SpaceX’s chief said Wednesday that the first launch of its big new rocket is risky and stands “a real good chance” of failure. Founder Elon Musk told a space station research conference Wednesday that he wants to set realistic expectations for the flight later this year from Cape Canaveral. The Falcon Heavy will have three boosters instead of one, and 27 engines instead of nine, all of which must ignite simultaneously. No one will be aboard the initial flights. When it comes time to add people, Musk said, “no question, whoever’s on the first flight, brave.” SpaceX plans to fly two paying customers to the moon late next year, using a Falcon Heavy. While the moon may not be in Musk’s personal travel plans, he said in response to a question that he’d like to ride one of his smaller Falcon rockets to the International Space Station in maybe three or four years. SpaceX plans to start ferrying NASA astronauts to the orbiting outpost, using Falcon 9 rockets and enhanced Dragon capsules, by the middle of next year. SpaceX now uses the Dragon capsule to deliver supplies to the space station. “All right, we’ll put you on the manifest,” said NASA’s space station program manager Kirk Shireman. ’Major pucker factor’ Speaking for over an hour at the Washington conference, Musk encouraged people to go to Cape Canaveral for the Falcon Heavy launch. “It’s guaranteed to be exciting,” he promised, getting a big laugh. “There’s a lot of risk associated with …
Amazon Launches Shopping Social Network Spark for iOS
Amazon.com has launched a social feature called Spark that allows members to showcase and purchase products on its platforms, the retail giant’s first clear move into the world of social media. Spark, which is currently only available for Amazon’s premium paying Prime members, encourages users to share photos and videos, just like popular social media platforms Instagram and Pinterest. The new feature publicly launched on Tuesday for use on mobile devices that use Apple’s iOS operating system. Spark users can tag products on their posts that are available on Amazon and anyone browsing the feeds can instantly find and purchase them on the platform. Users can also respond to posts with “smiles,” equivalent to Facebook’s “likes.” “We created Spark to allow customers to discover – and shop – stories and ideas from a community that likes what they like,” said an Amazon spokeswoman. “When customers first visit Spark, they select at least five interests they’d like to follow and we’ll create a feed of relevant content contributed by others. Customers shop their feed by tapping on product links or photos with the shopping bag icon.” Amazon has also invited publishers including paid influencers and bloggers to post on Spark. Their posts are identified with a sponsored hashtag. Many Amazon users on social media called the service a cross between Instagram and Pinterest with a touch of e-commerce. Brand strategist Jill Richardson (@jillfran8) said: “Been messing with #AmazonSpark all morning and I am LIVING. It’s like Pinterest, Instagram, and my credit …
Понад 40 тисяч людей на Луганщині залишаються без води через знеструмлення водоканалів – Гарбуз
Голова військово-цивільної адміністрації Луганщини Юрій Гарбуз заявив про надзвичайну ситуацію з енергозабезпеченням, що склалася в області. «Унаслідок знеструмлення водоканалів без питної води залишились понад 40 тисяч осіб та 30 об’єктів соціальної інфраструктури, у тому числі дитяча обласна лікарня. Питання роботи «ЛЕО» (Луганське енергетичне об’єднання – ред.) укотре мною виноситься на рівень Кабінету міністрів», – написав Гарбуз у Facebook. Насосні станції Лисичанського і Попаснянського водоканалів на Луганщині «ЛЕО» почало знеструмлювати через борги, через що у Сєвєродонецьку відбувались акції протесту. Повідомлялось про знеструмлення не тільки цивільних об’єктів, але й військових. У військово-цивільній адміністрації Луганщини пропонують передати Луганське енергетичне об’єднання в управління держави. В окремі населені пункти воду вирішили підвозити силами ДСНС. …
Насалик: Вугілля з непідконтрольної Україні частини Донбасу може потрапляти до Туреччини
