subject correctly.

Here's the problem. Too many people, like A. J. Jacobs, the author of today's article, assume that because the lecturer is famous or from a "top" school, the material must be accurate and up-to-date. As A. J. Jacobs puts it ...

On the other hand, how can I really complain? I’m getting Ivy League (or Ivy League equivalent) wisdom free....

With the exception of a couple of clunkers — my plodding nutrition professor might want to drink more organic coffee before class — most of my MOOC teachers were impressive: knowledgeable, organized and well respected in their field.

Students are not in a position to judge whether a professor is "knowledgeable" about the material being covered in a course. In the case of MOOCs, many students just assume that because the professor is from an Ivy League school then he/she knows how to teach an introductory course properly.

That's a very bad assumption as I've shown when I examined the biochemistry material being taught in the MIT courses Where Are the Best University Teachers?. Same is true for the courses at the Khan Academy.

I'm currently in Boston at EB2013 where I'm hanging out with biochemistry and molecular biology teachers and textbook authors. Many of these experts are not household names but they are the experts in their field, which is teaching. If you really want accurate information about the fundamental principles and concepts in biochemistry and molecular biology then you should take the courses they teach. You'll get a far better education than if you listen to professors from big-name research intensive-universities.

The recent ENCODE publicity disaster is just one example of the fact that top-notch researchers don't necessarily understand the fundamentals of subjects that are just outside of their own area of expertise.

Let's try and put a stop to this myth that the best teachers are professors from Ivy League schools. There's very little evidence to support that myth, especially in fields that I'm familiar with: evolution, biochemistry, and molecular biology,

Biology in Boston

I arrived in Boston, got settled in my hotel, and registered for Exeperimental Biology 2013.

My society is the American Society for Biochemistry and Molecular Biology (ASBMB). The main event tonight was the Herbert Tabor Research Award Lecture and the two awardees were ...

Ulrich Hartl Molecular chaperones in cellular protein folding mechanisms and pathways.

Arthur Horwich Chaperonin-induced protein folding.

This was followed by a reception featuring posters on outreach activity. It was fun talking to the poster presenters and seeing different ways of communicating science.


The photo below was taken from the convention center looking north at the World Trade Center. My hotel is the farthest one on the right of the main road going over the bridge. All the flags are at half-mast.

Coelacanths Evolve More Slowly?

I don't have a lot of time today (I leave for Boston tomorrow) but I can't let this pass.

The complete draft genome of the African coelacanth, Latimeria chalumnae has just been published in Nature (Amemiya et al. 2013). Ceolacanths have long been regarded as "living fossils," a term that persists even though the data have been disputed ever since the first fish were identified 75 years ago. I couldn't believe what I was reading when I saw the press release from the Broad Institute in Boston [Coelacanth genome surfaces]. The author, Haley Bridger of Broad Communications, says ...

An international team of researchers has decoded the genome of a creature whose evolutionary history is both enigmatic and illuminating: the African coelacanth. A sea-cave dwelling, five-foot long fish with limb-like fins, the coelacanth was once thought to be extinct. A living coelacanth was discovered off the African coast in 1938, and since then, questions about these ancient-looking fish – popularly known as “living fossils” – have loomed large. Coelacanths today closely resemble the fossilized skeletons of their more than 300-million-year-old ancestors. Its genome confirms what many researchers had long suspected: genes in coelacanths are evolving more slowly than in other organisms.

“We found that the genes overall are evolving significantly slower than in every other fish and land vertebrate that we looked at,” said Jessica Alföldi, a research scientist at the Broad Institute and co-first author of a paper on the coelacanth genome, which appears in Nature this week. “This is the first time that we’ve had a big enough gene set to really see that.”

Researchers hypothesize that this slow rate of change may be because coelacanths simply have not needed to change: they live primarily off of the Eastern African coast (a second coelacanth species lives off the coast of Indonesia), at ocean depths where relatively little has changed over the millennia.

This can't be right, I said to myself. Let's check out the actual paper.

Unfortunately, it was right. Here's the figure and here's what the authors say in the results section of the paper.

The morphological resemblance of the modern coelacanth to its fossil ancestors has resulted in it being nicknamed ‘the living fossil.’ This invites the question of whether the genome of the coelacanth is as slowly evolving as its outward appearance suggests. Earlier work showed that a few gene families, such as Hox and protocadherins, have comparatively slower protein-coding evolution in coelacanth than in other vertebrate lineages. To address the question, we compared several features of the coelacanth genome to those of other vertebrate genomes.

