Parasites Makes Us Dumber or Sexier
odie_q writes "It has long been known that the Toxoplasma gondii parasite alters its host's behavior, but now it seems the way it alters it depends on the sex of the host. From the article: 'A common parasite can increase a women's attractiveness to the opposite sex but also make men more stupid, an Australian researcher says ... Infected men have lower IQs, achieve a lower level of education and have shorter attention spans. They are also more likely to break rules and take risks, be more independent, more anti-social, suspicious, jealous and morose, and are deemed less attractive to women. On the other hand, infected women tend to be more outgoing, friendly, more promiscuous, and are considered more attractive to men compared with non-infected controls.'"
Clearly, this is a textbook case of toxoplasmosis. You should keep your hands out of the litter box.

What are the odds that guys with low IQs, short attention spans, and an affinity for risks are just more likely to eat undercooked meat, and that the more outgoing promiscuous women catch it because of them.

I found this piece of news very interesting. Is it known how the parasite affects our behavior? If it secretes a chemical that has the effect, I'd say this could be used for treatment in a variety of medical conditions. If it "attacks" specific areas of the brain, it may reveal interesting things about it.
Things such as this hints to how our minds work, which is possibly one of the most fascinating things in the universe (:

For those who didn't RTFA, one of the ways of catching this disease is by accidentally digesting cat feces (if the cat is effected with the bacteria). Smokey is a fairly common name for a grey cat here in the States.

------ The best brain training is now totally free : )
I believe this is one of those news stories that sits around waiting for a slow news day. The original paper was released in November. It's written by Kevin Lafferty and was published in Proc. Roy. Soc. B.
It's a really quite fascinating paper - I recommend tracking it down if you can get access. Here's how it goes: Toxoplasmia gondii is adapated to live in cats and reproduces in felid intestinal cells & is shed, encysted, in their feaces. Then it can directly infect cats who come into contact with the cysts, or it encysts in brains of smaller mammals, and moves up the food chain as they get eaten until it hits a cat, and can reproduce again.
Fascinatingly, T.g. appears to affect rodent behavior to increase predation risk - i.e. the rodents become more active, less fearful of cat/cat smells, and have increased dopamine levels (which supposedly leads to novelty seeking behavior and neuroticism-type behaviors, or at least, they do in humans).
Despite humans not having any major cat predators, it could still affect us as a byproduct type of thing. Particularly that whole dopamine increase - this is should increase neuroticism levels.
So - the big question - does prevalence of T.g. correlate with cultural variation in neuroticism in humans? Lafferty finds a fairly strong correlation ( r2 of 0.38 ) between population aggregate neuroticism (as measured by the fairly standard NEO PI-R personality inventory ).
Unfortunately I think the populations he uses for his stats are a little bit suspect (always the problem with worldwide analyses though), but it's definitely worth a read. You should also keep in mind that so far it's only an interesting correlation and not a direct demonstration that T.g. causes large scale cultural differences.

Alright, fantastic. A parasite that might be able to change my behaviour. Possibly for the worse. Naturally, I don't particularly relish the idea that there's a parasite in my brain effecting the way I think and act.
So, assuming one has such a parasite, are there treatments to get rid of it?
I am pretty sure this is a dupe and was already discussed to death. I am trying to fight the slashdot search engine but up to now "parasite" and "toxoplasm" did not give any search result back... Maybe someone can point out what article it was ?

What do you mean by more stupid?

I keep telling you people there has to be something in the water making humanity stooooopid.
"Never attribute to malice what can be explained by incompetence".
I so hoped that George W. Bush would win the 2004 elections to make sure he is still president when the failure of his presidency becomes more clear. So no one can blame the ongoing breakdown in Iraq and the reappearing Taliban in Afghanistan to a liberal and weak Democrat administration which messes anything up the Bush Administration has started.
I was starting to wonder if the strategies of the Bush administration might just be based on complete incompetence and ignorance after them closing in on Iraq in connection to 9/11. I had a teacher who was in Iraq on a development project in the 1970ies with still some connections there, and according to her Iraq had a mainly agnostic government based on arabic-nationalist and socialist ideas (e.g. arabic nationalsocialism). Tariq Aziz, the former second man in Iraq, is a maronite christian, not a muslim after all. So all alleged connections to a fundamentalist muslim group were doubtfull at best. Saddam Hussein was trying to play the muslim card after the fall of the Berlin Wall and the demise of the Soviet Union, because Socialism was no longer fashionable, but with the Gulf War in 1992 the Muslim Card also failed because all neighboring states (both baathist/fascist like Syria and fundamentally islamic as Saudi Arabia and the Gulf Sheikdoms) were telling him off.
In the end Saddam Hussein seemed to me just a dictator which tried to cling on power with all means, and I guess he was completely unideologic except for the ideology that he was not to be toppled.
A big hint to the complete misinterpretation of the situation in Iraq was to me that the development of the war was so different from the predictions. The South, which was considered pro-intervention and expected to greet the U.S. troups with flowers and celebration, was fighting hard, and the Sunni Triangle, which was suspected to be strongly defended and determined for a last stand, was taken within the matter of days. When the toppling of Saddam's statue in Bagdad was mainly watched with lethargy by the people (compare the video footage with that of the Berlin Wall in 1989!) and only a U.S. tank managed to pull it down finally I knew: The invasion was utterly botched, and the Iraqi population was at best waiting how it would work out in the end. The plundering and looting in the following weeks might have finally tilted the balance against the U.S., and at this very moment I was sure that the cause of "bringing democracy to the Arab world" was lost.
It just took two hundred thousands dead Iraqis, the Abu Guraib scandal, the Guantanamo disaster and another three years of ongoing insurgence in Iraq to let the U.S. electorate figure out the same thing. And the Bush administration seems only to have changed course to avoid a complete election catastrophe in November 2006. So this movement seems not to be not based in a thinking process within the administation, but just a tactic maneuver to stay in power.

