Brazil’s Lula pledges to finish paving road experts say could worsen Amazon deforestation

brasilia — In a visit to see the damage caused by drought and fire in the Amazon, President Luiz Inacio Lula da Silva pledged to pave a road that environmentalists and some in his own government say threatens to vastly increase destruction of the world’s largest tropical forest — and contribute to climate change. 

The BR-319 roadway is a mostly dirt road through the rainforest that connects the states of Amazonas and Roraima to the rest of the country. It ends in Manaus, the Amazon’s largest city with over 2 million people, and runs parallel to the Madeira River, a major tributary of the Amazon River. The Madeira is at its lowest recorded level, disrupting cargo navigation, with most of its riverbed now endless sand dunes under a sky thick with smoke. 

“We are aware that, while the river was navigable and full, the highway didn’t have the importance it has now, while the Madeira River was alive. We can’t leave two capitals isolated. But we will do it with the utmost responsibility,” Lula said Tuesday during a visit to an Indigenous community in Manaquiri, in Amazonas state. He didn’t specify what steps the government would take to try to prevent deforestation from increasing after paving. 

Hours later, he oversaw the signing of a contract to pave 52 kilometers (32 miles) of the road, and promised to begin work before his term ends in 2026 on the most controversial section of the road — a 400-kilometer (249-mile) stretch through old-growth forest. 

A permit for the longer stretch was issued under Lula’s far-right predecessor, Jair Bolsonaro, who favored development in the Amazon and weakened environmental protections. In July, a federal court suspended the permit in a lawsuit brought by the Climate Observatory, a network of 119 environmental, civil society and academic groups. 

Lula’s government had appealed the suspension, but it wasn’t until his visit on Tuesday that Lula made clear his plan to move ahead with paving. The Climate Observatory lamented the move. 

“Without the forest, there is no water, it’s interconnected,” said Suely Araujo, a public policy coordinator with the group. “The paving of the middle section of BR-319, without ensuring environmental governance and the presence of the government in the region, will lead to historic deforestation, as pointed out by many specialists and by Brazil’s federal environmental agency in the licensing process.” 

Lula has sought to portray himself as an environmental protector, and deforestation has slowed significantly since he took over for Bolsonaro. But he has also struck out at times against pressure from richer nations on preserving the Amazon, an invaluable resource for the planet in storing the carbon driving atmospheric warming, and did so again on Tuesday. 

“The world that buys our food is demanding that we preserve the Amazon,” he said. “And why? Because they want us to take care of the air they breathe. They didn’t preserve their own lands in the last century during the Industrial Revolution.” 

Brazil is enduring its worst drought ever recorded, with 59% of the country under stress — an area about half the size of the U.S. In the Amazon, rivers’ low levels have stranded hundreds of riverine communities, with shortage of potable water and food. Lula announced a wide distribution of water filters and other measures during his visit to the region. 

Meanwhile, most of Brazil has been under a thick layer of smoke from wildfires in the Amazon, affecting millions of people in faraway cities such as Sao Paulo, Brasilia and Curitiba and reaching as far south as Argentina and Paraguay. At Lula’s event, Environment Minister Marina Silva blamed the extreme drought brought by climate change for the widespread fires in a rainforest usually resistant to fire, calling it “a phenomenon we don’t even know how to handle.” 

Silva has been more cautious than Lula about paving the roadway. At a congressional hearing earlier, she called the Bolsonaro era’s permit a “sham” and praised the judicial ruling that suspended it. 

Brazil is the world’s fifth-largest emitter of greenhouse gases, contributing nearly 3% of global emissions, according to Climate Watch, an online platform managed by the World Resources Institute. Almost half these emissions stem from destruction of trees in the Amazon rainforest. 

Tech billionaire pulls off first private spacewalk high above Earth

CAPE CANAVERAL, Florida — A tech billionaire performed the first private spacewalk hundreds of kilometers above Earth on Thursday, a high-risk endeavor reserved for professional astronauts — until now.

Tech entrepreneur Jared Isaacman teamed up with SpaceX to test the company’s brand new spacesuits on his chartered flight. The daring spacewalk also saw SpaceX engineer Sarah Gillis going out once Isaacman was safely back inside.

This spacewalk was simple and quick — less than two hours — compared with the drawn-out affairs conducted by NASA. Astronauts at the International Space Station often need to move across the sprawling complex for repairs, always traveling in pairs and lugging gear. Station spacewalks can last seven to eight hours.

Isaacman emerged first from the hatch, joining a small elite group of spacewalkers who until now had included only professional astronauts from a dozen countries.

“Back at home, we all have a lot of work to do. But from here, it sure looks like a perfect world,” Isaacman said as the capsule soared above the South Pacific. Cameras on board caught his silhouette, waist high at the hatch, with the blue Earth beneath.

The commercial spacewalk was the main focus of the five-day flight financed by Isaacman and Elon Musk’s company, and the culmination of years of development geared toward settling Mars and other planets.

All four on board donned the new spacewalking suits to protect themselves from the harsh vacuum. They launched on Tuesday from Florida, rocketing farther from Earth than anyone since NASA’s moonwalkers. The orbit was reduced by half — 740 kilometers — for the spacewalk.

This first spacewalking test involved more stretching than walking. Isaacman kept a hand or foot attached to it the whole time as he flexed his arms and legs to see how the new spacesuit held up. The hatch sported a walker-like structure for extra support.

After about 15 minutes outside, Isaacman was replaced by SpaceX engineer Sarah Gillis to go through the same motions. Gillis bobbed up and down in weightlessness, no higher than her knees out of the capsule, as she twisted her arms and sent reports back to Mission Control.

Each had 3.6-meter tethers but did not unfurl them or dangle at the end unlike what happens at the space station, where astronauts routinely float out at a much lower orbit.

More and more wealthy passengers are plunking down huge sums for rides aboard private rockets to experience a few minutes of weightlessness. Other have spent tens of millions to stay in space for days or even weeks. Space experts and risk analysts say it’s inevitable that some will seek the thrill of spacewalking, deemed one of the most dangerous parts of spaceflight after launch and reentry but also the most soul-stirring.

