Kepler Telescope Kaput After ‘Stunningly Successful’ Mission

NASA’s elite planet-hunting spacecraft has been declared dead, just a few months shy of its 10th anniversary. 

Officials announced the Kepler Space Telescope’s demise Tuesday. 

Already well past its expected lifetime, the 9½-year-old Kepler had been running low on fuel for months. Its ability to point at distant stars and identify possible alien worlds worsened dramatically at the beginning of October, but flight controllers still managed to retrieve its latest observations. The telescope has now gone silent, its fuel tank empty. 

“Kepler opened the gate for mankind’s exploration of the cosmos,” said retired NASA scientist William Borucki, who led the original Kepler science team. 

Super Earths found

Kepler discovered 2,681 planets outside our solar system and even more potential candidates. It showed us rocky worlds the size of Earth that, like Earth, might harbor life. It also unveiled incredible super Earths: planets bigger than Earth but smaller than Neptune. 

NASA astrophysics director Paul Hertz estimated that anywhere from two to a dozen of the planets discovered by Kepler are rocky and Earth-sized in the so-called Goldilocks zone — the habitable area around a star where the temperature would permit existence of liquid water. But Kepler’s overall planet census showed that 20 percent to 50 percent of the stars visible in the night sky could have planets like ours in such a habitable zone for life, he said. 

The $700 million mission even helped to uncover last year a solar system with eight planets, just like ours. 

“It has revolutionized our understanding of our place in the cosmos,” Hertz said. “Now we know because of the Kepler Space Telescope and its science mission that planets are more common than stars in our galaxy.” 

Almost lost in 2013 because of equipment failure, Kepler was salvaged by engineers and kept peering into the cosmos, thick with stars and galaxies, ever on the lookout for dips in in the brightness of stars that could indicate an orbiting planet. 

“It was like trying to detect a flea crawling across a car headlight when the car was 100 miles away,” said Borucki said. 

The resurrected mission became known as K2 and yielded 350 confirmed exoplanets, or planets orbiting other stars, on top of what the telescope had already uncovered since its March 7, 2009, launch from Cape Canaveral. 

In all, close to 4,000 exoplanets have been confirmed over the past two decades, two-thirds of them thanks to Kepler. 

Kepler focused on stars thousands of light-years away and, according to NASA, showed that statistically there’s at least one planet around every star in our Milky Way galaxy. 

Borucki, who dreamed up the mission decades ago, said one of his favorite discoveries was Kepler 22b, a water planet bigger than Earth but in an area where it is not too warm and not too cold — the type “that could lead to life.” 

Successor spacecraft

A successor to Kepler launched in April, NASA’s Tess spacecraft, has its sights on stars closer to home. It’s already identified some possible planets. 

Tess project scientist Padi Boyd called Kepler’s mission “stunningly successful.” 

Kepler showed us that “we live in a galaxy that’s teeming with planets, and we’re ready to take the next step to explore those planets,” she said. 

Another longtime spacecraft chasing strange worlds in our own solar system, meanwhile, is also close to death. 

NASA’s 11-year-old Dawn spacecraft is pretty much out of fuel after orbiting the asteroid Vesta as well as the dwarf planet Ceres. It remains in orbit around Ceres, which, like Vesta, is in the asteroid belt between Mars and Jupiter. 

Two of NASA’s older telescopes have been hit with equipment trouble recently, but have recovered. The 28-year-old Hubble Space Telescope resumed science observations last weekend, following a three-week shutdown. The 19-year-old Chandra X-ray Telescope’s pointing system also ran into trouble briefly in October. Both cases involved critical gyroscopes, needed to point the telescopes. 

Hertz said all the spacecraft problems were “completely independent” and coincidental in timing. 

Now 94 million miles from Earth, Kepler should remain in a safe, stable orbit around the sun. Flight controllers will disable the spacecraft’s transmitters, before bidding it a final “goodnight.” 

UN Sets Out Massive Benefits from Air Pollution Action in Asia

Asia could reap massive benefits in health, environment, agriculture and economic growth if governments implement 25 policies such as banning the burning of household waste and cutting industrial emissions, according to a U.N. report.

Air pollution is a health risk for 4 billion people in Asia, killing about 4 million of them annually, and efforts to tackle the problem are already on track to ensure air pollution is no worse in 2030, but huge advances could be made, the report said.

The report’s 25 recommendations would cost an estimated $300 billion to $600 billion annually, a big investment but loose change compared with a projected $12 trillion economic growth increase.

The publication of the report, “Air Pollution in Asia and the Pacific: Science based solutions,” on Tuesday coincides with the World Health Organization holding its first global air pollution conference in Geneva this week

The recommendations also included post-combustion controls to cut emissions from power stations, higher standards for shipping fuels, ending routine flaring of gas from oil wells, and energy efficiency standards for industry and households.

The biggest gains would come from clean cooking, reducing emissions from industry, using renewable fuels for power generation and more efficient use of fertilizers.

Huge improvements in post-combustion controls and emission standards for road vehicles were already anticipated because of recent legislation, although both could be improved further.

Indeed, India may halt the use of private vehicles in the capital New Delhi if air pollution, which has reached severe levels in recent days, gets worse, a senior environmental official said Tuesday.

Authorities in the capital have already advised residents to keep outdoor activity to a minimum from the beginning of next month until at least the end of the Hindu festival of Diwali on Nov. 7, when firecrackers typically further taint air choked by the burning of crop stubble in neighboring states.

Helena Molin Valdes, head of Climate and Clean Air Coalition Secretariat at U.N. Environment, said there was increasing political openness to taking action on air pollution and the report reflected three years of discussions with governments.

