The continental U.S. experiences small earthquakes every day. But over the past few years, their numbers have been increasing. Geoscientists say the new epidemic of quakes is related to industrial wastewater being pumped into underground storage wells.
Now there's new research that reveals two trigger mechanisms that may be setting off these wastewater quakes — other, larger earthquakes (some as far away as Indonesia), and the activity at geothermal power plants.

Although Heinz may dominate the ketchup scene, 100 years ago it wasn't uncommon to make your own at home. So why bother doing so now, when you can just buy the bottles off the shelf? At least one man, Jim Ledvinka, was motivated by nostalgia.
"Oh, yes — we remember my grandmother making ketchup. And it was quite a sight to behold," Ledvinka says.

And I'm Audie Cornish. Canadian police say they found five more bodies in the rubble of the small village in Quebec devastated by a train explosion on Saturday. That brings the confirmed death toll to 20. And officials say the 30 people still missing are now presumed dead. North Country Public Radio's Brian Mann is on the scene. He joins us now on the line.
America is as much of a melting pot for dogs as it is for their human friends. Walk through any dog park and you'll find a range of breeds from Europe, Asia, even Australia and mutts and mixes of every kind.
But a few indigenous breeds in North America have a purer pedigree — at least one has genetic roots in the continent that stretch back 1,000 years or more, according to a new study. These modern North American breeds — including that current urban darling, the Chihuahua — descended from the continent's original canine inhabitants and have not mixed much with European breeds.
The Central Asian nation of Tajikistan has huge rivers. They begin atop some of the world's highest mountains and then flow west through the country's lush, green valleys. Yet for many Tajik families, getting enough water each day is still a struggle.
