Readers’ wildlife photographs

July 26, 2016 • 7:30 am

When I’m on the road it’s easier for me to post readers’ photographs from emails than from my folder (which I’ll bring to Poland nonetheless), so by all means send me your good photograph on Friday or thereafter. Today we feature our most stalwart stalwart, Stephen Barnard from Idaho.

Stephen originally identified this as a “Female Black-chinned Hummingbird (Archilochus alexandri) in various poses,” but he now says this:

Social media is trending toward female Calliope Hummingbird (Selasphorus calliope), and I tend to agree, mostly because of the short tail compared to the Broad-tailed. The Internet is a marvelous thing. The females and juveniles of these species are very hard to tell apart.  The mature breeding males are super obvious. [JAC: I’ve put a photo of a male below.]

This bull moose (Alces alces) got Deets’s [the border collie’s] attention this morning. I like the backlighting on the velvet antlers.

I get emails: a persistent Christian

July 26, 2016 • 7:00 am

I don’t know what to do with this guy. Answering him will, as I’ve learned, only provoke more emails. I have a series of three:

September 18, 2013

Dear Dr. Coyne:

My name is [REDACTED], a college student currently. I was once an irreligious person when I was a boy; however, I have experienced a vast conversion in my life which permanently changed my character from a carnally-minded selfish, rebellious child unto a spiritually-minded being who strives to do what is right in God’s standards, which do not change.

I have learned for myself that atheism is not true. My inquiries for you are these: Do you believe that I’m idiotic, deranged, or stupid in anyway? If so, do you believe we’re better than our ancestors?
Yours truly,
[REDACTED]

“Behold, I am a disciple of Jesus Christ, the Son of God. I have been called of him to declare his word among his people, that they might have everlasting life.” – 3 Nephi 5:13
Experience has taught me that any response to this kind of email invariably triggers more emails in which the believer demands a “conversation.” Although I was tempted to answer his penultimate question, I refrained. A year later he tried again:
December 25, 2014 (Christmas Day!):

Dr. Coyne,

If you’re unwilling to answer, you could at least tell that to me. You’re probably a busy man, but it doesn’t take long to do that.

My faith remains strong. Merry Christmas, and God bless.

-[REDACTED]

Again I didn’t respond.  Another email came today, nearly 7 months later. I think the fellow is getting testy.

July 25, 2016:
Well?

Tuesday: Hili dialogue

July 26, 2016 • 6:30 am

Only two more days before I head to Poland to see my adopted parents and also to get my Hili and cherry pie fix. It’s got to be cooler there than here!

It’s July 26, which means it’s the Day of National Significance in Barbados. Also on this day, the very first reported women’s cricket match took place–in 1745! Exactly two hundred years later, Winston Churchill was removed from power in a general election. Ingrates! Finally, there’s this intriguing Wikipedia note from July 26, 2007: “Shambo, a black cow in Wales that had been adopted by the local Hindu community, is slaughtered due to a bovine tuberculosis infection, causing widespread controversy.”

Notables born on July 26 include Carl Jung (1875), Aldous Huxley (1894), Stanley Kubrik (1928), Mick Jagger (1943), Helen Mirren (1945 ♥), Dorothy Hamill (1956), Kevin Spacey (1949), and Sandra Bullock (1964♥♥). Those who died on this day include William Jennings Bryan (1925, right after the Scopes Trial), Eva Peron (1952), Diane Arbus (1971), and Merce Cunningham (2009). Meanwhile in Dobrzyn, Hili has learned that Hiroko, the Japanese woman who embroidered Hili’s image on my shirt, has sent me some cat snacks to bring to the Furry Princess (they are unusual—liquid snacks in tubes!). Hili, who’s never had a Japanese cat’s snack, is very excited:

A: Jerry wrote that he is coming with a Japanese treat for you.
Hili: Japanese?!!!
P1040598
In Polish:
Ja: Jerry pisał, że przywiezie ci japońskie jedzenie.
Hili: Japońskie?!!!

