The hunt for an effective, reversible, and socially acceptable male birth control continues. The newest target: The smooth muscle that makes up the tubes connecting the testes to the urethra. This needs to contract in order for sperm to reach their final destination. Now, scientists have shown that you can make mice sterile by eliminating their ability to contract that muscle. The result: A mouse with a dry ejaculation but which is still "pelvis thrusting with appropriate vigor and frequency".
This is a long way from becoming reversible treatment for human gentlemen, though. Right now, probably the most promising male birth control is RISUG, in which a clear polymer gel is injected into the vas deferens. The gel doesn't block the tube up completely, but it does seem to prevent sperm from successfully reaching the urethra and being capable of fertilizing an egg. RISUG is in Phase III clinical trials in India, but, even then, there are still safety questions about it and, so far, it's only been proven to be reversible in tests on non-human primates.

Repeating the word “fuck” actually can reduce your experience of pain, according to a new study by Keele University researchers. The psychologists ran an experiment in which subjects underwent a cold pressor test, a common method to pain threshold and tolerance by immersing your hand in freezing cold water for a minute.

These are just two of the most common experiences that people report after a near-death experience (NDE). For some people, NDEs are a transformative […]

Promoting products is almost nothing like it was back in the Mad Men days. In fact, the digital landscape has changed the ad game so much that it barely even resembles early Grey’s Anatomy days anymore. Marketing a product digitally isn’t about the right ad slogan or color scheme. It’s about crafting the narrative around […]
Every once in a while, we see a new product come along that’s so versatile and elegantly simple that it’s strange no one’s ever gone there before. Portable lights themselves aren’t new, but there’s something about the MOGICS Coconut Light that’s so seamlessly well-designed and adaptable that it feels startlingly original. The Coconut is basically […]
With the U.S. cautiously reopening, it’s probably time to take stock of where you’re at. After spending all these weeks in the house, you’ve likely already assembled a little list of items you either realized you were missing or need to replace. And those kinds of revelations probably apply to nearly every room. We got […]
