US Agency Names 4 Firms to Build Border Wall Prototypes

U.S. Customs and Border Protection selected four construction companies Thursday to erect prototypes of the Mexican border wall that President Donald Trump has said he intends to build to deter illegal immigration and smuggling. The four firms, from four different U.S. states, are to build solid-concrete prototypes of the border wall within 30 days, once they are given a notice to proceed. Those four sample walls will then be tested for strength and “permeability,” according to the agency’s acting deputy commissioner, Ronald Vitiello. The border protection agency is separately screening applicants for other contracts to build prototype walls made from alternate materials. Trump has said he thinks the 10-meter-tall wall should have windows, or even be fully transparent, so Border Patrol officers in the United States can observe suspicious activities on the other side of the barrier. “We’re going to use all the things that we think will work the best,” Vitiello said. Thursday’s announcement was the latest step forward in a bureaucratic process that has been delayed multiple times. The administration once said construction of the full border wall would begin in June, but it was not until mid-March that the first requests for proposals went out to contractors, seeking conceptual designs for the border barrier, which has been shrouded in political controversy. Congress has appropriated $20 million to CBP for use in preparing the prototypes, both of concrete and other materials. No funds have yet been budgeted for the full border wall, likely a multibillion-dollar undertaking that would …

French Labor Reform Gives Firms Flexibility

The French government said on Thursday it would cap unfair dismissal payouts and give companies more flexibility to adapt pay and working hours to market conditions in a labor reform France’s biggest union said was disappointing. The reform, President Emmanuel Macron’s first major policy step since his election in May, is also the first big test of his plans to reform the euro zone’s second-biggest economy. For decades governments of the left and right have tried to reform France’s strict labor rules, but have always diluted them in the face of street protests. The government said in a document presenting the reform that it will make it possible to adapt work time, remuneration and workplace mobility to market conditions based on agreements reached by simplified majority between employers and workers. Workers compensation for dismissal judged in a labor court to be unfair would be set at three months of wages for two-years in the company with the amount rising progressively depending on how long a worker was with the firm, unions said. However, normal severance pay would be increased from 20 percent of wages for each year in a company to 25 percent, Liberation reported. The government consulted with unions for weeks as it drafted the reform, and only the hardline CGT union, the country’s second biggest, said from the start that it would hold a protest, set for Sept. 12. France’s biggest union, the reformist CFDT, said that it would not call a strike against the reform but described …

Studying Black Holes in a Bathtub

Mysterious black holes, thought to reside in the center of every galaxy, are difficult to study because even the closest one, in the center of our own Milky Way, is still some 27,000 light years away. But researchers at the University of Nottingham’s Quantum Gravity Laboratory have found that some of the physical phenomena linked to black holes can be studied in an ordinary bathtub. VOA’s George Putic has more. …

Trump’s Immigrant Crackdown Could Slow Houston Rebuilding

In the coming weeks, as Houston turns its attention to rebuilding areas devastated by Tropical Storm Harvey, people like Jay De Leon are likely to play an outsized role — if they stay around. De Leon, 47, owns a small construction business in Houston, and he and his 10 employees do exactly the kind of demolition and refurbishing the city will need. But like a large number of construction workers in Texas, De Leon and most of his workers live in the United States illegally, and that could make things complicated. The Pew Research Center estimated last year that 28 percent of Texas’s construction workforce is undocumented, while other studies have put the number as high as 50 percent. Construction employed 23 percent of working undocumented adults in Texas at the end of 2014, higher than any other sector, according to the Migration Policy Institute. Undocumented immigrants nervous However, undocumented immigrants are growing increasingly nervous in Texas because of an immigration crackdown by the Trump administration that has cast a wide net. In addition, a new Texas law that would have taken effect later this week bars cities from embracing so-called sanctuary policies, where they offer safe harbor to illegal immigrants, and allows local police to inquire about a person’s immigration status. A federal judge Wednesday temporarily blocked most of the law from taking effect. De Leon, who has lived in the country for 20 years and has two citizen children, says the changes have spooked the city’s migrant workforce. …

