Argentina says it will withdraw from WHO, echoing Trump

BUENOS AIRES — President Javier Milei has ordered Argentina’s withdrawal from the World Health Organization due to profound differences with the U.N. agency, a presidential spokesperson said Wednesday.

Milei’s action echoes that of his ally, U.S. President Donald Trump, who began the process of pulling the United States out of the WHO with an executive order on his first day back in office on Jan. 21.

Argentina’s decision is based on “profound differences in health management, especially during the [COVID19] pandemic,” spokesperson Manuel Adorni said at a news conference in Buenos Aires. He said that WHO guidelines at the time had led to the largest shutdown “in the history of mankind.”

He also said that the WHO lacked independence because of the political influence of some countries, without elaborating which countries.

Argentina will not allow an international organization to intervene in its sovereignty “and much less in our health,” Adorni said.

The WHO is the United Nations’ specialized health agency and is the only organization mandated to coordinate global responses to acute health crises, particularly outbreaks of new diseases and persistent threats such as Ebola, AIDS and mpox.

Former Google engineer faces new US charges he stole AI secrets for Chinese companies

U.S. prosecutors on Tuesday unveiled an expanded 14-count indictment accusing former Google software engineer Linwei Ding of stealing artificial intelligence trade secrets to benefit two Chinese companies he was secretly working for. 

Ding, 38, a Chinese national, was charged by a federal grand jury in San Francisco with seven counts each of economic espionage and theft of trade secrets. 

Each economic espionage charge carries a maximum 15-year prison term and $5 million fine, while each trade secrets charge carries a maximum 10-year term and $250,000 fine. 

The defendant, also known as Leon Ding, was indicted last March on four counts of theft of trade secrets. He is free on bond. His lawyers did not immediately respond to requests for comment. 

Ding’s case was coordinated through an interagency Disruptive Technology Strike Force created in 2023 by the Biden administration. 

The initiative was designed to help stop advanced technology from being acquired by countries such as China and Russia or potentially threatening national security. 

Prosecutors said Ding stole information about the hardware infrastructure and software platform that lets Google’s supercomputing data centers train large AI models. 

Some of the allegedly stolen chip blueprints were meant to give Google an edge over cloud computing rivals Amazon and Microsoft, which design their own, and reduce Google’s reliance on chips from Nvidia. 

Prosecutors said Ding joined Google in May 2019 and began his thefts three years later when he was being courted to join an early-stage Chinese technology company. 

Ding allegedly uploaded more than 1,000 confidential files by May 2023 and later circulated a PowerPoint presentation to employees of a China startup he founded, saying that country’s policies encouraged development of a domestic AI industry. 

Google was not charged and has said it cooperated with law enforcement. 

According to court records describing a December 18 hearing, prosecutors and defense lawyers discussed a “potential resolution” to Ding’s case, “but anticipate the matter proceeding to trial.” 

The case is U.S. v. Ding, U.S. District Court, Northern District of California, No. 24-cr-00141.

Scientists test injecting radioactivity into rhino horns to deter poachers

Scientists are testing a novel technique to deter poachers targeting endangered rhinoceroses for their prized horns. As part of a pilot study in South Africa, researchers have injected small, radioactive pellets into the horns of live rhinos. The goal is to make the horns radioactive so there is less demand for them on the black market. Marize de Klerk reports from the UNESCO Waterberg Biosphere Reserve.

Nigeria announces measures to soften impact of USAID programs’ suspension

Abuja, Nigeria — Nigerian officials have launched a committee to develop a transition and sustainability plan for USAID-funded health programs following U.S. President Donald Trump’s 90-day halt of most foreign aid. The multi-ministerial committee aims to secure new financial support for critical health programs. 

Nigeria’s health minister said the committee—comprising officials from the ministries of finance, health, and environment—intends to ensure that patients receiving treatment for HIV, tuberculosis, and malaria do not experience setbacks amid the uncertainty over U.S. foreign policy.

Shortly after taking office two weeks ago, U.S. President Donald Trump ordered a 90-day pause on U.S. foreign aid. But days later, he approved a temporary waiver for life-saving humanitarian assistance, covering medicine, medical services, food, and shelter.

Despite the exemption, concerns remain over the future of U.S. funding for global health programs.

Public health expert Ejike Orji welcomed Nigeria’s proactive response to the U.S. funding freeze.

“What this means is that they’re going to do a review, situation assessment of what’s going on and that would give them the opportunity to make recommendations to the government. They (U.S.) gave a ninety-day review because of the strategic importance of continuing the HIV program in Nigeria, so that means there’s still a possibility after their review, they might say, ‘Look, we don’t want to continue this funding,” said Orji.

Nigeria is a significant recipient of U.S. foreign aid, receiving $1.02 billion in 2023, much of it through agencies like USAID.

USAID funding to Nigeria plays a pivotal role in HIV/AIDS treatment, maternal and child care, and disease prevention efforts.

On Monday, the Nigerian Federal Executive Council approved $1 billion for healthcare sector reforms and allocated an additional $3.2 million to procure 150,000 HIV treatment packs over the next four months.

Authorities said the new funding will support improvements in primary healthcare services, maternal and child healthcare, and training of healthcare professionals.

