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.

FDA approves painkiller designed to eliminate risk of addiction

WASHINGTON — Federal officials on Thursday approved a new type of pain pill designed to eliminate the risks of addiction and overdose associated with opioid medications like Vicodin and OxyContin.

The U.S. Food and Drug Administration said it approved Vertex Pharmaceuticals’ Journavx for short-term pain that often follows surgery or injuries.

It’s the first new pharmaceutical approach to treating pain in more than 20 years, offering an alternative to both opioids and over-the-counter medications like ibuprofen and acetaminophen. But the medication’s modest effectiveness and lengthy development process underscore the challenges of finding new ways to manage pain.

Studies in more than 870 patients with acute pain because of foot and abdominal surgeries showed Vertex’s drug provided more relief than a dummy pill but didn’t outperform a common opioid-acetaminophen combination pill.

“It’s not a slam dunk on effectiveness,” said Michael Schuh of the Mayo Clinic, a pharmacist and pain medicine expert who was not involved in the research. “But it is a slam dunk in that it’s a very different pathway and mechanism of action. So, I think that shows a lot of promise.”

The new drug will carry a list price of $15.50 per pill, making it many times more expensive than comparable opioids, which are often available as generics for $1 or less.

Vertex began researching the drug in the 2000s, when overdoses were rocketing upward, principally driven by mass prescribing of opioid painkillers for common ailments like arthritis and back pain. Prescriptions have fallen sharply in the last decade and the current wave of the opioid epidemic is mainly due to illicit fentanyl, not pharmaceutical medicines.

Opioids reduce pain by binding to receptors in the brain that receive nerve signals from different parts of the body. Those chemical interactions also give rise to opioids’ addictive effects.

Vertex’s drug works differently, blocking proteins that trigger pain signals that are later sent to the brain.

“In trying to develop medicines that don’t have the addictive risks of opioid medicines, a key factor is working to block pain signaling before it gets to the brain,” Vertex’s Dr. David Altshuler, told The Associated Press last year.

Commonly reported side effects with the drug were nausea, constipation, itching, rash and headache.

“The new medication has side effect profiles that are inherently, not only different, but don’t involve the risk of substance abuse and other key side effects associated with opioids,” said Dr. Charles Argoff of the Albany Medical Center, who consulted for Vertex on the drug’s development.

The initial concept to focus on pain-signaling proteins came out of research involving people with a rare hereditary condition that causes insensitivity to pain.

Ugandan nurse dies of Ebola

A male nurse in Uganda has died of Ebola, the first recorded death by the disease in the East African country since an outbreak ended in 2023, health officials said.

The 32-year-old nurse worked at Mulago National Specialised Hospital in Kampala, Diana Atwine, permanent secretary of Uganda’s health ministry, said Thursday.

The nurse died Wednesday of the Sudan strain of Ebola, Atwine said.

He sought treatment at several hospitals and had also consulted with a traditional healer before tests confirmed an Ebola diagnosis, health officials said.

World Health Organization Director-General Tedros Adhanom Ghebreyesus posted on X that his organization was supporting Uganda’s efforts to contain an Ebola outbreak in Uganda with a $1 million allocation from WHO’s Contingency Fund for Emergencies.

Atwine said on her X social media account that “rapid response teams are fully deployed, contact tracing is underway, and all necessary measures are in place to contain the situation. We assure the public that we are in full control.”

Contact tracing, however, could be challenging in Kampala, with its population of 4 million people.

The health ministry, however, reported that it had identified 44 contacts of the late nurse, which included 30 other health care workers.

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.

Republican senator airs concerns about supporting RFK Jr to be US health secretary

WASHINGTON — A key Republican senator on Thursday said he was struggling with Robert F. Kennedy Jr.’s nomination by President Donald Trump to run the top U.S. health agency, saying he had reservations about the nominee’s “misleading arguments” on vaccines.   

“Your past of undermining confidence in vaccines with unfounded or misleading arguments concerns me,” Republican Senator Bill Cassidy, a physician from Louisiana, told Kennedy. 

“I have been struggling with the nomination,” he said at the end of Thursday’s Senate health committee hearing to consider Kennedy to run the massive Department of Health and Human Services. 

