How Do Sperm Recognize Eggs? Mechanism Finally Found
It’s the stuff of 3rd-grade sex ed: sperm meets egg to make baby. But, surprisingly, scientists have actually been in the dark about one crucial step: how the two sex cells recognize each other amidst the fluid frenzy in the Fallopian tubes. Now researchers have announced that they’ve found the missing piece of this fertilization puzzle, and that the discovery could lead to individualized fertility treatments and hormone-free birth control. Back in 2005, researchers found the first half of the the puzzle: a binding protein on the surface of sperm they called Izumol (after a Japanese marriage shrine). In the decade since then, scientists have been searching for Izumol’s counterpart on egg cells. Essentially, they’d found the plug but couldn’t locate the outlet. Today researchers at Cambridge announced they’ve found that outlet: a receptor protein on the surface of the egg cell. They’ve found it on the eggs of pigs, opossums, mice and even humans.

Haus in Schwarz (House in Black)
In the city centre of Möhringen, Germany, used to stand an unusual house that was painted completely black.
It was a 2008 public art piece by artists Erik Sturm und Simon Jung.
The piece was meant as a farewell to the building which was slated for demolition.
The black paint represented a curtain for the house, whose exterior had been used as a canvas by numerous street artists.
After it was demolished, the owner, art gallery manager Karin Abt-Straubinger, built a new gallery on the site.
The noble house of Black.
