It has been a busy year in Mexico's war on drugs. The administration of former President Felipe Calderon struck major blows to the country's largest cartels, slowing the violence that has claimed more than 50,000 lives.
But the new president, Enrique Pena Nieto, says he'll change tactics. He wants to go after the crime associated with drug trafficking instead of taking down crime bosses. His new attorney general says this is the right strategy, since the number of crime gangs working in the country has grown significantly.
The past year has seen more debate about the best way to find breast cancers.
A recent analysis concluded that regular mammograms haven't reduced the rate of advanced breast cancers — but they have led more than a million women to be diagnosed with tumors that didn't need to be treated.
Every year, banks handle tens of millions of transactions. Some of them involve drug money, or deals with companies doing secret business with countries like Iran and Syria, in defiance of trade sanctions.
But if the Justice Department has its way, banks will be forced to change — to spot illegal transactions and blow the whistle before any money changes hands.
Federal prosecutors have already collected more than $4.5 billion from some of the world's biggest financial institutions — banks charged with looking the other way when dirty money passed through their accounts.
Scientists at the Large Hadron Collider announced the discovery of the Higgs boson on July 4, the long-sought building block of the universe. This image shows a computer-simulation of data from the collider.
It's a year-end tradition to cobble together a list of the most important advances in science. But, truth be told, many ideas that change the world don't tend to spring from these flashy moments of discovery. Our view of nature — and our technology — often evolve from a sequence of more subtle advances.
Even so, chances are good that this year's list-makers will choose the discovery of the Higgs boson as the most important discovery of 2012.

Rescuers carry a sheet to collect body parts near the scene of a bomb explosion in Karachi on Saturday that killed at least six people and . wounded 48. The sandals in the foreground are displayed for sale.
The sad truth about Karachi in 2012 was that whatever your religion, business affiliation, or political party, someone was willing to kill you for it.
The murder rate in Pakistan's largest city and commercial hub hit an all time high last year. Over 2,500 people died in violent crimes in Karachi in 2012, a 50 percent increase over the year before.
Most of the deaths were attributable to sectarian killings and score settling. Shia Muslims took on the brunt of the violence. But Sunni Muslims were killed in reprisal attacks that added to the tally.
It's been a banner year for solar energy. The United States is on track to install a record number of solar power systems — thanks in large part to low-cost solar panels from China. That's been challenging for American manufacturers, and federal officials have put trade tariffs on Chinese panels.
Things look busy at the SunPower solar manufacturing plant in Silicon Valley. Workers are screwing frames onto shiny, 6-foot solar panels as they come off the line.

Leaders from both parties in the Senate came together to reach an agreement that passed with overwhelming bipartisan support today that protects 98 percent of Americans and 97 percent of small business owners from a middle class tax hike.
