Quolls!

As a special 5000th-post-day present to you all, here are some True Facts About the Quoll. How can you resist an animal called a quoll? The quoll – a carnivorous marsupial – is about the size of a cat, and apparently occupying a similar niche in Australia. Here’s one:

This quoll is spotted – hence its name, Dasyurus maculatus. For reasons best know to Aussies, it used to be called the Tiger Cat. The spotted tail quoll (above), Dasyurus maculatus maculatus, is found in eastern Australia, down to Tasmania, mainly in rainforest and wet forest. Another subspecies lives in northern coastal regions.

Quolls are currently endangered because of habitat fragmentation (which includes its den sites), competition from feral mammals and its unfortunate habit of eating cane toads, a giant introduced species that is poisonous. Conservationists are trying to condition the quolls not to eat cane toads.

Quolls prey on birds as well as toads, and will fight with the extremely scary Tasmanian Devil over food. They are nocturnal (hence the spots, I would guess) and will utter a very scary piercing scream if disturbed. (Photos from ARKive):

They have two colour phases – ginger/brown (above) and black:

Here’s a video of someone bottle feeding a baby spotted tail quoll:

There is another quoll, the Eastern Quoll (Dasyurus viverrinus), which now appears to be limited to Tasmania. You can find more about the last mainland Australian sightings of the Eastern Quoll here. Here’s a video of an Eastern Quoll, complete with inappropriate music:

There is also a Northern Quoll, Dasyurus hallucatus. And the compass being what it is, there is also a Western Quoll called a Chudditch. Here’s a baby Chudditch:

There are also two species of quoll found in New Guinea – the New Guinea Quoll and the Bronze Quoll.

Quolls do not have pouches like a kangaroo, but an area of skin around the teats grows to create a flap of skin that contains the young. To tell the reproductive status of a female quoll, you  look into the ”pouch”. In the follicular phase, the area turns red, while post-ovulation it becomes wet and deep. This is also true of the Tasmanian Devil, though probably a bad idea, as the Devil has Very Big Teeth. This abstract describes the procedure in more detail… I wouldn’t try it at home, though.

If you’re in Australia and spot a quoll (or want to!), go here.

Jehovah’s Witnesses and blood transfusion

March 1, 2013 • 9:15 am

I had forgotten that the Jehovah’s Witnesses (JW) forbid blood transfusions, but this article in last Sunday’s New York Times reminded me. It’s about physicians who are performing bloodless operations to accommodate the JWs who can’t receive blood.

The piece starts with the tale of Rebecca Tomczak, a JW who needed a lung transplant because her own lungs had been destroyed by the disease sarcoidosis. After shopping around, she finally found a hospital that would operate on her without giving her extra blood.

The article discusses the refusal of JWs to accept blood, a stand that is, of course, based on scripture:

The reason: Ms. Tomczak, who was baptized at age 12 as a Jehovah’s Witness, insisted for religious reasons that her transplant be performed without a blood transfusion. The Witnesses believe that Scripture prohibits the transfusion of blood, even one’s own, at the risk of forfeiting eternal life.

. . .in April, on a trip to the South Carolina coast, she found that she was too breathless to join her frolicking grandchildren on the beach. Tethered to an oxygen tank, she watched from the boardwalk, growing sad and angry and then determined to reclaim her health.

“I wanted to be around and be a part of their lives,” Ms. Tomczak recalled, dabbing at tears.

She knew there was danger in refusing to take blood. But she thought the greater peril would come from offending God.

“I know,” she said, “that if I did anything that violates Jehovah’s law, I would not make it into the new system, where he’s going to make earth into a paradise. I know there are risks. But I think I am covered.”

. . . Founded in the late 19th century and best known for door-to-door evangelism, the Jehovah’s Witnesses first published a position on transfusions in 1945, as the blood donation system expanded after World War II. It grew out of edicts in both the Old and New Testaments that forbid the consumption of blood, which is revered as a life source. The church, based in Brooklyn, takes the position that there is no distinction between oral consumption and intravenous feeding.