Michigan, North Dakota Among States Likely to be Hurt by NAFTA Changes

Michigan is likely to be the state most hurt by changes to the NAFTA trade agreement, according to a Fitch Ratings report released Wednesday, as U.S. President Donald Trump renewed threats to scrap the deal. Trump has threatened three times in the past week to abandon the North American Free Trade Agreement, revisiting his view that the United States would probably have to start the process of exiting the accord to reach a fair deal for his country. A second round of talks starts Friday in Mexico City to renegotiate the 1994 accord binding the United States, Mexico and Canada. Business groups have largely praised NAFTA and hope to persuade all three governments to make minimal changes to the pact. U.S.-Canada-Mexico trade has quadrupled since NAFTA took effect in 1994, surpassing $1 trillion in 2015. Michigan’s auto sector While several other states export a significant amount of products to Canada and Mexico, Michigan is an outlier in Fitch’s analysis because of the state’s global role in the automotive sector and proximity to Canada, the report said. Sixty-five percent of the Michigan’s exports went to Canada and Mexico in 2016, totaling 7.4 percent of its gross state product, it said. “Any state that is particularly export dependent or exposed to trade, if there’s a falloff in trade it’s going to hit income and sales taxes and that’s going to weaken state revenues,” said Michael D’Arcy, a director of U.S. public finance at Fitch. “Cuts would have to be made.” Anna Heaton, …

US-funded Ethiopian Abattoir Hopes to Help Herders During Drought

An abattoir located among herding communities in Ethiopia’s eastern Somali region, known more for droughts and famine than business opportunities, is an unusual stop for a U.S. aid administrator. But USAID chief Mark Green stopped at the Jijiga Export Slaughter House (JESH) during a visit to the town of Jijiga on Wednesday to see the effects of a crippling drought that has pushed some areas to the south to the brink of famine. The abattoir buys goats, sheep, cows and camels for slaughter from herders for export to the Middle East, giving families cash to buy food during the drought. A $1.5-million loan from Feed the Future, a $1 billion-a-year agricultural program launched during U.S. President Barack Obama’s presidency in 2010, helped purchase refrigerators and trucks for the facility, which employs 100 people from local villages. To Green, the slaughterhouse represents what USAID can do to help attract private-sector money into investments that boost the productivity of small farmers in developing countries. While at the abattoir, Green announced 12 countries that will benefit from Feed The Future investments in 2017, signaling that the program will survive proposed deep cuts to USAID’s budget this year. The 12 countries are Bangladesh, Ethiopia, Ghana, Guatemala, Honduras, Kenya, Mali, Nepal, Niger, Nigeria, Senegal and Uganda. Green said investments like the Jijinga slaughterhouse not only created markets for American businesses but helped communities out of poverty. Herders can earn as much as $80 per goat when they sell to the slaughterhouse. “I’m under no illusions; …

Growing Commerce With India Gives Vietnam New Defense Against China

A flood of Indian business in fast-growing Vietnam has solidified commercial ties to help Hanoi upgrade an alliance with a powerful Asian neighbor and offset dependence on its historic rival, the more massive China. Indian investment in Vietnam has reached $2 billion and bilateral trade hit $10 billion over the year ending in March on its way to $15 billion by 2020, said Radha Krishnan, vice chairman of the Indian Business Chamber of Vietnam. “As of now that is very easily achievable,” Krishnan said. “The last three … years exports from Vietnam to India have picked up momentum.” Vietnam has many trade partners Last year the two countries agreed to upgrade a “strategic partnership,” giving Vietnam more Indian market access, and they will drop import tariffs in 2022 as part of a trade deal with a bloc of Southeast Asian countries. Those totals hardly match those of Vietnam’s long-time investment sources such as Taiwan, South Korea and China. But their growth offers Vietnam a line to the world’s second-largest country, helping to reduce dependence on China, which is the world’s second-largest economy and Vietnam’s biggest trading partner. China-Vietnam set a trade target of $100 billion in 2016, but the pair disputes a swathe of the South China Sea. Their dispute sparked clashes in 1974, 1988 and 2014. “The Vietnamese government, they don’t want to get an unbalanced investment portfolio where any particular country or region is dominant, because then it just unbalances everything else — foreign policy, domestic politics and everything,” …