“What the governments were saying in the region was: ‘Don’t tell us we have a problem, we know there is a problem, how can we deal with it and what will it take to do it?'” she said.

The report estimates its recommendations would cut carbon dioxide emissions by 20 percent compared to a baseline scenario, potentially decreasing global warming by one-third of a degree Celsius by 2050, which would also be a contribution in the fight against climate change.

One billion people would enjoy high air quality, while the number exposed to the worst pollution would be cut by 80 percent to 430 million. Premature deaths would fall by a third.

Crop yields would benefit because of a reduction in ozone, which is estimated to have cut 2015 harvests by 10 percent for maize, 4 percent for rice, 22 percent for soy and 9 percent across Asia, a total of 51 million tons.

Soviet-Era Moon Fragments Could Reach $1 Million at NY Auction

Wealthy space buffs will have the chance to own three small particles of lunar matter when what Sotheby’s describes as the only known documented “moon rocks” to be legally available for private ownership hit the auction block in November.

Sotheby’s said on Tuesday it expects the fragments, retrieved from the moon by a Soviet space mission in 1970, could fetch between $700,000 to $1 million at the Nov. 29 auction in New York.

The pieces — a basalt fragment, similar to most of the Earth’s volcanic rock, and bits of surface debris known as regolith — are being sold by an unidentified private American collector who purchased them in 1993.

Sotheby’s said in a statement they were first sold in 1993 by Nina Ivanovna Koroleva, the widow of former Soviet space program director Sergei Pavlovich Korolev.

The fragments, ranging in size from about .079 inch x .079 inch (2 x 2mm) to .039 inch x .039 inch (1 x 1mm), were presented to her as a gift on behalf of the Soviet Union in recognition of her late husband’s contributions to the program.

Sotheby’s said that the particles, encased under glass with a Russian plaque, are both the only known lunar sample to have ever been officially gifted to a private party, and with documented provenance to be available for private ownership.

Collectors pay huge sums for space exploration artifacts.

Last year, Sotheby’s sold a zippered bag stamped with the words “Lunar Sample Return” laced with moon dust which was used by Neil Armstrong for the first manned mission to the moon in 1969, for $1.8 million.

That sale took place after NASA lost a court battle to retrieve the artifact from a private collection.

Most other known samples taken from the moon remain with the two entities that collected them: the United States during the Apollo 11-17 missions and the Soviet Union via the unmanned Luna-16, Luna-20, and Luna-24 missions.

A number of other countries were gifted with Apollo 11 samples and Apollo 17 goodwill moon rocks on behalf on the Nixon administration, and in most places the law bars transferring such gifts to individuals.

The particles being sold in November were retrieved in September 1970 by Luna-16 which drilled a hole in the surface to a depth of 13.8 inches (35 cm) and extracted a core sample.

They are encased under glass below an adjustable lens and labeled “ЧАСТИЦЫ ГРУНТА ЛУНЫ-16″ [SOIL PARTICLES FROM LUNA-16].”

Tests on similar samples have dated the bits as being as much as 3.4 billion years old.

NFL to Schedule 4 London Games in 2019

London will play host to four NFL games in the 2019 season, the league’s United Kingdom office announced Tuesday.

The league did not say which teams would play and did not disclose the game dates.

Two of the games will be played at Wembley Stadium, with the others at the stadium being built for Premier League team Tottenham.

Three NFL games were played in London this year. 

There have been 24 regular-season games played in London since the league began scheduling games there in 2007. All but three of the NFL’s 32 teams have made at least one London trip.

Zimbabwe’s President Assures Nation Economy Will Recover

Zimbabwe’s President Emmerson Mnangagwa met with business leaders Monday to discuss ways of boosting the country’s troubled economy. He suggested companies are contributing to shortages by holding back essential goods, but one of the businessman said the accusation is not true. Columbus Mavhunga reports for VOA News from Harare.

Apple’s New iPads Embrace Facial Recognition

Apple’s new iPads will resemble its latest iPhones as the company ditches a home button and fingerprint sensor to make room for the screen.

 

As with the iPhone XR and XS models, the new iPad Pro will use facial-recognition technology to unlock the device and authorize app and Apple Pay purchases.

 

Apple also unveiled new Mac models at an opera house in New York, where the company emphasized artistic uses for its products such as creating music, video and sketches. New Macs include a MacBook Air laptop with a better screen.

 

Research firm IDC says tablet sales have been declining overall, though Apple saw a 3 percent increase in iPad sales last year to nearly 44 million, commanding a 27 percent market share.

 

African Filmmaker Tells Tales of South African Migrants

In his latest film “Vaya,” Nigerian-born director Akin Omotoso explores the themes of migration and coming of age. 

“Vaya” tells the story of three strangers who get on a train, each of them with a mission to fulfill in Johannesburg. They’re coming from Durban to Johannesburg. They never meet, but their stories are intertwined,” Omotoso explained.

Each traveler has a mission. A young man is promised a job that is not what he expected. Another is sent to reclaim his father’s body — a task that is surprisingly difficult. A young woman escorts a young girl to her family in the city. Each faces rejection, abuse or violence.

The film came from the real-life stories of South Africans in the Homeless Writers Project, a workshop for people living on the streets of Johannesburg.

Vaya means “to go” in the Tsotsitaal dialect used in South African townships.

“It takes on several meanings. So, ‘to go’ — they’re leaving Durban to go to Johannesburg. But when they get there, maybe people don’t want you. They want you to go,” Omotoso said. 

