The Department of Homeland Security will begin releasing a dead bacteria into the Boston subway tomorrow in an operation it says will test sensors designed to detect biological agents that could be released as part of a terrorist attack.
Little is known about what exactly the bacteria consists of, and the DHS has not been very forthcoming with information, saying only that it is a “non-infectious” material that has been “approved as a food supplement”.
The tests will begin Wednesday and will be held periodically over the next year at the Harvard and Porter Square stations in Cambridge and the Davis Square station in Somerville.
“A rapid alert from a detection system can locate and identify these materials and provide for immediate and appropriate response to protect people and contain the hazard,” stated DHS scientist Anne Hultgren in the agency’s press release.
“This detection system will be one of the first such installed in the country, and, if it proves to be effective, could serve as a model for other mass transportation venues throughout the nation and the world,” said MBTA Transit Police Chief Paul MacMillan in the joint press release Monday.
Back in May when the plan was announced, Federal officials said that they were to release a bacteria called B-subtilis, noting that it “has been rigorously tested and has no adverse health effects for low exposure in healthy people.”
What effect the tests will have on unhealthy people or those exposed to higher doses is unknown.
The DHS has released a 28-page summary entitled ‘Environmental Assessment for Bacillus subtilis Particles to Challenge Bio-Detection Sensors in Subway Stations’ (PDF).
Given the federal government’s ominous record in releasing biological agents into subway systems and other transport hubs, it’s no surprise that this latest example is sure to cause consternation.
During a Senate hearing in 1977, it was revealed that the Pentagon had conducted numerous secret germ “attacks” on cities without public knowledge in an effort to test the threat posed by biological agents. These tests “may have caused outbreaks of disease which occurred in some of the test areas,” writes Leonard A. Cole, citing the Senate inquiry.
These “attacks” included a 1964-65 program carried out by the U.S. Army which involved unsuspecting travelers being sprayed with bacteria-laden mist at Washington’s National Airport.

DNA: Data-storage for eternity 2015-02-27 20:57
How can we preserve our knowledge today for the next millennia? ETH researchers have found a way to store information in the form of DNA, preserving it for nearly an eternity.
Scrolls thousands of years old provide us with a glimpse into long-forgotten cultures and the knowledge of our ancestors. In this digital era, in contrast, a large part of our ...
Hypercleanliness is making us sick - Children develop allergies and eczema 2015-02-27 20:31
Could using a dishwashing machine increase the chances your child will develop allergies? That's what some provocative new research suggests — but don't tear out your machine just yet.
The study involved 1,029 Swedish children (ages 7 or 8) and found that those whose parents said they mostly wash the family's dishes by hand were significantly less likely to develop eczema, ...
USDA: Can’t We Just Scan Food to See GMO Ingredients? 2015-02-27 20:26
Tom Vislack, secretary of the US Department of Agriculture (USDA) told Congress that labeling genetically modified foods (GMOs) could be unnecessary if customers “use their phones to scan special bar codes or other symbols on food packages in the grocery store” to determine the ingredients and identify GMOs.
Vislack said: “Industry could solve that issue in a heartbeat.”
This idea “could have ...