But Ndeayo Iwot, general secretary of the Health Sector Reforms Coalition, said it will be difficult to sustain those programs without continued U.S. support.

“Even when they’re releasing the available funds on time, they will not be able to cover all the areas that those funds [aid] were helping them to achieve. It will take time, probably two, three years,” said Iwot.

Approximately 1.8 million Nigerians are living with HIV. The country also accounts for the world’s highest number of malaria deaths and ranks among the top countries for tuberculosis cases.

Iwot said Nigeria needs new partnerships for health programs.

“Health needs a multi sectoral approach, it works on partnerships, there are certain things you shouldn’t do alone as a country. Going through resource pulling from many partners and stakeholders is a recommended approach to financing health activities,” said Iwot.

Currently, only about 4% of Nigeria’s annual budget is allocated to the health sector—far below the 15 percent target set by African leaders in the 2001 Abuja Declaration.

It’s unclear whether the U.S. will reverse its decision after the 90-day pause. But with uncertainty looming, analysts say careful implementation of policies and new partnerships may be Nigeria’s best path forward.

Senate committee advances Robert F. Kennedy Jr. nomination to be health secretary

Washington — Robert F. Kennedy Jr., the controversial environmental lawyer turned public health critic, cleared his first hurdle on Tuesday to become the nation’s top health official when the senate finance committee voted to advance his nomination for a floor vote. 

Republicans voted together to advance his nomination, while Democrats all opposed. 

His nomination now will face a full senate vote, despite concerns about the work he’s done to sow doubts around vaccine safety and his potential to profit off lawsuits over drugmakers. 

To gain control of the $1.7 trillion Health and Human Services agency, Kennedy will need support from all but three Republicans if Democrats uniformly oppose him. 

Republican Sen. Bill Cassidy of Louisiana, who is also a physician and sits on the finance committee, voted to advance Kennedy’s confirmation. Last week, during Kennedy’s hearings, Cassidy repeatedly implored Kennedy to reject a disproven theory that vaccines cause autism, to no avail. He ended the hearing by saying he was “struggling” with the vote. 

“Your past, undermining confidence in vaccines with unfounded or misleading arguments, concerns me,” Cassidy told Kennedy. 

Republican Sens. Susan Collins of Maine, Lisa Murkowski of Alaska and Mitch McConnell of Kentucky are all seen as potential no votes, too, because they voted against President Donald Trump’s defense secretary nominee and have expressed concerns about Kennedy’s anti-vaccine work. 

In a CBS “60 Minutes” interview that aired Sunday, McConnell declined to say how he would vote on Kennedy’s nomination but reiterated “vaccines are critically important.” 

Democrats, meanwhile, continue to raise alarms about Kennedy’s potential to financially benefit from changing vaccine guidelines or weakening federal lawsuit protections against vaccine makers if confirmed as health secretary. 

“It seems possible that many different types of vaccine-related decisions and communications — which you would be empowered to make and influence as Secretary — could result in significant financial compensation for your family,” Democratic Sens. Elizabeth Warren of Massachusetts and Ron Wyden of Oregon wrote in a letter sent over the weekend to Kennedy. 

Kennedy said he’ll give his son all of the referral fees in legal cases against vaccine makers, including the fees he gets from referring clients in a case against Merck. Kennedy told the committee he’s referred hundreds of clients to a law firm that’s suing Merck’s Gardasil, the human papillomavirus vaccine that prevents cervical cancer. He’s earned $2.5 million from the deal over the past three years. 

As secretary, Kennedy will oversee vaccine recommendations and public health campaigns for the $1.7 trillion agency, which is also responsible for food and hospital inspections, providing health insurance for millions of Americans and researching deadly diseases. 

Kennedy, a longtime Democrat, ran for president but withdrew last year to throw his support to Trump in exchange for an influential job in his Republican administration. Together, they have forged a new and unusual coalition made up of conservatives who oppose vaccines and liberals who want to see the government promote healthier foods. Trump and Kennedy have branded the movement as “Make America Healthy Again.”

France pitches AI summit as ‘wake-up call’ for Europe

PARIS — France hosts top tech players next week at an artificial intelligence summit meant as a “wake-up call” for Europe as it struggles with AI challenges from the United States and China.

Players from across the sector and representatives from 80 nations will gather in the French capital on February 10 and 11 in the sumptuous Grand Palais, built for the 1900 Universal Exhibition.

In the run-up, President Emmanuel Macron will on Feb. 4 visit research centers applying AI to science and health, before hosting scientists and Nobel Prize winners at his Elysee Palace residence on Wednesday.

A wider science conference will be held at the Polytechnique engineering school on Thursday and Friday.

“The summit comes at exactly the right time for this wake-up call for France and Europe, and to show we are in position” to take advantage of the technology, an official in Macron’s office told reporters.

In recent weeks, Washington’s announcement of $500 billion in investment to build up AI infrastructure and the release of a frugal but powerful generative AI model by Chinese firm DeepSeek have focused minds in Europe.

France must “not let this revolution pass it by,” Macron’s office said.

