Britain’s Conservative government on Wednesday approved the United Kingdom’s first new coal mine in three decades, a decision condemned by environmentalists as a leap backwards in the fight against climate change.

Hours earlier, the government reversed a ban on building new onshore windfarms in Britain. Opponents called that announcement a cynical attempt to offset criticism of the mine decision.

Cabinet Minister Michael Gove decided the mine in the Cumbria area of northwest England would have “an overall neutral effect on climate change and is thus consistent with government policies for meeting the challenge of climate change,” the government said.

It said coal from the mine would be used to make steel — replacing imported coal — rather than for power generation.

The mine will extract coking coal, the type used in steelmaking, from under the Irish Sea and process it on the site of a shuttered chemical plant in Whitehaven, a town 550 kilometers northwest of London.

Supporters say the mine will bring much-needed jobs to an area hard hit by the closure of its mines and factories in recent decades.

Opponents say the mine is a major blow to the U.K.’s status as a world leader in replacing polluting fossil fuels with clean renewable energy. They argue it will undermine global efforts to phase out coal and make it harder for Britain to meet its goals of generating 100% of electricity from clean energy sources by 2035 and reaching net-zero carbon emissions by 2050.

John Gummer, a Conservative politician who heads the Climate Change Committee, a government advisory body, said the decision “sends entirely the wrong signal to other countries about the U.K.’s climate priorities.”

Doug Parr, policy director at Greenpeace U.K., said “the U.K. government risks becoming a superpower in climate hypocrisy rather than climate leadership. How can we possibly expect other countries to rein in fossil fuel extraction when we’re building new coal mines here?”

Britain has taken steps to bolster its domestic energy supply since Russia’s invasion of Ukraine sent oil and gas prices soaring. The U.K. imports little Russian oil or gas, but its lightly regulated energy market leaves customers highly exposed to price fluctuations.

Many homes and businesses have seen bills double or triple in the past year, though a government price cap — due to end in April — has prevented even steeper hikes.

The invasion of Ukraine has made countries across Europe reconsider plans to cut their use of fossil fuels. Britain has also approved more North Sea oil and gas drilling, while the Czech Republic reversed a plan to stop coal mining in a key region.

France recently restarted a shuttered coal plant, abandoning an earlier vow by President Emmanuel Macron to close all coal-burning plants in the country by the end of this year.

The mine decision came a day after Prime Minister Rishi Sunak lifted a ban on building new windfarms on British soil.

Wind produced more than a quarter of the U.K.’s electricity in 2021. But since 2015, the Conservative government has opposed new wind turbines on land because of local opposition. A majority of Britain’s wind farms are at sea.

While running for the Conservative Party’s leadership in the summer, Sunak pledged to keep the ban. But amid growing calls for change from Conservative lawmakers, the government said Tuesday it could allow wind farms in areas where communities support them, pending a “technical consultation.”

Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. Today, it’s a barren Arctic desert, but back then it was a lush landscape of trees and vegetation with an array of animals, even the now extinct mastodon.

“The study opens the door into a past that has basically been lost,” said lead author Kurt Kjaer, a geologist and glacier expert at the University of Copenhagen.

With animal fossils hard to come by, the researchers extracted environmental DNA, also known as eDNA, from soil samples. This is the genetic material that organisms shed into their surroundings — for example, through hair, waste, spit or decomposing carcasses.

Studying really old DNA can be a challenge because the genetic material breaks down over time, leaving scientists with only tiny fragments.

But with the latest technology, researchers were able to get genetic information out of the small, damaged bits of DNA, said senior author Eske Willerslev, a geneticist at the University of Cambridge. In their study, published Wednesday in the journal Nature, they compared the DNA to that of different species, looking for matches.

The samples came from a sediment deposit called the Kap Kobenhavn formation in Peary Land. Today, the area is a polar desert, Kjaer said.

But millions of years ago, this region was undergoing a period of intense climate change that sent temperatures up, Willerslev said. Sediment likely built up for tens of thousands of years at the site before the climate cooled and cemented the finds into permafrost.

The cold environment would help preserve the delicate bits of DNA — until scientists came along and drilled the samples out, beginning in 2006.

