genetic testing

Amniocentesis and chorionic villus sampling remain the gold standard for detecting genetic abnormalities such as Down syndrome in a developing fetus. But because these procedures are invasive and can cause miscarriage, their use is normally only advised for women with known risk factors. Now a handful of emerging tests suggest that in the near future, it may be possible to detect genetic defects with a simple blood draw from the mother.

Your DNA falls into the realm of "the world's information," and it seems that Google (GOOG), as part of its corporate mission, is making a play to organize that, too. The Internet giant received heavy press in 2007 when it invested at least $4.4 million (BusinessWeek.com, 11/29/07) in a genetic screening company, 23andMe, that was started by Anne Wojcicki, the wife of Google co-founder Sergey Brin, and her business partner.

Assuming you believe it's okay to abort a fetus who would grow up with a severe disease or disability, using genetic screening to test fetuses for such defects is probably acceptable. But what about tests for conditions that might not be severe?
