Large-Scale Differences Discovered in DNA of Healthy People
Ever since the human genome was sequenced in 2001, scientists interested in medicine have focused on small,

Now, seemingly all of a sudden, two groups of scientists working independently have discovered that healthy people
have huge chunks of DNA that are repeated over and over, for no known reason, and also huge chunks of DNA that are
missing, also for no known reason.
