U.S. NavyStrong government counterterrorism measures in response to terrorist attacks may cause economic damage and help terrorists groups stir up popular support for their agendas, often aiding them considerably in achieving their goals, suggests a new study from Washington University in St. Louis.

Researchers at Washington University School of Medicine in St. Louis report they have developed an agent that protects cells from the lethal effects of radiation, regardless of whether it is given before or after exposure. Using this agent in mice, the investigators found that the treatment helped shield rapidly dividing cells that are most vulnerable to radiation-induced death, providing proof in principle that it is possible to fend off radiation damage.

Current levels of defense spending represent less than 5 percent of the nation’s gross domestic product (GDP), says Murray Weidenbaum, the Mallinckrodt Distinguished University Professor at Washington University in St. Louis. He says that the cost of today’s war pales in comparison to military outlays of about 35 percent of GDP at the peak of World War II; 15 percent of GDP for the Korean War; 10 percent for Vietnam and 6 percent for the Gulf War.

Anthrax is nasty stuff. An environmental engineer at WUSTL uses smart catalysts in his device that can detect the presence of airborne anthrax and disable it.An environmental engineer at Washington University in St. Louis with his doctoral student has patented a device for trapping and deactivating microbial particles. The work is promising in the war on terrorism for deactivating airborne bioagents and bioweapons such as the smallpox virus, anthrax and ricin, and also in routine indoor air ventilation applications such as in buildings and aircraft cabins.

Now, however, it is being touted as a powerful and effective tool for an array of new applications — everything from screening potential terrorists in the nation’s airports to catching wayward spouses in messy marital disputes. Despite its booming popularity, recent federally sponsored studies have found little evidence that existing voice-stress technologies are capable of consistently detecting lies and deceptions. “You could have gotten better results by flipping a coin,” says Washington University in St. Louis psychologist Mitchell S. Sommers, lead investigator on a recent voice-stress study.

John Lockwood programs the data enabling device to stop the SoBig worm.A computer scientist at Washington University in St. Louis has developed technology to stop malicious software – malware – such as viruses and worms long before it even has a chance to reach computers in the home and office. John Lockwood, Ph.D., an assistant professor of computer science at Washington University, and the graduate students that work in his research laboratory have developed a hardware platform called the Field-programmable Port Extender (FPX) that scans for malware transmitted over a network and filters out unwanted data.