During the region’s warm period, when average temperatures were 20 to 34 degrees Fahrenheit (11 to 19 degrees Celsius) higher than today, the area was filled with an unusual array of plant and animal life, the researchers reported. The DNA fragments suggest a mix of Arctic plants, like birch trees and willow shrubs, with ones that usually prefer warmer climates, like firs and cedars.

The DNA also showed traces of animals including geese, hares, reindeer and lemmings. Previously, a dung beetle and some hare remains had been the only signs of animal life at the site, Willerslev said.

One big surprise was finding DNA from the mastodon, an extinct species that looks like a mix between an elephant and a mammoth, Kjaer said.

Many mastodon fossils have previously been found in what were temperate forests in North America. That’s an ocean away from Greenland, and much farther south, Willerslev said.

“I wouldn’t have, in a million years, expected to find mastodons in northern Greenland,” said Love Dalen, a researcher in evolutionary genomics at Stockholm University who was not involved in the study.

Because the sediment built up in the mouth of a fjord, researchers were also able to get clues about marine life from this time period. The DNA suggests horseshoe crabs and green algae lived in the area — meaning the nearby waters were likely much warmer back then, Kjaer said.

By pulling dozens of species out of just a few sediment samples, the study highlights some of eDNA’s advantages, said Benjamin Vernot, who researches ancient DNA at Germany’s Max Planck Institute for Evolutionary Anthropology and was not involved in the study.

“You really get a broader picture of the ecosystem at a particular time,” Vernot said. “You don’t have to go and find this piece of wood to study this plant, and this bone to study this mammoth.”

Based on the data available, it’s hard to say for sure whether these species truly lived side by side, or if the DNA was mixed together from different parts of the landscape, said Laura Epp, an eDNA expert at Germany’s University of Konstanz who was not involved in the study.

But Epp said this kind of DNA research is valuable to show “hidden diversity” in ancient landscapes.

Willerslev believes that because these plants and animals survived during a time of dramatic climate change, their DNA could offer a “genetic roadmap” to help us adapt to current warming.

Stockholm University’s Dalen expects ancient DNA research to keep pushing deeper into the past. He worked on the study that previously held the “oldest DNA” record, from a mammoth tooth around a million years old.

“I wouldn’t be surprised if you can go at least one or perhaps a few million years further back, assuming you can find the right samples,” Dalen said.

A law allowing limited euthanasia in Canada is set to expand to make the procedure available to people with mental illness. As Craig McCulloch reports, this is causing a variety of reactions.

Canada’s law permitting euthanasia, or Medical Assistance in Dying, became personal for Vancouver-area resident Marcia McNaughton in November. Suffering from metastasized stomach cancer, her 80-year-old aunt Ella Tikenheinrich chose to end her life with medical assistance.

McNaughton was not aware of her aunt’s choice until almost the end, and the extended family supported it.

“As a family, all we did was support her and love her decision,” McNaughton said. “And I have to say one thing — to be in control of your own time, it is an amazing thing.”

On March 17, the law permitting what is termed Medical Assistance in Dying — commonly called MAiD — will expand to include those suffering from mental illness. Currently, only individuals whose death is deemed to be reasonably foreseeable or who suffer from a debilitating illness, like McNaughton’s aunt, qualify to get medical assistance to end their life.

Ottawa-based Canadian Physicians for Life has always been strongly opposed to any form of legalized euthanasia.

Executive Director Nicole Scheidl said it is an abdication of responsibility of the government and doctors to offer death as a solution instead of treatment. She feels the coming changes allow for a doctor to decide who gets medical assistance to die and who gets suicide prevention.

“That goes to the very heart of what the physician thinks — the quality of life of the person in front of them,” Scheidl said. “And clearly, that’s not a decision that should ever fall to a doctor. As well, people who are suicidal don’t clearly see that they need suicide prevention. They all want suicide assistance.”

Victoria-based lawyer Chris Considine has been at the forefront of strongly advocating for euthanasia going back three decades. In the early 1990s, he represented Sue Rodriguez, who was dying from amyotrophic lateral sclerosis, or ALS, taking her fight for a doctor-assisted death all the way to the Supreme Court of Canada.

