TORONTO — Scientists have long known that light can sometimes appear to exit a material before entering it — an effect dismissed as an illusion caused by how waves are distorted by matter.

Now, researchers at the University of Toronto, through innovative quantum experiments, say they have demonstrated that “negative time” isn’t just a theoretical idea, it exists in a tangible, physical sense, deserving closer scrutiny.

The findings, yet to be published in a peer-reviewed journal, have attracted both global attention and skepticism.

The researchers emphasize that these perplexing results highlight a peculiar quirk of quantum mechanics rather than a radical shift in our understanding of time.

“This is tough stuff, even for us to talk about with other physicists. We get misunderstood all the time,” said Aephraim Steinberg, a University of Toronto professor specializing in experimental quantum physics.

While the term “negative time” might sound like a concept lifted from science fiction, Steinberg defends its use, hoping it will spark deeper discussions about the mysteries of quantum physics.

Years ago, the team began exploring interactions between light and matter.

When light particles, or photons, pass through atoms, some are absorbed by the atoms and later re-emitted. This interaction changes the atoms, temporarily putting them in a higher-energy or “excited” state before they return to normal.

In research led by Daniela Angulo, the team set out to measure how long these atoms stayed in their excited state.

“That time turned out to be negative,” Steinberg said, meaning a duration less than zero.

To visualize this concept, imagine cars entering a tunnel: Before the experiment, physicists recognized that while the average entry time for 1,000 cars might be, for example, noon, the first cars could exit a little sooner, say 11:59 a.m. This result was previously dismissed as meaningless.

What Angulo and colleagues demonstrated was akin to measuring carbon monoxide levels in the tunnel after the first few cars emerged and finding that the readings had a minus sign in front of them.

The experiments, conducted in a cluttered basement laboratory bristling with wires and aluminum-wrapped devices, took over two years to optimize. The lasers used had to be carefully calibrated to avoid distorting the results.

Still, Steinberg and Angulo are quick to clarify: No one is claiming time travel is a possibility.

“We don’t want to say anything traveled backward in time,” Steinberg said. “That’s a misinterpretation.”

The explanation lies in quantum mechanics, where particles like photons behave in fuzzy, probabilistic ways rather than following strict rules.

Instead of adhering to a fixed timeline for absorption and re-emission, these interactions occur across a spectrum of possible durations, some of which defy everyday intuition.

Critically, the researchers say, this doesn’t violate Einstein’s theory of special relativity, which dictates that nothing can travel faster than light. These photons carried no information, sidestepping any cosmic speed limits.

The concept of “negative time” has drawn both fascination and skepticism, particularly from prominent voices in the scientific community.

German theoretical physicist Sabine Hossenfelder, for one, criticized the work in a YouTube video viewed by more than 250,000 people, noting, “The negative time in this experiment has nothing to do with the passage of time — it’s just a way to describe how photons travel through a medium and how their phases shift.”

Angulo and Steinberg pushed back, arguing that their research addresses crucial gaps in understanding why light doesn’t always travel at a constant speed.

Steinberg acknowledged the controversy surrounding their paper’s provocative headline but pointed out that no serious scientist has challenged the experimental results.

“We’ve made our choice about what we think is a fruitful way to describe the results,” he said, adding that while practical applications remain elusive, the findings open new avenues for exploring quantum phenomena.

NEW YORK — The U.S. flu season is under way, with cases surging across much of the country, health officials said Friday. 

The Centers for Disease Control and Prevention noted sharp increases in several measures, including lab tests and emergency room visits. 

“It’s been increasing at a pretty steady pace now for the past several weeks. So yeah, we are certainly in flu season now,” said the CDC’s Alicia Budd. 

Thirteen states reported high or very high levels of flu-like illness last week, about double from the week before. One is Tennessee, where a sickness spike is hitting the Nashville area, said Dr. William Schaffner, an infectious diseases expert at Vanderbilt University. 

“Flu has been increasing, but just this last week has exploded,” Schaffner said. He noted that in a local clinic that serves as an indicator of illness trends, as many as a quarter of the patients have flu symptoms. 

Louisiana is another early hot spot. 

“Just this week is really that turning point where people are out because of the flu,” said Dr. Catherine O’Neal, an infectious diseases doctor at the largest private hospital in the state, Our Lady of the Lake Regional Medical Center in Baton Rouge. “You hear parents saying, ‘I can’t come to work because of the flu’ and ‘Where can I get a flu test?’” 

There are a number of bugs that cause fever, cough, sore throat and other flu-like symptoms. One is COVID-19. Another is RSV, or respiratory syncytial virus, which is a common cause of cold-like symptoms but can be dangerous for infants and the elderly. 

The most recent CDC data show COVID-19 hospitalizations have been declining since summer. COVID-19 activity is moderate nationally, but high in the Midwest, according to CDC wastewater data. 

RSV hospitalizations started rising before flu did and now show signs of possibly leveling off, but they remain a little more common than admissions for flu. Overall, RSV activity is low nationally, but high in the South, the wastewater data show. 

The CDC called the start of flu season based on several indicators, including lab results for patients in hospitals and doctor’s offices, and the percentage of emergency department visits that had a discharge diagnosis of flu. 

No flu strain seems to be dominant, and it’s too early in the season to know how good a match the flu vaccine will be, Budd said. 

Last winter’s flu season was considered “moderate” overall, but it was long — 21 weeks — and the CDC estimated there were 28,000 flu-related deaths. It was unusually dangerous for children, with 205 pediatric deaths reported. That was the highest number ever reported for a conventional flu season. 

The long season was likely a factor, Budd said. Another factor was a lack of flu vaccinations. Among the children who died who were old enough for flu vaccinations — and for whom their vaccination status was known — 80% were not fully vaccinated, according to the CDC. 

Vaccination rates for children are even lower this year. As of Dec. 7, about 41% of adults had received a flu vaccination, similar to the rate at the same point last year. The percentage is the same for kids, but for them that’s a drop from a year ago, when 44% were vaccinated against the flu, according to CDC data. 

Vaccination rates are lower still against COVID-19, with about 21% of adults and 11% of children up to date. 

Flu experts suggest everyone get vaccinated, especially as people prepare to attend holiday gatherings where respiratory viruses can spread widely. 

“All those gatherings that are so heartwarming and fun and joyous are also an opportunity for this virus to spread person to person,” Schaffner said. “It’s not too late to get vaccinated.”

As new potential threats from Chinese hackers were identified this week, the federal government issued one of its strongest warnings to date about the need for Americans — and in particular government officials and other “highly targeted” individuals — to secure their communications against eavesdropping and interception.

The warning came as news was breaking about a Commerce Department investigation into the possibility that computer network routers manufactured by the Chinese firm TP-Link may pose a threat to the millions of U.S. businesses, households and government agencies that use them.