Вугілля із непідконтрольної Україні частини Донецької та Луганської областей, ймовірно може реалізуватися у Туреччині, сказав журналістам міністр енергетики Ігор Насалик після засідання уряду. «Міністерство звернулось до восьми посольств, де, можливо, могло би реалізовуватися вугілля із зони АТО. Зараз найбільш проблематичною такою точкою є Туреччина», – зазначив міністр. За його даними, наразі ведеться робота із українським посольством у Туреччини, щоб припинити таку практику. Станом на травень 2017 року всі шахти, на яких видобувають антрацит, на окупованій частині Донбасу, в тому числі ті, що раніше працювали у правовому полі України і постачали антрацит на вільну територію країни, були повністю захоплені сепаратистами. Власники шахт – у першу чергу енергохолдинг ДТЕК, підконтрольний українському підприємцеві Рінатові Ахметову, – попереджали про незаконність можливого експорту викраденого на цих шахтах вугілля. 15 березня компанії ДТЕК і «Метінвест», підконтрольні Ахметову, заявили про повну втрату контролю над своїми підприємствами на окупованій території Донбасу, які до захоплення працювали у правовому полі України. Угруповання «ДНР» і «ЛНР», підтримувані Росією, заявили тоді, що запровадили «зовнішнє управління» на всіх підприємствах української юрисдикції, які працювали на територіях, захоплених цими угрупованнями, – на знак протесту проти блокади активістами торгівлі з непідконтрольною територією. За повідомленнями, ці підприємства фактично перейшли під російський контроль. Російські митні органи у своїй статистиці за 2017 рік повідомили, що з України останнім часом ввозили вугілля антрацитової групи, яке видобувається тільки на окупованій частині Донбасу, на шахтах, незаконно захоплених сепаратистами, а також продавали антрацит до України. За статистичними даними Південного митного управління Федеральної служби Росії, які наведені на його сайті (останні зміни в документі датовані вівторком, …
Asia’s Richest Man Comes Under Pressure in China
Asia’s richest man, Wang Jianlin, suddenly finds himself cornered. The giant Dalian Wanda Group, which he heads, is facing a range of regulatory investigations and actions from the Chinese authorities. The latest move involves asking banks to stop financing overseas forays of the Wanda Group, which owns an array of foreign assets, including a Hollywood studio and AMC Theaters, the biggest exhibitor of movies in the U.S. The Group faced a regulatory probe into its financial deals in early June, which was followed by an announcement that Wanda had sold off part of its business to a Tianjin based real estate developer for $9.3 billion. The government action against a businessman known for his strong connections with the Communist Party has caused a stir in the business community, with many asking if the government is sending out a political message to all privately owned businesses, informed sources said. Role of politics “That is a surprising development in a lot of different ways. Wang Jianlin has many friends all through the political establishment in China,” said Christopher Balding, an associate professor of finance and economics at Peking University HSBC Business School. The industry in China is debating about whether the Wanda Group has been hit by a policy measure or Wang has fallen from the grace of the political establishment. “I don’t think this [action] is particularly targeting Mr. Wang, the chairman of Wanda Group, or purposefully targeting the Wanda group,” said Peng Liu, professor of real estate and hotel management at the Cornell University. “Actually, those [moves] are in line with the …
Uber-style App ‘Careem’ Goes Off Beaten Track in Palestinian West Bank
Careem, a Middle Eastern rival to Uber, has become the first ride-hailing firm to operate in the Israeli-occupied West Bank. Dubai-based Careem, whose name is a play on the Arabic word for generous or noble, launched in Ramallah in June, aiming to bring digital simplicity to the Palestinian territory. There is certainly a market for easier ride-hailing among the nearly 3 million Palestinians living in the West Bank, but the fact the mobile network is still 2G, that electronic payments are not the norm and that Israeli checkpoints are common, make using the service somewhat cumbersome. Yet Careem is optimistic about the potential. “We are planning to invest hundreds of thousands of dollars within the coming year in the (Palestinian) sector,” Kareem Zinaty, operations manager for the Levant region said. “After the investment, it is also an opportunity to create jobs.” Careem, which launched in 2012 and now operates in 12 countries and more than 80 cities across the Middle East, Africa, and South Asia, has said it aims to provide work for one million people across the region by 2018. Careem’s captains While a version of Uber and Israeli app Gett already operate in Israel, they do not venture into Palestinian territory. Drivers are excited to work with Careem, which they hope will help boost their incomes, especially with unemployment in the West Bank running at nearly 20 percent. “It’s a very wonderful opportunity,” said one of the more than 100 new drivers, known as “captains” by Careem. “Most …
Measles Kills 35 Children in Europe; Minnesota Outbreak Not Over
Thirty-five European children have died from measles in the past 12 months in what the World Health Organization calls an “unacceptable” tragedy. The deaths could have been prevented by a vaccine. A measles outbreak in Minnesota sent many to the hospital. Still, some parents in developed countries continue to believe false reports that the measles vaccine causes autism. Some parents are refusing to get their children vaccinated for other diseases as well. VOA’s Carol Pearson reports. …