This operation was planned down to the minute with little room for error. Trying out new spacesuits from a spacecraft new to spacewalking added to the risk. So did the fact that the entire capsule was exposed to the vacuum of space.

There were a few glitches. Isaacman had to manually pull the hatch open instead of pushing a button on board. Before heading out, Gillis reported seeing bulges in the hatch seal.

Scott “Kidd” Poteet, a former Air Force Thunderbird pilot, and SpaceX engineer Anna Menon stayed strapped to their seats to monitor from inside. All four underwent intensive training before the trip.

Isaacman, 41, CEO and founder of the Shift4 credit card-processing company, has declined to disclose how much he invested in the flight. It was the first of three flights in a program he’s dubbed Polaris; this one was called Polaris Dawn. For SpaceX’s inaugural private flight in 2021, he took up contest winners and a cancer survivor.

Until Thursday, only 263 people had conducted a spacewalk, representing 12 countries. The Soviet Union’s Alexei Leonov kicked it off in 1965, followed a few months later by NASA’s Ed White.

Bomb blast hits Pakistan polio team amid national immunization drive 

Islamabad — Authorities in northwestern Pakistan said Monday that a roadside bomb explosion injured at least 10 people, including anti-polio vaccinators and police personnel escorting them.  

 

The bombing in the South Waziristan district near the border with Afghanistan targeted a convoy carrying polio workers and their guards on the opening day of a nationwide immunization campaign.  

 

Area security and hospital officials reported that three health workers and six security personnel were among the victims. No group immediately claimed responsibility for the violence in a region where security forces are fighting militants linked to the outlawed Pakistani Taliban.  

 

Last week, Pakistan reported its 17th wild poliovirus case of the year from Islamabad, saying it paralyzed a child and marked the first infection in 16 years in the national capital.  

 

Pakistani health officials said in the lead-up to Monday’s polio campaign that it is designed to vaccinate more than 33 million children under five in 115 districts nationwide. 

 

Muhammad Anwarul Haq, coordinator of the National Emergency Operations Center for Polio Eradication, stated that the immunization drive would primarily focus on districts where “the virus has been detected and the risk of continued transmission and spread is really high.” 

 

Haq encouraged all parents and caregivers to ensure their children get vaccinated, lamenting that “parents have not always welcomed and opened their doors to the vaccinators when they visit their homes.” 

 

Pakistan and Afghanistan, which reported nine paralytic polio cases so far in 2024, are the only two remaining polio-endemic countries globally. Polio immunization campaigns have long faced multiple challenges in both countries, such as security and vaccine boycotts, dealing setbacks to the goal of eradicating the virus from the world.

India isolates ‘suspected mpox case’

New Delhi — India reported Sunday that it had put a “suspected mpox case” into isolation, assuring that the world’s most populous nation had “robust measures” in place, the health ministry said in a statement.

There have been no confirmed cases of mpox in India, a country of 1.4 billion people.

“A young male patient, who recently traveled from a country currently experiencing mpox transmission, has been identified as a suspect case of mpox,” the health ministry said in a statement.

“The patient has been isolated in a designated hospital and is currently stable,” it said, adding the samples “are being tested to confirm the presence of mpox.”

It gave no further details of where he may have contracted the disease.

“There is no cause of any undue concern,” the statement added.

“The country is fully prepared to deal with such (an) isolated travel related case and has robust measures in place to manage and mitigate any potential risk.”

Mpox’s resurgence and the detection in the Democratic Republic of Congo of a new strain, dubbed Clade 1b, prompted the World Health Organization to declare its highest international alert level on August 14.  

Mpox has also been detected in Asia and Europe.

China plans to allow wholly foreign-owned hospitals in some areas

Beijing — China said Sunday it would allow the establishment of wholly foreign-owned hospitals in nine areas of the country including the capital, as Beijing tries to attract more foreign investment to boost its flagging economy.

In a document on the official website of China’s commerce ministry, it said the new policy was a pilot project designed to implement a pledge the ruling Communist Party’s Central Committee led by President Xi Jinping made at its July plenum meeting held roughly every five years.

“In order to … introduce foreign investment to promote the high-quality development of China’s medical-related fields, and better meet the medical and health needs of the people, it is planned to carry out pilot work of expanding opening-up in the medical field,” according to the document.

The project will allow the establishment of such hospitals in Beijing, Tianjin, Shanghai, Nanjing, Suzhou, Fuzhou, Guangzhou, Shenzhen and Hainan — all relatively wealthy cities or provinces in eastern or southern China.

The new policy excludes hospitals practicing traditional Chinese medicine and “mergers and acquisitions of public hospitals,” the document read, adding that the specific conditions, requirements and procedures for setting up such foreign-owned hospitals would be detailed soon.

The policy also allows companies with foreign investors to engage in the development and application of gene and human stem cell technologies for treatment and diagnosis in the pilot free-trade zones of Beijing, Shanghai, Guangdong, and Hainan.

This includes registration, marketing and production of products that can be bought nationwide, according to the document.

The removal of restrictions on foreign investment in these fields comes as the world’s second-largest economy faces growing headwinds with flagging foreign business sentiment, one of the issues threatening growth.

Drought forces Kenya’s Maasai, other cattle herders to consider fish, camels

KAJIADO, Kenya — The blood, milk and meat of cattle have long been staple foods for Maasai pastoralists in Kenya, perhaps the country’s most recognizable community. But climate change is forcing the Maasai to contemplate a very different dish: fish.

A recent yearslong drought in Kenya killed millions of livestock. While Maasai elders hope the troubles are temporary and they will be able to resume traditional lives as herders, some are adjusting to a kind of food they had never learned to enjoy.

Fish were long viewed as part of the snake family due to their shape, and thus inedible. Their smell had been unpleasant and odd to the Maasai, who call semi-arid areas home.

“We never used to live near lakes and oceans, so fish was very foreign for us,” said Maasai Council of Elders chair Kelena ole Nchoi. “We grew up seeing our elders eat cows and goats.”

