Tesla Says Vehicle in Deadly Crash Was on Autopilot 

A vehicle in a fatal crash last week in California was operating on Autopilot, making it the latest accident to involve a self-driving vehicle, Tesla has confirmed.

The electric car maker said the driver, who was killed in the accident, did not have his hands on the steering wheel for six seconds before the crash, despite several warnings from the vehicle. Tesla Inc. tells drivers that its Autopilot system, which can maintain speed, change lanes and self-park, requires drivers to keep their eyes on the road and hands on the wheel in order to take control of the vehicle to avoid accidents. 

Tesla said its vehicle logs show the driver took no action to stop the Model X SUV from crashing into a concrete lane divider. Photographs of the SUV show that the front of the vehicle was demolished, its hood was ripped off  and its front wheels were scattered on the freeway.

The vehicle also caught fire, though Tesla said no one was in the vehicle when that happened. The company said the crash was made worse by a missing or damaged safety shield on the end of the freeway barrier that is supposed to reduce the impact into the concrete lane divider.

The crash happened in Mountain View, in California’s Silicon Valley. The driver was Walter Huang, 38, a software engineer for Apple.

“None of this changes how devastating an event like this is or how much we feel for our customer’s family and friends,” Tesla said on its website late Friday.

Earlier this month, a self-driving Volvo SUV being tested by ride-hailing service Uber struck and killed a pedestrian in Arizona.

Tesla Inc. defended its Autopilot feature, saying that while it doesn’t prevent all accidents, it makes them less likely to occur than is the case for vehicles without it.

Federal investigators are looking into last week’s crash, as well a separate crash in January of a Tesla Model S that may have been operating under the Autopilot system.

AP Analysis: Blacks Largely Missing From High-Salary Positions

Jonathan Garland’s fascination with architecture started early: He spent much of his childhood designing Lego houses and gazing at Boston buildings on rides with his father away from their largely minority neighborhood. 

But when Garland looked around at his architectural college, he didn’t see many who looked like him. There were few black faces among students, and fewer teaching skills or giving lectures. 

 

“If you do something simple like Google ‘architects’ and you go to the images tab, you’re primarily going to see white males,” said Garland, 35, who’s worked at Boston and New York architectural firms. “That’s the image, that’s the brand, that’s the look of an architect.”

And that’s not uncommon in other lucrative fields, 50 years after the Reverend Martin Luther King, a leader in the fight for equal employment opportunities, was assassinated.

An Associated Press analysis of government data has found that black workers are chronically underrepresented compared with whites in high-salary jobs in technology, business, life sciences and engineering, among other areas. Instead, many black workers find jobs in low-wage, less prestigious fields where they’re overrepresented, such as food service or preparation, building maintenance and office work, the AP analysis found.

‘Other America’

In one of his final speeches, King described the “Other America,” where unemployment and underemployment created a “fatigue of despair” for African-Americans. Despite economic progress for blacks in areas such as incomes and graduation rates, some experts say many African-Americans remain part of this “Other America,” with little hope of attaining top professional jobs, thanks to systemic yet subtle racism.

The AP analysis found that a white worker had a far better chance than a black one of holding a job in the 11 categories with the highest median annual salaries, as listed by the Bureau of Labor Statistics. The ratio of white-to-black workers is about 10-to-1 in management, 8-to-1 in computers and mathematics, 12-to-1 in law and 7-to-1 in education — compared with a ratio of 5.5 white workers for every black one in all jobs nationally. The top five high-salary fields have a median income range of $65,000 to $100,000, compared with $36,000 for all occupations nationwide.

In Boston, a hub for technology and innovation and home to prestigious universities, white workers outnumber black ones by about 27-to-1 in computer- and mathematics-related professions, compared with the overall ratio of 9.5-to-1 for workers in the city. Overall, Boston’s ratio of white-to-black workers is wider than that of the nation in six of the top 10 high-income fields.

Boston, where King had deep ties, earning his doctorate and meeting his wife, has a history of racial discord. Eight years after King’s assassination, at the height of turbulent school desegregation, a Pulitzer Prize-winning photograph from an anti-busing rally at City Hall showed a white man attacking a black bystander with an American flag.

The young victim was Theodore Landsmark. He’s now 71, a lawyer, an architect and director of Northeastern University’s Dukakis Center for Urban and Regional Policy.

Why progress lags

He said “structural discrimination” is the overarching cause of disproportionate race representation in high-salary fields. Landsmark and others say gains are elusive for myriad reasons: Substandard schools in low-income neighborhoods. White-dominated office cliques. Boardrooms that prefer familiarity to diversity. Discriminatory hiring practices. Companies that claim a lack of qualified candidates but have no programs to train minority talent.

Some also say investors are more likely to support white startups. When Rica Elysee, a lifelong Boston resident who grew up in predominantly black neighborhoods, brought her idea of an online platform linking beauty professionals with customers for in-home appointments to investors, she was shunned, she said.

“They said I didn’t belong in the program, that they couldn’t identify with it because they weren’t black,” said Elysee, 32, who initially marketed BeautyLynk to black women like herself. “I remember crying pretty harshly. They couldn’t relate to what I was doing.”

Some even advised her to move out of Boston, which had a booming innovation economy but was “not encouraging minorities in the tech space,” she said. Three years later, Elysee said BeautyLynk is slowly growing but still needs capital.