And out in Winnipeg, they’ve removed the railings from Gus’s deck, so he has a better view of what’s going on in the yard:

Shhhh. . . .he’s sleeping now. .

German bomber pledges allegiance to ISIS

July 25, 2016 • 1:30 pm

This is a recent report from Reuters:

The Syrian who blew himself up in southern Germany, wounding 15 people, had pledged allegiance to Islamic State on a video found on his mobile phone, the Bavarian interior minister said on Monday.

“A provisional translation by an interpreter shows that he expressly announces, in the name of Allah, and testifying his allegiance to (Islamic State leader) Abu Bakr al-Baghdadi … an act of revenge against the Germans because they’re getting in the way of Islam,” Joachim Herrmann told a news conference.

“I think that after this video there’s no doubt that the attack was a terrorist attack with an Islamist background.”

Islamic State claimed responsibility for the attack, according to Amaq, a news agency that supports Islamic State.

The attack, outside a music festival in Ansbach, a town of 40,000 people southwest of Nuremberg that has a U.S. Army base, was the fourth act of violence by men of Middle Eastern or Asian origin against German civilians in a week.

The man, whose name wasn’t given, is apparently a refugee who arrived in Germany from Syria two years ago, had repeated run-ins with the cops, and was reportedly facing deportation to Bulgaria.

Ray Comfort’s new film “The Atheist Delusion”

July 25, 2016 • 12:45 pm

Ray Comfort’s last movie, “Evolution vs God” (you can see the whole 38-minute movie here), was execrable: Comfort ran around asking people whether they ever saw evolution in “real time,” and if they didn’t he said, “Aha, evolution doesn’t work!”. The trick, of course, that these people, who weren’t scientists, had to give some “observable” evidence, and stuff like fossils or the evolution of insecticide resistance were ruled out tout court. He wanted observations of changes “between kinds”, with “kinds” not defined, as it never is. (See my critique here.)

Now the old goddy has a new film, “The Atheist Delusion”, that opens on Friday. Here’s the trailer:

Over at The Friendly Atheist, Hemant conducted an email interview with Comfort about the movie, which isn’t that enlightening because Comfort refuses to say what that “irrefutable evidence” is that makes atheists squirm and question their nonbelief. The only time they even discuss it is this:

FA: Conservative columnist Matt Barber wrote of this film that, “you managed, in about an hour, to make the case, beyond any reasonable doubt, for the Creator God.” How is it possible that you did that when so many Christian apologists before you have failed?

RC: I wouldn’t say that they failed. They perhaps just didn’t frame it using the Socratic Method. But the question I ask in the movie isn’t a magic bullet. I hope this doesn’t sound offensive, but it only works with those who are both humble and open to reason. I’m sure the movie will be thoroughly trashed by most in the atheist community, but I believe those who want to know the truth will hit it head-on.

I’m curious what this magic bullet really is, but I ain’t gonna pay good money to see the movie. Comfort does note that the movie will be free on YouTube at the end of September. I suspect we’ll all just wait for it. However, one commenter at Hemant’s site says this:

. . . as seen in this meme Ray claims he has one “scientific” question that will destroy atheism. That question is about the existence of DNA. Just marketing hype for his Christian followers. They are the true target of his videos and books. He makes his money from them.

One note: Comfort admits that he was “very embarrassed” by the infamous banana video in which Comfort touts the (domesticated) banana as evidence for God’s handiwork. (He called the banana “the atheist’s nightmare!)

Classic story revised: lichens are fungus + algae + yeast (another fungus)

July 25, 2016 • 11:00 am

One of the classic stories of biology, taught to virtually every student, is the fact that what we call “lichens” are actually a combination of two very distantly related species: a species of alga and a species of fungus. (Sometimes the “alga” is really a species of cyanobacteria, formerly called “blue green algae” but not really algae.) It is offered as the paradigm of a true symbiosis, in which two species living together each provide something for the other. In the case of lichens, the alga provides the products of photosynthesis as nutrients, while the fungus provides structure, protection, nutrients, and moisture.  They’ve coevolved to the extent that while the algal partner can sometimes be found living freely on its own, the fungus is never found on its own. Finally, most (but not all) of the fungal partners in a lichen are ascomycetes (“sac fungi”)—a phylum in the fungal kingdom.

