A review of two aftermarket in car navigation systems (Sony’s Nav-U portable car GPS system and Verizon Wireless’ VZ Navigator phone service) from the Detroit Free Press begins this way:

Don’t want to rip into your dashboard to install a GPS system in your car, but want better directions than the printouts from a map Web site?

Is there any reason to believe these provide better directions than an online website? Granted, with GPS they can recalculate, but are the initial directions better? Is the data more up-to-date? The algorithms different? I just found that a bold statement.

“As maps they would still work. I imagine that’s what most people do with them.”

Andrew Weir, vice-president of Tourism Toronto when made aware that two year old maps were being given out by a city-run tourist booth. Advertisements for shows and their prices were noted as out of date. The old maps have since been destroyed.

A PhD candidate at Australian National University using unclassified CORONA satellite images has found evidence of ancient human settlement in Syria.

Ms Mottram’s team aims to establish for the first time a record of human occupation in the area, from the first arrival of early human groups between 1 million and 700,000 years ago, to Ottoman times.

The CORONA program ran in the 1960s and the images were declassified in the 1990s. Recall that Corona films (yes, actual films) were dropped from the satellites to be caught by aircraft. Those that fell into the sea were designed to disintegrate in the salt water. (This was some of the coolest technology I read about in researching remote sensing!)

“Average folks are finding really surprising things on Google Earth because it’s accessible to the average Web surfer. It’s closer to curiosity than military advantage.”

Noah Shachtman, editor of Defense Tech, on the recently found Chinese model of the disputed border territory with India.

Not exactly, but a study suggest that different skin cells in the body “know where they are” based on cues in genes. So feet and leg cells are different than scalp and hand cells. This from a Stanford University study reported in Medical Research News.

Says John Rinn, PhD first author of the study published in the current issue of Public Library of Science-Genetics,  “Our skin is actively maintaining itself throughout our life, and these ‘address codes’ help the cells know how to respond appropriately.”

The analogy to GPS is a strech for me, but it certainly caught my attention.
