Sure, there’s plenty about the sorry state of the healthcare industry that one could gripe about. But why be negative when instead you can consider the attitude-changing and cancer-doctor-wrangling efforts of billionaire philanthropist Sean Parker? And yes, big data is no panacea for curing cancer. But instead let’s celebrate the work of Greg Simon, executive director of the White House’s cancer “moonshot” task force, who is helping to foster a culture of information sharing among researchers. Or consider the pioneering work of University of Utah radiologist and health system CEO Vivian Lee, who got an MBA and returned to medicine with a focus on cost accounting, of all things. Lee’s epiphany: Simply nudging doctors to understand the costs of the procedures, devices, and tests they order unleashes their competitive juices to be more economical in how they practice medicine.

The really positive news here is that Fortune has once again worked its “live” media magic by starting a conference that brought together a unique blend of healthcare practitioners, administrators, and policymakers to discuss real solutions to improving what is arguably the most important industry in the land. All the coverage, including videos from many of the panels and interviews, is available here. My colleagues and I already can’t wait until next year for this conference to happen again.

Speaking of waiting ‘til next year, or in this case, not having to wait, did I mention the Chicago Cubs won the World Series?

Have a winning day.

Facebook investors are skittish about the future. Despite reporting a bang-up third quarter—the social network's revenue grew 56% to just over $7 billion—Facebook's stock slipped at least 7% in after-hours trading Wednesday. The cause? CFO David Wehner's comments that growth could slow "meaningfully" as Facebook visitors reach their advertising saturation point. (Fortune, New York Times)

Department store Kohl's will sell Apple Watch. The retailer plans to merchandise the wearables technology within its fitness department, starting Nov. 15, rather than alongside other electronics gadgets.

(Fortune, Bloomberg)

Mobile apps still growing like gangbusters. The market could reach $189 billion by 2020, compared with $70 billion last year, according to a new forecast by analytics company App Annie. Growth will be particularly strong for shopping and transportation apps. (VentureBeat)
