---|---|---|---|
The year 1984 in science and technology involved some significant events.
Astronomy and space exploration
- February 7 – Astronauts Bruce McCandless II and Robert L. Stewart make the first untethered space walk.
- The National Radio Astronomy Observatory in the United States converts the 36-foot radio telescope on Kitt Peak (originally built in 1967) to the ARO 12m Radio Telescope.
Biology
- First known case of Bovine spongiform encephalopathy, in England.[1]
- The enzyme telomerase is discovered by Carol W. Greider and Elizabeth Blackburn in the ciliate Tetrahymena.[2]
- Danish physiologist Steen Willadsen first successfully uses cells from early embryos to clone a mammal (sheep) by nuclear transfer at the British Agricultural Research Council's Institute of Animal Physiology, Cambridge.[3][4]
Chemistry and physics
- Peter Kramer[5] and Dan Shechtman[6] publish their discoveries of what will soon afterwards be named quasicrystals.[7]
- Hiroshi Kobayashi and colleagues announce synthesis of tetrakis(3,5-bis(trifluoromethyl)phenyl)borate ("BARF").[8]
Computer science
- January 24 – Apple Computer place the Macintosh personal computer on sale in the United States. It will be the first successful PC to use a graphical user interface.
- June 6 – The Tetris tile-matching video game, designed by Alexey Pajitnov, is launched in the Soviet Union.[9]
History of science
- Robert Gwyn Macfarlane publishes Alexander Fleming: The Man and the Myth.
Paleontology
- The fossil skeleton of the hominid "Turkana Boy" is discovered in Kenya.
Physiology and medicine
- February 3 – Dr. John Buster and the research team at Harbor-UCLA Medical Center announce history's first embryo transfer from one woman to another resulting in a live birth.
- April 22 – Dr. Robert Gallo and Margaret Heckler of United States Public Health Service announce the discovery of HTLV-III as the virus that causes AIDS.
Technology
- July 21 – In Jackson, Michigan, a factory robot crushes a worker against a safety bar in apparently the first robot-related death in the United States.
