President Obama has led an administration that so far has avoided a headline-grabbing, signature scandal. But now he's learning how one begins to take shape.
In many ways, the Benghazi story is following the arc of many Washington scandals of the past. It's rarely the initial incident that gets politicians in trouble. Instead, it's the way in which they respond to it.
The U.S. District Court judge who last month ordered the Food and Drug Administration to make the most popular forms of the emergency contraceptive pill available over-the-counter with no age restrictions has denied the government's request to stay his ruling while it's on appeal.
Researchers use the 120-foot tower atop Mauna Loa in Hawaii to collect air samples and measure the amount of carbon dioxide in the atmosphere. Mauna Kea looms in the distance.

Aidan Colton is a research scientist at the Mauna Loa Observatory. Here in the "carbon cycle room," he measures the amount of carbon dioxide, methane and carbon monoxide in air from intake ports at the top of a 120-foot tower outside the lab.
Climate scientists have a good reason to want to get away from it all. To get an accurate picture of the amount of carbon dioxide in the Earth's atmosphere, you have to find places where the numbers won't be distorted by cities or factories or even lots of vegetation that can have a major local impact on CO2 concentrations.
Boston Marathon bombing suspect Tamerlan Tsarnaev has been interred at a Muslim cemetery in central Virginia after a two-week ordeal in which a Massachusetts funeral director sought in vain to find a burial location.
A supporter greets Imran Khan at a campaign rally on May 6, in Multan, Pakistan. Pakistan's parliamentary elections will be held on Saturday, and Khan's party is hoping the large, enthusiastic crowds at rallies will translate into a strong showing at the polls.
Children with autism see simple movements twice as fast as other children their age, a new study finds.
Researchers at Vanderbilt University and the University of Rochester were looking to test a common theory about autism which holds that overwhelming sensory stimulation inhibits other brain functions. The researchers figured they could check that by studying how kids with autism process moving images.
Rarely a month seems to pass when there isn't some state legislator in New York facing indictment.
The latest, former Democratic state Sen. Shirley Huntley, was sentenced Thursday to spend a year and a day in prison for stealing $88,000 from a charity she controlled. A day earlier, a federal judge had unsealed records showing that Huntley last year secretly recorded conversations with seven other elected officials she suspected of corruption.
Carbon dioxide readings at the Mauna Loa Observatory in Hawaii have reached what atmospheric scientist Ralph Keeling calls a "psychological threshold" of 400 parts per million. The amount of carbon dioxide in the atmosphere has been steadily increasing since near-constant measurements began at the observatory in 1958.

Pat Lang, of NOAA in Boulder, Colo., measures the amount of greenhouse gases from an air sample. The Boulder lab is part of a global network of air-sampling laboratories that track carbon dioxide levels in the atmosphere.
Earth's atmosphere is entering a new era. A mountaintop research station that has been tracking carbon dioxide for more than 50 years says the level of that gas in our air has reached a milestone: 400 parts per million.
That number is one of the clearest measures of how human beings are changing the planet. It shows how much carbon we have put into the air from burning fossil fuels — and that carbon dioxide drives global warming.
This measurement comes from Mauna Loa, Hawaii, a remote volcano where the air is largely free of local influences.
