Montgomery, Alabama — The Alabama Supreme Court has ruled that frozen embryos can be considered children under state law, a ruling critics said could have sweeping implications for fertility treatments. 

The decision was issued in a pair of wrongful death cases brought by three couples who had frozen embryos destroyed in an accident at a fertility clinic. Justices, citing anti-abortion language in the Alabama Constitution, ruled that an 1872 state law allowing parents to sue over the death of a minor child “applies to all unborn children, regardless of their location.” 

“Unborn children are ‘children’ … without exception based on developmental stage, physical location, or any other ancillary characteristics,” Justice Jay Mitchell wrote in the majority ruling Friday from the all-Republican court. 

Mitchell said the court had previously ruled that fetuses killed while a woman is pregnant are covered under Alabama’s Wrongful Death of a Minor Act and nothing excludes “extrauterine children from the Act’s coverage.” 

The ruling brought a rush of warnings about the potential impact on fertility treatments and the freezing of embryos, which had previously been considered property by the courts. 

“This ruling is stating that a fertilized egg, which is a clump of cells, is now a person. It really puts into question the practice of IVF,” Barbara Collura, CEO of RESOLVE: The National Infertility Association, said in an interview Tuesday. The group called the decision a “terrifying development for the 1 in 6 people impacted by infertility” who need in-vitro fertilization. 

She said it raises questions for providers and patients, including if they can freeze future embryos created during fertility treatment or if patients could ever donate or destroy unused embryos. 

The plaintiffs in the Alabama case had undergone IVF treatments that led to the creation of several embryos, some of which were implanted and resulted in healthy births. The couples had paid to keep others frozen in a storage facility at the Mobile Infirmary Medical Center. A patient in 2020 wandered into the area and removed several embryos, dropping them on the floor and “killing them,” the ruling said. 

The justices ruled that wrongful death lawsuits by the couples could proceed. 

An anti-abortion group cheered the decision. “Each person, from the tiniest embryo to an elder nearing the end of his life, has incalculable value that deserves and is guaranteed legal protection,” Lila Rose, president and founder of Live Action said in a statement. 

Chief Justice Tom Parker issued a concurring opinion that quoted the Bible as he discussed the meaning of the phrase “the sanctity of unborn life” in the Alabama Constitution. 

“Even before birth, all human beings bear the image of God, and their lives cannot be destroyed without effacing his glory,” Parker said. 

Justice Greg Cook, who filed the only full dissent to the majority opinion, said the 1872 law did not define “minor child” and was being stretched from the original intent to cover frozen embryos. 

“Moreover, there are other significant reasons to be concerned about the main opinion’s holding. No court — anywhere in the country — has reached the conclusion the main opinion reaches,” he wrote, adding the ruling “almost certainly ends the creation of frozen embryos through in vitro fertilization (IVF) in Alabama.” 

The Alabama Supreme Court decision partly hinged on anti-abortion language added to the Alabama Constitution in 2018, stating that it is the “public policy of this state to ensure the protection of the rights of the unborn child.” 

Supporters at the time said it would “be a declaration of voters’ beliefs” and would have no impact unless states gain more control over abortion access. States gained control of abortion access in 2022. Critics at the time said it would have broad ramifications for civil and criminal law beyond abortion access and that it was essentially a “personhood” measure that would establish constitutional rights for fertilized eggs.

CAPE CANAVERAL, FLORIDA — Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. 

The record-breaking quasar shines 500 trillion times brighter than our sun. The black hole powering this distant quasar is more than 17 billion times more immense than our sun, an Australian-led team reported Monday in the journal Nature Astronomy. 

While the quasar resembles a mere dot in images, scientists envision a ferocious place. 

The rotating disk around the quasar’s black hole — the luminous swirling gas and other matter from gobbled-up stars — is like a cosmic hurricane. 

“This quasar is the most violent place that we know in the universe,” lead author Christian Wolf of Australian National University said in an email. 

The European Southern Observatory spotted the object, J0529-4351, during a 1980 sky survey, but it was thought to be a star. It was not identified as a quasar — the extremely active and luminous core of a galaxy — until last year. Observations by telescopes in Australia and Chile’s Atacama Desert clinched it. 

“The exciting thing about this quasar is that it was hiding in plain sight and was misclassified as a star previously,” Yale University’s Priyamvada Natarajan, who was not involved in the study, said in an email. 

These later observations and computer modeling have determined that the quasar is gobbling up the equivalent of 370 suns a year — roughly one a day. Further analysis shows the mass of the black hole to be 17 to 19 billion times that of our sun, according to the team. More observations are needed to understand its growth rate. 