Protein-coding gene evolution was examined using the phylogenomics data set described above (251 concatenated proteins) (Fig. 1). Pair-wise distances between taxa were calculated from the branch lengths of the tree using the two-cluster test proposed previously to test for equality of average substitution rates. Then, for each of the following species and species clusters (coelacanth, lungfish, chicken and mammals), we ascertained their respective mean distance to an outgroup consisting of three cartilaginous fishes (elephant shark, little skate and spotted catshark). Finally, we tested whether there was any significant difference in the distance to the outgroup of cartilaginous fish for every pair of species and species clusters, using a Z statistic. When these distances to the outgroup of cartilaginous fish were compared, we found that the coelacanth proteins that were tested were significantly more slowly evolving (0.890 substitutions per site) than the lungfish (1.05 substitutions per site), chicken (1.09 substitutions per site) and mammalian (1.21 substitutions per site) orthologues (P < 10−6 in all cases) (Supplementary Data 5). In addition, as can be seen in Fig. 1, the substitution rate in coelacanth is approximately half that in tetrapods since the two lineages diverged. A Tajima’s relative rate test confirmed the coelacanth’s significantly slower rate of protein evolution (P < 10⁻²⁰)

The authors make it clear in the discussion that they think of molecular evolution of amino acid sequences only in terms of adaptation.

Since its discovery, the coelacanth has been referred to as a ‘living fossil’, owing to its morphological similarities to its fossil ancestors. However, questions have remained as to whether it is indeed evolving slowly, as morphological stasis does not necessarily imply genomic stasis. In this study, we have confirmed that the protein-coding genes of L. chalumnae show a decreased substitution rate compared to those of other sequenced vertebrates, even though its genome as a whole does not show evidence of low genome plasticity. The reason for this lower substitution rate is still unknown, although a static habitat and a lack of predation over evolutionary timescales could be contributing factors to a lower need for adaptation. A closer examination of gene families that show either unusually high or low levels of directional selection indicative of adaptation in the coelacanth may provide information on which selective pressures acted, and which pressures did not act, to shape this evolutionary relict.

This extraordinary claim flies in the face of everything we know about molecular evolution. Preliminary data from some of these same authors was criticized by Casane and Laurenti1 (2013) earlier this year. I'll quote what they said and leave it up to Sandwalk readers to draw their own conclusions.

Transposing the concept of ‘living fossil’ to the genomic level has led to the hypothesis of genetic stasis (or at least to the idea of a reduced molecular evolutionary rate) that is in sharp contrast with the principles of evolutionary genetics. Genomes change continuously under the combined effects of various mutational processes, that produce new variants, and genetic drift and selection, that eliminates or fixes them in populations. In other terms, the only possibility for genomes to replicate without change implies at least one of the two following conditions: (i) new variants do not appear (i.e. no mutations), and (ii) new variants are systematically eliminated by selection (i.e. no genetic drift and very powerful selection against new variants). Of course we can consider a less extreme case, i.e. a reduced evolutionary rate of the genome, but this still implies a lower mutation rate and/or stronger selection against new variants than observed in other species.

The coelacanth data make no sense. You should be very skeptical.

You should also wonder about the kind of people that Nature asks to review their papers. Reviewers may not be inclined to challenge the data but they should challenge the conclusions and they should ask the authors to address the fact that their interpretation is inconsistent with the modern evolutionary theory.

One other thing, if you look through the names of the authors, you will see several people who should know better than to attach their name to a paper like this. What's going on?

What to Do with Old Conference Name Tags?

Ryan Gregory asked what he should do with his old conference name tags (on Facebook).

You hang them on your office door, of course. What else would you do with them?

Sometimes I wonder about those young professors. You have to help them with every little problem that comes up. Being a mentor is such a drag.

Darwin Doubters Want to Have their Cake and Eat it too

The phrase "to have your cake and eat it too" means that you can't have it both ways or "shouldn't try to have two incompatible things" [You can't have your cake and eat it].

The Intelligent Design Creationists are giving us a good example of just what this means. They have a new book coming out called "Darwin's Doubt." It's to be published by the religious arm of HarperCollins. The book will be available in a few months in the USA so the IDiots are ramping up the hype in preparation. We are told that this book, just like several previous books from the Discovery Institute, will definitively refute evolution and demonstrate the truth of Intelligent Design Creationism.

