LOISABA CONSERVANCY, Kenya — Conservationists in Kenya are celebrating as rhinos were returned to a grassy plateau that hasn’t seen them in decades.

The successful move of 21 eastern black rhinos to a new home will give them space to breed and could help increase the population of the critically endangered animals. It was Kenya’s biggest rhino relocation ever.

The rhinos were taken from three parks that are becoming overcrowded to the private Loisaba Conservancy, where herds were wiped out by poaching decades ago.

“It’s been decades since rhinos roamed here, almost 50 years ago,” said Loisaba security manager Daniel Ole Yiankere. “Their numbers were severely impacted by poaching. Now, our focus is on rejuvenating this landscape and allowing rhinos to breed, aiming to restore their population to its former splendor.”

Moving rhinos safely is a serious challenge. The 18-day exercise involved tracking the rhinos using a helicopter and then shooting them with tranquilizer darts. Then the animals — which weigh about a ton each — have to be loaded into the back of a truck for the move.

Disaster nearly struck early in the relocation effort, when a tranquilized rhino stumbled into a creek. Veterinarians and rangers held the rhino’s head above water with a rope to stop it from drowning while a tranquilizer reversal drug took effect, and the rhino was released.

Some of the rhinos were transferred from Nairobi National Park and made a 300-kilometer trip. Others came from two parks closer to Loisaba.

Rhinos are generally solitary animals and are at their happiest in large territories. As numbers in the three parks where the rhinos were moved from have increased, wildlife officials decided to relocate some in the hope that they will be happier and more likely to breed.

David Ndere, an expert on rhinos at the Kenya Wildlife Service, said their reproduction rates decrease when there are too many in a territory.

“By removing some animals, we expect that the rhino population in those areas will rise up,” Ndere said. “And then we reintroduce that founder population of at least 20 animals into new areas.”

Loisaba Conservancy said it has dedicated around 25,000 hectares to the new arrivals, which are a mix of males and females.

Kenya has had relative success in reviving its black rhino population, which dipped from around 20,000 in the 1970s to below 300 in the mid-1980s because of poaching, according to conservationists, raising fears that the animals might be wiped out completely in the country. Kenya now has around 1,000 black rhinos, the third biggest population behind South Africa and Namibia.

There are just over 6,400 wild black rhinos left in the world, all of them in Africa, according to the Save the Rhino organization.

Tom Silvester, the CEO of Loisaba Conservancy, said Kenya’s plan is to get its black rhino numbers to 2,000 over the next decade.

“Once we have 2,000 individuals, we will have established a population that will give us hope that we have brought them back from extinction,” he said.

Kenyan authorities say they have relocated more than 150 rhinos in the last decade.

An attempt to move 11 rhinos in 2018 ended in disaster when all of the animals died shortly after moving.

Ten of the rhinos died from stress, dehydration and starvation intensified by salt poisoning as they struggled to adjust to saltier water in their new home, investigations found. The other one was attacked by a lion.

Since then, new guidelines have been created for the capture and moving of rhinos in Kenya. Silvester said tests have been conducted on the water quality at Loisaba.

Kenya is also home to the last two remaining northern white rhinos on the planet. Researchers said last month they hope they might be able to save that subspecies after creating an embryo in a lab from an egg and sperm previously collected from white rhinos and transferring it into a surrogate female black rhino. The pregnancy was discovered in a postmortem after the surrogate died of an infection following a flood.

RIO DE JANEIRO — The small team of state public health workers slalomed between auto parts strewn across a Rio de Janeiro junkyard, looking for standing water where mosquitoes might have laid their eggs.

They were part of nationwide efforts to curtail a surge in Brazil of the mosquito-borne illness of dengue fever during the country’s key tourist season that runs through the end of February.

Paulo Cesar Gomes, a 56-year-old entomologist, found some mosquito larvae swimming in shallow rainwater inside a car bumper.

“We call this type of location a strategic point” because of the high turnover in items converging from all over, he said. “It’s difficult not to have mosquitoes here.”

Earlier in the month, just days before Rio kicked off its world-famous Carnival festivities, the city joined several states and the country’s capital in declaring a public health epidemic over this year’s greater-than-normal number of cases of dengue.

“We had more cases in January than any other January,” Ethel Maciel, head of health surveillance at Brazil’s Health Ministry, said in an interview with The Associated Press.

So far this year, Brazil has recorded 512,000 cases nationwide, including both confirmed and likely cases — nearly four times more than those registered in the same period a year ago.

