Owkin, the predictive analytics startup backed by Alphabet’s GV, has announced the launch of its AI-powered medical research network. Comprised of 30 US and EU hospitals and research institutions, the Owkin Loop Network looks to help researchers train their predictive health models on a greater scale of real-world data, as well as share any insights gained between participating researchers and organizations.

“Access to patient data is critical for improving medical research,” Dr. Thomas Clozel co-founder and CEO of Owkin, said in a statement. “But researchers can’t share sensitive patient data, relegating knowledge to a tiny group of researchers at each hospital. We founded Owkin to change this, to efficiently and intelligently transform hospital-level clinical data into predictive models to advance medical research all over the world. If we can transform the world’s clinical data into broadly accessible research knowledge, we believe we can fundamentally advance medical research and have an incredibly powerful impact in solving the most important medical challenges.”

A low-cost smartphone-based device developed by researchers at the Brigham and Women’s Hospital was able to predict ovulation with 99 percent accuracy, according to a small study published by the Royal Society of Chemistry’s Lab on a Chip. The study included six healthy women from ages 20 to 22 who had a history of normal menstrual cycles, did not consume tobacco and alcohol and did not use hormonal contraceptions during the study period. The technology employs artificial intelligence and requires a small sample of saliva from the user. The device can detect fern patterns from saliva that is dried on a micro fluid device.