Although they lost that case on a 5 to 4 vote, the decision was overturned in 2016. Rodriguez got a doctor-assisted death from an unnamed person in February 1994.

Considine still supports medically assisted suicide but says unlike a terminal illness such as ALS or cancer, issues involving mental health are not as clear cut.

He said there has been a dramatic increase in mental health illnesses, but not treatment.

“In addition, there are underlying causes for mental health which are not strictly organic,” Considine said. “There may be depression caused by poor housing, poor job prospects and other issues, which will drive people into a deep depression. Those issues could be solved, and therefore, there may not really be a need for MAiD.”

Considine said if the March date for expanding the euthanasia law is not pushed back, he hopes strict guidelines are put in place so it does not become a substitute for housing, health care and other forms of social assistance.

Negotiators are meeting in Geneva this week to thrash out a pandemic treaty aimed at ensuring the flaws that turned COVID-19 into a global crisis could never happen again. 

As the third anniversary of the emergence of the virus rolls around, negotiators are raking over an early concept draft of what might eventually make it into an international agreement about how to handle future pandemics. 

“The lessons of the pandemic must not go unlearned,” WHO chief Tedros Adhanom Ghebreyesus told the negotiating panel at the start of three days of talks, which conclude Wednesday. 

An intergovernmental negotiating body is paving the way toward a global agreement that would regulate how nations prepare for and respond to future pandemic threats. 

They are gathered for their third meeting, refining and going over their ideas so far. 

A progress report will be put before WHO member states next year, with the final outcome to be presented for their consideration in May of 2024. 

The dense, 32-page early draft “is a true reflection of the aspirations for a different paradigm for strengthening pandemic prevention, preparedness, response and recovery,” said Tedros. 

The so-called conceptual zero draft contains various notions, some of which will have to be developed and others thrown out as negotiators pare down the text ahead of the next meeting in February. 

The trick will ultimately be finding the balance between something bold and with teeth, and something all countries can agree to. 

‘Don’t blow this opportunity’

“There’s a lot of material currently that probably doesn’t belong in there,” said Pamela Hamamoto, the lead U.S. negotiator. 

“There’s a lot that needs to change before we’re going to sign onto it. That is the same for a lot of member states — probably most,” she told reporters. 

Hamamoto said Washington wanted to see transparency fixed into the accord, along with better surveillance and rapid response, plus swift and comprehensive data sharing. 

The United States also wants to see more equitable access to medical countermeasures, possibly through regional manufacturing. 

“A pretty broadly-held view is that we need to make sure that the process is set up right so … we basically don’t blow this opportunity to put together an accord that is going to be meaningful and implementable,” Hamamoto said. 

The Panel for a Global Public Health Convention, an independent coalition of statespeople and health leaders, said the conceptual draft did not go far enough, despite its bright spots. 

The panel said more should be done to establish accountability and clear timelines for alert and response to avoid damaging consequences when an outbreak emerges. 

Negotiations at ‘crossroads’

The medical charity Doctors Without Borders said the negotiations must not overlook the role of clinical trials in any pandemic response. 

Mohga Kamal-Yanni, of the NGO coalition People’s Vaccine Alliance, said the draft showed negotiations were “at a crossroads.” 

“A treaty could break with the greed and inequality that has plagued the global response to COVID-19, HIV/AIDS and other pandemics. Or it could tie future generations to the same disastrous outcomes,” she said. 

“Governments must resist any attempts to turn a pandemic treaty into another obscene profit opportunity for pharmaceutical companies.” 

Three years in, the pandemic still has power to disrupt lives and societies — as seen in the recent unrest in China over lockdowns. 

Countries have reported 6.6 million deaths to the WHO, while around 640 million confirmed cases have been registered.  

But the U.N. health agency says this will be a massive undercount. 

Global Fund executive director Peter Sands told reporters last month that “having a nice treaty … will have only a partial impact on how effectively we respond.” 

He said the world was undoubtedly already better prepared for the next pandemic but warned: “That doesn’t mean we are well prepared. It just means we’re not as badly prepared as we were before.”