Attendees at the summit will include Sam Altman, head of OpenAI — the firm that brought generative models to public consciousness in 2022 with the launch of ChatGPT.

Google boss Sundar Pichai and Nobel Prize winner Demis Hassabis, who leads the company’s DeepMind AI research unit, will also come, alongside Arthur Mensch, founder of French AI developer Mistral.

The Elysee has said there are “talks” on hosting DeepSeek founder Liang Wenfeng, and has yet to clarify whether X owner Elon Musk — who has his own generative initiative, xAI — has accepted an invitation.

Nor is it clear who will attend from the United States and China, with the French presidency saying only “very high level” representatives will come.

Confirmed guests from Europe include European Commission chief Ursula von der Leyen and German Chancellor Olaf Scholz.

‘Stoke confidence’

The tone of the AI summit will be “neither catastrophizing, nor naive,” Macron’s AI envoy Anne Bouverot told AFP.

Hosting the conference is also an opportunity for Paris to show off its own AI ecosystem, which numbers around 750 companies.

Macron’s office has said the summit would see the announcement of “massive” investments along the lines of his annual “Choose France” business conference, at which $15.4 billion of inward investment were pledged in 2024.

Beyond the economic opportunities, AI’s impact on culture including artistic creativity and news production will be discussed in a side-event over the weekend.

Debates open to the public, such as that one, are aimed at showing off “positive use cases for AI” to “stoke confidence and speed up adoption” of the technology, said France’s digital minister Clara Chappaz.

For now, the French public is skeptical of AI, with 79 percent of respondents telling pollsters Ifop they were “concerned” about the technology in a recent survey.

More ‘inclusive’ AI?

Paris says it also hopes the summit can help kick off its vision of a more ethical and accessible and less resource-intensive AI.

At present, “the AI under development is pushed by a few large players from a few countries,” Bouverot said, whereas France wants “to promote more inclusive development.”

Indian Prime Minister Narendra Modi has been invited to co-host the Paris summit, in a push to bring governments on board.

One of the summit’s aims is the establishment of a public-interest foundation for which Paris aims to raise $2.5 billion over five years.

The effort would be “a public-private partnership between various governments, businesses and philanthropic foundations from different countries,” Macron’s office said.

Paris hopes at the summit to chart different efforts at AI governance around the world and gather commitments for environmentally sustainable AI — although no binding mechanism is planned for now.

“There are lots of big principles emerging around responsible, trustworthy AI, but it’s not clear or easy to implement for the engineers in technical terms,” said Laure de Roucy-Rochegonde, director of the geopolitical technology center at the French Institute for International Relations.

Uganda begins Ebola vaccine trial

Uganda began a vaccine trial Monday against the Sudan strain of Ebola that has killed one person in the outbreak declared last week.

World Health Organization Director-General Tedros Adhanom Ghebreyesus said Monday in a post on the X social media platform that the trial was “initiated with record speed, only three days since the outbreak was declared, while ensuring full compliance with international and national regulatory and ethical requirements.”

Officials have not identified the vaccine manufacturer that is providing the East African country with access to more than 2,000 doses of the candidate vaccine.

WHO is supporting Uganda’s response to the outbreak with a $1 million allocation from its Contingency Fund for Emergencies.

So far, there has been only one death attributed to the virus — a nurse who worked at the Mulago National Referral Hospital in Kampala, Uganda’s capital. Two more cases were confirmed on Monday. The Associated Press reported they were members of the nurse’s family.

The nurse sought treatment at several hospitals and had also consulted with a traditional healer before tests confirmed an Ebola diagnosis, according to authorities.

Dr. Matshidiso Moeti, WHO regional director for Africa said in a statement after the outbreak was confirmed, “We welcome the prompt declaration of this outbreak, and as a comprehensive response is being established, we are supporting the government and partners to scale up measures to quicky identify cases, isolate and provide care, curb the spread of the virus and protect the population.”

Uganda’s Health Ministry has identified at least 234 of the nurse’s contacts, according to the AP. Containing the virus could prove challenging in Kampala with its population of 4 million people.

The symptoms of Ebola, an often-fatal disease, include fever, vomiting, diarrhea, muscle pain and at times internal and external bleeding.

According to the U.S. Centers for Disease Control and Prevention, health care workers and family members caring for someone with Ebola are at high risk for contracting the disease.

WHO said Ebola “is transmitted to people from wild animals (such as fruit bats, porcupines and non-human primates) and then spreads in the human population through direct contact with the blood, secretions, organs or other bodily fluids of infected people, and with surfaces and materials (e.g., bedding, clothing) contaminated with these fluids.”

Ebola’s fatality rate is around 50%, WHO said on its website, but it also said that fatality rates have varied from 25% to 90% in some outbreaks.

The outbreak in Uganda is the first Ebola outbreak since U.S. President Donald Trump announced the U.S. withdrawal from the World Health Organization.

Some information was provided by The Associated Press and Agence France-Presse.

Gerber recalls baby teething sticks over possible choking hazard

Arlington, Virginia — A baby food maker is recalling edible sticks meant to ease teething pain over a possible choking hazard. 

Gerber announced Friday that it was recalling and discontinuing its brand of “Sooth N Chew” teething sticks after receiving customer complaints about choking. The company said one emergency room visit had been reported. 

