„Beam-down“ solární reaktor vyrábí zelený vodík bez elektřiny

Průmysl potřebuje vodík kvůli dekarbonizaci, ale výroba vodíku je sama o sobě velmi energeticky náročná. Má-li zezelenat, je nutné nahradit tradiční elektrolýzu vodíku důmyslnějšími procesy. Zajímavým kandidátem je „beam-down“ solární reaktor, který pohání výrobu vodíku termosolárním žárem, nasbíraným velkou soustavou zrcadel. http://www.osel.cz/14128-beam-down-solarni-reaktor-vyrabi-zeleny-vodik-bez-elektriny.html

The rise of the personal AI advisors

When a viral Reddit post revealed that ChatGPT cured a five-year medical mystery in seconds, even LinkedIn’s Reid Hoffman took notice. Now, OpenAI’s Sam Altman says Gen Z and Millennials are treating AI chatbots as “life advisors.” The next step? Always-on AI agents tailored to your health, career, finances, and relationships, a future where personalized AI assistants could redefine how we seek information, leaving traditional search engines in the dust.

This free read-it-later app is the perfect replacement for Pocket

Want to save pages on the web for later? You could always bookmark them in your browser of choice, of course. But that’s a quick way to end up with a messy bookmarks toolbar. And organizing your browser’s bookmarks isn’t exactly a pleasant experience.

Services like Pocket solved this problem in their own way, letting you save a collection of things you wanted to read later—and organize that collection. Mozilla

Meet Delphi, the AI startup that lets experts turn themselves into chatbots

Everyone who’s ever talked to ChatGPT, Claude, Gemini, and other big-name chatbots recognizes how anodyne they can be. Because these conversational AIs’ creators stuff them with as much human-generated training content as possible, they don’t end up sounding like anyone in particular. Instead—to borrow the title of a 1986 book by philosopher Thomas Nagel—they offer the view from nowhere.

But what if you could train a

Bilt to last? Inside the points-obsessed startup that rewards you for paying rent on time

The night is young when Bilt Rewards founder and CEO Ankur Jain steps inside Manhattan’s ABC Cocina restaurant on a Monday in early spring. Vintage chandeliers glint overhead as the 35-year-old Jain, in jeans and sneakers, makes his way through the crowd, shaking hands, his winsome smile comfortably affixed. We’re here for a recurring comedy show that’s offered to members of Bilt, the loyalty program and payments platform for renters that Jain founded in 2019. As usual, the show sold out—thr

The internet of agents is rising fast, and publishers are nowhere near ready

Imagine you owned a bookstore. Most of your revenue depends on customers coming in and buying books, so you set up different aspects of the business around that activity. You might put low-cost “impulse buy” items near the checkout or start selling coffee as a convenience. You might even partner with publishers to put displays of popular bestsellers in high-visibility locations in the story to drive sal

How ‘Subway Surfers’ has dominated mobile gaming for over a decade

For 13 years, Subway Surfers’ download rate has been consistent: about one million new installs every single day. 

Half of those downloads come from users upgrading to new devices. The other half comes from children aging into phone usage, and users in less developed countries reaching a level of affluence that allows them to purchase their first smartphones. This steady influx of players has made Subway Surfers the most downloaded mobile game of all time, wi

A new Roblox study shows how longer suspensions help curb bad behavior on platforms

Misbehavior on digital platforms can be tricky to manage. Issue warnings, and you risk not deterring bad behavior. Block too readily, and you might drive away your user base and open yourself to accusations of censorship. But a new study, presented at the Conference on Human Factors in Computing Systems, suggests a more effective path forward.

Researchers at Northeastern University and Roblox conducted two large-scale

5 must-use Microsoft Edge browser features to save time and money

You’d be forgiven for forgetting that there was a time when Microsoft Edge was basically the web browser that opened when you accidentally clicked a link that didn’t default to opening in Chrome or Firefox.

But something shifted in 2020 when Microsoft switched Edge’s digital drivetrain to Chromium, the technology that powers the Google Chrome browser and others like it.

Edge suddenly shed its awkward skin and emerged as a genuinely competent—nay, pleasant—browsing experie

Podle nové teorie je čas trojrozměrný a prostor je jenom stínem jeho slávy

Geofyzik s českými kořeny Gunther Kletetschka přetavil starší matematické představy o 3D času do podoby testovatelné teorie. Pokud má pravdu, žijeme ve světě šesti dimenzí, jehož strukturu primárně vytvářejí tři dimenze času. Byla by to zajímavá změna oproti klasickému časoprostoru. http://www.osel.cz/14127-podle-nove-teorie-je-cas-trojrozmerny-a-prostor-je-jenom-stinem-jeho-slavy.html

Umelá krv opäť ide do klinických testov, vypadá to nádejne

Umelá krv, ktorú by bolo možné jednoducho skladovať a prepravovať aj vo veľkých množstvách, by bola veľkým prínosom nielen pre armády a pre medicínu katastrof. Po dlhých rokoch výskumu však doposiaľ výsledné produkty nikdy nenaplnili očakávania. Nové riešenia so zapuzdreným hemoglobínom sú však veľmi sľubné. http://www.osel.cz/14126-umela-krv-op-t-ide-do-klinickych-testov-vypada-to-nadejne.html

Those security codes you ask to receive via text leave your accounts vulnerable. Do this instead

Do you receive login security codes for your online accounts via text message? These are the six- or seven-digit numbers sent via SMS that you need to enter along with your password when trying to access your bank accounts, health records, online photos, and more. This type of security is known as multifactor authentication (MFA) and is designed to keep your account secure even if someone knows your password. Without the additional security code, bad actors can’t gain access to your data. Or

This is the best online file converter—and it’s totally free

We were supposed to be finished with files by now.

For years, tech companies (well, certain tech companies) tooted their horns about a future in which files didn’t matter. You don’t even need a file manager of any sort, they told us—and, in fact, we won’t even let you see the file system on your devices at all. Just tap-a-tap-tap, don’t worry, be happy. Right?

Yeah—not so much. Here in the year o’ 2025, files absolutely still matter. Whether you

Astroworld is back in the spotlight and survivors are sharing haunting stories on TikTok

Astroworld is back in the news, and social media has some thoughts.

In November 2021, a deadly crowd surge at Travis Scott’s Astroworld music festival claimed the lives of 10 people. The then-annual event, held in the rapper’s hometown of Houston, became one of the worst concert tragedies in U.S. history. Now it’s the subject of the new Netflix documentary Trainwr

What is ‘office chair butt’? TikTok’s viral term for a real health problem

Rather than the Sunday scaries or toxic bosses, employees have unlocked a new workplace fear: office chair butt.

While not a new concern, the term has resurfaced on TikTok to describe how sitting for long stretches affects the look of your behind—what medical professionals call atrophy of your gluteal muscle group.

“A lack of conditioning in your gluteus maximus and surrounding tissue leads to weakness, making it build up fat tissue and appear flatter or saggy,” occupatio
