About 40% of the more than 617,000 bridges in the U.S. are at least 50 years old, and of that number more than 46,000 are in dangerously poor condition. The job of bridge inspectors is to locate and identify their structural deficiencies. Svitlana Prestynska met with one such inspector and filed this report from Denver, Colorado, narrated by Anna Rice.

New clean energy technologies like solar power and electric vehicles are expected to remake the global energy industry. Trillions of dollars used to drill and ship oil and gas will instead be spent finding and processing the specialized minerals used to make high-tech gear including advanced electric generators and powerful, compact batteries.Energy analysts say this will challenge the United States, which will likely need to import vastly more minerals like cobalt, lithium and aluminum, at the same time that China has increased its control over the supply of some key resources.People cool off in the beach near the mining pipeline “Puerto Coloso” of the “Escondida” cooper mine in Antofagasta, Chile, Feb. 16, 2017.A VOA examination of U.S. government data shows how China has become the main supplier for some of the most important raw materials that Western countries import, giving Beijing leverage over the materials that go into everything from advanced fighter jets to solar panels.Not only has Beijing bought up some of the world’s biggest mines for these minerals, the country also has invested heavily in the processing facilities that refine the raw materials into industrially-useful products, strengthening Beijing’s position in global supply chains.Beijing has already given the world reason to worry about its reliability as a global supplier. In 2011, it used its position as the top global supplier of rare earth metals to cut exports, driving up prices. China’s critics say Beijing’s dominant position in so-called “critical minerals” gives them similar leverage.Aerial view of evaporation pools of the new state-owned lithium extraction complex, in the southern zone of the Uyuni Salt Flat, Bolivia, on July 10, 2019.35 critical mineralsThe United States has designated A man watches a conveyor belt loaded with chunks of raw cobalt after a first transformation at a plant in Lubumbashi, Congo, on Feb. 16, 2018, before being exported, mainly to China, to be refined.Chinese dominance in U.S. allies’ supply chainsOther Western countries have different lists of minerals considered critical to their economies. Among the lists of Australia, U.K. and Canada, rare earth minerals account for only one of the 24, 41 and 31 critical minerals, respectively. The European Union classifies light and heavy rare earths as two separate critical elements on its 30 Critical Raw Materials (CRM) list.A study published last year by the European Commission’s Joint Research Center, a science and technology service agency, found that the production of a Rafale fighter aircraft requires a total of 16 CRMs, of which only three are rare earth elements. Although each country makes up its own list of “critical minerals” based on its strategic needs, China is a dominant supplier in all of the lists.In the EU’s list, China is the largest source of imports for 10 minerals. Among the 24 critical minerals identified by the Australian government in its Critical Minerals Prospectus 2020 report, China is listed as the largest producer of 11 of them. In the U.K.’s Risk List, China is the leading producer of 23 minerals.Similar findings were reported by Chinese researchers as well. A study published by China Geological Survey stated that “after combing through the list of Critical Minerals in the United States, the European Union, the United Kingdom and other countries, it can be seen that half or more of the country’s main producing countries and main sources of imports are our country.”The 2019 report said that of the 35 key minerals in the U.S., the largest supplier of 13 CMs is China, and China is also the largest producer of 19 CMs.This story originated in VOA’s Mandarin Service.