The teething sticks are edible teethers marketed to parents and guardians of children six months and older. They come in strawberry-apple and banana flavors. 

Gerber said it was working with the U.S. Food and Drug Administration on the recall. 

Customers who bought the teething sticks should return them to stores where they were purchased for a refund, the company said. 

Anyone concerned about an injury or illness should contact a health care provider. For any additional support needed, Gerber is available 24/7 at 1-800-4-GERBER (1-800-443-7237). 

The company says it is working with the U.S. FDA on this recall and will cooperate with them fully.

Uganda set to begin Ebola vaccine trial after new outbreak kills nurse

Kampala, Uganda — Ugandan officials are preparing to deploy a trial vaccine as part of efforts to stem an outbreak of Ebola in the capital, Kampala, a top health official said Sunday.

A range of scientists are developing research protocols relating to the planned deployment of more than 2,000 doses of a candidate vaccine against the Sudan strain of Ebola, said Pontiano Kaleebu, executive director of Uganda Virus Research Institute.

“Protocol is being accelerated” to get all the necessary regulatory approvals, he said. “This vaccine is not yet licensed.”

The World Health Organization said in a statement that its support to Uganda’s response to the outbreak includes access to 2,160 doses of trial vaccine.

“Research teams have been deployed to the field to work along with the surveillance teams as approvals are awaited,” the WHO statement said.

The candidate vaccine as well as candidate treatments are being made available through clinical trial protocols to further test for efficacy and safety, it said.

The vaccine maker wasn’t immediately known. There are no approved vaccines for the Sudan strain of Ebola that killed a nurse employed at Kampala’s main referral hospital. The man died on Wednesday and authorities declared an outbreak the next day.

 Officials are still investigating the source of the outbreak, and there has been no other confirmed case.

Uganda has had access to candidate vaccine doses since the end of an Ebola outbreak in September 2022 that killed at least 55 people. Ugandan officials ran out of time to begin a vaccine study when that outbreak, in central Uganda, was declared over about four months later, Kaleebu said.

A trial vaccine known as rVSV-ZEBOV, used to vaccinate 3,000 people at risk of infection during an outbreak of the Zaire strain of Ebola in eastern Congo between 2018 and 2020, proved effective in containing the spread of the disease there.

Uganda has had multiple Ebola outbreaks, including one in 2000 that killed hundreds. The 2014-16 Ebola outbreak in West Africa killed more than 11,000 people, the disease’s largest death toll.

Tracing contacts is also key to stemming the spread of Ebola, which manifests as a viral hemorrhagic fever.

At least 44 contacts of the victim in the current outbreak have been identified, including 30 health workers and patients, according to Uganda’s Ministry of Health.

Confirmation of Ebola in Uganda is the latest in a series of outbreaks of viral hemorrhagic fevers in the east African region. Tanzania declared an outbreak of the Ebola-like Marburg disease earlier this month, while in December Rwanda announced that its own outbreak of Marburg was over. The ongoing Marburg outbreak in northern Tanzania’s Kagera region has killed at least two people, according to local health authorities.

Kampala’s outbreak could prove difficult to respond to, because the city has a highly mobile population of about 4 million. The nurse who died had sought treatment at a hospital just outside Kampala and later traveled to Mbale, in the country’s east, where he was admitted to a public hospital. Health authorities said the man also sought the services of a traditional healer.

Ebola is spread by contact with bodily fluids of an infected person or contaminated materials. Symptoms include fever, vomiting, diarrhea, muscle pain and at times internal and external bleeding.

Scientists don’t know the natural reservoir of Ebola, but they suspect the first person infected in an outbreak acquired the virus through contact with an infected animal or eating its raw meat.

Ebola was discovered in 1976 in two simultaneous outbreaks in South Sudan and Congo, where it occurred in a village near the Ebola River, after which the disease is named.

Japan launches navigation satellite on new flagship rocket  

TOKYO — Japan’s space agency said Sunday it successfully launched a navigation satellite on its new flagship H3 rocket as the country seeks to have a more precise location positioning system of its own. 

The H3 rocket carrying the Michibiki 6 satellite lifted off from the Tanegashima Space Center on a southwestern Japanese island. 

Everything went smoothly and the satellite successfully separated from the rocket as planned about 29 minutes after the liftoff, said Makoto Arita, H3 project manager for the Japan Aerospace Exploration Agency, or JAXA. 

Officials said it is expected to reach its targeted geospatial orbit in about two weeks. 

Japan currently has the quasi-zenith satellite system, or QZSS, with four satellites for a regional navigation system that first went into operation in 2018. The Michibiki 6 will be the fifth of its network. 

Michibiki’s signals are used to supplement American GPS and will further improve positioning data for smartphones, car and maritime navigation and drones. 

Japan plans to launch two more navigation satellites to have a seven-satellite system by March 2026 to have a more precise global positioning capability without relying on foreign services, including the U.S., according to the Japan Science and Technology Agency. By the late 2030s, Japan plans to have an 11-satellite network. 

