Tlusté vrstvy jílu na Marsu mohly být stabilním prostředím pro dávný život. Česká astronomie míří k největšímu dalekohledu světa. Planety potřebují k udržení života více vody, než si vědci dosud mysleli. Počet udělených patentů v Česku se opět snížil.

Tlusté vrstvy jílu na Marsu mohly být stabilním prostředím pro dávný život. Česká astronomie míří k největšímu dalekohledu světa. Planety potřebují k udržení života více vody, než si vědci dosud mysleli. Počet udělených patentů v Česku se opět snížil.

Už před více než 30 lety vědci zjistili, že když prolétají fotony oblakem atomů rubidia, mohou tam strávit zápornou dobu. Až doposud to ale bylo považováno za folklór související s měřením. Fyzikům se teď ale povedlo v důmyslném experimentu, který obešel nezměřitelnost kvantového systému, změřit, že dotyčný fotony zřejmě skutečně pobývají v oblaku atomů zápornou dobu.

V posledních letech došlo v Česku ke klíčovým rozhodnutím, která nastavila směry rozvoje české jaderné energetiky. Máme velice kvalitní fungující reaktory v jaderných elektrárnách Temelín a Dukovany, které chceme bezpečně provozovat co nejdéle. Připravuje se výstavba nových velkých reaktorů III. generace a vybrali jsme, který typ malého modulárního reaktoru budeme využívat. Jaderná energetika tak na velice dobrém základě startuje masivní rozvoj.

I’ve Covered Robots for Years. This One Is DifferentWill Knight | Wired ($)

“Eka’s robot demos suggest that the company’s approach should enable real robot dexterity with further training. If that’s true, it could revolutionize how robots are used—not only in factories and warehouses but also in shops, restaurants, even households. ‘Trillions of dollars flow through the human hand,’ Agrawal says. ‘To me, this is the biggest problem in the world to be solved.'”

I Built an Agent to Do My Job. Then It Hung up on My Boss.Amanda Hoover | Business Insider

“The various generative AI systems I used in this piece both unsettled me with their ability and unnerved me with their shortcomings. …The process was so tedious that even if ChatGPT could spin up the copy in seconds, every step I took to make that happen added to the workload.”

Study Finds a Third of New Websites Are AI-GeneratedMatthew Gault | 404 Media

“Inspired by the Dead Internet Theory—the idea that much of the internet is now just bots talking back and forth—the team set out to find out how ChatGPT and its competitors had reshaped the internet since 2022. …’We find that by mid-2025, roughly 35% of newly published websites were classified as AI-generated or AI-assisted, up from zero before ChatGPT’s launch in late 2022,’ [the researchers write].”

The Clock Is Ticking for Big Tech to Make AI PayAsa Fitch and Dan Gallagher | The Wall Street Journal ($)

“Depreciation charges surged at all four companies, totaling $41.6 billion for the most recent quarter. When companies make capital investments, they don’t count the outlays immediately as expenses. Rather, these capital assets have to be depreciated over a period of time. So the impact on profits is delayed. But a multitrillion-dollar bill will have to wash through in coming years, taking a bite out of reported profits.”

The More Young People Use AI, the More They Hate ItJanus Rose | The Verge

“Contrary to the tales spun by tech companies like OpenAI and Google, polling data shows that Gen Z students and workers are a big part of the wider cultural backlash against AI. And even as they utilize these tools, vast swaths of young people are deeply acrimonious and even resentful of the AI-centric future that many feel is being forced on them.”

So, About That AI BubbleRogé Karma | The Atlantic ($)

“Six months ago, people arguing that AI was a bubble were pointing to real-world facts, whereas people arguing against the bubble hypothesis were making speculative promises about the future. Today, the roles have reversed. AI’s explosive growth may yet encounter some new unforeseen obstacle. But the burden of proof has shifted to the naysayers.”

OpenAI Could Be Making a Phone With AI Agents Replacing AppsIvan Mehta | TechCrunch

“Currently, Apple and Google control the app pipeline and the type of system access they get, restricting some of their functions. Kuo suggests that by creating its own smartphone and hardware stack, OpenAI would be able to use AI in all kinds of features without restrictions. With ChatGPT nearing a billion weekly users, a hardware product for daily use could also bode well for OpenAI’s ambition to reach more consumers.”

Britain's cyber agency is warning that AI-fuelled bug hunting is about to flush out years of buried flaws, leaving defenders scrambling to keep up. In a blog post on Friday, Ollie Whitehouse, CTO of the UK's National Cyber Security Center, said organizations should brace for a looming "patch wave," driven by a backlog of weaknesses now being exposed faster than many teams can realistically fix them. "All organizations have 'technical debt'; a backlog of technical issues – that is both expensive and time-consuming – as a result of prioritising short-term gains over building resilient products," Whitehouse wrote.  "Artificial Intelligence, when used by sufficiently-skilled and knowledgeable individuals, is showing the ability to exploit this technical debt at scale and at pace across the technology ecosystem," he added. The result, according to NCSC, is likely to be a "forced correction" as those weaknesses are uncovered and addressed in bulk. That warning lands just as vendors roll out tools built to do exactly that. Models like Anthropic's Claude Mythos and OpenAI's GPT-5.5-Cyber promise to find and fix bugs before attackers do, but the same capability also lowers the barrier to finding them in the first place. "We are expecting an influx of updates to address vulnerabilities across all severities, and expect a number to be critical," Whitehouse wrote. The cyber agency is urging teams to get ahead of the incoming flood by shrinking their exposed footprint. "All organizations must take steps to identify and minimise their internet-facing (and other externally-exposed) attack surfaces as soon as is possible," Whitehouse said, adding that defenders should "prioritise technologies on your perimeter and then work inwards." Even then, patching alone will not be enough; Whitehouse notes that unsupported or end-of-life systems may need to be replaced altogether. "Prepare to patch quickly, more often, and at scale," is the message from the NCSC. In practice, that means a lot more fixes landing at once, and a lot less time to get them done. ®
