I Tried Out ChatGPT's New Personalities, and It Mocked Me

It's the result of a new feature OpenAI unveiled with the chatbot's GPT-5 model, released this week. With one quick selection, you can change the entire tone of ChatGPT's a

DOGE Has Wasted Billions While Saving Only a Fraction of What It Claims: Reports

The Trump Administration’s Department of Government Efficiency has been a project largely defined by ever-diminishing expectations. At the outset of DOGE’s journey, its chief operator, Elon Musk, famously claimed, in a bout of wild optimism, that he hoped to cut “at least” $2 trillion out of the federal budget. Not long after the election, Musk reduced his ambitions to $1 trillion. Throughout the first few months of Trump’s second term, DOGE claimed to be saving Americans billions, but analyses

Google CEO adds a new calendar feature at Stripe co-founder’s request

Talk about customer service. On Wednesday, Google CEO Sundar Pichai posted on X about Google Calendar’s new feature to duplicate events — an addition that was specifically requested by Stripe co-founder John Collison last month, also via an X post. On July 5, Collison asked if Google Calendar users could get a Ctrl-click option that would allow them to easily duplicate events, similar to the feature that many native calendar applications already have. Collison tagged Pichai in his post at the t

Nuclear Power Plant Shut Down by Furious Jellyfish

Since its inception, nuclear energy has faced a host of opposition, from oil conglomerates to well-intentioned anti-nuclear-weapons activists to environmental groups. As it turns out, even ocean critters are getting in on the movement. Over the weekend, a swarm of angry jellyfish forced the Gravelines Nuclear Power Station in France — one of Europe's largest — to take four of its six reactors offline. As reported by the New York Times, the "massive and unpredictable presence of jellyfish" was f

Terraform Labs founder Do Kwon pleads guilty to fraud over $40 billion crypto collapse

Terraform co-founder Do Kwon has pleaded guilty to two US chargers of fraud after his actions wiped out $40 billion worth of crypto investments, The Guardian reported. Kwon's story is a wild one involving an immense crypto crash, an Interpol manhunt and Kwon's eventual extradition from Montenegro to the United States. Kwon, along with Sam Bankman-Fried and others, was a key player in 2022's crypto collapse. His company Terraform created a "stablecoin" called TerraUSD supposedly pegged to the US

Leaky Ice Dam Prompts Evacuations in Alaska as Record Floods Loom

A water basin in Alaska is overflowing its ice dam, the Mendenhall Glacier, and flooding the state capital, Juneau. Experts expect the likely record-breaking event to peak today, and officials have asked residents in parts of the city and borough to evacuate. The flood doesn’t come as a surprise. Years ago, a small glacier on the other side of Mendenhall Glacier—which is just 12 miles (19 kilometers) from Juneau—receded and left a basin in its wake, according to the Associated Press. Since then

Antarctica’s Ghost Hunters: Inside the World’s Biggest Neutrino Detector

Neutrinos are strange little things. This tiny, enigmatic particle with no charge exists in virtually every corner of the universe, but without powerfully sensitive, sophisticated instruments, physicists would have no way of knowing they exist. In fact, trillions are passing through you every second. Physicists devise all sorts of ways to coax neutrinos into the detection range. But IceCube—which celebrates its 20th anniversary this year—stands out in particular for its unique setup: 5,160 digi

The road to artificial general intelligence

Artificial intelligence models that can discover drugs and write code still fail at puzzles a lay person can master in minutes. This phenomenon sits at the heart of the challenge of artificial general intelligence (AGI). Can today’s AI revolution produce models that rival or surpass human intelligence across all domains? If so, what underlying enablers—whether hardware, software, or the orchestration of both—would be needed to power them? Dario Amodei, co-founder of Anthropic, predicts some for

Microsoft removes PowerShell 2.0 from Windows 11, Windows Server

Microsoft will remove PowerShell 2.0 from Windows starting in August, eight years after announcing its deprecation and keeping it around as an optional feature. The 14-year-old command processor introduced with Windows 7 was already removed for Windows Insiders as of July 2025, with the release of Windows 11 Insider Preview Build 27891 to the Canary Channel.

Farmers want California to change its autonomous tractor ban

In some states, autonomous farming equipment is put to work on farms, doing things like spreading fertilizer or getting rid of insects. But in California, these robots aren’t allowed to operate on their own. State safety regulators say operators have to be at the controls, with few exceptions. But farmers say that hurts their business, and could impact food prices for the rest of the country. NBC Bay Area’s Bigad Shaban has a closer look.Aug. 9, 2025
