September 13, 2006 – Pluto is demoted from planetary status

Originally discovered in 1930, Pluto was at that time classed as a planet, and named for the Roman god of the Underworld. However, as the years went by, evidence mounted that it was not truly a major planet. Although it did have moons of its own, it also had an eccentric orbit (which crosses that of Neptune, the next furthest out planet) and a lower mass than any other planet.

The discovery that Pluto was just one of a number of bodies in the Kuiper Belt, many of them with comparable size and mass, also weakened the arguments for considering it a planet. Finally, a new definition of what a planet issued by the International Astronomical Union on August 24, 2006, excluded Pluto. On September 13, Pluto was named a Dwarf Planet, alongside Ceres, Haumea, Makemake, and Eris – all of which, other than Ceres, are also Kuiper Belt objects.

April 13, 1953 — The CIA launches the MK-ULTRA project

CIA director Allen Dulles ordered the creation of the MKUltra project intending it to create techniques to fight what was believed to be an extensive Communist brain-washing program (at various times identified as being conducted by one of, or some combination of, North Korea, China and the USSR). Its scope became broader than that, attempting to create drugs for mind control, for compelling the truth from interrogation subjects, for duplicating the symptoms of various diseases, for stimulating or retarding aging, and more. Often, subjects were experimented on without their knowledge or consent, leading to several nervous breakdowns and at least one confirmed suicide, as people who did not know they were drugged assumed that they were losing their minds.

The project ran from 1953 through to 1973, although many of the records of it were destroyed in 1974 (a measure ordered by CIA director Richard Helms as the Watergate scandal mounted). This lack of records helped to conceal the extent and outcomes of the program when they were investigated by both the Church Committee and the Rockefeller Commission, but enough was found to confirm much of what was suspected of the program, and the information made public. A further investigation took place in 1977, after the discovery of MKUltra records that had escaped the destruction of the rest due to being misfiled. Afterwards, several of those drugged in the program sued the government for the lack of informed consent, not all of them successfully. Even now, it is not clear whether we know everything about the MKUltra program.
