Video of a Chinese paraglider widely published by news media outlets around the world was at least partly manipulated by generative artificial intelligence tools, experts said.
Remarkable footage of 55-year-old paraglider Peng Yujiang, face encrusted with ice after purportedly being sucked into the upper atmosphere, was widely covered by Chinese and international media outlets last week including the ABC.
The video had been sourced from Chinese state media outlet CCTV via Reuters.
Reuters distanced itself from the content in a statement.
"The content is clearly labelled as third-party content and is not verified or endorsed by Reuters," the company said.
"When we became aware of a piece of content that likely contained AI-generated elements on the Reuters Connect platform, we investigated and took it down because the material does not comply with our partner content policy."
The ABC also removed the original story and published an editor's note clarifying that Peng's claim that he was lifted 8598 metres could not be independently verified.
Associate Professor Abhinav Dhall from Monash University's Department of Data Science and AI said there were several factors that meant the video was difficult to identify as manipulated, including the low quality of the footage.
"It's difficult to figure out if it's real or fake," he told the ABC.
"[But] if we closely observe the starting say 3 or 4 seconds of this video we can see that the clouds in the background do not really look real. They look like as if, you know, it's a 2D picture."
Dhall said it was difficult even for experts to detect "subtle manipulations" to images or video.
RMIT generative AI and journalism researcher TJ Thomson agreed.
"It didn't seem overly dodgy or suspicious at first glance especially looking at it on a small smartphone screen with our attention frayed," he said.
"But if you look at it more closely, I think things start to come to the surface. You can pick up little things - the colour of the helmet, for example, changing colour.
"Looks like the colour of cord shifts over time, looks like the ground's visible and then not a few seconds later."
'Generational change' forced by generative AI
It is plausible that Peng did indeed reach the height he claimed, despite the video being doctored.
German paraglider Ewa Wisnierska was sucked nearly 10,000 metres into the air above NSW by a storm front in 2007 and lived to tell the tale.
"It could be that they're splicing together multiple clips of actual real footage or that AI has been used here to generate or edit some content," Dr Thomson said.
Still, he said the case demonstrated the risks of generative AI for shrinking newsrooms, which have become ever-more reliant on crowd-sourced material.
"We see 728,000 hours of video being uploaded online every day and more than three billion images being uploaded online every day," he said.
"It can be helpful to integrate that crowd-sourced footage into our reporting, but it's the scale and speed by which that content travels is really hard for journalists to fact-check."
Australia's journalist union, the Media, Entertainment and Arts Alliance (MEAA), told the ABC it had been calling on the federal government to regulate AI.
"Our members have been telling us that they are concerned about misinformation and disinformation and the potential erosion of public trust in journalism and the media," a spokesperson said.
"That's why we have been calling on government to introduce new AI legislation that will govern the use of generative AI, protect creative works from AI theft and increase transparency."
MEAA chief executive Erin Madeley said last year that use of AI generation would "drive the erosion of our news and information to the point where the community cannot tell fact from fiction".
Monash's Dr Dhall said there was a "big, generational change" happening regarding the creative ways in which users could manipulate data - and that there was a role for both industry and government.
"I reckon it will take some time for systems - automatic systems and human observers - to get on page and quickly realise that something is fake or not," he said.
"But there is hope. There is research going on within academia and industry, developing tools that will be able to identify [AI manipulation], along with a human being."

Nvidia briefly on track to become world's most valuable company ever
By Noel Randewich and Shashwat Chauhan , Reuters The Nvidia logo on a mobile phone, on 31 January, 2025. Photo: AFP/ Beata Zawrzel Nvidia (NVDA.O), opens new tab hit a market value of US$3.92 trillion, briefly putting it on track to become the most valuable company in history, as Wall Street doubled down on optimism about AI. Shares of the leading designer of high-end AI chips rose as much as 2.4 percent to US$160.98 in morning trading, giving the company a higher market capitalization than Apple's (AAPL.O), opens new tab record closing value of US$3.915 trillion on 26 December, 2024. The shares were last up 1.5 percent at $159.60, leaving Nvidia's stock market value at $3.89 trillion, just short of Apple's record. Nvidia's newest chips have made gains in training the largest artificial-intelligence models, fueling demand for products by the Santa Clara, California, company. Microsoft (MSFT.O), opens new tab is currently the second-most valuable company on Wall Street, with a market capitalisation of $3.7 trillion as its shares rose 1.7 percent to $499.56. Apple rose 0.8 percent, giving it a market value of $3.19 trillion, in third place. A race among Microsoft, (AMZN.O), opens new tab, Meta Platforms (META.O), opens new tab, Alphabet (GOOGL.O), opens new tab and Tesla (TSLA.O), opens new tab to build AI data centers and dominate the emerging technology has fueled insatiable demand for Nvidia's high-end processors. "When the first company crossed a trillion dollars, it was amazing. And now you're talking four trillion, which is just incredible. It tells you that there's this huge rush with AI