Every year, more than 2 million peer-reviewed research papers are published—far too many for any individual scientist to digest. Machines, however, don’t share this human limitation. BenevolentAI has created algorithms that scour research papers, clinical trial results and other sources of biomedical information in search of previously overlooked relationships between genes, drugs and disease. BenevolentAI CEO Joanna Shields was an executive at companies such as Google and Facebook, and then the U.K.’s Minister for Internet Safety and Security, before joining BenevolentAI. A frequent critic of the tech industry’s lapses in protecting young people from exploitation and abuse online, Shields sees BenevolentAI as an opportunity to harness technology’s power for good. “All of us have family members, friends who are diagnosed with diseases that have no treatment,” she says. “Unless we apply the scaling and the principles of the technology revolution to drug discovery and development, we’re not going to see a change in that outcome anytime soon.” —Corinne Purtill
Whenever the world’s biggest retailer aims its gigantic footprint at a new market, the ground shakes. In September, Walmart opened its first Health Center, a medical mall where customers can get primary care, vision tests, dental exams and root canals; lab work, X-rays and EKGs; counseling; even fitness and diet classes. The prices are affordable without insurance ($30 for an annual physical; $45 for a counseling session), and the potential is huge. In any given week, the equivalent of half of America passes through a Walmart. “When I first started here … [I] thought, That can’t be true,” says Sean Slovenski, a former Humana exec who joined Walmart last year to lead its health care push. If the concept spreads, repercussions await in every direction. Like Walmart’s merchandise suppliers, doctors and other medical pros may need to adjust to the retailer’s everyday low prices. Still, cautions Moody’s analyst Charles O’Shea: “Health care is multiple times harder than selling food.”—Don Steinberg