Sunday’s launch, delayed by a day due to the weather, was the fourth consecutive successful flight for the H3 system after a shocking failed debut attempt last year when the rocket had to be destroyed with its payload. 

Japan sees a stable, commercially competitive space transport capability as key to its space program and national security and has been developing two new flagship rockets as successors to the mainstay H2A series — the larger H3 and a much smaller Epsilon system. It hopes to cater to diverse customer needs and improve its position in the growing satellite launch market.

UK to become 1st country to criminalize AI child abuse tools

LONDON — Britain will become the first country to introduce laws against AI tools used to generate sexual abuse images, the government announced Saturday.

The government will make it illegal to possess, create or distribute AI tools designed to generate sexualized images of children, punishable by up to five years in prison, interior minister Yvette Cooper revealed.

It will also be illegal to possess AI “pedophile manuals” which teach people how to use AI to sexually abuse children, punishable by up to three years in prison.

“We know that sick predators’ activities online often lead to them carrying out the most horrific abuse in person,” said Cooper.

The new laws are “designed to keep our children safe online as technologies evolve. It is vital that we tackle child sexual abuse online as well as offline,” she added.

“Children will be protected from the growing threat of predators generating AI images and from online sexual abuse as the U.K. becomes the first country in the world to create new AI sexual abuse offences,” said a government statement.

AI tools are being used to generate child sexual abuse images by “nudeifying” real life images of children or by “stitching the faces of other children onto existing images,” said the government.

The new laws will also criminalize “predators who run websites designed for other pedophiles to share vile child sexual abuse content or advice on how to groom children,” punishable by up to ten years in prison, said the government.

The measures will be introduced as part of the Crime and Policing Bill when it comes to parliament.

The Internet Watch Foundation (IWF) has warned of the growing number of sexual abuse AI images of children being produced.

Over a 30-day period in 2024, IWF analysts identified 3,512 AI child abuse images on a single dark web site.

The number of the most serious category of images also rose by 10% in a year, it found.

US says life-saving HIV treatment can continue during aid pause

WASHINGTON — The U.S. State Department said Saturday that the President’s Emergency Plan for AIDS Relief (PEPFAR) — the world’s leading HIV initiative — was covered by a waiver for life-saving humanitarian assistance during a 90-day pause in foreign aid.

Just hours after taking office on Jan. 20, President Donald Trump ordered the pause so foreign aid contributions could be reviewed to see if they align with his “America First” foreign policy. The U.S. is the world’s largest aid donor.

Secretary of State Marco Rubio initially issued a waiver for emergency food aid and then Tuesday for life-saving medicine, medical services, food, shelter and subsistence help. However, the lack of detail in Trump’s order and the ensuing waivers has left aid groups confused as to whether their work can continue.

So, Saturday the State Department’s Bureau of Global Health Security and Diplomacy issued a memo, seen by Reuters, clarifying that PEPFAR was covered by the Jan. 28 memo and spelling out what activities were allowed.

These include life-saving HIV care and treatment services, including testing and counseling, prevention and treatment of infections including tuberculosis (TB), laboratory services, and procurement and supply chain for commodities/medicines. It also allows prevention of mother-to-child transmission services.

“Any other activities not specifically mentioned in this guidance may not be resumed without express approval,” it said.

More than 20 million people living with HIV, who represent two-thirds of all people living with the disease receiving treatment globally, are directly supported by PEPFAR.

Under Trump’s foreign aid pause, all payments by U.S. Agency for International Development (USAID) stopped Tuesday — for the first time since the fiscal year began on Oct. 1 — and have not resumed, according to U.S. Treasury data. On Monday USAID paid out $8 million and last week a total of $545 million.

The Trump administration is also moving to strip a slimmed-down USAID of its independence and put it under State Department control, two sources familiar with the discussions said Friday, in what would be a significant overhaul of how Washington allocates U.S. foreign aid.

Mushers, dogs braved Alaska winter to deliver lifesaving serum 100 years ago

ANCHORAGE, ALASKA — The Alaska Gold Rush town of Nome faced a bleak winter. It was hundreds of miles from anywhere, cut off by the frozen sea and unrelenting blizzards, and under siege from a contagious disease known as the “strangling angel” for the way it suffocated children. 

Now, 100 years later, Nome is remembering its saviors — the sled dogs and mushers who raced for more than five days through hypothermia, frostbite, gale-force winds and blinding whiteouts to deliver lifesaving serum and free the community from the grip of diphtheria. 

Among the events celebrating the centennial of the 1925 “Great Race of Mercy” are lectures, a dog-food drive and a reenactment of the final leg of the relay, all organized by the Nome Kennel Club. 

Alaskans honor ‘heroic effort’ 

“There’s a lot of fluff around celebrations like this, but we wanted to remember the mushers and their dogs who have been at the center of this heroic effort and … spotlight mushing as a still-viable thing for the state of Alaska,” said Diana Haecker, a kennel club board member and co-owner of Alaska’s oldest newspaper, The Nome Nugget. 

“People just dropped whatever they were doing,” she said. “These mushers got their teams ready and went, even though it was really cold and challenging conditions on the trail.” 

