Chinese authorities are cracking down on political and fraud cases driven by deepfakes, created with face- and voice-changing software that tricks targets into believing they are video chatting with a loved one or another trusted person.

How good are the deepfakes? Good enough to trick an executive at a Fuzhou tech company in Fujian province who almost lost $600,000 to a person he thought was a friend claiming to need a quick cash infusion.

The entire transaction took less than 10 minutes from the first contact via the phone app WeChat to police stopping the online bank transfer when the target called the authorities after learning his real friend had never requested the loan, according to Sina Technology.

Despite the public’s outcry about such AI-driven fraud, some experts say Beijing appears more concerned about the political challenges that deepfakes may pose, as shown by newly implemented regulations on “deep synthesis” management that outlaw activities that “endanger national security and interests and damage the national image.”

The rapid development of artificial intelligence technology has propelled cutting-edge technology to mass entertainment applications in just a few years.

In a 2017 demonstration of the risks, a video created by University of Washington researchers showed then-U.S. President Barack Obama saying things he hadn’t.

Two years later, Chinese smartphone apps like Zao let users swap their faces with celebrities so they could appear as if they were in a movie. Zao was removed from app stores in 2019 and Avatarify, another popular Chinese face-swapping app, was also banned in 2021, likely for violation of privacy and portrait rights, according to Chinese media.

Pavel Goldman-Kalaydin, head of artificial intelligence and machine learning at SumSub, a Berlin-based global antifraud company, explained how easy it is with a personal computer or smartphone to make a video in which a person appears to say things he or she never would.

“To create a deepfake, a fraudster uses a real person’s document, taking a photo of it and turning it into a 3D persona,” he said. “The problem is that the technology, it is becoming more and more democratized. Many people can use it. … They can create many deepfakes, and they try to bypass these checks that we try to enforce.”

Subbarao Kambhampati, professor at the School of Computing and Augmented Intelligence at Arizona State University, said in a telephone interview he was surprised by the apparent shift from voice cloning to deepfake video calling by scammers in China. He compared that to a rise in voice-cloning phone scams in the U.S.

“Audio alone, you’re more easily fooled, but audio plus video, it would be little harder to fool you. But apparently they’re able to do it,” Kambhampati said, adding that it is harder to make a video that appears trustworthy.

“Subconsciously we look at people’s faces … and realize that they’re not exactly behaving the way we normally see them behave in terms of their facial expressions.”

Experts say that AI fraud will become more sophisticated.

“We don’t expect the problem to go away. The biggest solution … is education, let people understand the days of trusting your ears and eyes are over, and you need to keep that in the back of your mind,” Kambhampati said.

The Internet Society of China issued a warning in May, calling on the public to be more vigilant as AI face-changing, voice-changing scams and slanders became common.

The Wall Street Journal reported on June 4 that local governments across China have begun to crack down on false information generated by artificial intelligence chatbots. Much of the false content designed as clickbait is similar to authentic material on topics that have already attracted public attention.

To regulate “deep synthesis” content, China’s administrative measures implemented on January 10 require service providers to “conspicuously mark” AI-generated content that “may cause public confusion or misidentification” so that users can tell authentic media content from deepfakes.

China’s practice of requiring technology platforms to “watermark” deepfake content has been widely discussed internationally.

Matt Sheehan, a fellow in the Asia Program at the Carnegie Endowment for International Peace, noted that deepfake regulations place the onus on the companies that develop and operate these technologies.

“If enforced well, the regulations could make it harder for criminals to get their hands on these AI tools,” he said in an email to VOA Mandarin. “It could throw up some hurdles to this kind of fraud.”

But he also said that much depends on how Beijing implements the regulations and whether bad actors can obtain AI tools outside China.

“So, it’s not a problem with the technology,” said SumSub’s Goldman-Kalaydin. “It is always a problem with the usage of the technology. So, you can regulate the usage, but not the technology.”

James Lewis, senior vice president of the strategic technologies program at the Center for Strategic and International Studies in Washington, told VOA Mandarin, “Chinese law needs to be modernized for changes in technology, and I know the Chinese are thinking about that. So, the cybercrime laws you have will probably catch things like deepfakes. What will be hard to handle is the volume and the sophistication of the new products, but I know the Chinese government is very worried about fraud and looking for ways to get control of it.”

Others suggest that in regulating AI, political stability is a bigger concern for the Chinese government.

“I think they have a stronger incentive to work on the political threats than they do for fraud,” said Bill Drexel, an associate fellow for the Technology and National Security Program at Center for a New American Security.

In May, the hashtag #AIFraudEruptingAcrossChina was trending on China’s social media platform Weibo. However, the hashtag has since been censored, according to the Wall Street Journal, suggesting authorities are discouraging discussion on AI-driven fraud.

“So even we can see from this incident, once it appeared that the Chinese public was afraid that there was too much AI-powered fraud, they censored,” Drexel told VOA Mandarin.

He continued, “The fact that official state-run media initially reported these incidents and then later discussion of it was censored just goes to show that they do ultimately care about covering themselves politically more than they care about addressing fraud.”