Or is the behavior being interpreted differently based on gender?
It sounds like the parasite simply amplifies the affects of certain sex hormones in both sexes, and lowers inhibitions... In civilized men, too much of a good thing. (For less civilized men, it means "Jackass: The movie".) As for women, it's hard to draw conclusions about the intelligence of someone who's "more outgoing, friendly, more promiscuous". Some would consider that to be potentially more "risky," regardless of the fact that most men like the end result.
Since the rat study indicated that the parasite changed rat behavior to increase its own chances of survival (while putting the host rat at risk of being eaten by a cat), I wonder if the results of the behavior modification in humans could potentially result in more pregnancies and might therefore be a failed attempt by the parasite to insure survival as well.
If the parasite works by increasing dopamine levels in the brain, that would most certainly not decrease attention span or reaction time, it would in fact improve them, as can be seen when you take any dopaminergic drug. Higher dopamine doesn't hinder academic achievement, nor will it lower your IQ. That is ridiculous-- most of the mental benefits from cardiovascular exercise come from increased DA levels. Further, the effects of dopamine are not so sexually dimorphic in humans, the only real difference is that estrogen increases DA sensitivity. The archetypal drugs for increasing DA levels? Ritalin and Adderall.
These are low quality studies and an abomination of science to conclude that correlation = causation. Nothing is further from the truth! The main way toxoplasma is spread in humans is in eating undercooked meat. Considering the actual effects of dopamine on the brain, doesn't it seem more likely that perhaps a low IQ, low educational achievement, and risk taking/promiscuous behavior predispose one to eat or undercook meat? But even that is untested.
This study is wrong - all of us know that's not how it works!

This sig only exists because you are observing it.
This is bullshit. There is very little to no legitimate scientific evidence that this parasite effects the brains of humans at all.
That might be true, or the effect is the same (increases factor X in brain) but men and women react different to it because men already have a higher level of factor X in their brain. Like a little alcohol may make you more talkative/uninhibited/nice, but a lot makes you stupid or keel over. :)

I remember reading a few months ago that some reseachers had a found a higher incidence of schizophrenia among persons who, when small children, had had cats in their households, leading some to believe that Toxoplasmosis gondii may be a causal factor. Apparently, it is claimed that new research has confirmed this. This is of personal interest to me because my 14 year-old son was infected by Toxoplasmosis a couple years ago during a vist to Trinidad. Physicians suspect that the most likely source was my wife's aunt's home-made yogurt, which my kids love. My wife's aunt is an animal lover, and keeps numerous dogs and cats, as well as feeding hosts of wild birds that descend on the house every morning.
It was discovered after he complained about spots in his vision, and an opthalmological determined that there was a lesion on his retina which was flaking away. A blood test confirmed the presence of Toxoplasmosis gondii. Now he has to have an annual examination to ensure that the parasite is being kept under control by antibiotics, but it's always an extremely apprehensive time for us.

Maybe these researchers have seen too many Star Wars movies where the "midichlorians" (or however that's spelled) control everything through "The Force". When that concept first came out in Star Wars, I thought Lucas had totally lost it - it was brain dead.
OTOH, I've thought about Drexler's notion of embedding nanotech computers and robots into every cell of the human body. What would happen if you had trillions of human cells loaded up with distributed nanotech - or even femtotech or picotech - hardware that could monitor and totally control the human body and brain in realtime?
That would pretty much solve the God question.

