After September 11 when terrorists attacked America, anthrax letters were mailed out in the US on September 18 just seven days after the Twin Towers of the World Trade Center fell.
I know I was a little edgy at the time wondering where all this craziness in America was heading. People were dying from white powder in their mailbox and buildings were being evacuated to be decontaminated.
Sept. 11, 2001: Terrorists hijack four airline jets and crash them into the World Trade Center towers in New York City, the Pentagon in Virginia and a field in rural Somerset County, Pa.
Sept. 18, 2001: The first letters containing the bacterium are mailed.
Oct. 4, 2001: Bob Stevens of American Media in Florida is hospitalized with inhalation anthrax.
Oct. 5, 2001: Stevens, 63, dies. It's the first Bacillus anthracis death in the U.S. in 25 years.
Oct. 8, 2001: It is found in the Boca Raton, Fla., offices of American Media, publisher of the National Enquirer. The building is closed.
Oct. 9, 2001: More letters laced with are posted, and the FBI begins investigating the incidents.
Oct. 12, 2001: An NBC employee in New York City tests positive for poisoning.
Oct. 15, 2001: Senate Majority Leader Tom Daschle (D-SD) tells reporters bacterium Bacillus anthracis was found in his office.
Oct. 16, 2001: The 7-month-old son of an ABC News freelance producer tests positive for bacterial poisoning. The baby developed a rash soon after visiting the network's Manhattan offices on Sept. 28.
Oct. 18, 2001: A CBS employee and a New Jersey postal worker test positive for poisoning.
In 2002 while working on a technology to grow plants in space NASA discovered a way to kill the bacterium with titanium dioxide. "Space-based greenhouses may seem to have little to do with the war
against terrorism," said Mark Nall, director of the Space Product
Development Program at NASA's Marshall Space Flight Center in
Huntsville, Ala. "Yet this invention shows how commercial space research
can benefit Earth in many ways.

is a tabletop-size
metal box that bolts to office ceilings or walls. Its fans draw in
airborne spores and airflow forces them through a maze of tubes. Inside,
hydroxyl radicals (OH-) attack and kill pathogens. Most remaining
spores are destroyed by high-energy ultraviolet photons.Basically the TiO2 pops off the hydrogen peroxide and this nicks away at the cell wall therefore killing the bacterium. Go to NASA site here
