A trio of researchers from Harvard University, Universidad de Navarra and McGill University has found evidence that suggests fewer women receiving biomedical patents means that fewer inventions for devices or drugs to treat women are being developed. In their paper published in the journal Science, Rembrand Koning, Sampsa Samila and John-Paul Ferguson describe their study of patents awarded to inventors and what they found. Fiona Murray, with MIT, has published a commentary in the same journal issue outlining the work by the researchers in this new effort and describes how their findings fit in with those of other researchers who have looked into the issue of gender bias in the sciences.
