Mail-based bioterror attacks made headlines last week when traces of ricin, a poison derived from the castor bean and a common by-product of castor oil, was found in letters addressed to President Barack Obama, Mississippi Republican Sen. Roger Wicker and Lee County, Miss., Justice Court Judge Sadie Holland, according to reports from the Associated Press.
Tiny versions of the reflectors on sneakers and bicycle fenders that help ensure the safety of runners and bikers at night are moving toward another role in detecting bioterrorism threats and diagnosing everyday infectious diseases, scientists said.
Researchers at Sandia National Laboratories are developing a medical instrument that will be able to quickly detect a suite of biothreat agents, including anthrax, ricin, botulinum, shiga and SEB toxin.
Don't look for testing of the anthrax vaccine to begin in children any time soon. Controversy arose last year as experts debated whether such studies should be done to learn how to treat children in case of a bioterror attack.
In an advance toward closing a major gap in defenses against terrorist attacks and other mass casualty events, scientists are reporting discovery of a promising substance that could be the basis for development of a better antidote for cyanide poisoning.

With the emergence of RNA interference (RNAi) as a powerful analytical tool in mammalian genetic screening, the RNA research field has seen a marked resurgence in its vitality.
PowerMax Soil DNA kit isolates DNA from up to 10 g of almost any soil type. The DNA yields are high and clean, and total DNA is free from inhibitors that could affect RT PCR. Each ready-to-use kit includes all required reagents.

By Aaron Sender Researchers at Rockefeller University, New York, have determined the structure of a potent DNA-damaging protein involved in many bacterial diseases.
by Elizabeth Tolchin A group of chemists at Northwestern University, Chicago, claim they developed a diagnostic method that is much faster, easier to use, more accurate, and less expensive than polymerase chain reaction (PCR).
Over 350 products are featured in this catalog, with special sections outlining antibodies to bioterrorism agents, food and waterborne pathogens, and toxins.
by Dan Stevens, Ph.D. By the early '90s, molecular biology techniques such as DNA sequencing and high-throughput screening had become well established in life sciences laboratories, and researchers were beginning to use them as sources of reliable data.