Also on Wednesday, Congress took long-awaited steps toward funding a program that will purge other Chinese technology from U.S. telecommunications systems. The so-called rip-and-replace program targets gear manufactured by Chinese firms Huawei and ZTE.

Too far behind

While experts said the recent actions are a step in the right direction, they warned that U.S. policymakers have been extremely slow to react to a mountain of evidence that Chinese hackers have long been targeting essential communications and infrastructure systems in the U.S.

The lack of action has persisted despite law enforcement and intelligence agencies repeatedly sounding alarms.

In January, while testifying before the House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party, FBI Director Christopher Wray said, “There has been far too little public focus on the fact that [People’s Republic of China] hackers are targeting our critical infrastructure — our water treatment plants, our electrical grid, our oil and natural gas pipelines, our transportation systems. And the risk that poses to every American requires our attention now.”

A year previously, Wray had warned lawmakers on the House Appropriations Committee that his investigators were badly outnumbered.

“To give you a sense of what we’re up against, if each one of the FBI’s cyber agents and intel analysts focused exclusively on the China threat, Chinese hackers would still outnumber FBI Cyber personnel by at least 50-to-1,” Wray said.

Decades of complexity

Part of the problem, experts said, is that it is difficult for policymakers to summon the political will to make changes that could be disruptive to the lives and livelihoods of U.S. citizens in the absence of public concern about the problem.

“It still remains very, very difficult to impress upon average, typical everyday citizens the gravity of Chinese espionage, or the extent of it,” said Bill Drexel, a fellow with the Technology and National Security Program at the Center for a New American Security.

He contrasted the relatively muted public response to the recent revelation of a Chinese hacking operation known as Salt Typhoon, which compromised mobile telephone networks throughout the country, with the uproar that accompanied the far less serious appearance of a Chinese spy balloon over the U.S. mainland in 2023.

“That just goes to show this … problem where really grave issues that are intangible — that are just in cyberspace — are really hard to wrap our minds around,” Drexel told VOA.

“For four decades, we intertwined our supply chains very deeply with China, and our digital systems became more and more complex, allowing more and more compounding ways to be hacked, to be compromised,” Drexel said.

“We’ve just started to try to change course on this stuff,” he added. “But there’s so much momentum for so long on these issues, and they continue to compound in complexity, such that it’s just really hard to catch up.”

Warning ‘highly targeted’ Americans

The Cybersecurity and Infrastructure Security Agency (CISA) issued guidance on Wednesday, reporting that it “has identified cyber espionage activity by People’s Republic of China (PRC) government-affiliated threat actors targeting commercial telecommunications infrastructure.”

It continued, “This activity enabled the theft of customer call records and the compromise of private communications for a limited number of highly targeted individuals.”

The warning appeared to be related to the Salt Typhoon hack that, according to government investigators, compromised all the major mobile phone carriers in the U.S., giving the Chinese government extraordinary access to the communications among millions of Americans.

The five-page CISA document outlines steps that the agency advises all Americans, but particularly those most likely to be targeted, to take immediately.

The first is to immediately curtail use of standard mobile communications platforms, such as voice calls and Short Message Service (SMS) texting. Instead, the agency advises Americans to restrict their communications to free messaging platforms that offer end-to-end encryption, such as Signal, which support one-on-one and group chats, as well as voice and video calls. Data sent with end-to-end encryption is extremely difficult to decrypt, even if a malicious actor is able to intercept it during transmission.

Among the other advice CISA offered was to avoid using SMS messages for multifactor authentication by switching to apps that provide authenticator codes or, where possible, adopting hardware-based security keys for highly sensitive accounts. Other recommendations included the use of complex and random passwords stored in password manager software, as well as platform-specific suggestions for iPhone and Android users.

TP-Link concerns

On Wednesday, The Wall Street Journal reported, and other outlets subsequently confirmed, that the Commerce Department, as well as the Justice and Defense departments, are investigating reports that computer routers manufactured by the Shenzhen-based TP-Link are one vector of attack for Chinese hackers.

TP-Link currently dominates the market for computer routers in the U.S., with nearly two-thirds of total market share. In October, a report from Microsoft revealed that one Chinese hacking operation it identified as CovertNetwork-1658 has compromised thousands of TP-Link routers to create a network that is used by “multiple Chinese threat actors” to gain illicit access to computer networks around the world.

The Journal’s reporting also revealed that the Commerce Department is considering a ban on the sale of TP-Link routers in the U.S. next year, an action that could significantly disrupt the U.S. market for networking hardware.

Rip and replace

Congress on Wednesday took long-delayed action to address a different potential threat from China, allocating $3 billion to a program that will remove telecommunications equipment manufactured by Huawei and ZTE from rural telecommunications networks in the U.S.

Funding for the rip-and-replace program arrives years after the U.S. identified the two companies as posing a potential threat.

Beginning in the first Trump administration and continuing during Joe Biden’s time in office, the U.S. pressured allies around the world to block the installation of Huawei and ZTE 5G cellular communications equipment from their networks, in some cases threatening to stop sharing sensitive intelligence with allies that failed to comply.

washington — Experts on cybersecurity and online foreign influence campaigns are urging social media company Bluesky, whose app has exploded in popularity in recent weeks, to step up moderation to counter potential state-sponsored influence efforts.

Over the past month, Bluesky, a microblogging platform with its roots in Twitter, has seen one of its biggest increases in new user registrations since it was publicly released in February. Over 25 million are now on the platform, close to half of whom joined after the 2024 U.S. presidential election.

Rose Wang, Bluesky’s chief operating officer, said in a recent interview that Bluesky does not intend to push any political ideologies.

“We have no political viewpoint that we are trying to promote,” she said in early December.

Exploiting users’ political leanings

Many who joined Bluesky have cited user experience as one of the reasons for migrating from social media platform X. They also have said they joined the platform after Election Day because they are critics of Elon Musk and President-elect Donald Trump. Some commentators in the U.S. have questioned whether Bluesky is risking becoming an echo chamber of the left.

Some experts contend the platform’s liberal-leaning users could be exploited by foreign propagandists. Joe Bodnar, who tracks foreign influence operations for the Institute for Strategic Dialogue, told VOA Mandarin that Russian propaganda often appeals to the anti-establishment left in the U.S. on contentious topics, like Gaza, gun violence and America’s global dominance.

“The Kremlin wants to make those arguments even louder,” Bodnar said. “Sometimes that means they play to the left.”

So far, at least three accounts that belong to RT, a Russia-controlled media outlet, have joined Bluesky. Sputnik Brazil is also actively posting on the platform.

VOA Mandarin found that at least two Chinese accounts that belong to state broadcaster CGTN have joined the platform.