Most American metro areas are like Boston, with AP’s analysis showing that racial disparities in employment are indifferent to geography and politics. California’s Silicon Valley struggles to achieve diversity in computer fields. In Seattle, home to Amazon, whites outnumber blacks nearly 28-to-1 in computer- and math-related fields. Financial powerhouse New York has a 3-to-1 ratio of white-to-black workers in all occupations, but nearly 6-to-1 in business and finance. Hollywood shows inequality in entertainment, with almost nine whites for every black worker.

In Atlanta, King’s hometown, the proportional representation of black-to-white workers is close to even in many fields. Many reasons are cited. Atlanta has historically black colleges and universities such as King’s alma mater, Morehouse; the first black mayor, Maynard Jackson, pressed for policies helping black professionals after his 1973 election; and events like the 1996 Olympics opened doors for entrepreneurs of all races.

Nationally, it’s much different

Atlanta is an exception. For nearly all of the past half-century, black unemployment nationally has hovered at about twice that of whites.

President Donald Trump touted on Twitter that December’s 6.8 percent unemployment rate for blacks was the lowest in 45 years — a number critics say ignores a greater reality. For example, in an economy that increasingly demands advanced degrees, Department of Education data show that black representation among graduates in science, tech, engineering and mathematics peaked at 9.9 percent in 2010 and has been slowly declining.

In Boston, Democratic Mayor Marty Walsh said in a recent speech that the city is addressing the issue and is committed to placing 20,000 low-income residents in “good-paying jobs” by 2022.

Landsmark said stronger role models may be a solution. As Boston Architectural College’s president, he mentored Garland. They discussed race issues in the professional world — as when Garland, trying to land jobs in his neighborhood, realized many people who looked like him were unfamiliar with the very concept of architecture. He once had to explain to a homeowner who wanted his roof reframed: “I’m not a builder, I’m an architect.”

Today, Garland speaks at high schools and works at the DREAM Collaborative, which focuses on projects in low-income neighborhoods.

“I know the barriers exist in other folks’ minds, and I have to disprove that,” he said. “I keep myself focused on the issues.”

Scientists Track Chinese Space Station’s Final Hours in Orbit

Scientists are monitoring a defunct Chinese space station that is expected to fall to Earth sometime this weekend — the largest man-made object to re-enter Earth’s atmosphere in a decade.

The head of the European Space Agency’s debris office, Holger Krag, says China’s Tiangong-1 space station likely will fall to Earth Sunday.

Krag said it still not yet known where the space station will hit Earth, but said it would be extremely unlikely for anyone to be injured when it does.

“Our experience is that for such large objects typically between 20 and 40 percent of the original mass, of 8.5 tons, will survive re-entry and then could be found on the ground, theoretically,” he said.

“However, to be injured by one of these fragments is extremely unlikely. My estimate is that the probability to be injured by one of these fragments is similar to the probability of being hit by lightning twice in the same year,” Krag added.

China’s first space lab, Tiangong-1 — or “Heavenly Palace 1″ — was launched in 2011 as a facility for testing docking capabilities with other Chinese spacecraft and to explore the possibilities for building a larger permanent space station by 2023.

Chinese astronauts visited it several times flying aboard the Shenzhou spacecraft.

It was scheduled for a controlled de-orbit and eventual crash into the Pacific Ocean, but in September 2016 China’s space agency conceded it had lost contact with the station.

Krag, says the 8-and-a-half ton craft will re-enter the atmosphere at a speed of 27,000 kilometers per hour.

He said the space station is expected to fall between the areas of 43 degrees south and 43 degrees north, and everything outside that zone is considered safe.

“Northern Europe including France, Germany, Austria and Switzerland are definitely on the safe side. Southern Europe, the southern part of North America, South Asia, Africa, Australia and also South America are still within the zone today,” he said.

The re-entry area covers huge parts of the Earth’s oceans, so any surviving pieces of the space station are most likely to end up at the bottom of the sea.

 

Australian Project to Probe Links Between Head Injuries in Sport, Disease

Researchers in Australia have begun an ambitious task to learn more about the long-term impacts of head injuries suffered by athletes. This week, the Australian Sports Brain Bank was launched in Sydney, and experts are encouraging players who have participated in all levels of sport – whether or not they’ve had a head injury – to donate their brains to the cause after they die.

The Brain Bank has been set up to investigate links between concussion, head injuries and Chronic Traumatic Encephalopathy, or CTE.  It is a neurodegenerative disease found in people with a history of repetitive brain trauma.

The Australian study is being supported by American researchers, who set up a similar brain bank a decade ago.

Dr. Chris Nowinski, head of the Boston-based Concussion Legacy Foundation which has examined the brains of deceased National Football League players, says the presence of CTE among them is pervasive.

“Any contact sport where you receive repetitive brain trauma puts you at risk for this disease.  We do not know at what risk but we have seen CTE in 110 of the first 111 players that we have studied, which has really surprised us.”

Nowinski believes energy from blows to the head during competition causes brain tissue to move.  Symptoms of CTE include depression, aggression and memory loss, and can take years or decades to appear.

The cause of CTE has yet to be established, but the disease has prompted a class action lawsuit in the U.S.

Australia’s Brain Bank is a joint venture between Sydney University and the city’s Royal Prince Alfred Hospital.  It hopes to obtain 500 brains over the next 10 years.

 

Helping the Planet, One Burger at a Time

Chef Rob Morasco didn’t set out to make a planet-friendly burger.

But the 25 percent mushroom burger he created at food service company Sodexo not only has a lower carbon footprint, it’s also lower in calories, fat and salt.

It’s juicier, too.

