  • Pros and Cons of Genetic Engineering in Humans - Part 1

  • The human body is not perfect. Some are created with inherent faults and others break down before their time. Science has the potential to make good these problems by altering how humans are made. This is genetic engineering, and this article looks at the pros and cons of the technology in humans

  • List of Bacteria on the Human Body

  • There is no escape, as they follow you everywhere. Your body is riddled with bacteria. The majority of these microbes are benign, some are helpful, and a few can do us harm. To make the most of our tiny companions scientists have compiled an atlas of bacteria that live in the human body.
