A new strain of the gonorrhea bacteria can resist all available antibiotics, doctors say. Gonorrhea is one of the world’s most common sexually transmitted diseases, so this could portend a major threat to public health.
This should actually not be surprising, because for some time now, just one class of drug has been able to successfully treat the infection.
On a scale of 1 to George Michael, I'd put my gaydar at about 7. But evidently my so-so ability to spot a gay man sharpens close to when I'm ovulating, or if I've recently imagined myself in a romantic situation, according to a series of studies conducted at the University of Toronto. The results show that straight women are better at judging men's sexual orientation when they are unconsciously motivated to do so, either by hormonal fluctuations or by the power of suggestion.
When time travel finally becomes possible, we might want to think twice about getting it on. According to a new study on tiny shrimp (Artemia franciscana), sex with partners from a different time could kill you.
Back in 2002, psychologists at the State University of New York at Albany published a study in the Archives of Sexual Behavior looking at the potential role of semen in alleviating depression in women. The researchers presented evidence supporting an earlier hypothesis that the hormones in semen have a mood-boosting effect on women.
For the first time, scientists have discovered evidence of a human DNA fragment in the genome of bacteria, shedding light on why this particular bug is so adept at surviving in human hosts. The bacteria in question is Neisseria gonorrhoeae, which causes gonorrhea.
Here’s some futurey Valentine’s Day news: Future space colonists would likely be unable to procreate because of the ionizing radiation that permeates the solar system, according to a paper by NASA researchers.
Over the years, Popular Science has strived to answer your questions about the world we live in. What's on the moon? Why don't we have flying cars? How do magnets work? As compelling and relevant as these questions are, though, none inspires as much fury as the age-old debate on whether men and women are equally capable.
For the most part, we answered no. Like it or not, our magazine has always been a product of its time, and for at least the first 70 years of our 138-year history, we held men in higher esteem because science and feminist literature had not yet given us reason to believe that women could accomplish much on a grand scale.
The scent of a woman’s sadness — manifested in her tears — is a major turn-off for men, according to new research published today. It is the first study to suggest tears of emotion contain chemical signals that influence others’ behavior.
Using stem cell technology, scientists have produced male and female mice from two fathers, a breakthrough that could conceivably allow same-sex couples to have their own genetic children.
The multi-generational technique combines genes from the chromosomes of two male mice and uses surrogate mothers, according to researchers at the M.D. Anderson Cancer Center at the University of Texas.
