Snow hung on pine branches as Flagstaff’s Marine Color Guard honored Arizona’s centennial this morning at the Pioneer Museum.

Locals visited the museum throughout the day where a new Centennial exhibit is on display.

The exhibit is a preview of a larger exhibit planned for the spring.

It will showcase each decade of Flagstaff’s history.

Sixty eight-year-old color guard member Johnny Anaya was born and raised in Flagstaff.

He says his favorite memories are of the Flagstaff All-Indian Powwow, which occurred every Fourth of July between 1929 and 1980.

Joe Meehan and Les Roe rang the Emerson School bell at Flagstaff Pioneer Museum 100 times to mark Arizona's 100th birthday Tuesday.

The museum is hosting a day-long birthday party with a new Centennial exhibit by NAU history students.

Meehan, curator of Arizona Historical Society’s Pioneer Museum, says in 1912, Flagstaff was a booming frontier town with a population around 2,000.

“The lumber yard was up and running. It was growing, the university was here, the observatory was here,” he says.

The northern plains, especially the Dakotas, are home to about half of the country's honey bee hives during the summer. It's been a good place for bees because they can gather nectar and pollen from so many wildflowers. But the landscape of the area is becoming less bee-friendly, and the consequences could be felt as far away as the almond groves of California, which depend on those same bees for pollination.

If you've ever had a painful sinus infection, all you want is relief — fast!

So off to the doctor you go, and, as often as not, you get a prescription for an antibiotic.

Three days later, you start to feel a little better. "Thank goodness for amoxicillin!" you might say. Well, probably not quite like that, unless you're a nerdy health blogger, but you'd be saying something nice about getting a prescription from your doctor.

Melissa Block speaks with Eric Heginbotham — senior political scientist at RAND — about China's military capability today, how it's developed over time and what the Chinese make of ramped-up attention from the US.

The Egyptian government has further escalated tensions with Washington by accusing U.S. officials of directly funding nonprofit groups to create chaos in the Arab country.

The latest comments were made by an Egyptian Cabinet member to prosecutors conducting a criminal probe into the activities of 43 aid workers, many of them American.

Such claims anger U.S. officials, who have threatened to hold back more than $1 billion in military aid if the crackdown on private, pro-democracy organizations doesn't end.