Here's how casey Luskin put it a few days ago [Three (or Four) Reasons Everyone Should Read Darwin's Doubt].

When published, Darwin's Doubt will be the single most up-to-date rebuttal to neo-Darwinian theory from the ID-paradigm. In this regard, one exciting element of Darwin's Doubt is that Meyer reviews much of the peer-reviewed research that's been published by the ID research community over the last few years, and highlights how ID proponents are doing relevant research answering key questions that show Darwinian evolution isn't up to the task of generating new functional information.

Here's how the strategy works. The IDiots are arguing the merits of Meyer's new book on the leading creationist blogs. They are generating lots of publicity and convincing their followers that the book is going to be a devastating rebuttal of "Darwinism." None of their followers have read the book but that doesn't matter. They won't have to.

How are scientist supposed to respond? None of us have read the book so we can't (yet) show that it is just more of the same old propaganda that we've seen before. What we can say is that we are very skeptical of the claims being made and we think it is disingenuous to promote those claims when we can't examine the "evidence." We can confidently speculate about what Stephen Meyer is going to say because he has a history and because he gives away some of his arguments in the publicity surrounding the book. The IDiots only sing one note and there's a very high probability that this isn't going to change.

That's exactly what Jerry Coyne said in his post: A (formerly) reputable publisher sells out to creationists. He puts it very nicely—and undoubtedly accurately— when he says, "But creationist Stephen Meyer, from the Discovery Institute, has apparently wrapped up the story. He’s hit upon the real reason for the Cambrian explosion: it’s intelligent design! Yes, baby Jesus made the phyla!"

Does anyone with an IQ over 50 think Coyne's prediction is wrong?

You know what's coming because we've seen it all before with the pre-publication hype for "The Myth of Junk DNA." "Science of Human Origins," and "Signature in the Cell." This time it's David Klinghoffer who is the designated whiner [Current Trends in Darwinian Book-Reviewing].

With a pub date of June 18, naturally no books are available. (Though you can preorder at a nice discount, for now, better than Amazon, over at DarwinsDoubt.com.) Nevertheless, at Why Evolution Is True, University of Chicago biologist Jerry Coyne assumes he knows what will be in the book. His absurd summary: "Yes, baby Jesus made the phyla!"

...

Darwinists have a curious way of responding to serious scientific and intellectual challenges to their beliefs. And it's getting more curious, isn't it? It's sort of evolving. If they had answers to ID's challenges, surely they would wait till they read the book, then accurately characterize what it says, and then tell us why Steve Meyer is wrong. But so far, and wasting no time, they have signaled in this strange prophylactic manner their unwillingness to do so.

The solution is obvious to everyone but the IDiots. Don't make outlandish claims about what's in a book until it's published and everyone can check for themselves. It you speculate about what the book is going to say then don't be surprised if others do as well.

You can't have your cake and eat it too.

Educating an Intelligent Design Creationist: Evidence for Junk

I'm replying to a post by andyjones (More and more) Function, the evolution-free gospel of ENCODE. That was the fourth post in an exchange between me and him. In response to his latest post, I'm working my way through five issues that Intelligent Design Creationists need to understand. So far, we've covered four of them.

Educating an Intelligent Design Creationist: Introduction
Educating an Intelligent Design Creationist: Pervasive Transcription
Educating an Intelligent Design Creationist: Rare Transcripts
Educating an Intelligent Design Creationist: The Specificity of DNA Binding Proteins
Educating an Intelligent Design Creationist: The Meaning of Darwinism

Intelligent Design Creationists have difficulty understanding the arguments for junk DNA and the evidence that supports those arguments. We try to explain the genetic load argument but it doesn't seem to penetrate. We try to explain that half of our genome is composed of defective transposons and viruses—often fragments of the intact genes. This doesn't phase them. And no matter how many times we describe the "C-value Paradox" and why junk DNA resolves the paradox, that evidence is ignored. We patiently describe the megabase pair deletions of the mouse genome and why this is evidence of junk. We teach them about copy number variation in the human genome and why DNA fingerprinting works. We show them examples of deletions and insertions in the genomes of different individuals telling them that these seem to have no effect as far as we know. We take time to explain modern evolutionary theory and why it is consistent with junk DNA. Finally, we describe our detailed textbook understanding of transcription and DNA binding proteins and they don't listen.