Native American Healing Class Sparks Unique Health Textbook
Laughter can combat trauma. Spiritual cleansings could be used to fight an opioid addiction. Cactus extract may battle diabetes and obesity. These insights are from curanderismo — traditional indigenous healing from the American Southwest and Latin America. University of New Mexico professor Eliseo “Cheo” Torres’ has included these thoughts in a new, unique textbook connected to his internationally-known annual course on curanderismo. “Curanderismo: The Art of Traditional Medicine Without Borders,” released last week, coincides with Torres’ annual gathering of curandero students and healers around the world at the University of New Mexico. For nearly 20 years, healers and their students have come to Albuquerque to meet and exchange ideas on traditional healing that for many years were often ignored and ridiculed. Torres, who is also the university’s vice president for student affairs, said the popularity of the annual course and a similar online class he teaches convinced him that there needed to be a textbook on curanderismo. “This textbook came out of the experience of this class and the ideas that have been shared through the years,” Torres said during a special morning ceremony with Aztec dancers on campus. “From healers in Mexico to those in Africa, many have long traditions of healing that are being rediscovered by a new generation.” Curanderismo is the art of using traditional healing methods like herbs and plants to treat various ailments. Long practiced in Native American villages of Mexico and other parts of Latin America, curanderos also …
Peru Cancels Plan to Cut Value-Added Tax Rate as Growth Slows
The government of Peru’s President Pedro Pablo Kuczynski is no longer considering cutting the value-added tax (VAT) rate due to slumping government revenues as the economy slows, the country’s prime minister said Tuesday. Trimming the VAT rate gradually to 15 percent from 18 percent had been part of Kuczynski’s economic platform as he took office a year ago, before severe flooding and a graft scandal thwarted investments and knocked Peru’s growth outlook. Dropping the plan will likely be welcomed by the right-wing opposition that had feared a VAT reduction would widen the fiscal deficit. But it could be seen as a broken campaign promise by Kuczynski allies who expected a lower rate to stimulate the economy and encourage more people to pay the tax. “Reducing the VAT has been ruled out,” Prime Minister Fernando Zavala told foreign media in a press conference. “Tax revenues haven’t grown in recent months and we think we have to improve that in coming years by making VAT collection more efficient.” Kuczynski named Zavala finance minister while keeping him in his post as prime minister last month after the opposition-controlled Congress ousted the former finance minister over a scandal involving an airport contract. Peru, the world’s second biggest copper, zinc and silver producer, has enjoyed some of the strongest growth readings and slowest inflation rates in the region this century. But the economy will likely slow to 2.8 percent this year from 3.9 percent in 2016, even with the government’s planned fiscal stimulus, Zavala said. …
Brazil’s Temer Eyes Minor Tax Reform as Pension Overhaul Stalls
With corruption charges delaying his unpopular proposal for the overhaul of Brazil’s costly pension system, President Michel Temer is trying to quickly push through a mini tax reform, a presidential aide told Reuters on Tuesday. The simplification of the PIS/Cofins federal social security contributions levied on gross receipts would face easier passage in Congress and allow Temer to show his wavering allies that his administration is still advancing on its promised reform agenda. “There won’t be the political environment to approve pension reform until the issue of the charges is out of the way,” said the aide, who requested anonymity because he was not authorized to speak publicly on the matter. Federal prosecutors charged Temer last month with taking bribes. Though his government is confident it has the backing in Congress to stop a trial by the Supreme Court, that support could melt away if his administration is seen to be paralyzed. In a video statement released on social media on Monday, Temer said tax reform was a priority and a bill would be sent to Congress in “very little time.” He has held talks this week on the tax reform with his economic team and a series of lawmakers. Temer pointed to approval last week of a measure modernizing Brazil’s labor laws as a sign his government is still working. “We know it is difficult to pass pension reform. It is clear there is no climate for that now,” said Lucio Vieira Lima, the deputy leader of the ruling …