spending and everybody's chasing it right now," said Joe Saluzzi, co-manager of trading at Themis Trading. The stock market value of Nvidia, whose core technology was developed to power video games, has increased nearly eight-fold over the past four years, from $500 billion in 2021 to now near $4 trillion. Nvidia is now worth more than the combined value of the Canadian and Mexican stock markets, according to LSEG data. The tech company also exceeds the total value of all publicly listed companies in the United Kingdom. Nvidia recently traded at about 32 times analysts' expected earnings for the next 12 months, below its average of about 41 over the past five years, according to LSEG data. That relatively modest price-to-earnings valuation reflects steadily increasing earnings estimates that have outpaced Nvidia's sizable stock gains. The company's stock has now rebounded more than 68 percent from its recent closing low on 4 April, when Wall Street was reeling from President Donald Trump's global tariff announcements. US stocks, including Nvidia, have recovered on expectations that the White House will cement trade deals to soften Trump's tariffs. Nvidia's swelling market capitalization underscores Wall Street's big bets on the proliferation of generative AI technology, with the chipmaker's hardware serving as the foundation. The sharp increases in the shares of Nvidia and other Wall Street heavyweights have left people who save for their retirements through widely used S&P 500 index funds heavily exposed to the future of AI technology. Nvidia now accounts for 7 percent of the S&P 500 (.SPX), opens new tab. Nvidia, Microsoft, Apple, Amazon and Alphabet together make up 28 percent of the index. "I strongly believe that AI is a greatly productive tool, but I am fairly sure that the current delivery of AI via large language models and large reasoning models are unlikely to live up to the hype," cautioned Kim Forrest, chief investment officer at Bokeh Capital Partners. Co-founded in 1993 by CEO Jensen Huang, Nvidia has evolved from a niche company popular among video game enthusiasts into Wall Street's barometer for the AI industry. The stock's recent rally comes after a slow first half of the year, when investor optimism about AI took a back seat to worries about tariffs and Trump's trade dispute with Beijing. Chinese startup DeepSeek in January triggered a selloff in global equities markets with a cut-price AI model that outperformed many Western competitors and sparked speculation that companies might spend less on high-end processors. In November of last year, Nvidia took over the spot on the Dow Jones Industrial Average formerly occupied by chipmaker Intel (INTC.O), opens new tab, reflecting a major shift in the semiconductor industry toward AI-linked development and the graphics processing hardware pioneered by Nvidia. - Reuters

The dos and don'ts of applying for a job using AI
By Daniel Johnson , ABC Photo: Thomas Lefebvre / Unsplash Applying for jobs can be stressful and if writing a cover letter leaves you feeling overwhelmed, it can be tempting to turn to generative artificial intelligence (GAI) tools such as ChatGPT. But according to recruiters and employment experts, using AI could make your job application stand out for all the wrong reasons. Here are some common pitfalls and how to avoid them. Libby Sander, an associate professor of organisational behaviour at Bond University on the Gold Coast/Yugambeh Country, says GAI has become so common "that most people are going to use it in some form to put their [job] application together". It's a sentiment echoed by Fiona Macdonald, acting director of the Australia Institute's Centre for Future Work. "People are learning every day that you can use it for all sorts of things, and drafting letters is one of the things, I think, that it's being increasingly used for in the workplace," Macdonald says. Maisy Staden, a recruitment team leader based in Sydney, on the traditional lands of the Gadigal people, says she has noticed a significant increase in the number of applicants using ChatGPT to write their cover letters for them. "The difference I've noticed in the past couple of years is just the increasing similarity between cover letters that I'm receiving," she says. "If I'm seeing a cover letter that, in my opinion, is really clearly written by ChatGPT, my question is, do you have the ability to write for yourself and think for yourself?" Sander also warns that if you rely on it too heavily, "you're going to end up sounding like everybody else". "Yes, it can save time, yes, it can help you through an experience, but don't entirely rely on AI to write things for you in terms of applying for a job, because it's going to miss the unique voice that you have," she says. "Use it to get ideas and so forth, but really, you need to be thinking about it yourself." Staden says a cover letter is a recruiter or hiring manager's first impression of a candidate and an opportunity to give some insights into your personality and explain why you would be a good fit for an organisation. "If I'm seeing a personal touch or an anecdote that's relevant to the industry that we work in, I'm going to prefer that candidate much more than a generic, AI-written cover letter," she says. Sally Tredinnick, the Gold Coast-based national recruitment manager for the same agency, agrees and says it is important to "inject something about yourself, who you actually are as a person". "The CV is the user manual and the cover letter is the flashy advert, the thing that makes you want to look at the user manual," Tredinnick says. Tredinnick says it can be obvious when an applicant has used GAI to optimise their CV to make themselves look like a perfect match. "When you see a CV come through where the 10 bullet points so perfectly match the exact language, grammar of the job description, it [raises] question marks. "Then I start to doubt the authenticity of the experience that they say that they have. "What else