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.

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.”

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.