“Does a 70-year-old man … who spent decades criticizing vaccines and who’s financially vested in finding fault with vaccines, can he change his attitudes and approach now that he’ll have the most important position influencing vaccine policy in the United States?” Cassidy said. 

The hearing was the second in two days for Kennedy during which he squared off with Democrats and some Republicans over his past comments on vaccines, abortion and COVID-19 among other topics. 

The Finance Committee, which Kennedy appeared before on Wednesday, has not yet said if it will send Kennedy’s nomination to the full Republican-controlled Senate, which has not rejected any of Trump’s nominees so far. 

A spokesperson for the Finance Committee said a vote could potentially take place next week, but that one had not yet been scheduled.   

Cassidy, who sits on both committees, told Kennedy at the end of Thursday’s hearing that Kennedy would be hearing from him over the weekend, presumably regarding questions he has over the nomination.   

Kennedy’s nomination could fail to move to the Senate for consideration if all Democrats on the Finance Committee voted against him and were joined by Cassidy.   

During wide-ranging questioning on Thursday, Kennedy spoke more confidently than the day prior, adjusting the characterization of previous statements, and saying he would support the U.S. children’s vaccination schedule, research and development for bird flu, and scientific data on vaccine safety. 

Kennedy also said he would address rapidly increasing rates of chronic disease. 

“Our country is not going to be destroyed because we get the marginal tax rate wrong. It is going to be destroyed if we get this issue wrong,” he said of chronic diseases. “And I am in a unique position to be able to stop this epidemic.” 

He was asked about comments he has made over decades, including that it was “highly likely” that Lyme disease was a military bioweapon. He said he never said that it was definitively created in a biolab.   

He would not answer a question from Senator Bernie Sanders about whether he agreed that vaccines do not cause autism. He also said he did not know if the coronavirus vaccine saved millions of lives. 

“If you come out unequivocally, ‘vaccines are safe, it does not cause autism’ that would have an incredible impact,” Cassidy said.   

Kennedy has said vaccines are linked to autism, and he opposed state and federal restrictions imposed during the COVID-19 pandemic. The causes of autism are unclear, though theories that childhood vaccines cause autism have been widely debunked and are contrary to scientific evidence.   

Kennedy, who founded the anti-vaccine group Children’s Health Defense, argued during both hearings that he was not against vaccines. The group has sued in state and federal courts over vaccines. 

“News reports and many in the hearing yesterday have claimed that I’m anti-vaccine and anti-industry. Well, I’m neither,” Kennedy said, repeating that his children are vaccinated.   

Thursday’s hearing in front of the Senate Committee on Health, Education, Labor and Pensions is a courtesy hearing with no vote involved. However, Republican Senators Cassidy, Lisa Murkowski and Susan Collins sit on the committee, all of whom are seen as potential swing votes against Kennedy. 

Supporters of Kennedy wearing “Make America Healthy Again” hats crowded around the committee hearing room on Thursday, while some opposing his confirmation wore “Reject RFK Jr” stickers on their shirts. 

‘Catastrophic’ impacts   

If confirmed, Kennedy would run HHS, which oversees more than $3 trillion in healthcare spending, including at the Food and Drug Administration and the agency in charge of the Medicare and Medicaid health insurance programs covering nearly half of all Americans.   

He said he would follow Trump’s direction on abortion and would hire for his department those who are against abortion rights.   

Kennedy also said gender-affirming care for children has “catastrophic” impacts and that children are not equipped to make judgments about receiving such care. He said he would rescind a Biden-era rule that requires medical providers who receive federal funding to offer gender-affirming care.   

Kennedy said farmers should be offered an off-ramp from chemically intensive agriculture, and that illness in farm communities is “undoubtedly” related to the use of pesticides. Some farm and food groups have expressed concern about Kennedy’s positions on pesticides and food additives.   

Opposition groups have ramped up their efforts to persuade Republican senators to vote against Kennedy. Caroline Kennedy, another member of the storied American political family, on Tuesday urged senators to vote against her cousin’s nomination, calling him a predator with dangerous views on health care. 

Kennedy has also faced scrutiny over his ties to Wisner Baum, a law firm specializing in pharmaceutical drug injury cases. He has an arrangement to earn 10% of fees awarded in contingency cases he refers to the firm, according to a letter Kennedy wrote to an HHS ethics official released last week. 

If confirmed, Kennedy would retain that financial interest in cases that do not directly impact the U.S. government, the letter said.   

