JUDY WOODRUFF: It’s been almost a month since Hurricane Maria destroyed much of Puerto Rico and killed at least 48 people. The island and its residents are still coming to grips with the scale of the devastation.

William Brangham brings us the latest.

WILLIAM BRANGHAM: Many Puerto Ricans are still in the dark, without electrical power. Hundreds of thousands still have no access to running water, and the rebuilding of the countless damaged homes, roads and facilities is just beginning.

The Associated Press reported yesterday that almost half the sewage treatment plants on the island are still out of service, increasing the risk of contamination and disease.

I’m joined now by David Begnaud. He’s a correspondent from CBS News who’s been doing some very strong reporting there from since when the storm hit, and is just back from his latest trip to the island.

David, welcome to the NewsHour.

I wonder. We saw many of your reports and others of people still three weeks out from the storm who are still drinking from streams and creeks. You heard — I mentioned this AP report about fears of contamination.

Can you just tell us what is going on there? How are people getting water now?

DAVID BEGNAUD, CBS News: Well, let me tell you this.

The governor of Puerto Rico said this morning that he’s aware of those reports and that they’re looking into it. What’s concerning, William, is that three weeks after the storm and at least a week after the allegations first surfaced that people might be trying to drink from toxic wells at what’s known as Superfund sites, the governor of Puerto Rico is still saying, we’re looking into it and telling people to stay out of rivers where sewage may be spilling into the river.

And, he said, we want them to stay away from the coastal areas.

How are people doing? They’re still desperate to get water. No one seems to be able to figure out how to get enough water to every single person on that island who needs it. And as long as people need water, it’s still an emergency phase.

Nearly four weeks later, no one seems to be able to move from the emergency to the recovery.

WILLIAM BRANGHAM: So, people who are — we see them drinking out of these PVC pipes that they have kind of rigged and sort of poked into the side of a creek.

People are just drinking that water straight, without purification, without boiling it; is that right?

DAVID BEGNAUD: Absolutely.

Look, they have got the PVC pipes tapped into the mountains so that it’s coming out of the stream that way. And they literally are — I saw a woman walk up to a potable water tank that the military had brought in, and she had a Clorox bottle.

And I said, “Ma’am, you’re putting drinkable water in a Clorox bottle?”

And she said, “It’s all I have got.”

Now, that was a good scenario. The other scenarios are people right now who are drinking from streams and creeks and rivers who have no water filters, who have nothing, right? They’re just taking this water.

Now, listen, the government got a million water-purifying tablets within the last week. It took almost three weeks to get those. Now there’s a large push to bring in water filters.

I have got to tell you, most of the water filters I’m seeing brought in are coming from the private sector, and civilian samaritans who are getting 1,000 or more from the mainland and flying them over to Puerto Rico and personally hand-delivering them.

WILLIAM BRANGHAM: That’s really incredible.

Medical facilities were another big — just a huge devastation on the island. I know you have been doing a lot of reporting on the USS Comfort.

DAVID BEGNAUD: Yes.

WILLIAM BRANGHAM: This is the huge Naval hospital that is now just offshore Puerto Rico.

But I understand it hasn’t been fully utilized. Can you tell us what your reporting has found there?

DAVID BEGNAUD: The two men running the ship told us that nearly 87 percent of the ship is empty. Sounds alarming, right? They have 200 beds, and 87 percent are empty.

Now, here’s what they said: We stand ready for whatever the government wants to do. We are waiting to be told by the government.

So, I went to the governor, and said exactly what’s happening. And he said: “Look, I’m not satisfied with what the protocol was from the beginning.”

He said, initially, they were prioritizing only the most critically ill patients go to the Comfort. And he said there was a layered process that was complicating things.

So, the governor, Ricardo Rossello, said: “I started to take out some of those layers, and I, said, listen, take people on the ship who may not be critically ill, but need good medical care and can’t get it at the hospital, where the lights are flickering and the A.C. is not running.”

That’s what the governor said.

Within a matter of hours, I got a tweet from a third-year medical student who said: “Let me tell you what a nightmare it has been to reach the Comfort.”