The quasar is 12 billion light-years away and has been around since the early days of the universe. A light-year is 5.8 trillion miles.

LONDON — Lockbit, a notorious cybercrime gang that holds its victims’ data for ransom, has been disrupted in a rare international law enforcement operation by Britain’s National Crime Agency, the U.S. Federal Bureau of Investigation, Europol and a coalition of international police agencies, according to a post on the gang’s extortion website on Monday.

“This site is now under the control of the National Crime Agency of the UK, working in close cooperation with the FBI and the international law enforcement task force, ‘Operation Cronos,’” the post said.

An NCA spokesperson confirmed that the agency had disrupted the gang and said the operation was “ongoing and developing.”

A representative for Lockbit did not respond to messages from Reuters seeking comment but did post messages on an encrypted messaging app saying it had backup servers not affected by the law enforcement action.

The U.S. Department of Justice and the FBI did not immediately respond to requests for comment.

The post named other international police organizations from France, Japan, Switzerland, Canada, Australia, Sweden, the Netherlands, Finland and Germany.

Lockbit and its affiliates have hacked some of the world’s largest organizations in recent months. The gang makes money by stealing sensitive data and threatening to leak it if victims fail to pay an extortionate ransom. Its affiliates are like-minded criminal groups that are recruited by the group to wage attacks using Lockbit’s digital extortion tools.

Ransomware is malicious software that encrypts data. Lockbit makes money by coercing its targets into paying ransom to decrypt or unlock that data with a digital key.

Lockbit was discovered in 2020 when its eponymous malicious software was found on Russian-language cybercrime forums, leading some security analysts to believe the gang is based in Russia.

The gang has not professed support for any government, however, and no government has formally attributed it to a nation-state. On its now-defunct dark web site, the group said it was “located in the Netherlands, completely apolitical and only interested in money.”

“They are the Walmart of ransomware groups, they run it like a business — that’s what makes them different,” said Jon DiMaggio, chief security strategist at Analyst1, a U.S.-based cybersecurity firm. “They are arguably the biggest ransomware crew today.”

Officials in the United States, where Lockbit has hit more than 1,700 organizations in nearly every industry from financial services and food to schools, transportation and government departments, have described the group as the world’s top ransomware threat.

In November of last year, Lockbit published internal data from Boeing, one of the world’s largest defense and space contractors. In early 2023, Britain’s Royal Mail faced severe disruption after an attack by the group.

According to vx-underground, a cybersecurity research website, Lockbit said in a statement in Russian and shared on Tox, an encrypted messaging app, that the FBI hit its servers that run on the programming language PHP. The statement, which Reuters could not verify independently, added that it has backup servers without PHP that “are not touched.”

On X, formerly known as Twitter, vx-underground shared screenshots showing the control panel used by Lockbit’s affiliates to launch attacks had been replaced with a message from law enforcement: “We have source code, details of the victims you have attacked, the amount of money extorted, the data stolen, chats, and much, much more,” it said.

“We may be in touch with you very soon” it added. “Have a nice day.”

Before it was taken down, Lockbit’s website displayed an ever-growing gallery of victim organizations that was updated nearly daily. Next to their names were digital clocks that showed the number of days left to the deadline given to each organization to provide ransom payment.

On Monday, Lockbit’s site displayed a similar countdown, but from the law enforcement agencies who hacked the hackers: “Return here for more information at: 11:30 GMT on Tuesday 20th Feb.” the post said.

Don Smith, vice president of Secureworks, an arm of Dell Technologies, said Lockbit was the most prolific and dominant ransomware operator in a highly competitive underground market.

“To put today’s takedown into context, based on leak site data, Lockbit had a 25% share of the ransomware market. Their nearest rival was Blackcat at around 8.5%, and after that it really starts to fragment,” Smith said.

“Lockbit dwarfed all other groups and today’s action is highly significant.”

WASHINGTON — U.S. lawmakers are raising alarms about what they see as America’s failure to compete with China in biotechnology, warning of the risks to U.S. national security and commercial interests. But as the two countries’ rivalry expands into the biotech industry, some say that shutting out Chinese companies would only hurt the U.S.

Biotechnology promises to revolutionize everyday life, with scientists and researchers using it to make rapid advances in medical treatment, genetic engineering in agriculture and novel biomaterials. Because of its potential, it has caught the attention of both the Chinese and U.S. governments.

Bills have been introduced in the House and Senate to bar “foreign adversary biotech companies of concern” from doing business with federally funded medical providers. The bills name four Chinese-owned companies.