are they feeding into ChatGPT in order to make themselves look to be the perfect candidate?" Tredinnick says a 60-70 percent match "is actually often ideal" because it provides an opportunity for growth, "and then you're going to learn, and then you're going to stay". "And what we're aiming for is for people to stay in their roles," she says. If you are going to use GAI to help with your application, Staden advises using it "as your editor, not your ghostwriter". Tredinnick says you can still use GAI to help write a cover letter that stands out from the pack if you give it the right prompts and edit the responses. She says this involves taking a more nuanced approach than simply saying, "hey, this is the job description, write me a cover letter". "If you can, think about one thing that interests you about the company, one thing that interests you about the role, three achievements that you've had in your career that are relevant to the role, and one piece of interesting information about yourself, and pop that into ChatGPT. "[Say] 'Please write a cover letter. Include this information. Don't make anything up.' If you put that through, you will get a cover letter that is authentically you, but written in a cohesive way that's actually going to be pleasant to read." - ABC

Forever-Occupation, Genocide, And Profit: Report Exposes Corporate Forces Behind Destruction Of Palestine
GENEVA (3 July 2025) – Israel's genocide against Palestinians is being sustained by a system of exploitative occupation and profit, a UN expert warned today in a new report to the Human Rights Council that reveals how corporate profiteering and monetary gain has enabled and legitimised Israel's illegal presence and actions. 'In the past 21 months, while Israel's genocide has devastated Palestinian lives and landscapes, the Tel Aviv stock exchange soared by 213 percent (USD), amassing $225.7 billion in market gains—including $67.8 billion in the past month alone. For some, genocide is profitable,' said Francesca Albanese, the UN Special Rapporteur on the situation of human rights in the Palestinian territory occupied since 1967. Albanese's report exposes the corporate infrastructure profiting from Israel's economy of occupation — and its deadly transformation into an economy of genocide. The report underscores how Palestine has become the epicentre of a global reckoning, exposing the failure of international business and legal systems to uphold even the most basic rights of one of the world's most dispossessed peoples. 'Corporate actors are deeply entwined in the system of occupation, apartheid and genocide in the occupied Palestinian territory,' the Special Rapporteur said. 'For decades, Israel's repression of Palestinian people has been scaffolded by corporations, fully aware of and yet indifferent to, decades of human rights violations and international crimes.' Forty-eight separate corporate actors, along with their parents, subsidiaries, franchisees, licensees and consortium partners across sectors are identified in the Special Rapporteur's report, including weapons manufacturers, technological corporations, financial institutions and construction and energy firms. Albanese found that these entities have failed their most basic legal responsibilities to exercise their leverage to bring an end to the violation at stake or terminate relations and disengage. Instead, they have treated Israel's illegal enterprise in the occupied Palestinian territory as ordinary economic activity—wilfully ignoring documented, systemic abuses, even as atrocities mounted after 7 October 2023. 'These actors have entrenched and expanded Israel's settler-colonial logic of displacement and replacement – and this is not accidental,' the Special Rapporteur said. 'It is the function of an economy built to dominate, dispossess, and erase Palestinians from their land.' The report named companies supplying F-35s, drones, and targeting tech that enabled 85,000 tons of bombs – six times the amount of Hiroshima – to be unleashed on Gaza. It highlighted tech giants that have set up R&D hubs and data centres in Israel, using Palestinian data for AI warfare, fueling what Albanese calls a 'livestreamed genocide.' The report points to energy giants having fuelled Israel's blockade, while construction companies continued to supply the equipment that has turned Gaza to rubble and prevented the return and reconstitution of Palestinian life. Even seemingly neutral actors – tourism sites, supermarkets, and universities are normalising apartheid and the systematic erasure of Palestinian life, the Special Rapporteur's report found. 'This report shows why Israel's genocide continues: because it is lucrative for many,' Albanese said. She warned that the International Court of Justice 2024 rulings and the ICC arrest warrants should have put all actors—including corporations—on notice. 'The serious, structural and sustained nature of Israel's crimes and violations triggered a prima facie responsibility to disengage — one that many corporations ignored,' she said. 'Corporate fixation on narrow technicalities and isolated violations rather than confronting the structural illegality of their ties to Israel's occupation is disingenuous,' she said. Albanese urged member states to impose a full arms embargo, suspend trade and investment agreements, and hold corporate entities accountable for violations of international law. 'Meanwhile, corporations cannot claim neutrality: they are either part of the machinery of displacement—or part of dismantling it.' 'Palestine is a mirror held up to the world's moral and political failures,' she said. Recalling reckonings over corporate complicity in apartheid South Africa and Nazi Germany, Albanese said Palestine today represents a defining moment of whether global markets can exist without promoting and profiting from injustice and impunity. 'Ending this genocide requires not only outrage but rupture, reckoning, and the courage to dismantle what enables it.'
