California Gov. Jerry Brown vetoed a bill late Sunday that would have, among other things, capped payments at lower Medicare rates for dialysis facilities that have financial ties to charities that subsidize patients' commercial insurance.

Why it matters: It's a huge win for dialysis companies like DaVita, and for and charities linked to the dialysis industry — like the American Kidney Fund, which lobbied heavily against the bill. Now the industry will look to defeat a midterm ballot measure that would place a much more restrictive cap on dialysis clinics' profits.

More Republicans say they're wearing masks

Data: Axios/Ipsos poll; Chart: Andrew Witherspoon/Axios

Nearly two-thirds of Americans — and a noticeably increasing number of Republicans — say they’re wearing a face mask whenever they leave the house, according to the latest installment of the Axios-Ipsos Coronavirus Index.

Why it matters: A weakening partisan divide over masks, and a broad-based increase in the number of people wearing them, would be a welcome development as most of the country tries to beat back a rapidly growing outbreak.

Buildings are getting tested for coronavirus, too

Testing buildings — not just people — could be an important way to stop the spread of the coronavirus.

Why it matters: People won't feel safe returning to schools, offices, bars and restaurants unless they can be assured they won't be infected by coronavirus particles lingering in the air — or being pumped through the buildings' air ducts. One day, even office furniture lined with plants could be used to clean air in cubicles.

Three missions from three different nations are heading to Mars in the next month — including one from the United Arab Emirates, a newer player in planetary exploration that is expected to launch its first spacecraft to the Red Planet this evening.

Why it matters: More nations are now going to space as the costs of launch and development are driven down. Mars is a step farther that is reserved for those with the most ability and resources — missions to the planet are a mark of scientific and technical prowess on the global stage.