Bluesky does not assign verification labels. One way to authenticate an account is for the person or organization to link it to the domain of its official website.

There are at least four other accounts that claim to be Chinese state media outlets, including China Daily, the Global Times and People’s Daily. None of the three publications replied to VOA’s emails inquiring about these accounts’ authenticity.

Additionally, Beijing has played heavily to the Western left on certain global issues. China has consistently called for a ceasefire in Gaza and blamed the West for supporting Israel.

But those familiar with Chinese and Russian state media say the left-leaning user base on Bluesky actually could give Beijing and Moscow a hard time for pushing their narratives.

“Bluesky isn’t the most hospitable place for Russian narratives,” Bodnar said.

Sean Haines, a British national who used to work for Chinese state media outlets, shared similar opinions in a recent blog post about Bluesky.

“With its predominately Western liberal leaning, the platform also will be an uphill challenge for those looking to push overtly nationalistic viewpoints,” he wrote.

Most of the Chinese and Russian state media accounts have only hundreds of followers, with RT en Espanol at the top, with nearly 7,000.

Could ‘decentralization’ be detrimental?

China and Russia have been finding ways to reach the American public through covert disinformation operations on social media. During this year’s election, disinformation campaigns connected to China and Russia promoted claims that cast doubt on the integrity of the voting process.

Similar tactics could soon be coming to Bluesky.

“I don’t think Bluesky is more vulnerable to influence campaigns than X or other social networks,” Jennifer Victoria Scurrell, a researcher on AI-supported influence operations, told VOA Mandarin. But Scurrell, of ETH Zurich’s Center for Security Studies, said Bluesky’s decentralized moderation approach is flawed.

Jack Dorsey, the founder of Twitter, started Bluesky as an internal project to give users more power over moderation. Bluesky then went independent in 2021.

“Our mission is to develop and drive large-scale technologies of open and decentralized public conversation,” the company says on its website.

To do that, Bluesky “decentralized” its moderation authority, giving users tools to customize their experience on the site.

Bluesky offers a universal basic moderation setting for every user, which labels content such as extremism, misinformation, fake accounts and adult content. Users can choose whether to see the content labeled by Bluesky. Users can report to Bluesky content or accounts they believe have violated Bluesky’s guidelines.

On top of that, users get to create their own moderation settings to label or filter out certain content and accounts. Other users can subscribe to these customized settings, should they choose.

Scurrell, who helps test security weaknesses for OpenAI as a contractor, told VOA Mandarin the decentralized approach to moderation could be a double-edged sword.

“Societal values are diverse, contextual and local, which makes decentralized moderation an appealing concept,” she wrote in her replies to VOA.

She warned that outsourcing content moderation to users, though, “raises serious concerns” because the approach would give bad actors the same amount of power as normal users.

“What happens if an entire node is taken over by malicious actors spreading disinformation or manipulative content,” she wrote, or “if the system gets hijacked by an army of bots?”

VOA Mandarin emailed Bluesky a list of detailed questions about its moderation policy against potential foreign influence attempts but did not receive a response.

Experts have urged Bluesky to implement measures to counter potential foreign influence campaigns.

In a recent blog post, Sarah Cook, an independent China watcher and former China director at Freedom House, urged Bluesky to label state media accounts, a practice exercised by many social media companies, so users know of these accounts’ ties to foreign governments.

Eugenio Benincasa, an expert on Chinese cyber threats at ETH Zurich, asserts that studying how Chinese tech companies help Beijing surveil social media platforms and manipulate online discussions can help Bluesky better prepare.

“It is crucial to thoroughly study the evolving influence tactics enabled by tools like public opinion monitoring systems to identify vulnerabilities that may have been overlooked or are emerging, in order to develop effective safeguards,” Benincasa said.

WASHINGTON — The U.S. cybersecurity watchdog CISA is telling senior American government officials and politicians to immediately switch to end-to-end encrypted messaging following intrusions at major American telecoms blamed on Chinese hackers. 

In written guidance released on Wednesday, the Cybersecurity and Infrastructure Security Agency said “individuals who are in senior government or senior political positions” should “immediately review and apply” a series of best practices around the use of mobile devices. 

The first recommendation: “Use only end-to-end encrypted communications.” 

End-to-end encryption — a data protection technique that aims to make data unreadable by anyone except its sender and its recipient — is baked into various chat apps, including Meta Platforms’ WhatsApp, Apple’s iMessage, and the privacy-focused app Signal. Corporate offerings, which allow end-to-end encryption, also include Microsoft’s Teams and Zoom Communications’ meetings. 

CISA’s message is the latest in a series of increasingly stark warnings issued by American officials in the wake of dramatic hacks of U.S. telecom companies by a group dubbed “Salt Typhoon.” 

Last week, Democratic Senator Ben Ray Lujan said, “this attack likely represents the largest telecommunications hack in our nation’s history.” 

U.S. officials have blamed China for the hacking. Beijing routinely denies allegations of cyberespionage.

GENEVA — International human and animal health experts warn the H5N1 avian influenza is evolving quickly and posing a global health threat as the virus is increasingly crossing species barriers and infecting a wide range of domestic and wild mammals.

“These developments pose significant challenges to animal, human and environmental health,” Dr. Gregorio Torres, veterinarian and head of the science department at the World Organization for Animal Health, told journalists in Geneva Tuesday.

He noted that avian influenza, commonly known as bird flu, has been reported in 108 countries and territories over five continents in the last three years.

“And as of December 2024, the infection has been detected in over 70 species of domestic and wild mammals. This includes the ongoing detection of H5N1 in dairy cattle in the United States,” Torres said.

“So far, the close monitoring of the virus has not found markers that could suggest effective mammalian adaptation, but we know this can change at any time,” he said.

Most human cases in US

The World Health Organization this week reported 76 people were infected with the H5 avian influenza viruses in 2024, most of them among farm workers. Sixty-one of these cases occurred in the United States, which has reported outbreaks in wildlife, poultry and, more recently, dairy cattle.

“This is the first time we have seen the infections from dairy cattle to humans, and so many within the U.S.” said Dr. Maria Van Kerkhove, director of epidemic and pandemic threat management at WHO.

“In the U.S., all but two have direct links with infected animals, whether this was working on farms, whether this was part of culling exercises,” she said. “We have not seen any detection of human-to-human transmission among these cases.”

While much attention on the bird flu situation has focused on the United States this year, Van Kerkhove noted that Australia, Cambodia, Canada, China and Vietnam also reported outbreaks.

Based on available information, she said that the H5N1 viruses have remained avian viruses and have not adapted to spread among people, stressing that follow-up epidemiologic, virologic and serologic investigations “so far have not reported or identified human-to-human transmission.”

