China announces plans to take on Elon Musk’s ‘Starlink’

Chinese researchers are preparing to launch close to 13,000 satellites into a low-earth orbit, in a move which would dwarf – and potentially monitor – Elon Musk’s SpaceX ‘Starlink’ network, which first launched in 2019 and provides satellite internet access to 50 countries. The project, which is codenamed ‘GW’ and is being led by associate professor Xu Can of the People’s Liberation Army’s (PLA) Space Engineering University in Beijing, will see 12,992 satellites operated by the China Satellite Network Group Co launched into orbit, and is designed to improve communications efficiency. The launch schedule remains unknown but the team led…

Under cover of Su-35, Su-30SM fighters, Russia deploys ‘highly modified’ Su-25 attack aircraft to strike Ukraine

On February 16, the Russian Ministry of Defense (RuMoD) highlighted the capabilities of the Su-25 attack aircraft upgraded by the country in a Telegram post titled ‘Upgraded Su-25SM3: Superpower Over The Battlefield’. The post was accompanied by the hashtag ‘Z,’ a letter that became the symbol of the Russian invasion in the initial weeks of the conflict, triggering speculations that the upgraded ground attack aircraft could have been deployed to Ukraine. The development is significant as it comes amid fears of an imminent aerial raid by the Russian Aerospace Forces (VKS) after several fighters and helicopters were stationed close to…

AI is going to ruin humanity – just not in the way you might expect

Attention all humans! This is Christian Guyton, your friendly TechRadar Computing Editor and definitely not a robot, here to give you a little heads up about the impacts of AI expansion on human intelligence. Now, I know what you're thinking, "AI is making our lives so much easier, why should I be worried?" And you're not wrong! AI has revolutionized many aspects of our lives, from navigation to language translation. However, if we're not careful, our reliance on AI could lead to a decline in human intelligence. When we rely on AI to answer every question, we may begin to…

Google’s Bard vs ChatGPT: Here’s what we know so far

Alphabet Inc and rival Microsoft are once again locked in a race to rule the internet zeitgeist after the Google owner launched "Bard" in answer to AI chatbot sensation ChatGPT. Just minutes after Google announced the launch of Bard on Monday, Microsoft said it would hold an event at its Redmond headquarters to reveal its own AI, potentially setting the stage for the next Chrome-versus-Internet Explorer or Gmail-versus-Hotmail. Microsoft-backed OpenAI's ChatGPT has taken the tech world by storm since it was opened for public use last year, as people worldwide got creative with prompts that the conversational chatbot uses to…

ChatGPT isn’t a great leap forward, it’s an expensive deal with the devil

Sometimes, those who would forget history are condemned to repeat it. For those of us with long memories, the current fuss – nay hysteria – surrounding ChatGPT(and “generative AI” generally) rings a bell. We have been here before: in January 1996, to be precise. That was the moment when Joseph Weizenbaum, a computer scientist at MIT, unveiled Eliza, which would have been called the world’s first chatbot if that term had existed at the time. Weizenbaum wrote the software (in a programming language intriguingly called MAD-SLIP) to demonstrate that communications between humans and computers were inevitably superficial. It did that…

Russia and Ukraine battle daily in the sky. So where are the pilots?

Russia and Ukraine are waging a fierce fight in the sky. Russia unleashes drones and missiles. Ukraine often shoots them down with its own missiles, and carries out its own drone strikes. Yet one thing makes this battle distinctive from all previous air wars of the past century: pilots are rare. And this goes very much against the traditional perception of air combat. "Top Gun: Maverick is Oscar-nominated this year for Best Picture. And here we are, watching an air war happening. And it looks very different from anything that we see in Top Gun," said Kelly Grieco, with the…

Scientists can now use WiFi to see through people's walls

It isn’t immediately clear how using only a WiFi signal to track human movement through walls improves personal privacy... but that’s what a new study from Carnegie Mellon University claims. In a recently published paper, the researchers expanded on the study of employing WiFi signals to map human movement, especially in low-light situations that make using other technologies less than desirable. They write: “We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of…

Russian Navy takes delivery of ‘weapon of the apocalypse’ as Putin delivers on strategic threat

The Russian Navy has taken delivery of the first nuclear submarine drones announced under Vladimir Putin’s strategic weapons program in March 2018. Tests on the Poseidon nuclear-powered unmanned underwater vehicle (UUV) have concluded, and the system will soon be deployed on one of Moscow’s new-generation submarines, according to Russian media reports. In the context of the Kremlin’s invasion of Ukraine, NATO has expressed its concern over Poseidon, which is capable of delivering both nuclear and conventional warheads, triggering tsunamis and contaminating vast expanses of water with radioactive materials. “Russia still has the greatest nuclear potential in the world, but nobody…

This 22-year-old is trying to save us from ChatGPT before it changes writing forever

While many Americans were nursing hangovers on New Year's Day, 22-year-old Edward Tian was working feverishly on a new app to combat misuse of a powerful, new artificial intelligence tool called ChatGPT. Given the buzz it's created, there's a good chance you've heard about ChatGPT. It's an interactive chatbot powered by machine learning. The technology has basically devoured the entire Internet, reading the collective works of humanity and learning patterns in language that it can recreate. All you have to do is give it a prompt, and ChatGPT can do an endless array of things: write a story in a…

Scientists reach key milestone on how to reverse aging

It’s been 13 years in the making, but David Sinclair and his colleagues have finally answered the question of what drives aging. In a study published Jan. 12 in Cell, Sinclair, a professor of genetics and co-director of the Paul F. Glenn Center for Biology of Aging Research at Harvard Medical School, describes a groundbreaking aging clock that can speed up or reverse the aging of cells. Scientists studying aging have debated what drives the process of senescence in cells—and primarily focused on mutations in DNA that can, over time, mess up a cell’s normal operations and trigger the process…

Universities return to ‘pen and paper’ exams after students caught using AI to write exams

Australian universities have been forced to change the way they run exams and other assessments amid fears students are using emerging artificial intelligence software to write essays. Major institutions have added new rules which state that the use of AI is cheating, with some students already caught using the software. But one AI expert has warned universities are in an “arms race” they can never win. ChatGPT, which generates text on any subject in response to a prompt or query, was launched in November by OpenAI and has already been banned across all devices in New York’s public schools due…

New wireless TV runs on batteries for 30 days, sticks to wall without mounting hardware

I met Apple's driving force Steve Jobs a few years before his passing. What he imparted stuck with me. If there was one thing he did well, it was innovating with a focus on balancing design with function. The aesthetic meeting point nailed it like no one had ever achieved. You remember in Apple's days of disruptive innovation, Jobs replaced the Sony Walkman with a revolutionary iPod, he took the inside of cellular phones away from wireless providers and reimagined a phone becoming more like a computer on the go with the iPhone. He took a boring gray desktop computer…