The Chinese Embassy said those behind the bills have an “ideological bias” and seek to suppress Chinese companies “under false pretexts.” It demanded that Chinese companies be given “open, just, and non-discriminatory treatment.”

The debate over biotechnology is taking place as the Biden administration tries to stabilize the volatile U.S.-China relationship, which has been battered by a range of issues, including a trade war, the COVID-19 pandemic, cybersecurity and militarization in the South China Sea.

Critics of the legislation warn that restrictions on Chinese companies would impede advances that could bring a greater good.

“In biotech, one cannot maintain competitiveness by walling off others,” said Abigail Coplin, an assistant professor at Vassar College who specializes in China’s biotech industry. She said she was worried that U.S. policymakers would get too obsessed with the technology’s military applications at the cost of hindering efforts to cure disease and feed the world’s population.

In a letter to senators sponsoring the bill, Rachel King, chief executive officer of the trade association Biotechnology Innovation Organization, said the legislation would “do untold damage to the drug development supply chain both for treatments currently approved and on market as well as for development pipelines decades in the making.”

But supporters say the legislation is crucial to protecting U.S. interests.

The National Security Commission on Emerging Biotechnology, a group created by the U.S. Senate to review the industry, said the bill would help secure the data of the federal government and of American citizens and it would discourage unfair competition from Chinese companies.

The commission warned that advancement in biotechnology can result not only in economic benefits but also rapid changes in military capabilities.

Much is at stake, said Rep. Mike Gallagher, chair of the House Select Committee on the Chinese Communist Party. Gallagher introduced the House version of the bill and last week led a congressional delegation to Boston to meet with biotech executives.

“It’s not just a supply chain battle or a national security battle or an economic security battle; I would submit it’s a moral and ethical battle,” Gallagher said. “Just as the sector advances at a really astronomic pace, the country who wins the race will set the ethical standards around how these technologies are used.”

He argues that the U.S. must “set the rules of the road” and if not, “we’re going to live in a less free, less moral world as a result.”

Both the United States and China, the world’s two largest economies, have identified biotech as a critical national interest.

The Biden administration has put forward a “whole-of-government approach” to advance biotechnology and biomanufacturing that is important for health, climate change, energy, food security, agriculture and supply chain resilience.

The Chinese government has plans to develop a “national strategic technology force” in biotech, which would be tasked with making breakthroughs and helping China achieve “technological independence,” primarily from the U.S.

“Both the Chinese government and the Americans have identified biotech as an area important for investment, a sector that presents an opportunity to grow their economy,” said Tom Bollyky, the Bloomberg chair in global health at the Council on Foreign Relations. He said any restrictive U.S. measures should be tailored to address military concerns and concerns about genomic data security.

“Naturally there’s going to be competition, but what’s challenging in biotech is that we are talking about human health,” Bollyky said.

Ray Yip, who founded the U.S. Centers for Disease Control and Prevention office in China, also worries that the rivalry will slow medical advancements.

The benefit of coming up with better diagnostics and therapy is beyond any individual country, Yip said, “and will not overshadow the capacity or prestige of the other country.”

What concerns Anna Puglisi, a senior fellow at Georgetown University’s Center for Security and Emerging Technology, is Beijing’s lack of transparency and its unfair market practices. “Competition is one thing. Unfair competition is another thing,” she said.

Puglisi described BGI, a major Chinese biotech company identified in both the House and Senate bills, as “a national champion” that is subsidized and given favored treatment by the state in a system that “blurs private and public as well as civilian and military.”

“This system creates market distortions and undermines the global norms of science by using researchers and academic and commercial entities to further the goals of the state,” Puglisi said.

BGI, which has stressed its private ownership, offers genetic testing kits and a popular prenatal screening test to detect Down syndrome and other conditions. U.S. lawmakers say they are concerned such data could end up in the hands of the Chinese government.

The Defense Department has listed BGI as a Chinese military company, and the Commerce Department has blacklisted it on human rights grounds, citing a risk that BGI technology might have contributed to surveillance. BGI has rejected the allegations.

In raising its concerns about BGI, the National Security Commission on Emerging Biotechnology says the company is required to share data with the Chinese government, has partnered with the Chinese military, and has received considerable Chinese state funding and support.

State subsidies have allowed BGI to offer genomic sequencing services at a highly competitive price that is attractive to U.S. researchers, according to the commission. The genomic data, once in the hands of the Chinese government, “represents a strategic asset that has privacy, security, economic, and ethical implications,” it said.

BGI could not immediately be reached for comment.

paris — A new artificial intelligence tool that promises to create short videos from simple text commands has raised concerns along with questions from artists and media professionals. 

