'Writing Is Thinking': Do Students Who Use ChatGPT Learn Less?
"It was very clear that ChatGPT had decided this is a common woman's name," said Leitzinger, who teaches an undergraduate class on business and society at the University of Illinois in Chicago.
"They weren't even coming up with their own anecdotal stories about their own lives," she told AFP.
Leitzinger estimated that around half of her 180 students used ChatGPT inappropriately at some point last semester -- including when writing about the ethics of artificial intelligence (AI), which she called both "ironic" and "mind-boggling".
So she was not surprised by recent research which suggested that students who use ChatGPT to write essays engage in less critical thinking.
The preprint study, which has not been peer-reviewed, was shared widely online and clearly struck a chord with some frustrated educators.
The team of MIT researchers behind the paper have received more than 3,000 emails from teachers of all stripes since it was published online last month, lead author Nataliya Kosmyna told AFP.
For the small study, 54 adult students from the greater Boston area were split into three groups. One group used ChatGPT to write 20-minute essays, one used a search engine, and the final group had to make do with only their brains.
The researchers used EEG devices to measure the brain activity of the students, and two teachers marked the essays.
The ChatGPT users scored significantly worse than the brain-only group on all levels. The EEG showed that different areas of their brains connected to each other less often.
And more than 80 percent of the ChatGPT group could not quote anything from the essay they had just written, compared to around 10 percent of the other two groups.
By the third session, the ChatGPT group appeared to be mostly focused on copying and pasting.
The teachers said they could easily spot the "soulless" ChatGPT essays because they had good grammar and structure but lacked creativity, personality and insight.
However Kosmyna pushed back against media reports claiming the paper showed that using ChatGPT made people lazier or more stupid.
She pointed to the fourth session, when the brain-only group used ChatGPT to write their essay and displayed even higher levels of neural connectivity.
Kosmyna emphasised it was too early to draw conclusions from the study's small sample size but called for more research into how AI tools could be used more carefully to help learning.
Ashley Juavinett, a neuroscientist at the University of California San Diego who was not involved in the research, criticised some "offbase" headlines that wrongly extrapolated from the preprint.
"This paper does not contain enough evidence nor the methodological rigour to make any claims about the neural impact of using LLMs (large language models such as ChatGPT) on our brains," she told AFP.
Leitzinger said the research reflected how she had seen student essays change since ChatGPT was released in 2022, as both spelling errors and authentic insight became less common.
Sometimes students do not even change the font when they copy and paste from ChatGPT, she said.
But Leitzinger called for empathy for students, saying they can get confused when the use of AI is being encouraged by universities in some classes but is banned in others.
The usefulness of new AI tools is sometimes compared to the introduction of calculators, which required educators to change their ways.
But Leitzinger worried that students do not need to know anything about a subject before pasting their essay question into ChatGPT, skipping several important steps in the process of learning.
A student at a British university in his early 20s who wanted to remain anonymous told AFP he found ChatGPT was a useful tool for compiling lecture notes, searching the internet and generating ideas.
"I think that using ChatGPT to write your work for you is not right because it's not what you're supposed to be at university for," he said.
The problem goes beyond high school and university students.
Academic journals are struggling to cope with a massive influx of AI-generated scientific papers. Book publishing is also not immune, with one startup planning to pump out 8,000 AI-written books a year.