“When you bite into it, it’s kind of like a flavor explosion,” Morasco said. “And you don’t taste the mushrooms, either.”

And because mushrooms are cheaper than beef, he could answer customer demand for antibiotic- and hormone-free burgers “without having to jack up the price,” he said.

Mushroom-blended burgers have been catching on among both chefs and environmentalists. In March, Sonic Drive-In became the first fast-food chain to offer them.

WATCH: These Burgers Are Better for the Planet, but You’d Never Know It

​2 million cars

Americans eat about 10 billion hamburgers each year, according to the World Resources Institute (WRI).

All those burgers take a toll on the planet.

Beef is “the most resource-intensive food that we commonly eat,” Richard Waite of WRI said.

Beef accounts for about half the greenhouse gases produced by the American diet, he added. Cows take far more feed, land and water than any other source of protein.

If every burger in America were blended with mushrooms, WRI estimates the greenhouse-gas savings would be like taking more than 2 million cars off the road.

It would save as much water as nearly 3 million American households use in a year. And it would reduce the demand for farmland by an area larger than the state of Maryland.

For the carnivore

Blended burgers are part of The Culinary Institute of America and Harvard T.H. Chan School of Public Health’s Menus of Change project, challenging chefs across the food industry to make their meals healthier and more sustainable.

Demand for meatless meals is growing along with rising health and environmental concerns. There are bean burgers, soy burgers, even beet-infused veggie burgers that “bleed.”

But it’s a limited market.

“The veggie burgers tend to cater to folks who identify as vegetarian or vegan, or actively want to be eating less meat,” Waite said.

On the other hand, blended burgers appeal to “the real carnivores, someone who really loves meat,” he added. “This is potentially a dish that could have broad mainstream appeal and also pretty big environmental benefits.”

Helps keep burgers juicy

Chefs say the mushrooms retain water, helping the burger stay juicy as it cooks.

Sonic Drive-In’s ads for its new Signature Slinger blended burger play up the juiciness and the lower calories.

“When you’re about something that is going to be better for you, it had better deliver the flavor first,” said Scott Uehlein, vice president for product innovation and development at Sonic Drive-In.

The company is piloting the burgers in a two-month trial run.

And the potential goes beyond burgers.

About 400 cafeterias, universities and hospitals are using Sodexo’s blended beef to prepare not only burgers, but lasagna, chili, meatballs, meatloaf and more. The company has adapted 30 popular recipes to use its mushroom blend.

“All those different things you can make with that product just like you would make with regular ground beef,” chef Morasco said.

These Burgers Are Better for the Planet, but You’d Never Know It

As the world’s population heads toward 10 billion by midcentury, experts are wrestling with how to feed the world without wrecking the planet. It’s not easy to find foods with lower environmental impact that still taste as good as the ones they are intended to replace. But chefs and environmentalists are both cheering one new menu item: the mushroom-blended burger. VOA’s Steve Baragona has more.

Adrift Chinese Space Station Re-Entry Expected Sunday

Space scientists keeping track of dysfunctional space equipment are closely monitoring the expected re-entry of the largest piece of space junk so far. The Chinese space station Tiangong 1 will re-enter the atmosphere Sunday, but experts say it will be traveling so fast that the resulting friction will cause it to disintegrate and burn. But as VOA’s George Putic reports, small pieces may still reach the Earth.

Kids, Candymakers Look Forward to Easter Holiday

The Easter holiday is synonymous with symbols of spring, and for kids, it means candy in their Easter baskets. From Washington, VOA’s Jill Craig finds out how much sales increase over the holiday, and what the best sellers are.

Traditional Pakistani Bamboo Curtains Gaining Popularity

Traditional handicrafts from Pakistan are exported to many countries around the world. One item that appears to be gaining in popularity are the country’s hand-made bamboo curtains. VOA’s Saman Khan has more in this report from Lahore, Pakistan, narrated by Sarah Zaman.

NY’s Immigrant Taxi Drivers Despair as Taxi Industry Slumps

A financially distraught yellow cab driver from Romania recently hanged himself in his New York garage, marking the fourth suicide among city taxi drivers in as many months. In the tragedy’s aftermath, members of New York’s taxicab drivers union are renewing their calls for a cap on the number of app-based for-hire vehicles, such as Uber and Lyft, which they say are driving workers of a once-thriving industry into the ground. VOA’s Ramon Taylor reports.

Could Enemies Target Undersea Cables That Link the World?

Russian ships are skulking around underwater communications cables, causing the U.S. and its allies to worry the Kremlin might be taking information warfare to new depths.

Is Moscow interested in cutting or tapping the cables? Does it want the West to worry it might? Is there a more innocent explanation? Unsurprisingly, Russia isn’t saying.

But whatever Moscow’s intentions, U.S. and Western officials are increasingly troubled by their rival’s interest in the 400 fiber-optic cables that carry most of world’s calls, emails and texts, as well as $10 trillion worth of daily financial transactions.

“We’ve seen activity in the Russian navy, and particularly undersea in their submarine activity, that we haven’t seen since the ’80s,” General Curtis Scaparrotti, commander of the U.S. European Command, told Congress this month.

Without undersea cables, a bank in Asian countries couldn’t send money to Saudi Arabia to pay for oil. U.S. military leaders would struggle to communicate with troops fighting extremists in Afghanistan and the Middle East. A student in Europe wouldn’t be able to Skype his parents in the United States.