‘Reprogrammed’ Stem Cells Fight Parkinson’s Disease in Monkeys

Scientists have successfully used “reprogrammed” stem cells to restore functioning brain cells in monkeys, raising hopes the technique could be used in the future to help patients with Parkinson’s disease. Since Parkinson’s is caused by a lack of dopamine made by brain cells, researchers have long hoped to use stem cells to restore normal production of the neurotransmitter chemical. Now, for the first time, Japanese researchers have shown that human induced pluripotent stem cells (iPS) can be administered safely and effectively to treat primates with symptoms of the debilitating disease. So-called iPS cells are made by removing mature cells from an individual — often from the skin — and reprogramming them to behave like embryonic stem cells. They can then be coaxed into dopamine-producing brain cells. The scientists from Kyoto University, a world-leader in iPS technology, said their experiment indicated that this approach could potentially be used for the clinical treatment of human patients with Parkinson’s. In addition to boosting dopamine production, the tests showed improved movement in affected monkeys and no tumors in their brains for at least two years. The human iPS cells used in the experiment worked whether they came from healthy individuals or Parkinson’s disease patients, the Japanese team reported in the journal Nature on Wednesday. “This is extremely promising research demonstrating that a safe and highly effective cell therapy for Parkinson’s can be produced in the lab,” said Tilo Kunath of the MRC Center for Regenerative Medicine, University of Edinburgh, who was not involved in …

Dream Chaser Spacecraft in Captive-carry Test Over Desert

A test version of a spacecraft resembling a mini space shuttle was carried aloft over the Mojave Desert by a helicopter Wednesday in a precursor to a free flight in which it will be released to autonomously land on a runway as it would in a return from orbit.   Sierra Nevada Corp.’s Dream Chaser craft was lifted off the ground at 7:21 a.m., at NASA’s Armstrong Flight Research Center on Edwards Air Force Base, California, and was carried to the same altitude and flight conditions it will experience before release in a free flight.   A control team sent commands to the wingless vehicle and collected data before the helicopter brought it down at 9:02 a.m., the company said.   “Everything we have seen points to a successful test with useful data for the next round of testing,” director of flight operations Lee “Bru” Archambault said in a statement.   A second captive-carry test is scheduled this year and if it is successful, a free flight test will follow.   The Dream Chaser is being developed to carry cargo to and from the International Space Station without a crew aboard. The version flown Wednesday is for tests in the atmosphere. The version that will be launched into space is still in development.   With the addition of life-support equipment, a Dream Chaser could transport a crew of seven.   Last month, Sierra Nevada selected United Launch Alliance’s Atlas 5 rocket to launch the first two Dream Chaser cargo missions, …

Famed T. rex ‘Sue’ Will Get New Look at Chicago’s Field Museum

The world’s biggest T. rex is getting ready for a cutting-edge makeover. The Field Museum in Chicago said Wednesday that it would take down and remount the 40½-foot-long (12.3-meter) Tyrannosaurus nicknamed Sue, perhaps the world’s most famous dinosaur fossil, in a way that embodies the latest understanding of this ferocious Cretaceous Period predator. The big T. rex will move to a new exhibition space in the museum, while a cast of the skeleton of the largest-known dinosaur, Patagotitan mayorum, will take the spot Sue now occupies in the museum’s Stanley Field Hall. Patagotitan, a long-necked, four-legged plant-eater that was 122 feet (37.2 meters) long and weighed 70 tons, lived in Argentina 100 million years ago, more than 30 million years before T. rex stalked western North America. The biggest land animal on record, it was a member of a dinosaur group called titanosaurs. The museum next spring will unveil the fiberglass Patagotitan skeleton, which is being cast from fossils of seven Patagotitan individuals, and for two years will display some of the genuine fossils, including an 8-foot (2.4-meter) thighbone. Named for the woman who discovered the fossils in South Dakota in 1990, Sue is the largest, most complete and best-preserved Tyrannosaurus rex ever unearthed. The museum bought the fossils at auction for $8.4 million. Sue will be taken down in February and put up again with noteworthy changes in anatomy and stance in its new exhibition hall in spring 2019, museum scientists said. “We are making several adjustments to the …