Among the Maasai and other pastoralists in Kenya and wider East Africa — like the Samburu, Somali and Borana — cattle are also a status symbol, a source of wealth and part of key cultural events like marriages as part of dowries.

But the prolonged drought in much of East Africa left carcasses of emaciated cattle strewn across vast dry lands. In early 2023, the Kenya National Drought Management Authority said 2.6 million livestock had died, with an estimated value of 226 billion Kenya shillings ($1.75 billion).

Meanwhile, increasing urbanization and a growing population have reduced available grazing land, forcing pastoralists to adopt new ways to survive.

In Kajiado county near Kenya’s capital, Nairobi, the local government is supporting fish farming projects for pastoralists — and encouraging them to eat fish, too.

Like many other Maasai women, Charity Oltinki previously engaged in beadwork, and her husband was in charge of the family’s herd. But the drought killed almost 100 of their cows, and only 50 sheep of their 300-strong flock survived.

“The lands were left bare, with nothing for the cows to graze on,” Oltinki said. “So, I decided to set aside a piece of land to rear fish and monitor how they would perform.”

The county government supplied her with pond liners, tilapia fish fingerlings and some feed. Using her savings from membership in a cooperative society, Oltinki secured a loan and had a well dug to ease the challenge of water scarcity.

After six months, the first batch of hundreds of fish was harvested, with the largest selling for up to 300 Kenyan shillings each ($2.30).

Another member of the Maasai community in Kajiado, Philipa Leiyan, started farming fish in addition to keeping livestock.

“When the county government introduced us to this fish farming project, we gladly received it because we considered it as an alternative source of livelihood,” Leiyan said.

The Kajiado government’s initiative started in 2014 and currently works with 600 pastoralists to help diversify their incomes and provide a buffer against the effects of climate change. There was initial reluctance, but the number of participants has grown from about 250 before the drought began in 2022.

“The program has seen some importance,” said Benson Siangot, director of fisheries in Kajiado county, adding that it also addresses issues of food insecurity and malnutrition.

The Maasai share their love for cattle with the Samburu, an ethnic group that lives in arid and semi-arid areas of northern Kenya and speaks a dialect of the Maa language that the Maasai speak.

The recent drought has forced the Samburu to look beyond cattle, too — to camels.

In Lekiji village, Abdulahi Mohamud now looks after 20 camels. The 65-year-old father of 15 lost his 30 cattle during the drought and decided to try an animal more suited to long dry spells.

“Camels are easier to rear as they primarily feed on shrubs and can survive in harsher conditions,” he said. “When the pasture dries out, all the cattle die.”

According to Mohamud, a small camel can be bought for 80,000 to 100,000 Kenyan shillings ($600 to $770) while the price of a cow ranges from 20,000 to 40,000 ($154 to $300).

He saw the camel’s resilience as worth the investment.

In a vast grazing area near Mohamud, 26-year-old Musalia Piti looked after his father’s 60 camels. The family lost 50 cattle during the drought and decided to invest in camels that they can sell whenever they need cattle for traditional ceremonies. Cows among the Samburu are used for dowries.

“You have to do whatever it takes to find cattle for wedding ceremonies, even though our herds may be smaller nowadays,” said Lesian Ole Sempere, a 59-year-old Samburu elder. Offering a cow as a gift to a prospective bride’s parents encourages them to declare their daughter as “your official wife,” he said.

Pakistan hasn’t learned lessons from 2022 deadly floods, experts say

ISLAMABAD — Millions of people in Pakistan continue to live along the path of floodwaters, showing neither people nor the government have learned lessons from the 2022 devastating floods that killed 1,737 people, experts said Thursday, as an aid group said half of the 300 victims killed by rains since July are children.

Heavy rainfall is drenching those areas that were badly hit by the deluges two years ago.

The charity Save the Children said in a statement that floods and heavy rains have killed more than 150 children in Pakistan since the start of the monsoon season, making up more than half of all deaths in rain-affected areas.

The group said that 200 children have also been injured in Pakistan because of rains, which have also displaced thousands of people. Save the Children also said that people affected by floods were living in a relief camp in Sanghar, a district in the southern Sindh province, which was massively hit by floods two years ago.

“The rains and floods have destroyed 80% of cotton crops in Sanghar, the primary source of income for farmers, and killed hundreds of livestock,” the charity said, and added that it’s supporting the affected people with help from a local partner.

Khuram Gondal, the country director for Save the Children in Pakistan, said that children were always the most affected in a disaster.

“We need to ensure that the immediate impacts of the floods and heavy rains do not become long-term problems. In Sindh province alone, more than 72,000 children have seen their education disrupted,” he said.

Another charity, U.K.-based Islamic Relief, also said weeks of torrential rains in Pakistan have again triggered displacement and suffering among communities that were already devastated by the 2022 floods and are still in the process of rebuilding their lives and livelihoods.

Asif Sherazi, the group’s country director, said his organization is reaching out to flood-affected people.

There was no immediate response from the country’s ministry of climate change and national disaster management authority.

Pakistan has yet to undertake major reconstruction work because the government didn’t receive most of the funds out of the $9 billion that were pledged by the international community at last year’s donors’ conference in Geneva.

“We learned no lessons from that 2022 floods. Millions of people have built mud-brick homes on the paths of rivers, which usually remain dry,” said Mohsin Leghari, who served as irrigation minister years ago.

Leghari said that less rain is predicted for Pakistan for monsoon season compared with 2022, when climate-induced floods caused $30 billion in damage to the country’s economy.

“But the floodwater has inundated several villages in my own Dera Ghazi Khan district in the Punjab province,” Leghari said. “Floods have affected farmers, and my own land has once again come under the floodwater.”

Wasim Ehsan, an architect, said Pakistan was still not prepared to handle any 2022-like situation mainly because people ignore construction laws while building homes and even hotels in urban and rural areas.

He said the floods in 2022 caused damage in the northwest because people had built homes and hotels after slightly diverting a river. “This is reason that a hotel was destroyed by the Swat River in 2022,” he said.

