A new device produced high-energy electron beams to break down harmful organic molecules and kill bacteria such as anthrax, providing a more affordable alternative to existing technology. The Coupled Multiplier Accelerator (CMA) has been licensed for commercial use to treat contaminated water and food.
A new method by USF researchers can detect anthrax spores in under 8 hours, reducing turnaround time from days. This breakthrough enables more laboratories to test samples, alleviating backlog and anxiety caused by long wait times.
Emory University is conducting a clinical trial to evaluate an improved anthrax vaccine regimen with reduced injections and muscle administration. The study will enroll 1,560 volunteers across six sites and aim to simplify the existing dosing schedule while providing more data on safety.
The model simulates the mail-borne anthrax outbreak in the US, demonstrating that six original letters contaminated up to 5,000 other pieces of mail, primarily affecting elderly recipients. The analysis highlights the greatest risk to society came from postal workers and recipients of cross-contaminated letters.
