Climbing Mount Improbable as Metaphor

 One of my postings, Good Science Writers: Richard Dawkins, has been re-posted on RichardDawkins.net. This doesn't happen very often—in fact this may be the very first time. I can't imagine why they would have selected this particular posting. I mentioned that some of the Dawkins metaphors are misleading and I suggested that Climbing Mount Improbable was one example. That prompted a comment

Nobel Laureate: George de Hevesy

  The Nobel Prize in Chemistry 1943. "for his work on the use of isotopes as tracers in the study of chemical processes" George de Hevesy (1885 - 1966) received the 1943 Nobel Prize in Chemistry for his work on tracing the synthesis of biological molecules using radioactive isotopes, such as 32P. He was able to show, for example, that 32P is readily incorporated into phosphatides (lipids)

The Goal of a Science Education

 We've recently been debating the purpose of our undergraduate program in biochemistry. There are some who think that the main goal is to teach students how to do biochemistry. Those biochemists want as many lab courses as possible and they want to provide plenty of opportunities for students to carry out research projects in a research lab. In some cases, they want to minimize the number of

Good Science Writers: Richard Dawkins

 Richard Dawkins was not included in Richard Dawkins' book: The Oxford Book of Modern Science Writing. The reason for the omission is obvious, so I rectify the "oversight" by including him in my list of good science writers. I don't always agree with what Dawkins writes but there's no controversy about his ability to explain biology to the general public. He has a clear, crisp style that's easy

Getting Rid of “Darwinism” in New Scientist

 Last week, Olivia Judson published a controversial article on the New York Time website. She made the case for getting rid of terms like "Darwinism" and "Darwinian" to describe modern evolutionary biology [Let’s Get Rid of Darwinism]. I'm in complete agreement as I've stated on many occasions [see Why I'm Not a Darwinist]. The main point, as far as I'm concerned, is that modern evolutionary

Monday’s Molecule #81

 Today's molecule is not a specific molecule but rather a type of molecule. You have to identify the type of molecule shown here. There's a connection between today's molecule and a Nobel Prize. The clue is the red "P" atom in the molecule. The Nobel Prize was awarded for discovering where that red "P" came from and how quickly this type of molecule was produced. Similar studies were done with

Gene Genie #34

 The 34th edition of Gene Genie has been posted at ScienceRoll [Gene Genie 34: Summertime]. This is the first time I host Gene Genie since January. Gene Genie is the blog carnival of clinical genetics and personalized medicine. Enjoy the numerous posts and articles focusing on these interesting fields of medicine.The beautiful logo was created by Ricardo at My Biotech Life. The purpose of this

Species-Scape

 This is a snapshot of an animated picture of a "species-scape." The size of the organisms represent their relative abundance on Earth. See Species-Scape on the Cornell University website. Another version is shown on Christopher Taylor's blog Catalogue of Organisms [The Species-Scape Picture]. Notice how insignificant mammals are, yet one particular species of mammal has the potential to ruin

Nobel Laureate: George Palade

  The Nobel Prize in Physiology or Medicine 1974. "for their discoveries concerning the structural and functional organization of the cell" George E. Palade (1912 - ) received the Nobel Prize in Physiology or Medicine for his contribution to understanding how proteins are synthesized and secreted in eukaryotic cells. He worked mostly on the secretory (exocrine) cells of guinea pig pancreas

The Ethical Frontiers of Science

 I'm at the Chautauqua Institution this week where the theme is The Ethical Frontiers of Science. Today's speaker was Arthur Caplan Professor of Bioethics at the University of Pennsylvania. His topic was "Is it Immoral to Want to Live Longer, Be Smarter and Look Better?" The answer is no, it is not immoral. There's nothing wrong with wanting to take advantage of modern scientific advances to

Monday’s Molecule #80

 Today's molecules are the little black blobs in the photograph. One of them is circled in the lower left-hand corner. There's a direct connection between today's molecule and a Nobel Prize. In fact, the photograph was lifted directly from the Nobel lecture of the prize winner. The prize was awarded for determining the role of those little black blobs in the type of cell shown in the photo.

Good Science Writers: Sean B. Carroll

 Sean B. Carroll is Professor of Molecular Biology and Genetics at the University of Wisconsin in Madison, Wisconsin (USA).1 His research interests focus on evolution and development, mostly in fruit flies and other insect. Carroll is one of the leading advocates of a new approach to evolution arising out of what we have learned from animal development ("evo-devo"). (See the official Sean B.

The Fluctuation Test

 John Dennehy of The Evilutionary Biologist continues his almost perfect1 record of picking important papers for his Citation Classic. This week's paper is the classic 1943 paper by Luria and Delück on the fluctuation test [The Fluctuation test]. This was the paper that proved that mutations arise randomly with respect to their phenotype. As John says, it is one of the most important

Good Science Writers: Eugenie Scott

 Eugenie C. Scott has been the Executive Director of the National Center for Science Education (NCSE) since 1987. She is a physical anthropologist who taught at several universities prior to becoming director of NCSE.

Was Charles Darwin a Good Science Writer?

 Olivia Judson is a research fellow at Imperial College in London (UK). She studies evolution. Judson is a former pupil of W.D. Hamilton. She is also the daughter of Horace Freeland Judson.1 Judson writes a weekly article for the New York Times website. This week she tackles the heretical question of whether Charles Darwin was a good science writer [An Original Confession]. Here's a treaser ...