New polio strain threatens setback to eradication in Nigeria

ABUJA, NIGERIA — Nigeria’s difficult victory over polio faces a challenge as the poliovirus type 2 variant reemerges and the nation considers new measures to tackle the outbreak.

Nigeria eradicated wild polio in 2020, but more than 50 cases of the poliovirus type 2 variant were reported between January and May. Authorities and global partners met Wednesday in Abuja with northern traditional leaders to strengthen efforts against the disease, particularly in under-immunized areas.

Bill Gates, a key global funder of Nigeria’s polio fight, said eradicating this strain is a top priority for the Gates Foundation.

“We do have this circulating variant, poliovirus type 2. The acronym is cVDPV2. … Unfortunately, it’s equally bad as the wild poliovirus,” Gates said. “It can paralyze or even kill children, and we still have work to do to get rid of this.”

Efforts focus on improving surveillance and expanding vaccination coverage. The World Health Organization noted setbacks earlier this year, stressing the need for continuing vigilance.

“We are facing the challenge of interrupting transmission of significant variant poliovirus type 2,” said Walter Kazadi Mulombo, WHO country representative to Nigeria. “We nearly got there several months ago but then we experienced some setbacks.”

Reluctance to take the vaccine, driven by religious and traditional beliefs, has hampered polio eradication efforts in Nigeria. However, northern traditional leaders have played a pivotal role in community outreach and health campaigns.

Muyi Aina, executive director of the Nigerian Primary Healthcare Development Agency, said traditional leaders have helped close the immunization gap in remote areas.

“The results we’re getting are due largely to the commitment received from our revered traditional leaders,” Aina said. “For example, we had a 57% reduction in pending noncompliance from the April campaign, and we were able to vaccinate an additional 117,000 zero-plus children [newborns and older] across 14 states with the help of the traditional leaders.”

Nigeria’s routine vaccination efforts, including recent campaigns to immunize against the human papilloma virus have been lauded. However, the resurgence of poliovirus type 2 highlights the need for sustained immunization, especially in vulnerable regions.

Cristian Munduate, the UNICEF country representative, called for more collaboration.

“We need to accelerate with polio, but we also need to accelerate in line with all these effects to link more routine immunization to reach those children,” Munduate said. “To work and strengthen primary health care, we are very committed to at least having one primary health care [worker] fully equipped per ward.”

Muhammadu Sa’ad Abubakar, the sultan of Sokoto, representing northern traditional rulers, reaffirmed their commitment to supporting vaccination efforts while thanking stakeholders.

“We are more concerned in the welfare of our people, so whoever is going to help us to help our people is part and parcel of us and is always welcomed,” Abubakar said.

Despite progress, the resurgence of poliovirus type 2 remains a serious threat. The Abuja meeting concluded with calls for stronger efforts, better surveillance, and continued collaboration between traditional leaders and health officials to ensure eradication.

First mpox vaccines due in DR Congo on Thursday

Kinshasa, Congo — The first delivery of almost 100,000 doses of mpox vaccines will arrive in the Democratic Republic of Congo on Thursday, the African Union’s health watchdog said.

The vast central Africa country of around 100 million people is at the epicenter of the mpox outbreak, with cases and deaths rising.

“We are very pleased with the arrival of this first batch of vaccines in the DRC,” Jean Kaseya, head of the Africa Centers for Disease Control and Prevention, told AFP, adding that more than 99,000 doses were expected.

More than 17,500 cases and 629 deaths have been reported in the country since the start of the year, according to the World Health Organization (WHO).

The vaccine doses will be transported onboard an airplane leaving the Danish capital Copenhagen on Wednesday evening and are due to arrive at Kinshasa’s international airport on Thursday at 1100 GMT.

 ‘Health war’

The Congolese National Institute of Public Health, which is in charge of managing the country’s mpox response, indicated that it was still waiting for details on the origin of the vaccines contained in the first delivery.

“Kinshasa is still waiting for documents from the Africa CDC that will provide information on these doses,” the institute’s director Dieudonne Mwamba Kazadi told AFP.

“We are in a health war against mpox. To face this disease, we need you,” Health Minister Samuel-Roger Kamba said on X on Tuesday.

In Africa, mpox is now present in at least 13 countries, including Burundi, Congo-Brazzaville and the Central African Republic, according to figures from the Africa CDC dated August 27.

On Wednesday, Guinea said it had recorded its first confirmed case of the disease, convening an emergency meeting in response.

A health official speaking on condition of anonymity told AFP that the case was discovered in a sub-prefecture close to the Liberian border.

Outside the continent, the virus has also been detected in Sweden, Pakistan and the Philippines.

The WHO said last week that the first vaccine doses would arrive in the DRC in the following days, with other deliveries to follow.

The WHO said at the end of August that around 230,000 MVA-BN vaccine doses produced by Danish drugmaker Bavarian Nordic were “imminently available to be dispatched to affected regions.”

Other countries have also promised to send vaccine doses to African nations.

Spain has promised 500,000 doses, with France and Germany each pledging 100,000.

The WHO declared an international emergency over mpox on August 14, concerned by the surge in cases of the new Clade 1b strain in the DRC that spread to nearby countries.

Both the Clade 1b and Clade 1a strains are present in the DRC.

The WHO’s Africa bureau said at the end of last month that 10,000 vaccine doses would be delivered to Nigeria — Bavarian Nordic vaccines donated by the United States.

This was the first African country to receive doses outside of clinical trials.

Formerly called monkeypox, the virus was discovered in 1958 in Denmark, in monkeys kept for research.

It was first discovered in humans in 1970 in what is now the DRC.

Mpox is caused by a virus transmitted to humans by infected animals but can also be passed from human to human through close physical contact.

The disease causes fever, muscular aches and large boil-like skin lesions.

Empty capsule to return to Earth soon; 2 astronauts will stay behind

CAPE CANAVERAL, Florida — Boeing will attempt to return its problem-plagued capsule from the International Space Station later this week — with empty seats.

