The whole point of artificial-intelligence systems is that they can learn — but they still have to start somewhere. And the nascent field of health care AI is still focused on those early building blocks.

Where it stands: Google already has a leg up on some of its competitors, because of the data it already collects through search and Gmail, NPR reports.

What they're saying: "As companies like Google and other traditional consumer-oriented companies start moving into this space, it is certainly clear that they bring the capability of taking much of the information they have about us and be able to apply it," said Reed Tuckson, a member of the advisory board for Verily, Alphabet's health care arm.

What else: On top of that, Google is working with researchers at Duke and Stanford to recruit volunteers — the goal is to get 10,000 of them — who contribute far more data.

  • Participants fill out regular health surveys, use a tool that tracks their sleep, and wear a watch that monitors their heart rate and steps (although the watch seems to not work perfectly).
  • "It's sort of a way of donating your body while it's still alive," one participant told NPR.

Former Attorney General Jeff Sessions has lost the Republican nomination for Senate to Tommy Tuberville in Alabama in Tuesday night’s primary runoff, AP reports.

Why it matters: Sessions had been the underdog in the race against former Auburn University head football coach Tommy Tuberville, who had the backing of President Trump. Tuberville will now face off against Sen. Doug Jones (D-Ala.) in November, who is considered to have one of the most vulnerable Democratic Senate seats in the country.

Bank CEOs brace for worsening economic scenario

Wells Fargo swung to its first loss since the financial crisis — while JPMorgan Chase and Citigroup reported significantly lower profits from a year earlier — as the banks set aside billions of dollars more in the second quarter for loans that may go bad.

Why it matters: The cumulative $28 billion in loan loss provisions that banks have so far announced they’re reserving serves as a signal they’re preparing for a colossal wave of loan defaults as the economy slogs through a coronavirus-driven downturn.