Small passageways

All this information is transmitted along tiny glass fibers encased in undersea cables that, in some cases, are little bigger than a garden hose. All told, there are 620,000 miles of fiber-optic cable running under the sea, enough to loop around Earth nearly 25 times.

Most lines are owned by private telecommunications companies, including giants like Google and Microsoft. Their locations are easily identified on public maps, with swirling lines that look like spaghetti. While cutting one cable might have limited impact, severing several simultaneously or at choke points could cause a major outage.

The Russians “are doing their homework and, in the event of a crisis or conflict with them, they might do rotten things to us,” said Michael Kofman, a Russian military expert at nonprofit research group CNA Corp.

It’s not Moscow’s warships and submarines that are making NATO and U.S. officials uneasy. It’s Russia’s Main Directorate of Deep Sea Research, whose specialized surface ships, submarines, underwater drones and minisubs conduct reconnaissance, underwater salvage and other work.

One ship run by the directorate is the Yantar. It’s a modest, 354-foot oceanographic vessel that holds a crew of about 60. It most recently was off South America’s coast helping Argentina search for a lost submarine.

Parlamentskaya Gazeta, the Russian parliament’s publication, last October said the Yantar has equipment “designed for deep-sea tracking” and “connecting to top-secret communication cables.” The publication said that in September 2015, the Yantar was near Kings Bay, Georgia, home to a U.S. submarine base, “collecting information about the equipment on American submarines, including underwater sensors and the unified [U.S. military] information network.” Rossiya, a Russian state TV network, has said the Yantar not only can connect to top-secret cables but also can cut them and “jam underwater sensors with a special system.”

Russia’s Defense Ministry did not respond to a request for comment.

Preparing for sabotage

There is no hard evidence that the ship is engaged in nefarious activity, said Steffan Watkins, an information technology security consultant in Canada tracking the ship. But he wonders what the ship is doing when it’s stopped over critical cables or when its Automatic Identification System tracking transponder isn’t on.

Of the Yantar’s crew, he said: “I don’t think these are the actual guys who are doing any sabotage. I think they’re laying the groundwork for future operations.”

Members of Congress are wondering, too. 

Representative Joe Courtney, a Connecticut Democrat on a House subcommittee on sea power, said of the Russians, “The mere fact that they are clearly tracking the cables and prowling around the cables shows that they are doing something.”

Democratic Senator Gary Peters of Michigan, an Armed Services Committee member, said Moscow’s goal appears to be to “disrupt the normal channels of communication and create an environment of misinformation and distrust.”

The Yantar’s movements have previously raised eyebrows.

On October 18, 2016, a Syrian telecom company ordered emergency maintenance to repair a cable in the Mediterranean that provides internet connectivity to several countries, including Syria, Libya and Lebanon. The Yantar arrived in the area the day before the four-day maintenance began. It left two days before the maintenance ended. It’s unknown what work it did while there.

Watkins described another episode on November 5, 2016, when a submarine cable linking Persian Gulf nations experienced outages in Iran. Hours later, the Yantar left Oman and headed to an area about 60 miles west of the Iranian port city of Bushehr, where the cable runs ashore. Connectivity was restored just hours before the Yantar arrived on November 9. The boat stayed stationary over the site for several more days.

Undersea cables have been targets before.

At the beginning of World War I, Britain cut a handful of German underwater communications cables and tapped the rerouted traffic for intelligence. In the Cold War, the U.S. Navy sent American divers deep into the Sea of Okhotsk off the Russian coast to install a device to record Soviet communications, hoping to learn more about the U.S.S.R.’s submarine-launched nuclear capability.

Eavesdropping by spies

More recently, British and American intelligence agencies have eavesdropped on fiber-optic cables, according to documents released by Edward Snowden, a former National Security Agency contractor.

In 2007, Vietnamese authorities confiscated ships carrying miles of fiber-optic cable that thieves salvaged from the sea for profit. The heist disrupted service for several months. And in 2013, Egyptian officials arrested three scuba divers off Alexandria for attempting to cut a cable stretching from France to Singapore. Five years on, questions remain about the attack on a cable responsible for about a third of all internet traffic between Egypt and Europe.

Despite the relatively few publicly known incidents of sabotage, most outages are due to accidents.

Two hundred or so cable-related outages take place each year. Most occur when ship anchors snap cables or commercial fishing equipment snags the lines. Others break during tsunamis, earthquakes and other natural disasters.

But even accidental cuts can harm U.S. military operations. 

In 2008 in Iraq, unmanned U.S. surveillance flights nearly screeched to a halt one day at Balad Air Base, not because of enemy mortar attacks or dusty winds. An anchor had snagged a cable hundreds of miles away from the base, situated in the “Sunni Triangle” northwest of Baghdad.

The severed cable had linked controllers based in the United States with unmanned aircraft flying intelligence, surveillance and reconnaissance missions for coalition forces in the skies over Iraq, said retired Air Force Colonel Dave Lujan of Hampton, Virginia.

“Say you’re operating a remote-controlled car and all of a sudden you can’t control it,” said Lujan, who was deputy commander of the 332nd Expeditionary Operations Group at the base when the little-publicized outage lasted for two to three days. “That’s a big impact,” he said, describing how U.S. pilots had to fly the missions instead.

Trump EPA Expected to Roll Back Auto Gas Mileage Standards 

The Trump administration is expected to announce that it will roll back automobile gas mileage and pollution standards that were a pillar in the Obama administration’s plans to combat climate change. 

It’s not clear whether the announcement will include a specific number, but current regulations from the Environmental Protection Agency require the fleet of new vehicles to get 36 miles per gallon in real-world driving by 2025. That’s about 10 mpg over the existing standard. 

