The Research Parasite Award is an honor given annually at the Pacific Symposium on Biocomputing to recognize scientists who study previously-published data in ways not anticipated by the researchers who first generated it. The tongue-in-cheek name of the award refers to a New England Journal of Medicine editorial that coined the term "research parasite" to disparage such work. The idea was first suggested on Twitter by Iowa State University researcher Iddo Friedberg shortly after the editorial was published, and was then brought to life by Casey Greene, a pharmacologist at the University of Pennsylvania. Two Research Parasite Awards are given to recognize scientists who have made outstanding and rigorous contributions to analysis of secondary data in biology. Recipients must reuse data generated by someone else to extend, replicate, or disprove a research study in a reproducible manner. The junior parasite award recognizes an outstanding contribution from an early career scientist such as a postdoctoral, graduate, or undergraduate trainee. The senior parasitism award recognizes an individual who has engaged in exemplary research parasitism for a sustained period of time. Since the launch of the award in 2017, a travel grant to attend the Pacific Symposium on Biocomputing has been provided to the junior parasite award winner by GigaScience. Starting for the 2019 award year the awards are supported in part by an endowment housed at the University of Pennsylvania. The Research Symbiont Awards, inspired by the Research Parasite Award, was founded by J. Brian Byrd, a physician-scientist at the University of Michigan. Recognizing exemplars in the practice of data sharing, they are given to scientists working in any area of study who have shared data beyond the expectations of their field. Unlike a parasite, naming the data sharing award after symbionts helps stress that this process can be mutually beneficial to the data producing "host" because it increases the scientific impact of their investigators. From 2021 the award has been sponsored by the Wellcome Trust and Dragon Master Foundation. The 2021 winners of the General Symbionts prize were Zhang Yongzhen and Edward C. Holmes for their sharing of the sequence of the first SARSCov2 genome. Nomination and selection procedures Recipients self-nominate using a letter that references their published manuscripts that exemplify data reuse in a manner that enhances reproducibility. These published manuscripts should describe original scientific research that involves data re-use, or the secondary analysis of shared data and that extend,
