Extraordinary claims, as the saying almost goes, demand more scrutiny than usual to make sure they stand up. That is how science works. Claim and counter-claim: intellectual thrust and experimental parry.They report on an upcoming meeting meeting of the Council for the Advancement of Science Writing in Columbus Ohio. Apparently, this council is composed of scientists and journalists and the goal of the meeting is to search for "lessons learned by scientists and science writers" in light of their publicity campaign promoting the flawed paper.
The first thing to highlight is that such a thing as the Council for the Advancement of Science Writing even exists. Too many scientists dismiss the media and journalists as sloppy and unwilling to engage in both detail and ambiguity. In fact, there can be no branch of journalism as self-scrutinizing and anxious about its performance as that which covers science. It is hard to imagine political and sports reporters taking the time to discuss so thoroughly what (if anything) they did wrong after one of their stories went belly-up.Indeed, that's admirable, but it's another example of journalistic hyperbole. I do not believe that this branch of journalism (science writing) is as "self-scrutinizing" as they would have us believe. I do not believe that science writers usually debate and discuss what they did wrong when a story goes belly-up.
The (welcome) rise of the science blogger has fuelled this navel-gazing. Some bloggers seem to spend most of their time criticizing other science writers, or at least debunking examples of what they regard as inferior science writing. But they do lots of good stuff too. Although traditionalists lament the decline of science coverage in the mainstream press, a terrific amount of analysis and comment, much of it very technical, is happening online under their noses.There's an interesting slip of the tongue in that paragraph. If science writers are really interested in self-scrutiny then they should welcome the arrival of a group of bloggers who point out their errors. This should be a "good" thing but the Nature editors clearly contrast this role (criticizing science writers) with other "good stuff" that bloggers do. Apparently the criticism of science writing doesn't count as "good stuff." It just makes science writers anxious—which they weren't before science bloggers came on the scene and pointed out what a bad job they were doing.
Some may question the timing of the announcement, made when the paper was released on the Internet, not accepted or published by a journal, but at least the evidence was there to examine. If the scientists and the media both largely acted properly, then what should be discussed at next week’s meeting? It could do worse than start by screening the celebratory online video produced by ... and released to accompany the announcement. Scientists and journalists can include as many academic caveats as they like, but the sounds and images of champagne corks popping tend to render such statements of caution just that — academic.I bet you're thinking that this is all about the ENCODE publicity campaign and how Nature was totally at fault for misrepresenting the data and hyping the false claims of the ENCODE Consortium.
There is a deeper issue here: science not by press conference but presented as an event. What in reality is a long, messy and convoluted process of three steps forward and two steps back is too easily presented as giant leaps between states of confusion and blinding revelation. At the heart of this theatre is the artificial landmark of a peer-reviewed paper. Fixed print schedules and releases to journalists under embargo (with or without champagne videos) help to lend the impression that the publication of a paper is the final word on a question — the end-of-term report on a scientific project that details all that was achieved.
Perhaps Coyne might be interested to read an eye-opening article by Carol Brown over at American Thinker on what is happening in Denmark. Ms. Brown paints a terrifying portrait of a society which is falling apart under the influence of religiously motivated violence. Crime in Denmark has exploded, and street gangs "have taken over large parts of Danish towns and cities. There are numerous "no go" zones where even the police are afraid to venture. Is this Coyne’s idea of a successful secular society?I was in Denmark for seven days and I never saw any sign of this sort of lawlessness or even heard about it. But maybe I was just in the wrong places? Or maybe it's not true? (Heavens!)
Some morals to be drawn from Brown’s article:
1. Not all forms of religion are good; some are toxic.
2. Nature abhors a vacuum. Secularism is powerless to drive out toxic forms of religion.
3. The only proven way to drive out toxic forms of religion, and keep them out, is with wholesome forms of religion.
Tour signed Discovery's Scientific Dissent from Darwinism years ago when the National Center for Science Education asserted that only a handful of scientists doubt Darwin's theory. Our list of dissenters started at 100, then grew to 800. At that point we stopped inviting people to sign it because their names on the list were used by Darwinists to persecute them professionally. Some lost their jobs.Maybe we should consider the possibility that that a synthetic organic chemist is not an expert on biology? Naw, that would require the application of skepticism [How to use selective hyperskepticism to debate Darwinists].
However, Tour doesn't seem to have been hurt. Is that possibly because chemists are more open-minded than biologists? Or is the dirty little secret about Darwinism -- that it has more public advocates in science than private believers -- becoming more apparent?

