The power of the gut

There’s a short article at Physorg about research into the relation between gut bacteria and the brain (and thereby personality, mental illness, etc.)

Using germ-free mice, Foster's research shows gut bacteria influences how the brain is wired for learning and memory. The research paper has been published in the March issue of the science journal Neurogastroenterology and Motility.

The study's results show that genes linked to learning and memory are altered in germ-free mice and, in particular, they are altered in one of the key brain regions for learning and memory – the hippocampus.

"The take-home message is that gut bacteria influences anxiety-like behavior through alterations in the way the brain is wired," said Foster.

Foster's laboratory is located in the Brain-Body Institute, a joint research initiative of McMaster University and St. Joseph's Healthcare in Hamilton. The institute was created to advance understanding of the relationship between the brain, nervous system and bodily disorders.

"We have a hypothesis in my lab that the state of your immune system and your gut bacteria – which are in constant communication – influences your personality," Foster said.

I can’t help but think of Hitler, who had serious digestive problems all his life. This is from an interesting review of a book on the topic of his health:

Theo Morell, recorded in his diary that after Hitler downed a typical vegetable platter, "constipation and colossal flatulence occurred on a scale I have seldom encountered before."….

Morell's diaries (which were recovered from Germany and are kept in the National Archives in Washington, DC) make clear that the bouts of "agonizing flatulence" remained a regular occurrence.

Although I have noted in a previous post the cocaine eyedrops and methamphetamine that Hitler’s quack doctor Morell prescribed, I am not sure if I read this before:

Morell plied him with a remedy called "Dr. Küster's Anti-gas pills," which contained significant amounts of strychnine--and Hitler often took as many as 16 of the little black pills a day. The sallow skin, glaucous eyes and attention lapses noted by observers later in the war are consistent with strychnine poisoning; another ingredient in the pills, antropine, causes mood wings from euphoria to violent anger.

I see that someone on Yahoo Answers has asked whether Adolf might have suffered from celiac disease (the intolerance to gluten that seemingly has risen sharply – at least in diagnosis – lately.) This seems a pretty good suggestion, actually, especially if (as one person in the answers notes) he was “notoriously fond of cakes and pastries.” I see a source for that is Mental Floss Magazine ( a journal that has escaped my attention til now) blog which says:

In fact, Hitler’s favorite dessert chef, Gerhardt Shtammer, claims that Hitler asked him to make delectable desserts right up to the very end, when they were trapped in Hitler’s bunker with hard-core Nazi holdouts. According to Shtammer, Hitler’s favorite desserts were eclairs decorated with little swastikas and strudel.

Googling "Gerhardt Shtammer" does not come up with any more detail, though. If he lived today, he would have had appearances on Oprah, at the very least.

So, there you go. We can add “cream puffs” to our list of speculations as to the cause of World War II.

Keep counting them

Further in my series of “famous climate skeptic writers who made bad calls on the seriousness of Fukushima,” you can add the Telegraph’s James Delingpole.

This morning, I see that the Japanese PM has said that the situation remains grave and he cannot be optimistic.  (That’s how the ABC is reporting it.)

What I suspect is going on – but could be wrong of course – is that they have realised they have a very dangerous leak of very radioactive water, probably from the reactor core itself, and no one knows how to get rid of it.

Update:   from Bloomberg:

Radiation levels in sea water inside quake-damaged reactors at the Fukushima Dai-Ichi power plant may be rising, Japan’s nuclear watchdog said.  Levels show signs of climbing, Hidehiko Nishiyama, a spokesman at the Nuclear and Industrial Safety Agency, said in Tokyo today. Readings of between 200-300 millisieverts per hour were found in water at the No. 2 reactor, he said, equivalent to the maximum-permitted exposure for workers during the crisis.