Trump Seeks Crackdown on ‘Made in America’ Fakes
U.S. President Donald Trump is looking for ways to defend American-made products by certifying legitimate U.S. goods and aggressively going after imported products unfairly sporting the “Made in America” label, the White House said on Tuesday. Trump, who campaigned on reviving the U.S. manufacturing sector, vowed on Monday that his administration would crack down on “predatory online sales of foreign goods” hurting U.S. retailers. On Wednesday, Trump will discuss with small- and medium-sized manufacturers how to certify their products and keep out foreign counterfeits, a senior administration official told reporters. Their products include gutter filters, flags and pillows. “There’s just too many examples of foreigners slapping on ‘Made in America’ labels to products and the worst insult is when they do it after they have actually stolen the product design,” the official said. The United States loses about $300 billion a year to theft of intellectual property ranging from semiconductors to jeans, the official said. In March, Trump signed an executive order that gave customs officials more authority to stop pirated and counterfeit items, the official told reporters. The White House plans to work with the private sector on the new certification and verification system rather than create new regulations or spend taxpayer money, the official said, citing as a model the LEED system used to rate the environmental sustainability of building projects. …
Угорщина вирішила продовжити видачу дозволів на роботу громадянам України і Сербії
Міністр економічного розвитку Угорщини Мігай Варґа повідомив, що впродовж останніх місяців громадяни України і Сербії отримали 10 500 дозволів на роботу в Угорщині. За його словами, це практикуватиметься і надалі, адже загальна квота дозволів далеко не вичерпана і становить 59 тисяч, інформує кореспондент Радіо Свобода. Варґа зазначив, що уряд Угорщини прагне запобігти втратам на виробництві. Це стосується рівною мірою не тільки місцевих підприємств, але й компаній іноземних інвесторів, уточнив міністр. Згідно з соціологічними опитуваннями, через значний відплив робочої сили з Угорщини у країни Західної Європи кожне п’яте підприємство не може заповнити вакансії кваліфікованих працівників. А початківців доводиться утримувати додатковими виплатами чи соціальними пільгами. Наразі за допомогою консалтингових компаній із США Міністерство економічного розвитку Угорщини анонсувало програму допомоги малому і середньому бізнесові з метою підбору і підготовки кваліфікованих кадрів, у тому числі з України та деяких інших країн Східної Європи, які не є членами Євросоюзу. …
Daimler to Recall 3 Million Vehicles to Ease Diesel Doubts
German automaker Daimler says it is voluntarily recalling 3 million diesel cars in Europe to improve their emissions performance. The Stuttgart-based company, which makes Mercedes-Benz luxury cars, says it is taking the step to reassure drivers and strengthen confidence in diesel technology. Diesels have been under a cloud since Daimler’s competitor Volkswagen admitted equipping vehicles with illegal software that meant they passed emissions tests, but then exceeded limits in everyday driving. There has been a push for diesel bans in some German cities because of concerns about levels of nitrogen oxide emitted by diesels. The Daimler announcement comes hours after the regional government in the company’s home region of Baden-Wuerttemburg agreed to abandon proposals to restrict diesels if older diesels could be mechanically fixed to pollute less, the dpa news agency reported. Daimler CEO Dieter Zetsche said Tuesday that “the public debate about diesel engines is creating uncertainty – especially for our customers.” The recall will cover nearly all vehicles made under the EU5 and EU6 emissions standards and start in the next few weeks. The company said it would cost 220 million euros ($254.21 million), but that customers wouldn’t pay anything. Daimler said in May that German investigators had searched its offices in connection with investigations of Daimler employees because of suspicion of fraud and criminal advertising relating to the possible manipulation of exhaust controls in cars with diesel engines. The company has said it is cooperating with the investigation. …
US-China Trade Rifts Resurface Even After Friendly Summit