Lichens vary tremendously in their growth form depending on the partners; here are three examples taken from the Wikipedia article:

Letharia_vulpina_JHollinger_crop

N2_Lichen

Parmotrema_tinctorum_umenokigoke01

Well, this classic story has just been revised in a new online paper in Science by Toby Spribille et al. (reference below; free download). Spribille and his colleagues note that although this partnership has been described for decades, attempts to reconstruct a lichen in the lab by combining the fungal and algal partner always failed: researchers could simply not obtain the characteristic structure seen in nature. Their new paper gives an astounding result that may explain this failure: there’s a third partner in this symbiosis, and it’s yet another fungus—a yeast, which is a “basiodiomycete”, a different phylum that includes mushrooms and puffballs.

I’ll be brief.  Spribille et al. discovered the new partner when studying two lichens that looked very different (one produced an acid that made it yellow), but turned out to have the same algal and fungal partners. They were, in effect, the same species of lichen (though of course species delineation is tricky in this group). Why were they so different? They decided to study gene expression in the two forms using genes identified in ascomycetes and algae. No differences were found. But when they expanded their search to other types of fungi, they found that some basidiomycete genes were expressed in one form but not the other, even though no basidiomycetes were supposed to be there.

They then determined that other lichens also had a third basidiomycete partner, but one that differed among lichen “species”.  Although only 42 of the 56 sampled lichen genera had related basidiomycetes (indicating that the partnership may not be required in all lichens), they conclude that “basidiomycete fungi are ubiquitous and global associates of the world’s most speciose radiation of macrolichens.”

Finally, they visualized the cells, which was hard to do because they’re sparse and embedded in the lichen cortex (its skin). They finally managed to visualize the yeast cells, at first detected only by their gene transcripts, by “FISH” (fluorescent in situ hybridization) analysis: making RNA transcripts of the yeasts that hybridized to fluorescent molecules. And then they could see this:

F3.large
Figure from paper. (A) B. fremontii, with (B) few FISH-hybridized live yeast cells at the level of the cortex. (C) B. tortuosa, with (D) abundant FISH-hybridized cortical yeast cells (scale bars, 20 μm).

The previous failure to detect the presence of another fungal partner may explain why scientists haven’t been able to synthesize lichens from their components: they were leaving out the third partner. 

And why wasn’t this partner detected before? The authors suggest that the genes in the new partner simply weren’t detected in the usual gene-sequencing procedures, which can be biased toward detecting genes present in greater numbers.

This shows that long-established stories can be drastically revised by new findings, and that the classic tale of this symbiosis may have to be revised a bit. It remains to be seen whether this new, third partner is actually required for the lichen to form, and, if so, if it really partakes in a symbiosis as well, giving stuff to its two partners and getting back from them. It could even be parasitic or neutral, or have a symbiosis with one of the two other partners and a different relationship with the other. To add the classic ending to scientific papers, “Much work remains to be done.”

Cowardly University of Cape Town panics, disinvites speaker who published the Danish “Mohammed” cartoons

July 25, 2016 • 9:30 am

Last year writer and broadcaster Kenan Malik was invited to the University of Cape Town in South Africa to deliver the T. B. Davie Memorial Lecture, an annual talk devoted to “academic and human freedom.” Malik’s talk, “Free speech in an age of identity politics,” was a spirited defense of untrammeled free speech, and included passages like this:

. . . we can see how in the marriage of identity politics and the therapeutic society, the very character of free speech has become transformed. In a world in which many reject the possibility – indeed the desirability – of common values and goals; in which the prospects of fundamental social transformation seem to have ebbed away; in which societies have become more fragmented and identities more parochial; in which words can appear not as a means through which to find our common humanity but as constant threats to our self-identity; in which there is a tendency to deprecate the idea of moral autonomy and to view the human individual as vulnerable and damaged and in need of protection – in such a world, it is not difficult to see how censorship, the means through which to restrain the power of words, can become transformed into a good.

