If you want to do a scientific study of sexual function (in this case, how orgasm changes genital sensitivity), it’s usually necessary to perform it under carefully controlled conditions. So how do you do that in the context of studying female orgasms? Check out the [probably NSFW] description below.
The effect of sexual arousal and orgasm on genital sensitivity has received little research attention, and no study has assessed sensation pleasurableness as well as painfulness.
To clarify the relationship between sexual arousal, orgasm, and sensitivity in a healthy female sample. Read More
What happens to a body buried in cement? How long does it take to decompose? In this study, the (Italian) scientists set out to answer these questions using (what else? ) piglet corpses. Don’t worry, the authors assure us that they died of “natural causes”…
Burial of piglet carcasses in cement: a study of macroscopic and microscopic alterations on an animal model.
“Scarce experimental data exist describing postmortem effects of burial in cement. The scanty literature presents several case reports, but no experimental study. To perform a pilot study, the following experimental system was designed: 4 piglet corpses, who died of natural causes, were encased in concrete. After 1, 2, 3, and 6 months, a block was opened, and autopsy and microscopic analyses were performed. Read More
Researcher: “C’mon elephant, the peanuts are right there. I’m pointing right at them!”
Elephant: *blank stare*
Researcher: “The dogs, goats, and horses can find them.”
Elephant: *blank stare*
Researcher: *sigh* “Fine. Just use your trunk then.”
“Recent research suggests that domesticated species – due to artificial selection by humans for specific, preferred behavioral traits – are better than wild animals at responding to visual cues given by humans about the location of hidden food. Although this seems to be supported by studies on a range of domesticated (including dogs, goats and horses) and wild (including wolves and chimpanzees) animals, there is also evidence that exposure to humans positively influences the ability of both wild and domesticated animals to follow these same cues. Here, we test the performance of Asian elephants (Elephas maximus) on an object choice task that provides them with visual-only cues given by humans about the location of hidden food. Read More
OK, we admit it, we just picked this one because of the title. But the method for removing objects from the rectum using a cluster of balloons is actually pretty inventive.
“Removal of a rectal foreign body (FB) has become increasingly common in the recent times. Nature of rectal FB is limited only by the imagination of the patient concerned. Many techniques have been described for removal and various theories have been put forward to explain the mechanics of the procedure. We report a case where a new technique had been employed.”
Bonus excerpt and figure from the main text:
“Techniques for the safe extraction of a rectal foreign body require ingenuity, but few authors have considered the mechanics of this surprisingly common procedure Read More
Do you have tasks that need doing but can’t afford to buy a robot? Look no further! Remote-controlled turtles can do your bidding, from… um … swimming in shallow waters? to … uh … walking really slowly on the land? Look, the point is that these scientists figured out how to make turtles do what they want simply by attaching a movable blinder to the turtle’s shell. This apparatus allows the scientists to control the turtles’ movements by activating their instinct to avoid obstacles (see it in action in the movie clip below). Turtle army!
Remote Guidance of Untrained Turtles by Controlling Voluntary Instinct Behavior
“Recently, several studies have been carried out on the direct control of behavior in insects and other lower animals in order to apply these behaviors to the performance of specialized tasks in an attempt to find more efficient means of carrying out these tasks than artificial intelligence agents. While most of the current methods cause involuntary behavior in animals by electronically stimulating the corresponding brain area or muscle, we show that, in turtles, it is also possible to control certain types of behavior, such as movement trajectory, by evoking an appropriate voluntary instinctive behavior.

This isn’t the first time we’ve highlighted a report of a bat species that engages in oral sex. However, this time it’s the females that get the extra attention. First fellatio, and now cunnilingus: who knew bat sex would be so hot? Be sure to the check out the perhaps-NSFW video from the paper’s supplementary information:
Cunnilingus Apparently Increases Duration of Copulation in the Indian Flying Fox, Pteropus giganteus.
“We observed a total of 57 incidences of copulation in a colony of the Indian flying fox, Pteropus giganteus, over 13 months under natural conditions. The colony consisted of about 420 individuals, roosting in a Ficus religiosa tree. Copulations occurred between 07.00 h and 09.30 h from July to January, with more occurring in October and November. Initially males groomed their penis before approaching a nearby female. Females typically moved away and males followed. When the female stopped moving, the male started licking her vagina (cunnilingus). Read More
You love to hate them: people in power who talk the talk but don’t walk the walk. I’m sure most of us have suffered a boss who tells you to do things that he or she doesn’t. But do these people become hypocrites because they are in positions of power, or were they just born a**holes? These scientists decided to find out! Turns out that power doesn’t just corrupt, it makes you a bigger hypocrite. Good thing I didn’t get that promotion after all.
Power increases hypocrisy: moralizing in reasoning, immorality in behavior.
“In five studies, we explored whether power increases moral hypocrisy (i.e., imposing strict moral standards on other people but practicing less strict moral behavior oneself). In Experiment 1, compared with the powerless, the powerful condemned other people’s cheating more, but also cheated more themselves. In Experiments 2 through 4, the powerful were more strict in judging other people’s moral transgressions than in judging their own transgressions. Read More
Your head throbs. You feel like you’ve been run over by a truck. Ugh. It’s no fun to go to work with a hangover. You want to call in and take one of your personal days, but is it really worth it? Are you actually going to be bad at your job, or should you just suck it up and go to work? Well, these scientists got 13 volunteers to go home, get wasted, and come back the next day to see if they performed as terribly as they felt. The results weren’t pretty.
The effects of self-administered alcohol-induced ‘hangover’ in a naturalistic setting on psychomotor and cognitive performance and subjective state.
“AIMS: To examine in as naturalistic a setting as possible whether having an alcohol-induced ‘hangover’ impairs psychomotor and cognitive performance. PARTICIPANTS AND DESIGN: The sample consisted of 71 male and female social drinkers who were tested twice, once at baseline and once after exposure to the study condition. They were randomized into a control group who returned for testing on a prearranged date (n = 33), and a group who were instructed to make arrangements to return the day after a self-determined heavy drinking session (n = 38).

It seems like everyone wants to figure out how to eat less. Some studies indicate that chewing more might help. But if you don’t have extra time to spend on mastication, you might want to read this study. Apparently, at least when eating a multi-course banquet of meatballs (M), french fries (F), brownies (B), and vanilla cream (C), the order in which you eat your chosen delicacies may influence the total amount you consume. So if you want to eat less dessert, try meatballs, then french fries, then meatballs, then french fries, then meatballs, then french fries, then vanilla cream, then brownies, then vanilla cream, then brownies, then vanilla cream. BEST DIET EVVAAARRRR! (Caveat: this will make you eat more french fries).
Alternation between foods within a meal. Influence on satiation and consumption in humans.
“Food habituation/dishabituation has been observed in non-human primates in neurophysiological investigations of feeding, and in humans, through salivation or hedonic responses to food. The objective of the study was to evaluate in humans the effect of disruption of habituation by alternation between foods in a meal. Sixteen volunteers (8 males, 8 females; age: 21+/-1 yr; BMI: 21.5+/-0.5 kgm(-2)) ate a two-course meal [meatballs (M) and fries (F), then vanilla cream (C) and brownies (B)] during three randomized sessions. Sessions differed by the alternation of these foods: No-Repetition session with M-F-C-B; Single-Repetition session with F-M-F-B-C-B; Multiple-Repetition session with M-F-M-F-M-F-C-B-C-B-C-B. Read More
