new york — Your wallet may soon be getting thinner.

Visa on Wednesday announced major changes to how credit and debit cards will operate in the U.S. in the coming months and years.

The new features could mean Americans will be carrying fewer physical cards in their wallets, and will make the 16-digit credit or debit card number printed on every card increasingly irrelevant.

They will be some of the biggest changes to how payments operate in the U.S. since the U.S. rolled out chip-embedded cards several years ago. They also come as Americans have many more options to pay for purchases beyond “credit or debit,” including buy now, pay later companies, peer-to-peer payment options, paying directly with a bank, or digital payment systems such as Apple Pay.

“I think (with these features) we’re getting past the point where consumers may never need to manually enter an account number ever again,” said Mark Nelsen, Visa’s global head of consumer payments.

The biggest change coming for Americans will be the ability for banks to issue one physical payment card that will be connected to multiple bank accounts. That means no more carrying, for example, a Bank of America or Chase debit card as well as their respective credit cards in a physical wallet. Americans will be able to set criteria with their bank — such as having all purchases below $100 or with a certain merchant applied to the debit card, while other purchases go on the credit card.

The feature, already being used in Asia, will be available this summer. Buy now, pay later company Affirm is the first of Visa’s customers to roll out the feature in the U.S.

Fraud prompts changes

Some of Visa’s new features are in response to online-payments fraud, which continues to increase as more countries adopt digital payments. The company based in San Francisco, California, estimates that payment fraud happens roughly seven times more often online than it does in person, and there are now billions of stolen credit and debit card numbers available to criminals.

Other new elements are also in response to features that non-payments companies have rolled out in recent years. The Apple Card, which uses Mastercard as its payment network, does not come with a printed 16-digit account number and Apple Card users can request a fresh credit card number at any time without having to dispose of the physical card.

Visa executives see a future where banks will issue cards where the 16-digit account number, if the new cards come with them, is largely symbolic.

Soon, fingerprints can approve transactions

Among the other updates unveiled by Visa are changes to tap-to-pay features. Americans will be able to tap their credit or debit cards to their smartphones to add the card to mobile wallets, instead of using a smartphone’s camera to scan in a card’s information, or tap the card to their smartphones to approve a transaction online. Visa will also start implementing biometrics to approve transactions, similar to how Apple devices use a fingerprint or face scan to approve transactions.

The features will take time to filter down to the banks, which will decide when or what to implement for their customers. But because the banks and credit card companies are Visa’s customers, and issue cards with the Visa label, these are features that the financial institutions have been asking for.

LONDON — A scenic fishing village in southwestern England was under instructions to boil its tap water for a third day on Friday after a parasite sickened more than 45 people in the latest example of Britain’s troubled water system.

Around 16,000 homes and businesses in the Brixham area of Devon were told to boil water after cryptosporidium, a microscopic parasite that causes diarrhea, was found in the water. At least 46 cases of cryptosporidiosis have been confirmed and more than 100 other people have reported similar symptoms, the U.K. Health Security Agency said. Symptoms can last more than two weeks.

Sally Dart, who runs a housewares shop near Brixham Harbor, said people in town first began feeling ill two weeks ago during a pirate festival.

“No one was checking the quality of the water, and we’ve all got sick and it’s stupid,” she said. 

South West Water’s Chief Executive Susan Davy apologized for the outbreak and said technicians were working around the clock to identify and fix the problem that may have come from a pipe in a cattle pasture.

“I am truly sorry for the disruption and wider anxiety this has caused,” Davy said. “I know on this occasion we have fallen significantly short of what you expect of us.”

The crisis is unrelated to Britain’s larger ongoing water woes but emblematic of an aging system in distress.

Water companies have been under fire for more than a year to stop frequent sewage overflows into rivers and oceans that have literally caused a stink, sickened swimmers, polluted fishing streams and led to an outcry from the public to clean up their act.

