On July 9th of this year, divers off the coast of Turkey ran across an enormous lump of gelatinous goo which turned out to be one of the largest squid egg masses ever found. That inspired science writer and squid expert Danna Staaf to make this video explaining how all that goo fit inside a much smaller mother squid. »
Not one, not two, but four pelvic floor exercise devices are hitting the market to encourage women to do their Kegels. Rose Eleveth talks to their creators about their mission to help strengthen hidden (but important) muscles and asks whether the process really needs to be gamified. Check out the article at Refinery… »
You already know that a penis has arteries to bring blood to its erectile tissues, and veins that take the blood away again when it returns to its normal flaccid state. You may not know that there’s another set of vessels tucked under its skin. We just got our first good look at them. »
Her Majesty Queen Elizabeth II is showing the world sketches of penises and vulvas. Admittedly, they’re penises and vulvas that Leonardo da Vinci drew around 1508, which makes them art instead of crotch shots. Check ‘em out at the oh-so-proper Royal Collection Trust website. »
A couple of months ago, I helped out in Patricia Brennan’s lab when she made casts of dolphin vaginas. You heard me correctly. Dolphin vaginas. »
It definitely takes two when it comes to making baby flies. Scientists have known for years that fly semen can trigger ovulation and make females lay more eggs. But no one knew exactly what those proteins did to the female reproductive tract. A new study published in PNAS takes a deep look inside fruit flies to find… »
Human vaginas don’t have the fantastical loops and blind alleys of a duck vagina, but they still have some pretty amazing shape-changing powers. Here’s how they’re put together, and how that anatomy lets them grow when they need to. »
The Age of Exploration brought Europeans riches, a broader view of the world, and a hell of a lot of new plants and animals to describe. That was heaven for Carl Linnaeus, a young Swedish doctor with a passion for plants. »
Human testes are masters of mass production, spitting out sperm at a rate of 200 million per day. But that doesn’t mean the process is fast–it takes 64 days to make a sperm. The organ keeps the count high with an assembly-line anatomy that scales up sperm development from a trickle to a flood. »
Your spam folder is probably full of the offers. (Mine certainly is.) But none of the emails promising to let you “please your partner” by making you a “giant for girls” with “strong erections” say a thing about how the penis gets erect in the first place. Here’s how it really works. »
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.
Sexual selection doesn’t necessarily just shape sexual anatomy – it can have as profound an effect on the rest of an animal’s body as natural selection does. In both cases, the end result is more babies for animals that look or act a particular way. »
If you were a midwife or a doctor attending childbirths during the 17th century, you might have owned a tiny anatomically correct doll like this one. Carved from ivory by German, French or Italian craftsmen, these tiny anatomical manikins opened to reveal the normal arrangement of human organs, including the lungs,… »
Most of us would rather not think about what happens to our bodies after death. But that breakdown gives birth to new life in unexpected ways, writes Moheb Costandi.
Most of the time, the male Superb Bird of Paradise is a fairly nondescript black bird. But when it tries to attract a mate, it flips its feathers around to create a fluorescent kabuki mask that you’ll never forget. In this video, ornithologist Ed Scholes explains how the bird creates the illusion.
If you've ever wondered what the difference between a Kansas City Strip and a Sirloin was, or where the hell the T in your T-bone came from, this video will help. »
Last year, scientists did the wacky and cool thing of making a mouse brain transparent. Now they've gone and done it to an entire mouse by pumping detergent through its veins. The transparent mouse looks like gross rodent jello (yes, there is a photo), but it's also an incredible new way to study what intact organs… »
