Scientists have discovered a pocket of ancient seawater that's been trapped underground near the mouth of the Chesapeake Bay since the time of the dinosaurs — strong evidence that the Atlantic Ocean was once much saltier than today.

It's the question beyond all questions, the central enigma, the unrelenting mystery. Beyond understanding the nature of matter or the origin of species, past the strangeness of quantum computing or the reality of a multiverse, it's there. Always.
Okay. We all know about the partisan divide in this country - Democrats, Republicans - but there's another political divide. Part of the country is very engaged in the political process and part is not.
RENEE MONTAGNE, HOST:
Older Americans, richer Americans and better educated Americans are more likely to be politically engaged. Now researchers have found one more factor that seems to shape political engagement, the length of your commute. It comes to our attention as MORNING EDITION focuses on commuting.
The physical damage from Typhoon Haiyan in the Philippines is catastrophic. Hundreds of thousands of people are now homeless.
Soon, though, people will start to rebuild, as they have after similar natural disasters.
How they do it, and where, is increasingly important in places like the Philippines. The island nation lies in a sort of "typhoon alley," and with climate change and rising sea levels, there are more storms in store.
Workers at Japan's Fukushima Dai-Ichi nuclear power station successfully completed the first day of a delicate operation to remove radioactive fuel rods from a reactor damaged in the March 2011 tsunami.
The fuel rods were removed from the Unit 4 reactor, which was offline at the time the tsunami smashed into the plant, overwhelming its backup systems. Although Unit 4 was spared the fate of three other reactors that melted down, a fire in its containment building weakened the structure.
NASA's MAVEN explorer blasted off Monday on the first leg of its 440-million-mile journey to Mars, where scientists hope it will answer an ancient question: why the red planet went from warm and wet to cold and dry in a matter of just a billion years.
The robot orbiter, called the Mars Atmosphere and Volatile Evolution probe, launched aboard an Atlas V rocket from Cape Canaveral Air Force Station at 1:28 p.m. EST. It will take 10 months to reach Mars.
There's something deeply compelling about "seeing" the mind at work with the help of relatively new neuroscientific tools, such as functional Magnetic Resonance Imaging (fMRI), which furnish the images of brain activation that often accompany popular science coverage. Indeed, a well-known 2008 paper by McCabe and Castel reported that people thought articles containing fMRI images of the brain reflected better scientific reasoning than matched articles that did not.