The director is a migrant himself. He was born in Nigeria, but his family moved to South Africa, where his father, the writer Kole Omotoso, was a professor at the University of the Western Cape. Akin studied drama at the university, and then worked as an actor and director.

“Vaya” is one of 20 movies by filmmakers of color or female directors distributed by Array, a Los Angeles-based collective and distribution company founded by director Ava DuVernay.

“Our purpose is to make sure that audiences have access to films they otherwise would not see, those independent voices that deserve a platform for stories to be told,” said Mercedes Cooper, Array’s director of marketing.

“Vaya” was released in 2016 and has played at international festivals. It opened in U.S. theaters in late October and will stream on Netflix starting Nov. 1. Omotoso said many can relate to this story.

“I always say everyone has a cousin who’s arriving, or a brother who’s leaving, or somebody who’s coming,” he said. “So, “Vaya” is able to tap into something that doesn’t just happen in Johannesburg.”

The film taps into universal themes, notes Omotoso, such as the search for a better life and the struggle for survival. 

“It’s a thrilling ride when you start to put together the mystery of what’s going on.”

Women Make their Mark at Comicon

Each October, fans of comics, anime, graphic novels and manga…Japanese comics…descend on New York for Comic Con. A highlight of the international pop culture festival is cosplay. Cosplayers dress as characters from their favorite comics, and this year, as reporter Asli Pelit discovered, there were more women in costume. Faith Lapidus narrates.

How Old is Cacao? New Research Pushes Back Date

New research strengthens the case that people used the chocolate ingredient cacao in South America 5,400 years ago, underscoring the seed’s radical transformation into today’s Twix bars and M&M candies.

 

Tests indicate traces of cacao on artifacts from an archaeological site in Ecuador, according to a study published Monday. That’s about 1,500 years older than cacao’s known domestication in Central America.

 

“It’s the earliest site now with domesticated cacao,” said Cameron McNeil of Lehman College in New York, who was not involved in the research.

 

The ancient South American civilization likely didn’t use cacao to make chocolate since there’s no established history of indigenous populations in the region using it that way, researchers led by the University of British Columbia in Canada said.

 

But the tests indicate the civilization used the cacao seed, not just the fruity pulp. The seeds are the part of the cacao pod used to make chocolate.

 

Indigenous populations in the upper Amazon region today use cacao for fermented drinks and juices, and it’s probably how it was used thousands of years ago as well, researchers said.

Scientists mostly agree that cacao was first domesticated in South America instead of Central America as previously believed. The study in Nature Ecology & Evolution provides fresh evidence.

 

Three types of tests were conducted using artifacts from the Santa Ana-La Florida site in Ecuador. One tested for the presence of theobromine, a key compound in cacao; another tested for preserved particles that help archeologists identify ancient plant use; a third used DNA testing to identify cacao.

 

Residue from one ceramic artifact estimated to be 5,310 to 5,440 years old tested positive for cacao by all three methods. Others tested positive for cacao traces as well, but were not as old.

 

How cacao’s use spread between South America and Central America is not clear. But by the time Spanish explorers arrived in Central America in the late 1400s, they found people were using it to make hot and cold chocolate drinks with spices, often with a foamy top.

 

“For most of the modern period, it was a beverage,” said Marcy Norton, a historian at the University of Pennsylvania and author of “Sacred Gifts, Profane Pleasures: A History of Tobacco and Chocolate in the Atlantic World.”

 

The chocolate drinks in Central America often contained maize and differ from the hot chocolate sold in the U.S. They did not contain milk, Norton said, and when they were sweetened, it was with honey.

 

By the 1580s, cacao was being regularly imported into Spain and spread to other European countries with milk being added along the way. It wasn’t until the 1800s that manufacturing advances in the Netherlands transformed chocolate into a solid product, Norton said.

Michael Laiskonis, who teaches chocolate classes the Institute of Culinary Education, said he’s seeing a growing interest in cacao flavors, indicating a return to a time when chocolate wasn’t just an ingredient buried in a candy bar.

He said he tries to incorporate chocolate’s past into his classes, including a 1644 recipe that combines Mayan and Aztec versions of drinks with European influences.

 

“It’s something that’s always been transforming,” he said.

Zimbabwean Widows Punished by Tribal Courts for Selling Gold-rich Land

When massive gold deposits were discovered about a decade ago in Chimanimani, eastern Zimbabwe, the rural district became famous for attracting hundreds of artisanal miners from across the country every year.

Wealthy small-scale prospectors regularly offer residents generous deals for their land, locals say. To many widows selling their unused land, that kind of money can be life-changing and a source of greater autonomy.

But in recent years, widows in Chimanimani have found that taking a deal can have consequences. Many say they have been taken to tribal courts by their husbands’ families for selling portions of their land.

“I feel bruised,” said Mavis, a 63-year-old widow from Haroni village who did not want to disclose her surname.

“I lived in peace as a widow in my home until last year, when I sold an unwanted acre of my late husband’s land to korokoza,” she said, using a colloquial term for an artisanal gold miner.

He paid her $2,000 in cash. “All hell broke loose,” Mavis explained.

When her male relatives found out about the sale, they reported her to the tribal court.

“The accusations were insane. They said I bewitched my husband, even though he died way back in 1979, in the colonial war,” she told the Thomson Reuters Foundation.

The cultural norms of the Ndau people, who make up the majority of the population in Chimanimani, forbid widows from owning land their husbands leave behind or selling that land unless a male family member controls the transaction.

As her uncles laid claim to her late husband’s property, Mavis joined a growing number of widows whose male family members have denied them the right to sell land they are supposed to legally inherit.

