It's good to know science is so infallible.

"CHAPEL HILL...researchers have discovered genetic variations in the most widely used strains of laboratory mice are vastly greater than had been thought."

Probably not a big difference, though, considering the fact that we can tell mice apart from each other by fairly basic means, right?

"The Jackson Laboratory...said previously only 140,000 variations in DNA sequence in such mice were described. The new study suggested...8.3 million such variations."

Oh...well...go us.

Now back to work on that Cancer business!
