A massive, year-long science expedition currently underway on an icebreaker in the Arctic Ocean is having to significantly alter its plans due to the Coronavirus pandemic.

After Bernie Sanders suffered three straight weeks of big losses across the country, the Vermont senator returned home to "assess his campaign."

The sun shines as Felix Quintana cruises through South Central Los Angeles. He's always been inspired by what he sees out of his car window, from the strip malls to the street vendors. "I love the hustle," he says. "The hand-painted signs, the swap meets, the people making money washing windshields."

But those moments can fly by. And his ongoing series of cyanotypes make us pause on the often overlooked Angelenos who work and live in the less glitzy, more gritty neighborhoods of LA County.

With coronavirus cases continuing to climb and hospitals facing the prospect of having to decide how to allocate limited staff and resources, the Department of Health and Human Services is reminding states and health care providers that civil rights laws still apply in a pandemic.

States are preparing for a situation when there's not enough care to go around by issuing "crisis of care" standards.

But disability groups are worried that those standards will allow rationing decisions that exclude the elderly or people with disabilities.

The World Health Organization says the virus that causes COVID-19 doesn't seem to linger in the air or be capable of spreading through the air over distances of more than about 3 feet.

But at least one expert in virus transmission said it's way too soon to know that.

Hippos can get hungry. Very hungry. So when zoos shut their doors to the public because of the coronavirus, zookeepers keep showing up to work to make sure everyone is fed.

Jenna Wingate feeds Fiona, the Cincinnati Zoo's 3-year-old, 1,300-pound hippo. Fiona was born premature, and Wingate has been looking after her since two hours after she was born.

Apple's new COVID-19 website and app allow users to screen themselves for coronavirus symptoms and receive recommendations from the Centers for Disease Control and Prevention on what to do next.

The tool was developed in partnership with the CDC, the White House's coronavirus task force and the Federal Emergency Management Agency. Both the website and the app were made publicly available on Friday.

The hospital ship USNS Comfort got underway from its pier in Norfolk, Va., on Saturday after a pomp-filled benediction by President Trump complete with a coterie of American flags and a military band.

The ship is scheduled to arrive in New York City on Monday to offer its roughly 1,000 hospital beds as surge capacity for the region hardest hit by the coronavirus disaster.

Patients without the disease can get treatment aboard the ship, the president said, freeing up treatment centers ashore for sufferers in the pandemic.

After broaching the possibility of quarantining New York, Connecticut and New Jersey, President Trump backtracked late Saturday, saying a "quarantine will not be necessary."

Earlier in the day, the president said he was "looking at" quarantining New York, New Jersey and parts of Connecticut because they had developed as "hot spots" of the coronavirus outbreak.

After a slow start, testing for COVID-19 has begun to ramp up in recent weeks. Giant commercial labs have jumped into the effort, drive-up testing sites have been established in some places, and new types of tests have been approved under emergency rules set by the Food and Drug Administration.

Former Oklahoma Sen. Tom Coburn, whose inflexible support of conservative policies placed him at the heart of many major congressional battles, has died at the age of 72. His former communications director, John Hart, confirmed that Coburn died Saturday morning "after a long battle with prostate cancer."

Coburn's former colleague, fellow Republican Sen. James Lankford of Oklahoma, remembered the senator as a "friend and a leader."

Comedian Marc Maron: We Need 'Groupthink Empathy' During COVID-19 Outbreak: "We [have] to do the right thing to protect those who are vulnerable," Maron says. His new Netflix stand-up special, End Times Fun, was named before the coronavirus pandemic.

As COVID-19 cases in the remote Pacific climb, it turns out that even natural isolation is no match against this pandemic.

The United States marked another grim milestone in its fight against the coronavirus on Saturday, when the number of deaths from the virus topped 2,000.

According to data from Johns Hopkins University, 2,010 Americans have now died from the coronavirus. The majority of deaths have been in New York City.

Let us all have a moment of sympathy – and perhaps even understanding — for Thomas Massie, Republican of Kentucky.

Massie was the guy who caught hell from all sides Friday when he tried to force a roll call vote on the coronavirus relief bill in the House of Representatives. He said he wanted every individual member to record his or her vote on the gargantuan $2 trillion package, which he called the biggest relief bill in the history of mankind.

In recent weeks doctors and nurses have reported dire shortages of protective gear; on the Cape Cod peninsula in Massachusetts, and in the San Francisco Bay Area, hospital workers say they're being forced to reuse N-95 masks. In New York, the current epicenter of the U.S.

The losses of the coronavirus pandemic became personal for many Americans this week. More people lost jobs. More people had to worry about their health. And more people died. These names are just a few among so many who gave something to our lives.

Joe Pinero's after-work routine has changed recently.

"I strip outside of my door, take basically all my clothes off and walk in naked and just get directly into a shower when I do come into the house," Pinero said.

But he doesn't think his neighbors in Hoboken, N.J., mind too much, because they know he works as an emergency room doctor.

"If anyone has seen me naked, I'm sorry. But it's probably gonna happen again," he said with a laugh.

Pan-fried buns with beef filling, shrimp stir-fried with seasonal bamboo shoots, roasted chicken and seared scallops — such dishes are on the menu for the Shanghai medical staff who recently returned from Wuhan in Hubei province, the epicenter of China's COVID-19 outbreak. To show its gratitude for the 1,649 now-quarantined workers, the city has cooked up a free 14-day meal plan for them.

The streets of downtown Laredo, Texas, are deserted. For decades, this dense retail district has catered to Mexican shoppers coming across the bridge from Nuevo Laredo. But these days, stores like Cindy's Electronics, Classic Perfumes, and Casa Raul Mens' Clothes are shuttered.

"Now our business has dropped 80 to 90%," says Natividad Dominguez, leaning on a glass case full of empanadas, turnovers and donuts at Pano's Bakery. "People would come across the bridge and pick up a donut. But no more. It's affecting us a lot."

Nestled in the mountains of eastern Australia are fragments of an ancient world. Damp, dark and lush, they are some of the oldest ecosystems on Earth: temperate rainforests that have persisted since the days of supercontinents and dinosaurs.

The Gondwana Rainforests of Australia — and the hundreds of rare species that call them home — are the ultimate survivors, clinging to wet, wild patches of a continent that's increasingly developed and dry.

But even these forests could not escape the country's unprecedented fire season unscathed.

The Reverend Joseph Lowery, co-founder of the Southern Christian Leadership Conference, died Friday, according to a statement by the Joseph & Evelyn Lowery Institute for Justice and Human Rights. He was 98 years old.

The statement said Lowery died peacefully at home Friday night, surrounded by his daughters.
