When President Obama came into office, he promised to close the prison at Guantanamo Bay, Cuba, for good. In the years since, lawmakers on both sides of the aisle have made that difficult. Congress has barred the transfer of Guantanamo detainees to the continental U.S. and has made it difficult to send the suspected terrorists to third countries. That may be why the prison is beginning to feel permanent.

In the crowded race for the 2012 Republican presidential nomination, Mitt Romney may be the tortoise, but Newt Gingrich is the newt. And newts are highly adaptive salamanders that regenerate limbs when wounded and emit poison when challenged.

Conventional — and up-to-the-minute contemporary — wisdom pegs Gingrich as the ascendant favorite, knocking other candidates off their posts and platforms like an Angry Bird.

The congressional supercommittee has only a few days left to come up with a plan to cut $1.2 trillion from the federal deficit. One of the areas on the chopping block is the nation's defense budget, and Pentagon officials are pushing back against any cuts beyond the $450 billion they've already been asked to make.

The defense budget is an easy target when it comes to cutting the deficit, because it makes up half of the federal government's entire discretionary budget, says Todd Harrison, a senior fellow at the Center for Strategic and Budgetary Assessments.

Should the United States give aid to China? Given America's trade imbalance with China, few politicians think it's a good idea.

That's why a hearing over $4 million that the U.S. Agency for International Development intends to spend on environmental programs in China drew such heat on Capitol Hill this week.

A bipartisan group of lawmakers lined up at a House hearing on Tuesday to denounce the program as "an insult to the American taxpayer" that would pour "U.S. taxpayer dollars down the toilet."

We were stunned when we saw this image:

According to HRL Laboratories that is an "ultralight metallic microlattice" sitting atop a dandelion. The material was developed by scientists at HRL, The California Institute of Technology and the University of California, Irvine.

The material is 99.99 percent air and 100 times lighter than styrofoam.

There's no Peggy Sue — or even a Margaret or a Susan, for that matter — in the British folk-rock band Peggy Sue. There is, however, a hard-driving group that has just released its second album, Acrobats. Peggy Sue is the trio of singers and guitarists Rosa Slade and Katy Young, and drummer Olly Joyce.

The self-help guru responsible for three deaths at a 2009 sweat lodge ceremony in the Arizona desert was sentenced to two years in prison, today.

At his sentencing James Arthur Ray begged for forgiveness. The AP reports:

"Ray said during his sentencing hearing that he would have stopped the ceremony near Sedona had he known people were dying or in distress. He turned to the more than a dozen family members seated in the courtroom, tearfully taking full responsibility for the pain and anguish he caused them.

Republican Newt Gingrich's presidential stock is rising in the polls. And his newfound popularity is also bringing new scrutiny to what he's been up to since he stepped down as Speaker of the House in 1998.

Joe Paterno's son said his father has lung cancer, but that it was treatable.

The AP reports:

Scott Paterno says in a statement provided to The Associated Press by a family representative that the 84-year-old Joe Paterno is undergoing treatment and that "his doctors are optimistic he will make a full recovery."

Saying it is deeply troubled by "tragic events" alleged to have happened at Penn State, the NCAA has told the school it is launching an examination of whether the university has "institutional control over its intercollegiate athletics program, as well as the actions, and inactions, of relevant ... personnel."

It's hard to miss the irony: Leon Panetta, as President Clinton's budget guru, backed billions of dollars in Pentagon cuts. Now, as secretary of defense, he's warning that the U.S. could become a "paper tiger" if his department's budget is further reduced.

The artist Ai Weiwei can't seem to catch a break with the Chinese government. His open dissension, of course, doesn't help, but the government has kept coming after him time and time again.

Melissa Block talks with John Seabrook, staff writer at The New Yorker. His latest article, "Crunch," delves into the world of the SweeTango — a new hybrid apple that is part Honeycrisp, part Zestar. It's sweet and tangy. There's a hint of cinnamon, a hint of pineapple and a whole lot of crunch.

On Thursday, the U.S. military successfully tested a new hypersonic missile. The missile flies at eight times the speed of sound with a range measured in the thousands of miles. That allows the missile to hit a target anywhere on earth in less than an hour. Guy Raz talks with Noah Shachtman of Wired.com about how the Army's Advanced Hypersonic Missile works.
