There’s a new commander on this sandy, swampy spit of land that has transformed rawboned recruits into macho Marines for nearly a century. Brig. Gen. L.E. Reynolds, a 6-foot-tall Baltimore native and a veteran of Iraq and Afghanistan, is the latest in a long line of no-nonsense leaders to take charge here.
But she’s the first woman.
And for the tradition-bound Marine Corps, which endlessly promotes a tough-guy image and built its recruiting on the search for “a few good men,” the idea of all those ruthless Parris Island drill instructors having to salute a leatherneck named Loretta could take some getting used to.
Visualized: A School Day as Data

By putting RFIDs on children and monitoring their interactions over a single day, researchers have produced one of the most detailed analyses ever of the roiling, boiling social free-for-all that is school.
The findings, published August 16 in Public Library of Science One, document the minute-by-minute interactions and locations of 232 children aged 6 to 12 and 10 teachers.
Reconfigured as pulsing network maps and flows of color are the universal experiences of middle school: the between-class rush, playground cliques, snatched hallway conversation and the fifth-graders who are too cool for everyone else.
“We can compare different types of assumptions or modeling with a model that takes into account all interactions,” said Alain Barrat, who studies complex networks at the Institute of Scientific Interchange in Turin, Italy.

For epidemiologists, these visualizations — which focus on face-to-face interactions during which a hypothetical pathogen could jump from one person to another — aren’t just pretty pictures. They could inform better models of disease spread and perhaps guide school closures during outbreaks.
Researchers can also investigate different outbreak control strategies. Perhaps it’s not necessary to close entire schools, but only specific classes, to slow a contagion’s spread. “Shifting some schedules by 10 to 15 minutes could be enough,” Barrat said.
According to Barrat, some aspects of their data will be particular to the Lyon, France school where it was gathered, but the essential dynamics are likely universal.