Cake and conversation, it seems, can go only so far to mend longstanding economic rifts between the United States and China. Three months after President Donald Trump and his Chinese counterpart, Xi Jinping, shared chocolate cake at an amiable summit in Florida, tensions between the world’s two biggest economies are flaring again. Just as officials of the two nations prepare to meet Wednesday in Washington, the Trump administration is considering slapping tariffs on steel imports, a step that risks igniting a trade war. For the United States, it’s a perilous option to address a problem caused largely by China’s overproduction of steel. And Trump is criticizing China again for failing to use its economic leverage to rein in its neighbor and ally, the nuclear rogue state North Korea. Could this week’s U.S.-China Comprehensive Dialogue produce a meaningful breakthrough in economic relations? Most China watchers are skeptical. “I’m not looking for anything worthwhile,” says Derek Scissors, a China specialist at the conservative American Enterprise Institute. For one thing, the points of difference between the two countries run deep. For another, Xi faces political pressures at home and won’t want to cause a stir in Beijing. For all the tensions between the two nations, Trump’s words about Xi himself have remained warm. He has suggested that the personal bond he formed with Xi when the two met April 6-7 at Trump’s Mar-a-Lago resort can overcome fundamental differences on trade and national security. Last week, the president called his Chinese counterpart a “friend …
Nepalis, Saddled With Banned Indian Rupee Notes, Risk Losing Savings
Nepalis stand to lose millions of dollars held in high-value Indian bank notes that India banned last year and has yet to exchange, a Nepali central bank official said on Tuesday. Indian Prime Minister Narendra Modi in November banned 500 rupee ($7.77) and 1,000 rupee bank notes as part of a drive against unaccounted wealth in India that has also hit Nepal where Indian rupees are widely used. People holding the notes in India were given a little less than two months to exchange them at banks. In March, officials from the Reserve Bank of India (RBI) visited Nepal and promised to allow every Nepali citizen to exchange 4,500 Indian rupees ($70) worth of the old notes for new ones. “That was only a verbal assurance but no formal decision from India has come to us,” said Chinta Mani Shivakoti, a deputy governor of the central Nepal Rastra Bank. “Even if this amount was exchanged, individuals holding more than 4,500 Indian rupees risk losing the excess,” Shivakoti said. Nepal depends heavily on funds from workers in India, who sent home $640 million in 2016, or about 3 percent of its gross domestic product. The Indian central bank declined to comment. An Indian Finance Ministry spokesman also declined to comment, saying it was a central bank matter. India fears that if it agrees to Nepal’s demand to allow Nepalis to exchange unlimited amounts, a large number of Indians may launder their ill-gotten old notes through Nepal. Shivakoti said Nepal’s banks hold …
War-torn South Sudan at Grave Risk on Climate Change
“I’m addicted to cutting trees,” says Taban Ceasor. His stained hands sift through jagged pieces of charcoal in his busy shop in South Sudan’s capital. But the 29-year-old logger says the number of trees needed to fuel his trade is falling sharply as the country’s forest cover disappears. The world’s youngest nation is well into its fourth year of civil war. As South Sudan is ravaged by fighting and hunger, it also grapples with the devastating effects of climate change. Officials say the conflict is partly to blame. South Sudan’s first-ever climate change conference in June highlighted a problem for much of sub-Saharan Africa: The impoverished nations face some of the world’s harshest impacts from global warming and are the least equipped to fight back. The United States’ recent withdrawal from the Paris climate agreement hurts a huge potential source of assistance. The U.S. Embassy in South Sudan said it “does not currently support climate change efforts” in the country. The United Nations says South Sudan is at grave risk at being left behind. According to the Climate Change Vulnerability Index 2017 compiled by global risk consultancy Verisk Maplecroft, South Sudan is ranked among the world’s five most vulnerable countries and is experiencing some of the most acute temperature changes. “It’s rising 2.5 times quicker” than the global average, says Jean-Luc Stalon, senior deputy country director at the U.N. Development Program. Both U.N. and government officials call it a partially man-made crisis. …
Small US Towns Brace for Rare Solar Eclipse, and Crowds
