Chasing the AIDS virus
In 1981 a short story in Science News noted an uptick in a rare form of cancer and pneumonia in gay men (11/14/81, p. 309). The cause of what the story called a “puzzling outbreak,” the human immunodeficiency virus (below, reproducing inside a cell), wouldn’t be named for another five years (4/26/86, p. 265). In the meantime, the scientific community struggled to link this virus to AIDS, facing “a grim picture of a disease that remains one step ahead of the researchers seeking ways to stop it” (4/27/85, p. 260). As the outbreak became an epidemic, Science News reported on the first copying of the virus’s genetic blueprints and the first screening tests (1/19/85, p. 36). A breakthrough came in 1986 with the use of azidothymidine, or AZT. The drug, which promised to “prolong the lives of an estimated 600,000 people in the United States” (8/26/89, p. 135), helped make AIDS a treatable disease instead of a death sentence. — Devin Powell

1981 | AIDS detected An outbreak of two rare and serious diseases among homosexual men — Kaposi’s sarcoma and Pneumocystis pneumonia — mark the discovery of what would come to be known as AIDS (11/14/81, p. 309).
1982 | Ribozyme Thomas Cech and colleagues report that RNA can function like an enzyme to trigger the synthesis of proteins (11/27/82, p. 342). N
1984 | Brown dwarf Astronomers for the first time think they have evidence of a brown dwarf — a celestial object too big to be a planet but insufficiently massive to become a star (12/15/84, p. 373).
1985 | GMOs U.S. federal agencies approve the first two experimental releases of genetically modified organisms: antifrost bacteria for strawberries and tumor-resistant tobacco plants (11/23/85, p. 324).
1985 | Buckyballs Chemists identify a soccerball–shaped configuration of carbon atoms, nicknamed a buckyball (11/23/85, p. 325). N
1987 | Ozone protection The Montreal Protocol to phase out stratospheric ozone-destroying chlorofluorocarbons gets enough signatures; it goes into effect January 1, 1989 (9/26/87, p. 196; 11/19/88, p. 333).
1987 | Dino wipeout Grains of shocked quartz from around the world offer further evidence that a meteorite or asteroid struck the Earth more than 65 million years ago, causing mass extinctions of life — including dinosaurs (5/16/87, p. 309).
1989 | Cold fusion Martin Fleischmann and B. Stanley Pons report on benchtop nuclear reactions that they describe as “cold fusion” but that are never confirmed (4/1/89, p. 196; 4/8/89, p. 212; 4/15/89, p. 229; 4/22/89, p. 244).
