Washington — Researchers at Michigan State University recently discovered that honeybees, with their keen sense of smell, can sniff out lung cancer on a patient’s breath.

“Our world is visual. Insects’ world is all based on smell, so their sense of smell is very, very good,” says Debajit Saha, assistant professor of biomedical engineering at Michigan State University, who was part of a team that published research on the discovery last month.

“There is quite a bit of research that shows that when some cancer grows inside our body, our breath actually changes. Our research does show that honeybees can detect lung cancer and possibly other diseases based on the smell of those cells.”

Saha and his team harnessed the bees and attached electrodes to their brains. The insects were then exposed to synthetic compounds that mimicked the breath of a lung cancer patient. Ninety-three percent of the time, the bees could tell the difference between the cancer breath and the artificial breath of a healthy person. The bees could also distinguish between different types of lung cancer.

The discovery could have implications for early detection of many cancers, including lung, breast, head and neck, and colorectal cancers.

“We do think breath-based diagnostics of cancer can be a game changer,” Saha says. “The reason is, many times we detect the cancer late, when the tumor has already grown pretty big. But generally, when cancer starts growing in your body, the breath signature starts changing much earlier.”

He hopes to develop a portable system in which electrodes are implanted in a honeybee brain that a patient will be able to breathe into. This cyborg sensor, which is part-brain, part-engineered, would deliver test results in real time.

“Hopefully, within the next five years, we’ll have something to show that humans can be diagnosed using these insect brain disc sensors,” Saha says.

Using animals to detect cancer isn’t a new concept. At the Penn Vet Working Dog Center at the University of Pennsylvania, researchers are training dogs to recognize certain cancer odors.

“A lot of other animals also have quite intense and capable senses of smell,” says Cindy Otto, executive director of the Penn Vet Working Dog Center. “But part of what makes dogs so good is that they cooperate with humans, and so, they communicate that information.”

The dogs are in a foster program where they live with families and are brought to “work” each day. Not all dogs can do the work, according to Clara Wilson, a postdoctoral researcher at the center.

“If the dog is not really interested in this type of work, we find out pretty quickly. And you can’t make a dog want to do this, because they’re not going to give you high-quality answers,” Wilson says. “They need to love it to be engaged. And so, it’s a really fun game for them.”

Sniffing out cancer might be a game to the animals, but researchers are finding that the animals detect cancer better than machines. A dog’s sense of smell is 10,000 to 100,000 times more acute than that of humans.

“Why are we finding that these dogs are outperforming the computers?” says Amritha Mallikarjun, another postdoctoral researcher at the center. “Well, part of their success is because of this superior sensitivity to detect odor molecules as compared to anything we currently have on the market.”

The researchers hope to continue isolating characteristics of cancer odors to enhance technological development, eventually creating e-noses that duplicate a dog’s cancer sniffing abilities, enabling earlier detection of cancer.

“This may not be the endgame, but I think it’s going to advance the overall approach to diagnosing not only cancer but many other diseases,” Otto says.

“You can look back in history to the Greeks and Romans. The physicians then used odor as part of their diagnostic tools, and I think as modern humans, we’ve kind of let go of that. I think we can really capitalize on that and advance the health of not only humans, but dogs and other species as well.”

Canada announced Wednesday it won’t block access to the popular video-sharing app TikTok but is ordering the dissolution of its Canadian business after a national security review of the Chinese company behind it.

Industry Minister François-Philippe Champagne said it is meant to address risks related to ByteDance Ltd.’s establishment of TikTok Technology Canada Inc.

“The government is not blocking Canadians’ access to the TikTok application or their ability to create content. The decision to use a social media application or platform is a personal choice,” Champagne said.

Champagne said it is important for Canadians to adopt good cybersecurity practices, including protecting their personal information.

He said the dissolution order was made in accordance with the Investment Canada Act, which allows for the review of foreign investments that may harm Canada’s national security. He said the decision was based on information and evidence collected over the course of the review and on the advice of Canada’s security and intelligence community and other government partners.

A TikTok spokesperson said in a statement that the shutdown of its Canadian offices will mean the loss of hundreds of local jobs.

“We will challenge this order in court,” the spokesperson said. “The TikTok platform will remain available for creators to find an audience, explore new interests and for businesses to thrive.”

TikTok is wildly popular with young people, but its Chinese ownership has raised fears that Beijing could use it to collect data on Western users or push pro-China narratives and misinformation. TikTok is owned by ByteDance, a Chinese company that moved its headquarters to Singapore in 2020.

TikTok faces intensifying scrutiny from Europe and America over security and data privacy. It comes as China and the West are locked in a wider tug of war over technology ranging from spy balloons to computer chips.

Canada previously banned TikTok from all government-issued mobile devices. TikTok has two offices in Canada, one in Toronto and one in Vancouver.

