Oswald Theodore Avery Jr. was a Canadian-American physician and medical researcher. The major part of his career was spent at the Rockefeller Hospital in New York City. Avery was one of the first molecular biologists and a pioneer in immunochemistry, but he is best known for the experiment that isolated DNA as the material of which genes and chromosomes are made.
Mycobacterium tuberculosis, also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. First discovered in 1882 by Robert Koch, M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid. This coating makes the cells impervious to Gram staining, and as a result, M. tuberculosis can appear weakly Gram-positive. Acid-fast stains such as Ziehl–Neelsen, or fluorescent stains such as auramine are used instead to identify M. tuberculosis with a microscope. The physiology of M. tuberculosis is highly aerobic and requires high levels of oxygen. Primarily a pathogen of the mammalian respiratory system, it infects the lungs. The most frequently used diagnostic methods for tuberculosis are the tuberculin skin test, acid-fast stain, culture, and polymerase chain reaction.
Stanley Norman Cohen is an American geneticist and the Kwoh-Ting Li Professor in the Stanford University School of Medicine. Stanley Cohen and Herbert Boyer were the first scientists to transplant genes from one living organism to another, a fundamental discovery for genetical engineering. Thousands of products have been developed on the basis of their work, including human growth hormone and hepatitis B vaccine. According to immunologist Hugh McDevitt, "Cohen's DNA cloning technology has helped biologists in virtually every field". Without it, "the face of biomedicine and biotechnology would look totally different." Boyer cofounded Genentech in 1976 based on their work together, but Cohen was a consultant for Cetus Corporation and declined to join. In 2022, Cohen was found guilty of having committed fraud in misleading investors into a biotechnology company he founded in 2016, and paid $29 million in damages.
Mario Ramberg Capecchi is an Italian-born molecular geneticist and a co-awardee of the 2007 Nobel Prize in Physiology or Medicine for discovering a method to create mice in which a specific gene is turned off, known as knockout mice. He shared the prize with Martin Evans and Oliver Smithies. He is currently Distinguished Professor of Human Genetics and Biology at the University of Utah School of Medicine.
Mycobacterium smegmatis is an acid-fast bacterial species in the phylum Actinomycetota and the genus Mycobacterium. It is 3.0 to 5.0 μm long with a bacillus shape and can be stained by Ziehl–Neelsen method and the auramine-rhodamine fluorescent method. It was first reported in November 1884 by Lustgarten, who found a bacillus with the staining appearance of tubercle bacilli in syphilitic chancres. Subsequent to this, Alvarez and Tavel found organisms similar to that described by Lustgarten also in normal genital secretions (smegma). This organism was later named M. smegmatis.
Bruce Michael Alberts is an American biochemist and the Emeritus Chancellor’s Leadership Chair in Biochemistry and Biophysics for Science and Education at the University of California, San Francisco. He has done important work studying the protein complexes which enable chromosome replication when living cells divide. He is known as an original author of the "canonical, influential, and best-selling scientific textbook" Molecular Biology of the Cell, as an Editor-in-Chief of Science magazine. He was awarded the National Medal of Science for "intellectual leadership and experimental innovation in the field of DNA replication, and for unparalleled dedication to improving science education and promoting science-based public policy" in 2014.
A mycobacteriophage is a member of a group of bacteriophages known to have mycobacteria as host bacterial species. While originally isolated from the bacterial species Mycobacterium smegmatis and Mycobacterium tuberculosis, the causative agent of tuberculosis, more than 4,200 mycobacteriophage have since been isolated from various environmental and clinical sources. 2,042 have been completely sequenced. Mycobacteriophages have served as examples of viral lysogeny and of the divergent morphology and genetic arrangement characteristic of many phage types.
James Alan Shapiro is an American biologist, an expert in bacterial genetics and a professor in the Department of Biochemistry and Molecular Biology at the University of Chicago.
Jack William Szostak is a Canadian American biologist of Polish British descent, Nobel Prize laureate, University Professor at the University of Chicago, former Professor of Genetics at Harvard Medical School, and Alexander Rich Distinguished Investigator at Massachusetts General Hospital, Boston. Szostak has made significant contributions to the field of genetics. His achievement helped scientists to map the location of genes in mammals and to develop techniques for manipulating genes. His research findings in this area are also instrumental to the Human Genome Project. He was awarded the 2009 Nobel Prize for Physiology or Medicine, along with Elizabeth Blackburn and Carol W. Greider, for the discovery of how chromosomes are protected by telomeres.
Bernard Nathan Fields was an American microbiologist and virologist. Fields was a member of the National Academy of Sciences.
Stephen Joseph Elledge is an American geneticist. He is the current Gregor Mendel Professor of Genetics and of Medicine at the Department of Genetics of Harvard Medical School and in the Division of Genetics of the Brigham and Women's Hospital. His research is focused on the genetic and molecular mechanisms of eukaryotic response to DNA damage and is known as the discoverer of the DNA damage response (DDR).
The Szent-Györgyi Prize for Progress in Cancer Research, established by National Foundation for Cancer Research (NFCR) and named in honor of Albert Szent-Györgyi, Nobel laureate and co-founder of NFCR, has been awarded annually since 2006 to outstanding researchers whose scientific achievements have expanded the understanding of cancer and whose vision has moved cancer research in new directions. The Szent-Györgyi Prize honors researchers whose discoveries have made possible new approaches to preventing, diagnosing and/or treating cancer. The Prize recipient is honored at a formal dinner and award ceremony and receives a $25,000 cash prize. In addition, the recipient leads the next "Szent-Györgyi Prize Committee" as honorary chairman.