“However, this can change quickly as the virus is evolving, which is why we are actively assessing the situation and why surveillance is so critical,” she said.

300 million birds dead

Although the WHO assesses the current risk of infection for the public as low, it considers the public health risk for farm workers and others exposed to infected animals to be low-to-moderate. The WHO advises exposed groups to use personal protective equipment such as coveralls, respirator masks, eye protection, gloves and boots to minimize the risk.

Since October 2021, H5N1 has caused the deaths of more than 300 million birds worldwide, affecting the livelihood of millions of people.

“In addition to the direct impact on livelihoods, the economic burden on farmers can lead to reduced investments in biosecurity measures,” said Madhur Dhingra, the U.N. Food and Agriculture Organization’s senior infectious diseases animal health officer.

“This increases the risk and leads to a dangerous cycle of risk, vulnerability, and loss. … In regions heavily reliant on poultry as a primary protein source, HPAI [highly pathogenic avian influenza] poses a serious threat to food and nutrition security,” she said.

“The impacts of HPAI have spilled over into wildlife, with more than 500 bird species and over 70 mammalian species affected, including endangered animals like the California condor and polar bears,” she said. “The biodiversity impacts, particularly among seabirds and marine mammals, and disruption of fragile ecosystems, such as the Antarctic region, are concerning.”

Health experts agree that increased surveillance and close monitoring of the evolution of the H5N1 virus are essential to prevent the disease from spreading widely around the world.

“We are in an interpandemic period right now where we have a number of different zoonotic viruses, with avian influenza, H5N1 one of several,” Van Kerkhove said.

“While we are operating in a state of readiness, I think the world is not ready for another infectious disease, massive outbreak or pandemic because we have lived through COVID and it was incredibly traumatic, and it is still ongoing.

“We are recommending to our member states and national authorities to increase surveillance and vigilance in human populations, especially those who are occupationally exposed, for the possibility for infection, and, of course, doing thorough investigations around each and every human case,” she said.

In the meantime, she advised people to minimize their risk of becoming sick from bird flu by carefully watching what they eat and drink.

“Cows infected with the H5N1 virus have been reported to have high viral loads in their milk,” she said, so, it is advisable that people “consume pasteurized milk.”

“If pasteurized milk is not available, heating milk until it boils also makes it safe for consumption. Similarly, we recommend thoroughly cooking meat and eggs when in areas affected by avian flu outbreaks,” she said.

WASHINGTON — The U.S. Supreme Court decided on Wednesday to hear a bid by TikTok and its China-based parent company, ByteDance, to block a law intended to force the sale of the short-video app by January 19 or face a ban on national security grounds. 

The justices did not immediately act on an emergency request by TikTok and ByteDance, as well as by some of its users who post content on the social media platform, for an injunction to halt the looming ban, opting instead to hear arguments on the matter on January 10.  

The challengers are appealing a lower court’s ruling that upheld the law. TikTok is used by about 170 million Americans. 

Congress passed the measure in April and President Joe Biden, a Democrat, signed it into law. The Justice Department had said that as a Chinese company, TikTok poses “a national-security threat of immense depth and scale” because of its access to vast amounts of data on American users, from locations to private messages, and its ability to secretly manipulate content that Americans view on the app. TikTok has said it poses no imminent threat to U.S. security.  

TikTok and ByteDance asked the Supreme Court on December 16 to pause the law, which they said violates free speech protections under the U.S. Constitution’s First Amendment.  

TikTok on Wednesday said it was pleased the court will take up the issue. “We believe the court will find the TikTok ban unconstitutional so the over 170 million Americans on our platform can continue to exercise their free speech rights,” the company said. 

The companies said that being shuttered for even one month would cause TikTok to lose about a third of its U.S. users and undermine its ability to attract advertisers and recruit content creators and employee talent. 

The U.S. Court of Appeals for the District of Columbia Circuit in Washington on December 6 rejected the First Amendment arguments by the companies.  

In their filing to the Supreme Court, TikTok and ByteDance said that “if Americans, duly informed of the alleged risks of ‘covert’ content manipulation, choose to continue viewing content on TikTok with their eyes wide open, the First Amendment entrusts them with making that choice, free from the government’s censorship.” 

Senate Republican leader Mitch McConnell on Wednesday, in a brief filed with the Supreme Court, urged the court to reject any delay, comparing TikTok to a hardened criminal. 

A U.S. ban on TikTok would make the company far less valuable to ByteDance and its investors, and hurt businesses that depend on TikTok to drive their sales. 

Republican President-elect Donald Trump, who unsuccessfully tried to ban TikTok during his first term in the White House in 2020, has reversed his stance and promised during the presidential race this year that he would try to save TikTok. Trump said on Dec. 16 that he has “a warm spot in my heart for TikTok” and that he would “take a look” at the matter. 

Trump takes office on January 20, the day after the TikTok deadline under the law. 

In its decision, the D.C. Circuit wrote, “The First Amendment exists to protect free speech in the United States. Here the government acted solely to protect that freedom from a foreign adversary nation and to limit that adversary’s ability to gather data on people in the United States.” 

TikTok has denied it has or ever would share U.S. user data, accusing U.S. lawmakers in the lawsuit of advancing speculative concerns. It has characterized the ban as a “radical departure from this country’s tradition of championing an open Internet.”  

The dispute comes at a time of growing trade tensions between the world’s two biggest economies after the Biden administration placed new restrictions on the Chinese chip industry and China responded with a ban on exports of gallium, germanium and antimony, metals which are used in making high-tech microchips, to the United States. 

The U.S. law would bar providing certain services to TikTok and other foreign adversary-controlled apps including offering it through app stores such as Apple and Alphabet’s Google, effectively preventing TikTok’s continued U.S. use unless ByteDance divests TikTok by the deadline. 

An unimpeded ban could open the door to a future crackdown on other foreign-owned apps. In 2020, Trump had also tried to ban WeChat, owned by Chinese company Tencent, but was blocked by the courts.

HARARE, ZIMBABWE — A Zimbabwean national park is hosting relocated wildlife from a game park just outside the country’s capital after an autopsy report on Saturday confirmed that four rhinos and several other animals died after drinking contaminated lake water.

Tinashe Farawo, the spokesperson for the Zimbabwe Parks and Wildlife Management Authority, confirmed to VOA the death of four rhinos after drinking bacteria-polluted water at Lake Chivero Recreational Park, about 20 kilometers west of the capital, Harare.

“We are not only losing the rhinos, but [we] also lost some zebras, wildebeest and some birds,” Farawo said.

“We have tried to treat some of the rhinos, but unfortunately it seems like we are not managing at the moment. But we have made some temporary collective measures to make sure we do the best we can with this challenge,” he said, referring to the temporary transfer of wildlife away from the lake.

