- 01 Jan ARPANET transitions to TCP/IP, marking the birth of the Internet: On January 1, 1983, the ARPANET officially switched from the Network Control Protocol (NCP) to the Transmission Control Protocol/Internet Protocol (TCP/IP) suite. This transition, known as 'flag day,' required all ARPANET hosts to adopt TCP/IP, laying the foundation for the modern Internet. source: internetsociety.org
- 07 Apr Ancient human skeleton discovered in Egypt: On April 7, 1983, a skeleton estimated to be between 60,000 and 80,000 years old was unearthed in Egypt's Nile Valley. The nearly complete skeleton, encased in sandstone, was transported to the Smithsonian Institution's National Museum of Natural History for further study. Scientists are investigating whether the remains belong to a Neanderthal or a primitive human ancestor, aiming to shed light on human evolution. source: upi.com
- 11 May Comet IRAS–Araki–Alcock's close approach to Earth: On May 11, 1983, Comet IRAS–Araki–Alcock (C/1983 H1) made its closest known approach to Earth, passing at a distance of approximately 0.0312 AU (4.67 million kilometers). Discovered by the Infrared Astronomical Satellite (IRAS) and amateur astronomers George Alcock and Genichi Araki, the comet became visible to the naked eye, appearing as a bright, circular cloud about the size of the full moon. This event marked the closest cometary approach to Earth in 200 years, surpassed only by Lexell's Comet in 1770. source: jpl.nasa.gov
- 20 May First publication identifying HIV as cause of AIDS: On May 20, 1983, Luc Montagnier and his team at the Pasteur Institute published a groundbreaking paper in the journal Science, identifying a new retrovirus, later named HIV, as the cause of AIDS. This discovery marked a pivotal moment in understanding the disease and laid the foundation for subsequent research and treatment developments. source: pasteur.fr
- 07 Jun Asteroid 3152 discovered by astronomers A. Gilmore and P. Kilmartin: On June 7, 1983, astronomers A. Gilmore and P. Kilmartin discovered asteroid 3152, contributing to the ongoing scientific documentation and understanding of celestial bodies in our solar system. source: takemeback.to
- 25 Jul First baboon conceived via in vitro fertilization: On July 25, 1983, a baboon named E.T. was born at the Southwest Foundation for Research and Education in San Antonio, Texas. E.T. was the first non-human primate conceived through in vitro fertilization, marking a significant milestone in reproductive science. The procedure involved placing four fertilized embryos into the oviduct of a female baboon, leading to a successful pregnancy and birth. source: upi.com
- 10 Sep Felix Bloch, pioneering physicist, dies at 77: Felix Bloch, a Swiss-born American physicist renowned for his contributions to nuclear magnetic resonance, passed away on September 10, 1983, in Zurich, Switzerland, at the age of 77. He was awarded the Nobel Prize in Physics in 1952 for his work on nuclear induction, which laid the foundation for techniques now widely used in medical diagnostics. source: washingtonpost.com
- 29 Dec Discovery of Polymerase Chain Reaction: In 1983, Kary B. Mullis, an American biochemist, invented the Polymerase Chain Reaction (PCR) technique, revolutionizing molecular biology by enabling rapid amplification of specific DNA sequences. This innovation has had profound impacts on genetic research, diagnostics, and forensic science. source: genome.gov