There have been 425 deaths under investigation for dengue so far this year, with 75 confirmed, as compared with just over 1,000 for all of 2023.

Dengue is a viral infection transmitted to humans through the bite of infected mosquitoes. Frequent rains and high temperatures, which accelerate the hatching of mosquito eggs and the development of larvae, make the famously hot city of Rio especially susceptible to outbreaks.

Many who are infected never develop symptoms, but dengue can cause high fever, headache, body aches, nausea and a rash, according to the World Health Organization. While most get better after a week or so, some develop a severe form that requires hospitalization and can be fatal.

Health workers like Gomes, equipped with masks and plastic gloves, meticulously combed the junkyard on a hot morning, gently kicking and shaking piled up auto parts looking for any trace of the Aedes aegypti mosquito that can spread dengue.

Whenever he saw standing water Gomes grabbed a hand pipette out of his bag and looked for larvae, which he collected in a white plastic container. Captured mosquitos and larvae are kept alive and brought to a city laboratory to be tested for dengue.

At locations with positive tests, health agents spray the walls with a product that kills mosquitoes and then monitor the location for weeks.

Maciel, from the Health Ministry, said the first warning about a possible epidemic came in September.

Brazil’s leading research institute, the state-funded Oswaldo Cruz Foundation, or Fiocruz, came up with several scenarios indicating that Brazil could have as many as 4.2 million cases this year, up from 1.6 million in 2023.

Maciel said the surge is due to excessive heat and intense rain, both possible effects of climate change or El Niño, a natural, temporary and occasional warming of part of the Pacific that shifts weather patterns across the globe.

Maciel also cited the circulation of four dengue virus serotypes at the same time, one of which authorities had not seen in 15 years.

In Rio, more than 80% of mosquito breeding sites are located in residential properties, health officials say. So, efforts to combat dengue must start in homes, and raising awareness is key, said Mário Sérgio Ribeiro, a health surveillance official for Rio de Janeiro state.

State officials launched a “10 minutes that save lives” initiative to encourage residents to inspect their homes, offices and places of worship for any standing water.

Health workers and volunteers went door to door, pacing up and down the narrow streets of Rio’s Tabajara working-class neighborhood, or favela, to spread the word. They distributed leaflets and climbed on rooftops, looking for containers with rainwater.

One elderly woman, Vilza da Costa, told the AP she believes she contracted the disease.

“It started with a fever, then my body was itching all over, weakness, and a lot of pain. I was in a very bad way,” she said. “There are a lot of mosquitoes here.”

During Carnival, which ended Wednesday, health employees welcomed visitors with free repellent. A van with a giant crossed off mosquito and the words “Against Dengue Everyday” opened and closed the parades several nights, for millions of TV viewers to see.

Maciel said the effect of Carnival will not be known for another week. Even though dengue is not transmissible from person to person, increased tourism can boost the spread of the disease to locations that had not been affected.

It’s not clear if the cases have reached a peak and now “are going to start going down, or if the worst-case scenario is indeed happening,” Maciel said.

TAIPEI, TAIWAN — China’s inauguration of a new scientific research station in Antarctica last week has renewed debate about the purpose and impact of the rapid expansion of Chinese presence on the continent. 

Situated on Inexpressible Island near the Ross Sea, Qinling Station is China’s fifth scientific outpost and third research station on the continent that can operate year around. The station covers 5,244 square meters and can house up to 80 people during summer months, according to Chinese state broadcaster CGTN.

Qinling Station is near the U.S. McMurdo Station and just south of Australia and a  Center for Strategic and International Studies report published last April said its position could allow China to “collect signals intelligence from U.S.-allied Australia and New Zealand” as well as gather “telemetry data on rockets launching from newly established space facilities in both countries.” 

Some analysts say while Qinling Station is built for scientific purposes, some of its capabilities may be “inherently dual-use.”

“China can potentially leverage some of those resources and capabilities for military or intelligence gathering purposes,” Brian Hart, a fellow with the China Power Project at CSIS, told VOA by phone. 

He said China continues build more Antarctic research bases because it views the icy continent as part of the “strategic frontiers.” 

“Since it is an area that is further from China’s immediate periphery, Beijing wants to be on the cutting edge and be perceived as a global leader that’s on par with the U.S.,” Hart said, adding that China’s long-term goal is to have a voice in Antarctic governance by cementing a foothold there by establishing scientific research bases. 