The Witnesses’ hard line does have its soft spots. The church declared in 2000 that it was up to members to decide whether to accept blood fractions like clotting factors that are extracted from plasma. It has also left to individual conscience whether to accept synthetic proteins that stimulate red cell production or to use mechanical techniques that conserve and salvage blood.

Here’s the scripture from Wikipeda (which has a long article about the practice), and the doctrine based on it. If you get a transfusion as a JW, you get shunned (unless you “repent”):

Based on various biblical texts, such as Genesis 9:4, Leviticus 17:10, and Acts 15:29, they believe:

  • Blood represents life and is sacred to God. After it has been removed from a creature, the only use of blood that God has authorized is for the atonement of sins.When a Christian abstains from blood, they are in effect expressing faith that only the shed blood of Jesus Christ can truly redeem them and save their life.
  • Blood must not be eaten or transfused, even in the case of a medical emergency.
  • Blood leaving the body of a human or animal must be disposed of, except for autologous blood transfusions considered part of a “current therapy”.
  • A baptized Witness who unrepentantly accepts a blood transfusion is deemed to have disassociated himself from the religion by abandoning its doctrines and is subsequently subject to organized shunning by other members.

Here are the sections from Acts 15 (the passages cited most often by JWs to support their position) are used to prohibit transfusion (all passages below from King James Version):

19 Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God:

20 But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.

. . . 29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.

Leviticus 17:10:

And whatsoever man there be of the house of Israel, or of the strangers that sojourn among you, that eateth any manner of blood; I will even set my face against that soul that eateth blood, and will cut him off from among his people.

Genesis 9:4

 But flesh with the life thereof, which is the blood thereof, shall ye not eat.

There’s one upside to all this: because of the cost of blood, and rare negative effects of transfusion, surgeons are developing ways to operate without the need for extra blood. The Times reports:

The latest government data show that one of every 400 units transfused is associated with an adverse event like an allergic reaction, circulatory overload or sepsis [JAC: note that those reactions are probably not always fatal]. Even so, the share of hospital procedures that include a transfusion, usually of two or three units, has doubled in 12 years, to one in 10.

Yet at dozens of hospitals with programs that cater to Jehovah’s Witnesses, a million-patient market in the United States, researchers have found that surgical patients typically do just fine without transfusions.

“They are surviving things that on paper were not expected to go well at all,” said Sherri J. Ozawa, a nurse who directs the long-established bloodless medicine program at Englewood Hospital in New Jersey.

The economy is also helping the blood management movement. Processing and transfusing a single unit of blood can cost as much as $1,200, and many hospitals are trying to cut back.

Well, that’s the good part, I suppose, but the bad part is this:

Unlike other patients, Ms. Tomczak would have no backstop. Explicit in her understanding with Dr. Scheinin was that if something went terribly wrong, he would allow her to bleed to death. He had watched Witness patients die before, with a lifesaving elixir at hand.

In addition, as the National Post reports, Jehovah’s Witnesses have fought to keep their children from getting transfusions (they lose in Canada; I’m not sure about elsewhere), but many members have died because of this policy. The Independent recounts one in a story from last year called “Lawyers tell of agonizing scenes as doctors forced to let Jehovah’s Witness, who wanted to live, die.:

Robert Tobin, a partner in the London law firm Kennedy’s, was called in by an unnamed NHS Trust when the man, a Jehovah’s Witness who was critically ill with sickle cell anaemia, refused a blood transfusion which could have saved his life.

Over three weeks the man gradually deteriorated as the crisis progressed, before eventually dying.

“Medical staff were understandably upset at seeing a patient deteriorate before their eyes knowing a simple procedure could have been provided that would have saved his life,” Mr Tobin said.

The man’s mother, also a Jehovah’s Witness, was at her son’s bedside, and an elder from the man’s church also attended. The trust was concerned that they were unduly influencing him but a doctor from a neighbouring trust who was called in to assess him said he had full capacity and was making the decision on his own.