Other communities are also marking the anniversary — including the village of Nenana, where the relay began, and Cleveland, Ohio, where the serum run’s most famous participant, a husky mix named Balto, is stuffed and displayed at a museum. 

Jonathan Hayes, a Maine resident who has been working to preserve the genetic line of sled dogs driven on the run by famed musher Leonhard Seppala, is recreating the trip. Hayes left Nenana on Monday with 16 Seppala Siberian sled dogs, registered descendants of Seppala’s team. 

A race to save lives

Diphtheria is an airborne disease that causes a thick, suffocating film on the back of the throat; it was once a leading cause of death for children. The antitoxin used to treat it was developed in 1890, and a vaccine in 1923; it is now exceedingly rare in the U.S. 

Nome, western Alaska’s largest community, had about 1,400 residents a century ago. Its most recent supply ship had arrived the previous fall, before the Bering Sea froze, without any doses of the antitoxin. Those the local doctor, Curtis Welch, had were outdated, but he wasn’t worried. He hadn’t seen a case of diphtheria in the 18 years he had practiced in the area. 

Within months, that changed. In a telegram, Welch pleaded with the U.S. Public Health Service to send serum: “An epidemic of diphtheria is almost inevitable here.” 

The first death was a 3-year-old boy on January 20, 1925, followed the next day by a 7-year-old girl. By the end of the month, there were more than 20 confirmed cases. The city was placed under quarantine. 

West Coast hospitals had antitoxin doses, but it would take time to get them to Seattle, Washington, and then onto a ship for Seward, Alaska, an ice-free port south of Anchorage, Alaska. In the meantime, enough for 30 people was found at an Anchorage hospital. 

It still had to get to Nome. Airplanes with open-air cockpits were ruled out as unsuited for the weather. There were no roads or trains that reached Nome. 

Instead, officials shipped the serum by rail to Nenana in interior Alaska, some 1,086 kilometers (675 miles) from Nome via the frozen Yukon River and mail trails. 

Thanks to Alaska’s new telegraph lines and the spread of radio, the nation followed along, captivated, as 20 mushers — many of them Alaska Natives — with more than 150 dogs relayed the serum to Nome. They battled deep snow, whiteouts so severe they couldn’t see the dogs in front of them, and life-threatening temperatures that plunged at times to minus minus 51 degrees Celsius (60 degrees Fahrenheit).

The antitoxin was transported in glass vials covered with padded quilts. Not a single vial broke. 

Seppala, a Norwegian settler, left from Nome to meet the supply near the halfway point and begin the journey back. His team, led by his dog Togo, traveled more than 320 kilometers (250 miles) of the relay, including a treacherous stretch across frozen Norton Sound. 

After about 5 1/2 days, the serum reached its destination on February 2, 1925. A banner front-page headline in the San Francisco Chronicle proclaimed “Dogs victors over blizzard in battle to succor stricken Nome.” 

The official record listed five deaths and 29 illnesses. It’s likely the toll was higher; Alaska Natives were not accurately tracked. 

Balto gains fame 

Seppala and Togo missed the limelight that went to his assistant, Gunnar Kaasen, who drove the dog team led by Balto into Nome. Balto was another of Seppala’s dogs, but was used to only haul freight after he was deemed too slow to be on a competitive team.

Balto was immortalized in movies and with statues in New York’s Central Park and one in Anchorage intended as a tribute to all sled dogs. He received a bone-shaped key to the city of Los Angeles, where legendary movie actress Mary Pickford placed a wreath around his neck. 

But he and several team members were eventually sold and kept in squalid conditions at a dime museum in Los Angeles. After learning of their plight, an Ohio businessman spearheaded an effort to raise money to bring them to Cleveland, a city in Ohio. After dying in 1933, Balto was mounted and placed on display at the Cleveland Museum of Natural History. 

Iditarod pays homage to run 

Today, the most famous mushing event in the world is the Iditarod Trail Sled Dog Race, which is not based on the serum run but on the Iditarod Trail, a supply route from Seward to Nome. Iditarod organizers are nevertheless marking the serum run’s centennial with a series of articles on its website and by selling replicas of the medallions each serum run musher received a century ago, race spokesperson Shannon Noonan said in an email. This year’s Iditarod starts March 1. 

“The Serum Run demonstrated the critical role sled dogs played in the survival and communication of remote Alaskan communities, while the Iditarod has evolved into a celebration of that tradition and Alaska’s pioneering spirit,” Noonan said.

RFK Jr. vows to stop collecting from vaccine lawsuit if confirmed to Cabinet

WASHINGTON — Facing intense scrutiny from U.S. senators over his potential profit from vaccine lawsuits while serving as the nation’s health secretary, Robert F. Kennedy Jr. said that if he is confirmed he will not collect fees from litigation against the drugmakers of a cervical cancer vaccine.

Kennedy, who’s President Donald Trump’s pick to lead the U.S. Health and Human Services agency, told the Senate finance committee that he would amend his ethics disclosure after several senators, including Democrat Elizabeth Warren of Massachusetts, and his cousin Caroline Kennedy raised concerns about his financial arrangement with the law firm representing patients who are claiming injuries from the vaccines.

“An amendment to my Ethics Agreement is in process, and it provides that I will divest my interest in this litigation,” Kennedy said in a written response to the committee.

