A few random photos from Lisbon

October 10, 2012 • 9:54 pm

I leave this morning for Vienna: other skies, other fudz.  My best photos of Portugal—the ones of the Douro valley—will have to wait until I have more time to post. But here are a few photos I took while wandering around Lisbon yesterday.

This is neither a good nor a flattering photo, but I was in the Museo do Design e da Moda (the design and fashion museum), which highlights triumphs of good design (modern furniture, the Vespa, nice clothing), and I saw the smallest car I’ve ever seen. I put myself into the photo for scale. It’s much smaller than a SmartCar, and I think it’s a BMW. But I’m sure some reader will know it, so please identify it.

After I took the photo I was told that photography was prohibited, but the deed was done. (Click all photos to enlarge.)

Upstairs was an exhibit of theater and music from Brazil, with a guest book that one could sign. The signatures were, as you might expect, very artistic, and although I’m not an artist I had to add mine:

And “beware of the dog” and “here is the cat” signs for sale in a sign store. It is Basement Cat, but note that you needn’t be afraid of him!

Yesterday’s lunch

October 10, 2012 • 12:30 pm

I’m not generally fond of eating cephalopods, but I was told many times that the Portuguese really know how to cook octopus. So when I went to lunch yesterday with my Portuguese publisher, I broke down and ordered the restaurant’s speciality—octopus, oven-roasted with garlic and olive oil:

It was spectacularly delicious, crunchy on the outside, meaty on the inside, and with a delicious mild flavor accented by lashings of garlic.  If Americans could cook octopus like this I’d eat it all the time!

Conspiracy road trip with creationists: Noah’s Ark and other LOLz

October 10, 2012 • 6:52 am

A few months ago the British film company Renegade Pictures flew me to Arizona, where I was to take on five British fundamentalist creationists (four Christians, one Muslim) as part of the “Conspiracy Road Trip” t.v. series. Three of these hour-long episodes have appeared or will appear on BBC3 television: one on UFOs (to come), one on the London 7/7 bombings, and the show I helped with—the one on creationism.

I was part of a group of scientists, including Don Prothero, Gregg Wilkerson, Michael Russell, and Tim White, chosen to participate in “Conspiracy Road Trip: Creationism.” The hope was, I guess, to try to change the mind of these diehard British creationists (Brits, if you don’t think they exist in Old Blighty, just watch this hour-long episode!) and bring them around to accepting evolution.

When I was asked to participate, I replied there wasn’t a snowball’s chance in hell of real young-earth creationists coming around to Darwinism, but I went along for the fun of it.

My assigned task was to debunk the myth of Noah’s Ark, which I was supposed to do while floating on a boat on Lake Powell. That would seem to be an easy task, but not if you’re facing five people whose whole worldview would crumble if they didn’t see the entire Bible (or, for Abdul, the Qur’an) as literally true.

Anyway, the host, Irish comedian Andrew Maxwell, was an engaging guy with a deep respect for science as well as the ability to move things along and get a group of the faithful with a chip on their shoulders to talk to a group of deeply suspicious scientists. Here’s the Renegade Pictures blurb:

Comedian Andrew Maxwell takes 5 British Creationists to the West Coast of America, to try to convince them that evolution is true and their ideas are, well, crackers.  Stuck on a bus across 2,000 miles of dustbowl roads with these religious fundamentalists, Maxwell tackles some mind-boggling ideas.  Could the Earth be only 6,000 years old, did humans and T-Rex live side by side?  It’s a bumpy ride, as he’s confronted with some very unchristian behaviour along the way, but by the end could he possibly win over any of the Bible-bashers with hard scientific fact…. And keep a straight face?

I think I posted on this before the program came out, but this is just the second day the program’s been available, and the first time I’ve seen it. Enjoy the video below (I appear about 12 minutes in):

(I’m told that Brits can’t access this, but maybe there’s another link that a reader can find. Maybe this one will work.)

Young-earth creationists are almost all intransigent, be they British or American. It’s just ineffably sad to see a group of intelligent young people so readily reject the evidence of their senses. And note this as well—who are the militant ones here: the creationists or the scientists?

Andrew started this trip with high hopes, but you can see his increasing frustration, and his abandonment of “objectivity”, as the program proceeds. I could have predicted that.

