"As an antiterror measure, the U.S. government has deployed mobile X-ray technology to randomly scan cars and trucks. But the measure is riling privacy proponents."
"For many living in a terror-spooked country, it might seem like a great government innovation: Use vans equipped with mobile X-ray units to scan vehicles at major sporting events, or even randomly, for bombs or contraband.

'This really trips up the creep factor because it's one of those things that you sort of intrinsically think the government shouldn't be doing,' says Vermont-based privacy expert Frederick Lane, author of 'American Privacy.'"
Scientists have developed new ways of understanding how the biological forces of death drive important life processes.
- Researchers have found new ways on how decomposing plants and animals contribute to the life cycle.
- After a freak mass herd death of 300 reindeer, scientists were able to study a wide range of the decomposition processes.
- Promoting the necrobiome research will open up new areas of inquiry and even commerce.
What do we see from watching birds move across the country?
- A total of eight billion birds migrate across the U.S. in the fall.
