Researchers from Canada and the United States have developed a drug that could someday be used to treat people exposed to anthrax bacteria specifically engineered to overcome antibiotics.

U.S. officials say they have fresh concerns about the nation's vulnerability to terrorist attacks because they now recognize that anthrax spores could be more widely dispersed than previously believed.

Experts have said that the Bush administration?s plans for increased biological defense research could take away necessary funding from other medical research projects.

An anthrax weapon aimed at a major city could kill at least 123,000 people even if every victim received treatment, experts have calculated.

U.S. scientists have made a breakthrough which they believe could thwart one of the most nightmarish forms of terrorism -- an attack with antibiotic-resistant biological weapons.

The authors propose that anthrax attacks could be detected in advance by analyzing grocery data for higher than normal incidences of consumers buying over-the-counter medication.

Scientists using the power of more than a million home computers, all linked together and cranking along as one, say they have come up with thousands of possible compounds that could be developed as a cure for anthrax.

A multiple-sponsor distributed computing project aims to derail anthrax's ability to enter human cells and eliminate the toxin as a terrorists' weapon.

A coalition of scientists and technology companies is asking people around the world to use their computers' extra processing power to help search for a cure for anthrax.

For nearly a decade, U.S. Army scientists at Dugway Proving Ground in Utah have made small quantities of weapons-grade anthrax that is virtually identical to the powdery spores used in the mail attacks that have killed five people, government sources say.
