Genetics and Immortality

  • Jenny Graves wins Australia’s $250,000 prime minister’s prize for science
    Graves’ groundbreaking genetic work includes the ‘throwaway line’ that the male y chromosome may one day go extinctJenny Graves transformed our understanding of how sex chromosomes work, and led to the realisation that the human male Y chromosome may be on a path to extinction. For that and a slew of other groundbreaking work, Graves has been awarded Australia’s top science prize.Graves, now at the University of Melbourne, helped pioneered the field of “comparative genomics”, ...
