We Thought These Microscopic Invertebrates Never Had Sex. Maybe We Were Wrong.

Chances are, you’ve never heard of bdelloid rotifers, strange microscopic creatures that typically live in freshwater ponds and streams. In the grand scheme of things, they’re related to arthropods, a group which includes insects, spiders, and crustaceans. But honestly, they’re in a unique class all their own.

Google Makes It Easy to Find Sex Inventions in the US Patent Database

Inventors have been coming up with devices to improve sex for decades. But before Google digitized all the records of the US Patent and Trademark Office to launch their Patent Search feature, if enterprising creators wanted to check whether their ideas were truly original, they had to search the sex patents by hand. »9/01/15 4:40pmTuesday 4:40pm

Here’s Why We’re Not Overrun With Adorable Baby Giant Pandas

The Smithsonian’s National Zoo has been part of an international effort to breed highly endangered giant pandas in captivity ever since Richard Nixon visited China in 1972. But in 43 years, they’ve had only two solid successes–cubs Tai Shan and Bao Bao. They hope the new twins born this weekend will make it four. »8/25/15 11:00am8/25/15 11:00am

How Lurking Predators Changed the Size of the Mosquitofish's Genitals

Female mosquitofish give birth to tiny babies, like the guppies you may remember from your third-grade aquarium. That means male mosquitofish don’t spawn: if they’re going to be dads, they need to use a modified fin (called a gonopodium) to inseminate their mate. And sex with a long, stiff fin demands a daunting level… »8/25/15 8:00am8/25/15 8:00am

When You Have an Orgasm for No Reason

Imagine you’re playing a video game, maybe walking somewhere, basically minding your own business when the orgasm arrives. No arousal, no physical stimulation, no buildup, no control: just an instantaneous shift from status quo to woaaah. It’s called an orgasmic seizure. Here’s what scientists are learning from people… »8/18/15 11:30am8/18/15 11:30am

The Unusual Mating Habits of This Octopus Totally Blow Biologists' Minds

We all know the sad story of octopus sex, right? They live alone until it’s time to find a mate, they have sex a few times, then the males die. Females live a little longer to lay eggs, but die soon after they hatch. Turns out that the (still officially unnamed) Larger Pacific Striped Octopus breaks all the rules. »8/12/15 2:00pm8/12/15 2:00pm

Here is a Cactus Bribing a Bat to Help it Have Sex 

The deep, bell-shaped flowers of the saguaro cactus use a strong melony scent to tell the bats that pollinate them they’re open for business, but they hide the nectar the bats want to lick up deep inside their base. If the bat wants to eat, it has to shove its face into the dozens of pollen-covered anthers inside the… »8/06/15 10:00pm8/06/15 10:00pm

Australia's Most Infamous Invasive Species Has a Problem with Breeding

Cane toads were first released in Australia in 1935 as part of a government program to control the insects attacking the Queensland cane crop. It didn’t work. Ever since, the toads have been spreading across the country, as fast as they can breed. Which would be even faster, if it weren’t for an odd quirk in their… »7/14/15 4:15pm7/14/15 4:15pm
