Strong Education Blunts Effects of Alzheimer's Disease, Study Suggests

piggy submitted, created time 1 week 3 days (www.sciencedaily.com)

A test that reveals brain changes believed to be at the heart of Alzheimer's disease has bolstered the theory that education can delay the onset of the dementia and cognitive decline that are characteristic of the disorder.

Scientists at the Alzheimer's Disease Research Center at Washington University School of Medicine in St. Louis found that some study participants who appeared to have the brain plaques long associated with Alzheimer's disease still received high scores on tests of their cognitive ability

Bradley Effect abstains from 2008 election

Darkfrog submitted, created time 2 weeks 1 day (www.nytimes.com)

This year's election day showed record turnout among voters, but there was one factor that didn't show up at the polls: The Bradley Effect.

The Bradley Effect is a phenomenon that occurs when a black or other minority candidate runs for political office. The idea is that more people will be willing to vote against a minority candidate in the privacy of the voting booth than will be willing to admit it to pollsters face-to-face. It is named after a Tom Bradley, a black Californian who lost the 1982 race for governor despite polls predicting that he would win

Gene-testing startup's study responds to critics

jerry submitted, created time 1 month 1 week (ap.google.com)

Navigenics, a Silicon Valley gene-testing startup is sick of all the criticism. The service that Navigenics offers is called personal genetic testing. Their customers are given a genetic writeup that covers markers for diseases like multiple schlerosis, glaucoma, obesity, and some kinds of cancers. Neither the article nor the Navigenics website says whether these customers are people who already have a family history of these conditions and wish to learn whether they inherited the tendency or whether they are simply curious

What better place to discuss computer science, really? For practicality reasons, it was a Horde-only conference. Any newb or Alliance player was required to create a new character and level up ahead of time so that older players wouldn't have to spend the whole time fending off monsters with the munchies

A Black-White Diabetes Divide

jerry submitted, created time 5 months 1 week (www.time.com)

A study finds that white patients on average fare better than black patients treated by the same doctors. No previous study has managed to adjust for the patient's economic situation in this way. Age, gender, obesity levels, everything was taken into account. The white patients fared better across the board.

One hypothesis seems most likely to be correct: It isn't that the doctors aren't treating the patients the same, but that they are. The patients from each subculture, says Thomas Sequist, face different challenges in sticking to their food and exercise regimens.

Happily married adults have lower blood pressure than singles with supportive social networks. Both men and women in happy marriages scored four points lower on 24-hour blood pressure than single adults. Having supportive friends did not translate into improved blood pressure for singles or unhappily marrieds.

Flash-freezing changes the face of fertility, but not by much

Darkfrog submitted, created time 10 months 3 weeks (www.nytimes.com)

This article is as much about politics and attitude as it is about the new flash-freezing method, called vitrification, that allows women to preserve their genetic material without settling on a sperm donor or real-life partner first. The scientists in this article claim that the flash-freezing of unfertilized human ova, a relatively new process that improves the survival rate over conventional freezing, will "emancipate women as much as the birth control pill did in 1960

So Cute You Could Just Eat Them Up

Eric wu submitted, created time 1 year 5 days (sciencenow.sciencemag.org)

Most likely, your mother nurtured you for years and you never worried that when you came home from kindergarten, she'd gobble you up. But many animals do occasionally eat their young, including many that also are attentive parents. New research indicates that, when it comes to deciding whether to chow down on junior, Ma and Pa may be motivated by more than hunger. For example, parents may selectively eat their weaker offspring to favor the stronger ones, an evolutionary model predicts.

Studies on number of sexual partners serve as model for analysis of fallacies in studies

Darkfrog submitted, created time 1 year 3 months (www.nytimes.com)

This article is a good example of an examination of the flaws of a set of sociological studies, of the attempt to reconcile the data with logic (ever the scientist's quest) and of how stereotypes can reinforce themselves.

Many sociology and human behavior studies show that, over the course of their lifetimes, men have more female sexual partners than women have male sexual partners -- or at least that the study respondents claim so.

This NYT article claims that this must be a fallacy

Paternity discrepancy -- society, trust and possible evolutionary basis

Darkfrog submitted, created time 1 year 6 months (men.msn.com)

This is a little less reputable than I usually prefer to post. It is mostly about social roles and trust issues, but it does address the evolutionary aspects of fatherhood. Mostly, I've just never heard of "paternity discrepancy" before. It refers to the phenomenon of a man raising a child that is not, despite his beliefs to the contrary, his genetic offspring. (Knowing adoptive fathers and stepfathers do not apply.)

The article quotes Dr

Teens report both positive and negative emotional effects of sexual contact

Darkfrog submitted, created time 1 year 9 months (www.sciam.com)

This study out of the University of California seems to show that about one-third of American teenagers who have sexual experiences, even if it's not sexual intercourse in the Clintonian sense, report negative feelings, like feeling guilty or used. The study shows that girls are twice as likely as boys to feel bad and strongly recommends that parents talk to their children about the emotional consequences of unwise sexual decisions. However, it also shows that teenagers can feel strong good emotions and that these are more common.
