Franklin W. Stahl, 95, Dies; Helped Create a ‘Beautiful' DNA Experiment
Franklin W. Stahl, a molecular biologist who helped create a methodology to confirm how DNA replicates that was so elegant it has been remembered for more than five decades as 'the most beautiful experiment in biology,' died on April 2 at his home in Eugene, Ore. He was 95. The cause was congestive heart failure, his son Andy Stahl said. His death was not widely reported at the time, and there was no announcement about it from the University of Oregon in Eugene, where he was a professor and researcher. At his death, Dr. Stahl was an emeritus professor of molecular biology and genetics at the university's Institute of Molecular Biology. He had been at the university since 1959. Dr. Stahl's name and that of his collaborator, Matthew Meselson, were immortalized by the Meselson-Stahl Experiment, which is referenced in biology textbooks and taught in molecular genetics courses worldwide. In 2015, 'Helix Spirals,' a musical tribute to the experiment, was composed by Augusta Read Thomas and performed by a string quartet in Boston. The two biologists proved a theory advanced by the Nobel Prize winners James Watson and Francis Crick, who discovered DNA's helical structure in 1953. Watson and Crick posited in the journal Nature that DNA replicates in a so-called semi-conservative fashion. In 1958, Dr. Meselson and Dr. Stahl, postdoctoral fellows in Linus Pauling's laboratory at the California Institute of Technology in Pasadena, Calif., proved that Watson and Crick were correct, by using an experiment that was celebrated for its design, execution and results.

Research consumables supply center inaugurated at AIC-CCMB in Hyderabad; it cuts waiting time to get chemical agents
A special 'supply center' providing accessibility to essential research consumables for the life science research community in and around the (AIC-CCMB) Atal Incubation Centre-Centre for Cellular and Molecular Biology campus at Uppal in Hyderabad was inaugurated on Wednesday (June 18, 2025). CSIR-CCMB Director Vinay Kumar Nandicoori dedicated the centre set up by 'Thermo Fisher Scientific' to the researchers in the area including those working at Centre for DNA Fingerprinting & Diagnostics (CDFD), National Institute of Nutrition (NIN) and others, in the presence of AIC-CCMB CEO N. Madhusudana Rao. Steady supply of chemical agents Dr. Kumar said the supply centre promises to reduce the usual time lags in getting the necessary chemical agents like enzymes for research purposes, as steady supply will now be available. 'It will be good for the entire eco-system as procurements otherwise could be cumbersome,' he said. Thermo Fisher's director Jayabharath Reddy said they are committed to support scientific innovation and the new supply center will enable start ups and researchers at CCMB and surrounding institutions to gain access to critical research consumables. 'Specialised consumables have always been a challenge for researchers, sometimes losing months in the process of ordering to delivering. Our centre will be putting essential materials right on campus, enabling faster scientific breakthroughs,' he said The new centre is located adjacent to the company's Centre for Innovation (CFI) established at the AIC-CCMB. The CFI was set up for fostering collaborations and advancing scientific breakthroughs in life sciences. Earlier, AIC-CCMB and Thermo Fisher are also holding a three-day workshop on 'Cell Health Analysis' to enhance technical skills of the researchers in cell based assays used in biomedical research and drug discovery. 'Cell analysis is crucial in developing therapies for cancer and other diseases. This workshop gives researchers hands-on exposure to advanced tools,' said Dr. Rao.