“We need to continue to make sure that at least we deal with the issue of pollution around Lake Chivero,” Farawo said.

Amkela Sidange, spokesperson for the Environmental Management Agency of Zimbabwe, said that, nationwide, about 415 megaliters of untreated sewage are being discharged into the environment daily.

The “city of Harare on its own … contributes about 219 megaliters of raw and partly treated sewer that is discharged into the environment on a daily basis, and that goes to show how huge the crisis is,” she said.

“We need the whole of government and societal approach,” Sidange said, adding that temporary solutions aren’t getting the job done.

Harare Mayor Jacob Mafume said he is counting on the central government to provide money to help the city provide proper sewer services, especially for those who live in “informal settlements.”

“We have over 150,000 informal settlements, and these informal settlements do not have sewer reticulation systems,” he said. “Therefore, their discharge is going straight into our water bodies.”

While the bickering continues among high-ranking officials about who is polluting Harare water with cyanobacteria, Farai Maguwu, director of the Center for Natural Resource Governance, is worried about the residents of Zimbabwe’s capital.

“There is a need to carry out scientific investigations about the water that is pumped into people’s homes by Harare city council and see if that water is still safe for drinking and inform the citizens of Harare accordingly,” Maguwu said.

On Tuesday, Mafume declared that Harare’s water was still meeting the World Health Organization’s standards and was safe for drinking.

The city council provides bottled water during its meetings and, for years now, many residents of Harare drink bottled water and water from boreholes.

Paris — The Democratic Republic of Congo has filed criminal complaints against Apple subsidiaries in France and Belgium, accusing the tech firm of using conflict minerals in its supply chain, lawyers for the Congolese government told Reuters. 

Congo is a major source of tin, tantalum and tungsten, so-called 3T minerals used in computers and mobile phones. But some artisanal mines are run by armed groups involved in massacres of civilians, mass rapes, looting and other crimes, according to U.N. experts and human rights groups. 

Apple does not directly source primary minerals and says it audits suppliers, publishes findings and funds bodies that seek to improve mineral traceability. 

Apple last year said it had “no reasonable basis for concluding” its products contain illegally exported minerals from conflict-hit zones. The tech giant has insisted it carefully verifies the origin of materials in its output. 

Its 2023 filing on conflict minerals to the U.S. Securities and Exchange Commission said none of the smelters or refiners of 3T minerals or gold in its supply chain had financed or benefited armed groups in Congo or neighboring countries. 

But international lawyers representing Congo argue that Apple uses minerals pillaged from Congo and laundered through international supply chains, which they say renders the firm complicit in crimes taking place in Congo. 

In parallel complaints filed to the Paris prosecutor’s office and to a Belgian investigating magistrate’s office on Monday, Congo accuses local subsidiaries Apple France, Apple Retail France and Apple Retail Belgium of a range of offenses. 

These include covering up war crimes and the laundering of tainted minerals, handling stolen goods, and carrying out deceptive commercial practices to assure consumers supply chains are clean. 

“It is clear that the Apple group, Apple France and Apple Retail France know very well that their minerals supply chain relies on systemic wrongdoing,” says the French complaint, after citing U.N. and rights reports on conflict in east Congo. 

Belgium had a particular moral duty to act because looting of Congo’s resources began during the 19th-century colonial rule of its King Leopold II, Congo’s Belgian lawyer Christophe Marchand said. 

“It is incumbent on Belgium to help Congo in its effort to use judicial means to end the pillaging,” he said. 

The complaints, prepared by the lawyers on behalf of Congo’s justice minister, make allegations not just against the local subsidiaries but against the Apple group as a whole. 

France and Belgium were chosen because of their perceived strong emphasis on corporate accountability. Judicial authorities in both nations will decide whether to investigate the complaints further and bring criminal charges. 

In an unrelated case in March, a U.S. federal court rejected an attempt by private plaintiffs to hold Apple, Google, Tesla, Dell and Microsoft accountable for what the plaintiffs described as their dependence on child labor in Congolese cobalt mines. 

Minerals fuel violence 

Since the 1990s, Congo’s mining heartlands in the east have been devastated by waves of fighting between armed groups, some backed by neighboring Rwanda, and the Congolese military. 

Millions of civilians have died and been displaced. 

Competition for minerals is one of the main drivers of conflict as armed groups sustain themselves and buy weapons with the proceeds of exports, often smuggled via Rwanda, according to U.N. experts and human rights organizations. 

Rwanda denies benefiting from the trade, dismissing the allegations as unfounded. 

Among the appendices to Congo’s legal complaint in France was a statement issued by the U.S. State Department in July, expressing concerns about the role of the illicit trade in minerals from Congo, including tantalum, in financing conflict. 

The statement was a response to requests from the private sector for the U.S. government to clarify potential risks associated with manufacturing products using minerals extracted, transported or exported from eastern Congo, Rwanda and Uganda. 

Congo’s complaints focus on ITSCI, a metals industry-funded monitoring and certification scheme designed to help companies perform due diligence on suppliers of 3T minerals exported from Congo, Rwanda, Burundi and Uganda. 

Congo’s lawyers argue that ITSCI has been discredited, including by the Responsible Minerals Initiative (RMI) of which Apple is a member, and that Apple nevertheless uses ITSCI as a fig leaf to falsely present its supply chain as clean. 

The RMI, whose members include more than 500 companies, announced in 2022 it was removing ITSCI from its list of approved traceability schemes. 

In July, it said it was prolonging the suspension until at least 2026, saying ITSCI had not provided field observations from high-risk sites or explained how it was responding to an escalation of violence in North Kivu province, which borders Rwanda and is a key 3T mining area. 

ITSCI criticized the RMI’s own processes and defended its work in Congo as reliable. It has also rejected allegations in a 2022 report by campaigning group Global Witness entitled “The ITSCI Laundromat,” cited in Congo’s legal complaint in France, that it was complicit in the false labeling of minerals from conflict zones as coming from mines located in peaceful areas. 

Apple mentioned ITSCI five times in its 2023 filing on conflict minerals. The filing also made multiple mentions of the RMI, in which Apple said it had continued active participation and leadership but did not mention the RMI’s ditching of ITSCI. 

In its July statement, the U.S. State Department said flaws in traceability schemes have not garnered sufficient engagement and attention to lead to changes needed. 

Robert Amsterdam, a U.S.-based lawyer for Congo, said the French and Belgian complaints were the first criminal complaints by the Congolese state against a major tech company, describing them as a “first salvo” only.

LONDON — European Union regulators said Tuesday they’re investigating whether TikTok breached the bloc’s digital rulebook by failing to deal with risks to Romania’s presidential election, which has been thrown into turmoil over allegations of electoral violations and Russian meddling.

