...al, general startle response, followed by a longer defensive response more directed toward protection from a threat. By measuring the electrical activity of the animals' eye muscles during the response, the researchers could follow it in greater detail. Significantly, they found that the initial startle respon...Managing occupational exposures to potential bioterrorist agents
...n that program ended in 1969, the focus shifted to defensive research, which involves less frequent use of high concentrations of agent. Also, laboratory practices and safety measures have evolved over time, bringing improvements in engineering controls (such as directional airflow), advances in biosafety equ...Strep disrupts blood clotting to infect humans
...rtant human pathogen." To further demonstrate the defensive importance of the clotting system, the researchers administered a substance derived from snake venom that degrades another clotting protein, fibrinogen, and found that it too greatly increased the mice's mortality from this streptococcus infection. ...Streptococcus infects humans by thwarting blood clotting

In another experiment to demonstrate the defensive importance of the clotting system, the researchers administered a substance derived from snake venom that degrades another clotting protein, fibrinogen, discovering that the treatment greatly increased the mice's mortality from this streptococcus inf...Anti-cancer compound in vegetables found to block late-stage breast-cancer cell growth
...cer. Previous reports have shown that SUL induces defensive mechanisms that are effective in protecting normal cells from the initiation of cancer. "More than 10 years ago, researchers at Johns Hopkins University reported that SUL is a potent inducer of enzyme systems that can defend against carcinogens," Si...
