John David Snell inspects stagnant water at a foreclosed Key West home for signs of Aedes aegypti mosquito larvae. The mosquitoes, which transmit the dengue virus, have become more prevalent in the U.S.
Tropical diseases like dengue fever sound as if they belong in faraway places. But in the past several years, some have begun showing up in the continental U.S.
Now in Key West, Fla., public health officials are combating a scourge they thought they'd eradicated seven decades ago.
Dengue Back After Long Absence
Until recently, a locally contracted case of dengue fever had not been seen in Florida since 1934. That suddenly changed in 2009, when doctors in Key West began seeing it in people who had not traveled outside the area.
One of the rumored names for element 114 is Flerovium, after Soviet scientist Georgy Flyorov.
Two new elements were officially added to the periodic table this month. The elements were discovered years ago, but they needed approval from an international committee before they could be placed on the famous chart. We asked Ian Chillag and Mike Danforth, producers of NPR's Wait Wait, Don't Tell Me and hosts of the podcast How To Do Everything, to explore how the process works:
Pakistani sailors parade during a rehearsal for a National Day ceremony in Islamabad in 2005. Before a militant raid on a naval base in Karachi last month, a number of navy personnel were detained on suspicion of links to al-Qaida, security officials say.
Have al-Qaida and other militant groups wormed into Pakistan's military?
It's an explosive question, considering that Pakistan's armed forces are vital U.S. allies and also guardians of a stockpile of nuclear weapons. And that was the question a Pakistani journalist addressed in an article written shortly before he was murdered last week.
Saleem Shahzad reported on last month's militant attack on a Pakistani naval base in Karachi. He quoted anonymous sources who linked that attack to the discovery of suspected al-Qaida operatives inside the navy itself.