The European Commission is escalating its scrutiny of the popular video-sharing platform after Romania’s top court canceled results of the first round of voting that resulted in an unknown far-right candidate becoming the front-runner.

The court made its unprecedented decision after authorities in the European Union and NATO member country declassified documents alleging Moscow organized a sprawling social media campaign to promote a long-shot candidate, Calin Georgescu.

“Following serious indications that foreign actors interfered in the Romanian presidential elections by using TikTok, we are now thoroughly investigating whether TikTok has violated the Digital Services Act by failing to tackle such risks,” European Commission President Ursula von der Leyen said in a press release. “It should be crystal clear that in the EU, all online platforms, including TikTok, must be held accountable.”

The European Commission is the 27-nation European Union’s executive arm and enforces the bloc’s Digital Services Act, a sweeping set of regulations intended to clean up social media platforms and protect users from risks such as election-related misinformation. It ordered TikTok earlier this month to retain all information related to the election.

In the preliminary round of voting on Nov. 24 Georgescu was an outsider among the 13 candidates but ended up topping the polls. He was due to face a pro-EU reformist rival in a runoff before the court canceled the results.

The declassified files alleged that there was an “aggressive promotion campaign” to boost Georgescu’s popularity, including payments worth a total of $381,000 to TikTok influencers to promote him on the platform.

TikTok said it has “protected the integrity” of its platform over 150 elections around the world and is continuing to address these “industry-wide challenges.”

“TikTok has provided the European Commission with extensive information regarding these efforts, and we have transparently and publicly detailed our robust actions,” it said in a statement.

The commission said its investigation will focus on TikTok’s content recommendation systems, especially on risks related to “coordinated inauthentic manipulation or automated exploitation.” It’s also looking at TikTok’s policies on political advertisements and “paid-for political content.”

TikTok said it doesn’t accept paid political ads and “proactively” removes content for violating policies on misinformation.

The investigation could result in TikTok making changes to fix problems or fines worth up to 6% of the company’s total global revenue.

NEW YORK — An Alabama woman is recovering well after a pig kidney transplant last month that freed her from eight years of dialysis, the latest effort to save human lives with animal organs. 

Towana Looney is the fifth American given a gene-edited pig organ — and notably, she isn’t as sick as prior recipients who died within two months of receiving a pig kidney or heart. 

“It’s like a new beginning,” Looney, 53, told The Associated Press. Right away, “the energy I had was amazing. To have a working kidney — and to feel it — is unbelievable.” 

Looney’s surgery marks an important step as scientists get ready for formal studies of xenotransplantation expected to begin next year, said Dr. Robert Montgomery of NYU Langone Health, who led the highly experimental procedure. 

Looney is recuperating well after her transplant, which was announced Tuesday. She was discharged from the hospital 11 days after surgery to continue recovery in a nearby apartment although temporarily readmitted this week while her medications are adjusted. Doctors expect her to return home to Alabama in three months. If the pig kidney were to fail, she could begin dialysis again. 

“To see hope restored to her and her family is extraordinary,” said Dr. Jayme Locke, Looney’s original surgeon who secured Food and Drug Administration permission for the Nov. 25 transplant. 

More than 100,000 people are on the U.S. transplant list, most who need a kidney. Thousands die waiting and many more who need a transplant never qualify. Now, searching for an alternate supply, scientists are genetically altering pigs so their organs are more humanlike. 

Looney donated a kidney to her mother in 1999. Later a complication during pregnancy caused high blood pressure that damaged her remaining kidney, which eventually failed. It’s incredibly rare for living donors to develop kidney failure although those who do are given extra priority on the transplant list. 

But Looney couldn’t get a match — she had developed antibodies abnormally primed to attack another human kidney. Tests showed she’d reject every kidney donors have offered. 

Then Looney heard about pig kidney research at the University of Alabama at Birmingham and told Locke, at the time a UAB transplant surgeon, she’d like to try one. In April 2023, Locke filed an FDA application seeking an emergency experiment, under rules for people like Looney who are out of options. 

The FDA didn’t agree right away. Instead, the world’s first gene-edited pig kidney transplants went to two sicker patients last spring, at Massachusetts General Hospital and NYU. Both also had serious heart disease. The Boston patient recovered enough to spend about a month at home before dying of sudden cardiac arrest deemed unrelated to the pig kidney. NYU’s patient had heart complications that damaged her pig kidney, forcing its removal, and she later died. 

Those disappointing outcomes didn’t dissuade Looney, who was starting to feel worse on dialysis but, Locke said, hadn’t developed heart disease or other complications. The FDA eventually allowed her transplant at NYU, where Locke collaborated with Montgomery. 

Even if her new organ fails, doctors can learn from it, Looney told the AP: “You don’t know if it’s going to work or not until you try.” 

Blacksburg, Virginia-based Revivicor provided Looney’s new kidney from a pig with 10 gene alterations. Moments after Montgomery sewed it into place, the kidney turned a healthy pink and began producing urine. 

Looney was initially discharged on Dec. 6, wearing monitors to track her blood pressure, heart rate and other bodily functions and returning to the hospital for daily checkups before her medication readmission. Doctors scrutinize her bloodwork and other tests, comparing them to prior research in animals and a few humans in hopes of spotting an early warning if problems crop up. 

“A lot of what we’re seeing, we’re seeing for the first time,” Montgomery said. 

During a visit last week with Locke, who now works for the federal government, Looney hugged her longtime doctor, saying, “Thank you for not giving up on me.” 

“Never,” Locke responded.

Tokyo — Japan wants renewable energy to account for up to 50% of its electricity mix by fiscal year 2040 with nuclear power taking up another 20%, according to a draft of its revised basic energy policy, as it makes a clean energy push while meeting rising power demand.

As the world’s second-largest importer of liquefied natural gas and a major consumer of Middle Eastern oil, Japan and its basic energy plans are drawing global attention from oil, gas and coal producers.

Thermal power usage, particularly from inefficient coal-fired power plants, is set to decrease to between 30% and 40% by 2040 from 68.6% in 2023, although the draft energy policy does not specify the breakdown of coal, gas and oil.

“It is necessary to utilize LNG-fired power as a realistic means of transition, and the government and the private sector must jointly secure the necessary long-term LNG contracts in preparation for risks such as price hikes and supply disruptions,” the draft said.

The industry ministry’s policy draft unveiled on Tuesday proposes increasing renewables to between 40% and 50% of power supplies in the 2040 fiscal year, roughly doubling the 22.9% share in the 2023 fiscal year and exceeding the 2030 target of between 36% and 38%.

Japan’s 2040 nuclear power target is in line with the 2030 target of between 20% and 22%, despite the challenges faced by the industry after the 2011 Fukushima disaster. Nuclear power accounted for 8.5% of the country’s power supply in 2023.

