During a thunderstorm, you can feel rain pouring, see lightning flashing and hear wind howling. Unlike these phenomena, the Aurora Borealis cannot be heard or felt because it occurs through the earth's magnetic field's invisible influence, noticeable only if you seek it out.

A team of sustainable energy engineers at The Hong Kong University of Science and Technology, working with a pair of colleagues from the GD MIDEA Air-Conditioning Equipment Co., LTD., in China, has developed a personalized cooling apparatus to replace traditional air-conditioning.

Imagine a future where internet connections are not only lightning-fast but also remarkably reliable, even in crowded spaces. This vision is rapidly approaching reality, thanks to new research on terahertz communications technologies. These innovations are set to transform wireless communication, particularly as communications technology advances toward the next generation of networks, 6G.

On a remote patch of the windy, frozen Beaufort Sea north of Alaska, engineers from NASA's Jet Propulsion Laboratory in Southern California huddled together, peering down a narrow hole in a thick layer of sea ice. Below them, a cylindrical robot gathered test science data in the frigid ocean, connected by a tether to the tripod that had lowered it through the borehole.

原子力発電所の適切な機能を監視するために不可欠な、特定の放射性ガスに対して優れた感度でリアルタイム測定を可能にするシンチレーションエアロゲルが、CNRS、クロード・ベルナール・リヨン大学の物理学者、化学者、気象学者のグループによって開発されました。、CEA、ENS de Lyon。

The cost effectiveness of wind farms could be significantly improved by reducing the speed of wind turbines that are clustered together, which could improve their longevity and also reduce noise pollution.

洪水を防ぐために数十年から100年前に設計された国内の雨水インフラの多くは、世界中で増加している悪天候時に洪水を悪化させる可能性があることが、ミシガン大学主導の新たな研究で実証された。

Researchers at Tohoku University have successfully increased the capacity, lifetime durability, and cost-effectiveness of a capacitor in their pursuit of a more power-efficient future. The research is published in the journal ACS Applied Materials & Interfaces.

If only techno-optimists get to test AI tools, the results simply aren't good enough. This is where Tesla made a big mistake—a lesson that the health sector will do well to learn.

The UK on Tuesday said it had awarded a record 131 new green infrastructure projects in a single auction, including plans for Europe's two biggest offshore windfarms.

A new study has found that U.K. hotels and restaurants using humanlike service robots can make solo guests feel more comfortable in engaging with these robots by providing comfortable ambient conditions—including lighting, scents and sounds—and adding local cues like British flag designs on the robot's body.

Wireless sensing and communication have become integral components of modern life. Among them, the key technology of direction-of-arrival (DOA) estimation, which utilizes array signal processing techniques to measure the angular direction of RF signals, has been widely applied in both civilian and military domains.

A French ship navigating past New York City to harbor laden with Champagne, Cognac and jam under sail might recall a long-forgotten age of wind navigation.

Analyzing and simulating fluid flow is a challenging mathematical problem that impacts various scenarios, including video game engines, ocean current modeling and hurricane forecasting. The core of this challenge lies in solving the Navier–Stokes equations, a set of classical equations that describe fluid dynamics.

General AI systems, like OpenAI's GPT, depend on large amounts of training data to improve model accuracy and performance. Research or medical AI applications, which often lack both training data and computing power, can leverage a new model designed to improve the efficiency, relevance and accuracy of AI outputs for more specialized scenarios.

In recent years, the Massively Parallel Computation (MPC) model has gained significant attention. However, most distributed and parallel graph algorithms in the MPC model are designed for static graphs. Dynamic graph algorithms can deal with graph changes more efficiently than the corresponding static graph algorithms. Moreover, a few parallel dynamic graph algorithms (such as the graph connectivity) in the MPC model have been proposed and shown superiority over their parallel static counterparts. However, there are no existing dynamic all-pairs shortest paths (APSP) algorithms working in the MPC model.

Scientists at the Daegu Gyeongbuk Institute of Science and Technology have created a fuel cell catalyst made from platinum and magnesium. The new catalyst, which uses the world's first platinum–magnesium alloy nanoparticles, is expected to be both highly efficient and durable, potentially offering significant improvements in clean energy technology.

What made you decide to go solar? Was it a sober assessment of the return on investment? Did you want to cut your power bills? Did you want to do your bit on climate change?

Fuel cells are energy-conversion solutions that generate electricity via electrochemical reactions without combustion, thus not contributing to the pollution of air on Earth. These cells could power various technologies, ranging from electric vehicles to portable chargers and industrial machines.
