When the DNA portion of the nanosensor binds to a target molecule, there will be a slight change in the electric charge near the nanotube, ... The nanotube will then pick up on that change, turning it into an electric signal that can then be reported.

What we have here is a hybrid of two molecules that are extremely sensitive to outside signals: single stranded DNA, which serves as the 'detector,' and a carbon nanotube, which functions as 'transmitter,' ... Put the two together and they become an extremely versatile type of sensor, capable of finding tiny amounts of a specific molecule.

You and I share the same DNA.
Is there anything more lonely than that?

[Katrina, however, knocked out a substantial portion of the nation's petroleum infrastructure, especially refineries that produce gasoline, when gas supplies were already stretched thin.] The larger worry may not be Katrina itself, ... but if energy prices were to continue their sharp climb.

There were 39 fatalities in 2005, which was a slight reduction from the 41 fatalities that occurred in 2004 and a 40 percent reduction from 1998's 65 fatalities.

We actually probably should have moved him down a year earlier because when we played really good teams, people were killing us at left tackle.
