Angry Sex and Chocolate 

No, it's not (just) what I did last night. A Leeds PhD candidate has written reveals, in her forthcoming thesis, the blindingly obvious fact that people liked porn even before the modern era (anyone surprised by this should take a Japanese art history class). Her work focused on erotic literature published in the 1700's in England, and she found that public and group readings were not uncommon, and that even the poor (who were considered illiterate because they could not write, but could read) were at least as big fans as the gentry. She also found that much of the material was, er, not especially complimentary towards women.

What they didn't have in the 18th century, on the other hand, was oral contraception. Unfortunately, it seems that modern women may also stop having that too, thanks to a 2005 Medicare-budget-slash which stopped incentives for pharmaceutical companies to provide pill discounts to school health facilities.

Once all of our current college students have their babies, they will have to worry about caring for them. Science, unfortunately, is no help there: studies indicate that good-quality child care is both good and bad for kids. I wonder what the actual research publications say (as opposed to what The Weekly ReaderUSA Today says).

What goes with sex? Anger! And testosterone. A study has found that viewing angry faces stimulate learning and cognitive performance in people with high testosterone. This really has little to do with sex, but it was fun to try and make the association.

To have sex at all, you want to be in good health. What's good for you? Chocolate!!! Another study has found that eating dark chocolate improves circulatory health, and doesn't necessarily lead to weight gain. Also, blueberries might help prevent bowel cancer. And aren't chocolate-covered blueberries an aphrodisiac?

Permanent Damage 

We learned last week that stress seems to be especially bad for kids - this week suggests another reason why. Illinois researchers found that when young rats were severely stressed, new brain cells they generated die off more than expected. This could lead to any number of problems later on, but may point at some kind of interventions for people after severely traumatic experiences.

Speaking of traumatizing: it appears that snowboarders, aside from being annoying what with their constant extreme this and extreme that, are stressing out alpine wildlife, and putting them at risk. I wonder if snowboarders' frequently enviro-hippie nature will persuade them to take more care, or if this just makes them feel more EXTREME.

Brain damage is, of course, a really stressful event. A French case study suggests that some help may come to the severely brain-damaged from a surprising source: the drug zolpidem (Ambien). A woman who had had severe hypoxic brain damage, leaving her unable to move, speak, or care for herself at all, was able to move and feed herself, and communicate on some levels, when treated with the drug. Trials are underway, but the presumed mechanism is zolpidem's agonism of the GABA system. This is really cool.

Finally, some really good news (maybe) comers from Manchester. Researchers there have found a possible key to TB's toughness: it contains many more P450 genes than are expected from bacteria. The upshot of this is that a class of antifungal drugs, the azoles, can kill TB by inhibiting this molecule. This is potentially a MAJOR step in finally getting rid of TB, which kills millions of (mostly poor) people each year.

UPDATE: Men stare at people and animal's crotches when watching TV, women look at faces. Yeah, this pretty much sums up gender theory. (via BoingBoing)

Cyborgs and Fat Ladies 

A US study of women has found that those who eat more non-fat dairy products have more trouble conceiving than those who ate full-fat dairy. The results are a bit confusing - no one is sure why the effect is seen...it could be an effect of the processing involved in making nonfat products, or it could be something that's simply missing from the nonfat varieties that helps conception. The latter seems really unlikely, as I'm pretty sure that vegan women are generally able to have kids without trouble. Also, the study doesn't appear to have controlled for obesity - another risk for infertility, which could also motivate women to switch to nonfat foods.

Still, any excuse for ice cream will do.

Not really related, we have Chinese scientists' announcement that they have produced cyborg pigeons. Chips implanted in the flying rats' brains allows humans to 'remote control' their movements, possibly presaging a real reason to off that old lady next door who feeds the damn things: she's helping the gub'men spy on us! Seriously though, as scary as armies of robo-spies may be, this advance not only represents, but could dramatically further, our understanding of how the brain works.

Hairy Women, Geezers, Herpes 

And lots of other stuff too: it's been a crazy couple of days! First of all, Turkish researchers have found that drinking spearmint tea reduces free testosterone levels - offering a potential avenue for future treatment of severe hairiness. Also enough to drop mens' libidos, it seems, so boys should probably steer clear.

Speaking of looking good, Columbia researchers have found that living in densely populated areas, with a mix of residential and commercial spaces and transit options, is related to significantly lower BMI. Philosophically I hate BMI studies, as BMI is a terrible measure for obesity (while technically it should include a body composition component, in practice it's just weight/height^2), but it is a useful blunt instrument for this kind of study. Hopefully these results will result in people getting on with better smart development, etc.

We humans like to think that we're pretty special. We probably are, but we also have a lot more to learn about how other animals work. For instance, UK researchers have found that at least one species of bird, the western scrub-jay, conscientiously plans for the future - something only humans were believed able to do. In a really elegant-sounding experiment, the researchers taught jays that they might be denied their usual breakfast, but gave them the opportunity to store food instead. The birds not only hid food in the right places, but also hid a variety of it as well. Like setting up a menu. Cool!

And then there's chimps. Our closest cousins, they do all kinds of stuff that we used to like to think was unique to us. Now, researchers have observed wild chimps doing something really 'human': making spears to hunt prey. Whether or not we're actually seeing cultural evolution in action, or if this is an old trick we've just never before observed (unlikely), this is a really amazing discovery, and has huge implications for all kinds of stuff.

While animals are looking cleverer and cleverer, old people just got less clever and more annoying. OK, well, not really, now there's just a study to say so. A UVa study of older (60-80 years) and younger adults (under 60) found that while there were no differences in actual memory recall between the two groups, the old folks were much more adamant about their wrong answers. This study has implications not only for criminal justice (eyewitness accounts are the focus of the paper), but also for generally confirming how stubborn Grandpa is. And taking the leap of generalizing this to 80-100+ year-olds, who probably do have real memory problems, is a scary vision of a really frustrating place*.

And finally, to get to such stubborn old age, you have to not die first. One good way to die first is, of course, to get AIDS**. But, an African study has made an interesting discovery: an drug used to treat genital herpes seems also to reduce circulating HIV load by as much as 70%. Use of these drugs in HIV patients (who are frequently co-infected with HSV) could greatly reduce transmission and help prevent tons of cases. Assuming HIV doesn't mutate and render them ineffective. Also, it'll be really interesting to see how, exactly, the effect happens at a molecular level.

* To all who say that this stubbornness is part of old people's charm, I say yes of course it is: as long as it's someone else's problem.
** That's right kids - even with all the new modern treatments, including the one I'm about to tell you about, AIDS will still make you sick and die younger. So please, kill this 'barebacking' meme that's going around the gay community. Now.

Bad News for Feminists, Good News for Audiophiles 

In a turn sure to depress, enrage, and otherwise irritate the womens' movement, it seems that women who do more housework may be less likely to get breast cancer. Truthfully, what the researchers found was that women who were not obese and got a good amount of moderately strenuous exercise were less likely to develop the disease, but it seems that the way women were getting said exercise was by doing housework. (insert your own vaguely demeaning and sexist comment about the dust in my apartment here...I'm too tired to think of one)

On the upside, an Austrian has performed a recently discovered 'lost' Mozart composition. If it really is by Mozart, that's pretty cool. Actually, if it's good, it's pretty cool!

Also sadly, but worth coming out to celebrate, is tonight's penultimate Bluestate at the Black Cat. It's free, there will be dancing, and there will be ridiculousness. See you there!