Workers dig and ferry wheelbarrows laden with sand to open a new shaft at a bustling archaeological site outside of Cairo, while a handful of Egyptian archaeologists supervise from garden chairs. The dig is at the foot of the Step Pyramid of Djoser, arguably the world’s oldest pyramid, and is one of many recent excavations that are yielding troves of ancient artifacts from the country’s largest archaeological site. As some European countries re-open to international tourists, Egypt has already been trying for months to attract them to its archaeological sites and museums. Officials are betting that the new ancient discoveries will set it apart on the mid- and post-pandemic tourism market. They need visitors to come back in force to inject cash into the tourism industry, a pillar of the economy. But like countries elsewhere, Egypt continues to battle the coronavirus, and is struggling to get its people vaccinated. The country has, up until now, received only 5 million vaccines for its population of 100 million people, according to its Health Ministry. In early May, the government announced that 1 million people had been vaccinated, though that number is believed to be higher now. In the meantime, authorities have kept the publicity machine running, focused on the new discoveries. In November, archaeologists announced the discovery of at least 100 ancient coffins dating back to the Pharaonic Late Period and Greco-Ptolemaic era, along with 40 gilded statues found 2,500 years after they were first buried. That came a month after the discovery of 57 other coffins at the same site, the necropolis of Saqqara that includes the step pyramid. “Saqqara is a treasure,” said Tourism and Antiquities Minister Khaled el-Anany while announcing the November discovery, estimating that only 1% of what the site contains has been unearthed so far. “Our problem now is that we don’t know how we can possibly wow the world after this,” he said. If they don’t, it certainly won’t be for lack of trying. FILE – Dr. Zahi Hawass, the renowned Egyptian archeologist credited with discovering the site, leads a media tour of the roughly 3,000-year-old “lost golden city” in Luxor, Egypt, Apr. 10, 2021. (Hamada Elrasam/VOA)In April, Zahi Hawass, Egypt’s best-known archaeologist, announced the discovery of a 3,000-year-old lost city in southern Luxor, complete with mud brick houses, artifacts and tools from pharaonic times. It dates to Amenhotep III of the 18th dynasty, whose reign (1390–1353 B.C.) is considered a golden era for ancient Egypt. That discovery was followed by a made-for-TV parade celebrating the transport of 22 of the country’s prized royal mummies from central Cairo to their new resting place in a massive facility farther south in the capital, the National Museum of Egyptian Civilization. The Red Sea resort of Sharm el-Sheikh is now home to an archaeological museum, as is Cairo’s International Airport, both opened in recent months. And officials have also said they still plan to open the massive new Grand Egyptian Museum next to the Giza Pyramids by January, after years of delays. Entrance fees for archeological sites have been lowered, as has the cost of tourist visas. The government has for years played up its ancient history as a selling point, as part of a yearslong effort to revive the country’s battered tourism industry. It was badly hit during and after the popular uprising that toppled longtime autocrat Hosni Mubarak and the ensuring unrest. The coronavirus dealt it a similar blow, just as it was getting back on its feet. In 2019, foreign tourism’s revenue stood at $13 billion. Egypt received some 13.1 million foreign tourists — reaching pre-2011 levels for the first time. But in 2020, it greeted only 3.5 million foreign tourists, according to the minister el-Anany. At the newly opened National Museum of Egyptian Civilization, Mahmoud el-Rays, a tour guide, was leading a small group of European tourists at the hall housing the royal mummies. “2019 was a fantastic year,” he said. “But corona reversed everything. It is a massive blow.” Tourism traffic strengthened in the first months of 2021, el-Anany, the minister, told The Associated Press in a recent interview, though he did not give specific figures. He was optimistic that more would continue to come year-round. “Egypt is a perfect destination for post-COVID in that our tourism is really an open-air tourism,” he said. But it remains to be seen if the country truly has the virus under control. It has recorded a total of 14,950 deaths from the virus and is still seeing more than a thousand new cases daily. Like other countries, the real numbers are believed to be much higher. In Egypt, though, authorities have arrested doctors and silenced critics who questioned the government’s response, so there are fears that information on the true cost of the virus may have been suppressed from the beginning. Egypt also had a trying experience early on in the pandemic, when it saw a coronavirus outbreak on one of its Nile River cruise boats. It first closed its borders completely until the summer of 2020, but later welcomed tourists back, first to Red-Sea resort towns and now to the heart of the country — Cairo and the Nile River Valley that hosts most of its famous archaeological sites. Visitors still require a negative COVID-19 test result to enter the country. In a further cause for optimism, Russia said in April that it plans to resume direct flights to Egypt’s Red Sea resort towns. Moscow stopped the flights after the local Islamic State affiliate bombed a Russian airliner over the Sinai Peninsula in October 2015, killing all on board. Amanda, a 36-year-old engineer from Austria, returned to Egypt in May. It was her second visit in four years. She visited the Egyptian Museum, the National Museum of Egyptian Civilization and Islamic Cairo, in the capital’s historic center. She had planned to come last year, but the pandemic interfered. “Once they opened, I came,” she said. “It was my dream to see the Pyramids again.” El-Rays, the tour guide, says that while he’s seeing tourists starting to come in larger numbers, he knows a full recovery will not happen overnight. “It will take some time to return to before corona,” he said.

