Antické mauzoleum v roli opuštěné katedrály ostrova Sikinu, 3. a 7. století

Na kykladský ostrov Sikinos přišla v římské době bohatší rodina z maloasijské Lýkie a podle svého zvyku si pod horami postavila v 3. století mauzoleum. V 7. století bylo přestavěno na katedrálu, nakonec znovu trochu přestavěno při opravě v 17. století. Pak bylo biskupství opuštěno, v našem století se celek dočkal výzkumu a restaurování. http://www.osel.cz/13994-anticke-mauzoleum-v-roli-opustene-katedraly-ostrova-sikinu-3-a-7-stoleti.html

How people secured their secrets before encyption

Centuries before encrypted texts and secure video conferencing, people relied on physical engineering to keep their written messages sturdy, sealed, and secure against eavesdroppers.

In a new book, researchers Jana Dambrogio and Daniel Starza Smith outline the “letterlocking” techniques used by figures from Queen Elizabeth I to poet Emily Dickinson to protect their paper letters—and the methods Dambrogi

Quantum computing could change science forever—if it works

Artificial intelligence has transformed how companies process data and make decisions—but Silicon Valley’s biggest players are already chasing what could be the next technological breakthrough: quantum computing. Unlike AI, which accelerates existing processes, quantum computing promises to unlock entirely new capabilities, from simulating molecules for drug discovery to solving problems far beyond the reach of today’s fastest supercomputers. The industry is projected to

Section 230 helped create the internet. What happens if it goes away?

Section 230 of the Communications Decency Act, passed in 1996 as part of the Telecommunications Act, has become a political lightning rod in recent years. The law shields online platforms from liability for user-generated content while allowing moderation in good faith.

Lawmakers including Sens. Lindsey Graham, R-S.C., and Dick Durbin, D-I

Steve Jobs was probably the last beloved tech leader the world will ever have—and that’s a good thing

Almost 23 years ago, an employee at Apple described Steve Jobs to me as one of the world’s few “rock star CEOs.” At the time, I didn’t understand why anyone would talk about the head of a company in that way. A rock star was an artist who defined the cultural moment and attracted a legion of rabid fans. A CEO was just a CEO, right?

In my defense, I was young. I knew little about Jobs’s personal background or his impact on tech sector—this was just over a year after Apple had

‘Build up your emergency fund’: Millennials are sharing recession survivals tips on TikTok

Millennials were told the 2008 recession was a “once in a generation” economic crisis. Almost two decades later, déjà vu has struck.

5 things to know about Meta’s upcoming FTC trial

Meta is set to face off against the U.S. Federal Trade Commission on Monday in an antitrust trial that could force the social media giant to divest Instagram and WhatsApp.

The next big AI shift in media? Turning news into a two-way conversation

When people talk about how AI might reshape media, the term “hyper-personalization” comes up a lot. In broad terms, it means that AI can tailor the experience around your preferences—assuming it has enough data about you. To some extent, algorithms and ad tech have been doing this for years, recommendi

This tiny screw is powering the humanoid robot revolution

The humanoid robotics revolution is just around the corner. Test models are already working in factories alongside human beings across the world, while AI companies develop new foundation models designed to help robots navigate their environments as easily as humans do.

IPOs are being pulled and the market is yo-yoing. What’s next?

Calling this a chaotic week on Wall Street might be underselling the situation. We’ve seen drops of more than 2,000 points in the Dow and then gains of even more. In the past five days, the Dow has swung almost 3,300 points.

That volatility has pushed more than a dozen companies to shelve their IPO plans, including some of the year’s most-highly anticipated debuts.

Why I read 597 applications for one job—no AI involved

Last month I posted a job description on our blog for a chief of staff role at my venture capital firm, Graham & Walker. Turns out, that job description really hit a nerve. Within an hour, more than a hundred candidates had put their hat in the ring and filled out the long Google form that served as our only form of application.

Quickly overwhelmed by the interest, I asked everyone I knew for tips on how to review all those applications most efficiently. They recommended several to

Záhadná čelist z moře u Tchaj-wanu se proměnila v nejlepší fosilii denisovana

V roce 2015 vylovili rybářskou sítí z mořského dna poblíž Peskadorských ostrovů čelist z lidské linie, ze které se nepodařilo vytáhnout DNA. Paleoprotemika ukázala na muže denisovana, který žil asi před 10 až 190 tisíci let.

What the ‘Bhagavad Gita’ can teach us about AI

One recent rainy afternoon, I found myself in an unexpected role—philosophy teacher to a machine. I was explaining the story of the Bhagavad Gita to a leading large language model, curious to see if it could grasp the lessons at the heart of one of the world’s most profound philosophical texts. The LLM’s responses were impressively structured and fluent. They even sounded reflective at times, giving a sense that the

‘Somebody has to pay the cost’: Business owners break down tariff drama on social media

Founders and CEOs typically use social media to etch a human face onto their brand, forge a personal connection with potential customers, and put some pizzazz into product launches.

With the thundercloud of steep global tariffs looming overhead, though, many business owners have lately turned to TikTok, Instagram, and Reddit to explain the economic havoc those tariffs are poised to wreak on their brands—and in some cases, to search for a path forward.