The new energy plan removes the previous target of “reducing reliance on nuclear power as much as possible” and includes plans to build innovative next-generation reactors at nuclear power sites owned by operators who have decided to decommission existing reactors.

Islamabad — Authorities in Pakistan reported Monday that gunmen targeted vaccination teams in northwestern districts during a nationwide campaign against the paralytic poliovirus, resulting in the deaths of at least one health worker and two police officers.

The violence in the militancy-hit Khyber Pakhtunkhwa province, which borders Afghanistan, also injured several polio workers and police force members escorting them. There were no immediate claims of responsibility for the attacks.

Pakistan has reported a significant surge in poliovirus infections in 2024, confirming 63 cases so far, compared to only six cases in 2023.

On Monday, the country launched a weeklong house-to-house vaccination campaign, culminating the year’s anti-polio efforts. Officials said the campaign aims to inoculate more than 44 million children under five to protect them against polio.

Ayesha Raza Farooq, the prime minister’s adviser for the polio eradication program, emphasized parental cooperation to help achieve a polio-free Pakistan.

“We strongly encourage all parents to welcome our dedicated polio workers when they visit your residence and ensure that your children under the age of five receive the necessary two doses of the polio vaccine,” she said.

The World Health Organization lists Pakistan and Afghanistan as the only two countries where the potentially fatal poliovirus continues to cripple children.

WHO officials have cited multiple factors for the resurgence of polio cases in Pakistan. They noted that false propaganda that anti-polio campaigns are a Western plot to sterilize Muslim children has led to vaccine boycotts in some Pakistani districts.

Additionally, insurgents in violence-hit regions occasionally stage deadly attacks on polio teams, suspecting them of spying for the Pakistani security forces, routinely disrupting vaccination drives.

“There are concerning numbers of missed children during the recent campaigns (ranging from 5,000 to 700,000) due to insecurity, boycotts, and program quality issues,” the WHO reported in a statement in August after an emergency committee meeting under the International Health Regulations.

Pakistani authorities have reported the killings of more than 200 polio workers and police personnel escorting them since the country launched vaccination campaigns in the 1990s to control infections.

WHO and officials in Afghanistan have reported at least 23 polio cases in 2024, up from six last year.

In September, the de facto Taliban government abruptly banned the house-to-house vaccination campaign in parts of the war-torn country, permitting only site-to-site and mosque-to-mosque vaccinations of Afghan children.

The WHO committee meeting lamented in its December 3 statement that the Taliban’s ban dealt a setback to the “very encouraging progress” made in Afghanistan during the first half of 2024.

“The committee was concerned about this recent development since site-to-site campaigns are not able to reach all the children in Afghanistan, especially those of younger age and girls,” said the statement. It warned that the restriction poses a substantial risk of a further resurgence of paralytic poliovirus in Afghanistan and beyond.

VIENNA — Three years ago, Andrea Vanek was studying to be an arts and crafts teacher when spells of dizziness and heart palpitations suddenly started to make it impossible for her to even take short walks.

After seeing a succession of doctors she was diagnosed with long COVID and even now spends most of her days in the small living room of her third-floor Vienna apartment, sitting on the windowsill to observe the world outside.

“I can’t plan anything because I just don’t know how long this illness will last,” the 33-year-old Austrian told AFP.

The first cases of COVID-19 were detected in China in December 2019, sparking a global pandemic and more than seven million reported deaths to date, according to the World Health Organization.

But millions more have been affected by long COVID, in which some people struggle to recover from the acute phase of COVID-19, suffering symptoms including tiredness, brain fog and shortness of breath.

Vanek tries to be careful not to exert herself to avoid another “crash”, which for her is marked by debilitating muscle weakness and can last for months, making it hard to even open a bottle of water.

“We know that long COVID is a big problem,” said Anita Jain, from the WHO’s Health Emergencies Programme.

About six percent of people infected by coronavirus develop long COVID, according to the global health body, which has recorded some 777 million COVID cases to date.

Whereas the rates of long COVID after an initial infection are declining, reinfection increases the risk, Jain added.

‘Everything hurts’

Chantal Britt, who lives in Bern, Switzerland, contracted COVID in March 2020. Long COVID, she said, has turned her “life upside down” and forced her to “reinvent” herself. 

“I was really an early bird…. Now I take two hours to get up in the morning at least because everything hurts,” the 56-year-old former marathon runner explained.

“I’m not even hoping anymore that I’m well in the morning but I’m still kind of surprised how old and how broken I feel.”

About 15 percent of those who have long COVID have persistent symptoms for more than one year, according to the WHO, while women tend to have a higher risk than men of developing the condition.

Britt, who says she used to be a “workaholic”, now works part-time as a university researcher on long COVID and other topics. 

She lost her job in communications in 2022 after she asked to reduce her work hours.

She misses doing sports, which used to be like “therapy” for her, and now has to plan her daily activities more, such as thinking of places where she can sit down and rest when she goes shopping.

A lack of understanding by those around her also make it more difficult.

“It’s an invisible disease…. which connects to all the stigma surrounding it,” she said.

“Even the people who are really severely affected, who are at home, in a dark room, who can’t be touched anymore, any noise will drive them into a crash, they don’t look sick,” she said.

Fall ‘through the cracks’

The WHO’s Jain said it can be difficult for healthcare providers to give a diagnosis and wider recognition of the condition is crucial.

More than 200 symptoms have been listed alongside common ones such as fatigue, shortness of breath and cognitive dysfunction.

“Now a lot of the focus is on helping patients, helping clinicians with the tools to accurately diagnose long COVID, detect it early,” she said.

Patients like Vanek also struggle financially. She has filed two court cases to get more support but both are yet to be heard.

She said the less than $840 she gets in support cannot cover her expenses, which include high medical bills for the host of pills she needs to keep her symptoms in check.

“It’s very difficult for students who get long COVID. We fall right through the cracks” of the social system, unable to start working, she said.

Britt also wants more targeted research into post-infectious conditions like long COVID.

“We have to understand them better because there will be another pandemic and we will be as clueless as ever,” she said.

A large number of mysterious drones have been reported flying over parts of New Jersey and the East Coast in recent weeks, sparking speculation and concern over who sent them and why.

New Jersey Gov. Phil Murphy wrote to President Joe Biden asking for answers. New Jersey’s new senator, Andy Kim, spent Thursday night on a drone hunt in rural northern New Jersey, and posted about it on X.

Murphy and law enforcement officials have stressed that the drones don’t appear to be a threat to public safety, but many state and municipal lawmakers have nonetheless called for stricter rules about who can fly the unmanned aircraft.

