In Curious Behavior: Yawning, Laughing, Hiccupping, and Beyond, which published last week, Robert R. Provine, a professor of psychology and neuroscience at the University of Maryland, Baltimore County sets out to answer some of biology's burning questions: Why are yawns contagious? Why do we cry tears? Why does light make (some of) us sneeze? And my personal favorite: Why don't we talk out of our butts?
As you've probably heard by now, in an interview Sunday, Missouri Representative and Republican Senate nominee Todd Akin said he believed that rape-related pregnancy was "really rare." He continued by saying that, "If it's a legitimate rape, the female body has ways to try to shut that whole thing down."
So, now for the facts. Pregnancy resulting from rape is not rare. In fact, a woman is more than twice as likely to get pregnant during a rape than during consensual sex.
Recent research tells us that the sound of our voices betrays clues about our age, whether we're menstruating (if we're female), our sexual behavior and our physical strength. All of these factors, evolutionary psychologists say, are indicators of her reproductive potential.
Cornell University researchers used porn and measures of pupil dilation to study arousal in straight-, gay- and bisexual-identifying men and women, reports a study published April 3 in PLoS ONE. The results, which point to surprising differences in arousal based on a person's sex and sexual orientation, corroborate previous research using measures of genital response, opening up a less-invasive method of studying arousal and orientation.
For decades, researchers have argued over the existence of the G-spot, a supersensitive spongy organ on the front vaginal wall that many women report causes vaginal, rather than clitoral, orgasms. Now, a cosmetic surgeon in Florida says he's finally found the G-spot in a dissected cadaver, but rather than settling the question of the G-spot once and for all, the new findings are kicking off a new round of debate.
According to a new study by sex researchers at the Indiana University, women having orgasms during exercise is a real phenomenon. As far as the researchers know, this is the first study that deals directly with exercise-induced orgasms (EIO), known colloquially as "coregasms" because they tend to occur during core-strengthening workouts, like sit-ups and crunches.
On August 5, NASA’s Mars Science Laboratory will reach the outer edge of the Martian atmosphere. The 8,500-pound craft will have traveled 352 million miles at speeds of up to 13,200 mph, but its real work will have only just begun. Over the next seven minutes it will plummet through 80 miles of atmosphere, withstanding temperatures of up to 3,800°F, and guide itself to a sudden halt in the massive Gale Crater.