Initially, Kennedy had told the committee that he would continue to accept referral fees in legal cases that don’t involve the U.S. government. That included an arrangement with a law firm that’s sued Merck over Gardasil, its human papillomavirus vaccine that prevents cervical cancer. The deal earned Kennedy $850,000 last year, and he told senators he had referred hundreds of clients to the firm.

During Wednesday’s hearing, Warren outlined several ways in which Kennedy could make it easier to sue vaccine manufacturers.

“Kennedy can kill off access to vaccines and make millions of dollars while he does it,” Warren said. “Kids might die, but Robert Kennedy can keep cashing in.”

The issue also may have been a concern for Senator Bill Cassidy, a Louisiana Republican who is also a physician and is conflicted over his vote on Kennedy’s confirmation because of Kennedy’s anti-vaccine views.

The Republican president’s nominee is “financially vested in finding fault with vaccines,” Cassidy, the chair of the health committee, noted as he ended Thursday’s confirmation hearing.

Kennedy also stopped short of making other commitments, refusing to promise that he would not engage in lobbying Health and Human Services after his term ends.

Kennedy and his supporters have railed against that sort of activity, saying the “revolving door” of Washington — where federal officials trade public service jobs to influence government agencies while in the private sector — has undermined the U.S. public health system. He has criticized the practice at least a half-dozen times in social media posts over recent years.

Kennedy, who ran for president last year before dropping his bid and endorsing Trump, vowed in one post on social media platform X to “rein in lobbyists and slam shut the revolving door,” if elected president.

He first challenged President Joe Biden for the 2024 Democratic presidential nomination but then ran as an independent before striking a deal to endorse Trump in exchange for a promise to serve in a health policy role during a second Trump administration.

Now, after two days of hearings, his shot at that job is on the line with concerns about his anti-vaccine advocacy prompting nearly all Democrats to reject his nomination and a handful of Republicans who are at least considering doing the same.

If Democrats unanimously oppose Kennedy, he’ll need support from all but three Republicans. The Senate finance committee is expected to decide if he makes it to the Senate floor for a vote next week.

Kennedy’s response to the Senate committee was first reported by The New York Times.

Uganda health officials warn of Ebola outbreak

KAMPALA, UGANDA — A day after Uganda’s Ministry of Health announced a new Ebola outbreak in the capital, Kampala, most Ugandans appeared unaware or unconcerned about the outbreak and went about their business normally. But health authorities are warning Ugandans not to take Ebola lightly.

For weeks, Uganda has battled an outbreak of mpox, also known as monkeypox, that has affected more than 2,000 people and caused 13 deaths, according to the World Health Organization.

But Dr. Julius Lutwama, deputy director of the Uganda Virus Research Institute, said Ugandans need to worry more about Ebola than mpox.

“Ebola is more highly infectious even than monkeypox,” Lutwama said. “And it is even a more severe infection than monkeypox. The percentage of people that end up dead from Ebola is up to 80% while for monkeypox it is below 5%.”

Ebola killed more than 50 people in Uganda during the 2022 outbreak.

Nurse dies of Ebola

On Thursday, Dr. Diana Atwine, Uganda’s permanent secretary in the Ministry of Health, announced the new outbreak after a 32-year-old nurse died from the disease.

Atwine said the nurse sought treatment at multiple health facilities including Mulago National Referral Hospital and from a traditional healer. The patient suffered with high fever, chest pain and difficulty breathing since Jan. 20, then unexplained bleeding and multiple organ failure before dying Wednesday.

Atwine said the nurse died from the Sudan strain of Ebola.

‘We will leave it to God’

While the Ministry of Health is cautioning the public with reminders of the symptoms of Ebola, several Kampala residents who spoke to VOA said they had not heard about or were not worried about the outbreak.

Kampala resident Ntale Steven said he is not going to shut down his business.

“We will leave it to God, so the disease doesn’t spread,” he said. “And if there’s an outbreak, we should get treatment and be helped. Health workers should also care for whoever gets infected. Because we have nothing to do, we must move.”

Health authorities have moved to quarantine those who had contact with the deceased Ebola victim. Out of the 44 people in isolation, 30 are health workers from the National Referral Hospital. The rest are family members and health workers from other private facilities.

Lutwama said because it takes days before symptoms start to show, this is when most infected persons transmit the disease to others, placing health workers at a higher risk.

“Many people then can transmit it during that period, before they come to that stage of bleeding,” said Lutwama. “But still the health workers are supposed to be on the lookout. And they are also supposed to be protected, but as you know, sometimes our hospitals are missing a few things like gloves, they don’t have hypochlorite like Jik [bleach] to be able to wash their hands thoroughly and things like that.”

Even with warnings from Lutwama and the Ministry of Health, Ogwang John, a security guard, said he will take precautions only if he gets an order from his boss.

“Me, I’m not worried,” he said. “I always go with the decision of my boss. When he says that we do this, the disease is there, yes, we can take. But if he has not talked with me, I’m also a carefree man.”

The Ministry of Health said it will continue tracing contacts and monitoring those under isolation as they await more support from the World Health Organization’s contingency fund for emergencies.