Andyjones says,

The fact that some very good scientists have not found functions for all of the genome does not negate the many functions they have found so far, for many classes of genetic element, including those commonly classed as ‘junk’. And they are still working. Part of the problem is this: if a layperson were to take apart a microchip, would he be able to discern the function of all the parts at the first attempt? Probably not. The problem is not lack of intelligence, but an early lack of understanding of the principles by which the thing is built. As soon as he understands a particular design principle, suddenly huge areas of the chip will be comprehensible to him. I humbly suggest that we have a number of such minor revolutions ahead of us in molecular biology. We are making great strides, but we do not yet understand all the principles of the transcriptome never mind the whole interactome. Perhaps there is more to learn about binding sites for RNAP? Or take pseudogenes: they have already been found to function in some cases as regulators, through their RNA transcripts interacting with real gene RNA transcripts. Then, alternative splicing is only partly understood. Who knows what other mechanisms operate at the RNA level? If you can’t imagine the function yet, it can be pretty hard to find it. But if one asserts there is no function (for example for rare transcripts) like Larry does, it will be even harder to find it.

This is a common theme among the Intelligent Design Creationists and, in fairness, among many molecular biologists. They think that junk DNA is simply an expression of ignorance. They ignore everything we tell them. They think that just because they don't understand something then nobody else does either.

In spite of what our opponents say, we actually have a pretty good understanding of the principles behind how a genome is built. Population genetics tells us that it ain't designed.

When I assert that rare transcripts probably have no function I'm not just talking through my hat and I'm not the only biochemist who says that. When I say that one million little bits and pieces of Alu SINES are very unlikely to have a function, that's not just idle speculation. When the ENCODE workers try to tell me that most of the genome is a huge web of 636,336 regulatory sequences, I can test this claim against the vast amount of information that we already know about genomes and transcriptional regulation and declare that this makes no sense. These are not arguments from ignorance.

Opponents of junk DNA are never going to be credible unless they tell us why the genetic load argument is invalid. They need to explain how their ideas comport with the data on genome size (The Onion Test). They need to explain why the average gene needs 5000 regulatory sites. They need to come up with a reasonable explanation for lack of sequence conservation. They need to tell us why the vast majority of defective transposons evolved a function.

Opponents of junk DNA need to address the arguments and evidence for junk DNA and stop pretending that those arguments don't exist.

Where Do Organisms Get Their Energy?

I've been thinking a lot about fundamental concepts in biochemistry. One of them has to be energy—where do cells and organisms get the energy to grow and divide?

Most of the metabolism section of biochemistry courses in North America are taught from an anthropomorphic, fuel metabolism perspective. That's understandable since the purpose of such courses is mostly to prepare students for the MCAT exam. (Medical school entrance exam.) I prefer an evolutionary approach to teaching biochemistry but that's not very popular these days.

By the time the course is over, students will have learned that humans get their energy from food, especially glucose. The next step is to ask where the glucose comes from. The simple answer is that food (i.e. glucose) comes from plants. The next question is where do plants get the energy to make glucose? The answer is, of course, sunlight. This should lead to an explanation of photosynthesis but that rarely happens in introductory biochemistry courses.

This description leads to the classic "food chain" as shown in the figure (above) from FT Exploring Science and Technology [The Flow of Energy Through Plants and Animals]. This is conceptually sound biochemistry as far as it goes. As long as students understand how sunlight can be used to make ATP and how ATP can be used to make macromolecules (including glucose), then they will understand that humans ultimately get their energy from sunlight. I would be happy if all biochemistry students could explain this food chain at the molecular level.

But in order to make sure that students really understand this process, I go one step further. I explain that there are many species of bacteria that are chemoautotrophs. Chemoautotrophs are incapable of photosynthesis yet they are able to grow and divide in the absence of any organic compounds. Their carbon source is CO₂, just like photosynthetic organisms. These bacteria have a basic metabolism that teaches us what primitive life forms must have been like. Knowing how they get their energy helps students understand evolution.

Where do chemoautotrophs get their energy? I'm interested in knowing how many readers have taken biochemistry and are able to answer that question. Please let me know in the comments before you read the answer in these posts [Carbon Dioxide Fixation in the Dark Ocean] [Core Concepts: Pathways and Transformations of Energy and Matter] [Ubiquinone and the Proton Pump].

Monday's Molecule #202

The last Monday's Molecule was the pyrrolysine, 23rd amino acid. The winner was Michael Florea [Monday's Molecule #201].