After watching this show, I see it more as a sociological document—as a collision between incompatible cultures—than as a show about evolution.  If you maintain that science and faith are compatible, you’ll have to rule out these five creationists as practicing “true” religion. That’s what Steve Gould had to do to prop up his NOMA hypothesis that true religion is compatible with true science.

To see the real creationist mindset and the cognitive dissonance it inspires, listen to the dialogue between JoJo and Bronwyn starting at 47 minutes in.

In the end, JoJo, with whom I had a really nice one-on-one conversation on the boat (I’m sending her my book), was the only person who budged even a millimeter when given the evidence for evolution. If you can face the row of skulls that Tim White set up, and pretend that they don’t show evolution, you’re hopeless. (Look at Abdul’s ridiculous response.)

Nobel Prize for Chemistry

October 10, 2012 • 5:51 am

by Matthew Cobb

The third of the Nobel science awards was announced this morning – it went to two US scientists, Robert J Lefkowitz and Brian K Kobilka, for their work on G-protein coupled receptors. For once, I actually understand some of the science involved. G-protein coupled receptors are a particular kind of cellular receptor that enable us to respond to a wide range of stimuli, including odours (which is why I understand this stuff). Lefkowitz (left) works at  the Howard Hughes Medical Institute and Duke University, Durham, North Carolina, while Kobilka (right) now works at Stanford. Lefkowitz began work on the beta-adrenergic receptor in 1968 and Kobilka joined him in the 1980s; as the Nobel Citation puts it:

The studies by Lefkowitz and Kobilka are crucial for understanding how G-protein–coupled receptors function. Furthermore, in 2011, Kobilka achieved another break-through; he and his research team captured an image of the β-adrenergic receptor at the exact moment that it is activated by a hormone and sends a signal into the cell. This image is a molecular masterpiece – the result of decades of research.

The earliest receptors to have evolved will have worked by the stimulus (or ‘ligand’) directly opening or closing pores in the membranes of the earliest cells. This will have enabled single-celled organisms to migrate up chemical gradients in the primeval sea. Over evolutionary time, receptor mechanisms became much more complex, and many of the key receptors in your body involve a cascade of biochemical interactions, which begin when a receptor molecule (generally a snake-shaped molecule which wiggles in an out of the membrane) detects the stimulus. The change in the shape of the receptor molecule activates the associated ‘G-protein’, which is inside the cell and has three sub-units. Changes in the sub-units can then activate other proteins, enabling the cell to respond appropriately, by changing its internal environment, or, in the case of a neuron, by allowing ions to enter, thereby producing a neuronal response.

The amazing complexity of the G-protein coupled cascade – which no designer would ever build – shows the truth of Jacob’s aphorism that evolution doesn’t design, it ‘tinkers’. To give you some idea of what’s happening – all in the space of milliseconds – here’s a video:

 

 

WEIT available in the UK via Kindle

October 10, 2012 • 1:31 am

Alert reader Michael informs me that WEIT is now available (OUP version) on Kindle in the UK. Amazon.co.uk has it for £5.79.

I was amused to see that you can also buy this book too, and for only two pounds 61 pence:

Here’s an excerpt:

Nierode’s Ph.D. is in engineering, of course, and the title means that I have my very first “flea”! I love the picture of The Origin shaking hands with the Holy Bible, which is ludicrous given that Nierode is a Biblical literalist.

Although several readers have inquired, I still don’t know whether WEIT is available on Kindle in Australia.

Beluga whales to be captured, jailed

October 10, 2012 • 12:08 am

In 1991, the Chicago Tribune wrote an editorial supporting the acquisition of more beluga whales from the wild for exhibit at the local Shedd Aquarium, and criticized animal-rights activitists who were opposing this plan. (Belugas, Delphinapterus leucas, are social mammals found in Arctic and sub-Arctic waters.)

I wrote a letter to the editor opposing this capture as inhumane, and unlikely to add anything to our scientific knowledge of the beasts. (I may be wrong, but I don’t think the Shedd has ever published any peer-reviewed scientific papers on their animals). And beluga whales are not legally endangered: since I wrote my letter they’ve been listed as “threatened”,  but that’s because of pollution and hunting, something we don’t need to capture whales to mitigate.

