Article Abstract:
Bayesian methods for estimating mutation rates from fluctuation experiments were developed and compared with four traditional estimation approaches. Using results from 10,000 simulated experiments, the Bayesian procedures were determined to be as efficient as the best traditional estimation procedure. Among the different Bayesian procedures, it was determined that the estimator which uses one-per-square meter as the prior probability density function and quadratic loss function was the best.

Article Abstract:
A biologist recalls his first, and subsequent, meetings with Nobel Prize winner Thomas Hunt Morgan, chairman of the biology department at Caltech, who also happens to have wielded considerable influence in his life. Morgan, who founded the Division of Biology at Caltech in 1928, was noted for his skepticism and abhorrence of speculation that led him to develop a passion for research. Some of his well-known experiments focused on Drosophila genetics and marine animals.

Article Abstract:
Biologist Lancelot Hogben was known for his contributions in the fields of medical statistics, comparative zoology and human and medical genetics. Hogben, who was born in Swansea, U.K., on Dec. 9, 1895, is the inventor of the standard pregnancy test and one of the founders of the Society for Experimental Zoology. Hogben's work on genetics involve the interdependence of nature and nurture in the study of the origin of traits.
