Toxins and pathogens be warned Imagine munching on a hamburger boldly knowing that it was not contaminated with E. coli or sipping a cold glass of water confident it was truly clean. Due to advances at Pacific Northwest National Laboratory, these ideas may become a reality. A team of PNNL researchers is developing a method to detect contaminants in food, water and air supplies.

Keeping the power on by linking the grid On the afternoon of August 14, 2003, an estimated 50 million people in the Northeastern and Midwestern United States and part of Canada suddenly lost electric power in a blackout that lasted up to four days in some areas. The massive outage represented 61,800 megawatts of lost power, cost the United States an estimated $10 billion, and drew attention to a critical need for improved power system reliability.

Detecting bioaerosols when time is of the essence About seven years ago, Livermore researchers received seed funding from the Laboratory Directed Research and Development Program to develop an instrument that counters bioterrorism by providing a rapid early warning system for pathogens, such as anthrax. Contact: Richard Langlois

Quenching marital bliss Niobium, mined in Brazil, needs to be exquisitely purified. It is one of 26 metals in the periodic table with natural superconducting properties. Contact: Interaction Point
15-Oct-2004
When it comes to accelerators, what is cold? Superconductivity arises in special materials at super cold temperatures. At these temperatures--a few degrees above absolute zero--the materials' electrical resistance virtually vanishes. Contact: Interaction Point

Researchers 'redesigning' platinum Researchers have developed a way of changing the properties of platinum by manipulating the metal at the nanoscale. The method mimics the action of photosynthetic proteins. Contact: Chris Burroughs
16-Sep-2004
Cold Molecules - New avenue to the 5th phase of matter Using a method usually more suitable to billiards than atomic physics, researchers from Sandia and Columbia University have created extremely cold molecules that could be used as an improved first step in creating molecular Bose-Einstein condensates (BECs). Contact: Neal Singer

Virtual problem solving for homeland security Probing attack on the water treatment plant! The mayor and other emergency responders evacuate schools, respond to medical emergencies, and pursue the perpetrators. Fortunately for the town of Opelika, Alabama, the attack was purely hypothetical. Contact: Rob Hills

Exploring the ultrawideband Lawrence Livermore research efforts and inventions quietly advance many fields. In one instance, however, a Livermore invention that stemmed from laser research has spawned a variety of new commercial products, including some that support national and homeland security. Contact: Steve Azevedo

Echoes of the past in silicon chips Thermal oxide is the real on-off switch for your computer. The nanometers-thick film on the surface of silicon transistors helps turn on and off the flow of electricity through the transistor, providing the 0 and 1 binary signals modern electronics run on. There are several million transistors on each computer chip. Contact: Interaction Point

Radiation detection on the front lines If you think a device that resembles a cellular phone but detects a potential nuclear threat and transmits a description of the nuclear material to every nearby crisis center sounds like something out of a James Bond movie, you are in for a surprise. Since the 1930s, when scientists first used the Geiger counter, radiation detection equipment has gone through an amazing evolution in size, sensitivity, deployability, and power.