Michael Geist, Canada research chair in Internet and E-commerce Law at the University of Ottawa, said in a blog post that “banning the company rather than the app may actually make matters worse since the risks associated with the app will remain but the ability to hold the company accountable will be weakened.”

Canada’s move comes a day after the election in the United States of Donald Trump. In June, Trump joined TikTok, a platform he once tried to ban while in the White House. It has about 170 million users in the U.S.

Trump tried to ban TikTok through an executive order that said “the spread in the United States of mobile applications developed and owned” by Chinese companies was a national security threat. The courts blocked the action after TikTok sued.

Both the U.S. FBI and the Federal Communications Commission have warned that ByteDance could share user data such as browsing history, location and biometric identifiers with China’s government. TikTok said it has never done that and would not, if asked.

Trump said earlier this year that he still believes TikTok posed a national security risk, but was opposed to banning it.

U.S. President Joe Biden signed legislation in April that would force ByteDance to sell the app to a U.S. company within a year or face a national ban. It’s not clear whether that law will survive a legal challenge filed by TikTok or that ByteDance would agree to sell.

sydney — The Australian government will legislate for a ban on social media for children under 16, Prime Minister Anthony Albanese said on Thursday, in what it calls a world-leading package of measures that could become law late next year.

Australia is trying out an age-verification system to assist in blocking children from accessing social media platforms, as part of a range of measures that include some of the toughest controls imposed by any country to date.

“Social media is doing harm to our kids and I’m calling time on it,” Albanese told a news conference.

Albanese cited the risks to physical and mental health of children from excessive social media use, in particular the risks to girls from harmful depictions of body image, and misogynist content aimed at boys.

“If you’re a 14-year-old kid getting this stuff, at a time where you’re going through life’s changes and maturing, it can be a really difficult time, and what we’re doing is listening and then acting,” he said.

A number of countries have already vowed to curb social media use by children through legislation, though Australia’s policy is one of the most stringent.

No jurisdiction so far has tried using age verification methods like biometrics or government identification to enforce a social media age cut-off, two of the methods being tried.

Australia’s other world-first proposals are the highest age limit set by any country, no exemption for parental consent and no exemption for pre-existing accounts.

Legislation will be introduced into the Australian parliament this year, with the laws coming into effect 12 months after being ratified by lawmakers, Albanese said.

The opposition Liberal Party has expressed support for a ban.

“The onus will be on social media platforms to demonstrate they are taking reasonable steps to prevent access,” Albanese said. “The onus won’t be on parents or young people.”

“What we are announcing here and what we will legislate will be truly world-leading,” Communications Minister Michelle Rowland said.

Rowland said platforms impacted would include Meta Platforms’ Instagram and Facebook, as well as Bytedance’s TikTok and Elon Musk’s X. Alphabet’s YouTube would likely also fall within the scope of the legislation, she added.

TikTok declined to comment, while Meta, Alphabet and X did not respond to requests for comment.

The Digital Industry Group, a representative body that includes Meta, TikTok, X and Alphabet’s Google as members, said the measure could encourage young people to explore darker, unregulated parts of the internet while cutting their access to support networks.

“Keeping young people safe online is a top priority … but the proposed ban for teenagers to access digital platforms is a 20th Century response to 21st Century challenges,” said DIGI Managing Director Sunita Bose.

“Rather than blocking access through bans, we need to take a balanced approach to create age-appropriate spaces, build digital literacy and protect young people from online harm,” she added.

France last year proposed a ban on social media for those under 15, though users were able to avoid the ban with parental consent.

The United States has for decades required technology companies to seek parental consent to access the data of children under 13, leading to most social media platforms banning those under that age from accessing their services.

PARIS — Seven French families have filed a lawsuit against social media giant TikTok, accusing the platform of exposing their adolescent children to harmful content that led to two of them taking their own lives at 15, their lawyer said on Monday.

The lawsuit alleges TikTok’s algorithm exposed the seven teenagers to videos promoting suicide, self-harm and eating disorders, lawyer Laure Boutron-Marmion told broadcaster franceinfo.

The families are taking joint legal action in the Créteil judicial court. Boutron-Marmion said it was the first such grouped case in Europe.

“The parents want TikTok’s legal liability to be recognized in court,” she said, adding: “This is a commercial company offering a product to consumers who are, in addition, minors. They must, therefore, answer for the product’s shortcomings.”

TikTok, like other social media platforms, has long faced scrutiny over the policing of content on its app.

As with Meta’s Facebook and Instagram, it faces hundreds of lawsuits in the U.S. accusing them of enticing and addicting millions of children to their platforms, damaging their mental health.

TikTok could not immediately be reached for comment on the allegations.

The company has previously said it took issues that were linked to children’s mental health seriously. CEO Shou Zi Chew this year told U.S. lawmakers the company has invested in measures to protect young people who use the app.

HANOI, Vietnam — U.S. tech companies have warned Vietnam’s government that a draft law to tighten rules on data protection and limit data transfers abroad would hamper social media platforms and data center operators from growing their businesses in the country.

