Furthermore, group 2B only indicates a credible association between disease and exposure but does not rule out confounding effects with reasonable confidence. A causal relationship has yet to be established. [11] Epidemiological studies look for statistical correlations between EM exposure in the field and specific health effects.
The name "Moscow Signal" was used by United States intelligence officials [2] to describe the low power signals recorded in the embassy. The microwave transmissions caused an irradiance in the embassy of only 5 μW/cm 2, [2] which is one-thousandth the maximum permissible leakage from a microwave oven and far below what would be needed to heat anything.

There is high uncertainty regarding correlations between long-term, low-level exposure to ELF fields and a number of health effects, including leukemia in children. In October 2005, WHO convened a task group of scientific experts to assess any risks to health that might exist from "exposure to ELF electric and magnetic fields in the frequency ...
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
The Distant Early Warning (DEW) Line, constructed in the late 1950s, was reaching obsolescence in the 1980s.With the signing of North American Air Defence Modernization agreement at the "Shamrock Summit" between Prime Minister Mulroney and President Reagan in Quebec City on 18 March 1985, the DEW Line began its eventual upgrading and transition becoming the North Warning System (NWS) of today.
Amid growing anxieties surrounding reported drone sightings, the FBI has issued a warning against a new trend of pointing lasers at aircrafts.

After the conclusion of World War II, U.S. military researchers obtained formulas for the three nerve gases developed by the Nazis—tabun, soman, and sarin.. In 1947, the first steps of planning began when Dr. Alsoph H. Corwin, a professor of chemistry at Johns Hopkins University [4] [5] wrote the Chemical Corps Technical Command positing the potential for the use of specialized enzymes as so ...