An environmental group this week reported that 70,000 sewage releases spilled for a total of 400,000 hours along England’s coast last year. More than a quarter were within 3.2 kilometers of a swimming spot, Friends of the Earth said in its analysis of government data.

Clean water advocates have blamed the problems on Britain’s privatization of the water system in 1989. They say that companies have put shareholders ahead of customers and not spent enough to update outdated plumbing systems.

Thames Water, the largest of the companies, is on the brink of insolvency and its leaders have said it faces the risk of being nationalized after shareholders refused to inject more cash.

Earlier this week, in another sign of problems, millions of gallons of raw sewage were pumped into England’s largest lake. After a fault caused pumps to fail, backup systems then pumped human waste into Lake Windermere, a UNESCO World Heritage site, for 10 hours, the BBC reported.

The cryptosporidiosis outbreak is hardly the first time South West Water has encountered problems, according to authorities.

The company is facing charges in Plymouth Magistrates’ Court alleging 30 offenses for illegal water discharges or breaches of environmental permits between 2015 and 2021, the Environment Agency said.

The recent outbreak appears to come from a damaged air valve in a pipe that runs through a field where cows graze that is close to a reservoir, said Laura Flowerdew, a spokesperson for South West.

With word out about the outbreak, Dart said her business is down by about a third and other merchants complained about a loss of income as warmer weather arrives and a holiday weekend is just a week away.

“I would say it’s quiet and it shouldn’t be at this time of year,” Dart said.

A primary school was forced to close Thursday because it didn’t have clean drinking water. The water company is providing free bottled water at three locations and has increased compensation to customers from 15 pounds ($19) to 115 ($145).

Paul Hunter, a professor in medicine at the University of East Anglia, said it’s likely more people will become ill with cryptosporidiosis in coming days or weeks because of a lag in the incubation period.

“Even if they have stopped all new infections by now, you would expect to see further cases for at least 10 days to two weeks,” he told the BBC.

Anthony Mangnall, a Conservative member of Parliament from the area, said residents are likely to have to boil water for another week. He said he was concerned with the water company’s response to the outbreak and vowed to hold it accountable.

“They have been slow to act and communication with customers has been very poor,” Mangnall said. “This has certainly undermined trust in our water network.”

SYDNEY — Australian scientists say they have discovered how an enzyme “hidden in nature’s blueprint” could help develop climate-resilient crops able to remove more carbon dioxide from the atmosphere. 

An Australian study, by researchers from Australian National University and the University of Newcastle in New South Wales, focuses on a type of bacteria researchers call “tiny carbon superheroes.” 

Cyanobacteria, a type of algae-like bacteria also called blue-green algae, are found in fresh and coastal waters, as well as oceans.  They are commonly known for their toxic blooms in lakes and rivers.  

Through the process of photosynthesis, Australian scientists say, they capture about 12% of the world’s carbon dioxide each year. 

Their study says a carbon dioxide-concentrating mechanism in cyanobacteria lets them turn atmospheric carbon dioxide into sugars for cells to eat more quickly than most standard plants and crops.

Until now, the Australian team was unaware how critical an enzyme in cyanobacteria, called carboxysomal carbonic anhydrase, was to the process. The study says the mystery of how the enzyme maximizes the cyanobacteria’s ability to extract atmospheric carbon dioxide has been solved.

Ben Long, a senior lecturer in molecular plant biology at Australia’s University of Newcastle and is the study’s lead author.

He told VOA that the aim is to engineer crops that can absorb more greenhouse gases.   

“We are actually interested in utilizing this CO2-concentrating mechanism from cyanobacteria, which we know is a remarkably efficiently system for capturing CO2 and we want to engineer that into plant cells to make plant cells able to capture CO2 far more effectively and efficiently,” Long said.

The research says that engineered plants that are more efficient at capturing carbon dioxide could increase crop yield, making global food systems that are more resilient to climate change. 

Long says the findings should be part of international efforts to reduce greenhouse gases.  

“Every technology has to be brought to bear to try to reduce CO2 emissions and reduce CO2 in the atmosphere and I think to date we have not really focused much on those potential biological applications to reduce greenhouse gas emissions,” Long said.

