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.
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.
2012 will go down as a year of orchestral turmoil in the U.S.: Strikes, lockouts and bankruptcies erupted time and again as once seemingly untouchable institutions struggled financially.
There's been particularly little seasonal cheer in Minnesota's orchestral community. Protests erupted after management at the Minnesota Orchestra and the Saint Paul Chamber Orchestra each locked out their musicians, after the musicians had rejected contracts that cut their salaries by tens of thousands of dollars and reduced the size of the orchestras.