Today's molecule is an enzyme. Homologous enzymes are found in all species. They play an essential role in metabolism. The green part binds the substrate and the subsequent reaction reduces a bound FAD prosthetic group (yellow). Electrons are then passed to an FAD molecule in the purple part in the orientation shown on the left. Notice that the yellow FAD molecules are close together. (The two purple parts on the left should be joined but the connection can't be resolved in the structure.) This electron transfer results in a shift in conformation to the conformation of the purple structure shown on the right. Note that the FAD molecule has shifted to a less exposed position. The purple protein then dissociates and carries electrons to an membrane-bound enzyme that transfers electrons to ubiquinol (QH₂). Name the green protein and the purple protein.

This week I'm trying a new format in order to avoid moderating comments. Email your answers to me at: Monday's Molecule #202. I'll hold off posting your answers 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.

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 email message.)

Why Do We Do Science?

Lately there's been a flurry of activity in the American press about the value (or lack of value) of science. There have also been attempts by various organizations to enhance science education.₁ Most defenders of science and science education will eventually end up trying to explain how science directly benefits the economy, usually in the form of return on investment. In other words, we need to do science because eventually the result will be used by somebody to make a profit.

I posted an example of this a few days ago [Zack Kopplin Defends Science].

I think this is a dangerous strategy. There are several ways of responding to the "what's in it for me" question without bringing up indirect economic benefit. These strategies are common when defending public support for the arts, for example. They're also used when defending research in the humanities.

Phill Plait of Bad Astronomy hits the nail on the head as far as I'm concerned [Wall Street Journal Editorial Board Member Gets Schooled on Science Funding]. His defense of science should be the primary talking point whenever anyone questions the value of learning about the natural world. Here's what Phil Plait says in response to Zack Kopplin's "return on investment" defense of science when Stephen Moore asks why the government is funding research on sex in snails.

How’s that for return on investment?

And that’s just a pedestrian, look-at-what’s-directly-in-front-of-you kind of thinking. We research the Universe around us because we are curious, inquisitive, intelligent animals. We don’t know what snail mating habits might teach us. That’s why we study it. Maybe it’ll lead into insight on how animals behave, or a new chemical secreted during the process, or to insight on the environment where snails live. Maybe none of that.

But that’s not the damn point. We study science because we want to learn about the real world. If we wanted to stick our heads in the sand, as people like Moore would have us do, he wouldn’t even have the venue he has to say ridiculous things like he just did.

Science is about exploration and discovery, and making sure we don’t fool ourselves. It’s among the noblest of all human endeavors, and something we should be both pursuing to our fullest abilities as well as defending from those who would drag it down.

Right on, Phil! Science leads to knowledge and knowledge is always better than ignorance. That's reason enough to fund science research and reason enough to support science education.

As sure as night follows day, there are going to be comments from people who advocate the "return on investment" strategy for defending science research. The argument frequently boils down to the fact that most politicians don't care about knowledge. All they want to see is how science can help business or improve the health and physical well-being of our citizens. Because these politicians are ignorant of the real value of knowledge, we must cow-tow to their ignorance and defend science on their turf.

That's what's happening in Canada with our Conservative government. In my field (biochemistry & molecular biology), many of my colleagues think we have to justify our research by showing how it will improve health. The current buzzword is "translational research." If you don't engage in the kind of research that Conservatives want, then you won't get funded.

Unfortunately, that may be true in today's climate. That doesn't mean we have to fool ourselves into thinking that that "translational research" be our primary goal. We recognize that the ignorance of our Conservative government is a problem, not a virtue. It's a problem that has to be fixed ... in the long term. Our goal should be to educate the next generation of politicians so we don't have to be embarrassed by them in the future. Let's at least have some people like Phil Plait who will speak out for basic curiosity-motivated research. We'll never succeed in convincing politicians and the general public of the value of knowledge if we don't even try.

Let's make sure we start with our students. Let's at least ensure that when we have them in our clutches as undergraduates we make sure that they understand science and the importance of knowledge. If we don't do that then we have nobody to blame but ourselves when future societies demand that science generate a return on investment.

Looking at my own university, it's obvious that we are not doing a very good job in our courses. I fear for the future of science.

1. In the USA "science" often gets lumped in with "technology," "engineering," and "mathematics"(=STEM) as though they had the same goals.
