Abstract

The intrepid Curiosity rover has burst into song, and famed astronaut Neil Armstrong has died. Meanwhile, an Internet fundraiser has raised more than $1 million to build a museum to honor eccentric Serbian-American scientist Nikola Tesla. And this week's numbers quantify the cost of a trial to test whether an anti-inflammatory medication prevents cardiovascular disease, measles cases in England and Wales in the first 6 months of 2012, and likely American voters who think that Indian and Chinese schools are catching up to, or have surpassed, K–12 schools in America.