He said: “We have got a pediatric patient who desperately needs to get off this island, either to a hospital on the mainland or to the Comfort.”

And he said: “I went through Google and the local newspaper to find the number. I couldn’t find it.”

Now, here is how things work. Within about 30 minutes of that tweet going out and that medical student’s story being posted, the governor’s spokesperson responded with numbers that should be able to help.

The bottom line here, William, is that asking relentless questions and the good work of journalism is what’s making a difference there. It’s no one person. There’s no heroic work that’s being done by any journalist, other than people who are going back to the same officials and asking some of the same questions, relentlessly seeking the right answer that will make a difference.

WILLIAM BRANGHAM: One of the other pieces of reporting that you did that was very early in the story was this backlog of supplies trapped in container ships on the ports in Puerto Rico.

I understand some of that — some of those supplies are now moving. Can you tell us, are they getting to where they need to be throughout the island?

DAVID BEGNAUD: So, the shipping containers you’re talking about, about 3,000 sitting in the Port of San Juan, have been moved out, not all of them, but a majority of them.

And they were intended for grocery stores around the island. Right? So, those were private companies that had brought in these shipping containers, paid for the supplies, but couldn’t move them because their truck drivers were either at home, because the home had been destroyed, or the road was impassable.

More and more supplies are getting out. But let me tell you, the grocery stores around the island, they have a lot of nonperishables, Pringles, candy, cookies, all on the shelf.

But when you go to the meat section, it’s nearly 75 percent empty at the stores we have been to, the produce section 90 percent empty. And finding bottled water there is almost like playing a game.

WILLIAM BRANGHAM: David Begnaud, CBS News, thank you so much for your reporting. Thanks for your time.

DAVID BEGNAUD: You bet.

JUDY WOODRUFF: And in the day’s other news: A federal judge in Hawaii struck down the Trump administration’s latest travel ban.

That temporarily blocks enforcement of the order nationwide, but the Justice Department says it will appeal. The ban extended to six mostly Muslim nations, plus North Korea and Venezuela.

Pennsylvania Congressman Tom Marino withdrew today from consideration to be President Trump’s drug czar. That followed an investigation by The Washington Post and CBS News. They found Marino was key in passing a 2016 law that limits the Drug Enforcement Administration’s ability to rein in opioid distribution.

A new verbal battle has broken out between the president and Republican Senator John McCain. It began last night in Philadelphia, when the Arizona senator and former Vietnam POW appeared to criticize Mr. Trump and his followers. He cited a list of failings.

SEN. JOHN MCCAIN, R-Ariz.: To fear the world we have organized and led for three-quarters-of-a-century, to abandon the ideals we have advanced around the globe for the sake of some half-baked, spurious nationalism cooked up by people who would rather find scapegoats than solve problems.

(CHEERING AND APPLAUSE)

JUDY WOODRUFF: The president answered by saying, “At some point, I fight back, and it won’t be pretty.”

In turn, McCain said, “I have faced tougher adversaries.”

In Afghanistan, Taliban bombings and shootings left at least 74 people dead today. The worst was Paktika province in the east, where two car bombs killed dozens, including the provincial police chief, and wounded more than 100 others. Taliban militants also staged attacks in the south and west of the country.

In Syria, militia forces backed by the U.S. say they have retaken the Islamic State group’s de facto capital. The city of Raqqa had been under ISIS control since 2014. The battle to recapture it began in June. Today, Kurdish-led fighters celebrated as they moved into the city center. The U.S. military said 90 percent of Raqqa has been taken, with pockets of militants remaining.

There’s word that U.S. airstrikes in Yemen killed dozens of Islamic State fighters on Monday. The strikes were apparently carried out by drones. The Pentagon says the targets were training camps for recruits.

In Northern Iraq, Kurdish forces withdrew from more territory today, as Iraqi government troops advanced. It came on the heels of the Kurds’ vote for independence. Federal forces and allied militia had already forced the Kurds to leave the area in and around Kirkuk and its oil fields.

Iraq’s prime minister said that paves the way for talks.