“In our village, I am the fourth widow since 2017 to be brought to (tribal court) for selling land without male approval,” she said.

Her case is still ongoing.

Tribal Justice

According to Zimbabwe’s latest census, which was conducted in 2012, there are more than half a million widows in the country.

Throughout rural areas, widows routinely find themselves harassed and exploited by in-laws claiming the property their husbands left behind, rights activists say.

O’bren Nhachi, an activist and researcher focusing on natural resources and governance, said the problem has gotten worse in Chimanimani over the past few years, as the gold rush has pushed up the value of land.

“Chimanimani was a poor backwater district until gold was discovered. Suddenly, local land prices shot up because artisanal gold diggers are paying huge sums to snap up plots,” he said. “This has brought conflict, with male family members using patriarchy as a tool to dispossess widows of potential land sales income.”

Although Zimbabwe’s constitution gives women and men equal rights to property and land, in many rural communities tradition overrides national legislation, experts say.

Tribal custom dictates that chiefs are the custodians of communal land, and responsible for allocating land to villagers.

“A woman cannot sell land unless she has obtained permission from my Committee of Seven,” said Mutape Moyo, a tribal headman in Chimanimani, referring to the group of elders — all men — who hear cases in the local customary court.

But this makes it unclear who has legal ownership of land, Nhachi said.

“The laws of the country say the state is the owner of all land. Tribal chiefs are merely ‘custodians’. Does custodian mean they are owners?”

In a country where women carry out 70 percent of the agricultural work – according to the U.N. Food and Agriculture Organization – Nhachi said more women need to be made aware of how to legally hold onto their land if their husbands die.

He said he would like to see the government implement legal awareness programs and properly define who owns and distributes land in rural Zimbabwe.

No Recourse

Provincial administrator Edward Seenza, the head civil servant of Manicaland province, where Chimanimani is located, said that if widows lose their land in tribal courts, there are ways for them to appeal and reverse the ruling.

“If anyone is unhappy with a village head’s decision, they can speak to a chief,’ he said. “Where this does not produce the desired result, they can take their complaint to the district administrator and further up to my office.”

But activists say few rural women know they have that option. And those who do are often too poor or too scared to travel to a government office.

Seenza said that so far, not one woman has come to him to appeal a tribal court ruling.

And without legal help, widows denied the right to sell their land can be left devastated.

Rejoice, a 38-year-old widow from Chipinge district, sold her late husband’s mango orchard two years ago to a wealthy gold digger for $4,000. She needed the money to pay for medication to treat a kidney tumor.

Her father-in-law took her to tribal court.

“I was ordered to refund the buyer, in cash, with punitive interest; pay court fines for ‘disrespect’; and surrender the rest of the land to male family custodians,” said Rejoice, whose name has been changed to protect her identity.

She paid back the buyer as much as she could, but still owes him some money. And her husband’s family is still fighting for ownership of the land, she added.

The court told her that if she does not honor the ruling, she could be thrown out of her home.

“I will end up a destitute, living on the roadside,” she said. “The thought of this gives me sleepless nights.”

Mountain Birds on ‘Escalator to Extinction’ as Planet Warms

A meticulous re-creation of a three-decade-old study of birds on a mountainside in Peru has given scientists a rare chance to prove how the changing climate is pushing species out of the places they are best adapted to. 

Surveys of more than 400 species of birds in 1985 and then in 2017 have found that populations of almost all had declined, as many as eight had disappeared completely, and nearly all had moved to higher elevations in what scientists call “an escalator to extinction.” 

“Once you move up as far as you can go, there’s nowhere else left,” said John W. Fitzpatrick, a study author and director of the Cornell Laboratory of Ornithology. “On this particular mountain, some ridgetop bird populations were literally wiped out.”

It’s not certain whether the birds shifted ranges because of temperature changes, or indirect impacts, such as shifts in the ranges of insects or seeds that they feed on. 

These findings, published Monday in the Proceedings of the National Academy of Sciences, confirm what biologists had long suspected, but had few opportunities to confirm. The existence of a 1985 survey of birds on the same mountain gave scientists a rare and useful baseline. 

Past research has documented habitats of birds and other species moving up in elevation or latitude in response to warming temperatures. But Mark Urban, director of the Center of Biological Risk at the University of Connecticut, who was not involved in the study said it was the first to prove what climate change models predicted: that rising temperatures will lead to local extinctions.

“A study like this where you have historical data you can go back to and compare is very rare,” said Urban. “As long as the species can disperse, you will see species marching up the mountain, until that escalator becomes a stairway to heaven.”

In 1985, Fitzpatrick established a basecamp alongside a river running down a mountain slope in southeastern Peru, aiming to catalog the habitat ranges of tropical bird species that lived there. His team spent several weeks trekking up and down the Cerro de Pantiacolla, using fine nets called mist nets to catch and release birds, and keeping detailed journals of birds they caught, spotted or heard chirping in the forests.

Two years ago, Fitzpatrick passed his journals, photos and other records to Benjamin Freeman, a postdoctoral fellow at the Biodiversity Research Centre at the University of British Columbia. Freeman, who has been researching tropical birds for more than a decade, set out to recreate the journey in August and September of 2017. Using old photos of mountain views, his team located the same basecamp. 

Freeman largely recreated Fitzpatrick’s path and methodology to see what had happened in the intervening years, a period when average mean temperatures on the mountain rose 0.76 degrees Fahrenheit (0.42 degrees Celsius). Because the mountain lies at the edge of a national park, the area hadn’t been disturbed. 

