Meet Carvey Ehren Maigue, a Filipino engineering student who developed a revolutionary solar panel made from discarded fruits and vegetables. His invention, called AuREUS, captures ultraviolet light instead of relying on direct sunlight—meaning it can generate clean energy even on cloudy days or in shaded spaces. It uses luminescent particles from food waste to absorb UV rays and convert them into visible light, which is then harnessed by solar strips.

This breakthrough could change the future of urban solar power. Instead of bulky rooftop installations, AuREUS panels can be mounted on windows or walls, bringing sustainable energy generation into cities and indoor environments. For his game-changing innovation, Maigue won the prestigious 2020 James Dyson Sustainability Award, showing how waste can literally become power.

China has officially begun mass production of a revolutionary type of AI chip that breaks away from traditional binary processing.

Developed by researchers at Beihang University and led by Professor Li Hongge, this chip employs a Hybrid Stochastic Number (HSN) architecture, which integrates both binary and stochastic (probability-based) logic.

This allows it to process data in a way that is more efficient, fault-tolerant, and better suited for certain AI and edge computing tasks compared to conventional binary chips.

What makes this development particularly noteworthy is its strategic design choices.

The chip is manufactured using mature 110 nm and 28 nm processes—technologies that do not require the most advanced lithography tools like EUV (Extreme Ultraviolet Lithography), which are heavily restricted due to international sanctions.

This move effectively allows China to bypass some of the global constraints imposed on its semiconductor sector.

The chip has already been deployed in practical applications such as aviation systems, industrial control equipment, and intelligent displays, showcasing its versatility and readiness for real-world use.

In essence, this "non-binary" AI chip is not just a technical innovation, but also a symbol of China’s strategic push toward semiconductor independence.

It aims to overcome the "power wall" (reducing energy consumption) and the "architecture wall" (ensuring compatibility with existing chip infrastructure), which are two major hurdles in the chip industry today.

While the technology is still in early stages and awaits broader third-party evaluation, its mass production marks a significant milestone that could influence the future direction of AI hardware design globally.

A Filipino engineering student, Carvey Ehren Maigue, developed an innovative solar panel called AuREUS, which is made from recycled food waste—specifically rotting fruits and vegetables.

Unlike traditional solar panels that need direct sunlight, this panel works by capturing ultraviolet (UV) light, allowing it to generate electricity even on cloudy days or in shaded areas.

The technology uses luminescent particles from plant waste that absorb UV rays and re-emit them as visible light, which is then harvested by photovoltaic strips at the panel’s edges.

This makes it ideal for use on walls or windows in cities, where sunlight can be inconsistent.

Carvey’s invention earned him the 2020 James Dyson Sustainability Award, recognizing its potential to revolutionize solar energy by making it more adaptable, environmentally friendly, and accessible—especially in urban or low-light environments.

In a major breakthrough, scientists have revised the length of a day on Uranus—and it’s now 28 seconds longer than we thought.

Thanks to over a decade of data from the Hubble Space Telescope, researchers have calculated that a full Uranian day lasts exactly 17 hours, 14 minutes, and 52 seconds.

That may sound like a tiny change, but for planetary scientists, it’s a big deal.

Until now, the only direct measurements came from NASA’s Voyager 2 flyby in 1986, which left lingering uncertainties—especially around Uranus’ magnetic poles. Those outdated rotation estimates made it nearly impossible to accurately track how the planet's magnetosphere behaves over time.

To solve this, a team led by Laurent Lamy (Paris Observatory) analyzed Hubble’s ultraviolet observations from 2011 to 2022, tracking auroras caused by solar wind slamming into Uranus’ magnetic field.

By following those glowing signals, they were able to pinpoint the magnetic poles and determine Uranus’ rotation period with unprecedented precision—even more accurately than we know Jupiter’s.

That’s especially impressive considering Uranus spins almost completely sideways, making these measurements incredibly tricky.

This refined rotation rate is crucial—it will help scientists build better models of Uranus’ interior, magnetic field, and future missions, including NASA’s upcoming plans to explore the ice giant in detail.