US Economic Growth Upgraded to 3 Percent Rate in Q2

The U.S. economy rebounded sharply in the spring, growing at the fastest pace in more than two years amid brisk consumer spending on autos and other goods.   The gross domestic product, the broadest measure of economic health, grew at an annual rate of 3 percent in the April-June quarter, the Commerce Department reported Wednesday. It was the best showing since a 3.2 percent gain in the first quarter of 2015.   The result is a healthy upward revision from the government’s initial estimate of 2.6 percent growth in the second quarter. The growth rate in the January-March quarter was a lackluster 1.2 percent.   Improvements in consumer spending, particularly on autos, and business investment powered second-quarter growth. Those revisions offset a bigger drag from spending by state and local governments. This was the second of three estimates the government will provide for second quarter growth. Even with the upward revision, the weak start to the year means that growth over the past six months has averaged 2.1 percent, the same modest pace seen for the recovery that began in mid-2009.   During last year’s presidential campaign, Donald Trump attacked the Obama administration’s economic record, pledging to double GDP growth to 4 percent or better. His first budget, sent to Congress earlier this year, projects growth rates will climb to a sustained annual rate of 3 percent, a goal that many private economists believe is still too optimistic.  The nonpartisan Congressional Budget Office sees growth averaging 1.9 percent over the …

Source: US Sanctions on Venezuela Oil Company CFO Tangle Financial Deals

U.S. sanctions on the finance boss of Venezuela’s oil company PDVSA have led to some exports to the United States being blocked as banks and investment funds refuse to provide letters of credit to potential buyers, three financial sources said. U.S. businesses are barred from dealing with a sanctioned person or company and one of the sources said the sanctions on PDVSA’s Finance Vice President Simon Zerpa were deterring some businesses from investments with the company as so many of its transactions are linked to the finance department he leads. A Venezuelan oil shipment to the United States was blocked this month as lenders refused to provide letters of credit to PDVSA customers, the sources said. Letters of credit, issued by banks, guarantee to a seller that a buyer will pay a specified amount on time when a shipment is accepted. Without a letter of credit, shipments cannot be delivered and the shipper does not get paid. Blocking letters of credit for PDVSA oil chokes off cash that is desperately needed in the OPEC nation. Petróleos de Venezuela, S.A., commonly known as PDVSA, is the financial motor of President Nicolas Maduro’s leftist government, and it is operating within one of the deepest economic recessions Venezuela has ever experienced and widespread political unrest. In one instance, U.S. refiner PBF Energy was unable to get a letter of credit for a Venezuelan crude cargo to be received at a U.S. port. The Suezmax tanker Karvounis has been anchored in the U.S. Gulf …

Trump to Promote Tax Reform

U.S. President Donald Trump is traveling to the state of Missouri to try to build support for his goal of reforming the country’s tax code. Administration officials say the president will focus on explaining the need for tax reform, but not the specifics of a plan to do so, during a speech Wednesday in the city of Springfield.  They say he will promote tax cuts as a way to help American workers. Trump has in the past proposed cutting the corporate tax rate from 35 percent to 15 percent. The U.S. tax code has not undergone a significant overhaul since 1986. Trump’s Republican Party controls both houses of the U.S. Congress, but failed in its earlier efforts to overhaul another major program as leaders were unable to get enough votes to change the health care system. …

Study: Cities and Companies Team Up to Tackle Urban Water Crises

With rising urban populations and ever scarcer water supplies, cities and companies are teaming up to invest billions of dollars in water management projects, a report said on Tuesday. Around two thirds of cities from London to Los Angeles are working with the private sector to address water and climate change stresses with 80 cities seeking $9.5 billion of investment for water projects, according to a report by the Carbon Disclosure Project (CDP), a non-profit environmental research group. Water investment opportunities are greatest in Latin America, with Quito in Ecuador seeking $800 million to manage its water supply, including building three hydropower stations and cleaning up its contaminated rivers and streams. City in India prepares for future The cities most concerned about their water supply lie in Asia and the Pacific, the report found, with serious risks also identified in Africa and Latin America. The key issues for cities include declining water quality, water shortages and flooding. The Indian city of Chennai faced extreme floods in 2015 which killed hundreds and left survivors without access to clean water, while businesses were also severely disrupted. The city is now investing in boosting its resilience to future water crises, with water conservation education, building a storm water management system and new infrastructure. “We are seeing critical shifts in leadership from cities and companies in response to the very real threat of flooding, for example, to local economies,” said Morgan Gillespy, head of CDP’s Water Program. Climate change is another underlying threat to …