NASA said Wednesday that everything is on track for the Starliner capsule to undock from the space station Friday evening. The fully automated capsule will aim for a touchdown in New Mexico’s White Sands Missile Range six hours later.

NASA’s two stuck astronauts, who flew up on Starliner, will remain behind at the orbiting lab. They’ll ride home with SpaceX in February, eight months after launching on what should have been a weeklong test flight. Thruster trouble and helium leaks kept delaying their return until NASA decided that it was too risky for them to accompany Starliner back as originally planned.

“It’s been a journey to get here, and we’re excited to have Starliner return,” said NASA’s commercial crew program manager Steve Stich.

NASA’s Butch Wilmore and Suni Williams will close the hatches between Starliner and the space station on Thursday. They are now considered full-time station crew members along with the seven others on board, helping with experiments and maintenance, and ramping up their exercise to keep their bones and muscles strong during their prolonged exposure to weightlessness.

To make room for them on SpaceX’s next taxi flight, the Dragon capsule will launch with two astronauts instead of the usual four. Two were cut late last week from the six-month expedition, which is due to blast off in late September. Boeing must vacate the parking place for SpaceX’s arrival.

Boeing encountered serious flaws with Starliner long before its June 5 liftoff on the long-delayed astronaut demo.

Starliner’s first test flight went so poorly in 2019 — the capsule never reached the space station because of software errors — that the mission was repeated three years later. More problems surfaced, resulting in even more delays and more than $1 billion in repairs.

The capsule had suffered multiple thruster failures and propulsion-system helium leaks by the time it pulled up at the space station after launch. Boeing conducted extensive thruster tests in space and on the ground, and contended the capsule could safely bring the astronauts back. But NASA disagreed, setting the complex ride swap in motion.

Starliner will make a faster, simpler getaway than planned, using springs to push away from the space station and then short thruster firings to gradually increase the distance. The original plan called for an hour of dallying near the station, mostly for picture-taking; that was cut to 20 or so minutes to reduce the stress on the capsule’s thrusters and keep the station safe.

Additional test firings of Starliner’s 28 thrusters are planned before the all-important descent from orbit. Engineers want to learn as much as they can since the thrusters won’t return to Earth; the section containing them will be ditched before the capsule reenters.

The stuck astronauts — retired Navy captains — have lived on the space station before and settled in just fine, according to NASA officials. Even though their mission focus has changed, “they’re just as dedicated for the success of human spaceflight going forward,” flight director Anthony Vareha said.

Their blue Boeing spacesuits will return with the capsule, along with some old station equipment.

NASA hired Boeing and SpaceX a decade ago to ferry its astronauts to and from the space station after its shuttles retired. SpaceX accomplished the feat in 2020 and has since launched nine crews for NASA and four for private customers.

Australian researchers plan new generation of biodegradable plastic

SYDNEY — Global concerns over plastic pollution and cuts to fossil fuel use are behind a new Australian-led initiative to develop a new generation of 100 percent compostable plastic. Experts estimate that more than 170 trillion pieces of plastic are floating in the world’s oceans. There are growing concerns about the impact of micro-plastics on health and the environment.    

The Bioplastics Innovation Hub aims to “revolutionize” plastic packaging by making biologically-made plastic that can break down in compost, land or water.  

The aim is to produce water bottles, for example, using bioplastics derived from waste products from the food industry. 

The green plastic scheme brings together the Commonwealth Scientific and Industrial Research Organization, the CSIRO – Australia’s national science agency – and Murdoch University in Perth in a multi-million dollar collaboration with industry partners. 

Andrew Whiteley, a CSIRO research program director, told VOA the technology could be ground-breaking.

“What we are really essentially doing is trying to phase out those fossil fuel plastics and bring in this new generation of bioplastics, which take over the roles of the plastics that we have already been using. So it is, really, just that switch over and going forward in a more sustainable way using these bioplastics.” 

Australian states and territories have been phasing out various plastics for several years. At the start of September 2024, more items have been banned in South Australia and Western Australia, including polystyrene containers and cups, plastic confetti, and plastic coffee cups and lids.

Chile, Kenya, India and New Zealand have also imposed restrictions on some single-use plastic products, such as bags or cutlery.

But there is a warning that the degradation of everyday plastic items, from packaging and in clothing, is creating microplastics that pollute the environment and pose a risk to health.    

Michelle Blewitt is the program director of the Australian Microplastic Assessment Project, a national citizen science organization, which has been monitoring microplastics.

She told the Australian Broadcasting Corp. the microplastic problem is getting worse.

“Micro plastics are particles that are less than 5mm in size and they can break up into smaller and smaller pieces until they become airborne.  So, they are found in our waterways and in the air and our homes and certainly on the beaches around our waterways as well.”

CSIRO scientists say the biodegradable plastic scheme is part of Australia’s commitment to the United Nations Global Treaty on plastic pollution.  It aims to be a legally binding international agreement between 175 countries to reduce the production and consumption of high-risk plastic.

About 98% of single-use plastic products are made from fossil fuels, according to the U.N.

Experts blame Africa’s mpox outbreaks on neglect, world’s inability to stop epidemics

LONDON — The growing mpox outbreaks in Africa that triggered the World Health Organization’s emergency declaration are largely the result of decades of neglect and the global community’s inability to stop sporadic epidemics among a population with little immunity against the smallpox-related disease, leading African scientists said Tuesday.

According to Dr. Dimie Ogoina, who chaired WHO’s mpox emergency committee, negligence has led to a new, more transmissible version of the virus emerging in countries with few resources to stop outbreaks.

Mpox, also known as monkeypox, had been spreading mostly undetected for years in Africa before the disease prompted the 2022 outbreak in more than 70 countries, Ogoina said at a virtual news conference.

“What we are witnessing in Africa now is different from the global outbreak in 2022,” he said. While that outbreak was overwhelmingly focused in gay and bisexual men, mpox in Africa is now being spread via sexual transmission as well as through close contact among children, pregnant women and other vulnerable groups.

