The NRA Anti-Obama Ad

If you live outside of the USA you may not have seen this television ad paid for by the National Rifle Association.

It's tantamount to a declaration of war on the issue of gun control. What this means is that there is no compromise or middle ground with these people. I hope Obama accepts the challenge and takes on the gun lobby. Last I heard, they were not a democratically elected part of the legislature.


BTW, if members of the NRA are really interested in protecting their children from the risk of being killed by guns then they should send them to school in the UK. Even Canada would be better.

Here's another version of the ad.

[Hat Tip: Pharyngula]

Which subjects need to be added to current evolutionary theory to create a new extended synthesis?

Here's a list of subjects that have been proposed as extensions to the so-called "Modern Synthesis" of evolution. Some of them are radical changes and others are more subtle.

I'm not going to explain all of them because that would take many posts and a lot of time. Besides, most of them have been openly debated on numerous blogs over the past decade or so.

Choose the one(s) that you think are the most important.

Why Do the IDiots Have So Much Trouble Understanding Introns?

Most eukaryotic genes have introns. Introns make up about 18% of the DNA sequences in our genome. Most of these sequences are junk but introns are functional and up to 80bp of each intron is required for proper splicing. The essential sequences contain the 5′ splice site (~10 bp); the 3′ splice site (~30 bp): the branch site (~10 bp); and enough additional RNA to form a loop (~30 bp). The branch site and the splice sites are where specific proteins bind to the mRNA precursor [Junk in Your Genome: Protein-Encoding Genes]. It turns out that within introns about 0.37% of the genome is essential and about 17% is junk.

What? Me Worry?

Alfred E. Neuman may not have had a care in the world but most of us worry about something. John Brockman of The Edge asks his bevy of followers this question for 2013: 2013: WHAT *SHOULD* WE BE WORRIED ABOUT?.

You'd think that most of the responses would be along the lines of global climate change, poverty, disease, crime, war, or the possibility that Earth might be destroyed by an asteroid impact. You'd think that the treatment of women in third (and second) world countries and the fanaticism of religious extremists might generate more than a few responses.

You would be wrong.

Here's what the best minds in the Western world came up with. I read most of them and I don't think I'll lose any sleep over any of these worries. I will, however, continue to lose sleep over women being raped in India and young children being shot to death in Connecticut.

How Atheists Cope with Death

There are millions and millions of atheists around the world. Whether it's in Brussels or Beijing these atheists cope with deaths in the family in a variety of ways. None of them require the false comfort of god(s) or heaven.

I live in a (relatively) secular society. Most of my friends are nonbelievers. We are at the age where the deaths of friends and family members are not uncommon. In many cases, the memorial services are completely non-religious but even in those cases where the service takes place in a church my friends are not troubled by their lack of belief in god(s).

However, problems arise in societies where the vast majority of people are religious and where the believers have no concept of what it might be like to be an atheist. The problems aren't caused by the inability to cope with death in the absence of god, they are caused by intolerant and insensitive believers who can't, or won't, recognize that their false beliefs provide no comfort to an atheist. That's why there's so much talk these days about how atheists cope with death in the USA [After Tragedy, Nonbelievers Find Other Ways To Cope].

If you read the examples in that article, you will realize that the problems they face would not exist in non-religious societies. Their "problems" all stem from feelings of guilt about not believing or from interfering Christians. You won't see articles like this published in Brussels or Beijing.

What Exactly Is Evolution? Stated Clearly Gets It Mostly Right

Stated Clearly posts videos on YouTube. It is dedicated to "spreading the love of science to the world" [Stated Clearly, YouTube] [Stated Clearly, Website].

The video below, narrated by Jon Perry, answers the question, What Exactly Is Evolution. It starts with an excellent definition of evolution that closely resembles my own preferred, minimal, defintion of evolution at What Is Evolution?. Here's the definition in the video ...

(Evolution is defined as) any change in the heritable traits within a population across generations.

The first example involves a new mutation that arises in an amoeba-like organism. Because this new mutation in inherited by a daughter cell, the video declares that "evolution has officially occurred."

What this means is that mutation becomes a mechanism of evolution. I prefer to think of evolution as "heritable changes in a population spread over many generations" in order to make it clear that change in a single generation doesn't qualify. I also prefer to think of mutation as a mechanism for generating variation and not a mechanism for causing evolution but this can be legitimately debated.

The second example is two badgers mating to produce an offspring that has a different combination of characteristics than either parent. According to the video "evolution ... has officially occurred." This is incorrect. Populations evolve, not individuals. It's quite possible for the individuals in a given generation to have different combinations of traits than either of their parents while the frequency of alleles in the population remains unchanged. Thus, evolution has NOT occurred.

