NCBI ROFL: Science brings hope for your ugly baby.

By ncbi rofl | January 23, 2012 6:51 pm

You must have been a beautiful baby: ratings of infant facial attractiveness fail to predict ratings of adult attractiveness.

“Facial attractiveness has been studied extensively, but little research has examined the stability of facial attractiveness of individuals across different stages of development. We conducted a study examining the relationship between facial attractiveness in infants (age 24 months and under) and the same individuals as young adults (age 16-18 years)using infant and adult photographs from high school yearbooks.

NCBI ROFL: The best men are (not always) already taken: female preference for single versus attached males depends on conception risk.

By ncbi rofl | January 20, 2012 7:22 pm

“Because men of higher genetic quality tend to be poorer partners and parents than men of lower genetic quality, women may profit from securing a stable investment from the latter, while obtaining good genes via extrapair mating with the former. Only if conception occurs, however, do the evolutionary benefits of such a strategy overcome its costs. Accordingly, we predicted that (a) partnered women should prefer attached men, because such men are more likely than single men to have pair-bonding qualities, and hence to be good replacement partners, and (b) this inclination should reverse when fertility rises, because attached men are less available for impromptu sex than single men.

NCBI ROFL: Apparently, jumping with a weighted vest or springs attached to your shoes is hard.

Effects of loading on maximum vertical jumps: Selective effects of weight and inertia.

“A novel loading method was applied to explore selective effects of externally added weight (W), weight and inertia (W+I), and inertia (I) on maximum counter-movement jumps (CMJ) performed with arm swing. Externally applied extended rubber bands and/or loaded vest added W, W+I, and I corresponding to 10-40% of subjects’ body mass. As expected, an increase in magnitude of all types of load was associated with an increase in ground reaction forces (GRF), as well as with a decrease in both the jumping performance and power output.

Effects of heated seats in vehicles on thermal comfort during the initial warm-up period.

“Eight subjects participated in a subjective experiment of eight conditions to investigate the effects of heated seats in vehicles on skin temperature, thermal sensation and thermal comfort during the initial warm-up period. The experimental conditions were designed as a combination of air temperature in the test room (5, 10, 15, or 20 °C) and heated seat (on/off). Read More


Go Ahead and Gossip—Science Says It's the Right Thing to Do

He did what? Innnnteresting…

Thorough scientific study has revealed that lots of supposed vices can have surprising upsides: alcoholsexcaffeine. Thanks to UC Berkeley researchers, we can now add another so-bad-but-oh-so-good habit to the list: Gossip, their new study suggests, can be a selfless act of public service.

Surreptitiously passing along the news that someone has behaved badly—what’s technically called “prosocial gossip”—can relieve stress, as well as warn others to regard the rule-breaker with a wary eye, the researchers say. (The study didn’t look directly at other forms of gossip—rumormongering, telling lies, anything said to a confessional cam on reality TV—so make of that what you will.)

NCBI ROFL: [Ring ring] … Hello? … Hi! Are you a lesbian?

By ncbi rofl | January 17, 2012 6:34 pm

A brief telephone interview to identify lesbian and bisexual women in random digit dialing sampling.

“Lesbian health research has most often relied on nonprobability samples that are biased and restrict generalizability. Random sampling could reduce bias, but requires development of a method for fast and reliable screening of a large number of women. We tested the feasibility of using a brief telephone interview to assess sexual attraction, behavior, and identity. Read More

NCBI ROFL: How to improve your human random number generator.

By ncbi rofl | January 16, 2012 7:01 pm

Doing better by getting worse: posthypnotic amnesia improves random number generation.

“Although forgetting is often regarded as a deficit that we need to control to optimize cognitive functioning, it can have beneficial effects in a number of contexts. We examined whether disrupting memory for previous numerical responses would attenuate repetition avoidance (the tendency to avoid repeating the same number) during random number generation and thereby improve the randomness of responses.

NCBI ROFL: Sexual attitudes as correlates of sexual details in human figure drawing.

By ncbi rofl | January 13, 2012 6:48 pm

“The hypothesis that sexual attitudes, as measured by the Sexual Opinion Survey, are related to the explicitness with which nude figures are drawn was examined. The presence or absence of various sexual and nonsexual anatomical features, as well as length and width measurements, were assessed in the drawing of nudes by 17 male and 23 female undergraduates.

Intestinal hydrogen and methane of men fed space diet.

“Intestinal bacteria form two gases, hydrogen (H2) and methane (CH4), that could constitute a fire hazard in a closed chamber. So H2 and CH4 pass from the anus but these gases are also transported by the blood to the lungs and removed to the atmosphere. Several factors affect gas formation: 1) amount and kind of fermentable substrate; 2) abundance, types, and location of microflora; and 3) psychic and somatic conditions that affect the gut.

High Schoolers Fold TP a Record Number of Times, Can Now Pad Resumes

By Valerie Ross | January 12, 2012 2:48 pm

High school kids armed with rolls of toilet paper usually mean there’s going to be a mess on someone’s lawn. A group of Massachusetts students, who had amassed a stockpile of more than 10 miles of toilet paper, could have been the terror of the neighborhood—had they not put their arsenal towards a more cerebral purpose: folding it 13 times. Folding toilet paper hardly sounds like an accomplishment, particularly to those of us who are long since potty trained, but try folding a spare sheet (of any paper) and see how many folds you can manage; until recently, folding paper more than seven times was thought to be mathematically impossible.

But these high schoolers (and their enthusiastic math teacher) crunched the numbers and got to folding, nearly doubling the long-assumed limit and surpassing the 2002 record of 12 folds. The resulting structure stood two-and-a-half feet tall and was made of 8192 layers of toilet tissue. Just in case 2-ply wasn’t enough.