Environmental groups, who predict increased greenhouse gas emissions and more gasoline consumption if the standards are relaxed, say the announcement could come Tuesday at a Virginia car dealership. EPA spokeswoman Liz Bowman said in an email Friday that the standards are still being reviewed.

Legal showdown

Any change is likely to set up a lengthy legal showdown with California, which currently has the power to set its own pollution and gas mileage standards and doesn’t want them to change. About a dozen other states follow California’s rules, and together they account for more than one-third of the vehicles sold in the US. Currently the federal and California standards are the same. 

Automakers have lobbied to revisit the requirements, saying they’ll have trouble reaching them because people are buying bigger vehicles due to low gas prices. They say the standards will cost the industry billions of dollars and raise vehicle prices due to the cost of developing technology needed to raise mileage. 

When the standards were first proposed, the government predicted that two-thirds of new vehicles sold would be cars, with the rest trucks and SUVs, said Gloria Bergquist, spokeswoman for the Alliance of Automobile Manufacturers. Now the reverse is true, she said.

Still, environmental groups say the standards save money at the pump, and the technology is available for the industry to comply. 

Health risk

They also say burning more gasoline will put people’s health at risk. 

“The American public overwhelmingly supports strong vehicle standards because they cut the cost of driving, reduce air pollution, and combat climate change,” said Luke Tonachel, director of the Natural Resources Defense Council’s Clean Vehicles and Fuels Project. 

The EPA and the National Highway Traffic Safety Administration are involved in setting the standards, which would cover the years 2022 through 2025. 

Some conservative groups are pressing EPA Administrator Scott Pruitt to revoke a waiver that allows California to set its own rules. They say California shouldn’t be allowed to set policy for the rest of the nation. Pruitt has publicly questioned the veracity of evidence complied by climate scientists, including those in his own agency, that global warming is overwhelmingly caused by man-made carbon emissions from burning fossil fuels.

If the waiver is revoked, California Attorney General Xavier Becerra says the state will resist. “What we’re doing to protect California’s environment isn’t just good for our communities — it’s good for the country,” he said in a statement. “We’re not looking to pick a fight with the Trump administration, but when they threaten our values, we’re ready.” 

Huge dilemma

Getting rid of the waiver or having two gas mileage and pollution requirements presents a huge dilemma for automakers: while they would like to avoid fines for failing to meet the standards, they also want the expense of building two versions of cars and trucks, one for the California-led states and another for the rest of the country.

Mark Reuss, a General Motors’ product development chief, said in a recent interview that he would rather have a single nationwide standard, even if it stays the same. He called two standards “just waste,” because they would require different vehicle equipment and costly additional engineering. “I want one good one,” he said. “I could focus all my engineers on one.”

Automakers agreed to the standards in 2012, but lobbied for and received a midterm review in 2018 to account for changes in market conditions. In the waning days of the Obama presidency, the EPA did the review and proclaimed that the standards have enough flexibility and the technology is available to meet them.

Changes would be years away

Janet McCabe, who was acting assistant EPA administrator under Obama when the review was done, said Friday it will take a couple years for the EPA to propose new rules, gather public comment and finalize any changes. Any rollback would likely bring legal challenges, forcing Pruitt’s EPA to defend the science behind the changes. 

“This would all take a long time,” said McCabe, now a senior fellow at the Environmental Law and Policy Center.

In the meantime, automakers have to proceed with plans for new cars and trucks under the current gas mileage requirements because it takes years to develop vehicles.

Facebook ‘Ugly Truth’ Memo Triggers New Firestorm Over Ethics

Was a leaked internal Facebook memo aimed at justifying the social network’s growth-at-any-cost strategy? Or simply a way to open debate on difficult questions over new technologies?

The extraordinarily blunt memo by a high-ranking executive — leaked this week and quickly repudiated by the author and by Facebook — warned that the social network’s goal of connecting the world might have negative consequences, but that these were outweighed by the positives.

“Maybe it costs a life by exposing someone to bullies,” the 2016 memo by top executive Andrew “Boz” Bosworth said. “Maybe someone dies in a terrorist attack coordinated on our tools.”

While Bosworth and Facebook chief Mark Zuckerberg said the memo was only a way to provoke debate, it created a new firestorm for the social network mired in controversy over the hijacking of personal data by a political consulting firm linked to Donald Trump.

David Carroll, a professor of media design at the New School Parsons, tweeted that the memo highlighted a “reckless hubristic attitude” by the world’s biggest social network.

“What is so striking is that an executive chose to have this conversation on a Facebook wall,” said Jennifer Grygiel, a Syracuse University professor who studies social networks. “He showed poor judgment and poor business communication skills. It speaks to Facebook’s culture.”

Grygiel said these kinds of issues require “thoughtful discussion” and should take place within a context of protecting users. “When these companies build new products and services, their job is to evaluate the risks, and not just know about them, but ensure public safety.”

Bosworth, considered part of chief executive Zuckerberg’s inner circle, wrote: “The ugly truth is that we believe in connecting people so deeply that anything that allows us to connect more people more often is ‘de facto’ good.”

On Thursday, he said he merely wanted to open a discussion and added that “I don’t agree with the post today and I didn’t agree with it even when I wrote it.”

Zuckerberg responded that he and many others at Facebook “strongly disagreed” with the points raised.

‘Offloading’ ethical questions

Jim Malazita, a professor of science and technology studies at Rensselaer Polytechnic Institute, said it was not surprising to see the memo in an industry whose work culture is highly compartmentalized.

