Mars, seen in this composite image, has a lot of water in its polar ice caps. If water is also trapped in the planet's crust, experts say, it could house microbial life.
Scientists have discovered water that has been trapped in rock for more than a billion years. The water might contain microbes that evolved independently from the surface world, and it's a finding that gives new hope to the search for life on other planets.
The water samples came from holes drilled by gold miners near the small town of Timmins, Ontario, about 350 miles north of Toronto. Deep in the Canadian bedrock, miners drill holes and collect samples. Sometimes they hit pay dirt; sometimes they hit water, which seeps out from tiny crevices in the rock.

Bees, after all, could build honeycombs from rectangles or squares or triangles ...
But for some reason, bees choose hexagons. Always hexagons.

The company that owns the Bridgeton Landfill is offering to cover the cost of hotel stays for nearby residents who want to get away from the smell.
On Tuesday, Republic Services sent a letter to 270 households within a one-mile radius of the landfill, saying the company would pay for residents to move to a pet-friendly hotel between May 20 and June 14.
