This week, "Where Are They Now?" columnist Laura Vanderkam and managing editor, online, Ivan Oransky, are in Atlanta for the Intel International Science and Engineering Fair. ISEF is an annual event that seeks to show off the best of high school science. Sponsored by Intel—which also sponsors the Science Talent Search whose past finalists we started profiling this week—it draws 1,500 students from 51 countries to a host city to show off their work. The kids compete for $4 million in scholarships and awards.