Malazita said the memo frames the discussion with the assumption that technology and connecting people is always positive.

“By the assumptions built into that framework they are already shutting down a whole bunch of conversations,” he said.

Malazita added that most people who learn computer science are taught to make these technologies work as well as possible, while “offloading” the question of moral responsibility.

“It’s not that they don’t care, but even when they care about the social impact, there’s a limit to how much they practice that care.”

Joshua Benton, director of Harvard University’s Nieman Journalism Lab, said it may be too easy to blame Facebook for misuse of the platform.

“I’m rarely in a position to defend Facebook,” he said, but the view that a technology is worth spreading even though some people will use it for terrible ends “is something you could have believed about the telegraph, the telephone, email, SMS, the iPhone, etc,” Benton tweeted.

Doing the right thing

Patrick Lin, director of the ethics and emerging sciences group at California Polytechnic State University, said he sees “no evidence that Facebook’s culture is unethical, though just one senior executive in the right place can poison the well.”

“I’d guess that most Facebook employees want to do the right thing and are increasingly uncomfortable with how the proverbial sausage is made,” Lin added.

Copies of internal responses at Facebook published by The Verge website showed many employees were angry or upset over the Bosworth memo but that some defended the executive.

Others said the leaks may suggest Facebook is being targeted by spies or “bad actors” trying to embarrass the company.

People With Sinus Infections Stay on Antibiotics Too Long, Study Indicates

Most people prescribed antibiotics for sinus infections are on treatment courses of 10 days or longer even though infectious-disease doctors recommend five to seven days for uncomplicated cases, a U.S. study suggests.

Researchers examined data from a sample representing an estimated 3.7 million adults treated for sinusitis and prescribed antibiotics in 2016. Overall, 70 percent of antibiotics prescribed were for 10 days or longer, the study found.

“Anytime antibiotics are used, they can cause side effects and lead to antibiotic resistance,” said senior study author Dr. Katherine Fleming-Dutra, deputy director of the Office of Antibiotic Stewardship at the U.S. Centers for Disease Control and Prevention in Atlanta.

“This is why it is so important to only use antibiotics when they are needed and to use the right antibiotic for the minimum effective duration,” Fleming-Dutra said by email.

Common side effects of antibiotics can include rash, dizziness, nausea, diarrhea and yeast infections, she said. More serious side effects may include life-threatening allergic reactions and Clostridium difficile infection, which causes diarrhea that can lead to severe colon damage and death.

Antibiotic resistance occurs when bacteria develop the ability to defeat the drugs designed to kill them and can make infections harder to treat.

​Relatively new guidelines

When antibiotics are prescribed for sinus infections, only five to seven days of therapy are needed for uncomplicated cases, when patients start to recover within a few days of starting treatment and if they don’t have signs that the infection has spread beyond the sinuses, according to the Infectious Diseases Society of America (IDSA).

These guidelines are relatively new, however, and it’s possible some of the longer courses of antibiotics prescribed in the study occurred because not all doctors have absorbed the new practice recommendations, Fleming-Dutra said. Prior to 2012, the IDSA recommended 10 to 14 days of antibiotics for sinus infections in adults.

In the study, no penicillin or tetracycline prescriptions were for five-day courses and only 5 percent of prescriptions were for seven-day courses of penicillins, tetracyclines or fluoroquinolones.

When researchers excluded azithromycin, an antibiotic that’s not recommended for sinus infections, they found that 91 percent of all antibiotic courses prescribed for sinus infections were for 10 days or longer.

The study didn’t examine whether or how the duration of antibiotics prescriptions affected treatment of sinus infections or the potential for side effects.

Researchers also focused only on acute sinus infections, and by excluding some cases where the type of infection was unclear, they may have left out some acute cases, the study team noted in AMA Internal Medicine.

It’s also possible that in some cases, doctors prescribed antibiotics for 10 days or longer and instructed patients to stop after five to seven days unless they were still experiencing symptoms, said Dr. Sharon Meropol, a researcher at Case Western Reserve University School of Medicine in Cleveland, Ohio, who wasn’t involved in the study.

Medicine switch

One pitfall in this approach is that when patients improve slowly, it’s possible they’re infected with organisms that are resistant to the antibiotic prescribed, and that they would recover faster if they switched to a different antibiotic

instead of continuing the current one longer, Meropol said by email.

“Older .. acute bacterial sinusitis guidelines were written with the belief that if antibiotics were taken for shorter durations of time, that the bacteria would not be completely eradicated and that would risk persistent, recurrent

and antibiotic-resistant infections,” Meropol said.

“But the recommendations have changed on this because subsequent studies have shown the opposite is true — that in fact if the patient is responding to treatment, five to seven days is safe and is usually enough,” Meropol added. “A longer treatment is not usually needed.”

Science: What We Know About Cancer Risk and Coffee

Trouble is brewing for coffee lovers in California, where a judge ruled that sellers must post scary warnings about cancer risks. But how frightened should we be of a daily cup of joe? Not very, some scientists and available evidence seem to suggest.

Scientific concerns about coffee have eased in recent years, and many studies even suggest it can help health.

“At the minimum, coffee is neutral. If anything, there is fairly good evidence of the benefit of coffee on cancer,” said Dr. Edward Giovannucci, a nutrition expert at the Harvard School of Public Health.

The World Health Organization’s cancer agency moved coffee off the “possible carcinogen” list two years ago, though it says evidence is insufficient to rule out any possible role.

