NASA spots caves on Mars
An orbiting spacecraft has found evidence of what look like seven caves
on the slopes of a Martian volcano, the space agency NASA said on Friday.
The Mars Odyssey spacecraft has sent back images of very dark, nearly
circular features that appear to be openings to underground spaces.
"They are cooler than the surrounding surface in the day and warmer at
night," said Glen Cushing of the US Geological Survey's Astrogeology Team
and Northern Arizona University. "Their thermal behavior is consistent
with these being deep holes in the ground."
McDonald's surprise comeback
It wasn't so long ago that the McDonald's fast-food empire looked stale.
Sales were decreasing, new products weren't catching on and McDonald's
was vilified by consumer activists, nutritionists and others as Americans
got fatter and fatter.
Now, thanks to a combination of improved menus, better marketing and deft
management, business is cooking like never before.
The comeback may not be news to anyone who has queued up at a McDonald's
drive-through recently. But the fact that the sales resurgence not only
continues to sizzle is a surprise to experts who had expected the burger
chain to sink without a trace.