In addition to unfurling 40-foot (12-meter) mist nets on the slopes, Freeman’s team placed 20 microphone boxes on the mountain to record the chirps of birds that might not easily be seen.

“We found that the bird communities were moving up the slope to reach the climate conditions to which they were originally adapted,” said Freeman, the lead author of the study. Near the top of the mountain the bird species moved higher by 321 feet (98 meters), on average.

“We think temperature is the master-switch in explaining why species live where they do on mountain slopes,” said Freeman. “A huge majority of species in our study were doing the same thing.”

Birds adapted to live within narrow temperature bands — in regions without wide seasonal variations — may be particularly vulnerable to climate change, Fitzpatrick said.

“We should expect that what’s happening on this mountaintop is happening more generally in the Andes, and other tropical mountain ranges,” he said. 

 

 

US Survey: What Pay Gap? Men Less Aware of Women’s Workplace Struggles

Far more men than women think their companies offer equal pay and promote the sexes equally, yet younger generations are wising up, a U.S. entertainment industry survey found on Monday.

Only a quarter of women think their employers pay them the same as men, while twice as many men believe their company has no gender pay gap, according to the survey by CNBC, a business news channel, and job-oriented social networking site LinkedIn.

About one third of women said both sexes rise up the ranks at the same rate in their workplaces, while more than half of men think the promotion rates are equal, according to responses from at least 1,000 LinkedIn members who work in entertainment.

“Men, typically we found across industries … they’re not as cognizant as their female counterparts to these issues,” said Caroline Fairchild, managing editor at LinkedIn.

Other surveys in finance and technology have revealed similar findings, she told the Thomson Reuters Foundation.

Congress outlawed pay discrimination based on gender in the federal Equal Pay Act in 1963, yet public debate over why wages still lag drastically for women has snowballed in recent years.

Last year in the United States, working women earned 82 percent of what men were paid, the Pew Research Center found.

According to the CNBC-LinkedIn survey, four in five women said the workplace holds more obstacles to advancement for women than for men, but only about half of men held the same opinion.

However the survey found that younger men were more likely than their older peers to say they were aware of the obstacles that stop women from succeeding at work, according to Fairchild.

“Perhaps the old guard of the industry is thinking a certain way, but we are seeing a perception change in what perhaps younger people in the industry are thinking,” she added.

A U.S. appeals court in San Francisco ruled in April that employers cannot use workers’ salary histories to justify gender-based pay disparities, saying that would perpetuate a wage gap that is “an embarrassing reality of our economy.”

A handful of U.S. cities and states ban employers from asking potential hires about their salary histories.

The World Economic Forum reported a global economic gap of 58 percent between the sexes for 2016 and forecast women would have to wait 217 years before they are treated equally at work.

Gender inequality in the workplace could cost the world more than $160.2 trillion in lost earnings, according to the World Bank. The figure compares the difference in lifetime income of everyone of working age and if women earned as much as men.

Scientists: Producing Bitcoin Currency Could Void Climate Change Efforts

Demand for bitcoin could single-handedly derail efforts to limit global warming because the increasingly popular digital currency takes huge amounts of energy to produce, scientists said on Monday.

Producing bitcoin at a pace with growing demand could by 2033 defeat the aim of limiting global warming to 2 degrees Celsius, according to U.S. research published in the journal Nature Climate Change.

Almost 200 nations agreed in Paris in 2015 on the goal to keep warming to “well below” a rise of 2°C above pre-industrial times.

But mining, the process of producing bitcoins by solving mathematical equations, uses high-powered computers and alto of electricity, the researchers said.

“Currently, the emissions from transportation, housing and food are considered the main contributors to ongoing climate change,” said study co-author Katie Taladay in a statement. “This research illustrates that bitcoin should be added to this list.”

Mining is a lucrative business, with one bitcoin currently selling for about $6,300 (4,900 British pounds).

In 2017, bitcoin production and usage emitted an estimated 69 million metric tons of carbon dioxide equivalent, the researchers said.

That year, bitcoin was involved in less than half of 1 percent of the world’s cashless transactions, they said.

As the currency becomes more common, researchers said it could use enough electricity to emit about 230 gigatons of carbon within a decade and a half. One gigaton is equal to one billion metric tons of carbon.

“No matter how you slice it, that thing is using a lot of electricity. That means bad business for the environment,” Camilo Mora, another co-author, told the Thomson Reuters Foundation.

Bitcoin mining, however, is becoming more energy efficient, said Katrina Kelly-Pitou, research associate at the University of Pittsburgh.

She said bitcoin miners are moving away from sites such as China, with coal-generated electricity, to more environmentally friendly utilities in Iceland and the United States.

Iran Silent on S. Korea’s Hyundai Quitting Major Construction Project 

South Korean conglomerate Hyundai’s cancellation of a major Iran construction project due to problems related to U.S. economic sanctions has been met with silence in Iranian media.

In a brief regulatory filing published Monday, Hyundai Engineering & Construction said it canceled a $521 million contract a day earlier for building a petrochemicals complex in Iran.

“The contract was canceled because financing is not complete, which was a prerequisite for the validity of the contract, as external factors worsened, such as economic sanctions against Iran,” Hyundai said.

Twelve hours after Hyundai made the announcement, there were no mentions of it in Iranian state-controlled media. There also was little Farsi-language discussion of the move on Twitter.

The United States is set to reimpose sanctions on Iran’s key energy exports on Nov. 4 to try to pressure Tehran into agreeing to a new deal to curb its nuclear and other perceived malign activities. Energy exports are the main sources of revenue for the Iranian government. 