DeepSeek vs. ChatGPT fuels debate over AI building blocks

SEOUL, SOUTH KOREA — When Chinese startup DeepSeek released its AI model this month, it was hailed as a breakthrough, a sign that China’s artificial intelligence companies could compete with their Silicon Valley counterparts using fewer resources.

The narrative was clear: DeepSeek had done more with less, finding clever workarounds to U.S. chip restrictions. However, that storyline has begun to shift.

OpenAI, the U.S.-based company behind ChatGPT, now claims DeepSeek may have improperly used its proprietary data to train its model, raising questions about whether DeepSeek’s success was truly an engineering marvel.

In statements to several media outlets this week, OpenAI said it is reviewing indications that DeepSeek may have trained its AI by mimicking responses from OpenAI’s models.

The process, known as distillation, is common among AI developers but is prohibited by OpenAI’s terms of service, which forbid using its model outputs to train competing systems.

Some U.S. officials appear to support OpenAI’s concerns. At his confirmation hearing this week, Commerce secretary nominee Howard Lutnick accused DeepSeek of misusing U.S. technology to create a “dirt cheap” AI model.

“They stole things. They broke in. They’ve taken our IP,” Lutnick said of China.

David Sacks, the White House czar for AI and cryptocurrency, was more measured, saying only that it is “possible” that DeepSeek had stolen U.S. intellectual property.

In an interview with the cable news network Fox News, Sacks added that there is “substantial evidence” that DeepSeek “distilled the knowledge out of OpenAI’s models,” adding that stronger efforts are needed to curb the rise of “copycat” AI systems.

At the center of the dispute is a key question about AI’s future: how much control should companies have over their own AI models, when those programs were themselves built using data taken from others?

AI data fight

The question is especially relevant for OpenAI, which faces its own legal challenges. The company has been sued by several media companies and authors who accuse it of illegally using copyrighted material to train its AI models.

Justin Hughes, a Loyola Law School professor specializing in intellectual property, AI, and data rights, said OpenAI’s accusations against DeepSeek are “deeply ironic,” given the company’s own legal troubles.

“OpenAI has had no problem taking everyone else’s content and claiming it’s ‘fair,'” Hughes told VOA in an email.

“If the reports are accurate that OpenAI violated other platforms’ terms of service to get the training data it has wanted, that would just add an extra layer of irony – dare we say hypocrisy – to OpenAI complaining about DeepSeek.”

DeepSeek has not responded to OpenAI’s accusations. In a technical paper released with its new chatbot, DeepSeek acknowledged that some of its models were trained alongside other open-source models – such as Qwen, developed by China’s Alibaba, and Llama, released by Meta – according to Johnny Zou, a Hong Kong-based AI investment specialist.

However, OpenAI appears to be alleging that DeepSeek improperly used its closed-source models – which cannot be freely accessed or used to train other AI systems.

“It’s quite a serious statement,” said Zou, who noted that OpenAI has not yet presented evidence of wrongdoing by DeepSeek.

Proving improper distillation may be difficult without disclosing details on how its own models were trained, Zou added.

Even if OpenAI presents concrete proof, its legal options may be limited. Although Zou noted that the company could pursue a case against DeepSeek for violating its terms of service, not all experts believe such a claim would hold up in court.

“Even assuming DeepSeek trained on OpenAI’s data, I don’t think OpenAI has much of a case,” said Mark Lemley, a professor at Stanford Law School who specializes in intellectual property and technology.

Even though AI models often have restrictive terms of service, “no model creator has actually tried to enforce these terms with monetary penalties or injunctive relief,” Lemley wrote in a recent paper with co-author Peter Henderson.

The paper argues that these restrictions may be unenforceable, since the materials they aim to protect are “largely not copyrightable.”

“There are compelling reasons for many of these provisions to be unenforceable: they chill good faith research, constrain competition, and create quasi-copyright ownership where none should exist,” the paper noted.

OpenAI’s main legal argument would likely be breach of contract, said Hughes. Even if that were the case, though, he added, “good luck enforcing that against a Chinese company without meaningful assets in the United States.”

Possible options

The financial stakes are adding urgency to the debate. U.S. tech stocks dipped Monday after following news of DeepSeek’s advances, though they later regained some ground.

Commerce nominee Lutnick suggested that further government action, including tariffs, could be used to deter China from copying advanced AI models.

But speaking the same day, U.S. President Donald Trump appeared to take a different view, surprising some industry insiders with an optimistic take on DeepSeek’s breakthrough.

The Chinese company’s low-cost model, Trump said, was “very much a positive development” for AI, because “instead of spending billions and billions, you’ll spend less, and you’ll come up with hopefully the same solution.”

If DeepSeek has succeeded in building a relatively cheap and competitive AI model, that may be bad for those with investment – or stock options – in current generative AI companies, Hughes said.

“But it might be good for the rest of us,” he added, noting that until recently it appeared that only the existing tech giants “had the resources to play in the generative AI sandbox.”

“If DeepSeek disproved that, we should hope that what can be done by a team of engineers in China can be done by a similarly resourced team of engineers in Detroit or Denver or Boston,” he said.
