- Richard P. Binzel devises the original of what will become the Torino Scale for categorizing the impact hazard associated with near-Earth objects.[2]
- The first brown dwarf – Teide 1 – is discovered.[3]
Biology edit
- March 24 – Patrick Callaerts and colleagues publish the first classic demonstration of the role of the PAX6 gene in the development of eyes.[4]
- The genome of Haemophilus influenzae is the first genome of a free living organism to be sequenced.

Computer science edit
- January 27 – Prodigy (online service) offers access to the World Wide Web.[6]

Medicine edit

- December 6 – The United States Food and Drug Administration approves Saquinavir, the first protease inhibitor to treat HIV/AIDS. Within 2 years of its approval, annual deaths from AIDS in the United States fall from over 50,000 to approximately 18,000.[12]
Neuroscience edit
- The RELN gene and Reelin protein are discovered by Gabriella D'Arcangelo and colleagues, solving the mystery behind the formation of "inverted cortical layers" in the brain of reeler mutant mice, and sparking an avalanche of research into the Reelin's role in neurodevelopment.
Physics edit
Psychology edit
- Elizabeth Loftus describes the "Lost in the mall technique" as a demonstration that confabulations can be created through suggestions to experimental subjects.[16]