Climate to Push Forest-eating Beetles to Northern US, Canada, Scientists Predict

Forests in the northeastern United States and southern Canada could be ravaged by tree-killing beetles in coming decades as a warming climate expands the pest’s habitat, a study has found. Over the next 60 years, southern pine beetles could infest forests in new areas of the United States and Canada, disrupting industries and ecosystems alike, it said. Warmer winter nights allow spread The red-brown insects, the size of a grain of rice, known to feast on pine-tree bark, has typically only thrived in the hotter climate of Central America and the southeastern United States. But in recent years warmer than usual winter nights have allowed it to survive the cold months and spread as far north as the U.S. state of New York. The coldest winter night has warmed by 6 to 7 degrees Fahrenheit (3 to 4 degrees Celsius) over the past 50 years in various parts of the United States, the study’s authors said. Using computer-based climate models, they predicted the beetles should gradually march north along the Atlantic coast, infesting forests including in the U.S. states of Maine and Ohio all the way to Canada’s Nova Scotia. Pest moves fast By 2080, the pest should proliferate to red — and jack-pine forests in a 270,000 square miles (700,000 square km) area of the United States and Canada — roughly the size of Afghanistan, the researchers wrote in Nature Climate Change. That would not only upend ecosystems, but also disrupt several key industries “in already struggling rural areas,” …

US Spacecraft Readies for Fiery Plunge into Saturn After 13-year Mission

The U.S. space agency’s Cassini spacecraft will end its 13-year mission to Saturn in mid-September by transmitting data until the final moment before it plunges into the ringed planet’s atmosphere, officials said Tuesday. Cassini, the first spacecraft to orbit Saturn, will make the last of 22 farewell dives between the planet’s rings and surface on Sept. 15. The spacecraft will then burn up as it heads straight into the gas giant’s crushing atmosphere. Cassini’s final dive will end a mission that provided groundbreaking discoveries that included seasonal changes on Saturn, the moon Titan’s resemblance to a primordial Earth, and a global ocean on the moon Enceladus with ice plumes spouting from its surface. “The mission has been insanely, wildly, beautifully successful, and it’s coming to an end in about two weeks,” Curt Niebur, Cassini program scientist, said on a telephone conference call with reporters from NASA’s Jet Propulsion Laboratory in California. Cassini’s final photo as it heads into Saturn’s atmosphere will likely be of propellers, or gaps in the rings caused by moonlets, said project scientist Linda Spilker. The spacecraft will provide near real-time data on the atmosphere until it loses contact with Earth at 4:54 a.m. PDT (1154 GMT) on Sept. 15, the National Aeronautics and Space Administration said. Spilker said Cassini’s latest data on the rings had shown they had a lighter mass than forecast. That suggests they are younger than expected, at about 120 million years, and thus were created after the birth of the solar system, …

World Bank: Tackle Middle East Water Scarcity to Save Money, Boost Stability

The Middle East and North Africa region loses about $21 billion each year because of an inadequate supply of water and sanitation, the World Bank said Tuesday, warning that urgent action is needed to prevent ripple effects on stability and growth. Poor management of water resources and sanitation in the world’s most water-scarce region costs about 1 percent of its annual gross domestic product, with conflict-hit states losing as much as 2 to 4 percent each year, the bank said in a report issued at the World Water Week conference in Stockholm, Sweden. Deaths due to unsafe water and sanitation in some parts of the region, particularly countries affected by conflict, are higher than the global average, it added. “As the current conflict and migration crisis unfolding in the Middle East and North Africa shows, failure to address water challenges can have severe impacts on people’s well-being and political stability,” the report said. Peril in Yemen In Yemen, which is reeling from more than two years of conflict, water supply networks serving its largest cities are at risk of collapse due to war-inflicted damage and disrepair, and about 15 million people have been cut off from regular access to water and sanitation, the U.N. children’s agency (UNICEF) said in a separate statement Tuesday. In Syria, where the conflict is well into its seventh year, water has frequently been used as “a weapon of war,” with pumps deliberately destroyed and water sources contaminated, and about 15 million people are in need …