And while most people over 50 were likely vaccinated against smallpox — which may provide some protection against mpox — that is not the case for Africa’s mostly young population, who Ogoina said were mostly susceptible.

Mpox belongs to the same family of viruses as smallpox but causes milder symptoms like fever and body aches. It mostly spreads through close skin-to-skin contact, including sex. People with more serious cases can develop prominent blisters on the face, hands, chest and genitals.

Earlier this month, WHO declared the surging mpox outbreaks in Congo and 11 other countries in Africa to be a global emergency.

On Tuesday, the Africa Centers for Disease Control and Prevention said there were more than 22,800 mpox cases and 622 deaths on the continent and that infections had jumped 200% in the last week. The majority of cases and deaths are in Congo, where most mpox infections are in children under 15.

Dr. Placide Mbala-Kingebeni, a Congolese scientist who helped identify the newest version of mpox, said diagnostic tests being used in the country did not always pick it up, making it hard to track the variant’s spread.

In May, Mbala-Kingebeni, who heads a lab at Congo’s National Institute for Biomedical Research, published research showing a new form of mpox that may be less deadly but more transmissible. The noted mutations suggested it was “more adapted to human transmission,” he said, but the lack of tests in Congo and elsewhere complicated efforts to monitor outbreaks.

The new variant has been detected in four other African countries as well as Sweden, where health officials said they have identified the first case of a person this month with the more infectious form of mpox. The person had been infected during a stay in Africa.

WHO said that available data to date does not suggest that the new form of mpox is more dangerous but that research is ongoing.

Marion Koopmans, a virologist at Erasmus Medical Centre in the Netherlands who has been studying mpox, said scientists were now seeing some significant impacts of the disease, noting that pregnant women were miscarrying or losing their fetuses and that some babies were being born infected with mpox.

Ogoina, a professor of infectious diseases at Niger Delta University in Nigeria, said that in the absence of vaccines and drugs, African health workers should focus on providing supportive care, like ensuring patients have enough to eat and are given mental health support, given the stigma that often comes with mpox.

“It’s very, very unfortunate that we have had mpox for 54 years and we are only now thinking about therapeutics,” he said.

Mbala-Kingebeni said strategies previously used to stop Ebola outbreaks in Africa might help, given the limited numbers of shots expected. He said authorities have estimated Africa needs about 10 million doses but might only receive about 500,000 — and it’s unclear when they might arrive.

“Finding a case and vaccinating around the case, like we did with Ebola, might help us target the hot spots,” he said.

Koopmans said that given the urgent need for vaccines in Africa, waiting for more doses to be produced was unrealistic.

“The short term really is about, who has vaccines and where are they to be best used next?” she said.

Spain’s health ministry announced Tuesday that it would dip into its mpox vaccine stockpile to donate 20% of its supply, about 500,000 doses, to African countries battling mpox.

“We consider it senseless to accumulate vaccines where they are not needed,” Spain’s health ministry said in a statement, adding Spain will recommend to the European Commission to propose that all member states also donate 20% of their vaccine stock.

Spain’s donation alone is more than what the European Union, vaccine Bavarian Nordic and the U.S. have pledged. Last week, Africa CDC said the EU and Bavarian Nordic had promised 215,000 mpox vaccines while the U.S. said it was donating 50,000 doses of the same vaccine to Congo. Japan has also donated some doses to Congo.

Meanwhile, the U.S. on Tuesday donated 10,000 doses of mpox vaccines to Nigeria where mpox has been common, making the vaccines the first to arrive in Africa since the global emergency was declared. The country has had a few dozen cases this year.

Health authorities begin large-scale polio vaccinations in war-ravaged Gaza

DEIR AL-BALAH, Gaza Strip — Palestinian health authorities and United Nations agencies on Sunday began a large-scale campaign of vaccinations against polio in the Gaza Strip, hoping to prevent an outbreak in the territory that has been ravaged by the ongoing Israel-Hamas war.

Authorities plan to vaccinate children in central Gaza until Wednesday before moving on to the more devastated northern and southern parts of the strip. The campaign began with a small number of vaccinations on Saturday and aims to reach about 640,000 children.

The World Health Organization said Thursday that Israel has agreed to limited pauses in the fighting to facilitate the campaign. There were initial reports of Israeli strikes in central Gaza early Sunday, but it was not immediately known if anyone was killed or wounded.

Hospitals in Deir al-Balah and Nuseirat confirmed that the campaign had begun early Sunday. Israel said Saturday that the vaccination program would continue through September 9 and last eight hours a day.

Gaza recently reported its first polio case in 25 years — a 10-month-old boy, now paralyzed in the leg. The World Health Organization says the presence of a paralysis case indicates there could be hundreds more who have been infected but aren’t showing symptoms.

Most people who have polio do not experience symptoms, and those who do usually recover in a week or so. But there is no cure, and when polio causes paralysis, it is usually permanent. If the paralysis affects breathing muscles, the disease can be fatal.

The vaccination campaign faces a host of challenges, from ongoing fighting to devastated roads and hospitals shut down by the war. Around 90% of Gaza’s population of 2.3 million people have been displaced within the besieged territory, with hundreds of thousands crammed into squalid tent camps.

Health officials have expressed alarm about disease outbreaks as uncollected garbage has piled up and the bombing of critical infrastructure has sent putrid water flowing through the streets. Widespread hunger has left people even more vulnerable to illness.

“We escaped death with our children, and fled from place to place for the sake of our children, and now we have these diseases,” said Wafaa Obaid, who brought her three children to the Al-Aqsa Martyrs Hospital in Deir al-Balah to get the vaccinations.

Ammar Ammar, a spokesperson for the U.N. children’s agency, said it hopes both parties adhere to a temporary truce in designated areas to enable families to reach health facilities.

“This is a first step,” he told The Associated Press. “But there is no alternative to a cease-fire because it’s not only polio that threatens children in Gaza, but also other factors, including malnutrition and the inhuman conditions they are living in.”