Yes, there are down sides to transfusion, but shouldn’t people have the option of weighing the risk of bleeding to death against the 1/400 chance of an adverse reaction per unit of blood? After all, at present not all surgeries can be “bloodless”, and if you die from refusing blood you leave behind grieving family and friends—all in service of a bizarre interpretation of a work of fiction.

My 5000th post: Henri sells out

March 1, 2013 • 5:50 am

I had hoped to post something a bit more weighty than this for post #5000 (it’s been a good run, I think), but I suppose the combination of cats and unbridled capitalism is appropriate.  So, on to Henri, the formerly existentialist cat. . .

It was too good to be true. Along with Henri’s latest (and shortest) YouTube video, we have this notice:

Henri has been commissioned by Friskies to explore the phenomenon of cat food boredom, for the benefit of all catkind. This disappointment will not stand. Look out for Part 2, coming very soon.

And, sure enough, Henri suggests here that feline ennui might be dispelled by. . . Friskies!  He’s even shown with the huge Friskies gift basket that induced him to sell out (I presume his owner gets a nice dollop of cash as well).  There will apparently be four of these videos. Oy vey. Watch and weep:

I’m not a big fan of Friskies, and didn’t feed it to my cat. If you look at the ingredients in a typical can, it contains a lot of grains and “meat by-products.” In contrast, a high-quality wet food, like Core Grain-free Food, contains real meat (not “meat by-products) and no grains. (Go here for a good guide to cat nutrition.)

Would Jean-Paul Sartre, were he here today, make commercials for McDonald’s?

Beautiful, brutal ctenophores

February 28, 2013 • 11:54 am

by Matthew Cobb

Ctenophores (“teen-o-forz”), or ‘comb jellies’ are some of the most beautiful organisms in the ocean. They are generally transparent, and biradially symmetrical, so they have infinite planes of rotational symmetry. As if that wasn’t enough, they have beautiful ‘combs’ along their edges, which shimmer in the light as they move the animal around, using simple muscle cells. This gives you an idea of how beautiful they are:

comb jelly

Their prey, however, may not find them so beautiful, and their eating habits are anything but elegant. Here’s a video of ctenophores (Bereo ovata, apparently) just swallowing other ctenophores (Mnemiopsis macrydi). The mouth on the first snarf looks so human-like I wondered if it wasn’t CGI, but it isn’t. It’s just life in all its gory glory:

Ctenophores are not jellyfish. They don’t sting and they are never colonial organisms. Strikingly, they have a peripheral nerve net and can respond to gravity and perhaps light. This video filmed in the Arctic sea off Svalbard in Norway shows that they can separate the wheat from the chaff when it comes to eating their prey:

True facts about the ctenophores:

• 150-200 species

• Found at a range of depths

• Grow from 2mm – 2m in size

• They have a mouth at one end, and an apical sense organ at the other

• They have a blind gut (which you can see on these videos)

• They eat zooplankton, small fish, and even ctenophres

• They are selfing hermaphrodites (ie they do it with themselves)

• The fertilized eggs are released into the water and develop into mini-adults in 24 hours

In 2008, a paper in Nature suggested that the ctenophores might be on a different branch of life from the rest of the animal kingdom. However, they authors themselves said:

The placement of ctenophores (comb jellies) as the sister group to all other sampled metazoans is strongly supported in all our analyses. This result, which has not been postulated before, should be viewed as provisional until more data are considered from placozoans and additional sponges. If corroborated by further analyses, it would have major implications for early animal evolution, indicating either that sponges have been greatly simplified or that the complex morphology of ctenophores has arisen independently from that of other metazoans.