The long hunt for extraterrestrials just got a big boost.

Scientists have discovered that phosphorus, a key building block of life, lies in the ocean beneath the icy surface of Saturn’s moon Enceladus.

The finding was based on a review of data collected by NASA’s Cassini probe, and it was published Wednesday in the prestigious journal Nature.

Cassini started exploring Saturn and its rings and moons in 2004, before burning up in the gas giant’s atmosphere when its mission ended in 2017.

“This is a stunning discovery for astrobiology,” said Christopher Glein of the Southwest Research Institute, one of the paper’s co-authors, noting: “We have found abundant phosphorus in plume ice samples spraying out of the subsurface ocean.”

Geysers on Enceladus’ south pole spew icy particles through cracks on the surface out into space, feeding Saturn’s E ring — the faint ring outside the brighter main rings. 

Scientists previously found other minerals and organic compounds in the ejected ice grains, but not phosphorus, which is an essential building block for DNA and RNA. It also is found in the bones and teeth of people, animals, and even ocean plankton.

Simply put, life as we know it would not be possible without phosphorus.

While geochemical modeling had previously found it was likely phosphorus would also be present, and this prediction was published in an earlier paper, it is one thing to forecast something and another to confirm, said Glein.

“It’s the first time this essential element has been discovered in an ocean beyond Earth,” added first author Frank Postberg, a planetary scientist at Freie Universitat Berlin, in a NASA statement.

To make the new discovery, authors combed through data collected by Cassini’s Cosmic Dust Analyzer instrument, and confirmed the findings by carrying out laboratory experiments to show that Enceladus’ ocean has phosphorus bound inside different water-soluble forms.  

Over the past 25 years, planetary scientists have discovered that worlds with oceans beneath a surface layer of ice are common in our solar system.

These include Jupiter’s moon Europa, Saturn’s largest moon Titan, but even the more distant body, Pluto.

While planets like Earth that have surface oceans need to reside within a narrow window of distance from their host star to maintain the right temperatures for life, the discovery of worlds with subsurface oceans expands the number of habitable bodies that might exist.  

“With this finding, the ocean of Enceladus is now known to satisfy what is generally considered to be the strictest requirement for life,” said Glein.

“The next step is clear — we need to go back to Enceladus to see if the habitable ocean is actually inhabited.”

Bill Gates, Microsoft Corp’s co-founder, is set to meet Chinese President Xi Jinping on Friday during his visit to China, two people with knowledge of the matter said.

The meeting will mark Xi’s first meeting with a foreign private entrepreneur in recent years. The people said the encounter may be a one-on-one meeting. A third source confirmed they would meet, without providing details.

The sources did not say what the two might discuss. Gates tweeted on Wednesday that he had landed in Beijing for the first time since 2019 and that he would meet with partners who had been working on global health and development challenges with the Bill & Melinda Gates Foundation.

The foundation and China’s State Council Information Office, which handles media queries on behalf of the Chinese government, did not immediately respond to Reuters requests for comment. 

Gates stepped down from Microsoft’s board in 2020 to focus on philanthropic works related to global health, education and climate change. He quit his full-time executive role at Microsoft in 2008. 

The last reported meeting between Xi and Gates was in 2015, when they met on the sidelines of the Boao forum in Hainan province. In early 2020, Xi wrote a letter to Gates thanking him, and the Bill & Melinda Gates Foundation, for pledging assistance to China including $5 million for its fight against COVID. 

The meeting would mark the end of a long hiatus by Xi in recent years from meeting foreign private entrepreneurs and business leaders, after the Chinese president stopped traveling abroad for nearly three years as China shut its borders during the pandemic. 

Several foreign CEOs have visited China since it reopened early this year but most have mainly met with government ministers. 

Premier Li Qiang met a group of CEOs including Apple’s Tim Cook in March and a source told Reuters that Tesla’s Elon Musk met vice-premier Ding Xuexiang last month.

EU lawmakers on Wednesday voted for tougher landmark draft artificial intelligence rules that include a ban on the use of the technology in biometric surveillance and for generative AI systems like ChatGPT to disclose AI-generated content.

The lawmakers agreed to the amendments to the draft legislation proposed by the European Commission which is seeking to set a global standard for the technology used in everything from automated factories to bots and self-driving cars.

Rapid adoption of Microsoft-backed OpenAI’s ChatGPT and other bots has led top AI scientists and company executives including Elon Musk and OpenAI CEO Sam Altman to raise the potential risks posed to society.

“While Big Tech companies are sounding the alarm over their own creations, Europe has gone ahead and proposed a concrete response to the risks AI is starting to pose,” said Brando Benifei, co-rapporteur of the draft act.

Among other changes, European Union lawmakers want any company using generative tools to disclose copyrighted material used to train its systems and for companies working on “high-risk application” to do a fundamental rights impact assessment and evaluate environmental impact.

Microsoft, which has called for AI rules, welcomed the lawmakers’ agreement.