It seems that rather regularly there is a debate within evolutionary biology, or at least in public about evolutionary biology, where something new and bright and shiny is going to revolutionize the field. In general this does not pan out. I would argue there hasn’t been a true revolution in evolutionary biology since Mendelian genetics and classical Darwinism were fused in the 1920s and 1930s during the period when population genetics as a field was developed, and the famous "synthesis" developed out of the interaction of the geneticists with other domains of evolutionary relevance. This does not mean that there have not been pretenders to the throne. Richard Goldschmidt put forward his "hopeful monsters," neutralism reared its head in the 1970s, and evo-devo was all the rage in the 2000s. Developments that bore scientific fruit, such as neutralism, were integrated seamlessly into evolutionary biology, while those that did not, such as Goldschmidt’s saltationism fell by the wayside. This is how normal science works.The main point here is whether Neutral Theory and an increased emphasis on random genetic drift "were integrated seamlessly" into the Modern Synthesis view that was popular in the 1960s. Is it true that the way modern population geneticists look at evolution is just a little bit different from the way evolutionary biologists thought about evolution in the 1920s, 1930s, and 1940s? I don't think so. I think there's been a significant shift—so much so that we can no longer refer to the "Modern Synthesis" as the most modern version of evolutionary theory.
But every now and then you have a self-declared tribune of the plebs declaring that the revolution is nigh. For decades the late Stephen Jay Gould played this role to the hilt, decrying "ultra-Darwinism," and frankly misrepresenting the state of evolutionary theory to the masses from his perch as a great popularizer. More recently you have had more muted and conventional revisionists, such as Sean Carroll, who promote a variant of evo-devo that acclimates rather well to the climes of conventional evolutionary biology.I do not believe that Gould misrepresented evolutionary theory to the masses. I believe that Richard Dawkins misrepresented evolutionary theory to the masses.
Nature now has a piece out which seems to herald the launching of another salvo in this forever war, Does evolutionary theory need a rethink? It’s written in the form of opposing dialogues. I’m very much in the camp of those believe that there’s no reason to overturn old terms and expectations. Evolutionary biology is advancing slowly but surely into new territory. There’s no problem to solve. The one major issue where I might have to make a stand is that it focusing on genetics is critical to understanding evolution, and dethroning inheritance from the center of the story would eviscerate the major thread driving the plot. The fact that evolutionary biologists have the conceptual and concrete gene as a discrete unit of information and inheritance which they can inspect is the critical fact which distinguishes them from fields which employ similar formalisms but have never made comparable advances (such as economics).I agree with Razib Khan that genetics (population genetics) is the key to understanding evolutionary theory at the population level. I think we disagree on exactly what version of population genetics we support and on the importance of adaptation.

... hyper-skepticism (which is certainly not a term we made up … just google it) is virtually never equitable. Rather it is highly selective. Selective Hyper-Skepticism results when one requires a much higher degree of warrant in order to accept things that they prefer weren’t true. It most often comes up when worldview issues are at stake. It’s the application of a double-standard where one demands sufficient evidence to support absolute certainty (which is generally impossible) on certain facts they’d rather not have to believe, but they are willing to accept a much more lax standard of evidence and argumentation on matters of a very similar profile that don’t threaten their worldview. It also happens that someone demonstrating hyper-skepticism on these types of worldview issues often displays hyper-credulity towards arguments and evidence on the matter that is consistent with their own worldview. This isn’t really an accident, because the hyper-skepticism applied on one side of the equation often leaves the person grasping for any contrary evidence or argument at all on the other side of the equation, no matter how implausible or unsubstantiated.Now, Gordon Elliot Mullings doesn't give any examples of how to use this technique to debate Darwinists but I can think of a few examples.
UCSF scientists find shorter telomeres in immune cells of soda drinkers
Sugar-sweetened soda consumption might promote disease independently from its role in obesity, according to UC San Francisco researchers who found in a new study that drinking sugary drinks was associated with cell aging.
The study revealed that telomeres — the protective units of DNA that cap the ends of chromosomes in cells — were shorter in the white blood cells of survey participants who reported drinking more soda. The findings were reported online October 16, 2014 in the American Journal of Public Health.
The length of telomeres within white blood cells — where it can most easily be measured — has previously been associated with human lifespan. Short telomeres also have been associated with the development of chronic diseases of aging, including heart disease, diabetes, and some types of cancer.