Hyrum Johnson, mayor of the tiny city of Driggs, Idaho, expects some craziness in his one-stoplight town next month when the moon passes in front of the sun for the first total solar eclipse in the lower 48 U.S. states since 1979. The town of 1,600 people in Teton County, just west of the jagged peaks of the Rocky Mountains Teton Range, is getting poised to receive as many as 100,000 visitors on Aug. 21 for the celestial event, said Johnson, who was both excited and worried. Driggs is one of hundreds of towns and cities along a 70-mile arc, stretching from Oregon to South Carolina, that are in the direct path of the moon’s shadow. The full eclipse and the sun’s corona around the disk of the moon will be visible for a little more than two minutes only to those within this narrow band. Driggs and other towns like it are scrambling to prepare for the onslaught of curious visitors. “We expect gridlock,” Johnson, 46, said as he drove his pickup truck through town. Tucked amid seed potato and quinoa farms, Driggs normally enjoys a more languid pace of life, with highlights including $5 lime shakes sold on balmy summer days at the corner drug store. But with the impending eclipse, planning has kicked into high gear. To make sure nothing more than the roads will be clogged, Johnson took shipment this month of two massive generators that can be deployed at key spots along the city’s sewage …
House Budget Blueprint Boosts Military, Cuts Benefits
House Republicans on Tuesday unveiled a 10-year budget blueprint that would dramatically increase military spending while putting the GOP on record favoring Medicare cuts opposed by President Donald Trump. The GOP plan, authored by Budget Chairman Diane Black, R-Tenn., would also pave the way for overhauling the U.S. tax code this fall, and would pair that effort with cuts to benefit programs such as food stamps. The plan also lays out a plan to balance the budget inside a decade through deep cuts to a wide swath of domestic programs — though GOP leaders have no intention of actually carrying out the cuts. Black announced a committee vote for Wednesday, but action by the entire House could be delayed by an ongoing quarrel between the GOP’s tea party and moderate factions over spending cuts. Medicare is the second largest mandatory program after Social Security, and the House GOP plan again proposes to turn Medicare into a voucher-like program in which future retirees would receive a fixed benefit to purchase health insurance on the open market. Republicans have proposed the idea each year since taking back the House in 2011, but they’ve never tried to implement it — and that’s not going to change now, even with a Republican as president. The plan, in theory at least, promises to balance the budget through unprecedented and unworkable cuts across the budget. It calls for turning this year’s projected $700 billion or so deficit into a tiny $9 billion surplus by 2027. …
Trump Touts ‘Made in America Week’
The Trump Administration has launched “Made In America Week” to highlight the importance of U.S. manufacturing and tout its policies to bring more such jobs back home from overseas. But as VOA White House Bureau Chief Steve Herman reports, many Trump family products are made in foreign factories, leading to criticism of the president’s trade campaign. …
US Makes Lower Trade Deficit Top Priority in NAFTA Talks
The United States on Monday launched the first salvo in the renegotiation of the 23-year-old North American Free Trade Agreement (NAFTA), saying its top priority for the talks was shrinking the U.S. trade deficit with Canada and Mexico. In a much-anticipated document sent to lawmakers, U.S. Trade Representative Robert Lighthizer said he would seek to reduce the trade imbalance by improving access for U.S. goods exported to Canada and Mexico under the three-nation pact. For the first time in a U.S. trade deal, the administration also said it wants an “appropriate” provision to deter currency manipulation by trading partners. The move appeared aimed at future trade deals rather than specifically at Canada and Mexico, which are not considered currency manipulators. The 17-page document asserted that no country should manipulate its currency exchange rate to gain an unfair competitive advantage, an often-cited complaint about China in past years. Shortly before the release of the document, President Donald Trump lashed out against trade deals and unfair trade practices, saying he would take more legal and regulatory steps during the next six months to protect American manufacturers. ‘Not earth shattering’ Canadian Minister of Foreign Affairs Chrystia Freeland said the U.S. list was “part of its internal process” although a source familiar with Canadian government thinking said the document was “not earth shattering.” Trade experts have argued that shrinking the yawning U.S. trade deficit will not be achieved by revising trade deals but rather by boosting U.S. savings. “The first bullet point shows their …
Hearing is Believing: Speech May be a Clue to Mental Decline