Surprisingly, I found my letter on the internet, which criticized the Shedd’s claim that the whales were okay in their small pools because they didn’t show abnormal behaviors (the quotation marks are from the original editorial, which I couldn’t find on the Web):

Beluga Beings

September 09, 1991|By Jerry Coyne, Associate professor, Dept. of Ecology and Evolution, University of Chicago.

CHICAGO — In dismissing the arguments of animal rights activists who oppose the capture of more beluga whales for the Shedd Aquarium, your editorial (Aug. 29) makes a number of questionable assertions:

“The belugas at Shedd are hardly cruelly confined.” After observing the apparently normal behavior of well-fed prison inmates, a Martian might make similar arguments for confining humans in small cages. My own guess would be that these highly intelligent creatures, which have evolved to roam the open sea, would prefer to be left in their normal habitat.

“Understanding the breeding biology of belugas is important in protecting them in the wild.” Belugas are not endangered, and they are best protected by leaving them alone. If whales become extinct, it will be due to hunting or pollution, not to ignorance about their reproduction. Moreover, breeding biology in captivity may differ profoundly from that in the wild.

“Exposing people to beluga whales increases their sensitivity toward the animals.” It is not clear how such “sensitivity” will help wild belugas. Many well-loved animals, such as elephants and pandas, go extinct not because of a lack of sensitivity, but because of political and economic considerations beyond our control.

As a biologist, my own response is sadness toward humans who feel no compunction at capturing wild whales and exhibiting them for public entertainment.

Some of the activitists picketing the aquarium used phrases from my letters on their signs, and I was criticized by my department for interfering in the Shedd’s affairs. I paid no attention, for humans surely don’t have the right to remove free-ranging and sentient animals from their habitats just for their own amusement, particularly when studying the whales is not really the object.

Well, aquaria are still up to their old tricks: they want to capture more whales, which are a big public draw (they’re white and cute and lucrative), using the excuse of needing to study them in captivity.

In a piece published yesterday by New York Times writer Felicity Barringer, “Strong opposition to aquarium’s plan to import beluga whales,” the Georgia Aquarium is applying for a permit to capture more whales—a lot of them (eighteen!):

The Georgia Aquarium in Atlanta has applied for a federal import permit on behalf of a group of marine parks, saying the aquariums need the Arctic whales for captive breeding efforts, research and education. Approval would end an import hiatus of nearly two decades that is rooted in misgivings about removing intelligent and social marine mammals from their native waters and their families.

Complicating matters, the federal government’s decision will be based not on bioethics but on the language of the Marine Mammal Protection Act, which recognizes a benefit in winning the hearts and minds of paying customers who become attached to animals like the beluga, a facially expressive whale with a distinctive white hue.

Well, that sucks. These whales have no choice about whether they stay in their habitat or are captured (something that really stresses these animals if if you’ve ever seen it) and used to “win the hearts and minds of paying customers.”

In the end, it’s all about money—making these animals into clowns to entertain the public. Believe me, that rakes in the cash, because, at the Shedd, you have to pay extra to see the whales. And it’s not like we can be sure these mammals are happy in their small tanks: they are free-ranging beasts that swim hundreds of miles across open sea and migrate south during summer. That’s where they evolved, and presumably where they’re comfortable.

If you doubt the mercenary motives lurking behind the pretense of science, read this:

At least four of the nation’s largest marine parks, including the Georgia Aquarium, invite visitors to don wet suits and pet or be nuzzled by the animals for $140 to $250. The Shedd Aquarium in Chicago offers couples, for $450, a romantic wading experience that can culminate in a marriage proposal with Champagne, strawberries and the beluga as a de facto chaperon.

Imagine if humans were captured by intelligent extraterrestrial beings, put in cages, and used as accountrements in wedding ceremonies! This practice of my own local aquarium disgusts me. I call on my fellow biologists at the Shedd to stop degrading offers like this.

I’m not the only scientist who objects:

For Hal Whitehead, a marine mammal expert at Dalhousie University in Nova Scotia, there is not much need for debate. “We know that they are intensely social mammals with complex and lengthy migrations, and that they use a whole bunch of different habitats in different times of the year, and that they are acoustic communicators,” he said. “There is no way even the best captive situation has even the slightest approximation to that.” . . .