In response to concerns about China potentially collecting intelligence on Australia and New Zealand through the station, the Chinese Foreign Ministry said the base is built and operated “in full compliance with international rules and procedures.” 

“The station will contribute to humanity’s scientific understanding of the Antarctic, provide a platform for joint scientific exploration and coordination between China and other countries and help advance peace and sustainable development in the region,” Chinese Foreign Ministry spokesperson Wang Wen-bin said during the daily press conference February 7. 

Despite Beijing’s reiteration that the station abides by the rules of the Antarctic Treaty, which outlaws the military use of the continent, some experts say China’s pattern of building its research stations across Antarctica raises legitimate questions about its significant presence on the continent. 

China’s pattern of building Antarctic research bases “raises questions about whether it is committed to the principles of the Antarctic treaty and whether it plans to potentially assert a claim to Antarctica,” Donald Rothwell, professor of international law at Australian National University, told VOA by phone. 

Since China has expressed the ambition to become a great polar power, Rothwell said China’s rapid expansion of research bases in Antarctica aligns with that goal.

 “Over the last decade, China has sought to be seen as a serious state actor in polar affairs,” he said. 

China is gaining “[credibility as a serious Antarctic state through its scientific research program and its engagement in the Antarctic Treaty system,” Rothwell added. 

The day that China announced the opening of Qinling Station, Chinese President Xi Jinping said the completion of the building of the research base would “provide a strong guarantee for scientists in China and around the world to continue to explore the mysteries of nature and bravely ascend the peak of science.” 

He also called for “better understanding, protection, and utilization of the polar regions to make new and greater contributions to the benefit of humanity and the building of a community with a shared future for humanity.”  

While the Qinling Station has begun operation, Hart said more elements with potential dual-use capabilities may be added in the future.

“The capacity for this station to support habitation is already up and running but there are more elements of the overall facility that will be built out in the future,” he told VOA. 

“The main one for potential dual-use applications is the antennas and other electronic equipment that can support communication with China’s satellites,” Hart said. 

In a 2022 report on China’s military and security developments, the U.S. Department of Defense said  that China’s “strategy for Antarctica includes the use of dual-use technologies, facilities, and scientific research, which are likely intended, at least in part, to improve PLA [People’s Liberation Army] capabilities.” 

The report also indicated that China’s facilities on the continent can be reference stations for its dual-use BeiDou satellite navigation network, which is Beijing’s alternative to the U.S.-controlled global positioning system.  

Hart said that while Chinese scientists are doing legitimate work in Antarctica that should not be curtailed, “it’s important to emphasize what kind of capabilities” their research stations will have and how those capabilities could be beneficial to the Chinese government and Chinese military.

“It’s important that Antarctica remains a nonmilitarized space,” he told VOA. 

Some analysts say a way to ensure Antarctica remains nonmilitarized and that the interests of Antarctic Treaty members are guaranteed is to rely on existing inspection regimes. 

There should be “a concerted effort to use the inspection regimes that are available in Antarctica to ensure that facilities are not used for military activities or contrary to the Antarctic Treaty,” Tony Press, an expert on Antarctic affairs at the University of Tasmania, told VOA in a video interview.

GENEVA — Health agencies are urging governments and civil society to step up action to eliminate cervical cancer, a vaccine-preventable disease that kills a woman every two minutes, mostly in low- and middle-income countries.  

“It is the fourth-most common cancer among women worldwide. It is also one of the few types of cancer that can be prevented by a vaccine,” said Herve Verhoosel, spokesperson for Unitaid, an organization that provides affordable lifesaving health products for people in low- and middle-income countries. 

“Vaccination against human papillomavirus, the leading cause of cervical cancer, together with HPV screening and treatment, is a proven path to elimination,” Verhoosel said Tuesday in advance of the first global forum on elimination of cervical cancer. 

The forum, which takes place from March 5 to 7 in Cartagena, Colombia, is hosted by Spain, Colombia and nine leading development and health agencies. 

348,000 women died in 2020

Verhoosel said, “The forum offers a watershed moment for the world to collectively accelerate progress on a groundbreaking promise made in 2020, when nearly 200 countries signed on to the WHO’s global strategy to eliminate cervical cancer.” 

The World Health Organization, Unitaid and other aid agencies provided the statistics on case rates. The WHO estimates 348,000 women died of cervical cancer in 2020, 90% of them from low- and middle-income countries. It warns annual deaths from cervical cancer will likely reach 410,000 by 2030 “if we do not change course.” 

