Venezuelan President Hugo Chavez, who has been battling cancer for months, is in a "very delicate" condition, with breathing difficulties and a severe respiratory infection, a government statement says.
The statement, read out Monday by Minister of Communications Ernesto Villegas, spells out the 58-year-old socialist leader's decline since his December surgery in Cuba for an unspecified cancer in the pelvic area:
That's not a real bishop on the left: A man later identified as Ralph Napierski of Germany (at left) posed with Cardinal Sergio Sebiastiana and others on Monday at the Vatican. Napierski was an imposter. He was later escorted from the area by Swiss Guards.
Now that the sequester has taken effect, there's a new phrase that keeps popping up in Washington: the "continuing resolution." If Congress doesn't pass a continuing resolution by March 27, the government will run out of money and will likely shut down. Here's a list of four things you might want to know about how a continuing resolution works and how it might soften the blow of the sequester.
This image represents a chunk, or "cube," of brain. Each different color represents a different neuron, and the goal of the EyeWire game is to figure out how these tangled neurons connect to each other. Players look at a slice from this cube and try to identify the boundaries of each cell. It isn't easy, and it takes practice. You can try it for yourself at eyewire.org.

Daniel Berger, a researcher at MIT, traced these neurons using the EyeWire game.
In the EyeWire game, participants identify different neurons by coloring in their shapes using a Web-based 3-D interface.
People can get pretty addicted to computer games. By some estimates, residents of planet Earth spend 3 billion hours per week playing them. Now some scientists are hoping to make use of all that human capital and harness it for a good cause.
Right now I'm at the novice level of a game called EyeWire, trying to color in a nerve cell in a cartoon drawing of a slice of tissue. EyeWire is designed to solve a real science problem — it aims to chart the billions of nerve connections in the brain.