"Regular consumption of sugar-sweetened sodas might influence disease development, not only by straining the body's metabolic control of sugars, but also through accelerated cellular aging of tissues," said Elissa Epel, PhD, professor of psychiatry at UCSF and senior author of the study.
"This is the first demonstration that soda is associated with telomere shortness," Epel said. "This finding held regardless of age, race, income and education level. Telomere shortening starts long before disease onset. Further, although we only studied adults here, it is possible that soda consumption is associated with telomere shortening in children, as well."
The authors cautioned that they only compared telomere length and sugar-sweetened soda consumption for each participant at a single time point, and that an association does not demonstrate causation. Epel is co-leading a new study in which participants will be tracked for weeks in real time to look for effects of sugar-sweetened soda consumption on aspects of cellular aging. Telomere shortening has previously been associated with oxidative damage to tissue, to inflammation, and to insulin resistance.
Based on the way telomere length shortens on average with chronological age, the UCSF researchers calculated that daily consumption of a 20-ounce soda was associated with 4.6 years of additional biological aging. This effect on telomere length is comparable to the effect of smoking, or to the effect of regular exercise in the opposite, anti-aging direction, according to UCSF postdoctoral fellow Cindy Leung, ScD, from the UCSF Center for Health and Community and the lead author of the newly published study.
The average sugar-sweetened soda consumption for all survey participants was 12 ounces. About 21 percent in this nationally representative sample reported drinking at least 20 ounces of sugar-sweetened soda a day.
"It is critical to understand both dietary factors that may shorten telomeres, as well as dietary factors that may lengthen telomeres," Leung said. "Here it appeared that the only beverage consumption that had a measurable negative association with telomere length was consumption of sugared soda."
The finding adds a new consideration to the list of links that has tied sugary beverages to obesity, metabolic syndrome, type 2 diabetes, and cardiovascular disease, and that has driven legislators and activists in several U.S. jurisdictions to champion ballet initiatives that would tax sugar-sweetened beverage purchases with the goal of discouraging consumption and improving public health.
The UCSF researchers measured telomeres after obtaining stored DNA from 5,309 participants, ages 20 to 65, with no history of diabetes or cardiovascular disease, who had participated in the nation's largest ongoing health survey, called the National Health and Nutrition Examination Survey, during the years 1999 through 2002. They found that the amount of sugar-sweetened soda a person consumed was associated with telomere length, as measured in the laboratory of Elizabeth Blackburn, PhD, professor of biochemistry at UCSF and a winner of the 2009 Nobel Prize in Physiology or Medicine for her telomere-related discoveries.

Heterochromatin is a significant component of the human genome and the genomes of most model organisms. Although heterochromatin is thought to be largely non-coding, it is clear that it plays an important role in chromosome structure and gene regulation. Despite a growing awareness of its functional significance, the repetitive sequences underlying some heterochromatin remain relatively uncharacterized. We have developed a real-time quantitative PCR-based method for quantifying simple repetitive satellite sequences and have used this technique to characterize the heterochromatic Y chromosome of Drosophila melanogaster. In this report, we validate the approach, identify previously unknown satellite sequence copy number polymorphisms in Y chromosomes from different geographic sources, and show that a defect in heterochromatin formation can induce similar copy number polymorphisms in a laboratory strain. These findings provide a simple method to investigate the dynamic nature of repetitive sequences and characterize conditions which might give rise to long-lasting alterations in DNA sequence.
logically_speaking says:I wonder how that's working out? If design was only detected by Bill Dembski and Michael Behe then they've only had a few years to think about who the designer might be. I wonder what they've come up with? Who are the leading suspects?
In my opinion questions such as who was the designer and who designed the designer are only important after design has been detected. In fact this is how many branches of scientific endeavor must proceed. Ask any detective at a crime scene, do they ask who was the murderer before answering the question of was any murder committed in the first place.
There are two separate questions (1) was there design and (2) who was the designer. It really is a common sense observation that the second question is logically downstream from the first. It is a corollary to that common sense observation that anyone who insists that one cannot address the upstream question until one has resolved the downstream question is either deeply confused or has an agenda unconnected with discovering the truth of the matter.Imagine that! Some people have an agenda that's unconnected with discovering the truth!
Is this going to be controversial?The Nobel Prize in Physiology or Medicine 2014 was awarded with one half to John O'Keefe and the other half jointly to May-Britt Moser and Edvard I. Moser "for their discoveries of cells that constitute a positioning system in the brain".