For months, international companies in sectors such as energy, aviation, autos and shipping have been withdrawing from or scaling back business with Iran to avoid being hit by secondary U.S. sanctions for continuing such business as the primary U.S. sanctions take effect. 

Speaking to the Monday edition of VOA Persian’s News at Nine program, Johns Hopkins University applied economics professor Steve Hanke said cancellations of Iranian construction contracts by Hyundai and other foreign companies cause significant delays in the construction process.

“Now, the Iranians have to more or less start over and find somebody new. All of this takes time. As it takes time, the Iranian economy sinks,” Hanke said. 

Facing growing domestic discontent with Iran’s faltering economy, President Hassan Rouhani won parliamentary approval Saturday for a reshuffle of economic posts in his cabinet. He also said Iran can withstand U.S. sanctions by turning to other nations for business.

“Russia, China, India, the European Union and some African and Latin American countries are our friends,” he told parliament. “We have to work with them and attract investments.”

Hanke said it is more likely that Iran will finance the petrochemical project abandoned by Hyundai with Chinese and Russian partners than with the EU. Washington has put particular pressure on its European allies in recent months not to undermine U.S. sanctions against Iran. 

The EU has said it will try to circumvent U.S. sanctions by setting up a “special purpose vehicle” to facilitate transactions between European businesses and Iran. The 28-nation bloc has said it will abide by a 2015 deal between Iran and world powers, curbing Iranian nuclear activities in return for relief from international sanctions. U.S. President Donald Trump withdrew from that deal in May, saying it was not tough enough on Iran. Tehran denies seeking nuclear weapons. 

South Korea, a key U.S. ally in East Asia, has not vowed to defy U.S. sanctions, but it does appear to want to salvage its remaining commercial contracts with Iran. South Korean media said Foreign Minister Kang Kyung-wha spoke by phone with U.S. Secretary of State Mike Pompeo on Monday and asked Washington to be flexible in exempting South Korean companies from U.S. penalties for Iran-related business. There was no immediate readout of the phone call from the U.S. State Department. 

Hyundai had signed a contract to build a petrochemical complex on Iran’s Persian Gulf coast near the southern town of Tonbak in March 2017. South Korean and Iranian media said the contract was for the construction of the second phase of the Kangan Petro Refining Complex in the South Pars Gas Field. The reports valued Hyundai’s contract with Iran’s Ahdaf Investment Company, an affiliate of a state-run oil firm, at $3 billion. 

Hyundai, in its Monday statement, did not explain the discrepancy between the initially reported $3 billion valuation of the contract and its latest $512 million valuation.

Rock Band Kiss Promises ‘Unapologetic’ Final Tour

Members of the rock band Kiss said they are kicking off a farewell concert tour in January because they wanted to say goodbye while they could still deliver the over-the-top performances that have thrilled audiences over a 45-year career.

Known for their makeup, big hair and outrageous costumes, Kiss was among the biggest acts of the 1970s, coming out of the glam rock era with hits including “Rock and Roll All Nite.”

“How pathetic and sad would it be to see the band, and you’ve seen lots of them, (where) you remember their glory days and they’re out there a little bit too long,” said 69-year-old bassist and singer Gene Simmons.

“We have too much pride and self-respect in us, and too much love for our fans, to not live up to our self-imposed mandate,” he added. “You wanted the best, you got the best, the hottest band in the world.”

The “End of the Road” tour will start Jan. 31 in Vancouver.

It is expected to last two to three years and extend around the world, Simmons said.

“Earth is a big place and we’re going to go to every corner,” he said.

Kiss has sold more than 100 million albums over its career.

It served as a predecessor to 1980s heavy metal acts such as Motley Crue. Kiss currently includes two original members – Simmons along with singer and guitarist Paul Stanley – plus guitarist Tommy Thayer and drummer Eric Singer.

“I guarantee that the people who come that have never seen us before are going to say ‘Why did we wait so long?,'” 66-year-old Stanley said, “because this is going to be bombastic, explosive, unapologetic and a celebration of everything we’ve done.”

“The word ‘bittersweet’ doesn’t really enter into it,” he added. “For us, it’s a celebration. We want to go out on top while we can still do what we do.”

Frank Underwood is Dead but Looms Large in Final ‘House of Cards’ Season

In the final season of Netflix’s “House of Cards,” Frank Underwood is physically gone, having died unexpectedly in his sleep. But the ghost of the win-at-all-costs politician played by Kevin Spacey haunts his wife and her young presidency.

Writers of the acclaimed drama had to rework the story after Spacey was accused of sexual misconduct a year ago and dropped from the show that made Netflix a player in premium television.

The ending of the Underwoods’ story, which the producers called a “season of reckoning,” will be available on Netflix on Nov. 2.

At last season’s conclusion, Frank’s statuesque wife Claire, played by Robin Wright, looked into the camera and declared “my turn” as the power shifted and she became the first female U.S. president.

After Spacey’s departure, executive producers and writers Frank Pugliese and Melissa James Gibson said everyone involved in the show felt they wanted to go ahead with a sixth and final season.

“What would it been like to actually rob her turn?” Pugliese said in an interview. “It seemed like an impossible, unacceptable way to end it that way.”

The eight new episodes do not dance around Frank’s absence.

The first episode reveals early on that he died in bed but makes the cause of his death the subject of an ongoing mystery.

“It would have felt really dishonest to try and erase him essentially as a character,” Gibson said. “I think that wouldn’t have honored the seeds of the show.”

Spacey was nominated for five Emmys for his “House of Cards” role. But last November, Netflix quickly cut ties with the actor after allegations of sexual misconduct surfaced. He has been accused by more than 20 men and has said nothing publicly about the allegations since an apology to the first accuser in October 2017.

