Layers of lake sediment are removed at intervals from a core. In a laboratory, contaminants and biological remains are analyzed from select sediment layers to understand lake history and reconstruct environmental changes that often predate periods of direct monitoring.
Canadian researchers have used the mud at the bottom of lakes like a time machine to show that tar sands oil production in Alberta, Canada, is polluting remote regional lakes as far as 50 miles from the operations.
An increasingly large share of U.S. oil comes from Canada's tar sands. There are environmental consequences of this development, but until recently, Canadian regional and federal governments left it to the industry to monitor these effects.
U.S. employers added 155,000 jobs in December, a steady gain that shows hiring held up during the tense negotiations to resolve the fiscal cliff. But the unemployment rate remained at 7.8 percent last month.
Businesses complained that the uncertainty surrounding the "fiscal cliff" froze their decisions about hiring and expanding, which hurt the economy. Washington has now managed half a deal, which settles tax issues, at least for the time being. But has that removed enough uncertainty to boost some business hiring and investment?
Beit Qamishlo is a modest house in southern Turkey that caters to Syrian exiles seeking temporary refuge. It also hosts frequent discussions on Syria's future. Here, Malik Dagestani (center), a former political prisoner in Syria, talks about his detention in the 1980s and 1990s.
It's called Beit Qamishlo, or the House of Qamishlo. It's named after a city in northeastern Syria, though the house isn't even in Syria — it's just across the border in southern Turkey.
The house is humble, made of concrete blocks, with tile floors. Arabic slogans are taped on the walls: "Beit Qamishlo is a house for everyone," "It's a window to Syria's future," "Under one roof we plant life together and freedom."
