Europeans install radiation detectors as U.S. question detectors' efficacy
U.S. legislators raise questions about DHS’s $1.4 billion program which aims to deploy nuclear radiation detectors in U.S. ports; GAO raises questions about test methodology of latest technology; Europeans, though forge ahead with port deployment

Living cells as bioterror detectors
Terrapin researcher has an idea for bioterror attack detection: Use cells that die when exposed to a particular pathogen, thus providing the early warning; the cells are also engineered to produce a signal, such as fluorescence, when attacked

Laser diodes with world's shortest wavelength for bioterror detection
Currently, the shortest laser diode reported measures 343nm — which is problematic: Most biological molecules show strong absorption in the ultraviolet spectral region ranging from 280nm to 340nm; researchers at Bristol and Sheffield universities fabricate the first 337nm laser diode — allowing for continuous monitoring of biological molecules; technology will also increase capacity for information storage

Hygiena launches hand-held device for contaminant detection
A New Jersey food processor just went belly up as a result of having to launch the second largest recall of contaminated beef in U.S. history; a California company says that if its hand-held contamination monitor were used, the contaminant would have been found earlier, reducing the size of the recall and the subsequent financial hit

Uncertainties about nuclear waste storage
The waste created in the production of U.S. nuclear weapons is buried in Hanford, Washington; there is a growing uncertainty about the subsurface paths nuclear contaminants take, where they travel, and how fast

DHS's ambitious nuclear radiation detection plan has its critics
DHS envisions a protective radiation system which will ring the United States with radiation monitors at ports, along isolated sea coasts, traveling the oceans, roaming highways in police cars, and even located at checkpoints and toll booths on routes into major cities — all connected to a central national command center and staffed around the clock; critics have their questions

Border Web cameras along Texas-Mexico border go online again
Texas governor Rick Perry found the funds to have virtual watch up and running — again — as early as January; Texans can register to have 200 border cameras feed images to their home PCs; if they see people crossing the border, the can call or e-mail authorities

The long view
Keeping the Lights on with Nuclear Waste: Radiochemistry Transforms Nuclear Waste into Strategic Materials
How UNLV radiochemistry is pioneering the future of energy in the Southwest by salvaging strategic materials from nuclear dumps –and making it safe.
Model Predicts Long-Term Effects of Nuclear Waste on Underground Disposal Systems
The simulations matched results from an underground lab experiment in Switzerland, suggesting modeling could be used to validate the safety of nuclear disposal sites.