The vaccinations will be administered at roughly 160 sites across the territory, including medical centers and schools. Children under 10 will receive two drops of oral polio vaccine in two rounds, the second to be administered four weeks after the first.

Israel allowed around 1.3 million doses to be brought into the territory last month, which are now being held in refrigerated storage in a warehouse in Deir al-Balah. Another shipment of 400,000 doses is set to be delivered to Gaza soon.

The polio virus that triggered this latest outbreak is a mutated virus from an oral polio vaccine. The oral polio vaccine contains weakened live virus and in very rare cases, that virus is shed by those who are vaccinated and can evolve into a new form capable of starting new epidemics.

The war in Gaza began when Hamas-led militants stormed into Israel on October 7, killing some 1,200 people, mostly civilians, and abducting around 250 hostages. Around 100 remain in captivity, about a third of whom are believed to be dead.

Israel’s retaliatory offensive has killed over 40,000 Palestinians, according to the Gaza Health Ministry, which does not say whether those killed were fighters or civilians. The war has caused vast destruction across the territory, with entire neighborhoods wiped out and critical infrastructure heavily damaged.

The United States, Egypt and Qatar have spent months trying to broker a cease-fire and the release of the remaining hostages, but the talks have repeatedly stalled and a number of sticking points remain.

Newborn rattlesnakes at Colorado ‘mega den’ make their live debut

CHEYENNE, Wyoming — A “mega den” of hundreds of rattlesnakes in Colorado is getting even bigger now that late summer is here and babies are being born.

Thanks to livestream video, scientists studying the den on a craggy hillside in Colorado are learning more about these enigmatic — and often misunderstood — reptiles. They’re observing as the youngsters, called pups, slither over and between adult females on lichen-encrusted rocks.

The public can watch too on the Project RattleCam website and help with important work including how to tell the snakes apart. Since researchers put their remote camera online in May, several snakes have become known in a chat room and to scientists by names including “Woodstock,” “Thea” and “Agent 008.”

The live feed, which draws as many as 500 people at a time online, on Thursday showed a tangle of baby snakes with tiny nubs for rattles. They have a lot of growing to do: A rattlesnake adds a rattle segment each time it sheds its skin a couple times a year, on average.

The project is a collaboration between California Polytechnic State University in San Luis Obispo, snake removal company Central Coast Snake Services and Dickinson College in Carlisle, Pennsylvania.

By involving the public, the scientists hope to dispel the idea that rattlesnakes are usually fierce and dangerous. In fact, experts say they rarely bite unless threatened or provoked and often are just the opposite. 

Rattlesnakes are not only among the few reptiles that care for their young. They even care for the young of others. The adults protect and lend body heat to pups from birth until they enter hibernation in mid-autumn, said Max Roberts, a CalPoly graduate student researcher.

“We regularly see what we like to call ‘babysitting,’ pregnant females that we can visibly see have not given birth, yet are kind of guarding the newborn snakes,” Roberts said Wednesday.

As many as 2,000 rattlesnakes spend the winter at the location on private land, which the researchers are keeping secret to discourage trespassers. Once the weather warms, only pregnant females remain while the others disperse to nearby territory.

This year, the scientists keeping watch over the Colorado site have observed the rattlesnakes coil up and catch water to drink from the cups formed by their bodies. They’ve also seen how the snakes react to birds swooping in to try to grab a scaly meal.

The highlight of summer is in late August and early September when the rattlesnakes give birth over a roughly two-week period.

“As soon as they’re born, they know how to move into the sun or into the shade to regulate their body temperature,” Roberts said.

There are 36 species of rattlesnakes, most of which inhabit the U.S. They range across nearly all states and are especially common in the Southwest. Those being studied now are prairie rattlesnakes, which can be found in much of the central and western U.S. and into Canada and Mexico.

Like other pit viper species but unlike most snakes, rattlesnakes don’t lay eggs. Instead, they give birth to live young. Eight is an average-size brood, with the number depending on the snake’s size, according to Roberts.

Roberts is studying how temperature changes and ultraviolet sunlight affect snake behavior. Another graduate student, Owen Bachhuber, is studying the family and social relationships between rattlesnakes.

The researchers watch the live feed all day.

“We are interested in studying the natural behavior of rattlesnakes, free from human disturbance. What do rattlesnakes actually do when we’re not there?” Roberts said.

Now that the Rocky Mountain summer is cooling, some males have been returning. By November, the camera running on solar and battery power will be turned off until next spring, when the snakes will re-emerge from their “mega den.”

Bird species extinct in Europe returns, and humans must help it migrate

PATERZELL, Germany — How do you teach a bird how, and where, to fly?

The distinctive northern bald ibis, hunted essentially to extinction by the 17th century, was revived by breeding and rewilding efforts over the last two decades. But the birds — known for their distinctive black-and-iridescent green plumage, bald red head and long curved beak — don’t instinctively know which direction to fly to migrate without the guidance of wild-born elders. So a team of scientists and conservationists stepped in as foster parents and flight instructors.

“We have to teach them the migration route,” said biologist Johannes Fritz.

The northern bald ibis once soared over North Africa, the Arabian Peninsula and much of Europe, including southern Germany’s Bavaria. The migratory birds were also considered a delicacy, and the bird, known as the Waldrapp in German, disappeared from Europe, though a few colonies elsewhere survived.

The efforts of Fritz and the Waldrappteam, a conservation and research group based in Austria, brought the Central European population from zero to almost 300 since the start of their project in 2002.

The feat moved the species from a “critically endangered” classification to “endangered” and, Fritz says, is the first attempt to reintroduce a continentally extinct migratory bird species.

But while northern bald ibises still display the natural urge to migrate, they don’t know which direction to fly without the guidance of wild-born elders. The Waldrappteam’s early reintroduction attempts were largely unsuccessful because, without teaching the birds the migration route, most disappeared soon after release. Instead of returning to suitable wintering grounds such as Tuscany, Italy, they flew in different directions and ultimately died.

So the Waldrappteam stepped in as foster parents and flight instructors for the Central European population, which was made up of descendants from multiple zoo colonies and released into the wild in the hopes of creating a migratory group. This year marks the 17th journey with human-led migration guides, and the second time they’ve been forced to pilot a new route to Spain due to climate change.

