Scientific American.com's 60-Second Science blog is now called "Observations" and begets 4 additional blog categories

The 60-Second Science series was created with the intention of providing our audience with bite-size, consume-in-one-minute pieces of scientific coverage. This format has proved ideal for our podcasts, but we've missed the option to write longer news and opinion pieces for the blog. We also wanted a way to better highlight the themes that have emerged within the 60-Second Science blogs. The editors put their heads together and the final result is the introduction of five ScientificAmerican.com blog categories:

1. Observations: Opinions, Arguments & Analyses from the editors of Scientific American
2. Bering in Mind: A Research Psychologist's Curious Look at the Human Mind
3. Extinction Countdown: News and Research about Endangered Species from around the World
