Boston (CNN) - Two friends of Boston Marathon bombing suspect Dzhokhar Tsarnaev pleaded not guilty Tuesday in federal court to charges of conspiracy to obstruct justice and obstructing justice with intent to impede authorities.
Handcuffed and dressed in orange jail jumpsuits, Dias Kadyrbayev and Azamat Tazhayakov both voiced their not guilty pleas on each of the counts during their roughly four-minute arraignment Tuesday in Boston. They remained in handcuffs afterward, when they were led out of court.
An Air Force nuclear missile unit failed a safety and security inspection this week, the second wing of its kind to stumble on tests this year.
The latest involves the 341st Missile Wing at Malmstrom Air Force Base in Montana, which operates about a third of the 450 Minuteman III nuclear-tipped intercontinental ballistic missiles, according to an Air Force statement.
The wing received an "unsatisfactory rating" after making "tactical level errors" during one of several exercises conducted as part of the inspection.
A review is underway to determine accountability.
Washington, D.C., ain't cheap, especially when you are an unpaid intern on the hill. But one enterprising young woman is crowdsourcing her way to the Capitol.
When Jessica Padron was offered an unpaid internship with Senate Majority Leader Harry Reid that she could not afford, she did not go to a bank to get the cash she needed to make ends meet, she went instead to the internet.
So far Padron has raised about half of her goal, roughly $6,400, to survive four months in Washington D.C.
CNN's Erin McPike reports.
Want to know if Hillary Clinton is really running for president in 2016? Just ask New York City mayoral candidate Anthony Weiner. He fielded a question about his wife, a close aid to the former Secretary of State on Monday.
"Do you know what her role in Hillary's 2016 campaign is going to be?" Buzz Feed's Ben Smith asked Weiner.
"I do," Weiner replied.
"And what will it be?" pressed Smith.
"I'm not telling you," said Weiner.
That would kind of suggest that she's running.
CNN contributor and Democratic strategist Donna Brazile said the Clintons' annoyance with Weiner is probably "off the charts" right now.
"Anthony Weiner will likely soon be history. Given the recent revelations, I don't think anybody is going to take him seriously," said Brazile. "He's now running against the establishment. But voters have some excellent choices up there. I'm sure they will pick a winner and it will not be Anthony Weiner."
Exo-skeletons are found found in nature, such as those that protect cockroaches. Remember what they say about how they can withstand nuclear explosions?
But there's a spate of exoskeletons to be found on the silver screen. In the box office smash "Elysium," the difference between Matt Damon's character being able to save the world and fail is an exo-skeleton, and technology that turns a metallic frame into a wearable boost beyond human capability.
Matt Damon is just the latest star to try on a super suit. "Iron Man" and Nintendo's "Metroid" have one, actress Sigourney Weaver stomped around in one for "Alien," and "Starship Troopers" paved the way for them all.
With a robust history of pop culture examples, its no wonder that real-life prototypes have also been evolving for decades.
