Each year, 17,000 people receive a kidney transplant, but it's the number of people that don't receive one that is so astounding.
THAT number is about 17,000 people times FIVE, which is why news that scientists have made functioning rat kidneys at Massachusetts General Hospital in Boston is SO amazing!!!!
When the kidneys were transplanted into rats - they effectively produced urine for the rodents!
Normally rat urine isn't very exciting, but this could be a first step towards creating replacement organs for folks who suffer from kidney diseases.
