North Carolina prepares for bioterrorism, epidemics
North Carolina universities and state and federal agencies create the new North Carolina Bio-Preparedness Collaborative; the idea is to use computers to link all the disparate forms of data collected by various agencies quickly to root out indicators of new disease, or food-borne illness, or, in a worst-case scenario, an attack of bio-terrorism

The optimal balance of vaccine stockpiles
Once a disease has been eradicated there is a danger it could reappear, either naturally or as a result of an intentional release by a terrorist group; how much vaccine should be produced and stored for a disease that may never appear again — or which may infect hundreds of thousands tomorrow? modelers target optimal vaccine storage for eradicated diseases

A first: plastic antibodies pass initial test
Plastic antibodies, which mimic the proteins produced by the body’s immune system, were found to work in the bloodstream of a living animal; the discovery is an advance toward medical use of plastic particles custom tailored to fight an array of antigens

Researchers develop an Ebola vaccine
Researchers develop an experimental vaccine that cures the Ebola virus by targeting its genetic material; trouble is, the Ebola vaccine can only work if it is administered within thirty minutes, which is an impracticality among civilian populations; the vaccine is a viable possibility within a research facility, so it may be used to protect the researchers themselves

Coral snake antivenin to run out in October
If you live in Florida, you should now be doubly careful not to be bitten by the poisonous coral snake; the only company making antivenin for coral snake bites is no longer producing the drug — and the last batch will hit its expiration date in October.

Defeating anthrax bacterium's natural defenses may hold key to new treatments
Up to 90 percent of untreated cases of inhalational anthrax result in death; Bacillus anthracis, the causative agent of anthrax, is particularly lethal because of its protective coating, or capsule, which enables the pathogen to escape destruction by the host’s immune system; researchers discover a way to “trick” the bacterium into shedding its protective covering

Utah implements harsh triage guidelines for bioterror, epidemic emergencies
Utah’s new triage health emergency guidelines would see some children and some seniors turned away from hospitals during a bioterror or epidemic emergency; those who are severely burned, have incurable and spreading cancer, fatal genetic diseases, end-stage multiple sclerosis, or severe dementia will be turned away; people older than 85 also would not be admitted in the worst pandemic; those who have signed “do not resuscitate” orders could be denied a bed

Is there a connection between ending smallpox vaccination and the explosive spread of HIV?
Smallpox immunization was gradually withdrawn from the 1950s to the 1970s following the worldwide eradication of the disease, and HIV has been spreading exponentially since approximately the same time; researchers show that vaccinia immunization, given to prevent the spread of smallpox, produces a five-fold reduction in HIV replication in the laboratory; is there a connection between the end of smallpox immunization and the spread of HIV?

Ricin: the most potent -- and readily available -- bioterrorism weapon
Ricin is of particular concern when it comes to bioterror agents: ricin is not only deadly, but it is also easy to obtain; it is a natural ingredient in the seeds of castor oil plants, which are used in the industrial production of brake fluid, varnish, soap, ink and other products; researchers offer ways to protect human cells from ricin

Synthesized polymer neutralizes both biological and chemical weapons
Biological tissues to respond rapidly and appropriately to changing environments; this logic was applied by University of Pittsburgh researchers: they have synthesized a single, multifunctional polymer material that can decontaminate both biological and chemical toxins

Korean scientists develop fast, accurate pathogen detection sensor
On average 540 million people become sick with harmful bacteria every year with fifteen million losing their lives to infectious disease around the world; the key to fighting infectious disease is for doctors to determine quickly what kind of pathogen or infectious agents have entered the body and sidestepped the natural immune system

Beating mosquitoes at their own game
Japanese researchers came up with a brilliant idea: why not use mosquitoes as “flying vaccinators” or “flying syringes”? Normally, when mosquitoes bite, they inject a tiny drop of saliva that prevents the host’s blood from clotting; the Japanese group decided to add an antigen — a compound that triggers an immune response — to the mix of proteins in the insect’s saliva; it worked

Nuclear Medical Center established for early detection of injuries
The Israeli military uses a new technology which allows early detection of injuries sustained by soldiers better than any other diagnostic tests; the system uses a new nuclear medicine system, which includes a new nuclear camera; the new camera has a sensitivity of 100 percent for diagnosing stress fractures, enabling the diagnosis of an injury already at the stage of a minor fracture and prevents it from worsening

How best to protect first responders from anthrax
The first responders who rushed to Senator Tom Daschle’s office on 15 October 2001 were protected by personal protective equipment (PPE); yet, nasal swabs taken from them after they got out of the building revealed that some had been exposed to anthrax; experts argue that first responders and emergency personnel should all be vaccinated