Price increases among seven out of 10 drugs in 2021 are behind an $805 million increase in U.S. spending from the year before and were not supported by clinical evidence, an influential U.S. pricing research firm said on Tuesday. 

The Institute for Clinical and Economic Review (ICER) said the spending increase in 2021 was less than the $1.67 billion rise in the previous year. This is the third year the group has looked at the top 250 drugs by spending and assessed if those driving U.S. spending increases were justified.

“Last year, a huge part of the (increase in) spending was all one drug … this year, we saw the increase was more spread out across different drugs,” ICER’s Chief Medical Officer David Rind told Reuters. 

In 2020, Abbvie’s rheumatoid arthritis therapy Humira led to an almost $1.4 billion increase in U.S. drug spending, accounting for more than 80% of the total increase. 

Rind said Humira dropped off the list of the 10 costliest prescription drugs because its net price hike was lower in 2021. Since there was no single drug that drove the increase in spending this year, the rise is also relatively smaller compared with 2020, he added. 

Bausch Health’s Xifaxan, an antibiotic drug for traveler’s diarrhea, led to an increase of nearly $175 million in spending, among the highest this year. 

Johnson & Johnson’s schizophrenia therapy Invega Sustenna and Amgen’s osteoporosis drug Prolia followed closely with spending increases of $170 million and $124 million, respectively. 

The three drugmakers did not immediately respond to Reuters’ requests for comment. 

President Joe Biden’s signature Inflation Reduction Act will allow the government to choose 10 drugs to negotiate the prices of from among the 50 costliest drugs for Medicare, the government health care program for people age 65 and older or disabled, starting in 2026.

NASA’s Orion spaceship made a close pass by the moon and used a gravity assist to whip itself back toward Earth on Monday, marking the start of the return journey for the Artemis-1 mission.

At its nearest point, the uncrewed capsule flew less than 130 kilometers from the moon’s surface, testing maneuvers that will be used during later Artemis missions that return humans to the rocky celestial body.

Communication with the capsule was interrupted for 30 minutes when it was behind the far side of the moon, an area more cratered than the near side and first seen by humans during the Apollo era, although they didn’t land there.

The European Service Module, which powers the capsule, fired its main engine for more than three minutes to put the gumdrop-shaped Orion on course for home.

“We couldn’t be more pleased about how the spacecraft is performing,” Debbie Korth, Orion Program deputy manager, said later.

As spectacular footage flashed on their screens once communication was restored, she told a news conference, “everybody in the room, we just kind of had to stop and pause, and just really look — ‘Wow, we’re saying goodbye to the moon.'”

Monday’s maneuver was the last major one of the mission, which began when NASA’s mega moon rocket SLS blasted off from Florida on November 16. From start to finish, the journey should last 25½ days.

Orion will now make only slight course corrections until it splashes down in the Pacific Ocean off San Diego on Sunday at 9:40 a.m. local time (1740 GMT). It will then be recovered and hoisted aboard a U.S. Navy ship.

Earlier in the mission, Orion spent about six days in “distant retrograde orbit” around the moon, meaning at high altitude and traveling opposite the direction the moon revolves around Earth.

A week ago, Orion broke the distance record for a habitable capsule, venturing 450,000 kilometers from Earth.

Once it returns to Earth, Orion will have traveled more than 1.4 million miles, said Mike Sarafin, the Artemis mission manager.

Re-entry into Earth’s atmosphere will present a harsh test for the spacecraft’s heat shield, which will need to withstand temperatures of around 2,800 degrees Celsius – or about half the temperature of the surface of the sun.

Under the Artemis program — named for the sister of Apollo in Greek mythology — the United States is seeking to build a lasting presence on the moon in preparation for an onward voyage to Mars.

Artemis 2 will involve a crewed journey to the moon, once again without landing.

The first woman and next man are to land on the lunar south pole during Artemis 3, which is set for no sooner than 2025, though likely significantly later given timeline delays.

Beijing is taking its first steps toward recovering from years of setbacks to its scientific, land-based projects in the Arctic, sending personnel to two outposts that have been vital to its policy of establishing China as a “near-Arctic” state.