"Writing is thinking, thinking is writing, and when we eliminate that process, what does that mean for thinking?" Leitzinger asked. A recent viral study suggested that students who use ChatGPT to write essays engage in less critical thinking AFP

Visa's 24/7 War Room Takes On Global Cybercriminals
In the heart of Data Center Alley -- a patch of suburban Washington where much of the world's internet traffic flows -- Visa operates its global fraud command center. The numbers that the payments giant grapples with are enormous. Every year, $15 trillion flows through Visa's networks, representing roughly 15 percent of the world's economy. And bad actors constantly try to syphon off some of that money. Modern fraudsters vary dramatically in sophistication. To stay ahead, Visa has invested $12 billion over the past five years building AI-powered cyber fraud detection capabilities, knowing that criminals are also spending big. "You have everybody from a single individual threat actor looking to make a quick buck all the way to really corporatized criminal organizations that generate tens or hundreds of millions of dollars annually from fraud and scam activities," Michael Jabbara, Visa's global head of fraud solutions, told AFP during a tour of the company's security campus. "These organizations are very structured in how they operate." The best-resourced criminal syndicates now focus on scams that directly target consumers, enticing them into purchases or transactions by manipulating their emotions. "Consumers are continuously vulnerable. They can be exploited, and that's where we've seen a much higher incidence of attacks recently," Jabbara said. The warning signs are clear: anything that seems too good to be true online is suspicious, and romance opportunities with strangers from distant countries are especially dangerous. "What you don't realize is that the person you're chatting with is more likely than not in a place like Myanmar," Jabbara warned. He said human-trafficking victims are forced to work in multi-billion-dollar cyber scam centers built by Asian crime networks in Myanmar's lawless border regions. The most up-to-date fraud techniques are systematic and quietly devastating. Once criminals obtain your card information, they automatically distribute it across numerous merchant websites that generate small recurring charges -- amounts low enough that victims may not notice for months. Some of these operations increasingly resemble legitimate tech companies, offering services and digital products to fraudsters much like Google or Microsoft cater to businesses. On the dark web, criminals can purchase comprehensive fraud toolkits. "You can buy the software. You can buy a tutorial on how to use the software. You can get access to a mule network on the ground or you can get access to a bot network" to carry out denial-of-service attacks that overwhelm servers with traffic, effectively shutting them down. Just as cloud computing lowered barriers for startups by eliminating the need to build servers, "the same type of trend has happened in the cyber crime and fraud space," Jabbara explained. These off-the-shelf services can also enable bad actors to launch brute force attacks on an industrial scale -- using repeated payment attempts to crack a card's number, expiry date, and security code. The sophistication extends to corporate-style management, Jabbara said. Some criminal organizations now employ chief risk officers who determine operational risk appetite. They might decide that targeting government infrastructure and hospitals generates an excessive amount of attention from law enforcement and is too risky to pursue. To combat these unprecedented threats, Jabbara leads a payment scam disruption team focused on understanding criminal methodologies. From a small room called the Risk Operations Center in Virginia, employees analyze data streams on multiple screens, searching for patterns that distinguish fraudulent activity from legitimate credit card use. In the larger Cyber Fusion Center, staff monitor potential cyberattacks targeting Visa's own infrastructure around the clock. "We deal with millions of attacks across different parts of our network," Jabbara noted, emphasizing that most are handled automatically without human intervention. Visa maintains identical facilities in London and Singapore, ensuring 24-hour global vigilance.

AI Robots Fill In For Weed Killers And Farm Hands
Oblivious to the punishing midday heat, a wheeled robot powered by the sun and infused with artificial intelligence carefully combs a cotton field in California, plucking out weeds. As farms across the United States face a shortage of laborers and weeds grow resistant to herbicides, startup Aigen says its robotic solution -- named Element -- can save farmers money, help the environment and keep harmful chemicals out of food. "I really believe this is the biggest thing we can do to improve human health," co-founder and chief technology officer Richard Wurden told AFP, as robots made their way through crops at Bowles Farm in the town of Los Banos. "Everybody's eating food sprayed with chemicals." Wurden, a mechanical engineer who spent five years at Tesla, went to work on the robot after relatives who farm in Minnesota told him weeding was a costly bane. Weeds are becoming immune to herbicides, but a shortage of laborers often leaves chemicals as the only viable option, according to Wurden. "No farmer that we've ever