It depends on why you think they invaded Iraq in the first place. Lets start with the original ones:
-Stop imminent danger to America from Weapons of mass distruction
-Bring peace and democracy to Iraq
-Get people who were involved with 9/11
Ok, so they're no good anymore, so what are they currently saying?
-Bring to justice a corrupt dictator
-Rebuild Iraq, hand over running to Iraquis and exit with dignity.
Ok, so apparently the first one is done, and the other looks a long way off. There's no basic services, and peace and self-sufficiency seem decades away. But there are some things that have been achieved. To the US taxpayer, or family member of those serving, it may not look like a victory. But for some people, the war is a massive success:
-Stopped Iraq from selling oil in Euros, rather than US$
-Demonstrate acceptance of American people for a pre-emptive, internationally condemmed war.
-Occupied countries and military bases on the western (Iraq) and Eastern (Afghanistan) borders of Iran
-Increased military spending
-Real life operations practice for US forces and test ground for new weapons technology
-Re-building and resource extraction contracts handed out to US firms.
The article mentions that there are drugs that can kill the parasite in rodents, and that it reverses the affects. There is no mention of the existence or lack of existence of a cure for humans. So... is it treatable?

If you replace "brought to justice" with "was executed very fast after only a single aspect of his dictatorship was slightly touched", then I agree.
Yet commandeering someone to kill 148 people was surely already forbidden in the old iraqi law. Why not take the old laws and sentence Saddam Hussein according to them? Why artificially create new laws and enact them retroactively? If you want to prove that someone is bad and does illegal things, then start with looking at the laws in place when the suspected crime was done. He was a dictator after all, I am pretty sure that he didn't care if his actions were backed by a fresh law overriding the old ones.
Getting the Shiites to cheer for Saddam Husseins execution was easy. They would also have cheered for him being executed for stealing candy. Getting the Sunnites to agree that he was a criminal is the hard part, and the way the process was done this chance was completely flundered. In the end Saddam Hussein was executed, but not brought to justice.
I don't think it's "justice" if you create new laws afterwards and then tell people that they have run afoul of them. I know that this is very en vogue after 9/11, and suddenly "helping or being trained as a terrorist" is a criminal act, and it's up to the government to define case by case, what that means.
What was until 2001 some kind of strange adventure vacation with some preaching, some training in a shooting range and lots of comraderie, completely has changed, and now you get indefinitely hold in detention without access to a lawyer, even though you might have been there decades ago and maybe even left soon after arrival because the camp looked too suspicious to you.
What was an act of charity to some social organisations in the land of your roots, where you still have family ties now is "financing international terrorism" and also gets you in jail, even though you only wanted to help the creation of an elementary school in the village of your ancestors. And again it may be that it also puts you in jail retroactively for money you spend years ago.
There's no basic services, and peace and self-sufficiency seem decades away. But there are some things that have been achieved. To the US taxpayer, or family member of those serving, it may not look like a victory. But for some people, the war is a massive success:
-Stopped Iraq from selling oil in Euros, rather than US$

-Increased military spending

-Re-building and resource extraction contracts handed out to US firms.
As far as I see stopping Iraq selling oil for Euros (which Iraq only announced and never did) didn't help the U.S. dollar if you just look at the exchange ratios. From the heydays of 2002, when the Euro traded for about 0.90 US$ we have a steep decline to today's ~1.30 US$. The whole US economy was devalued 30% during the last five years. To offset that you would need a yearly gross economy growth of about 6%, but the US economy achieved a maximum of about 4%. Calculated in Euros the US economy shrunk 2% a year.
Basicly what you are saying is that spending half a trillion of US$ a year to a very small part of the U.S. economy and the U.S. people is somehow a success. If you happen to be involved with either the companies or the people, I could agree. But wouldn't it be much more effective and cheaper if the money doesn't need to be laundered by a war but be sent directly? Ju
The execution is over the small, early stuff because it doesn't involve any western governments like his later crimes did.
Uncle Sam says:
Apart from:
-Invading the country
-Deploying hundreds of thousands of troops
-Installing a government
-Picking the court
Apart from that - We weren't involved! The Iraquis were responsible for all of this trial!
But wouldn't it be much more effective and cheaper if the money doesn't need to be laundered by a war but be sent directly? Just sent US$ 1500 each year to each citizen of the U.S.
This was mentioned in 1984, building and destroying military objects and digging and filling in holes have the same net outcome (ie make-work, no value) but one is so much easier to sell the population on.
It's how you sell the idea:
Will you vote to give money to rich corporations on a stupid war? -> No
Do you think we should pay American business top dollar to provide the best for our fighting troops? -> Yup.
Yes I agree the American economy, I am very very bearish on the economy overall. However, most people feel good about it, happy that their houses are worth lots of money, and their stocks are worth lots of money, everything is at a record high. But what if the way you keep score on things keeps losing its value? You feel rich... you vote incumbent... the fiscal liquidity tap keeps running...
The US could probably do a lot of damage to Iran by bombing it with aircraft and just trying to destroy things, but not do any kind of holding of ground whatsoever. They have infinite money (as much as they can print and hope the rest fo the world believes in) and could just sit back and use high-tech to destroy things. They suck at holding things, and winning the trust of the locals.
While the whole debacle is obviously bad for the economy overall, it does make some people a lot of money. Sure the deficits up, but their government contract is increased. The dollar is down 30% relative to other currencies but I've quadrupled my money so even in real terms, I'm still WAAAY up.
