Proliferation / ArsenalsThe first atomic test was detonated by the United States at the Trinity site on July 16, 1945, with a yield approximately equivalent to 20 kilotons. The first hydrogen bomb, codenamed "Mike", was tested at the Enewetak atoll in the Marshall Islands on November 1, 1952, also by the United States. The largest nuclear weapon ever tested was the "Tsar Bomba" of the Soviet Union at Novaya Zemlya on October 30, 1961, with an estimated yield of around 50 megatons. In 1963, all nuclear and many non-nuclear states signed the Limited Test Ban Treaty, pledging to refrain from testing nuclear weapons in the atmosphere, underwater, or in outer space. The treaty permitted underground nuclear testing. France continued atmospheric testing until 1974, while China continued up until 1980. The last underground test by the United States was in 1992, the Soviet Union in 1990, the United Kingdom in 1991, and both France and China continued testing until 1996. After adopting the Comprehensive Test Ban Treaty in 1996, all of these states have pledged to discontinue all nuclear testing. Non-signatories India and Pakistan last tested nuclear weapons in 1998. The most recent nuclear test was announced by North Korea on October 9, 2006. See 2006 North Korean nuclear test for more information.

1. Forensic DNA Analysis - What is Mitochondrial DNA?
January 13, 2008
Mitochondrial DNA is a very useful tool in forensic science. It has been used to identify human remains and perpetrators of a crime. It has also been used to determine ancestry.
In traditional DNA testing, nuclear DNA is used. Nuclear DNA (nDNA) can be removed from any nucleated cell. However, there are cells that do NOT contain nuclear DNA. These cells are called non-nuclear DNA cells. Where else is DNA found? Mitochondria contain DNA. Mitochondria are tiny organelles that live within the cytoplasm of a cell. Their role in a cell is to produce energy used for the cell's metaboli... (read more)

2. Bush sent North Korea $55 Million, but Wanta $4.5 Trillion still not turned over to American people
October 30, 2006
Michael C. Cottrell, treasurer for the Wanta financial group set to repatriate $4.5 trillion into the U.S. economy, said he received documented inside information the Bush administration sent North Korea $55 million the day after it set off a nuclear testing device.
Cottrell's announcement Thursday came as a shock to the world since it previously was thought the U.S. was strongly opposed to North Korea's actions, publicly denouncing the nuclear testing and indicating strong financial sanctions should be imposed.
However, the transfer of money to North Korea, taken from the offshore a... (read more)

3. Creating a strong Immune System for you and your family
October 24, 2006
Staying healthy depends critically on the health of your immune system. Studies show that the supplement 1-3, 1-6 beta glucans is one of the most powerful ways to support the immune system. So much so that the US Government is now testing one brand of beta glucans with a view to stockpiling it as a protective measure against the possibility of nuclear radiation – see later.
Unfortunately, we live in a rather toxic world. Air pollution, pesticides, herbicides, poisons and pollutants enter our food chain through water, soil and air – and all these create significant stress to our immune sy... (read more)