OpenAI, the creator of ChatGPT and image generator DALL-E, said Thursday it was testing a text-to-video model called “Sora” that can allow users to create realistic videos with simple prompts. 

The San Francisco-based startup says Sora can “generate complex scenes with multiple characters, specific types of motion, and accurate details of the subject and background,” but admits it still has limitations, such as possibly “mixing up left and right.” 

Here are early reactions from industries that could be affected by the new generative artificial intelligence (AI) tool:   

Examples of Sora-created clips on OpenAI’s website range widely in style and subject, from seemingly real drone footage above a crowded market to an animated bunny-like creature bouncing through a forest. 

Thomas Bellenger, founder and art director of Cutback Productions, has been carefully watching the evolution of generative AI image generation.   

“There were those who felt that it was an unstoppable groundswell that was progressing at an astonishing rate, and those who just didn’t want to see it,” said Bellenger, whose France-based company has created large scale visual effects for such touring musicians as Stromae and Justice. 

He said the development of generative AI has “created a lot of debate internally” at the company and “a lot of sometimes visceral reactions.” 

Bellenger noted that Sora has yet to be released, so its capabilities have yet to be tested by the public. 

“What is certain is that no one expected such a technological leap forward in just a few weeks,” Bellenger said. “It’s unheard of.” 

He said whatever the future holds, they’ll “find ways to create differently.” 

Mixed reaction among creators

Video game creators are equally likely to be impacted by the new invention, with reaction among the sector divided between those open to embracing a new tool and those fearing it might replace them. 

French video game giant Ubisoft hailed the OpenAI announcement as a “quantum leap forward” with the potential to let players and development teams express their imaginations. 

“We’ve been exploring this potential for a long time,” a Ubisoft spokesperson told AFP. 

Alain Puget, chief of Nantes-based studio Alkemi, said he won’t replace any artists with AI tools, which “only reproduce things done by humans.” 

Nevertheless, Puget noted, this “visually impressive” tool could be used by small studios to produce more professionally rendered images. 

While video “cut scenes” that play out occasionally to advance game storylines are different from player-controlled action, Puget expects tools like Sora to eventually be able to replace “the way we do things.”   

‘A terrifying leap’

Basile Simon, a former journalist and current Stanford University researcher, thinks there has been “a terrifying leap forward in the last year” when it comes to generative AI allowing realistic-looking fabrications to be rapidly produced. 

He dreads the idea of how such tools will be abused during elections and fears the public will “no longer know what to believe”. 

Julien Pain of French TV channel France Info’s fact-checking program “Vrai ou Faux” (True or False) says he’s also worried about abuse of AI tools. 

“Until now, it was easy enough to spot fake images, for example by noticing the repetitive faces in the background,” Pain said. “What this new software does seems to be on another level.” 

While OpenAI and U.S. tech titans may promote safety tools, such as industry-wide watermarks that reveal AI-created imagery, “what about tomorrow’s competitors in China and Russia?” he posited. 

The Fred & Farid agency, which has collaborated with the Longchamp and Budweiser brands and where a studio dedicated to AI was opened in early January, anticipates that “80 percent of brand content will be generated by artificial intelligence.” 

“Creative genius” will no longer be limited by production skills thanks to generative AI tools, one enthusiast contended.   

Stephanie Laporte, chief executive and founder of the OTTA advertising and influencer agency, believes the technology will “force the industry to evolve.” 

She also anticipates ad companies with lean budgets will resort to AI tools to save money on workers. 

A possible exception, she believes, is the luxury segment, where brands are “very sensitive to authenticity” and “will probably use AI sparingly.”

TOKYO — Japan’s flagship H3 rocket reached orbit and released two small observation satellites in a key second test following a failed debut launch last year, buoying hope for the country in the global space race.

The H3 rocket blasted off from the Tanegashima Space Center on time Saturday morning, two days after its originally scheduled liftoff was delayed by bad weather.

The rocket successfully reached orbit at an altitude of about 670 kilometers (about 420 miles) and released two satellites, said the Japan Aerospace Exploration Agency, or JAXA.

“We feel so relieved to be able to announce the good results,” JAXA President Hiroshi Yamakawa told a news conference.

The H3’s main missions are to secure independent access to space and be competitive as international demand for satellite launches grows. “We made a big first step today toward achieving that goal,” Yamakawa said.

The launch is a boost for Japan’s space program following a recent streak of successes, including a historic precision touchdown on the moon of an unmanned spacecraft last month.

The liftoff was closely watched as a test for Japan’s space development after H3, in its debut flight last March, failed to ignite the second-stage engine. JAXA and its main contractor, Mitsubishi Heavy Industries, have been developing H3 as a successor to its current mainstay, H-2A, which is set to retire after two more flights.

