Have you heard? Scientists have discovered a drug that cures Down syndrome with a single injection! Only they haven't. They've cured Down syndrome in mice with a single injection. Except... well... they haven't really done that, either.
Science has done an awful lot for mice. Cancer, Huntington's disease, old age, HIV. You don't worry about these things if you're a mouse, because science is on it. The latest breakthrough: yesterday, researchers published the results of a new treatment that has since been reported far and wide as a "cure" for or "reversal" of Down syndrome (in mice). These are, as is often the case with such claims, gross misrepresentations of the actual findings.