If his nomination goes to the full Senate, Kennedy would need the support of at least 50 senators, which would allow Vice President JD Vance to cast another tie-breaking vote to confirm his nomination.

Uganda confirms Ebola outbreak in capital Kampala, one dead

Kampala, Uganda — Uganda has confirmed an outbreak of Ebola virus disease in the capital Kampala, with the first confirmed patient dying from the disease on Wednesday, the health ministry said on Thursday.

The patient, a nurse at the Mulago referral hospital in the capital, had initially sought treatment at various facilities, including Mulago after developing fever-like symptoms.

“The patient experienced multi-organ failure and succumbed to the illness at Mulago National Referral Hospital on Jan 29. Post-mortem samples confirmed Sudan Ebola Virus Disease (strain),” the ministry said.

The highly infectious hemorrhagic fever is transmitted through contact with infected bodily fluids and tissue. Symptoms include headache, vomiting blood, muscle pains and bleeding.

Uganda last suffered an outbreak in late 2022 and that outbreak was declared over on Jan. 11, 2023, after nearly four months in which it struggled to contain the viral infection.

The last outbreak killed 55 of the 143 people infected and the dead included six health workers.

Microsoft, Meta CEOs defend hefty AI spending after DeepSeek stuns tech world

Days after Chinese upstart DeepSeek revealed a breakthrough in cheap AI computing that shook the U.S. technology industry, the chief executives of Microsoft and Meta defended massive spending that they said was key to staying competitive in the new field.

DeepSeek’s quick progress has stirred doubts about the lead America has in AI with models that it claims can match or even outperform Western rivals at a fraction of the cost, but the U.S. executives said on Wednesday that building huge computer networks was necessary to serve growing corporate needs.

“Investing ‘very heavily’ in capital expenditure and infrastructure is going to be a strategic advantage over time,” Meta CEO Mark Zuckerberg said on a post-earnings call.

Satya Nadella, CEO of Microsoft, said the spending was needed to overcome the capacity constraints that have hampered the technology giant’s ability to capitalize on AI.

“As AI becomes more efficient and accessible, we will see exponentially more demand,” he said on a call with analysts.

Microsoft has earmarked $80 billion for AI in its current fiscal year, while Meta has pledged as much as $65 billion towards the technology.

That is a far cry from the roughly $6 million DeepSeek said it has spent to develop its AI model. U.S. tech executives and Wall Street analysts say that reflects the amount spent on computing power, rather than all development costs.

Still, some investors seem to be losing patience with the hefty spending and lack of big payoffs.

Shares of Microsoft — widely seen as a front runner in the AI race because of its tie to industry leader OpenAI – were down 5% in extended trading after the company said that growth in its Azure cloud business in the current quarter would fall short of estimates.

“We really want to start to see a clear road map to what that monetization model looks like for all of the capital that’s been invested,” said Brian Mulberry, portfolio manager at Zacks Investment Management, which holds shares in Microsoft.

Meta, meanwhile, sent mixed signals about how its bets on AI-powered tools were paying off, with a strong fourth quarter but a lackluster sales forecast for the current period.

“With these huge expenses, they need to turn the spigot on in terms of revenue generated, but I think this week was a wake-up call for the U.S.” said Futurum Group analyst Daniel Newman.

“For AI right now, there’s too much capital expenditure, not enough consumption.”

There are some signs though that executives are moving to change that.

Microsoft CFO Amy Hood said the company’s capital spending in the current quarter and the next would remain around the $22.6 billion level seen in the second quarter.

“In fiscal 2026, we expect to continue to invest against strong demand signals. However, the growth rate will be lower than fiscal 2025 (which ends in June),” she said.

Generative AI makes Chinese, Iranian hackers more efficient, report says

A report issued Wednesday by Google found that hackers from numerous countries, particularly China, Iran and North Korea, have been using the company’s artificial intelligence-enabled Gemini chatbot to supercharge cyberattacks against targets in the United States.

The company found — so far, at least — that access to publicly available large language models (LLMs) has made cyberattackers more efficient but has not meaningfully changed the kind of attacks they typically mount.

LLMs are AI models that have been trained, using enormous amounts of previously generated content, to identify patterns in human languages. Among other things, this makes them adept at producing high-functioning, error-free computer programs.