To prepare them for travel, the chicks are removed from their breeding colonies when they are just a few days old. They are taken to an aviary that’s overseen by the foster parents in the hopes of “imprinting” — when the birds will bond with those humans to ultimately trust them along the migration route.

Barbara Steininger, a Waldrapp team foster mother, said she acts like “their bird mom.”

“We feed them, we clean them, we clean their nests. We take good care of them and see that they are healthy birds,” she said. “But also we interact with them.”

Steininger and the other foster parents sit on the back of a microlight aircraft, waving and shouting encouragement through a bullhorn as it flies through the air.

It’s a bizarre scene: The aircraft looks like a flying go-kart with a giant fan on the back and a yellow parachute keeping it aloft. Still, three dozen birds follow the contraption, piloted by Fritz, as it sails over alpine meadows and foothills.

Fritz was inspired by “Father Goose” Bill Lishman, a naturalist who taught Canadian geese to fly alongside his ultra-light plane beginning in 1988. He later guided endangered whooping cranes through safe routes and founded the nonprofit “Operation Migration.” Lishman’s work prompted the 1996 movie “Fly Away Home” but features a young girl as the geese’s “mother.”

Like Lishman, Fritz and his team’s efforts have worked. The first bird independently migrated back to Bavaria in 2011 from Tuscany. More have flown the route that’s upward of 550 kilometers (342 miles) each year, and the team hopes the Central European population will be more than 350 birds by 2028 and become self-sustaining.

But the effects of climate change mean the Waldrapp are migrating later in the season now, which forces them to cross the Alps in colder, more dangerous weather — without the aid of warm currents of air, known as thermals, that rise upward and help the birds soar without expending extra energy.

In response, the Waldrappteam piloted a new route in 2023, from Bavaria to Andalusia in southern Spain.

This year, the route is roughly 2,800 kilometers (1,740 miles) — some 300 kilometers (186 miles) longer than last year’s path. Earlier this month from an airfield in Paterzell, in upper Bavaria, the team guided 36 birds along one stage through bright blue skies and a tailwind that increased their speed.

The entire journey to Spain could take up to 50 days and end in early October. But Fritz says the effort is bigger than just the northern bald ibises: It’s about paving the way for other threatened migratory species to fly.

Doctor who helped Agent Orange victims wins Magsaysay Award

MANILA, Philippines — A Vietnamese doctor who has helped seek justice for victims of the powerful defoliant dioxin “Agent Orange” used by U.S. forces during the Vietnam War is among this year’s winners of the Ramon Magsaysay Awards — regarded as Asia’s version of the Nobel Prizes. 

Other winners announced on Saturday were a group of doctors who struggled to secure adequate health care for Thailand’s rural poor, an Indonesian environmental defender, a Japanese animator who tackles complex issues for children, and a Bhutanese academician promoting his country’s cultural heritage to help current predicaments. 

First given in 1958, the annual awards are named after a Philippine president who died in a 1957 plane crash, and honor “greatness of spirit” in selfless service to people across Asia. 

“The award has celebrated those who challenge the status quo with integrity by courageously confronting systemic injustices, transform critical sectors through groundbreaking solutions that drive societal progress, and address pressing global issues with unwavering resilience,” said Susanna B. Afan, president of the award foundation. 

Vietnamese doctor Nguyen Thi Ngoc Phuong carried out extensive research into the devastating and long-term effects of Agent Orange. She said she first encountered it in the late 1960s as a medical intern when she helped deliver babies with severe birth defects as a result of the lingering effect of highly toxic chemical, according to the awards body. 

“Her work serves as a dire warning for the world to avoid war at all costs as its tragic repercussions can reach far into the future,” the Magsaysay foundation said. “She offers proof that it can never be too late to right the wrongs of war and gain justice and relief for its hapless victims.” 

American forces used Agent Orange during the Vietnam War to defoliate Vietnamese jungles and destroy crops for the Vietnamese Communists, or Viet Cong, who fought against South Vietnam and the United States. 

Between 1962 and 1971, the U.S. military sprayed roughly 11 million gallons of the chemical agent dioxin used in Agent Orange across large swaths of southern Vietnam. Dioxin stays in the soil and in the sediment of lakes and rivers for generations. It can enter the food supply through the fat of fish and other animals. 

Vietnam says as many as 4 million citizens were exposed to the herbicide and as many as 3 million have suffered illnesses from it, including the children of people exposed during the war. 

Indonesian Farwiza Farhan won the award for helping lead a group to protect the Leuser Ecosystem, a 2.6-million-hectare forest on Sumatra Island in his country’s Aceh province where some of the world’s most highly endangered species have managed to survive, the foundation said. 

Her group helped win a court verdict that led to $26 million in fines against a palm oil company that burned forests and stopped a hydroelectric dam that would have threatened the elephant’s habitat, the foundation said. 

Miyazaki Hayao, a popular animator in Japan, was cited by the awards body as a co-founder in 1985 of Studio Ghibli, a leading proponent of animated films for children. Three Ghibli productions were among Japan’s 10 top-grossing films. 

“He tackles complicated issues, using his art to make them comprehensible to children, whether it be about protecting the environment, advocating for peace or championing the rights and roles of women in society,” the foundation said. 

The Rural Doctors Movement, a group of Thai physicians, won the award for their “decades of struggle … to secure adequate and affordable health care for their people, especially the rural poor,” the foundation said. 

“By championing the rural poor, the movement made sure to leave no one behind as the nation marches forward to greater economic prosperity and modernization,” it said. 

Karma Phuntsho from Bhutan, a former Buddhist monk and an Oxford-educated scholar, was cited by the awards body for his academic works in the field of Buddhism and Bhutan’s rich history and cultural heritage that were being harnessed to address current and future problems in his country, including unemployment and access to high-quality education. 

The winners will be presented with their awards and a cash prize on November 16 at the Metropolitan Theater in Manila.
