Throughout history we've blushed and called it la petite mort, the sting of pleasure, the balsamic injection, the flood of bliss?the list continues. But let's cut to the chase: I'm talking about ejaculation.It's almost seems as if some deep-seated Puritanical modesty compels us to semantically sidestep addressing this perfectly natural function. Perhaps we're just a bit bashful that it feels really, really good. It's not polite to discuss such scrumptious pleasures publicly.Humans ar

The City Nature Challenge hopes to change that.What is the City Nature Challenge and how did it star
Diamond is the hardest natural material, but now scientists have shown that it can bend and stretch, much like rubber, and even elastically snap back into shape ? even if it only happens with diamonds that are very small. Such flexibility could open up a wide new range of applications for diamond, the researchers say.Diamond is extraordinarily hard, meaning it excels at resisting any change to its shape ? that's why a diamond can cut through softer materials and will only be scratched by
The average cow needs cranial surgery like it needs a hole in the head, but for one ancient bovine, it appears that's exactly what the doctor ordered.Researchers describing a hole in the skull of a Neolithic cow say it's possibly the earliest example of veterinary surgery ? though it may have also been mere practice for performing the procedure on a human patient.Trepanation, or the act of intentionally making a hole in the skull, has a long history in our species (and it's still o