China’s Arctic policy document, published in 2018, said scientific research to “explore and understand” the Arctic is the “priority and focus” of Chinese participation in Arctic affairs.

Over a 14-year period since 2004, China launched scientific projects in Arctic regions of four Western European nations — Norway, Iceland, Sweden and Finland — and sought to do the same in a fifth, Denmark’s autonomous island of Greenland.

The Biden administration, which published its own “National Strategy for the Arctic Region” in October, said those scientific projects have helped China to increase its influence in the Arctic and “exacerbated” strategic competition in a region where the U.S. has long been a major power.

The U.S. strategy document said China has “used these scientific engagements to conduct dual-use research with intelligence or military applications in the Arctic,” requiring the U.S. to respond by positioning itself to “effectively compete and manage tensions” in the region.

China’s state-run Global Times newspaper quickly responded to the U.S. strategy with an article citing Chinese analysts as saying Washington has been “politicizing” China’s activities in the Arctic. It said the analysts see the U.S. “using ‘increased competition’ as an excuse in trying to control the region after seeing its increasingly prominent economic and military value.”

As it snipes publicly at the U.S., Beijing has been less vocal about setbacks to its land-based Arctic scientific projects in recent years and its nascent moves to revive some of them.

Arctic researchers have told VOA that China recently has sent and announced plans to imminently send several people to its two most important scientific outposts in Norway and Iceland after lengthy absences of Chinese scientists from both sites. But there have been no signs of China trying to renew two other scientific projects in Sweden and Finland where national organizations told VOA that Chinese activity is set to end or has ended.

The Polar Research Institute of China (PRIC) recently registered three projects in the scientific community of Ny-Alesund in Norway’s Svalbard archipelago, where it has rented and operated a Norwegian-owned building since 2004 called Yellow River Station, its first Arctic ground facility. PRIC registered the projects on Norway’s Research in Svalbard Portal.

Scientist Geir Gotaas, leader of the Ny-Alesund Program at the Norwegian Polar Institute, said Chinese personnel have been mostly absent from Yellow River Station since the start of the pandemic because of travel restrictions. He said the last Chinese researcher departed in March after a solo three-month stay at the building, which has a capacity of 37 staff and accommodated the largest foreign contingent of scientists in Ny-Alesund before the pandemic.

Gotaas said four Chinese scientists will arrive in the Norwegian mainland this week before flying to Svalbard, with three staying for a few weeks in Longyearbyen and Ny-Alesund and the fourth remaining at Yellow River Station until March to maintain instruments over winter.

“The Chinese researchers are making a first step towards a return to regular operations in Ny-Alesund,” Gotaas said.

In northern Iceland’s Karholl, six Chinese personnel, including four scientists, arrived at the China Iceland Arctic Research Observatory (CIAO) late last month after a three-year Chinese absence from the complex, according to its spokesperson, Halldor Johannsson, director of the Arctic Portal.org news organization.

Johannsson said pandemic travel restrictions had kept the Chinese personnel away from CIAO, which opened in 2018 and is jointly operated by China’s PRIC and the Icelandic Center for Research (Rannis). The recently arrived Chinese contingent has met with local scientists and community leaders and was to depart in early December, he added.

CIAO consists of a new research building and several farmhouses for accommodation and other uses. China fully funded the building’s construction but does not own anything at the site and rents the property from Icelandic nonprofit group Aurora Observatory, Johannsson said.

In northern Sweden’s Esrange Space Center, contracts enabling three Chinese scientific agencies to use four satellite dish antennas built from 2008 to 2016 will not be renewed, according to Philip Ohlsson, Swedish Space Corporation (SSC) head of communications.

SSC controls all data received from and sent to satellites by the antennas, three of which are SSC-owned while the fourth is Chinese-owned, Ohlsson wrote in a series of emails. He said Chinese personnel have visited Esrange from time to time but never have been stationed there.

“In 2018, SSC took the decision not to enter into any new contracts with Chinese customers, given the limited size of our company in relation to the complexity of the Chinese market,” Ohlsson said.

He declined to reveal when the existing contracts will end, “out of respect for our customers and the confidentiality of these contracts.”

