Při zásahu bleskem je lepší být suchý, nebo promoklý?

V Durynsku, zhruba sto kilometrů od našich Hranic je Město Ilmenau. V něm sídlí Technická univerzita vybavená zařízením na výboje takové intenzity, že imitují blesky. Právě tam se parta Jense Haueisena z Institutu biomedicínského inženýrství a informatiky jala ověřit, co nám při bouřce může zachránit život. http://www.osel.cz/13357-pri-zasahu-bleskem-je-lepsi-byt-suchy-nebo-promokly.html

Hackers are hunting celebs. Digital IDs can help — but come with caveats

Astronomers found a quasar fueled by a giant black hole that eats a sun a day

The brightest object in the universe—at least, the brightest we’ve seen yet—shines 500 trillion times brighter than the sun, and it eats a sun a day.

Objects like these are rare, and despite their objective brightness, remain elusive and hard to spot. This record-breaker was first spotted in 1980 and mischaracterized as a regular old star. Then, in a study conducted by a team out of Australia using the Siding Spring Observatory, it was recast as a quasar. Observ

A case for making our AI chatbots more confrontational

Spend any time interacting with AI chatbots and their tone can start to grate. No question is too taxing or intrusive for the noncorporial assistants, and if you probe under the hood of the bot too much, it’ll respond in a platitudinous way designed to dullen the interaction.

Nearly a year and a half into the generative-AI revolution, researchers are starting to wonder whether that deathly dull format is the best approach.

Nový soukromý modul dosedl na povrch Měsíce

Dnes došlo k dalšímu zlomu v návratu na Měsíc. Po startu soukromou raketou Falcon 9 firmy Space X a týdenním letu dorazil měsíční modul Odysseus firmy Intuitive Machines k Měsíci, a nakonec úspěšně přistál. Opět to bylo v blízkosti pólu, tentokrát ještě jižněji. Jde o návrat USA na Měsíc po dlouhých téměř 52 letech a také první soukromé přistání. Podívejme se tak na tuto událost i další novinky z povrchu našeho souputníka podrobněji.

Nvidia stock surge could catapult Jensen Huang into the top 20 world’s richest people

Google pulls the plug on Gemini AI image generation after being mocked for revisionist history

Google said Thursday it’s temporarily stopping its Gemini artificial intelligence chatbot from generating images of people a day after apologizing for “inaccuracies” in historical depictions that it was creating.

Gemini users this week posted screenshots on social media of historically white-dominated scenes with racially diverse characters that they say it generated, leading critics to raise questions about whether the company is overcorrecting for the risk of

3D printing brings more efficient ways to make rocket propellants

Imagine you’re driving to work on a rainy day, when a distracted, reckless driver hits your car out of nowhere. With a “boom,” an airbag deploys faster than you can blink your eyes to save your life.

That airbag deployed rapidly thanks to an energetic material called sodium azide, which generates nitrogen gas during a chemical reaction to inflate your airbag. But what’s an energetic material?

Energetic materials include prope

These three companies show why the next AI wave won’t revolve around chatbots

For all the considerable—and, yes, over-the-top—attention that artificial intelligence has received since ChatGPT first launched in 2022, we still mostly interact with this new form of computing in an old school way: We type, the chatbot answers.

Still, AI chatbots have become so immensely popular—used by something like one-third of Americans, per one survey last summer—that there’s already talk of a bot bubble.But chatbots may not be the future&#x

Meet the shady companies helping governments hack citizens’ phones

Named for the winged horse of Greek mythology and often sent by text message, Pegasus can burrow into your phone without your knowledge or even your click, hiding for days or weeks inside, surreptitiously recording everything—messages, photos, encrypted chats, and video and audio—in real-time. Exactly where your data is going often remains a mystery, lost in a tangle of servers. But the deadly impacts of Pegasus and other cyberweapons—wielded by governments from Spain to

AI stocks are on a wild ride today after Nvidia stunned Wall Street with staggering growth

Yesterday, Nvidia Corporation announced its Q4 results, which saw a staggering 265% increase from the same quarter a year earlier. The blowout quarter was once again driven by a demand for the company’s chips, which power, among other things, many of the AI technologies used today—like the servers that run ChatGPT.

In the wake of its earnings, Nvidia Corporation shares (ticker: NVDA) are up over 14.5% in premarket trading to $773, as of the time of this writing. But in

Bad week for EV makers: Rivian to lay off 10% of workforce while Lucid struggles to find buyers

Electric vehicle makers are having a bad week. First up is Lucid Group, which announced Q4 2023 results yesterday. While the company produced and delivered 37% more vehicles in 2023 than it did in 2022, its 2024 outlook was pretty grim news to investors.

Lucid said its production guidance for 2024 was only 9,000 vehicles, suggesting the company is struggling to find buyers for its EVs. As TechCrunch notes, that’s just 10% of the 90,000 EVs the company predicted when it went p

By sunsetting Freevee, Amazon would be doubling down on keeping ads in Prime Video

Anyone hoping the pronounced backlash to this initiative might be enough to convince Amazon to walk it back, however, is about to be disappointed.

Why Nvidia’s record 265% revenue growth is moving the whole stock market

Nvidia, on Wednesday, posted record Q4 revenue of $22 billion, boasting a 265% increase from the same quarter the prior year and earnings that blew past expectations. Yet, in the immediate aftermath of those earnings, the stock fell 3% in the after-hours market.