I think (although media reporting on this is often mucking up the figures) the anuual limit for US reactor workers is 50 millisieverts, and Japan has increased it to 250. If I, and Bloomberg, are correct, I assume that a worker can only be near the reactor 2 water for an hour and then not be able to work there again. They are going to run out of workers pretty fast, if they need to be close to the water.

On a lighter note, I was talking to a Japanese friend this morning whose parents live at Chiba in Tokyo.  They have told him that bottled water is sold out, as is toilet paper. 

We both do not know why there would be a run on toilet paper.

The talented Mr Martin

Steve Martin and the Steep Canyon Rangers were on Colbert Report this week doing this song, but the sound quality was not as good as on this clip:

Uh-oh

I'm going to get accused of being into anti-nuclear disaster porn if I keep posting about this, but this is not good news that has just shown up on the New York Times:
Japan’s effort to contain the crisis at the Fukushima Daiichi nuclear plant suffered a setback, an official said on Friday, citing evidence that the reactor vessel of the No. 3 unit may have been damaged.

The development, described at a news conference by Hidehiko Nishiyama, deputy director-general of the Japan Nuclear and Industrial Safety Agency, raises the possibility that radiation from the mox fuel in the reactor — a combination of uranium and plutonium — could be released.

One sign that a breach may have occurred in the reactor vessel, Mr. Nishiyama said, took place on Thursday when three workers who were trying to connect an electrical cable to a pump in a turbine building next to the reactor were injured when they stepped into water that was found to be significantly more radioactive than normal in a reactor. The No. 3 unit, the only one of the six reactors at the site that uses the mox fuel, was damaged by a hydrogen explosion on March 14. Workers have been seeking to keep it cool by spraying it with seawater along with a more recent effort to restart the reactor’s cooling system.

In another development on Friday, the Japanese government said it would help people who wish to leave the area around the crippled plant, a sign that efforts to reassure frightened residents have failed to persuade people to stay.

Can't see it happening

Step 1 in asteroid mission: Pick right space rock

Given the currently unsolved problem of radiation in space, and the complete lack of any planning for a spacecraft big enough to accommodate a crew for the (what, one to two year?) return trip without them going stir crazy, I just can't see that a trip to an asteroid makes a sensible next step in space. At least if you go to the moon or Mars, you can get to stretch your legs in gravity at the half way point.

You have to lift your hands to touch the screen, though. Can't they do something about that?

The vege burger

The New York Times reports that some chefs are coming up with vegetarian burgers that really are good.

I don't mind trying vegetarian products from the supermarket every now and then. It's sort of interesting to see how good they can make their fake meat products. My wife has started doing a curry with fake chicken from Malaysia or somewhere: it's not bad, and I had the fun the other night of telling my son he had been fooled into thinking it was meat.

I think I have even mentioned in this blog before that, when I was single, I used to sometimes make chilli con carne using chunk style textured vegetable protein. But the after effects were such that married life meant I had to give that up.

This story will horrify at least one reader, hey Jason.

Help me Obi Wan, they took my carrot

Of course, you would have needed more than one R2D2 projecting the image, but it's looking close:

Back to the Future correct

JF Beck links to a bunch of old black and white photos of the (American) frontier life taken around 1890.

Viewing them reminds me that, when watching Back to the Future Part 3, I had thought that the 1885 version of Hill Valley looked a little too old time Western. But this is obviously not the case, when you see photos of the real era.

Fukushima notes

With the news last night that a couple of workers from the reactor are in hospital with radiation burns, it’s clear that the current operations remain very dangerous.   Even modest advances are being greeted as big progress:  for example, yesterday’s news that lights have been turned on in a couple of control rooms. 

Time magazine has an interesting entry about the ongoing issues at the plant.  As the New York Times noted, one concern is the use of seawater as a temporary coolant:

As  seawater evaporates, salt scaling could insulate the reactor fuel and impede heat transfer and thus cooling. In a worst case, as the rods heat up, their zirconium cladding could rupture, and  gaseous radioactive iodine inside could leak out; the uranium core itself could even melt. This, of course, would release event more radioactive material.

