Back in 1958, a young biologist at Cornell University made a stunning discovery.

He took a single cell from a carrot and then mixed it with some coconut milk. Days went by and the cell started dividing. Little roots formed. Stems started growing. Eventually, a whole new carrot plant rose up from the single cell.

Imagine if you could perform a similar feat with animal cells, even human cells.

Scientists have reconstructed the genetic code of a strain of bacteria that caused one of the most deadly pandemics in history nearly 1,500 years ago.

They did it by finding the skeletons of people killed by the plague and extracting DNA from traces of blood inside their teeth.

This plague struck in the year 541, under the reign of the Roman emperor Justinian, so it's usually called the Justinian plague. The emperor actually got sick himself but recovered. He was one of the lucky ones.

It would have been hard to find a happier man than Erick Munoz on that Tuesday morning before Thanksgiving.

With a healthy and delightful son toddling around the house, and his beautiful and successful wife pregnant with their second child, the fire department paramedic had everything in life that's really important. So it must have been with a feeling of disbelief and horror that Munoz knelt across the nearly lifeless body of his wife, Marlise, on the kitchen floor at 2 a.m., his fingers linking across her heart, arms pumping away in vain.
