The Large Synoptic Survey Telescope, seen in this artist's rendering, will be built on the peak of the Cerro Pachon mountain in Chile and will survey every patch of the night sky. The data the telescope will collect will allow researchers to "answer fundamentally different questions about the universe," says one astronomer.
Every 10 years, about two dozen of this country's top astronomers and astrophysicists get together under the auspices of the National Research Council and make a wish list. The list has on it the new telescopes these astronomers would most like to see built. At the last gathering, they said, in essence, "We most want the Large Synoptic Survey Telescope."
Here's why. A synoptic survey is a comprehensive map of every square inch of the night sky. The Large Synoptic Survey — LSST — will do that multiple times.
The northern plains, especially the Dakotas, are home to about half of the country's honey bee hives during the summer. It's been a good place for bees because they can gather nectar and pollen from so many wildflowers.

Melissa Block speaks with Eric Heginbotham — senior political scientist at RAND — about China's military capability today, how it's developed over time and what the Chinese make of ramped-up attention from the US.
An Egyptian soldier on an armored vehicle guards an exchange office in Cairo on Monday. Tensions between the U.S. and Egypt are rising over Cairo's investigation of aid workers, many of them American. An Egyptian Cabinet minister, Faiza Aboul Naga, recently accused the U.S. of directly funding pro-democracy groups in order to create chaos in Egypt.
Sometimes I wonder: Do the members of young indie-rock bands know that they're walking stereotypes? There's the scruffy dude who's obsessed with everything vintage and analog, the Pavement-worshiping, whiny-voiced lead singer, the rhythm section that knows its way around every oddity recorded by The Kinks. That's pretty much how I pegged the Philadelphia sextet Dr.
