    Scientists Have Created “Spermbots,” Which Are Exactly What You Think They Are

    Get your robot-proof tube socks ready, internet, because science has started to mechanize sperm. By combining your little swimmers with nanotechnology, scientists are hoping these "spermbots" could be used for fertilization - or, to deliver targeted doses of microscopic medicine.

    Cells Trapped in Nanoscale Pyramids for Study in 3D

    Researchers looking for new insights on how cells interact in three dimensions have a new tool for their studies -- nanoscale pyramid structures with open sides. These new structures allow researchers to capture individual cells for study, while still exploring how those cells interact with their surroundings and with other cells.

    Laser The Size Of A Virus Uses Nano Bow Ties To Create Tiny Laser Beams

    Northwestern University researchers can put a tiny little feather in their hat today as they have announced the creation of the world's smallest working laser -- one about the size of a virus. The incredibly miniaturized laser can operate at room temperature, and, even more impressively, seems to defy the diffraction limit of light using a nano-scale laser cavity that's shaped like a bowtie. Bill Nye must be so very proud right now.

    Laser Guidance Allows 3D Printing on Molecular Scale

    3D printing is getting easier, more cost effective, and more household friendly every year. Some of its most impressive applications, though -- like its potential in the world of medicine -- won't be making their home debuts anytime soon. This is because while printing, say, a Mario statue in your Makerbot is very simple, printing things on a nanometer scale is still very hard. Doable, but very, very hard. Researchers at the Vienna University of Technology have made a step toward simplifying that task, though, using a laser beam to place single molecules on structures just a few nanometers wide.