Nature 452, 745-749(10 April 2008)

An initial study of the first ctenophore genome to be sequenced Mnemiopsis leidyi (a close relative of the victim in the video above) suggested that sponges and ctenophores first branched off from the rest of the animal kingdom (Ryan et al, 2010):

Tree

Joseph F Ryan, Kevin Pang, James C Mullikin, Mark Q Martindale, and Andreas D Baxevanis (2010) The homeodomain complement of the ctenophore Mnemiopsis leidyi suggests that Ctenophora and Porifera diverged prior to the ParaHoxozoa EvoDevo. 2010; 1: 9.

Andrew Sullivan suspects that Pope Benedict is gay

February 28, 2013 • 11:36 am

Andrew Sullivan, gay activist, staunch Catholic, and blogger, has a pretty incendiary post up at The Dish.  I reproduce part of it without comment, except to say that someone who is gay is more likely to be an accurate detector of gay behavior:

But this is what really made me sit up straight, so to speak:

Benedict’s trusted secretary, Monsignor Georg Gänswein, will be serving both pontiffs — living with Benedict at the monastery inside the Vatican and keeping his day job as prefect of the new pope’s household. Asked about the potential conflicts, Lombardi was defensive, saying the decisions had been clearly reasoned and were likely chosen for the sake of simplicity. “I believe it was well thought out,” he said.

So Benedict’s handsome male companion will continue to live with him, while working for the other Pope during the day. Are we supposed to think that’s, well, a normal arrangement? I wrote a while back about Gänswein’s intense relationship with Ratzinger, while noting Colm Toibin’s review of Angelo Quattrochi’s exploration of Benedict, “Is The Pope Gay?”. Here’s Toibin getting to some interesting stuff:

Gänswein is remarkably handsome, a cross between George Clooney and Hugh Grant, but, in a way, more beautiful than either. In a radio interview Gänswein described a day in his life and the life of Ratzinger, now that he is pope:

The pope’s day begins with the seven o’clock Mass, then he says prayers with his breviary, followed by a period of silent contemplation before our Lord. Then we have breakfast together, and so I begin the day’s work by going through the correspondence. Then I exchange ideas with the Holy Father, then I accompany him to the ‘Second Loggia’ for the private midday audiences. Then we have lunch together; after the meal we go for a little walk before taking a nap. In the afternoon I again take care of the correspondence. I take the most important stuff which needs his signature to the Holy Father.

When asked if he felt nervous in the presence of the Holy Father, Gänswein replied that he sometimes did and added: ‘But it is also true that the fact of meeting each other and being together on a daily basis creates a sense of “familiarity”, which makes you feel less nervous. But obviously I know who the Holy Father is and so I know how to behave appropriately. There are always some situations, however, when the heart beats a little stronger than usual.’

This man – clearly in some kind of love with Ratzinger (and vice-versa) will now be working for the new Pope as secretary in the day and spending the nights with the Pope Emeritus. This is not the Vatican. It’s Melrose Place.

I have no idea whether Sullivan’s suspicions are correct, and, of course, there’s nothing wrong with being gay. But there is something wrong— something deeply hypocritical—about being gay and, at the same time, helping lead an institution that condemns gays and sees gay behavior as sinful acts of “grave depravity” and as “intrinsically disordered.” We already know that many members of the Catholic hierarchy who condemn gays nevertheless engage in that behavior (or in child rape) themselves.

At any rate, Benedict will be Pope Emeritus as of this evening.

_______

p.s.  In today’s New York Times, theologian and author Hans Küng outlines what kind of Pope the Catholic Church needs. Hint: one who does not espouse medieval theology like Benedict did.

Squirrel report

February 28, 2013 • 8:49 am

There are actually two squirrels involved in building the nest on my office windowsill, so I have hopes for a brood of babies later this spring. In the meantime, twigs continue to accumulate and, as per Ben Goren’s suggestion, I have cut up strips of soft, clean socks for them to use as nesting material.

At the moment I have only peanut butter to feed them, and I understand the problems with this food, but I’m going to buy some seeds and nuts in the next few days.

Here’s their current situation (a dollop of Skippy on the right).