In northern Finland’s Sodankyla Space Campus, a joint research project launched by the Finnish Meteorological Institute (FMI) and Chinese Academy of Sciences (CAS) in 2018, ended last year when a three-year agreement expired, said Jouni Pulliainen, FMI Space and Earth Observation Center director.

CAS announced in 2018 that a joint research center for Arctic space observation and data sharing would be “constructed” in Sodankyla. But Pulliainen wrote in an email that there was no new construction at the space campus and the project mainly involved temporary visits by five Chinese researchers to Sodankyla’s existing facilities before the start of the pandemic.

Pulliainen said the outcome of the project was “not as impressive” as the Chinese side had originally expressed through state media.

“Due to changes in the world’s political situation, we were not any more so interested in deepening the cooperation activities, and we were not contacted from CAS about the renewal of the agreement,” he added.

China also never realized its 2017 proposal to build a satellite dish antenna ground station for remote sensing in the Greenlandic capital of Nuuk.

Beijing Normal University Dean Cheng Xiao held a “launch” ceremony in the Greenlandic town of Kangerlussuaq for the proposed Nuuk ground station on May 30, 2017. A group of more than 100 Chinese visitors attended the event along with two representatives of Greenlandic NGOs, but the project never won approval from the Greenlandic and Danish governments and did not proceed.

China’s foreign ministry did not respond to a VOA email asking why Beijing did not send personnel to the Norwegian and Icelandic project sites for lengthy periods, why it did not reach agreements to extend the Swedish and Finnish projects and why the Greenlandic project never got off the ground.

Marc Lanteigne, a social studies professor at the Arctic University of Norway, said China ran into local opposition for some of its projects.

“I’m thinking primarily of China’s plan to set up a research base in Greenland that was announced to great fanfare and then ran smack into Danish opposition,” Lanteigne said. Denmark, a NATO member, has been “very touchy about anything that might look like a Chinese strategic beachhead” in Greenland, he added.

Lanteigne said China’s diplomatic disputes with some European Arctic nations have undermined the progress of its other scientific projects.

“China’s relations with Sweden really have begun to sour over the past few years due to human rights issues, and that has affected the ability of Chinese researchers to set up any kind of a base in Sweden itself,” he said.

Nengye Liu, a law professor at Singapore Management University, said he expects Beijing to focus on developing its more established Arctic projects in Norway and Iceland rather than on smaller projects that ran into obstacles in other nations.

As Arctic ice melts because of climate change, China sees new opportunities for shipping, fisheries and oil and gas development in the region, Liu said.

“So all these scientific activities are meant to ensure that a major economic power like China won’t be left behind. That is why China describes itself as a ‘near-Arctic’ state,” Liu said.

VOA emailed the White House to request a National Security Council comment on what the U.S. is doing to manage tensions arising from China’s scientific projects in the Arctic but did not receive a response.

In an October forum at Washington’s Wilson Center, Devon Brennan, NSC director for maritime and Arctic security, said the U.S. is concerned that China’s exploitation of Arctic resources, such as fisheries and hydrocarbons, may diverge from what he called the rules-based international order.

But Brennan also said the U.S. recognizes that China has a “vested interest” in the region.

“While first and foremost, we will want to work with our like-minded partners and allies in the Arctic, there is room to cooperate with other non-Arctic nations for the betterment of the region,” he said.

“Today, there are more children in need of humanitarian assistance than at any other time in recent history,” according to UNICEF Executive Director Catherine Russell. 

Monday, UNICEF, the United Nations children’s agency, launched an emergency appeal for $10.3 billion, designed to help 173 million people, including 110 million children, that the agency says have been impacted by “humanitarian crises, the enduring effects of the COVID-19 pandemic worldwide and the growing threat of climate-impacted severe weather events.” 

The agency says climate change “is also worsening the scale and intensity of emergencies,” with the last 10 years being the hottest on record. In the last 30 years, the number of climate-related disasters has tripled, UNICEF says.  

“Today, over 400 million children live in areas of high or extremely high-water vulnerability,” according to UNICEF.  

Russell said, “The devastating impacts of climate change are an ever-present threat to children” and that is why UNICEF is “prioritizing climate adaptation and resilience building as part of our humanitarian response.”