The study has been published in the journal Science Advances.

Washington — Aleksander Dugin, a Russian nationalist ideologue and strong supporter of President Vladimir Putin, has been bombarded with attacks on Chinese social media, where netizens criticized and mocked his Russian expansionist views that had once included the dismembering of China.

Two years after Putin launched an invasion of Ukraine, pro-Russia sentiment has been prevalent on Chinese internet.

But the backlash against Dugin has revealed a less mentioned side of what has so far appeared to be a cozy alliance between Beijing and Moscow — hostility between Chinese nationalists and their Russian counterparts, the result of centuries of territorial disputes and political confrontations that Beijing has been reticent about displaying publicly in recent decades.

On May 6, Dugin opened an account on two of the most popular Chinese social media apps Weibo, China’s X, formerly known as Twitter, and Bilibili, a YouTube-like video site.

In the first video posted on both Weibo and Bilibili, Dugin greeted the Chinese audience and praised Beijing’s economic and political achievements in recent decades.

In the same video, he also criticized an article published in April in The Economist by Feng Yujun, director of Russian and Central Asian studies at Fudan University in Shanghai. Feng said in the article that Russia will inevitably lose the Ukraine war.

Dugin countered that Feng and some Chinese people underestimated Russia’s “tenacity and perseverance.”

The video was quickly condemned by Chinese citizens, who posted comments such as “Russia must lose,” which received thousands of likes.

“This is an extremist who is extremely unfriendly to China and has made plans to dismember China,” another message posted by a Weibo user named “Zhixingbenyiti” said.

Dugin, 62, was born in Moscow. In the 1980s, he became an anti-communist dissident.

After the collapse of the Soviet Union, he began to promote Russian expansionism. He believes that Moscow’s territorial expansion in Eurasia will allow it to counter Western forces led by the United States.

In his 1997 book, Foundations of Geopolitics, Dugin wrote that dismembering China was a necessary step for Russia to become strong. People within Putin’s inner circle have reportedly shown interest in Dugin’s writing, which gave rise to his nickname “Putin’s brain.”

However, Dugin’s attitude toward China has changed significantly in recent years. In 2018, he visited China for the first time. In a speech at Fudan University, he praised China’s economy, culture and leadership in the fight against colonialism.

He also changed his previous support for containing China and said in a speech that China and Russia could work together to “form a very important and non-negligible containment/pull effect” on Western powers.

Dugin is now a senior fellow at Fudan University’s China Institute and one of the columnists for China’s nationalist news organization, Guancha.

Before Russia invaded Ukraine in February 2022, Dugin said in a column that the alliance between China and Russia would “mean the irreversible end of Western hegemony.”

Philipp Ivanov, a senior fellow at the Asia Society Policy Institute, told VOA that “Dugin is an opportunist. As the Ukraine war dramatically accelerated the alignment between China and Russia, his position started to change, resulting in his current attempt to engage with China’s intellectual and broader community.”

Ivanov also thinks Dugin’s influence on the Kremlin has been exaggerated.

Since joining Chinese social media, Dugin has gained more than 100,000 followers on Weibo and 25,000 followers on BiliBili. He has published fewer than five posts on Weibo, but nearly every one of them has more than 1,000 comments, most of which criticized him.

Under a post in which Dugin supported Putin on his fifth presidential term, people responded with comments such as “Russia is about to lose the war” and “The gates of hell are waiting for you.”

Wang Xiaodong, China’s most influential nationalist scholar, shared a Weibo post he made two years ago criticizing Dugin and Chinese pro-Russian groups.

“Introducing Dugin’s ideas is not because I worry that the Kremlin will implement his ideas; He has the intention but not the strength! I just want to tell the Chinese people how some Russians, including elites in the powerful departments, view China. Do we Chinese need to risk our lives for them?” the post read.

Ivanov was not surprised by the attacks on Dugin on the Chinese internet.