Tangled Bank #109

 The latest issue of Tangled Bank is up at Greg Laden's Blog [The Tangled Bank #109: LOL Evolution!]. Welcome to the One Hundred and Ninth Edition of The Tangled Bank, the Weblog Carnival of Evolutionary Biology. This is the LOL edition of the Tangled Bank.... If you want to submit an article to Tangled Bank send an email message to host@tangledbank.net. Be sure to include the words "Tangled Bank

A Gene Wiki

 The prevalence of errors and omissions in sequence databases is one of the ugly little secrets of molecular biology [Errors in Sequence Databases]. We know how to fix the problem; it requires careful annotation by knowledgeable experts. Unfortunately, this is time-consuming and expensive since you have to hire annotators. One other possibility is to allow open access to all existing records in

Flatfish

 Flatfish are strange looking animals that live sideways. One of their eyes has migrated to one side of the fish so that when it lies on its "side" at the bottom of the ocean both eyes point upwards. This is an interesting example of the evolution of a change in development. Fossil relatives of modern flatfish have recently been described and they confirm much of what was surmised about the

Good Science Writers: G. Brent Dalrymple

 G. Brent Dalrymple is a geologist at Oregon State University (now retired). He received the National Science Medal in 2005. This is the USA's highest award for scientific achievement. Dalrymple has published two books on the age of the Earth: The Age of the Earth (1991), and Ancient Earth, Ancient Skies: The Age of Earth and Its Cosmic Surroundings (2004). The first book grew out of his

Good Science Writers: Jacques Monod

 Jacques Monod (1910 - 1976) received the Nobel Prize in Physiology or Medicine (1965) for his work on the regulation of the lac operon (with François Jacob). While best known as a biochemist, Monod was also well respected for his many articles on politics and philosophy. Dawkins didn't select anything from Monod for The Oxford Book of Modern Science Writing because his selections were limited

Nobel Laureate: Peter Agre

  The Nobel Prize in Chemistry 2003. "for the discovery of water channels" Peter Agre (1949 - ) received the 2003 Nobel Prize in Chemistry for discovering the water channel protein known as aquaporin (AQP1). Aquaporin is a membrane protein that forms a channel in the membrane. The channel specifically allows water molecule to diffuse across the membrane. No other ions or molecules can pass

The Three Fatal Flaws in the Theory of Evolution

 Thanks to PZ Myers for finding an important new website called Darwin Conspiracy. It highlights the three faltal flaws in the Theory of evolution. You have never read about any of these fatal flaws before. Evolution scientists know about these flaws, but they have successfully covered them up with the help of a worldwide Darwin Conspiracy that actively suppresses the fact that Darwinism is not

Good Science Writers: Steven Vogel

 Steven Vogel is a Professor in the Biology Department at Duke University (N.C., USA). His main research interest is comparative biomechanics. He studies things like the design of fly wings and how organisms adapt to fluids (air and water). His secondary interest is science writing and he has published four books: Life's Devices: The Physical World of Animals and Plants (1988); Cats' Paws and

Evolution Education

 Last year the McGill Journal of Education published a special issue on teaching evolution. One of the most interesting articles was by Craig Nelson on TEACHING EVOLUTION EFFECTIVELY: A CENTRAL DILEMMA AND ALTERNATIVE STRATEGIES. Nelson points out that much of the blame for the evolution/creation controversy stems from poor teaching of evolution in the high schools. The two most obvious failed

“Rational” Arguments for the Existence of God

 The current issue of Christianity Today contains an article by William Lane Craig entitled God Is Not Dead Yet: How current philosophers argue for his existence. Craig is a Professor of Philosophy at the Talbot School of Theology of Biola University, an evangelical Christian college near Los Angeles. His website is Reasonable Faith. The article is a defense of theology in the face of attacks by

Monday’s Molecule #79

 What is this protein doing and what is its name? You don't need to identify the species. There's a direct connection between today's molecule and a Nobel Prize. The prize was awarded for discovering this molecule and recognizing that its function was exactly what had been long predicted. The first person to correctly identify the molecule and name the Nobel Laureate(s), wins a free lunch at

The Evolution of Flowering Plants

 A lot more is known about the evolution of flowering plants than most people realize. Christopher Taylor over at Catalogue of Organisms1 has done the homework and posts a must-read article on the subject [The Origins of Flowers]. He begins by asking the questions, "... what exactly makes flowering plants so distinct? What do they have that no other plant has?" Think of the answers, then get on

Good Science Writers: Richard Lewontin

 Richard "Dick" Lewontin (1929 - ) is Alexander Agassiz Research Professor at Harvard University (Boston, USA). He is a well-known geneticist and the discoverer of extensive variation in organisms at the molecular level, with John Hubby [Citation Classic]. (See The Cause of Variation in a Population.) Lewontin is also one of the authors of the textbook Modern Genetic Analysis. It's impossible to

Cuss Level

 Canadian Cynic scored 19.5% on the Cuss-O-Meter [It's all fucking relative, isn't it?]. This isn't a big surprise, although in person (s)he doesn't swear nearly as much as on the blog. I couldn't resist entering Sandwalk to see how I do. Hmmm ... 5.2% of my pages have "cuss" words. I wonder what they are? Does "IDiot" count?

Good Science Writers: Niles Eldredge

 Niles Eldredge ranks as one of the best science writers among professional scientists, in my opinion.1 What I like about Eldredge is that he does not disguise his biases by ignoring all those who disagree with him. Instead, he tries to explain why his view of biology is correct. In this sense he is like Richard Dawkins, although he differs significantly from Dawkins because he (Eldredge) is