Throughout the final “House of Cards” season, Claire is forced to constantly grapple with her late husband’s deals and the compromises she made with him.

“She is trying to carve out her own path and in doing so she has the opportunity and obligation to really face herself in a profound way,” Gibson said.

Claire also has to figure out who she can trust as the White House is destabilized with Frank out of picture, a scenario that provided the writers with rich story lines, they said.

“The circumstances became opportunities that I hope this season fulfills,” Pugliese said.

UN Human Rights Expert Urges States to Curb Intolerance Online

Following the shooting deaths of 11 worshippers at a synagogue in the eastern United States, a U.N. human rights expert urged governments on Monday to do more to curb racist and anti-Semitic intolerance, especially online.

“That event should be a catalyst for urgent action against hate crimes, but also a reminder to fight harder against the current climate of intolerance that has made racist, xenophobic and anti-Semitic attitudes and beliefs more acceptable,” U.N. Special Rapporteur Tendayi Achiume said of Saturday’s attack on a synagogue in Pittsburgh, Pennsylvania.

Achiume, whose mandate is the elimination of racism, racial discrimination, xenophobia and related intolerance, noted in her annual report that “Jews remain especially vulnerable to anti-Semitic attacks online.”

She said that Nazi and neo-Nazi groups exploit the internet to spread and incite hate because it is “largely unregulated, decentralized, cheap” and anonymous.

Achiume, a law professor at the University of California, Los Angeles (UCLA) School of Law, said neo-Nazi groups are increasingly relying on the internet and social media platforms to recruit new members.

Facebook, Twitter and YouTube are among their favorites.

On Facebook, for example, hate groups connect with sympathetic supporters and use the platform to recruit new members, organize events and raise money for their activities. YouTube, which has over 1.5 billion viewers each month, is another critical communications tool for propaganda videos and even neo-Nazi music videos. On Twitter, according to one 2012 study cited in the special rapporteur’s report, the presence of white nationalist movements on that platform has increased by more than 600 percent.

The special rapporteur noted that while digital technology has become an integral and positive part of most people’s lives, “these developments have also aided the spread of hateful movements.”

She said in the past year, platforms including Facebook, Twitter and YouTube have banned individual users who have contributed to hate movements or threatened violence, but ensuring the removal of racist content online remains difficult.

Some hate groups try to get around raising red flags by using racially coded messaging, which makes it harder for social media platforms to recognize their hate speech and shut down their presence.

Achiume cited as an example the use of a cartoon character “Pepe the Frog,” which was appropriated by members of neo-Nazi and white supremacist groups and was widely displayed during a white supremacist rally in the southern U.S. city of Charlottesville, Virginia, in 2017.

The special rapporteur welcomed actions in several states to counter intolerance online, but cautioned it must not be used as a pretext for censorship and other abuses. She also urged governments to work with the private sector — specifically technology companies — to fight such prejudices in the digital space.

US Steel Tariff Fight Stirs Up Swarm of WTO Litigation

The United States urged European Union governments on Monday to reflect on whether it was really in their interest to go ahead with a trade dispute over U.S. metals tariffs, and said it was hopeful of settling the issue with Mexico and Canada.

The U.S. tariffs attracted an unprecedented seven requests for WTO adjudication, as well as a slew of criticism, at a fractious WTO dispute settlement meeting, while the United States hit back with legal actions against its critics.

Shea not surprised

U.S. Ambassador Dennis Shea said he was not surprised by China’s opposition, since it had massive overcapacity in metals production and was a non-market economy, but that Washington was “deeply disappointed” with the EU’s stance.

“We would encourage the European countries to consider carefully their broader economic, political, and security interests,” Shea told the meeting.

“We will not allow China’s party-state to fatally undermine the U.S. steel and aluminum industries, on which the U.S. military, and by extension global security, rely.”

China’s representative responded by saying the United States was shifting its arguments to disguise its protectionism.

Canada and Mexico have also challenged the tariffs — 25 percent on steel and 10 percent on aluminium — but a U.S. trade official told the meeting that, after constructive discussions, Washington was hopeful of reaching an agreement with both.

Adam Austen, a spokesman for Canadian foreign minister Chrystia Freeland, told Reuters the best outcome would be for Washington to rescind the tariffs.

Taboo no longer

Norway, Russia and Turkey also asked the WTO to judge the legality of the U.S. tariffs, despite Washington’s assertion that they are based on national security and therefore outside WTO jurisdiction.

National security claims were taboo for most of the WTO’s 23-year history, because trade diplomats feared a domino effect as countries cited national security to get out of a wide range of obligations. But Shea suggested it would be even worse to try to challenge the U.S. national security claim.

“The United States wishes to be clear: if the WTO were to undertake to review an invocation of (the national security exemption), this would undermine the legitimacy of the WTO’s dispute settlement system and even the viability of the WTO as a whole,” he said.

Trachtman turns to Twitter

On Twitter, Joel Trachtman, professor of International Law at Fletcher School of Law and Diplomacy, and Jennifer Hillman, an American former WTO judge, said Shea’s position was not supported by WTO law.

Canada’s representative at the WTO meeting said fear of a national security threat was “inconceivable”, while Norway said it was “evidently divorced from real-world security concerns.”

Canada, China, the EU, Mexico and Japan argued that the U.S. tariffs were “safeguard” measures that could be addressed with sanctions under WTO rules. Washington for its part requested WTO adjudication of their retaliatory measures taken by Canada, China, the EU and Mexico.