“While Chinese netizens may support Putin’s anti-Western/anti-US agenda, they are skeptical or outright negative about Russia’s assault on an independent country’s sovereignty and Russian expansionism, nationalism and chauvinism (which Dugin represents),” he told VOA in an email.

He said the history of China-Russia relations is predominantly about confrontation, competition and mistrust.

Among the attacks on Dugin, many netizens also brought up former Chinese territories that Russia occupied in the past 200 years.

“For the sake of ever-lasting friendship between China and Russia, please return Sakhalin and Vladivostok,” one Weibo comment posted by “lovejxcecil” read.

Although China has not been involved in the war, the Russia-Ukraine war has been a hot topic on the Chinese internet.

According to Eric Liu, a former Weibo censor, Dugin’s joining the platform undoubtedly brought more traffic to Weibo. However, it also means that Weibo needs to invest more resources in censorship to prevent him from making remarks that Beijing considers sensitive.

“He is a foreigner. He has no idea about China’s ‘political correctness’ or where the boundaries are,” Liu said. “This risk will have to be taken care of by Weibo, which brought him in.”

On Thursday, Dugin posted on Weibo that China and Russia could achieve “anything” together. His comment section has been turned off.

WASHINGTON — U.S. prosecutors on Thursday announced the arrests of an American woman and a Ukrainian man they say helped North Korea-linked IT workers posing as Americans to obtain remote-work jobs at hundreds of U.S. companies.

The U.S. Department of Justice (DoJ) said the elaborate scheme, aimed at generating revenue for North Korea in contravention of international sanctions, involved the infiltration of more than 300 U.S. firms, including Fortune 500 companies and banks, and the theft of the identities of more than 60 Americans.

A DoJ statement said the overseas IT workers also attempted to gain employment and access to information at two U.S. government agencies, although these efforts were “generally unsuccessful.”

An earlier State Department statement said the scheme had generated at least $6.8 million for North Korea. It said the North Koreans involved were linked to North Korea’s Munitions Industry Department, which oversees development of the country’s ballistic missiles, weapons production, and research and development programs.

An indictment filed in federal court in Washington last week and unsealed on Thursday said charges had been filed against Christina Marie Chapman, 49, of Litchfield Park, Arizona; Ukrainian Oleksandr Didenko, 27, of Kyiv; and three other foreign nationals.

A Justice Department statement said Chapman was arrested on Wednesday, while Didenko was arrested on May 7 by Polish authorities at the request of the United States, which is seeking his extradition.

The State Department announced a reward of up to $5 million for information related to Chapman’s alleged co-conspirators, who used the aliases Jiho Han, Haoran Xu and Chunji Jin, and another unindicted individual using the aliases Zhonghua and Venechor S.

Court records did not list lawyers for those arrested and it was not immediately clear whether they had legal representation.

The head of the Justice Department’s Criminal Division, Nicole Argentieri, said the alleged crimes “benefited the North Korean government, giving it a revenue stream and, in some instances, proprietary information stolen by the co-conspirators.”

The charges “should be a wakeup call for American companies and government agencies that employ remote IT workers,” she said in the statement.

It said the scheme “defrauded U.S. companies across myriad industries, including multiple well-known Fortune 500 companies, U.S. banks, and other financial service providers.”

The DoJ said Didenko was accused of creating fake accounts at U.S. IT job search platforms, selling them to overseas IT workers, some of whom he believed were North Korean. It said overseas IT workers using Didenko’s services were also working with Chapman.

Didenko’s online domain, upworksell.com, was seized Thursday by the Justice Department, the statement said.

The DOJ statement said the FBI executed search warrants for U.S.-based “laptop farms” – residences that hosted multiple laptops for overseas IT workers.

It said that through these farms, including one Chapman hosted from her home, U.S.-based facilitators logged onto U.S. company computer networks and allowed the overseas IT workers to remotely access the laptops, using U.S. IP addresses to make it appear they were in the United States.

