Good news for people who fear they may have sexually transmitted diseases (STDs). A Clinical Research Collaboration team at the University of London is currently developing a computer chip that can tell you whether or not you have an STD, including herpes and gonorrhea, There is one catch, however. You have to urinate or spit on the chip. Then the chip can be plugged into a phone for the analysis,

The chips will probably be the size of a USB chip and may be sold in vending machines for around 80 cents to $1.60. Many folks are applauding this new development since it will encourage more people to perform self-exams and could reduce the spread of STDs.