The current flap isn’t about coffee itself, but a chemical called acrylamide that’s made when the beans are roasted. Government agencies call it a probable or likely carcinogen, based on animal research, and a group sued to require coffee sellers to warn of that under a California law passed by voters in 1986.

The problem: No one knows what levels are safe or risky for people. The U.S. Environmental Protection Agency sets acrylamide limits for drinking water, but there aren’t any for food.

“A cup of coffee a day, exposure probably is not that high,” and probably should not change your habit, said Dr. Bruce Y. Lee of Johns Hopkins Bloomberg School of Public Health. “If you drink a lot of cups a day, this is one of the reasons you might consider cutting that down.”

Here’s what’s known about the risks.

 

The chemical

Start with the biggest known risk factor for cancer — smoking — which generates acrylamide. In the diet, French fries, potato chips, crackers, cookies, cereal and other high-carbohydrate foods contain it as a byproduct of roasting, baking, toasting or frying.

Food and Drug Administration tests of acrylamide levels found they ranged from 175 to 351 parts per billion (a measure of concentration for a contaminant) for six brands of coffee tested; the highest was for one type of decaf coffee crystals. By comparison, French fries at one fast-food chain ranged from 117 to 313 parts per billion, depending on the location tested. Some commercial fries had more than 1,000.

Even some baby foods contain acrylamide, such as teething biscuits and crackers. One brand of organic sweet potatoes tested as having 121 parts per billion.

What’s the risk?

The “probable” or “likely” carcinogen label is based on studies of animals given high levels of acrylamide in drinking water. But people and rodents absorb the chemical at different rates and metabolize it differently, so its relevance to human health is unknown.

A group of 23 scientists convened by the WHO’s cancer agency in 2016 looked at coffee — not acrylamide directly — and decided coffee was unlikely to cause breast, prostate or pancreatic cancer, and that it seemed to lower the risks for liver and uterine cancers. Evidence was inadequate to determine its effect on dozens of other cancer types.

The California law

Since 1986, businesses have been required to post warnings about chemicals known to cause cancer or other health risks — more than 900 substances are on the state’s list today — but what’s a “significant” risk is arguable.

Coffee sellers and other defendants in the lawsuit that spurred Thursday’s ruling have a couple of weeks to challenge it or appeal.

The law “has potential to do much more harm than good to public health,” by confusing people into thinking risks from something like coffee are similar to those from smoking, Giovannucci said.

The International Food Information Council and Foundation, an organization funded mostly by the food and beverage industry, says the law is confusing the public because it doesn’t note levels of risk, and adds that U.S. dietary guidelines say up to five cups of coffee a day can be part of a healthy diet.

Dr. Otis Brawley, the American Cancer Society’s chief medical officer, said, “The issue here is dose, and the amount of acrylamide that would be included in coffee, which is really very small, compared to the amount from smoking tobacco. I don’t think we should be worried about a cup of coffee.”

Amy Trenton-Dietz, public health specialist at the University of Wisconsin-Madison, said the California ruling contrasts with what science shows.

“Studies in humans suggest that, if anything, coffee is protective for some types of cancer,” she said. “As long as people are not putting a lot of sugar or sweeteners in, coffee, tea and water are the best things for people to be drinking.”

In Philippines, Devotees Re-Enact Good Friday Crucifixions

Filipino Roman Catholic devotees, including a woman, were nailed to wooden crosses in a gory Good Friday re-enactment of Jesus Christ’s sufferings that was watched by thousands of spectators but frowned upon by church leaders.

At least three of eight devotees wearing crowns of twigs were crucified by midafternoon by villagers north of Manila who were dressed as Roman centurions.

The spectacle in San Pedro Cutud village reflects a unique brand of Catholicism that merges church traditions with folk superstitions. Many of the mostly impoverished penitents undergo the ritual to atone for sins, pray for the sick or a better life, or give thanks for what they believe were God-given miracles.

Church discourages ritual

The Lenten rituals are frowned upon by church leaders in the Philippines, Asia’s largest Roman Catholic nation, especially if the event is used to boost tourism and business. The re-enactments of the crucifixion, however, have persisted and became an awaited tourist attraction in the largely unknown village in Pampanga province, about 80 kilometers (50 miles) north of the capital.

While the crucifixions have become a summer tradition to locals, they still leave many foreign tourists bewildered.

“It’s terrible,” Luke Henkel from Florida said. “You wanna stop it.”

Mayor Edwin Santiago of San Fernando, the city where San Pedro Cutud lies, said more than 400 police officers were deployed and first-aid stations set up to look after the huge crowds.

“We provide assistance because we can’t stop the influx of tourists,” Pangilinan said. “We don’t promote it as a festival but it’s rather a show of respect to a local tradition.”

Tourists and commerce

Villagers used the crowd-drawing events to peddle food, water, fans, umbrellas and souvenirs and rent out parking slots and toilets. A leading cellphone company provided tents for shade with its name embossed on them.

Archbishop Socrates Villegas said it’s best for Catholics to mark Lent in prayers and acts of love and charity.

“Instead of spilling your blood on the streets, why not walk into a Red Cross office and donate blood? Choose to share life. Share your blood,” Villegas said in remarks posted in a Catholic church website.

Before the crucifixions, dozens of male penitents walked several kilometers through village streets, beating their bare backs with sharp bamboo sticks and pieces of wood. Some of them had their backs cut to keep them bloody.