talked to said 'I'm in love with chemicals'," added Aigen co-founder and chief executive Kenny Lee, whose background is in software. "They use it because it's a tool -- we're trying to create an alternative." Element the robot resembles a large table on wheels, solar panels on top. Metal arms equipped with small blades reach down to hoe between crop plants. "It actually mimics how humans work," Lee said as the temperature hit 90 degrees Fahrenheit (32 degrees Celsius) under a cloudless sky. "When the sun goes down, it just powers down and goes to sleep; then in the morning it comes back up and starts going again." The robot's AI system takes in data from on-board cameras, allowing it to follow crop rows and identify weeds. "If you think this is a job that we want humans doing, just spend two hours in the field weeding," Wurden said. Aigen's vision is for workers who once toiled in the heat to be "upskilled" to monitor and troubleshoot robots. Along with the on-board AI, robots communicate wirelessly with small control centers, notifying handlers of mishaps. Aigen has robots running in tomato, cotton, and sugar beet fields, and touts the technology's ability to weed without damaging the crops. Lee estimated that it takes about five robots to weed 160 acres (65 hectares) of farm. The robots made by the 25-person startup -- based in the city of Redmond, outside Seattle -- are priced at $50,000. The company is focused on winning over politically conservative farmers with a climate friendly option that relies on the sun instead of costly diesel fuel that powers heavy machinery. "Climate, the word, has become politicized but when you get really down to brass tacks farmers care about their land," Lee said. The technology caught the attention of Amazon Web Services (AWS), the e-commerce giant's cloud computing unit. Aigen was chosen for AWS's "Compute for Climate" fellowship program that provides AI tools, data center power, and technical help for startups tackling environmental woes. "Aigen is going to be one of the industry giants in the future," said AWS head of climate tech startups business development Lisbeth Kaufman. "I think about Ford and the Model T, or Edison and the light bulb -- that's Kenny and Rich and Aigen."

Meltdown: Swiss Glaciers Hit Annual Tipping Point Weeks Early
The snow and ice accumulated last winter by Switzerland's glaciers has already melted away, a monitoring service said, with Friday marking the alarming second-earliest arrival on record of the tipping point known as glacier loss day. All further melting between now and October will see the size of glaciers in the Swiss Alps shrink, according to Glacier Monitoring in Switzerland (GLAMOS). This century, the tipping point, on average, has been reached in mid-August -- itself already bad news for the nation's 1,400 glaciers, which are shrinking at a staggering rate. Its arrival several weeks earlier on July 4 is "another alarm call", GLAMOS chief Matthias Huss told AFP. "It's like the glaciers are shouting out: 'We're disappearing. Help us.'" Glaciers in the Swiss Alps began to retreat about 170 years ago. The retreat was initially modest but in recent decades, melting has accelerated significantly as the climate warms. The volume of Swiss glaciers shrank by 38 percent between 2000 and 2024. "If we have a glacier loss day, it means that the glacier is losing mass," said Huss. "For a glacier that is healthy, the day would occur at the end of September, or in October -- or not at all". With no glacier loss day, the summer would simply melt away only the snow that accumulated over the previous winter. This would be "the ideal case -- a glacier in equilibrium with the climate", said Huss. Its arrival on July 4 means that "critically, we have the whole summer left to destroy the ice". "Moving this day forward by five to six weeks before the normal date over the last 20 years means we're just prolonging this mass loss season dramatically," he said. The assessment is made using 12 reference glaciers. Last winter saw low levels of snowfall, and June was the second warmest on record, contributing to the day's early arrival this year. In data going back to 2000, the only time that the tipping point arrived even earlier was in 2022, when it came on June 26. "That was really a game-changer for us glaciologists because it was the first year when we saw absolutely extreme melting. "Everything that we knew before about glacier melting changed," said Huss. Experts thought 2022 was a complete outlier and although a warming climate meant other such years would be coming down the line, they did not expect to see the next very early glacier loss day coming so soon afterwards. Huss noted that extreme melting produces an accelerating feedback effect, worsening the situation even further. Once the reflective white snow coverage from winter is gone from the top of the glacier, the darker, more absorbent grey surface of the bare ice is exposed. "With the same amount of solar radiation, we can now melt more ice," Huss said. With the European heatwave over the past week and the possibility of further heatwaves in July and August, "it is very like that again it is a very bad year for Swiss glaciers", he said. Melting glaciers threatens the long-term water security for millions of people downstream who rely on them for fresh water. Much of the water that flows into the Rhine and the Rhone, two of Europe's major rivers, comes from the Alpine glaciers.