. . . It is precisely because we do live in plural societies that we need the fullest extension possible of free speech. In plural societies, it is both inevitable and important that people offend the sensibilities of others. Inevitable, because where different beliefs are deeply held, clashes are unavoidable. Almost by definition such clashes express what it is to live in a diverse society.   And so they should be openly resolved than suppressed in the name of ‘respect’ or ‘tolerance’.

And important because any kind of social change or social progress means offending some deeply held sensibilities. Or to put it another way: ‘You can’t say that!’ is all too often the response of those in power to having their power challenged. To accept that certain things cannot be said is to accept that certain forms of power cannot be challenged. Human beings, as Salman Rushdie has put it, ‘shape their futures by arguing and challenging and saying the unsayable; not by bowing their knee whether to gods or to men.’

Good stuff! Unfortunately, Malik’s message was firmly repudiated by the University’s treatment of his successor, Flemming Rose, invited to give the 2016 Davie Memorial Lecture. Rose was the cultural editor of the Jyllands Posten, the Danish magazine that published the well known “Mohammed Cartoons” that enraged all Muslims and brought many newspapers to their knees, fearful of even showing the cartoons because of possible violent reprisal from offended Muslims. (Yale University Press even published a book about the cartoons without showing any of them! You can see them at the Wikipedia link in this paragraph.) Rose is now the foreign affairs editor of the same magazine.

After the University invited Rose to come, they started to have second thoughts. They have now withdrawn the invitation, with the rationale given in a July 12 letter written by the University’s Vice Chancellor, Dr. Max Price, to the Academic Freedom Committee (copy here). The letter is a masterpiece of evasion, cowardice, and duplicity.  As Price says at the beginning of his pusillanimous screed:

No freedom, however, is unlimited. As with all rights, context and consequence are also critical. The right to academic freedom is fundamental, but cannot be exercised in a vacuum. We have a responsibility to exercise this right with due, thoughtful consideration of other equally important rights, and the possibility of other harmful consequences. Indeed, in terms of our Constitution (as in all modern democratic constitutions), every right is subject to limitation by law of general application which complies with a number of requirements, the most significant of which is that the limitation must be proportional to the context in which it operates, and to the impact which its exercise will have on those affected by its exercise.

And then Price lists the harms that would happen to his University were Rose allowed to speak. A brief excerpt from Price’s letter follows; the words are his but where there are ellipses I’ve left out some text for brevity:

1. Provoking conflict on campus. Public order on many campuses is in a fragile state and in some cases volatile. It would be ill-advised to add a highly contentious speaker to the mix at this time. Our consultations have convinced us that bringing Mr Rose to UCT would generate widespread protest and disruption. Mr Rose is regarded by many around the world as right wing, Islamophobic, someone whose statements have been deliberately provocative, insulting and possibly amount to hate speech, and an editor of a “Our Mission is to be an outstanding teaching and research university, educating for life and addressing the challenges facing our society.” publication that many believe took a bigoted view of freedom of expression. . .

2. The security risks of presenting the lecture. The rise of Islamophobia, the undeniable turmoil in the Middle East in general, the Palestinian question, the rise in extremist terrorist groups, and the violent consequences of these factors in the world (including West and East Africa) is the context in which one must consider the consequences of hosting Mr Rose. In particular, the reality of the rise of extremism in almost every established religion, has made the selective defence of blasphemy particularly hazardous and provocative, probably even more so than when the cartoons were originally published. . . . Mr Rose is seen by many as a persona non grata and while most would protest peacefully against him, we believe there is a real danger that among those offended by the cartoons, an element may resort to violence. We are convinced his presence at this time would lead to vehement and possibly violent protest against him and against UCT.

