Healthy patients who received the first doses of Moderna's coronavirus vaccine appeared to have generated antibody responses to the virus, according to early phase one trial data released by the company Monday.

The big picture: This is an early snapshot of a small sample size within a trial that is focused on the vaccine's safety. This is a positive first step, but still a first step.

New York Gov. Andrew Cuomo (D) said at a press briefing Sunday that not enough New Yorkers are getting tested for the coronavirus, even though the state has significantly scaled up its capacity.

Driving the news: Cuomo announced that New York is expanding its eligibility for diagnostic testing to include anyone who is returning to work as part of the state's "phase one" reopening — which includes people in construction, manufacturing and curbside retail.

A rolling, living experiment — and preview of coming attractions for the rest of the country — has begun in Wisconsin, after a surprise court ruling made the Badger State the first in the nation where businesses can reopen.

The state of play: Wisconsin Gov. Tony Evers (D) warned of “massive confusion” after his stay-at-home order was thrown out Wednesday night by the state's Supreme Court.

The coronavirus pandemic "comes at a time when the U.S. federal government’s investments in science are at the lowest levels in many years," Abby Joseph Cohen and Michael Hao Wu of Goldman Sachs Research write in a recent note to clients.

Where it stands: "The federal government now plays a much smaller role in advancing science than it did in the past. The consequence of this trend is particularly damaging for basic research, which depends on the government as its main source of funding."

CityLab has some fascinating reporting on European cities making changes to their transit policy that will outlast the immediate crisis and, more intriguingly, perhaps become permanent after initial reemergence from lockdown.

Driving the news: It notes that in the near term, transit policies and systems will change in recognition that people should not be — and don't want to be — crammed into buses and trains cheek-by-jowl.

Most of America has been ordered to shelter at home to help curb the spread of the coronavirus, but that can be tricky for people who live with roommates.

Why it matters: Roommates may have a harder time mingling their separate lives under one roof and seeing eye to eye on how to stay safe than people who live with families or significant others.

There's a striking partisan divide on coronavirus-related topics, reflecting the growing divide between reality as President Trump presents it and the reality presented by experts and health care workers.

Between the lines: Some of these issues aren't open to interpretation. We either have enough coronavirus tests to track outbreaks, or we don't. Health care workers have enough masks, or they don't.

New York City has cancelled all non-essential events during the month of June, Mayor Bill De Blasio announced on Monday.

Why it matters: The order will cancel iconic annual city events, like the Pride, Puerto Rican Day and Celebrate Israel parades. De Blasio said the city is working with event organizers to reschedule for later in the year.

• "We're going to miss all three of them in June, but they will be back," De Blasio said, adding, "We're going to do it when it's the right time."

Detroit Mayor Mike Duggan announced on Friday that the city will start making diagnostic tests available to all employees of “essential” businesses, and to city employees performing essential services.

Why it matters: It’s the first program of its kind, and a model for other cities to follow. And it’s a reminder that testing remains the limiting factor in every facet of our response to the coronavirus.

New York Gov. Andrew Cuomo announced on Thursday that he's stretching the state's stay-at-home order for another two weeks until May 15.

The big picture: Some governors across the U.S. have already lengthened their stay-at-home mandates past the White House's May 1 goal of reopening the economy. Public health experts have warned that lifting social distancing restrictions after 30 days would lead to a spike in infections this summer.
