Muruganantham's story of invention took more than four years and, at one point, got him branded as a pervert when neighbors caught him wandering around the village with a football bladder full of goat's blood under his clothes (part of an attempt to test the absorption rate of different materials).
You can read about him on Slate, or watch him tell his own tale in a talk at TEDxBangalore. Here, truly, is a man with a good attitude towards menstruation.
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
