Hydrogen bombs, like the one North Korea detonated in January, have thankfully never been used in war. These bombs, also called H-bombs, rely on the fusion of hydrogen atoms, and can be thousands of times more powerful than nuclear bombs. They are easily weaponized in small packages and are capable of devastating a large city in one detonation.
North Korea has plans to further demonstrate their technical capabilities by shooting one or more missiles over the Japanese homeland. The Japanese are understandably rattled, and this past Wednesday Japan vowed to shoot down any North Korean missiles fired over its territory.
We may not be as nervous about nuclear war as those who practiced 1960s "duck and cover" drills, but there are other threats to peace that create regular alarm. At this moment there are 10 active wars worldwide. more >>
President Barack Obama claimed in a wide-ranging interview that he has met most hopes and expectations people had of his presidency, and also singled out Pope Francis' visit to the White House as a stand-out moment.
"I've done a lot of them and I've made progress on almost all of them," Obama told "CBS This Morning" about voters' expectations in an interview that was posted on Tuesday.
"I feel pretty good about being able to match up what I said I would accomplish with what has been accomplished. I mentioned in the State of the Union that one of the things I regret though is that I haven't been able to drain some of the rancor that exists here in Washington," he continued. more >>

What is the final frontier? Whenever I ask my Earth Science 101 students they answer that the final frontier is space. This is no doubt because they have been acculturated by the ubiquity and glamour of space exploration in the popular imagination.
The Apollo program conceived in early 1960 during the Eisenhower administration ignited the dreams of a generation that lacked the drama of exploration that characterized their recent ancestors. Apollo missions merged seamlessly with the popular television series Star Trek, which began in 1966.
Captain James T. Kirk, the boyish and impulsive hero, augmented the romance of space travel with his promise to explore "brave new worlds." That his middle name is Tiberius — perhaps after one of Rome's greatest generals, who became a moody and reluctant Emperor — only added to the gravitas. more >>
If you worry about climate change, here's something that ought to grab your attention.
One of the newest and most-rapidly spreading memes in popular science is what's being dubbed the "Anthropocene." According to this meme, human beings are having such an impact on the environment, especially the climate, that we've entered a new geological age.
That's exactly the point a recent article that British geologist Colin Waters and his colleagues recently made in the journal Science. They argue that the combination of the "rapid global spread of novel materials including aluminum, concrete and plastics" and "fossil-fuel combustion," and the "atmospheric testing of nuclear weapons" has produced "rapid environmental change" sufficient to call our times a new geological age. more >>