To put countries on the path to elimination, the WHO has set three targets: It calls for 90% of girls to be vaccinated with the HPV vaccine by age 15; 70% of women to be screened with a high-performance test by age 35 and again at 45; and for 90% of women with cervical disease to receive treatment. 

The WHO says sub-Saharan Africa has the highest cervical cancer burden globally. It notes the HIV epidemic has worsened the situation because the common HPV virus is sexually transmitted. 

Prebo Barango, cross-cutting specialist on noncommunicable diseases and special initiatives at the WHO, explains that the prevalence of cervical cancer in some countries “demonstrates the inequity of access to prevention and health care as well as social and economic deprivation” in the affected communities. 

He stressed the importance of vaccinating young girls and making access to screening and early treatment for older women more widely available. 

“It is not an either-or approach,” he said. He notes, however, that “access to screening and treatment has been very, very low because most countries have no coverage for these procedures.” 

Barriers to vaccination

The WHO reports that only one in five adolescent girls has been vaccinated against HPV, despite the vaccine’s proven efficacy. Barango explained that a key constraint related to its use is that the recommended age of 14 for receiving the vaccine “falls outside of the normal vaccination age for children.” 

Besides that, he said, “During COVID-19 there was a significant drop in the uptake of these vaccines because schools were closed” and many health facilities were focused on dealing with the pandemic. 

The World Health Organization says cost effective and evidence-based tools for screening and treatment are available. Despite this, it says barriers and inequities in the hardest-hit areas remain unacceptably high. The WHO notes that fewer than 5% of women in low- and middle-income countries are ever screened for cervical cancer. 

Unitaid spokesperson Verhoosel observed that the WHO’s recommendation of a one-dose HPV vaccine instead of the previous two-dose recommendation could prove to be a game changer. 

“A one-dose HPV vaccine opens new opportunities to reach more girls worldwide and will significantly reduce costs and logistical barriers,” he said. 

The nonprofit GAVI vaccine alliance is providing millions of low-cost HPV vaccine doses to developing countries at the affordable price of around $5.00 per dose. And Unitaid says that, together with its partners, it “has secured agreements that have reduced the price of HPV tests by nearly 40%.”

Bangkok — Bangkok city employees have been told to work from home to avoid harmful air pollution, as a layer of noxious haze blanketed the Thai capital Thursday.

City authorities asked for cooperation from employers to help workers in the city of some 11 million people avoid the pollution, which is expected to last into Friday.

The air monitoring website IQAir ranked Bangkok among the 10 most polluted cities in the world Thursday morning.

Levels of the most dangerous PM2.5 particles — so tiny they can enter the bloodstream — were more than 15 times the World Health Organization’s annual guideline, according to IQAir.

Bangkok governor Chadchart Sittipunt said late Wednesday that all city employees would work from home Thursday and Friday.

“I would like to ask for cooperation from the BMA network of about 151 companies and organizations, both government offices and the private sector,” he said in a statement, adding that more than 60,000 people were affected.

BMA is an abbreviation for the Bangkok Metropolitan Administration.

Chadchart said at least 20 of Bangkok’s 50 districts were expected to have unhealthy levels of PM2.5 particles, and the problem would linger because of calm weather.

Air quality in Thailand regularly plummets in the early months of the year as smoke from farmers burning stubble in the fields adds to industrial emissions and vehicle exhaust fumes.

Bangkok and the northern city of Chiang Mai ranked among the most polluted cities in the world on a number of days last year.

A public health crisis is brewing over the problem, with at least two million people in Thailand needing medical treatment because of pollution in 2023.

The government of Prime Minister Srettha Thavisin, which took over in August, has promised to make tackling air pollution a “national agenda,” and a draft Clean Air Act was endorsed by his Cabinet last month.

But the problem persists, and a court in Chiang Mai last month ordered the government to come up with an urgent plan to tackle air pollution within 90 days.

SYDNEY — Using satellite technology and sophisticated machine learning, a team led by marine experts in Australia have created new maps of the world’s coral reefs.

The scientists discovered there are more coral reefs around the world than previously documented, with Indonesia, Australia and the Philippines having the most coral reefs. 

Over 100 trillion pixels of data were examined. The result is a high-resolution map that gives fresh insight into the distribution of reefs.

The Allen Coral Atlas initiative has identified approximately 348,000 square kilometers of shallow coral reefs globally to depths of up to 30 meters, an increase from previous estimates.

Experts hope the study will allow politicians, scientists and environmentalists to better understand and manage coral reef systems.