All the requests for WTO adjudication will need to be confirmed at another meeting next month before going ahead.

Wall Street Drops on Trade Worries, S&P Nears Correction

U.S. stocks fell on Monday in a volatile session, with the S&P 500 ending just shy of confirming its second correction of 2018, hurt by fresh worries of an escalation of U.S.-China trade tensions and a sharp drop in big tech and Internet names.

Following a morning rally, major U.S. indexes pulled back steeply after a Bloomberg report that the United States is preparing to announce tariffs on all remaining Chinese imports by early December if talks next month between presidents Donald Trump and Xi Jinping falter.

“Obviously this trade skirmish is metastasizing potentially into something worse than it already is,” said Mark Luschini, chief investment strategist at Janney Montgomery Scott in Philadelphia.

After the S&P 500 dropped more than 10 percent from its Sept. 20 record closing high during the session, the benchmark index pared its losses late to close down 9.9 percent from its peak. The Dow industrials also fell more than 10 percent from its Oct. 3 record close during the session, before ending down 8.9 percent from the mark.

On Monday, the Dow Jones Industrial Average fell 245.39 points, or 0.99 percent, to 24,442.92, the S&P 500 lost 17.44 points, or 0.66 percent, to 2,641.25 and the Nasdaq Composite dropped 116.92 points, or 1.63 percent, to 7,050.29.

Major tech and growth stocks, such as Amazon.com, Google parent Alphabet and Netflix, posted sharp declines. The S&P 500 technology sector fell 1.8 percent.

The so-called FANG growth stocks – Facebook, Amazon, Netflix and Alphabet – have lost more than $200 billion in market value in the past two sessions.

The industrials sector, which is seen as sensitive to trade issues, dropped 1.7 percent, with Boeing tumbling 6.6 percent.

“The concern about global growth and global trade … continues to create an overhang for U.S. corporations and global equities,” said Chad Morganlander, senior portfolio manager at Washington Crossing Advisors in Florham Park, New Jersey.

“Growth stocks typically do poorly in situations of global growth decelerating,” he said. “You set yourself up for a more defensive market until there’s a clear sign that investors can grab hold of.”

Market volatility has spiked in recent weeks, stemming from higher interest rates and worries about the economy and trade tensions. Investors also may be increasingly nervous about uncertainty surrounding U.S. congressional elections, now just a week away.

“Probably the most pervasive headwind is concern about midterm elections,” said Kristina Hooper, chief global market strategist at Invesco. “That is weighing down stocks, particularly technology as there is greater concern about regulation.”

Internet stocks also may have been wounded by Britain’s plan to tax the revenue from online platforms.

In corporate news, shares of software maker Red Hat surged 45.4 percent after the company agreed to be bought by IBM Corp for $34 billion. But IBM shares fell 4.1 percent, weighing on the Dow and S&P.

Investors who are bullish about stocks point to strong corporate profits this year and economic strength. But there are also concerns about the extent of a slowdown in earnings growth next year, while weak housing data has raised some worries about the economy.

Data on Monday showed U.S. consumer spending rose for a seventh consecutive month in September. But income recorded its smallest gain in more than a year amid moderate wage growth, suggesting the current pace of spending was unlikely to be sustained.

Declining issues outnumbered advancing ones on the NYSE by a 1.45-to-1 ratio; on Nasdaq, a 1.45-to-1 ratio favored decliners.

The S&P 500 posted three new 52-week highs and 65 new lows; the Nasdaq Composite recorded 23 new highs and 260 new lows.

About 9.3 billion shares changed hands in U.S. exchanges, above the 8.5 billion daily average over the last 20 sessions.

How Green Is My Forest? There’s an App to Tell You

A web-based application that monitors the impact of successful forest-rights claims can help rural communities manage resources better and improve their livelihoods, according to analysts.

The app was developed by the Indian School of Business (ISB) to track community rights in India, where the 2006 Forest Rights Act aimed to improve the lives of rural people by recognizing their entitlement to inhabit and live off forests.

With a smartphone or tablet, the app can be used to track the status of a community rights claim.

After the claim is approved, community members can use it to collect data on tree cover, burned areas and other changes in the forest and analyze it, said Arvind Khare at Washington D.C.-based advocacy Rights and Resources Initiative (RRI).

“Even in areas that have made great progress in awarding rights, it is very hard to track the socio-ecological impact of the rights on the community,” said Khare, a senior director at RRI, which is testing the app in India.

“Recording the data and analyzing it can tell you which resources need better management, so that these are not used haphazardly, but in a manner that benefits them most,” he told the Thomson Reuters Foundation.

For example, community members can record data on forest products they use such as leaves, flowers, wood and sap, making it easier to ensure that they are not over-exploited, he said.

While indigenous and local communities own more than half the world’s land under customary rights, they have secure legal rights to only 10 percent, according to RRI.

Governments maintain legal and administrative authority over more than two-thirds of global forest area, giving limited access for local communities.

In India, under the 2006 law, at least 150 million people could have their rights recognized to about 40 million hectares (154,400 sq miles) of forest land.

But rights to only 3 percent of land have been granted, with states largely rejecting community claims, campaigners say.

While the app is being tested in India, Khare said it can also be used in countries including Peru, Mali, Liberia and Indonesia, where RRI supports rural communities in scaling up forest rights claims.

Data can be entered offline on the app, and then uploaded to the server when the device is connected to the internet. Data is stored in the cloud and accessible to anyone, said Ashwini Chhatre, an associate professor at ISB.

“All this while local communities have been fighting simply for the right to live in the forest and use its resources. Now, they can use data to truly benefit from it,” he said.