The Southeast Asian nation with a population of 100 million is one of the world’s largest markets for Facebook and other online platforms, and is aiming to exponentially increase its data center industry with foreign investment in coming years.

The draft law “will make it challenging for tech companies, social media platforms and data center operators to reach the customers that rely on them daily,” said Jason Oxman, who chairs the Information Technology Industry Council (ITI), a trade association representing big tech companies including Meta, Google and data centers operator Equinix.

The draft law, being discussed in parliament, is also designed to ease authorities’ access to information and was urged by the ministry of public security, Vietnamese and foreign officials said.

The ministry of public security and the information ministry did not respond to attempts to contact them via email and phone.

Vietnam’s parliament is discussing the law in its current month-long session and is scheduled to pass it on Nov. 30 “if eligible,” according to its program, which is subject to changes.

Existing Vietnamese regulations already limit cross-border transfers of data under some circumstances, but they are rarely enforced.

It is unclear how the new law, if adopted, would impact foreign investment in the country. Reuters reported in August that Google was considering setting up a large data center in southern Vietnam before the draft law was presented in parliament.

Research firm BMI had said Vietnam could become a major regional player in the data center industry as limits on foreign ownership are set to end next year.

Among the provisions of the draft law is prior authorization for the transfer overseas of “core data” and “important data,” which are currently vaguely defined.

“That will hinder foreign business operations,” Oxman told Reuters.

Tech companies and other firms favor cross-border data flows to cut costs and improve services, but multiple jurisdictions, including the European Union and China, have limited those transfers, saying that allows them to better protect privacy and sensitive information.

Under the draft law, companies will have to share data with Vietnam’s ruling Communist Party and state organizations in multiple, vaguely defined cases including for “fulfilling a specific task in the public interest.”

The U.S. tech industry has raised concerns with Vietnamese authorities over “the undue expansion of government access to data,” Oxman said.

The new law “would cause significant compliance challenges for most private sector companies,” said Adam Sitkoff, executive director of the American Chamber of Commerce in Hanoi, noting talks were underway to persuade authorities to “reconsider the rushed legislative process” for the law.

ADAMA, ETHIOPIA — Residents in Ethiopia’s Oromia region say access to phone communication and internet service has been disrupted for months as government forces fight against two rebel groups.

The disruption of mobile phone calls and internet data has been concentrated in conflict-hit Oromia zones, where government forces have engaged in fighting against the Oromo Liberation Army, or the OLA.

A resident from South Oromia of Guji Zone Wadera Wereda, who spoke to VOA on condition of anonymity for safety reasons, said phone and internet data connections have been cut in his area due to the fighting.

He said there was fighting on Monday and the week before in Wadera Wereda, where regional security personnel including local police were killed. Other residents confirmed the same clashes without giving specific casualty figures. Local authorities could not be reached for comment.

The data outage and network disruptions were also reported in the North Shewa Zone administration of Oromia region.

“The zone has been under network blockade for the last two months due to the insurgency,” said a second resident from Dera Wereda in North Shewa, who also sought anonymity due to safety reasons.

Residents also said people who lost their SIM cards or want replacements could not do so at local telecom offices because the conflict has affected supplies. Network disruptions also impacted schools in the area that access materials online.

He says his school had to transfer all its grade-12 students this year to neighboring Wereda due to a lack of service.

“We cannot manage to send their details and credentials to relevant bodies,” with the downed service, he told VOA in a phone interview.

Journalists have waited for hours to speak to residents in Kelem Welega Zone, whose network is down during morning hours. One resident traveled to Dembi Dolo, about 620 kilometers west of the capital, Addis Ababa, to speak with the media about the network outages.

The disruptions have been present since the yearslong fighting between federal forces and the OLA began in 2019. In one of the latest deadliest attacks, suspected OLA fighters killed as many as 17 pro-government militiamen in the West Showa zone of Oromia on October 17, according to residents and local officials.

A second rebel group, Fano, is also fighting in the neighboring Amhara region, which spills over on either side.

Residents say as the intensity of the clashes increases, the network situation becomes worse, as the government resorts to shutting down communication.

“It’s a very unfortunate tactic that is usually used by governments that are struggling with legitimacy issues,” said Horn of Africa security analyst Samira Gaid.

“It only serves to convince the masses that the government has something to hide. Rather than controlling the narrative or news reporting, it elevates mistrust in government, adds to misinformation and disinformation, and contributes to groups becoming more covert with their communications,” she told VOA.

Ethiopia’s state-run communication outlets have not responded to repeated VOA requests for comment.

Speaking at a press conference in Addis Ababa last month, Frehiwot Tamiru, CEO of Ethio Telecom, admitted that such problems exist in conflict areas. She declined to give specific answers, referring reporters to other government entities.

In June, the company said it has repaired and restored service to dozens of mobile stations that had previously been damaged in the western region of the country.