The FBI is among several agencies investigating and has asked residents to share videos, photos and other information they may have about the drones.

What’s the deal with the drones in New Jersey?

Dozens of witnesses have reported seeing them in the state starting in November.

At first they were spotted flying along the scenic Raritan River, which feeds the Round Valley Reservoir, the state’s largest aquifer, about 50 miles (80 kilometers) west of New York City.

But soon sightings were reported statewide, including near the Picatinny Arsenal, a military research and manufacturing facility, and over President-elect Donald Trump’s golf course in Bedminster.

The aircraft have also recently been spotted in coastal areas.

Republican U.S. Rep. Chris Smith said a Coast Guard commanding officer told him a dozen drones closely followed a Guard lifeboat near Barnegat Light and Island Beach State Park in Ocean County over the weekend.

Federal officials offer assurances that drones don’t pose a threat

The growing anxiety among some residents is not lost on the Biden administration, which has faced criticism from Trump for not dealing with the matter more aggressively.

In a call with reporters Saturday that was organized by the White House, senior officials from the FBI, Pentagon, FAA and other agencies sought to assure people that the drones are not a national security or public safety threat or the handywork of a malicious foreign actor.

An FBI official, who spoke on condition of anonymity under ground rules set by the White House, said the public concern is understandable but added, “I think there has been a slight overreaction.”

Pentagon spokesperson Maj. Gen. Pat Ryder said Thursday that the military’s initial assessment after consulting with the Department of Homeland Security and the National Security Council — that the drones are not of foreign origin — remained unchanged.

New Jersey congressman wants the military to take action

A New Jersey congressman has urged the Pentagon to authorize the use of force to bring down one or more drones to try to figure out who deployed them.

The objects could be downed over the ocean or in an unpopulated area on land, Smith said Saturday at a news conference.

“Why can’t we bag at least one of these drones and get to the bottom of it?” Smith said.

Rep. Jeff Van Drew, another Republican Jersey Shore-area congressman, has also called for the military to shoot down the drones.

Monmouth County Sheriff Shaun Golden said people should not take it into their own hands to shoot down drones, which would break state and federal laws.

Drones have been spotted over New York City

Drone sightings have now been reported in New York, where a permit is required, and Mayor Eric Adams said the city was investigating and collaborating with New Jersey and federal officials.

The runways at Stewart International Airport — about 60 miles (100 kilometers) north of the city — were shut down for about one hour Friday night because of drone activity in the airspace, Gov. Kathy Hochul said.

“This has gone too far,” she said in a statement.

The governor called on Congress to strengthen the FAA’s oversight of drones and give more investigative authority to state and local law enforcement.

“Extending these powers to New York State and our peers is essential,” she said. “Until those powers are granted to state and local officials, the Biden administration must step in by directing additional federal law enforcement to New York and the surrounding region to ensure the safety of our critical infrastructure and our people.”

Are these drones dangerous?

The White House has said that a review of the reported sightings shows that many of them are actually manned aircraft being flown lawfully, echoing the opinion of officials and drone experts.

The federal Homeland Security Department and FBI also said in a joint statement they have no evidence that the sightings pose “a national security or public safety threat or have a foreign nexus.”

Assemblywoman Dawn Fantasia, who was briefed by the Department of Homeland Security, said the reported drones have been up to 6 feet (1.8 meters) in diameter and sometimes travel with their lights switched off. This is much larger than those typically flown by drone hobbyists, and she said they appear to avoid detection by traditional methods such as helicopter and radio.

Who sent the drones?

Authorities say they do not know.

The FBI, Homeland Security and state police are investigating the sightings. Authorities say they don’t know if it is one drone that has been spotted many times or if there are multiple aircraft being flown in a coordinated effort.

Speculation has raged online, with some expressing concerns that the drone or drones could be part of a nefarious plot by foreign agents.

Officials stress that ongoing state and federal investigations have found no evidence to support those concerns, but Rep. Smith on Saturday echoed such speculation.

“The elusive maneuvering of these drones suggests a major military power sophistication that begs the question whether they have been deployed to test our defense capabilities — or worse — by violent dictatorships, perhaps maybe Russia, or China, or Iran, or North Korea,” he said.

Pentagon spokeswoman Sabrina Singh said Wednesday that the aircraft are not U.S. military drones.

What have officials said about the sightings?

Trump has said he believes the government knows more than it’s saying. “Let the public know, and now. Otherwise, shoot them down!!!” he posted on his social media site.

Sen. Richard Blumenthal of Connecticut said Thursday that the drones should be “shot down, if necessary.”

“We should be doing some very urgent intelligence analysis and take them out of the skies, especially if they’re flying over airports or military bases,” Blumenthal said.

Experts, however, warn not to shoot at anything in the sky.

Trisha Bushey, 48, of Lebanon Township, New Jersey, lives near Round Valley Reservoir where there have been numerous sightings and said she doesn’t believe the assertion that the drones aren’t a risk to public safety.

“How can you say it’s not posing a threat if you don’t know what it is?” she said. “I think that’s why so many people are uneasy.”

Are drones allowed in New Jersey?

The flying of drones for recreational and commercial use is legal in the state, but it is subject to local and Federal Aviation Administration regulations and flight restrictions.

In New York City, a permit is required to take off or land an unmanned aircraft.

Operators must be FAA-certified.

Have drones been spotted anywhere else?

Sightings also have been reported in Virginia and elsewhere.

Two people said they spotted an aircraft Thursday night near Virginia Beach that was unlike any other they’ve seen.

The object was over the ocean, and they watched as it slowly moved over an Army National Guard facility, John Knight told The Virginian-Pilot.

“It was definitely different,” said Knight, who took videos of what he thinks was a drone the size of a small truck.

“It flew like a helicopter but made no noise,” he added.

The Virginia National Guard did not have any aircraft operating in the area Thursday night, according to spokesperson A.A. “Cotton” Puryear. Its leadership is aware of the incident and it’s under investigation.

Another military installation in the area is Naval Air Station Oceana Dam Neck Annex. NAS Oceana, the East Coast master jet base in Virginia Beach, is aware of recent reports of sightings in the area and is coordinating with federal and state agencies to ensure the safety of its personnel and operations, Katie Hewett, public affairs officer, said Friday by email.

Knight submitted the videos Thursday night to the FBI tip line.

In Massachusetts, 10 to 15 drones were reported hovering over a home Thursday night in Harwich on Cape Cod. A resident told police they were bright and she observed them for more than an hour.

Earlier that evening, an off-duty police officer in the same town noticed similar activity near a public safety complex, police said. The information was forwarded to the FBI and Massachusetts State Police.

Drones were also spotted last month in the U.K. The U.S. Air Force said several small unmanned aircraft were detected near four military bases in England that are used by American forces.
