Scientists would like to know more about how cells work. But seeing what's happening inside a cell isn't easy. It's dark in there, and even if you shine a light, many of the critical chemical reactions are invisible.
Now, a team of researchers has found a way to reveal the invisible by attaching what amounts to a reflective tag to a chemical called RNA, a close relative of DNA. Molecules made of RNA have a variety of important jobs inside cells and frequently, doing those jobs requires the RNA to shuttle from one part of the cell to another.

"As soon as the House completes its vote tonight, the Senate will move to take up that bill. It will be defeated," Reid said on the Senate floor.

Drug dealers and methamphetamine cooks in Logan County are taking advantage of funding cuts and manpower shortages at the South Central Kentucky Drug Task Force and the Russellville Police Department. The task force that investigates drug crime in Logan and Simpson counties is down from six investigators to four, and funding has been cut for the second straight year, hindering efforts to track and prosecute drug dealers.
A survey of 55 skulls from the 1800s and regions across the globe finds that people who lived in high latitudes had bigger eyes and brains. Researchers at Oxford University say the variations are not due to differences in intelligence but are instead related to ambient light:
Rep. Todd Akin's constituents want to see a deal putting an end to the debt-ceiling debate, but not just any deal.
Despite party pressures, the Missouri Republican is planning to vote against Speaker John Boehner's latest proposal to lift the debt ceiling. It doesn't do enough to "address the spending problem," according to Akin's spokesman Steve Taylor.
