Echidnas are one of those weird Australian animals that seems to have been pieced together from leftover bits of other animals. Mammals that lay eggs, echidnas are covered in pointy hedgehog-like spines, but with a long snout and sticky tongue of an anteater.
Also, the males have a four-headed penis.
Not kidding. One shaft, four heads. Which is odd, because the female echidna reproductive tract only has two branches. Some of the stuff I've read this morning says that the male echidna mates using only two of his four heads at a time. Then, he'll find another lady echidna and let the other two heads have a turn. Another option, presented by National Geographic: He mates twice with each lady echidna, using first two heads, and then the other two.
National Geographic has helpfully provided visual evidence of this four-headed penis.
I'm putting the photo under a cut. Partly for comic effect, and partly because what is seen can never be unseen.
Read the rest of the National Geographic article on the lives and weird biology of the echidna. (That's the only penis shot. Promise.)
Anthony Atala, director of Wake Forest University’s Institute for Regenerative Medicine, is developing techniques to 3D print human organs for transplant using an individual’s own cells as the “ink.” That way, the transplanted organ won’t trigger the patient’s immune system to reject it as a foreign body. From National Geographic: (For example,) to create an […]
A Scottish team of animal biotechnologists announced this week they successfully introduced human stem cells into sheep embryos. Perhaps one day we will all have our very own baaing organ donors. The team are currently allowed to let the chimeric embryos develop for 28 days, 21 of which are in the sheep. While that might […]
I can’t believe I have to write this, but maybe jamming other people’s shit up your ass isn’t a great idea. When done by medical professions, under very specific circumstances, a fecal transplant can mean the difference between life and death: implanting feces containing healthy gut microbiome into a patient’s body has been used by […]
Python is one of the most popular and versatile programming languages used by developers today, making it an ideal first choice for those looking to kickstart a career in programming. While you could go back to school or sign up for a pricey coding bootcamp, you can learn the essentials of coding with Python at […]
Going back to school isn’t necessarily an option for everyone. Between the time commitments and steep tuition rates, there are obstacles aplenty as far as furthering education is concerned. However, that’s not to say it’s impossible to learn new skills. Excel with Business lets users access thousands of hours of online learning in Microsoft, business, technology, […]
More often than not, you won’t see an accident coming, which means it pays to be proactive and ensure you have the right tools on-hand before you need them. Whether you find yourself in the middle of a power outage or having car trouble at night, you can make sure you’re still capable of navigating […]