HAIDER AL-ABADI, Prime Minister, Iraq (through interpreter): I call for dialogue on the basis of partnership in one country and under the Constitution. The referendum is finished and has become a thing from the past. We hoped that they would cancel it, but we have finished it on the ground.

JUDY WOODRUFF: Meanwhile, the president of Iraqi Kurdistan, Massoud Barzani, insisted that the referendum will not be in vain.

Another 10,000 to 15,000 Rohingya Muslims fled Buddhist Myanmar for Bangladesh over the weekend. Drone video showed snaking lines of refugees making the trek to already crowded camps. Many told of villages torched by mobs and soldiers. Others said they were starved out of their homes.

Back in this country, a new fire broke out in the San Francisco Bay Area, just as crews had made major progress against other fires in Northern California. Thick smoke billowed from the new site early today, as it burned through forests in the Santa Cruz Mountains. Weary fire crews said they’re calling in more help.

ROB SHERMAN, Division Chief, Cal Fire: So, the idea is to hit it pretty hard with aircraft and then go ahead and hit it with the ground resources at the same time. We have had north winds, a lot of drying, and everything’s really, really dry. So it’s challenging.

JUDY WOODRUFF: In Southern California, yet another fire spread on Mount Wilson, about 25 miles north of downtown Los Angeles. It threatened a historic observatory and communications towers.

President Trump’s overall wealth has taken a hit, as his New York real estate loses some of its luster. Forbes ranks him 248 this year on its list of the 400 wealthiest Americans. That’s down nearly 100 points from last year. His estimated worth is $3.1 billion.

Microsoft co-founder Bill Gates again tops the list. He’s worth nearly $90 billion.

And on Wall Street, the Dow Jones industrial average traded above 23,000 for the first time. In the end, it gained 40 points to close at 22997. The Nasdaq fell a fraction, and the S&P 500 added one point.

The post News Wrap: Trump’s latest travel ban blocked by federal judge appeared first on PBS NewsHour.

In America, there’s a significant kind of public insistence that one’s “freedom” is fundamentally tied to one’s wealth.

Much of the country views America through an aspirational and transformative lens, a colorblind and bias-free utopia, wherein wealth conveys equality and acts as a panacea for social and racial ills. Once an individual achieves massive financial success, or so the message goes, he or she will “transcend” the scourge of economic and racial inequality, truly becoming “free.”

Working in parallel with this reverence for this colorblind version of the “American Dream” is the belief that economic privilege mandates patriotic gratitude. Across industries and disciplines, Americans are told to love their nation uncritically, be thankful that they are exceptional enough to live in a country that allows citizens the opportunity to reach astronomical heights of economic prosperity.

For the nation’s black citizens, there’s often an additional racialized presumption lurking under the surface of these concepts: the notion that black success and wealth demands public silence on systemic issues of inequality and oppression.

These are durable and fragile ideologies that prop up the concept of the American Dream – durable because they are encoded in the very fabric of American culture (most Americans, including African Americans, have readily embraced these ideologies as assumed facts); yet fragile because it’s all too easy to see that one’s economic privilege is a lousy barrier against both individual and systemic discrimination and oppression.

Consequently, black people have also been among the most vocal challengers of these ideologies, as we’ve seen most recently with the Colin Kaepernick and the NFL #TakeAKnee demonstrations. In a show of solidary with the free agent quarterback, professional football players – the vast majority of whom are black – have been kneeling during the National Anthem as a means of protesting racial injustice and police brutality.

WATCH: NFL players team up in defiance and solidarity

Over the past few weeks, the president of the United States has brought renewed attention to the inherent tensions that define the ideologies of the “American Dream” through his repeated public criticisms of these kneeling NFL players.

“If a player wants the privilege of making millions of dollars in the NFL, or other leagues,” Trump recently tweeted, he or she should not be allowed to kneel. Labeling the protestors actions “disrespectful” to the country, flag and anthem, President Donald Trump has called for players to be fired, encouraged a boycott of the NFL, insisted that the league pass a rule mandating that players stand for the anthem and derided the protestors as “sons of bitches.”