The BBC has a sort of retrospective of the last couple of weeks which is well worth reading too.

Meanwhile, I have stumbled across another example (apart from Andrew Bolt) of a climate change skeptic who has been in an unseemly rush to declare that there has barely been a major problem at all.

The Register, as I recall, has long been keen to run anti climate change articles.    If you have a look at the list of article titles by one Lewis Page,  who himself appears to be quite the CO2 skeptic, it makes for mildly comic reading:

14 March:   Fukushima is a triumph for nuke power: Build more reactors now!

First lines: 

Japan's nuclear powerplants have performed magnificently in the face of a disaster hugely greater than they were designed to withstand, remaining entirely safe throughout and sustaining only minor damage. The unfolding Fukushima story has enormously strengthened the case for advanced nations – including Japan – to build more nuclear powerplants, in the knowledge that no imaginable disaster can result in serious problems.

15 March: Fukushima update: No chance cooling fuel can breach vessels

16 March: Situation worsens - still no cause for alarm

17 March: Fukushima on Thursday: Prospects starting to look good

18 March: Fukushima one week on: Situation 'stable', says IAEA

21 March: Fukushima: Situation improving all the time. Food, water samples OK, Hyper Rescue Super Pump in action

22 March: Fukushima's toxic legacy: Ignorance and fear. Hysteria rages unchecked as minor incident winds down

23 March: Radioactive Tokyo tapwater HARMS BABIES ... if drunk for a year. Iodine isotope will all be gone in weeks, though

The glass is always more than half full for Mr Page.

A new political truism revealed

I have realised lately that, for some reason, male politicians who have too much curl in their hair just can't be taken very seriously. (I'm looking at you, John Paul Langbroek, Christopher Pyne, and Rand Paul.)

Sad for them, but true.

Need I say more?

[By the way, this and the last post represent the return of my use of the Blog This doo-dah from Google. I thought it didn't work on current versions of Firefox, but seemingly it does. It is, by far, the easiest way to open a blogging post window. Just click the button while you are looking at a page, and it opens a blog post window with the title of the article as a link at the top. I have found no other blogging add on that does the same, wonderfully simple, thing.

I thought it was a Firefox add on which had gone missing, but I see now that it is a Google tool for use with Blogger. It's very good, anyway.]

Really worth it?

Hand transplant man faces long recovery

It's one thing to have transplanted internal organ, where you're not necessarily reminded daily that part of someone else is now part of you. But it seems to me to be quite another to have a hand transplant. There's quite a lot to any transplant:

There is also a danger Mr Walsh's body could reject the new hand, with the first few months the most dangerous period.

He will require medication for the life of the transplant to slow his immune system and ensure it doesn't attack the transplant.

St Vincent's doctor, Robyn Langham, said that leaves his body less equipped to deal with rogue cells that might appear in the body.

"Those rogue cells do have the potential to turn into cancers," she said.

She said Mr Walsh may also be at greater risk of contracting metabolic conditions such as diabetes and osteoporosis.

Personally, even with no hands, I think I would be much more interested in having the latest and greatest robotic version than a transplant: I have a preference for Luke Skywalker over Dr Strangelove.

A product endorsement

I like it:

To be fair...

I have been meaning to say this in relation to the carbon tax/emissions trading scheme that's heading our way via Labor and the Greens.

While I find Garnaut a very credible figure, and consider in principle (as did the Coalition until Tony Abbott took over) that carbon pricing is an important step to reducing Australia's greenhouse gases, it still has to be said that the full structure of the scheme that the government settles on might prove to be very ineffective and not really worthy of support for a number of reasons.

The problem is, while the Coalition is on its "direct action is really a market scheme (and by the way, half of us believe there is no problem to be addressed at all)" wander in the wilderness, they are cutting themselves out of making credible contribution to getting the carbon pricing scheme right.

This is the tragedy of the current situation.