Coral reefs face a range of threats, including climate change, overfishing and pollution.

Australia’s Great Barrier Reef — the only living thing visible from space – is also undermined by industrialization and coral-eating crown of thorns starfish.

“In Australia we, kind of, had a reasonable idea of where a lot of our reefs might have been,” Mitchell Lyons from the School of the Environment at Australia’s University of Queensland told the Australian Broadcasting Corp. “But for some jurisdictions across the southwest Pacific or Indonesia, Philippines, there were not very good, consistent maps of where coral reefs were.  I guess the advantage of having these consistent maps all over the globe is that we can start to report and account and, I guess, conserve.”

The maps are publicly available through the Allen Coral Atlas and Google Earth Engine.

The project receives funding from a company founded by the Microsoft co-founder Paul Allen and managed by Arizona State University in partnership with conservationists and the University of Queensland.

The full study was published in the journal Cell Reports Sustainability.  It states that “coral reefs possess a quarter of all marine life and contribute to the well-being and livelihoods of a billion people worldwide.”

CAPE CANAVERAL, Florida — A moon lander built by Houston-based aerospace company Intuitive Machines was launched from Florida early Thursday on a mission to conduct the first U.S. lunar touchdown in more than a half century and the first by a privately owned spacecraft.

The company’s Nova-C lander, dubbed Odysseus, lifted off shortly after 1 a.m. EST (0600 GMT) atop a Falcon 9 rocket flown by Elon Musk’ SpaceX from NASA’s Kennedy Space Center in Cape Canaveral.

A live NASA-SpaceX online video feed showed the two-stage, 25-story rocket roaring off the launch pad and streaking into the dark sky over Florida’s Atlantic coast, trailed by a fiery yellowish plume of exhaust.

The launch, previously set for Wednesday morning, was postponed for 24 hours because of irregular temperatures detected in liquid methane used in the lander’s propulsion system. SpaceX said the issue was later resolved.

Although considered an Intuitive Machines mission, the IM-1 flight is carrying six NASA payloads of instruments designed to gather data about the lunar environment ahead of NASA’s planned return of astronauts to the moon later this decade.

Thursday’s launch came a month after the lunar lander of another private firm, Astrobotic Technology, suffered a propulsion system leak on its way to the moon shortly after being placed in orbit on January 8 by a United Launch Alliance (ULA) Vulcan rocket making its debut flight.

The failure of Astrobotic’s Peregrine lander, which was also flying NASA payloads to the moon, marked the third time a private company had been unable to achieve a “soft landing” on the lunar surface, following ill-fated efforts by companies from Israel and Japan.

Those mishaps illustrated the risks NASA faces in leaning more heavily on the commercial sector than it had in the past to realize its spaceflight goals.

Plans call for Intuitive Machines’ Nova-C vehicle, a hexagonal cylinder with four legs, to reach its destination after about a weeklong flight on February 22 for a landing at crater Malapert A near the moon’s south pole.

If successful, the flight would represent the first controlled descent to the lunar surface by a U.S. spacecraft since the final Apollo crewed moon mission in 1972, and the first by a private company.

The feat also would mark the first journey to the lunar surface under NASA’s Artemis moon program, as the U.S. races to return astronauts to Earth’s natural satellite before China lands its own crewed spacecraft there.

IM-1 is the latest test of NASA’s strategy of paying for the use of spacecraft built and owned by private companies to slash the cost of the Artemis missions, envisioned as precursors to human exploration of Mars.

By contrast, during the Apollo era, NASA bought rockets and other technology from the private sector, but owned and operated them itself.

NASA announced last month that it was delaying its target date for a first crewed Artemis moon landing from 2025 to late 2026, while China has said it was aiming for 2030.

Small landers such as Nova-C are expected to get there first, carrying instruments to closely survey the lunar landscape, its resources and potential hazards. Odysseus will focus on space weather interactions with the moon’s surface, radio astronomy, precision landing technologies and navigation.

Intuitive Machine’s IM-2 mission is scheduled to land at the lunar south pole in 2024, followed by an IM-3 mission later in the year with several small rovers.

Last month, Japan became the fifth country to place a lander on the moon, with its space agency JAXA achieving an unusually precise “pinpoint” touchdown of its SLIM probe last month. Last year, India became the fourth nation to land on the moon, after Russia failed in an attempt the same month.

The United States, the former Soviet Union and China are the only other countries that have carried out successful soft lunar touchdowns. China scored a world first in 2019 by achieving the first landing on the far side of the moon.