In a dramatic ploy more befitting of a scripted reality television show, the president gloated that he had instructed Vice President Mike Pence to walk out of an Indianapolis Colts game the moment any player kneeled. This was an orchestrated show of power and outrage, designed to send a flamboyant political message given that Trump and Pence knew in advance that on that particular day, the Colts were playing the San Francisco 49ers – the team that currently has the most protestors. The NFL’s announcement this week that the league has no plans to penalize protesting players is the most recent event to provoke the president’s fury; taking to social media during the early morning, he once again equated kneeling with “total disrespect” for our country.

As many have pointed out, the president’s moralizing outrage toward the NFL players is selective and deeply flawed – his apparent patriotic loyalty hasn’t stopped the billionaire politician from criticizing the removal of Confederate statues, or attacking a Gold Star family, or mocking Sen. John McCain’s military service.

The NFL players and their defenders have repeatedly stated that the protests are intended to highlight racial inequality and oppression. They’ve also explained that their decision to kneel emerged from a desire to protest peacefully and respectfully after a sustained conversation with military veterans.

Trump has chosen to ignore these rationales and the structural issues of inequality that motivate the protests and instead, advance a narrative exclusively concerned with overt displays of American patriotism and the “privilege” of the NFL players. As one of president’s advisors explained, by aggressively targeting the NFL players, Trump believes that he is “winning the cultural war,” having made black “millionaire sport athletes his new [Hillary Clinton].”

READ MORE: As ‘America’s sport,’ the NFL cannot escape politics

It’s a cynical statement, revealing the president’s perception of the jingoism of his base of supporters who envision him as a crusader for American values and symbols.

In casting the black protestors as the antithesis of all of this, Trump has marked the players as unpatriotic elites and enemies of the nation. For a president who has consistently fumbled his way through domestic and foreign policy since he was elected, a culture war between “hard-working” and “virtuous” working-class and middle-class white Americans and rich, ungrateful black football players is a welcome public distraction.

Trump’s attacks on the NFL protestors are rooted in those competing tensions inherent to the American Dream: that wealth equals freedom; that economic privilege demands patriotic gratitude; and most importantly, that black people’s individual economic prosperity invalidates their concerns about systemic injustice and requires their silence on racial oppression.

Among the protestors’ detractors, this has become a common line of attack, a means of disparaging the black NFL players’ activism by pointing to their apparent wealth. The fact that systemic racism is demonstrably real and that individual prosperity does not make one immune to racial discrimination appears to be lost on the protestors’ critics.

Theirs is a grievance that suggests that black athletes should be grateful to live in this country; that racism can’t exist in America since black professional athletes are allowed to play and sign contracts for considerable sums of money; that black players owe the nation their silence since America “gave” them opportunity and access; that black athletes have no moral authority on issues of race and inequality because of their individual success; and that black athletes’ success was never theirs to earn, but instead, was given to them and can just as easily be taken away.

This culture war being waged over black athletes is not new. Black athletes – and entertainers – have long been hyper-aware of their peculiar place in American society as individuals beloved for their athletic and artistic talents, yet reviled the moment they use their public platform to protest systemic racial inequality. The parallels between the #TakeAKnee protests and the protests of Muhammad Ali or John Carlos and Tommie Smith are readily apparent; so too are there important similarities to the case of Paul Robeson.

An outspoken civil rights activist, collegiate and professional football player, lawyer, opera singer and actor, Robeson had his passport revoked in 1950 because of his political activism and speech – actions that all but destroyed his career. The star athlete and entertainer, “who had exemplified American upward mobility” quickly “became public enemy number one” as institutions cancelled his concerts, the public called for his death and anti-Robeson mobs burned effigies of him.

During a 1956 congressional hearing, the chairman of the House Committee on Un-American Activities beat a familiar refrain with Robeson, challenging the entertainer’s accusations of American racism and racial oppression. He saw no sign of prejudice, he argued, since Robeson was privileged, having gone to elite universities and playing collegiate and professional football.