JAXA H3 project manager Masashi Okada called the result “perfect,” saying H3 cleared all missions set for Saturday’s flight. “After a long wait, the newborn H3 finally had its first cry.”

At 57 meters (187 feet) long, the H3 is designed to carry larger payloads than H-2A at much lower costs of about 50 billion yen ($330 million).

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.

SINGAPORE — Singapore will play host to Asia’s biggest air show next week for the first time since the end of COVID border restrictions, with regional travel rebounding and the military side of the show bristling with defensive systems and nervous arms buyers.

An expected full return of civil demand in Asia is being tested by an industry-wide supply crunch and macroeconomic headwinds, however — especially in the world’s second-largest aviation market, China — while geopolitical tensions have put weapons in the spotlight.

“Supply chain issues are limiting the ability of many airlines to upgrade their fleets and service their aircraft,” said Association of Asia Pacific Airlines head Subhas Menon.

The biennial show will feature the first trip outside Chinese territory for China’s first homegrown passenger jet, COMAC’s narrow-body C919.

With the dominant two plane manufacturers, Airbus and Boeing, struggling to ramp up production and meet demand for new planes, and Boeing struggling with a string of crises, air show attendees will be watching how the Commercial Aircraft Corporation of China, or COMAC, positions itself as a viable alternative.

Many inside the industry caution that only four C919s are in service in China; the plane is only certified by Chinese regulators; and the C919 relies on international supply chains.

Nevertheless, China’s aviation authority has said it would promote the plane internationally this year and pursue European Union Aviation Safety Agency certification.

“We have also seen a growing trend where clients are including the C919 option in their fleet evaluation,” said Adam Cowburn of Alton Aviation Consultancy.

COMAC will be one of two commercial plane makers flying their planes alongside Airbus. Boeing will not send a commercial aircraft to the show this year.

It is the first major international industry event since last month’s blowout of a door plug on a 737 MAX 9 pushed Boeing into its second safety crisis in five years and sent images of a fuselage with a gaping hole whizzing across the globe.

Analyst Sash Tusa of U.K.-based Agency Partners said that in the past, the industry rarely discussed aviation safety in public, on the assumption that any mention would undermine confidence.

“But this omerta no longer seems to apply,” he added in a note.

Environmental impact

Singapore will invite industry delegates to discuss aviation’s environmental impact and will reveal a plan for making Singapore’s aviation sector sustainable. In November, the global aviation industry agreed to lower fuel carbon emissions 5% by 2030, toward a goal of “net zero” carbon emissions by 2050.

“For the industry to meet its Fly Net Zero ambitions by 2050, Asia will be a key driver given that it will continue to remain the largest aviation market,” Cowburn said.

A massive ramp-up in sustainable aviation fuel, or SAF, production is the current hope for meeting these targets, but it costs three to five times more than traditional jet fuel and there are concerns about how to sustainably meet demand.

“That awareness of aviation’s climate impact has been rising, and the questions about this industry’s license to operate have been increasingly raised — without there being a credible path of tackling that problem,” said Sami Jauhiainen of refiner Neste, which started refining SAF in Singapore last year.

Defense needs

Some new freighters are also in demand, delegates said. Amid spiraling tensions over Taiwan, disputes over South China Sea sovereignty and a spike in North Korean missile tests, regional defense budgets are rising. Systems from small drones to complex sub-hunting aircraft will be on display.

The war in Ukraine, which has seen extensive use of high-end air defenses, and repeated attacks on Red Sea shipping, may also spur interest in systems that can intercept missiles and drones, as well as intelligence, surveillance and reconnaissance platforms used to keep tabs on adversaries. No Russian companies are listed among the exhibitors at the air show.

Six air forces will stage flying demonstrations, including the United States and India.

Washington — The U.S. Justice Department said on Thursday it disrupted a Russian intelligence hacking network.

“For the second time in two months, we’ve disrupted state-sponsored hackers from launching cyber-attacks behind the cover of compromised U.S. routers,” U.S. Deputy Attorney General Lisa Monaco said in a statement.

The Justice Department said that a January 2024 court-authorized operation neutralized the network of hundreds of small office/home office (SOHO) routers controlled by Russian intelligence and used “to conceal and otherwise enable a variety of crimes.”  

“In this case, Russian intelligence services turned to criminal groups to help them target home and office routers, but the Justice Department disabled their scheme,” Attorney General Merrick Garland added.

Garland said the Justice Department was accelerating efforts to disrupt the Russian government’s cyber campaigns against the United States and its partners, including Ukraine.

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%.”
