When I was in graduate school, I wondered what changes made erectile tissue in the penis shift from its soft and flexible state to its stiff and inextensible state. Then, with the help of some armadillos, I did the research and figured it out. Tell me what you wonder about, and I’ll see whether I can figure it out for… »
People have always wondered about sex, and as literacy became more widespread over the course of the seventeenth century in England, books appeared to feed that curiosity.
For decades, gadget pundit Leo Laporte, the host of a variety of internet and TV talk shows, has served as the neighborly face of technology. And just like some actual neighbors, he has a history of accidentally exposing himself. This time, his audience was treated to a photo of a penis, spotted among a collection of… »
The Cell Picture Show has collected ten images of sexually significant science from labs around the world: the resulting slideshow (summarized in their image above) takes you on a walk through sex systems across many types of living things. »
You may have noticed some news around these weird sounding devices that measure “arousal”. They don’t. But they do measure changes in penile shape, and as such, can give users a rough estimate – in a non-invasive way – of how much blood is flowing into the penis during erection. »
When a company or website you trust gets hacked, it can be pretty unnerving. Particularly if you trusted that company with your credit card or medical information. But what if the hackers had knowledge of your sex life instead? That could be a reality: AdultFriendFinder has suffered a massive data breach. »
We’ve been breeding the fly Drosophila melanogaster in the lab for decades. We’ve tinkered with their genes — giving them extra legs, curly wings, or odd colored eyes – in pursuit of understanding genetic inheritance and how tissues develop. But until now we didn’t know which chemical made them start to mate. »
Wolf spiders are deaf—they don’t have the right structures for hearing. However, they are very good at sensing other kinds of vibrations, and they use this ability to communicate. One species of wolf spider plays songs on dead leaves to attract mates.
Crab lice (Pthirus pubis) aren’t crabs at all—they’re parasitic insects that feed exclusively on human blood, and their bites can cause intense itching in their hosts. Often, this itching happens in the pubic area, which is why they’re also known as “pubic lice”—which, it turns out, is actually a misnomer. »
Nearly 100 years ago, there was no drug to help with erectile dysfunction, but Bernard Scheinkman came up with an alternative. It’s not clear whether this nightmarish penile splint was ever manufactured — but you have to love the baroque logic of combining a cock ring, an open condom, and a shelf. »
Viagra. Levitra. Cialis. Stendra. For millions of men with erectile dysfunction, these drugs are the action heroes of the bedroom, breaking down the barriers that keep them from a normal sex life. Here’s how they work. »
Every spring, male red-sided garter snakes enter the mother of all meat-markets. While mature males can breed every year, females are only fertile once every three years, which puts them in very short supply. The result? Snake orgy, obviously. But for male snakes, this sexual free-for-all comes at a surprisingly high… »
