Amidst concerns over violations of privacy, Homeland Security aims to operate 450 new body scanners at over 29 airports across the country this year. "The federal government is starting to deploy full-body scanning machines to 11 airports across the United States, Homeland Security Secretary Janet Napolitano announced Friday. Forty body-imaging machines already have been put into use at 19 airports nationwide as part of a field test, according the Department of Homeland Security. The Transportation Security Administration expects to deploy 450 units by the end of this year.
"By accelerating the deployment of this technology, we are enhancing our capability to detect and disrupt threats of terrorism across the nation," Napolitano said in a statement. The first of the new units are being installed Friday at Boston's Logan International Airport, according to a DHS statement. The imaging machines are being funded through the Obama administration's $862 billion economic stimulus plan.
Under existing protocols, full-body scans are optional at airport checkpoints. Travelers who decline the scans are funneled to a location where they may be given a pat down and subjected to other tests such as swabs that can detect minute traces of explosives on hands or luggage."

You can say 'no' to things, and you should. Do it like this.
- Give yourself permission to say "no" to things. Saying yes to everything is a fast way to burn out.
- Learn to say no in a way that keeps the door of opportunity open: No should never be a one-word answer. Say "No, but I could do this instead," or, "No, but let me connect you to someone who can help."
- If you really want to say yes but can't manage another commitment, try qualifiers like "yes, if," or "yes, after."
Three scientists publish a paper proving that Mercury, not Venus, is the closest planet to Earth.
- Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?
- Wrong! Neither Venus nor Mars is the right answer.

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