How do we know where we are? How can we find the way from one place to another? And how can we store this information in such a way that we can immediately find the way the next time we trace the same path? This year´s Nobel Laureates have discovered a positioning system, an “inner GPS” in the brain that makes it possible to orient ourselves in space, demonstrating a cellular basis for higher cognitive function.
In 1971, John O´Keefe discovered the first component of this positioning system. He found that a type of nerve cell in an area of the brain called the hippocampus that was always activated when a rat was at a certain place in a room. Other nerve cells were activated when the rat was at other places. O´Keefe concluded that these “place cells” formed a map of the room.
More than three decades later, in 2005, May-Britt and Edvard Moser discovered another key component of the brain’s positioning system. They identified another type of nerve cell, which they called “grid cells”, that generate a coordinate system and allow for precise positioning and pathfinding. Their subsequent research showed how place and grid cells make it possible to determine position and to navigate.
The discoveries of John O´Keefe, May-Britt Moser and Edvard Moser have solved a problem that has occupied philosophers and scientists for centuries – how does the brain create a map of the space surrounding us and how can we navigate our way through a complex environment?
In most debates, especially arguments over the internet, each side brings along a list of premises, premises that originally gave rise to their conclusions and often go unaddressed. Unless a counter argument addresses any of these often unstated premises, all it accomplishes is bringing in a whole new set of premises to be addressed, and nobody gets anywhere.This is a laudable objective. I fully support the concept.
Given a recent list I saw floating around twitter titled "10 commandments of faitheism," which is nothing but a list of things nobody associated with the term "faitheist" actually believes, I thought it would be a good exercise to try to list all of premises that we at NPS, at least, bring to the table. I should state upfront that, obviously, only Chris Stedman can speak for Chris Stedman, but since most people lump us at NPS in with him anyway and “faitheist” is the most convenient term on hand right now, I decided to use it.
At first sight, the idea that chemiosmosis is a very ancient means of energy transduction might seem counterintuitive. More familiar to many is the old (and popular) doctrine that the most ancient pathway of energy metabolism is a fermentation such as glycolysis [77], an idea that goes back at least to Haldane [2] and hence arose long before anyone had a clue that biological energy can be harnessed in a manner that does not involve substrate-level phosphorylations and ‘high-energy’ bonds [149,150]. In modern life, all biological energy in the form of ATP comes ultimately from chemiosmotic coupling [151], the process of charge separation from the inside of the cell to the outside, and the harnessing of that electrochemical gradient via a coupling factor, an ATPase of the rotor–stator-type. It was not until the 1970s that it became generally apparent that Mitchell [152] was right, his Nobel prize coming in 1978, and it is hard to say when it became clear to microbiologists that all fermentative organisms are derived from chemiosmotic ancestors. We also note that Mitchell's consideration of the problem of the origin of life introduced key concepts of his later chemiosmotic hypothesis, including a definition of life as process, and the idea of vectorial catalysis across a membrane boundary that is inseparable either from the environment or from the organism itself [153].
The maxim that glycolysis is ancient might be an artefact of experience, since it was the first pathway both to be discovered and that we learned in college; in that sense, it really is the oldest. When one suggests that chemiosmotic coupling in methanogens or acetogens might be ancient, many listeners and readers shy away, mainly because the pathways are unfamiliar and often entail dreaded cofactor names.

Scholars have long acknowledged that scientific revolutions, along with their paradigm shifts, happen in human history. Yet rarely do we have an opportunity to witness such a shift first hand or to have such a clear and careful explanation of one. William Dembski's painstakingly detailed explication of the shift from the material age to the information age in science and philosophy is a brilliant and rare example. As both a philosopher and a mathematician, Dembski is metaphysically and methodologically able to delineate this shift, having previously written in both areas as well as developed a statistical method for inferring intelligent causation.I'd like to welcome Mary Poplin to the land of IDiots. I think she'll fit right in.
This book extends his earlier work and asks the most basic and challenging question confronting the 21st century, namely, if matter can no longer serve as the fundamental substance of reality, what can? While matter was the only allowable answer of the past century to the question of what is ultimately real (matter's origin, on its own terms, remaining a mystery), Dembski demonstrates there would be no matter without information, and certainly no life. He thus shows that information is more fundamental than matter and that intelligible effectual information is in fact the primal substance.
Storbeck/Pimentel, the search firm helping FSU select its next leader, conducted surveys following each candidate's campus forums last week. Thrasher received favorable ratings from only 11 percent of the responders, while 87 percent said he was not fit to be FSU's president. By comparison, the other three candidates had favorable scores between 78 and 91 percent.Apparently the Board of Governors don't care what the students and faculty think. What could possibly go wrong?
