The Centers for Disease Control and Prevention (CDC) released a report on July 11 that reviews the early June incident that involved the unintentional exposure of personnel to potentially viable anthrax at the CDC’s Roybal Campus. The report identifies factors found to have contributed to the incident; and highlights actions taken by the agency to address these factors and prevent future incidents. Based on a review of all aspects of the June incident, CDC concluded that while it is not impossible that staff members were exposed to viable B. anthracis, it is extremely unlikely that this occurred. None of the staff who was potentially exposed has become ill with anthrax.

Research associated with the development of new agricultural pesticide formulations centers around the design of products that provide highly effective and specific action towards the target organism with reduced application rates. It is estimated that 30% of the pesticides on the market today have optical isomers. However, the desired activities often result from one single enantiomer in the optical isomer mixtures.

Using spider toxins to study the proteins that let nerve cells send out electrical signals, Johns Hopkins researchers say they have stumbled upon a biological tactic that may offer a new way to protect crops from insect plagues in a safe and environmentally responsible way.

Some viruses can hide in our bodies for decades and make ‘fake’ human proteins that trick our immune cells into believing nothing is wrong. Now researchers at the Imaging Centre of Excellence at Monash and Melbourne Universities have determined the basic structure of one of the two known families of these deceptive proteins.