The idea that it's populations that evolve and not individuals is crucial to a correct understanding of evolution and it's a shame that the video promotes a common misconception.

Bug_girl at Skepchick liked this video and so did PZ Myers at Pharyngula.

WTF Is Science?

Rufina is a student at the University of Toronto and she's interested in setting up a group/club to discuss science. Here's what she has in mind.

The goal of this group is to meet regularly (~biweekly) to discuss/debate the hot topics in scientific controversy and their implications in the sociopolitical world. My personal aim in founding this group is to refine the art of delivering articulate and diplomatic scientific explanations to those who don't "believe" in science. In addition, I would like to expand our efforts to somehow elucidating to the general public/non-science students the importance of science in the progress of society.

I'm in.

The first meeting will be Wednesday, January 1623, 2013 at 6pm at a location to be decided. (Probably in my building.) The topic of the first meeting is "What Is Science."

Anyone else want to join us?

Is It Time for All Religions to Accept Evolution?

This is a BBC One program posted to YouTube on Jan. 13, 2013. The question is whether it's time for all regions to accept evolution. The answer is "yes" of course, but some religions are going to resist for a bit longer. Because this is Britain, it's not so much the Christians that are the problem but Muslims.

You will recognize some of the people on this program. Matt Ridley, for example, gives a pretty good answer to the question about whether there's a scientific debate about the fact of evolution. It's amusing to read the response of Cornelius Hunter who claims that everything Ridley says is a lie [Here is How Evolutionists Lie to the Public].

Hunter says,

That was such a dizzying flurry of big lies we, frankly, lost count. Those lies are so absurd, so unequivocally false, and spoken with such conviction, that the average person is sure to believe them.

Unfortunately such lies are the rule rather than the exception. This evolution propaganda segment was no mistake—it is unfortunately typical.

Of course one can make truthful arguments for evolution. And one can try to find scientific evidence to support it. It is not easy, but it can be done. But that is not what evolutionists do. They mandate evolution. They insist evolution is a fact in spite of the evidence. And that is a big lie.

I don't think we're ever going to succeed in teaching the Cornelius Hunter's of this world the difference between truth and lies but TV shows like this one are having an impact and I'm glad to see that some Muslims are willing to speak out.

Shows like this one were very rare in the 20th century. It's now become much more acceptable to challenge religious beliefs that conflict with science and I think that's because of outspoken atheists like Richard Dawkins, Daniel Dennett, Christopher Hitchens, and Sam Harris, along with many other so-called "New Atheists."

Monday's Molecule #197

The last "Monday's Molecule" was β-D-mannopyranose, shown in boat and chair configurations [Monday's Molecule #196]. The winners were Bill Chaney, Dima Klenchin, and Bill Gunn. Bill Gunn should contact me if he is within range of Toronto.

Students often find it very difficult to distinguish between various stereoisomers. For example, many of you thought that the last molecule was glucose. This week's molecule should present a real challenge for most of you. It's a common molecule, present in all cells and it has a common name by which it is identified in most textbooks. However, the common name isn't good enough because there are several different conformations. The conformation shown in the figure is the only one that's synthesized in the normal reaction. Name this molecule using whatever conventions you have to employ to identify it correctly. [Hydrogen atoms are omitted for clarity. You should be able to infer their positions.]

Post your answer as a comment. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.)

The Great Wrinkled Finger Debate

The students in my Molecular Evolution class have to read the Spandrels paper by next Tuesday.

Ryan Gregory explains why this 35-year-old paper is just as relevant and important today as it was when it was first presented in 1978 (published in 1979). Read aall about it at: The great wrinkled finger debate.

The Problem with Selling the Homeopathic Product Oscillococcinum

A group of skeptics have banded together to sue Shoppers Drug Mart for selling the homeopathic product Oscillococcinum. Watch the video on Think Again! TV produced by Centre for Inquiry, Canada. This is a class action lawsuit and anyone who has purchased Oscillococcinum from Shoppers Drug Mart may join the plaintiffs.

CFI is not a plaintiff but it has agreed to provide the court with "accurate scientific data on the efficacy and substance of the product."

Jim Yeager Shows Americans Why Banning Assault Guns Is Necessary

My American friends need to watch this video. Be afraid, be very afraid.

I don't know how many people think like this but if it's more than a few thousand there's going to be trouble.

Isn't threatening to kill somebody a crime? Isn't he advocating the overthrow of the democratically elected American government by force? I don't think that's in the Constitution.
