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.

Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
One million miles from Earth, hanging in space between Earth’s gravitational pull and the sun’s, is the DSCOVR satellite and NASA’s incredible EPIC camera. Every two hours, EPIC takes a photo of Earth “to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.” The above video […]
In Botswana, conservation scientists from the University of New South Wales are painting eyes on the rear ends of cattle in an effort to deter lions from eating them. As the lions’ protected habitats shrink, they move closer to human settlements. In Botswana, the lions attack the livestock that the subsistence farmers count on. That […]