Record numbers of COVID-19 vaccinations have been completed in Australia as a snap seven-day lockdown continues in the nation’s second most-populous state.Seven million people in Victoria are subject to strict stay-at-home orders after a growing cluster of infections was detected in recent days. Australia has managed to mostly contain the coronavirus through lockdowns, the closure of its international borders and strict quarantine measures for returning citizens, but the national vaccination program has been beset by supply issues and hesitancy among many Australians.There are estimated to be 100 active coronavirus cases in Australia, according to the Health Department. About half are in Victoria, which is under a seven-day lockdown. It is the state’s fourth shutdown since the pandemic began.The number of infections in Australia is small compared to other countries, including Japan, Brazil and the United States.However, community transmission of the virus has been rare in recent months and the outbreak in Victoria is significant.There has been complacency in the community and mounting hesitancy about vaccines and possible side effects, which have delayed the national inoculation plan.Health authorities in Victoria, though, have said the lockdown has sent residents flocking to injection centers across the country in record numbers.However, some experts believe that it might be too late to prevent another wave of infections in Australia’s second most populous state.“We have been here before,” said Dr. Michelle Ananda-Rajah, an infectious diseases expert at Melbourne’s Alfred Hospital. “I think, though, that the stakes are higher this time because we have all the factors for what is essentially a perfect storm. We have a largely unvaccinated population; we have winter approaching, and we have an unforgiving variant on the loose at the moment. You know, Victoria is primed at the moment for a third wave, and we need to do everything possible to prevent that from happening.”Melbourne, the Victoria state capital, endured Australia’s longest COVID-19 lockdown last year. Once again, the nation’s second-biggest city finds itself under tight restrictions.Masks are now mandatory. Places of worship and schools are closed. Victorians can only leave home for essential work, shopping, exercise, caregiving or to get a coronavirus vaccine.Businesses are facing heavy losses.A man infected with a highly contagious COVID-19 variant who stayed at a quarantine hotel for returning travelers is thought to be the source of the outbreak.Australia has recorded more than 30,000 coronavirus cases and 910 deaths since the pandemic began, according to government statistics.

It was a boozy joyride captured for TikTok with a soundtrack provided by Justin Bieber and with a Tesla serving as the “Designated Driver” for the night.In the short video, three young men are shown dancing in their seats, beers nearby, as the vehicle moves down the highway near other cars at 105 kph, as shown on the speedometer.Nobody is behind the steering wheel.The video clip, which has been “liked” by nearly 2 million people and shared 105,000 times, is just one of many similar ones on social media reviewed by AFP.Such behavior is illegal and flouts the instructions of the automaker, which says on its website that Tesla’s driver-assistance system is “intended for use with a fully attentive driver, who has their hands on the wheel and is prepared to take over at any moment.”Besides Tesla’s “Autopilot” system, which matches a vehicle’s speed to that of surrounding traffic and assists in steering within a clearly marked lane, Tesla offers what it calls “full self-driving capability.”That program’s capabilities include helping park a car, maneuver a vehicle in and out of a tight parking space and guide a car from a highway on-ramp to an off-ramp.Tesla will alert the driver and ultimately disengage the self-driving system if the driver’s seatbelt is not buckled, or if the hands of the driver are not detected on the steering wheel.Fooling the systemHowever, these protections have proved little match for Tesla motorists determined to misuse their vehicles. The magazine Consumer Reports released a video in which an incredulous tester easily duped a Tesla into driving with no one at the wheel.”Idiots will be idiots, they will find a way to trick the system and that’s not Tesla’s fault, they can put a bunch of other things here people will just defeat it,” a poster calling himself “Dirty Tesla” said in a video on his YouTube page, which has 55,000 subscribers.(“Dirty Tesla” has described himself as the president of a Tesla owner’s club in Michigan but declined to give his name.)But Tesla itself has been less than clear, directing users to follow the rules even as it employs confusing terminology for its driver-assistance programs, and as its leader, Elon Musk, makes sweeping statements about the technology.Musk early this year predicted the company’s vehicles would achieve Level 5 autonomy, or full self-driving, in 2021. Yet in 2015, the billionaire had said that goal would be reached within two years.”Some companies are more careful than others in how they advertise,” said Andrew Kun, an expert in human-computer interactions at the University of New Hampshire.”The problem is overtrust, thinking that the system can do more than it is really able to do,” Kun said. “Of course, that’s the issue with calling it ‘Autopilot’ when it really isn’t.”Deadly accidentsAdding gravity to the matter, a series of fatal crashes have raised suspicions that Tesla’s technology may have been misused.On April 17, two people were killed near Houston after a Tesla smashed into a tree.A preliminary report from the National Transportation Safety Board did not weigh in on whether anyone was behind the wheel. Local police had said nobody was in the driver’s seat.In a fatal crash in May near Los Angeles also under investigation, the driver had posted images on social media of himself driving his Tesla without his hands on the wheel.Despite billions of dollars spent thus far, automakers have yet to produce a vehicle with full autonomy.Tesla’s system has reached Level 2 autonomy under the scale of the Society of Automotive Engineers, still a ways from full autonomy and requiring a person in the driver’s seat who can take control if necessary.California regulators have said they are reviewing whether Tesla’s marketing misleads consumers — specifically, whether it has violated a regulation that “prohibits a company from advertising vehicles for sale or lease as autonomous unless the vehicle meets the statutory and regulatory definition of an autonomous vehicle,” the Department of Motor Vehicles told AFP.