In a remote corner of the Western Australian outback, work has begun on the world’s largest radio telescope. Astronomers say the Square Kilometre Array will be capable of searching the stars for signals of intelligent life and listening back to the start of the universe.

It is an international scientific collaboration. 130,000 antennas and 200 satellite dishes will make up the Square Kilometre Array project, or SKA. It will comprise two giant and super sensitive telescopes at observatories in Australia and South Africa.

By listening and looking deep into space, scientists hope the project can help answer some fundamental questions: Are we alone in the universe? How did the first stars come to shine? and What exactly is “dark energy” — the mysterious phenomena that appears to be pulling the cosmos apart?

Experts have said the SKA needs to be set up far away from the disturbances of radio frequencies on earth like those from computers, cars and planes.

They have said it will be eight times more sensitive than existing telescopes and will map the sky 135 times faster.

Danny Price, a senior research fellow at the Curtin Institute of Radio Astronomy at Curtin University, told the Australian Broadcasting Corp. Monday that the SKA has unprecedented astronomical power.

“It is going to be one of the most sensitive instruments that humanity has ever built,” Price said. “To put it into perspective the SKA could detect a mobile phone in the pocket of an astronaut on Mars.”

Australia, South Africa, Canada and Britain are among more than a dozen countries providing funding to the project.

A land agreement between traditional Indigenous owners, the Commonwealth Scientific and Industrial Research Organization — the CSIRO, Australia’s national science agency and the Western Australian and federal governments has allowed construction of the international Square Kilometre Array telescope to officially start Monday.

The giant radio telescope is expected to be operational by the end of the decade.

China on Sunday reported two additional deaths from COVID-19 as some cities move cautiously to ease anti-pandemic restrictions following increasingly vocal public frustrations.

The National Health Commission said one death was reported each in the provinces of Shandong and Sichuan. No information was given about the ages of the victims or whether they had been fully vaccinated.

China, where the virus first was detected in late 2019 in the central city of Wuhan, is the last major country trying to stop transmission completely through quarantines, lockdowns and mass testing. Concerns over vaccination rates are believed to figure prominently in the ruling Communist Party’s determination to stick to its hard-line strategy.

While nine in 10 Chinese have been vaccinated, only 66% of people over 80 have gotten one shot while 40% have received a booster, according to the commission. It said 86% of people over 60 are vaccinated.

Given those figures and the fact that relatively few Chinese have been built up antibodies by being exposed to the virus, some fear millions could die if restrictions were lifted entirely.

Yet, an outpouring of public anger appears to have prompted authorities to lift some of the more onerous restrictions, even as they say the “zero-COVID” strategy — which aims to isolate every infected person — is still in place.

The demonstrations, the largest and most widely spread in decades, erupted Nov. 25 after a fire in an apartment building in the northwestern city of Urumqi killed at least 10 people. That set off angry questions online about whether firefighters or victims trying to escape were blocked by locked doors or other anti-virus controls. Authorities denied that, but the deaths became a focus of public frustration.

The country saw several days of protests across cities including Shanghai and Beijing, with protesters demanding an easing of COVID-19 curbs. Some demanded Chinese President Xi Jinping step down, an extraordinary show of public dissent in a society over which the ruling Communist Party exercises near total control.

Beijing and some other Chinese cities announced that riders can board buses and subways without a virus test for the first time in months. The requirement has led to complaints from some Beijing residents that even though the city has shut many testing stations, most public venues still require COVID-19 tests.

On Sunday, China announced another 35,775 cases from the past 24 hours, 31,607 of which were asymptomatic, bringing its total to 336,165 with 5,235 deaths.

While many have questioned the accuracy of the Chinese figures, they remain relatively low compared to the U.S. and other nations which are now relaxing controls and trying to live with the virus that has killed at least 6.6 million people worldwide and sickened almost 650 million.

China still imposes mandatory quarantine for incoming travelers even as its infection numbers are low compared to its 1.4 billion population.

It’s now a lot easier — and cheaper — for many hard-of-hearing Americans to get help.