Mexico Dusts Off ‘Plan B’ as Trump Revs Up Threats to Kill NAFTA

Mexico sees a serious risk the United States will withdraw from NAFTA and is preparing a plan for that eventuality, Economy Minister Ildefonso Guajardo said Tuesday, calling talks to renegotiate the deal a “roller coaster.” U.S. President Donald Trump has threatened three times in the past week to abandon the North American Free Trade Agreement, revisiting his view that the United States would probably have to start the process of exiting the accord to reach a fair deal for his country. Trump has vowed to get a better deal for American workers, and the lively rhetoric on both sides precedes a second round of talks starting on Friday in Mexico City to renegotiate the 1994 accord binding the United States, Mexico and Canada. “This is not going to be easy,” Guajardo said at a meeting with senators in Mexico City. “The start of the talks is like a roller coaster.” The need for a backup plan in case Trump shreds the deal underpinning a trillion dollars in annual trade in North America has been a long-standing position of Guajardo, who travels to Washington on Tuesday with foreign minister Luis Videgaray to meet senior White House and trade officials. “We are also analyzing a scenario with no NAFTA,” Guajardo said. In an interview published earlier on Tuesday in Mexican business daily El Economista, Guajardo said “there is a risk, and it’s high” that the Trump administration abandons NAFTA. Responding to Guajardo’s comments, Canadian Prime Minister Justin Trudeau said his government would …

Brazil Looks to China to Finish Nuclear Power Plant

Brazil will seek China’s expertise and financing to complete its third nuclear power plant when President Michel Temer makes a state visit to Beijing on Friday, Brazilian government officials said Tuesday. The Brazilian nuclear energy company Eletronuclear will sign a cooperation agreement with China National Nuclear Corporation (CNNC), signaling their intent to establish a partnership to finish the Angra 3 plant, the officials said. Construction of the 1,405-megawatt reactor on the coast south of Rio de Janeiro has dragged on for three decades and its completion is now scheduled for 2023, but Brazil does not have the estimated 16 billion reais ($5 billion) needed to finish the job. Russia is also interested in completing Angra 3 and Eletronuclear, a subsidiary of state-run electric utility Eletrobras, has held talks with the Russian nuclear monopoly Rosatom. The Chinese corporation is expected to have the advantage in terms of abundant financial resources. The head of Eletronuclear, Bruno Barretto, signed an initial memorandum with CNNC on the Angra 3 completion in Beijing in December when he visited Chinese banks that are potential financiers, Eletronuclear said in a statement. Temer’s government has announced plans to privatize Eletrobras, Latin America’s largest utility. But Eletronuclear will be split off and remain in state hands under Brazil’s Constitution, which establishes that nuclear facilities must be government controlled. Temer said on Tuesday he expects China to be a major player in Brazil’s plans to modernize its ports, airports and other infrastructure projects that will be offered to investors in …

Syrian Schools Grow Edible Playgrounds to Boost Diets of Hungry Children

School playgrounds across Syria are being transformed into vegetable gardens where children whose diets have been devastated by six years of war can learn to grow — and then eat — aubergines, lettuces, peppers, cabbages and cucumbers. Traditional Syrian cuisine is typical of the region, and rich in vegetables. Its mainstays include hummus, minced lamb cooked with pine nuts and spices, varied salads, stews made with green beans, okra or courgettes and tomatoes, stuffed cabbage leaves and artichoke hearts. But the six-year war has changed that for much of the population, and many now live mainly on bread or food aid. According to U.N. figures, unemployment now stands at more than 50 percent, and nearly 70 percent of the population is living in extreme poverty, in what was once a relatively wealthy country. “The ongoing crisis in Syria is having a devastating effect on the health and nutrition of an entire generation of children,” Adam Yao, the U.N. Food and Agriculture Organization’s (FAO) acting representative in Syria, said on Tuesday, ahead of the start of the school year. FAO is helping some 17 primary schools in both government and opposition-controlled areas to plant up to 500 meter-square fruit and vegetable plots in war-torn areas including Aleppo, Hama, Homs, Idlib and the outskirts of Damascus. Young children are often the most vulnerable to malnutrition in a crisis, which can have serious and long-lasting effects on their growth and future development. “Good nutrition is a child’s first defense against common diseases and …
