Turning car exhausts into power: New method transforms carbon nanoparticles from emissions into renewable energy catalysts

We have developed a breakthrough method to convert carbon nanoparticles (CNPs) from vehicular emissions into high-performance electrocatalysts. This innovation provides a sustainable approach to pollution management and energy production by repurposing harmful particulate matter into valuable materials for renewable energy applications. Our work, published in Carbon Neutralization, addresses both environmental challenges and the growing demand Read more about Turning car exhausts into power: New method transforms carbon nanoparticles from emissions into renewable energy catalysts[…]

Why Can’t We Screenshot Frames From DRM-Protected Video on Apple Devices? – or on Android in some apps?

Apple users noticed a change in 2023, “when streaming platforms like Netflix, HBO Max, Amazon Prime, and the Criterion Channel imposed a quiet embargo on the screenshot,” noted the film blog Screen Slate: At first, there were workarounds: users could continue to screenshot by using the browser Brave or by downloading extensions or third-party tools Read more about Why Can’t We Screenshot Frames From DRM-Protected Video on Apple Devices? – or on Android in some apps?[…]

These buildings use batteries made of ice to stay cool and save money

Thousands of buildings across the United States are staying cool with the help of cutting-edge batteries made from one of the world’s simplest materials: ice. When electricity is cheap, the batteries freeze water. When energy costs go up, building managers turn off their pricey chillers and use the ice to keep things cool. A typical Read more about These buildings use batteries made of ice to stay cool and save money[…]

Trump’s Defense Secretary Hegseth Orders Cyber Command to ‘Stand Down’ on All Russia Operations

The order reportedly does not apply to the National Security Read more about Trump’s Defense Secretary Hegseth Orders Cyber Command to ‘Stand Down’ on All Russia Operations[…]

“Cool” years are now hotter than the “warm” years of the past: tracking global temperatures through El Niño and La Niña

Temperatures, as defined by “climate”, are based on temperatures over longer periods of time — typically 20-to-30-year averages — rather than single-year data points. But even when based on longer-term averages, the world has still warmed by around 1.3°C.3 But you’ll also notice, in the chart, that temperatures haven’t increased linearly. There are spikes and Read more about “Cool” years are now hotter than the “warm” years of the past: tracking global temperatures through El Niño and La Niña[…]

Lenovo has a convertable T series laptop – with mouse dot

[…] The ThinkPad T14s 2-in-1 is by far the most interesting of the bunch, with a new convertible body that’s similar to Lenovo’s Yoga laptops, and supports the magnetic Yoga Pen stylus. The laptop comes with up to a 14-inch, 400-nit WUXGA touch display, and inside, you can get up to a Intel Core Ultra Read more about Lenovo has a convertable T series laptop – with mouse dot[…]

The Lenovo Solar PC Concept feels like a device whose time has come

You might be surprised to learn that the first laptop with built-in solar panels is nearly 15 years old. But to me, the bigger shock is that with all the recent advancements in photovoltaic cells, manufacturers haven’t revisited this idea more often. But at MWC 2025, Lenovo is changing that with its Yoga Solar PC Read more about The Lenovo Solar PC Concept feels like a device whose time has come[…]

PeerAuth – easy way to authenticate a real person

Machine learning has become more and more powerful, to the point where a bad actor can take a photo and a voice recording of someone you know, and forge a complete video recording. See the “OmniHuman-1” model developed by ByteDance: discussion on X ByteDance’s paper   Bad actors can now digitally impersonate someone you love, Read more about PeerAuth – easy way to authenticate a real person[…]