The statement said search warrants for four U.S. residences associated with laptop farms controlled by Didenko were issued in the Southern District of California, the Eastern District of Tennessee, and Eastern District of Virginia, and executed between May 8 and May 10.

North Korea is under U.N. sanctions aimed at cutting funding for its missile and nuclear weapons programs and experts say it has sought to generate income illicitly, including through IT workers.

Confidential research by a now-disbanded U.N. sanctions monitoring panel seen by Reuters on Tuesday showed they had been investigating 97 suspected North Korean cyberattacks on cryptocurrency companies between 2017 and 2024, valued at some $3.6 billion.

The U.N. sanctions monitors were disbanded at the end of April after Russia vetoed renewal of their mandate.

A research report from a Washington think tank in April said North Korean animators may have helped create popular television cartoons for big Western firms despite international sanctions.

CAPE CANAVERAL, FLORIDA — The Webb Space Telescope has discovered the earliest known merger of black holes.

These two gigantic black holes and their galaxies consolidated just 740 million years after the universe-forming Big Bang. It’s the most distant detection ever made of merging black holes, scientists reported Thursday.

One black hole is 50 million times more massive than our sun. The other is thought to be similar in size, but is buried in dense gas, which makes it harder to measure.

Until now, astronomers weren’t sure how supermassive black holes got so big.

The latest findings, published in the Monthly Notices of the Royal Astronomical Society, suggest mergers are how black holes can grow so rapidly — “even at cosmic dawn,” said lead author Hannah Ubler of the University of Cambridge.

“Massive black holes have been shaping the evolution of galaxies from the very beginning,” Ubler said in a statement.

Launched in 2021 as the eventual successor to NASA’s Hubble Space Telescope, Webb is the biggest and most powerful observatory ever sent into space. A joint U.S.-European project, the infrared observatory surveys the universe from a location 1.6 million kilometers from Earth.

TAIPAI, TAIWAN — Taiwanese chipmaker TSMC said Thursday there was no damage to its facilities after an incident at its Arizona factory construction site where

a waste disposal truck driver was transported to a hospital.

Firefighters responded to a reported explosion Wednesday afternoon at the Taiwan Semiconductor Manufacturing Company plant in Phoenix, the Arizona Republic reported, citing the local fire department.

TSMC, the world’s largest contract chipmaker whose clients include Apple and Nvidia, said in a statement none of its employees or onsite construction workers had reported any related injuries.

“This is an active investigation with no additional details that can be shared at this time,” it added.

TSMC’s Taipei-listed shares pared earlier gains after the news and were last up around 0.8% on Thursday morning. TSMC last month agreed to expand its planned investment by $25 billion to $65 billion and to add a third Arizona plant by 2030.

The company will produce the world’s most advanced 2 nanometer technology at its second Arizona facility expected to begin production in 2028.

NEW YORK — The number of fatal overdoses in the U.S. fell last year, according to Centers for Disease Control and Prevention data posted Wednesday.

Agency officials noted that the data is provisional and could change after more analysis, and that they still expect a drop when the final counts are in. It would be only the second annual decline since the current national drug death epidemic began more than three decades ago.

Experts reacted cautiously. One described the decline as relatively small and said it should be thought of as part of a leveling off rather than a decrease. Another noted that the last time a decline occurred — in 2018 — drug deaths shot up in the years that followed.

“Any decline is encouraging,” said Brandon Marshall, a Brown University researcher who studies overdose trends. “But I think it’s certainly premature to celebrate or to draw any large-scale conclusions about where we may be headed long term with this crisis.”

It’s also too soon to know what spurred the decline, Marshall and other experts said. Explanations could include shifts in the drug supply, expansion of overdose prevention and addiction treatment, and the grim possibility that the epidemic has killed so many that now there are basically fewer people to kill.

CDC Chief Medical Officer Dr. Debra Houry called the dip “heartening news” and praised efforts to reduce the tally, but she noted that “there are still families and friends losing their loved ones to drug overdoses at staggering numbers.”

