Weird science

• Technically, Macie McCartney was born on May 3 of this year in Laredo, Texas, but that appearance outside the womb was actually her second. When a large tumor showed up on Macie six months into her mother's pregnancy, surgeons actually pulled the fetus almost completely out of the uterus so they could excise the growth and then re-inserted the fetus. Following that rare procedure, the birth was normal, according to Dr. Darrell Cass, who explained it in June to viewers of NBC's "Today" show.

• Evolution scientists at Switzerland's University of Lausanne reported in June that over the course of 30 to 40 generations, ordinary flies tend to live longer if they're stupid. The researchers guessed that heightened neural activity overtaxed their systems.

• Cardiologists at Hartford (Conn.) Hospital, writing in the June Annals of Emergency Medicine, described a patient suffering from irregular heartbeat whose rhythm was restored to normal following a Tasering by police.
