Work
Bacteriophages are viruses that attach themselves to bacteria, emptying their genetic material into them. At times, many new phage are created quickly, while at other times, new phage are formed only several bacterial generations later. In the early 1950s André Lwoff successfully explained how this process, known as lysogeny, works. The bacteriophage's genes are incorporated into the bacteria's genetic material, but remain latent until a trigger factor causes new phage to be formed. Lwoff also showed that ultraviolet light can be one such factor.
Nobel Prizes and laureates
Six prizes were awarded for achievements that have conferred the greatest benefit to humankind. The 12 laureates' work and discoveries range from proteins' structures and machine learning to fighting for a world free of nuclear weapons.
