Thirty years ago this week, President Ronald Reagan's administration released "A Nation at Risk," a report warning of "a rising tide of mediocrity" in American public education.
According to the report, only one-third of 17-year-olds in 1983 could solve a math problem requiring two steps or more, and 4 out of 10 teenagers couldn't draw inferences from written material. In an address to the nation, Reagan warned that "about 13 percent of 17-year-olds are functional illiterates and, among minority youth, the rate is closer to 40 percent."

But our fears quickly turned to fascination.
Johns Hopkins engineers are testing out what they call "untethered microgrippers" as a better way to investigate hard-to-reach places. They have launched hundreds of these things, which look like miniature ninja throwing stars, inside the body of animal to retrieve tiny pieces of tissue for biopsies.
