The huge growth stems almost entirely from the religious culture’s high fertility rate, which is about 6 children per woman, on average. At this rate, the Amish population will reach 7
New life form found on Earth: Deadly arsenic breathes life into organisms (Update, Video)
New life form found on Earth: Deadly arsenic breathes life into organisms (Update, Video) by Kerry Sheridan, Arizona State University Scientists have found the first known living organism that incorporates arsenic into the working parts of its cells. What's more, the arsenic replaces phosphorus, an element long thought essential for life. Staff scientist Sam Webb led the research undertaken at the