. . . Lori Marino, a neuroscientist at Emory University who studies whale intelligence, said she saw the aquarium’s main incentive as “to keep people entertained.”

While the acquisition would infuse the captive population with more genetic variety and keep it “going a little while longer,” she said, “there is no scientific purpose.” The Georgia Aquarium and the Utrish Marine Mammal Research Station in Russia, where the belugas are being held, declined to disclose how much the American aquariums had agreed to pay for the whales.

Indeed. Why the secrecy? Could it be because the price is high, and owning the whales so lucrative?

Marilee Menard, the executive director of the Alliance of Marine Mammal Parks and Aquariums, called the imports of belugas “a seminal decision that is strongly supported by the marine mammal community.”

That does not convince Dr. Whitehead, the whale expert in Nova Scotia. In captivity, he said, “many of the processes which are clearly important in the wild can’t flourish, such as the flexible social systems they seem to have, such as the migrations, such as using sounds without having them echoed back at you from concrete a few meters away.”

Other scientists have mixed sentiments, like Robert Michaud, an expert at a conservation group called Gremm in Quebec.

“I can make the case that research on these animals in captivity helps animals in the wild,” said Mr. Michaud, who was hired by the Georgia Aquarium to coordinate research into the beluga populations in the Sea of Okhotsk. “We are still learning things about their biology and behavior.” [JAC: Well, have they published their results? And has that learning helped us conserve them?]

But “you won’t find in me a strong defender of captive animals,” he said.

“You are breaking family groups,” he added. “The pool will never be the open ocean.”

Yes, and if you’ve seen how small the pools are at the Shedd, and how the whales swim around and around in them, endlessly circling, you’d see how cruel this really is.

The beasts can’t speak, so we must speak for them. We do know that, like all cetaceans, they’re intelligent—and these ones are social, forming pods averaging ten members. There’s no way they’re going to replicate their normal lives in aquaria.

The best way to preserve these whales is to eliminate hunting. That’s been done in the U.S., but native North Americans are still allowed to hunt up to 1500 per year in Canada and the U.S., and other countries don’t have such strictures.

We won’t save them by capturing more whales and allowing the public to gawk at them, all the while pretending to study them for conservation purposes. How, for example, are aquaria going to study the effects of pollution on their breeding? That can’t be done. Conducting controlled experiments on animals removed from their native habitat is not only nigh impossible, but captivity may affect their breeding and behavior in ways that can’t be extrapolated to wild populations.

If you want to make your voice heard, and live in the D.C. area, there’s a public meeting for the permit application this Friday  from 2-5 p.m. at the NOAA Silver Spring Metro Center Complex, NOAA Science Center, 1301 East-West Highway Silver Spring, MD 20910, and there’s also a Facebook page. 

I don’t expect the public to have much influence, though. The forces of money, masquerading as attempts at “conservation,” are too powerful.

‘”Nones” on the rise’ in US

October 9, 2012 • 8:46 am

by Greg Mayer

A new study by the Pew Forum on Religion & Public Life reports that the proportion of Americans who do not belong to any particular religion has grown noticeably:

The number of Americans who do not identify with any religion continues to grow at a rapid pace. One-fifth of the U.S. public – and a third of adults under 30 – are religiously unaffiliated today, the highest percentages ever in Pew Research Center polling.

In the last five years alone, the unaffiliated have increased from just over 15% to just under 20% of all U.S. adults. Their ranks now include more than 13 million self-described atheists and agnostics (nearly 6% of the U.S. public), as well as nearly 33 million people who say they have no particular religious affiliation (14%).

This large and growing group of Americans is less religious than the public at large on many conventional measures, including frequency of attendance at religious services and the degree of importance they attach to religion in their lives.

Trend in religious affiliation over time. Data from the General Social Survey. (Figure by the Pew Center, but not from the Pew data, which is for a shorter period (2007-2012), but shows the same trend).

Most news media attention has focused on the fact that Protestants are no longer a majority (for example, at NPR), while mentioning the increase of the unaffiliated as a cause. The “none” are mostly theists of some sort; 68% profess a belief in God in the Pew survey.
