But the federal government didn't laugh. Now, armed with a half million-dollar grant from the Pentagon, the Colorado State University plant biologist is trying to genetically engineer Arabidopsis plants to change color rapidly if they sense a biological or chemical agent. If her plan works, the technology could be used to turn forest evergreens, backyard shrubs or even pond algae into sentinels for scientists. One day, everyone in America might be able to use a cheap houseplant as an early-warning system. It could be the proverbial canary in a coal mine for the post-Sept.11 age. " A lot of us started thinking differently after 9/11, " Medford says. When she ran the idea by government officials, " they said, 'Well, let's give it a try, because if it does work, it could make a huge difference.' " Medford's Fort Collins, Colo., laboratory is among scores across the country where scientists and entrepreneurs are working on products that could help the government prevent or respond to another terrorist attack. In Richmond, Va., a biologist is trapping insects such as beetles, crickets, bees and moths to see whether they could be used as environmental monitors of biological and chemical agents. In Menlo Park, Calif., researchers are trying to develop a handheld voice-recognition translator that could help federal border agents communicate with foreigners seeking to enter the United States. Outside Chicago, workers at a small research company are seeking to devise an inexpensive DNA detector that could be used by people with no background in molecular biology to diagnose, quickly and accurately, an infectious disease such as smallpox. These efforts sound like they belong in a science-fiction movie. But they're all real-life, cutting-edge projects, funded partially by government grants. Officials acknowledge that some of the projects won't pan out. But they say government investment in high-tech research is worthwhile. Some of the projects could be useful additions to the war on terrorism; others could revolutionize the way officials protect the nation from attack. (Related video: New weapons in war against terror) Most of the projects now are funded through the Defense Department. But after tightening security at the nation's borders and airports, the Department of Homeland Security is getting involved. The department has $130 million this year to spend on projects it deems worthy. " We aim to attract the very best minds from the private sector and the academic community and get them working on high-stakes, high-payoff projects, " Homeland Security Secretary Tom Ridge said in a recent speech marking the department's 100-day anniversary. Anti-terror weeds and bugs Under the terms of Medford's grant, she has 18 months to figure out how to make her weeds tattle on terrorists. If one of her plants noticed a deadly nerve agent such as sarin gas, it would probably be too late to help people nearby. But if it sensed anthrax in the air, people could know they were exposed before showing symptoms. That would give them more time to take antibiotics. Medford's not using real biological and chemical agents in her experiments, which are aimed at causing the rapid breakdown of chlorophyll. She's using estrogen, because experiments have found it will prompt the " de-greening circuit " in plants. That has prompted jokes from friends who tell her, " Estrogen could be a terrorist agent. " Other cutting-edge projects under way: .. At Virginia Commonwealth University in Richmond, biologist Karen Kester has worked for two years to see whether insects can deliver information about hazardous or deadly agents in the soil, on the ground or in the air. Funded by a $1 million Pentagon grant, she uses black lights, sticky papers and traps to collect more than two dozen species of bugs. The bugs are " like little sponges or dust mops, " Kester says. If officials suspected a toxin had been released in a building or a park, they could mobilize teams of emergency workers in protective suits to swab for samples. Or they could let the bugs crawl and fly around, picking up samples, and then collect them for tests. For routine monitoring, she says, bugs could be used as part of a " 24/7 sampling scheme. " .. In Menlo Park, Calif., speech-technology researchers at SRI International have their hearts set on a small, handheld computer that can act as an instant translator. The device would be able to understand almost anything and immediately translate it into another language. Now a prototype, it could be used by soldiers, border agents and airport security workers as " a tiny computer mediating communication between two human beings, " says SRI's program director, Kristin Precoda. .. In Northbrook, Ill., a company called Nanosphere wants to invent an inexpensive device that would recognize the DNA from any infectious disease and diagnose it. If it works, emergency workers, doctors and hospitals could figure out fast whether a person, or a water or food supply, had been infected with a deadly or contagious biological agent. Today, in terms of bio-detection, " we're almost in the stone age, " says Chad Mirkin, Nanosphere's co-founder. " If you go to a doctor's office, they have to take a sample of blood or urine, and you wait for three to five days biting your knuckles, waiting for some results. " The devices one day could be placed in post offices, at water treatment plants or anywhere a biohazard might be released. Mirkin says one day they could be in " every medicine cabinet " in the country. Protecting the homeland For decades, the Pentagon has relied on private industry to help it build better bombs, stealthier aircraft, impenetrable chemical suits, longer-range night-vision goggles and more. Grants for such research come from an obscure federal agency called the Technical Support Working Group (TSWG), which will also fund projects for the Homeland Security department, as well as the Defense Advanced Research Projects Agency (DARPA). Those agencies are funding the research at Medford's lab and in Richmond, Menlo Park and Northbrook. Now the Department of Homeland Security is setting up its own shop to fund similar projects. The department has already given TSWG $30 million, and another $100 million will become available this summer under the department's own new program, to be called the Homeland Security Advanced Research Projects Agency. Some of the projects the department funds will be classified so that would-be terrorists can't find out about the technologies and figure out how to subvert them. But other items on the wish list are public. One is a device that could help border and airport-security workers identify people who are up to no good. When security agents are asked why they search certain cars or question certain airline passengers, they usually can't pinpoint what made them wary. So homeland-security officials want the private sector to devise technology that would mark suspicious people by their physiological responses to questions. Scientists know, for example, that blood rushes to the eye muscles of someone who is lying, and that there are other " thermal signatures " that indicate a person is under stress. The trick is to ensure the device can differentiate between a fearful flier and a would-be bomber. The anti-terror wish list The department's initial wish list, now outlined on the Technical Support Working Group's Web site, also includes: .. Self-decontamination kits that could be given to victims of a chemical attack. The kits must be " easy to open without tools " and include a decontaminant that is " safe to use on skin, wounds and mucus membranes. " Instructions should be easy to follow, the department says, and the kits should cost less than $10. .. Technology to protect commercial and private aircraft from shoulder-fired missiles during takeoffs and landings. It should be " practical " in terms of the cost of retrofitting airplanes and should warn both ground operators and pilots. Any system " must also consider the impact of collateral effects to areas surrounding commercial airports. " .. A sonar-based sea mine detection system that could search harbors, channels and rivers for mines or other " threat objects " have been placed under water. Hundreds of unsolicited proposals already have made their way to homeland-security officials in recent months from companies and universities eager to win grants and contracts. The department's Tasia Scolinos was at an event with Ridge a few months ago when " some guy walked up to me with a manila envelope and said, 'Can you just make sure this gets into the right hands?' " Charles McQueary, a former defense industry executive now serving as the department's undersecretary for science and technology, is assembling a team of experts, including a medical doctor, to evaluate proposals and approve grants. Building a better mousetrap It's not that the department lacks for high-tech gizmos and gadgets to fight terrorism. It already uses state-of-the-art technology for bomb detection, disease tracking and cybersecurity. But someone can always build a better mousetrap. " This is not something where we're going to reach an end state and say, 'We have the perfect homeland-security protection,' " McQueary says. Over time, any detection or prevention device is bound to become outdated as technology advances. What's more, he warns: " The potential threats can also become more sophisticated.