Your speech may, um, help reveal if you’re uh … developing thinking problems. More pauses, filler words and other verbal changes might be an early sign of mental decline, which can lead to Alzheimer’s disease, a study suggests. Researchers had people describe a picture they were shown in taped sessions two years apart. Those with early-stage mild cognitive impairment slid much faster on certain verbal skills than those who didn’t develop thinking problems. “What we’ve discovered here is there are aspects of language that are affected earlier than we thought,” before or at the same time that memory problems emerge, said one study leader, Sterling Johnson of the University of Wisconsin-Madison. This was the largest study ever done of speech analysis for this purpose, and if more testing confirms its value, it might offer a simple, cheap way to help screen people for very early signs of mental decline. Don’t panic: Lots of people say “um” and have trouble quickly recalling names as they age, and that doesn’t mean trouble is on the way. “In normal aging, it’s something that may come back to you later and it’s not going to disrupt the whole conversation,” another study leader, Kimberly Mueller, explained. “The difference here is, it is more frequent in a short period,” interferes with communication and gets worse over time. The study was discussed Monday at the Alzheimer’s Association International Conference in London. About 47 million people worldwide have dementia, and Alzheimer’s …
Research Tries ‘Shock and Kill’ to Eliminate HIV
Researchers working on a one-two punch to eliminate HIV say their first punch has landed and they can start working on the second, though plenty of work will be needed on both fronts before a cure is available. HIV spreads just like other viruses: It takes over a cell’s DNA and uses the cell’s infrastructure to make copies of itself. Most HIV treatments work by blocking new cells from getting infected. The cells that are actively producing HIV are constantly being killed, either by HIV or by the immune system. So once you stop new cells from getting infected, the patient can achieve a viral load close to zero. Viral reservoir remains hidden That’s not a total cure though, because some HIV-infected cells go into a resting state, and stop actively producing the virus. This viral reservoir remains hidden from the immune system. The problem is that if treatment stops, the latent virus will eventually reactivate and the disease will be able to spread again. Doctors have gotten pretty good at stopping HIV from infecting new cells, but they still haven’t figured out how to eliminate these reservoirs, and so patients must take medication for their entire life. That’s why maintaining health care access for everyone living with HIV is a major public health challenge. And even for those who can access life-long care, over time these drugs can damage the liver, kidneys, heart and brain. ‘Shock and kill’ In 2012, a University of North Carolina research group published a proof of …
Chinese Overfishing Threatens West African Economies
Foreign fishing vessels, many from China, prowl the waters off West Africa every day. They capture millions of fish — catches that used to go to local boats. The fish are then shipped to China, Europe and the United States, satisfying a global demand for seafood and fueling a multibillion-dollar industry. The foreign vessels make life hard for West African fishermen. Foreign trawlers from Asia and Europe have cost West Africa’s economy 300,000 jobs and $2 billion in income, according to John Hocevar, a marine biologist with Greenpeace. However, what to do about the problem — and possible damage to regional fish populations — has eluded experts and officials. Chinese presence Exact numbers are difficult to come by, but experts agree no single country has a greater presence off the coast of West Africa than China. In a 2015 report, Greenpeace estimated that, two years earlier, China had 426 distant water fishing vessels off Africa’s West Coast. Between 2000 and 2011, 64 percent of China’s average annual catches, valued at more than $7 billion, came from that area, according to The Pew Charitable Trusts. Fishing isn’t a big part of China’s economy, representing less than one percent of total gross domestic product. But for many in China’s coastal provinces, it’s both a livelihood and way of life, according to Haibing Ma, the China program manager for the Worldwatch Institute, a nonprofit group that researches sustainability. Chinese fishers have traveled to Africa because their own fish stock has nearly run out. …
Communicating With Our Microbes
Charles Darwin’s theory of evolution says humans evolved as a separate species. But modern science knows that we, together with all other creatures, have always lived in a symbiosis with a great number of microbes, dwelling inside and outside of our bodies, the so-called holobiont. VOA’s George Putic spoke with a scientist who says the fact that we evolved together calls for a revision of Darwin’s view. …
