Researchers develop new tool to detect agents of bioterrorism

06.01.2005


Scientists have developed a new "biological smoke detector" to help protect against potential bioterrorist attacks, according to a study published in the Jan. 1 edition of Analytical Chemistry, a peer-reviewed journal of the American Chemical Society, the world’s largest scientific society.



High-traffic facilities like airports, office buildings, rail stations and sporting arenas serve hundreds of thousands of people each day, making them particularly susceptible to silent and invisible biological attacks. Researchers from Lawrence Livermore National Laboratory in California have now developed a new stand-alone detector that can provide early warning to help authorities limit exposure and start treating victims before they show symptoms of full-blown infection.

The instrument, called the Autonomous Pathogen Detection System, or APDS, continuously monitors the air like a "biological smoke detector," says John Dzenitis, Ph.D., a chemical engineer at LLNL and corresponding author of the paper. It is capable of detecting and identifying three types of biological agents: bacteria, viruses and toxins, including such familiar threats as anthrax, plague and botulinum toxin. The machine runs the same tests that molecular biologists would carry out in a laboratory to detect biological agents, providing information that is required before definitive public-health action can be taken.


LLNL has been working on this instrument since 1995, but this new version, tested at the U.S. Army’s Dugway Proving Grounds in Utah, is a step-change in capability, Dzenitis says. Now, in addition to simultaneously testing for multiple agents with protein antibodies, the APDS also confirms positive results with a DNA test specific for the agent. No other field system has two independent molecular biology tests. Having two laboratory-quality tests further reduces the probability of a false alarm and gives confidence for effective response.

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