“Rather than enabling disruptive change, generative AI allows threat actors to move faster and at higher volume,” the report found.

Generative AI offered some benefits for low-skilled and high-skilled hackers, the report said.

“However, current LLMs on their own are unlikely to enable breakthrough capabilities for threat actors. We note that the AI landscape is in constant flux, with new AI models and agentic systems emerging daily. As this evolution unfolds, [the Google Threat Intelligence Group] anticipates the threat landscape to evolve in stride as threat actors adopt new AI technologies in their operations.”

Google’s findings appear to agree with previous research released by other large U.S. AI players OpenAI and Microsoft, which found a similar failure to achieve novel offensive strategies for cyberattacks through the use of public generative AI models.

The report clarified that Google works to disrupt the activity of threat actors when it identifies them.

Game unchanged 

“AI, so far, has not been a game changer for offensive actors,” Adam Segal, director of the Digital and Cyberspace Policy Program at the Council on Foreign Relations, told VOA. “It speeds up some things. It gives foreign actors a better ability to craft phishing emails and find some code. But has it dramatically changed the game? No.”

Whether that might change in the future is unclear, Segal said. Also unclear is whether further developments in AI technology will more likely benefit people building defenses against cyberattacks or the threat actors trying to defeat them.

“Historically, defense has been hard, and technology hasn’t solved that problem,” Segal said. “I suspect AI won’t do that, either. But we don’t know yet.”

Caleb Withers, a research associate at the Center for a New American Security, agreed that there is likely to be an arms race of sorts, as offensive and defensive cybersecurity applications of generative AI evolve. However, it is likely that they will largely balance each other out, he said.

“The default assumption should be that absent certain trends that we haven’t yet seen, these tools should be roughly as useful to defenders as offenders,” he said. “Anything productivity enhancing, in general, applies equally, even when it comes to things like discovering vulnerabilities. If an attacker can use something to find a vulnerability in software, so, too, is the tool useful to the defender to try to find those themselves and patch them.”

Threat categories

The report breaks down the kinds of threat actors it observed using Gemini into two primary categories.

Advanced persistent threat (APT) actors refer to “government-backed hacking activity, including cyber espionage and destructive computer network attacks.” By contrast, information operation (IO) threats “attempt to influence online audiences in a deceptive, coordinated manner. Examples include sock puppet accounts [phony profiles that hide users’ identities] and comment brigading [organized online attacks aimed at altering perceptions of online popularity].”

The report found that hackers from Iran were the heaviest users of Gemini in both threat categories. APT threat actors from Iran used the service for a wide range of tasks, including gathering information on individuals and organizations, researching targets and their vulnerabilities, translating language and creating content for future online campaigns.

Google tracked more than 20 Chinese government-backed APT actors using Gemini “to enable reconnaissance on targets, for scripting and development, to request translation and explanation of technical concepts, and attempting to enable deeper access to a network following initial compromise.”

North Korean state-backed APTs used Gemini for many of the same tasks as Iran and China but also appeared to be attempting to exploit the service in its efforts to place “clandestine IT workers” in Western companies to facilitate the theft of intellectual property.

Information operations

Iran was also the heaviest user of Gemini when it came to information operation threats, accounting for 75% of detected usage, Google reported. Hackers from Iran used the service to create and manipulate content meant to sway public opinion, and to adapt that content for different audiences.

Chinese IO actors primarily used the service for research purposes, looking into matters “of strategic interest to the Chinese government.”

Unlike the APT sector, where their presence was minimal, Russian hackers were more common when it came to IO-related use of Gemini, using it not only for content creation but to gather information about how to create and use online AI chatbots.

Call for collaboration

Also on Wednesday, Kent Walker, president of global affairs for Google and its parent company, Alphabet, used a post on the company’s blog to note the potential dangers posed by threat actors using increasingly sophisticated AI models, and calling on the industry and federal government “to work together to support our national and economic security.”

“America holds the lead in the AI race — but our advantage may not last,” Walker wrote.

Walker argued that the U.S. needs to maintain its narrow advantage in the development of the technology used to build the most advanced artificial intelligence tools. In addition, he said, the government must streamline procurement rules to “enable adoption of AI, cloud and other game-changing technologies” by the U.S. military and intelligence agencies, and to establish public-private cyber defense partnerships.