The FSU Faculty Senate, which represents all 16 colleges at the university, passed a unanimous resolution Friday calling for the trustees to hire one of the three academics among the four finalists.
"We deserve a president who plays on the national stage, one who walks the walk, one who won't put off potential donors in the other party," Michael Buchler, a music professor and faculty senator, said during the public comment period. "FSU has never hired a president who didn't have experience in the classroom."
The information encoded in our genes is translated into proteins, which ultimately mediate biological functions in an organism. Messenger RNA (mRNA) plays an important role, as it is the molecular template used for translation. Scientists from the Helmholtz Zentrum Muenchen and the Technische Universität Muenchen, in collaboration with international colleagues, have now unraveled a molecular mechanism of mRNA recognition, which is essential for understanding differential gene regulation in male and female organisms. The results are published in the renowned scientific journal Nature.It took me a few minutes to track down the article because there weren't many hints in the press release. Turns out it still hasn't appeared in the print copy but it's available online.

Researchers in Biomedical Informatics at IMIM (Hospital del Mar Medical Research Institute) and at the Universitat Politècnica de Catalunya (UPC) have recently published a study in eLife showing that RNA called non-coding (lncRNA) plays an important role in the evolution of new proteins, some of which could have important cell functions yet to be discovered.That sounds intriguing. Maybe I should read the paper even though it's in eLife.
Deep transcriptome sequencing has revealed the existence of many transcripts that lack long or conserved open reading frames (ORFs) and which have been termed long non-coding RNAs (lncRNAs). The vast majority of lncRNAs are lineage-specific and do not yet have a known function. In this study, we test the hypothesis that they may act as a repository for the synthesis of new peptides. We find that a large fraction of the lncRNAs expressed in cells from six different species is associated with ribosomes. The patterns of ribosome protection are consistent with the translation of short peptides. lncRNAs show similar coding potential and sequence constraints than evolutionary young protein coding sequences, indicating that they play an important role in de novo protein evolution.The study suggests that a lot of "noncoding" RNAs are being translated. The products appear to be short polypeptides of less than 100 residues.

Collectively, these studies suggest that lncRNAs may shape nuclear organization by using the spatial proximity of their transcription locus as a means to target preexisting local neighborhoods. lncRNAs can in turn modify and reshape the organization of these local neighborhoods to establish new nuclear domains by interacting with various protein complexes, including chromatin regulators. Once established, a lncRNA can act to maintain these nuclear domains through active transcription and recruitment of interacting proteins to these domains. While the mechanism for how lncRNAs establish these domains is not fully understood, it is becoming increasingly clear that lncRNAs are important at all levels of nuclear organization—exploiting, driving, and maintaining nuclear compartmentalization.It sure sounds like they are describing a particular function (nuclear organization) to the majority of lncRNAs. But what if 90% of all 10,000 lncRNAs have no function and what if only 100 of the remaining functional lncRNAs are involved in nuclear organization? That means there are 900 functional lncRNAs that play a different role in the cell?
Very few lncRNAs have been shown to have a function and there's a very good chance that most of them are spurious transcripts that have no function. However, a small percentage do seem to have a function. In this review we have identified some long noncoding RNAs that appear to be involved in nuclear organization. We propose to call these RNAs "noRNAs" for "nuclear organizer RNAs" on the grounds that once a function has been identified we should stop referring to them as lncRNAs.
1. I use "DNA regions" instead of "genes" because the definition of a gene requires that the gene product be functional. You can't call them genes unless you have demonstrated that the RNA has a function.

The following statements are so obvious as to be considered truisms.I would not want him to defend me if I were innocent. On the other hand, he might be a good choice if I were guilty because I could easily fool him into thinking that I was innocent.
1. The primordial datum: I am subjectively self-aware.
2. It is not possible even in principle to account for mental facts, such as the primordial datum, on the basis of physical facts. They are different sorts of things; therefore one cannot account for the other. Trying to account for subjective self-awareness by suggesting it is an epiphenomenon of the electro-chemical process of the brain is like saying the color blue can be reduced to its constituent banana peels.
3. It follows that a reductionist materialism is not merely false but obviously false.
4. Just as obviously, it does not follow that committed materialists will admit that reductionist materialism is false, for they have reasons to put their faith in their metaphysical commitments that have nothing to do with the evidence and logic of the matter.