“We believe that AI requires legislative guardrails, alignment efforts at an international level, and meaningful voluntary actions by companies that develop and deploy AI,” a Microsoft spokesperson said.

However, the Computer and Communications Industry Association said the amendments on high-risk AIs were likely to overburden European AI developers with “excessively prescriptive rules” and slow down innovation.

“AI raises a lot of questions – socially, ethically, economically. But now is not the time to hit any ‘pause button’. On the contrary, it is about acting fast and taking responsibility,” EU industry chief Thierry Breton said.

The Commission announced its draft rules two years ago aimed at setting a global standard for a technology key to almost every industry and business and in a bid to catch up with AI leaders the United States and China.

The lawmakers will now have to thrash out details with European Union countries before the draft rules become legislation.

Six percent of all maternal deaths around the world are caused by obstructed labor, according to the World Health Organization. That’s when a baby can’t move through the birth canal. It can also lead to obstetric fistula, a condition that can have a long-term impact on a woman’s health, especially in developing countries.

European Union antitrust regulators took aim at Google’s lucrative digital advertising business in an unprecedented decision ordering the tech giant to sell off some of its ad business to address competition concerns.

The European Commission, the bloc’s executive branch and top antitrust enforcer, said that its preliminary view after an investigation is that “only the mandatory divestment by Google of part of its services” would satisfy the concerns.

The 27-nation EU has led the global movement to crack down on Big Tech companies, but it has previously relied on issuing blockbuster fines, including three antitrust penalties for Google worth billions of dollars.

It’s the first time the bloc has ordered a tech giant to split up keys of business.

Google can now defend itself by making its case before the commission issues its final decision. The company didn’t immediately respond to a request for comment.

The commission’s decision stems from a formal investigation that it opened in June 2021, looking into whether Google violated the bloc’s competition rules by favoring its own online display advertising technology services at the expense of rival publishers, advertisers and advertising technology services.

YouTube was one focus of the commission’s investigation, which looked into whether Google was using the video sharing site’s dominant position to favor its own ad-buying services by imposing restrictions on rivals.

Google’s ad tech business is also under investigation by Britain’s antitrust watchdog and faces litigation in the U.S.

Brussels has previously hit Google with more than $8.6 billion worth of fines in three separate antitrust cases, involving its Android mobile operating system and shopping and search advertising services.

The company is appealing all three penalties. An EU court last year slightly reduced the Android penalty to 4.125 million euros. EU regulators have the power to impose penalties worth up to 10% of a company’s annual revenue.

When peanuts are dropped into a pint of beer, they sink to the bottom before floating up and “dancing” in the glass. 

Scientists have dug deep to investigate this phenomenon in a study published on Wednesday, saying it has implications for understanding mineral extraction or bubbling magma in the Earth’s crust. 

Brazilian researcher Luiz Pereira, the study’s lead author, told AFP he first had the idea when passing through Argentina’s capital Buenos Aires to learn Spanish.  

It was a “bartender thing” in the city to take a few peanuts and pop them into beers, Pereira said. 

Because the peanuts are denser than the beer, they first sink down to the bottom of the glass. 

Then each peanut becomes what is called a “nucleation site.” Hundreds of tiny bubbles of carbon dioxide form on their surface, acting as buoys to drag them upward. 

“The bubbles prefer to form on the peanuts rather than on the glass walls,” said Pereira, a researcher at Germany’s Ludwig Maximilian University of Munich. 

When the bubbles reach the surface, they burst. 

The peanuts sink again before being propelled up anew by freshly formed bubbles, in a dance that continues until the carbon dioxide runs out, or someone interrupts it by drinking the beer. 

In a series of experiments, the team of researchers in Germany, Britain and France examined how roasted, shelled peanuts fared in a lager-style beer. 

‘Beer-gas-peanut system’

The study, published in the journal Royal Society Open Science, describes two key factors in what the researchers dubbed the “beer-gas-peanut system.” 

They found that the larger the “contact angle” between the curve of an individual bubble and the surface of the peanut was, the more likely it was to form and grow.  

But it cannot grow too much — a radius of less than 1.3 millimeters is ideal, the study said. 

Pereira said he hoped that “by deeply researching this simple system, which everyone can grasp, we can understand a system” that would be useful for industry or explaining natural phenomena. 

For example, he said the floatation process was similar to the one used to separate iron from ore. 

Air is injected, in a controlled way, into a mixture in which a mineral, such as iron, “will rise because bubbles attach themselves more easily to it, while other (minerals) sink to the bottom,” he said. 

The same process could also explain why volcanologists find that the mineral magnetite rises to higher layers in the crystalized magma of the Earth’s crust than would be expected. 

Like peanuts, magnetite is denser, so should sit at the bottom. But because of a high contact angle, the researchers theorize, the mineral rises through the magma with help from gas bubbles. 

Of course, science is never settled, particularly when beer is involved. 

Hoping to create a better model of the dancing peanut phenomenon, Pereira said the scientists will continue to “play with the characteristics of different peanuts and different beers.”