Breathless, fevered and without the extra oxygen that could help keep them alive, the new coronavirus patients at a hospital near Myanmar’s border with India highlight the threat to a health system near collapse since February’s coup.To help her tend the seven COVID-19 patients at Cikha hospital, day and night, chief nurse Lun Za En has a lab technician and a pharmacist’s assistant.Mostly, they offer kind words and acetaminophen.”We don’t have enough oxygen, enough medical equipment, enough electricity, enough doctors or enough ambulances,” Lun Za En, 45, told Reuters from the town of just more than 10,000. “We are operating with three staff instead of 11.”Myanmar’s anti-COVID campaign foundered along with the rest of the health system after the military seized power on Feb. 1 and overthrew elected leader Aung San Suu Kyi, whose government had stepped up testing, quarantine and treatment.Services at public hospitals collapsed after many doctors and nurses joined strikes in a Civil Disobedience Movement at the forefront of the opposition to military rule — and sometimes on the front line of the protests that have been bloodily suppressed.Thirteen medics have been killed, according to World Health Organization data that shows 179 attacks on health workers, facilities and transportation, nearly half of all such attacks recorded worldwide this year, said WHO Myanmar representative Stephan Paul Jost.About 150 health workers have been arrested. Hundreds more doctors and nurses are wanted on incitement charges.Neither a junta spokesman nor the health ministry responded to requests for comment. The junta, which initially made fighting the pandemic one of its priorities, has repeatedly urged medics to return to work. Few have responded.Testing collapsedA worker at one COVID-19 quarantine center in Myanmar’s commercial capital, Yangon, said all the specialist health workers there had joined the Civil Disobedience Movement.”Then again, we don’t receive new patients any more as COVID test centers don’t have staff to test,” said the worker, who declined to give his name for fear of retribution.In the week before the coup, COVID-19 tests nationally averaged more than 17,000 a day. That had fallen below 1,200 a day in the seven days through Wednesday.Myanmar has reported more than 3,200 COVID-19 deaths from more than 140,000 cases, although the slump in testing has raised doubts over data that shows new cases and deaths have largely plateaued since the coup.Now, a health system in crisis is raising concerns about the likely impact of the variants that are sweeping through India, Thailand and other neighbors.Patients with COVID-19 symptoms started showing up at Cikha hospital in mid-May. It is only 6 kilometers from India, and health workers fear the illness could be the highly infectious B.1.617.2 strain, though they lack the means to test for it.”It’s very concerning that COVID-19 testing, treatment and vaccinations are extremely limited in Myanmar as more lives are at risk with new, more dangerous variants spreading,” said Luis Sfeir-Younis, Myanmar COVID-19 operations manager for the International Federation of Red Cross and Red Crescent Societies.Surge of casesTwenty-four cases have been identified in Cikha, said Za En, the nurse. Seven were so serious they needed hospitalization.Stay-at-home orders have now been declared in parts of Chin state, where Cikha is located, and neighboring Sagaing region.The WHO said it was trying to reach authorities and other groups in the area who could provide help, while recognizing the difficulties in a health system that was precipitously reversing years of impressive gains.”It is not clear how this will be resolved, unless there is a resolution at the political level addressing the political conflict,” Jost said.Za En said her hospital was doing the best it could with nebulizers — machines that turn liquid to mist — to relieve breathlessness. Some patients have oxygen concentrators, but they only work for the two hours a day that the town gets electricity.Refusing to abandon the sick, Za En said she decided not to join the strikes.”The junta will not take care of our patients,” she said.Across Myanmar, some striking doctors have set up underground clinics to help patients. When Myanmar Red Cross volunteers established three clinics in Yangon neighborhoods, they quickly had dozens of patients.At best, such options can provide basic care.”Eighty percent of the hospitals are public health hospitals,” said Marjan Besuijen, head of mission for the Medicins Sans Frontieres (MSF) aid group. “As MSF or others we can’t step in, it’s too big.”Although military hospitals have been opened to the public, many people fear them or refuse to go on principle, including for coronavirus vaccinations in a campaign the ousted government had launched days before the coup.”I am very worried that these new infections will spread all over the country,” Za En said. “If the infection spreads to the crowded cities, it could be uncontrollable.”