Hearing aids can now be sold without a prescription from a specialist. Over-the-counter, or OTC, hearing aids started hitting the market in October at prices that can be thousands of dollars lower than prescription hearing aids.

About 30 million people in the United States deal with hearing loss, according to the Food and Drug Administration. But only about 20% of those who could use a hearing aid seek help.

Here’s a closer look:

Who might be helped

The FDA approved OTC hearing aids for adults with mild-to-moderate hearing loss. That can include people who have trouble hearing phone calls or who turn up the TV volume loud enough that others complain.

It also can include people who have trouble understanding group conversations in noisy places.

OTC hearing aids aren’t intended for people with deeper hearing loss, which may include those who have trouble hearing louder noises, like power tools and cars. They also aren’t for people who lost their hearing suddenly or in just one ear, according to Sterling Sheffield, an audiologist who teaches at the University of Florida. Those people need to see a doctor.

Hearing test

Before over-the-counter, you usually needed to get your hearing tested and buy hearing aids from a specialist. That’s no longer the case.

But it can be hard for people to gauge their own hearing. You can still opt to see a specialist just for that test, which is often covered by insurance, and then buy the aids on your own. Check your coverage before making an appointment.

There also are a number of apps and questionnaires available to determine whether you need help. Some over-the-counter sellers also provide a hearing assessment or online test.

Who’s selling

Several major retailers now offer OTC hearing aids online and on store shelves.

Walgreens drugstores, for example, are selling Lexie Lumen hearing aids nationwide for $799. Walmart offers OTC hearing aids ranging from about $200 to $1,000 per pair. Its health centers will provide hearing tests.

The consumer electronics chain Best Buy has OTC hearing aids available online and in nearly 300 stores. The company also offers an online hearing assessment, and store employees are trained on the stages of hearing loss and how to fit the devices.

Overall, there are more than a dozen manufacturers making different models of OTC hearing aids.

New devices will make up most of the OTC market as it develops, Sheffield said. Some may be hearing aids that previously required a prescription, ones that are only suitable for people with mild to moderate hearing loss.

Shoppers should expect a lot of devices to enter and leave the market, said Catherine Palmer, a hearing expert at the University of Pittsburgh.

“It will be quite a while before this settles down,” she said.

What to watch for

Look for an OTC label on the box. Hearing aids approved by the FDA for sale without a prescription are required to be labeled OTC.

That will help you distinguish OTC hearing aids from cheaper devices sometimes labeled sound or hearing amplifiers — called a personal sound amplification product or PSAP. While often marketed to seniors, they are designed to make sounds louder for people with normal hearing in certain environments, like hunting. And amplifiers don’t undergo FDA review.

“People really need to read the descriptions,” said Barbara Kelley, executive director of the Hearing Loss Association of America.

And check the return policy. That’s important because people generally need a few weeks to get used to them, and make sure they work in the situations where they need them most. That may include on the phone or in noisy offices or restaurants.

Does the company selling OTC devices offer instructions or an app to assist with setup, fit and sound adjustments? A specialist could help too, but expect to pay for that office visit, which is rarely covered by insurance.

Sheffield said hearing aids are not complicated, but wearing them also is not as simple as putting on a pair of reading glasses.

“If you’ve never tried or worn hearing aids, then you might need a little bit of help,” he said.

The cost

Most OTC hearing aids will cost between $500 and $1,500 for a pair, Sheffield said. He noted that some may run up to $3,000.

And it’s not a one-time expense. They may have to be replaced every five years or so.

Hearing specialists say OTC prices could fall further as the market matures. But they already are generally cheaper than their prescription counterparts, which can run more than $5,000.

The bad news is insurance coverage of hearing aids is spotty. Some Medicare Advantage plans offer coverage of devices that need a prescription, but regular Medicare does not. There are discounts out there, including some offered by Medicare Advantage insurer UnitedHealthcare in partnership with nonprofit organization AARP.

Shoppers also can pay for the devices with money set aside in health savings accounts or flexible spending accounts.

Don’t try to save money by buying just one hearing aid. People need to have the same level of hearing in both ears so they can figure out where a sound is coming from, according to the American Academy of Audiology.
