With the skyline of Youngstown, Ohio, in the distance, a brine injection well owned by Northstar Disposal Services LLC is seen in Youngstown on Jan. 4. The company has halted operations at the well, which disposes of brine used in gas and oil drilling, after a series of small earthquakes hit the Youngstown area.
For decades, scientists have known that activities like mining, drilling and building dams can create earthquakes. As early as the 1960s, observers noted that deep-earth gold mining changed the stresses in rocks and caused earthquakes. Above, miners drill into the rock at the Sub Nigel East Gold Mine in Johannesburg in 1961, more than 6,000 feet below ground.
Small earthquakes in Ohio and Arkansas associated with hydraulic fracturing for natural gas have taken many people by surprise. Gas industry executives say there's no hard evidence that their activities are causing these quakes. But some scientists say it's certainly possible; in fact, people have been causing quakes for years.
In the 1960s, geologists realized that gold mines in South Africa had created small earthquakes. Caverns dug into the earth thousands of feet below the surface collapsed. The "pancake" effect caused quakes — in one case a magnitude-5.2 temblor.

The story of how 18-year-old Sarah Dawn McKinley shot and killed a man who authorities say was breaking into her house on Saturday has been getting lots of attention because of the 911 phone call she made and the already tragic circumstances surrounding the incident.
McKinley, of Blanchard, Okla., called 911 to say that a man was trying to get inside her mobile home and that she feared for her life and that of her 3-month-old son. She asked the 911 operator if she could shoot him if he got inside.

Several former rivals of Minnesota Rep. Michele Bachmann were quick to applaud the now-suspended campaign run by the only woman to have sought the 2012 Republican presidential nomination.
Jon Huntsman said Bachmann added an "energetic and passionate voice" to the campaign. Mitt Romney called Bachmann a friend with a "titanium spine." And Newt Gingrich extolled Bachmann's "considerable talent" and "great courage."
In the past two games, Pittsburgh safety Ryan Clark has 18 tackles, 14 of them unassisted. But Clark won't be playing when the Steelers face Denver at Mile High Stadium Sunday, due to his sickle cell trait condition.

When the Pittsburgh Steelers start the NFL playoffs Sunday with a road game in Denver, they'll do it without free safety Ryan Clark. That's because Clark, who has 100 tackles and the confidence of his coaches, also has sickle cell trait, which can cause severe complications at high altitudes.
People without health insurance don't get enough preventive care — simple but important things like vaccinations and blood tests.
But surely having insurance every now and then is better than none at all, because people can get caught up on their tests when they are covered, right?
That's a widely held view, and one that would be good news to the millions of people who go on and off health insurance each year. Some of them are losing or changing jobs. Others slide on and off Medicaid as they take on temporary work, marry or divorce.
Doris Phua, chief executive of Da Vinci, answers questions during a press conference in Beijing in July, after CCTV accused it of selling fake furniture at high prices. Later, the company said it paid the CCTV reporter more than $150,000 through a public relations company to halt further stories.
In July 2011, Chinese state-run TV accused the luxury furniture retailer Da Vinci of passing off made-in-China goods as expensive Italian designer items. Now, a new report in a respected Chinese business magazine, Caixin, says the TV report was full of errors, and Da Vinci says it was blackmailed by the TV journalist.
The Da Vinci furniture company showroom in Shanghai looks like a salon in Versailles. The price tag on a gilt-covered, Italian-made grandfather clock: more than $40,000.
So it was big news last summer when China Central Television — the government's flagship network known as CCTV — reported that some of Da Vinci's ornate furniture didn't come from Italy, but from a common factory in South China.
Robert Carter, who was a key member of the legal team that convinced the U.S. Supreme Court to outlaw segregated public schools in 1954's landmark Brown v. the Board of Education decision, died Tuesday. He was 94.
