Hugo Chavez, the ailing Venezuelan president, is said to be conscious but in a "delicate" situation after a cancer operation..
Vice President Nicolas Maduro denounced rumors the president's health was failing, and said Chavez is aware of the complexity of his condition following a fourth cancer operation in Cuba.

Dull but important:
The United States has been saved at the 11th hour from plunging over the "fiscal cliff." But anxious types still have plenty to worry about: there are a few cliff-like deadlines looming on the horizon.
Have you forgotten about the debt ceiling? It may have slipped under the radar, but US debt hit its legal borrowing limit ($16.4 trillion) on Monday, giving Congress only about two months before it must raise the debt ceiling or risk causing the government to default on its bills and financial obligations.

They're being called the planet's oldest fossils — traces of bacteria that lived a record-breaking 3.49 billion years ago, discovered in Western Australia.
Australia's remote Pilbara region — now an iron ore mining hub — was once shoreline and rocks made from sediment piled up billions of years ago, now exposed and available for examination.
The fossils could help those looking for the building blocks of life on Mars. A paleontologist from Harvard University explained that remnants of life on the Red Planet might even be better preserved than they are on Earth.
Strange but true:
Police in the UK are hunting for a group of people — two of them dressed as Oompa Loompas — who beat a man outside a supermarket in the city of Norwich.
Two males had orange-painted faces and dyed green hair, like the Oompa Loompa characters created by author Roald Dahl and depicted in the 1971 film "Willy Wonka and the Chocolate Factory."
The Oompa Loompas were accompanied by a dark-haired woman in a dress, and a man wearing what the Telegraph newspaper described as "conventional attire."
Police said they were unsure why the attackers were dressed like tiny chocolate workers.