3. Bringing this speaker to deliver the TB Davie lecture in the current environment might retard rather than advance academic freedom on campus. Everyone is deeply aware of the very testing circumstances that pertain to freedom of expression about controversial ideas in this country at present, particularly on university campuses. Our campuses have become charged spaces, in which ideological and social fault-lines have become intensely politicised, sometimes violently so. We are committed to weathering these storms in ways that acknowledge and protect the need for safe spaces to confront and debate such matters. We know that many within our universities don’t feel safe to engage, which undermines the spirit of mutual tolerance and understanding. This is a deeply worrying situation which all adherents of academic freedom should find disconcerting, and ultimately unacceptable. Academic freedom cannot survive, let alone flourish, in such an atmosphere. But will progress on this issue be advanced by inviting someone who represents a provocatively – potentially violently – divisive view to make the case for a considered version of academic freedom that is avowedly sensitive to the concurrent rights to dignity and freedom from harm?

This is all (pardon my French) bullshit. What they have done is consult people after the invitation was issued, only to find—surprise!—that Rose’s actions were controversial.  What that means is that many Muslims didn’t like them and, in fact, killed some people in response. Price, afraid of controversy or Muslim extremist response on his campus, and completely disregarding what Malik said the year before, decided to avoid possible violence or controversy by disinviting Rose. The last bit—the claim that inviting Rose would hinder rather than advance academic freedom—is pure Orwellian doublspeak. How does it advance that freedom by disinviting a “provocative” speaker? Vice-Chancellor Price should be ashamed of himself.

But the best takedown of the University and Price’s letter was by Malik himself, in a piece at his website Pandaemonium called “Academic freedom and academic cowardice.” It’s a devastating indictment of the cowardice of the disinvitation, which does amount to censorship, and I’ll give just the last paragraphs (note: Malik was born in India but moved to England at a young age):

Does the UCT executive really believe that the preservation of academic freedom requires it to invite only those speakers who cause no provocation or raise tension? Does it imagine, in other words, that one can only preserve academic freedom by inviting speakers with whom the audience is likely to agree? In which case, what is the point of such speakers speaking?

In disinviting Flemming Rose because some condemn him as offensive or Islamophobic, the UCT executive is not only undermining academic freedom, it is also blindly entering a fraught debate within Muslim communities – and supporting the conservatives against the progressives. What is called ‘offence to a community’ is more often than not actually a struggle within communities. There are hundreds of thousands, within Muslim communities in the West, and within Muslim-majority countries across the world, challenging religious-based reactionary ideas and policies and institutions. There are writers, artists, political activists, daily putting their lives on the line in facing down blasphemy laws, standing up for equal rights and fighting for democratic freedoms; people like Sabeen Mahmud, the Pakistani rights activist shot dead last year by religious militants; or Bangladeshi bloggers such as Nazimuddin Samad and Avijit Roy, hacked to death for their blasphemies; or Raif Badawi, the Saudi blogger senstenced to seven years’ imprisonment and a thousand lashes for ‘insulting Islam’. Such issues are live in South Africa, too. Last year, the writer ZP Dala was violently assaulted in Durban for expressing her admiration of Salman Rushdie, and subsequently forced by the local community into a mental hospital, apparently to cure her of her blasphemous views. For such figures a ‘safe space’ means not a place in which to hide from unpalatable ideas, but a space in which their lives are not threatened. Every time an institution such as UCT attempts to censor a speaker for ‘giving offence’ or for their ‘blasphemous views’, it betrays the struggles of those such as Sabeen Mahmud, Nazimuddin Samad, Avijit Roy, Raif Badawi and ZP Dala.

That’s just damn eloquent.

I’ve written to Vice Chancellor Price, whose cowardly letter was dated July 12 of this year, and if you wish to make your views known, his address is public; you can find it on the letterhead here.