About 107,500 people died of overdoses in the U.S. last year, including American citizens and noncitizens who were in the country at the time they died, the CDC estimated. That’s down 3% from 2022, when there were an estimated 111,000 such deaths, the agency said.

The drug overdose epidemic, which has killed more than 1 million people since 1999, has had many ripple effects. For example, a study published last week in JAMA Psychiatry estimated that more than 321,000 U.S. children lost a parent to a fatal drug overdose from 2011 to 2021.

“These children need support” and are at a higher risk of mental health and drug use disorders themselves, said Dr. Nora Volkow, director of the National Institute on Drug Abuse, which helped lead the study. “It’s not just a loss of a person. It’s also the implications that loss has for the family left behind.”

Prescription painkillers once drove the nation’s overdose epidemic, but they were supplanted years ago by heroin and more recently by illegal fentanyl. The dangerously powerful opioid was developed to treat intense pain from ailments such as cancer but has increasingly been mixed with other drugs in the illicit drug supply.

For years, fentanyl was frequently injected, but increasingly it’s being smoked or mixed into counterfeit pills.

A study published last week found that law enforcement seizures of pills containing fentanyl are rising dramatically, jumping from 44 million in 2022 to more than 115 million last year.

It’s possible that the seizures indicate that the overall supply of fentanyl-laced pills is growing fast, not necessarily that police are whittling down the illicit drug supply, said one of the paper’s authors, Dr. Daniel Ciccarone of the University of California, San Francisco.

He noted that the decline in overdoses was not uniform. All but two of the states in the eastern half of the U.S. saw declines, but most Western states saw increases. Alaska, Washington and Oregon each saw 27% increases.

The reason? Many Eastern states have been dealing with fentanyl for about a decade, while it’s reached Western states more recently, Ciccarone said.

Nevertheless, some researchers say there are reasons to be optimistic. It’s possible that smoking fentanyl is not as lethal as injecting it, but scientists are still exploring that question.

Meanwhile, more money is becoming available to treat addiction and prevent overdoses, through government funding and legal settlements with drugmakers, wholesalers and pharmacies, Ciccarone noted.

“My hope is 2023 is the beginning of a turning point,” he said.

SYDNEY — Researchers in New Zealand say that artificial intelligence, or AI, can help solve problems for patients and doctors.  

A new study from the University of Auckland says that an emerging area is the use of AI during operations using so-called “computer vision.”

The study, published in the journal Nature Medicine, says that artificial intelligence has the potential to identify abnormalities during operations and to unburden overloaded hospitals by enhancing the monitoring of patients to help them recover after surgery at home.

The New Zealand research details how AI “tools are rapidly maturing for medical applications.”  It asserts that “medicine is entering an exciting phase of digital innovation.”

The New Zealand team is investigating computer vision, which describes a machine’s understanding of videos and images. 

Dr. Chris Varghese, a doctoral researcher in the Department of Surgery at the Faculty of Medical and Health Sciences at the University of Auckland, led the AI research team.

He told VOA the technology has great potential.

“The use of AI in surgery is a really emerging field. We are seeing a lot of exciting research looking at what we call computer vision, where AI is trying to learn what surgeons see, what the surgical instruments look like, what the different organs look like, and the potential there is to identify abnormal anatomy or what the safest approach to an operation might be using virtual reality and augmented reality to plan ahead of surgeries, which could be really useful in cutting out cancers and things like that.”

Varghese said doctors in New Zealand are already using AI to help sort through patient backlogs.

“We are using automated algorithms to triage really long waiting lists,” he said. “So, getting people prioritized and into clinics ahead of time, based on need, so the right patients are seen at the right time.”

The researchers said there are limitations to the use of artificial intelligence because of concerns about data privacy and ethics.

The report concludes that “numerous apprehensions remain with regard to the integration of AI into surgical practice, with many clinicians perceiving limited scope in a field dominated by experiential” technology.

The study also says that “autonomous robotic surgeons…. is the most distant of the realizable goals of surgical AI systems.”
