Science students get stars in


BY ERIC NIILER Special to The Washington Post When the giant Green Bank Telescope


inWest Virginia got stuck in one position a few years ago, astronomers collected a big pile of electronic data from one part of the sky but had nobody willing to sift through it. So they did what many of us do for


boring chores: They found some teenag- ers. They set teams of high school science


students to scanning thousands of com- puterized “star plots” in search of pul- sars, blinking beacons of deep-space ra- dio energy that offer clues to the makeup of the universe. It’s been a galactic trea- sure hunt, and twostudents have already hit the jackpot. One was Shay Bloxton, a junior from Summersville, W. Va., who discovered a pulsar last October. “WhenI first sawit, I didn’twantto get


my hopes up,” Bloxton said. “Then they confirmed it a few weeks later, and I was really excited.” To find that pulsar, Bloxton spent


hours at herhomecomputer usingdown- loaded software that translates the data gathered by the telescope into graphs. The graphs describe the strength, fre- quency and distance from Earth of a source of radio energy; a series of graphs makes up a star plot. “I looked through 2,000 individual


plots before I found one,” Bloxton said.“You have to be able to understand a bit of science andwhat a pulsar is. It’s not extremely difficult, but it takes a while.”

cientists are broadly rethinking the nature, skills and demise of the Neanderthals of Europe and Asia, steadily finding more ways that they were substantially like us and quite different from the limited, unchanging and ultimately doomed inferiors most commonly described in the past. ¶ The latest revision involves Neanderthals who lived in southern Italy from about 42,000 to 35,000 years ago, a group that had to face


fast-changing climate conditions that required them to adapt. ¶ And that, says anthropologist Julien Riel-Salvatore, is precisely what they did: fashioning new hunting tools, targeting more-elusive prey and even wearing identifying ornaments and body painting. ¶ Traditional Neanderthal theory has it that they changed their survival strategies only when they came into contact with more-modern early humans. But Riel-Salvatore, a professor at the University of Colorado at Denver writing in the Journal of ArchaeologicalMethod and Theory, says that was not the case in southern Italy. ¶ “What we know is that the more-modern humans lived in northern Italy, more-traditional Neanderthals lived in middle Italy, and this group that adapted to a changing world was in the south—out of touch with the northern group,” he said.
