Cristo Rey is an island of success in the Catholic ocean. But as in the charter-school community, there is an awareness that there needs to be a system-wide overhaul, lest another thousand-plus schools close over the next decade. "Just because you're devoted to serving others isn't a reason why you can't be operationally excellent," says Eriksen. "That's not really a culture that has permeated the Catholic Church for the last few decades...
Columbus sailed the ocean blue in 1492. On Oct. 12, 517 years later, banks are closed and there's no mail. And despite being a federal holiday, for most in the U.S. it's another day at the office...
...initial excitement was short lived: a helium leak only nine days after the LHC was switched on led to an explosion that postponed data collection along with the careers of graduate students and postdoctoral fellows an ocean away—including several at Harvard. In the next few months, researchers plan to test the LHC a second time, in the hope that their years of hard work will finally help unravel some of the mysteries of the universe...
These scientists aren't the first to look at the chemistry of foraminifera; the fossils are abundant in ancient ocean sediments, so they're a particularly good tracer of the past. But they used a new technique to measure CO2: looking at how much of the element boron was present in the foraminifera's shells. When there's lots of CO2 in the air, there's also more in the top layers of seawater, where the relevant species of foraminifera live. That makes the water more acidic, which in turn makes the tiny animals incorporate less boron into their shells...
...while other scientists take the new result seriously, they're not quite ready to buy into it completely. "It's a really worthwhile and bold effort to understand a period we have a hard time explaining," says Ed Boyle, a professor of ocean geochemistry at MIT. "My cautious view is that this looks promising right now, but I've been studying chemical tracers in foraminifera for pretty much my whole career, and there are often unexpected twists and turns." It is, he says, "the kind of thing where they may turn out to be right, and we'll look back...