READ MORE: Poll: Americans divided on NFL protests

Black athletes, even the silent ones, largely understand that their economic privilege doesn’t insulate them from the realities of racial discrimination. They also understand that their wealth and success is precarious and is often dependent not only upon their athletic performance, but also upon them remaining silent on issues of racial injustice, especially those that appear to question the “American Dream” or implicate the American public by association.

It should come as no surprise then that Colin Kaepernick, whose protests turned him into a national pariah despite his on-the-field talents, has filed a grievance against the NFL, accusing the league and its teams of blackballing him because of his political beliefs. “Principled and peaceful political protest,” Kaepernick’s lawyers argued in a statement, “should not be punished and athletes should not be denied employment based on partisan political provocation by the Executive Branch of our government.” Whether the ostracized Kaepernick will win his grievance is unknown, but it is certainly telling that he and his lawyers have rooted their claims in contested definitions of freedom and the precarious economic privilege of outspoken NFL players.

For the loudest and most vocal critics of black protestors, in particular, outspokenness is tantamount to treason, grounds for the harshest of punishments. Perhaps they would benefit from a close reading of James Baldwin, who once argued: “I love America more than any other country in this world, and, exactly for this reason, I insist on the right to criticize her perpetually.”

Imbuing robots with “human-level performance” in anything is an enormous challenge, but it’s worth it when you see a robot with the skill to interact with a human on a (nearly) human level. Google DeepMind has managed to achieve amateur human-level competence at table tennis, which is much harder than it looks, even for humans. Pannag Sanketi, a tech-lead manager in the robotics team at DeepMind, shared some interesting insights about performing the research. But first, video!

Some behind the scenes detail from Pannag:

• The robot had not seen any participants before. So we knew we had a cool agent, but we had no idea how it was going to fare in a full match with real humans. To witness it outmaneuver even some of the most advanced players was such a delightful moment for team!
• All the participants had a lot of fun playing against the robot, irrespective of who won the match. And all of them wanted to play more. Some of them said it will be great to have the robot as a playing partner. From the videos, you can even see how much fun the user study hosts sitting there (who are not authors on the paper) are having watching the games!
• Barney, who is a professional coach, was an advisor on the project, and our chief evaluator of robot’s skills the way he evaluates his students. He also got surprised by how the robot is always able to learn from the last few weeks’ sessions.
• We invested a lot in remote and automated 24x7 operations. So not the setup in this video, but there are other cells that we can run 24x7 with a ball thrower.
• We even tried robot-vs-robot, i.e. 2 robots playing against each other! :) The line between collaboration and competition becomes very interesting when they try to learn by playing with each other.

When we think of grasping robots, we think of manipulators of some sort on the ends of arms of some sort. Because of course we do—that’s how (most of us) are built, and that’s the mindset with which we have consequently optimized the world around us. But one of the great things about robots is that they don’t have to be constrained by our constraints, and at ICRA@40 in Rotterdam this week, we saw a novel new Thing: a robotic hand that can detach from its arm and then crawl around to grasp objects that would be otherwise out of reach, designed by roboticists from EPFL in Switzerland.

Fundamentally, robot hands and crawling robots share a lot of similarities, including a body along with some wiggly bits that stick out and do stuff. But most robotic hands are designed to grasp rather than crawl, and as far as I’m aware, no robotic hands have been designed to do both of those things at the same time. Since both capabilities are important, you don’t necessarily want to stick with a traditional grasping-focused hand design. The researchers employed a genetic algorithm and simulation to test a bunch of different configurations in order to optimize for the ability to hold things and to move.

You’ll notice that the fingers bend backwards as well as forwards, which effectively doubles the ways in which the hand (or, “Handcrawler”) can grasp objects. And it’s a little bit hard to tell from the video, but the Handcrawler attaches to the wrist using magnets for alignment along with a screw that extends to lock the hand into place.

The whole system is controlled manually in the video, but lead author Xiao Gao tells us that they already have an autonomous version (with external localization) working in the lab. In fact, they’ve managed to run an entire grasping sequence autonomously, with the Handcrawler detaching from the arm, crawling to a location the arm can’t reach, picking up an object, and then returning and reattaching itself to the arm again.
