**Prof. J. H. Sang at the University of Sussex** Dr. J. H. Sang has been appointed as a professor in the School of Biology at the University of Sussex. His early career focused on zoology, and he has held various research positions at the University of Aberdeen, St. John's College, Cambridge, and the Agricultural Research Council in Edinburgh. His research interests have centered on the interactions between organisms and their environment, particularly using Drosophila melanogaster. He developed methods for sterile culture on chemically defined media and has recently explored biochemical genetics and tumor formation in Drosophila. **Prof. J. C. Mitchell at the University of Manchester** Prof. J. C. Mitchell has been appointed to the newly established chair of Urban Sociology at the University of Manchester. He has a background in African studies and sociology, with extensive research experience in colonial territories, including Nyasaland and Northern Rhodesia. His work has focused on urbanization, tribal studies, and the social sciences. He has held various academic positions and has served on numerous international committees, including the United Nations African Committee on Social Sciences. **The United Nations Scientific Committee on the Effects of Atomic Radiation (1964 Report)** The 1964 report of the United Nations Scientific Committee on the Effects of Atomic Radiation focuses on two specific topics: environmental contamination by nuclear explosions and the risks of inducing malignant diseases by radiation in humans. The report notes that long-lived fission products like strontium-90 and caesium-137 will remain in the stratosphere for years, leading to revised "dose commitments" for the global population. The risks of carcinogenesis are assessed based on data from humans and animals, with a linear relationship between radiation dose and cancer development assumed. The risk of leukemia is estimated at 1-2 cases per year per rad per million exposed persons, with higher risks for in utero exposure. The overall risk of all malignancies is unlikely to exceed this estimate significantly. **Medical Research Council of Ireland** The Medical Research Council of Ireland, established 25 years ago, initially struggled with limited resources and could not support substantial clinical research programs. However, a substantial increase in funding in 1959 allowed the Council to appoint clinical research fellows and provide essential equipment. The Council has since supported various research areas, including endemic goitre, tuberculosis chemotherapy, and cell metabolism. It has also assisted in public health investigations, such as the National Nutrition Survey.**Prof. J. H. Sang at the University of Sussex** Dr. J. H.
