...certain that Asian carp have made it into the Great Lakes. The Mississippi River system and the Great Lakes are connected only through the man-made Chicago Sanitary and Ship Canal, which leads from Lake Michigan to the Illinois River. (It's not uncommon for invasions to occur when humans connect ecosystems that have naturally been kept separate.) The Army Corps of Engineers put an electric barrier in the canal to prevent the carp from infiltrating Lake Michigan, but it may not have been enough - although no live fish have been found yet, last month a team of scientists discovered...

That said, we do not wish to pass judgment on how and where soldiers should reveal their sexual orientation, if they choose to at all; we merely maintain that the military’s emphasis on such a broad integration should occur in an environment that is less emotionally taxing than combat...
...When you consider we transport 1.2 million people a day on our system, the number of crimes that occur on our system is incredibly low,” said Joseph O’Connor, deputy chief of the MBTA Transit Police...
...completed specific mental tasks. But more recently, thanks in large part to the proliferation of functional magnetic resonance imaging (fMRI), which precisely maps brain activity based on changes in blood-oxygen levels, neuroscientists have found that important activity in the brain - related in particular to memory and learning - may occur when it is at rest...
...human brain, although encased by a heavy-duty cranium, isn't designed for football. Helmets do a nice job of protecting the exterior of the head and preventing deadly skull fractures. But concussions occur within the cranium, when the brain bangs against the skull. When helmets clash, the head decelerates instantly, yet the brain can lurch forward, like a driver who jams the brakes on. The bruising and stretching of tissue can result in something as minimal as "seeing stars" and a momentary separation from consciousness...