Vietnam Stands to See Modest Wins if China, U.S. Start Trade War

A wider Sino-U.S. trade dispute would help export-reliant Vietnam compete against Chinese companies but put the country at risk of any global fallout, analysts say.

The numerous exporters in Vietnam that ship manufactured goods to the United States would save money compared with Chinese peers if not subject to American tariffs, said Dustin Daugherty, senior associate with business consultancy Dezan Shira & Associates in Ho Chi Minh City.

The U.S. government said this month it would develop a list of tariffs on up to $60 billion in Chinese imports. China has threatened to impose its own in response.

“Let’s say (the United States) went the more traditional route, tensions kept escalating and more tariffs are slapped on Chinese products,” Daugherty said. “In that case Vietnam’s export sector definitely benefits. We’re already seeing the U.S. being very warm to Vietnam and U.S. businesses keen on doing business with Vietnam.”

But Chinese firms hit by tariffs might flood Vietnam with raw materials for local manufacturing, while overall world market volatility caused by a Sino-U.S. trade dispute could hamper the country’s trade, said Carl Thayer, emeritus professor at the University of New South Wales in Australia.

​A tariff-free Vietnam scenario

Vietnamese exporters would save money compared to their Chinese peers if the U.S. government placed tariffs on Chinese firms alone without touching their cross-border supply chains, Daugherty said.

The government of U.S. President Donald Trump calls China unfair in its trade practices, the Office of the U.S. Trade Representative says on its website. China enjoys a $375 billion trade surplus with the United States.

Vietnam counts the United States as its top single-country export destination and it shipped $46.484 billion worth of goods to that market last year.

Vietnamese officials have carved out an investment environment since the 1980s that hinges on low costs for manufacturers. American-invested factories such as a Ford Motor plant and an Intel chip factory are among those active in Vietnam today.

Foreign investment contributed to exports worth $155.24 billion in 2017, financial services firm SSI Research in Hanoi says. Vietnam’s economy grew about 7 percent in the first quarter this year, it says.

Attractive investment

Vietnam would be a more attractive investment compared with China under higher U.S. tariffs, analysts say.

Some new investors might be formerly China-based firms hoping to flee the tariffs, said Song Seng Wun, an economist in the private banking unit of CIMB in Singapore.

China itself might offer Vietnam, along with other countries, preferential trade policies or infrastructure help to shore up trade ties, some believe. Stronger trade relations outside the United States would help China offset any tariff damage, Daugherty said.

This week China’s commerce minister pledged to relax trade rules affecting India.

​Specter of a broader trade war

U.S. import tariffs that hit China’s extensive cross-border supply chain would hurt Vietnam as a place that finishes Chinese goods for final export, Thayer said. It’s unclear whether Washington would tax Chinese firms alone or their wider supply networks.

Chinese firms already co-invest with Vietnamese partners, Song said, and supply chains for goods such as consumer electronics can net multiple countries, not just China.

More co-investment might follow if Vietnam can offer shelter from tariffs. But Sino-Vietnamese political tension over a maritime dispute risks giving Vietnamese firms a bad name at home if they work too extensively with Chinese partners.

“I would say there will be all kinds of repercussions and implications just because of the very integrated supply chain in the world these days,” Song said. “Take an Apple phone as an example. Parts from here and there are assembled in China.”

Steel, aluminum tariffs

U.S. steel and aluminum tariffs that took effect last week cover much of the world including China and Vietnam. Vietnam exported 380,000 tons of steel, worth $303 million, to the United States in 2017, domestic news website VnExpress International says.

Chinese firms hit by the range of tariffs being mulled now in Washington might boost sales to Vietnam, Thayer said. Chinese sellers of raw materials for Vietnamese exports could dump goods into Vietnam to keep up their own balance sheets as U.S. tariffs hurt them, he added.

Chinese sellers often have an economy of scale that lets them sell for less in Vietnam than local vendors do. Vietnam counts China as its top trading partner.

An escalation of Sino-U.S. trade tensions could also chill global markets or trade as a whole, some analysts fear. That fallout could slow global growth, he said.

“Disruption to trade shouldn’t affect Vietnam overall, but it’s the way the entire globe is reacting to this that I think could affect Vietnam,” he said. “Vietnam is overall heavily committed to global integration with a number of partners, so disruption along that way would have an effect.”

Italian Market Offers Array of Items to Help Celebrate Easter

Easter, also known as Resurrection Sunday, commemorates Jesus’ resurrection, three days after his crucifixion. It’s preceded by Lent, 40 days of fasting, prayer and repentance. While Easter is a solemn holiday for Christians, it’s also a time for families to get together around the festival holiday table, one that has been influenced by the many cultures that make up American society. VOA’s Mariama Diallo visited an Italian market owned by Suzy and Bill Menard and filed this report.

Rivers and Tides Can Provide Affordable Power

While wind turbines and solar cells generate power only when there is wind and sun, most rivers always flow and most ocean shores always experience tidal currents. At a recent energy summit organized by the U.S. Energy Department, a company from Maine displayed an innovative submersible generator that effectively harvests power from shallow rivers and tidal currents. VOA’s George Putic has more.

Despite Setbacks, Automakers Move Forward with Electric and Self-Driving Cars

A recent fatality involving one of Uber’s self-driving cars may have created uncertainty and doubt regarding the future of autonomous vehicles, but it’s not stopping automakers who say autonomous and self-driving vehicles are here to stay. At the New York International Auto Show this week, autonomous vehicles and electric cars were increasingly front and center as VOA’s Tina Trinh reports.
