Communication satellites and flying antenna platforms can contribute to the comprehensive and resilient operation of global mobile networks of the fifth and sixth generation (5G, 6G). However, as large parts of the millimeter wave (mmW) frequency spectrum must be reallocated for this purpose, more powerful radio frequency technologies are required for satellite communication in the Ka- (27–31 GHz), Q- (37.5–42.5 GHz) and W-band (71–76 GHz).

USB-C? More like USB-kawaii.

But will it have any real impact?

On Sept. 13, 1944, researchers subjected a Bell P-39L Airacobra to frigid temperatures and a freezing water spray in the National Advisory Committee for Aeronautics (NACA)'s new Icing Research Tunnel (IRT) to study inflight ice buildup. Since that first run at the Aircraft Engine Research Laboratory (now NASA's Glenn Research Center) in Cleveland, the facility has operated on a regular basis for 80 years and remains the oldest and one of the largest icing tunnels in the world.

New research introduces a method to improve the accuracy and speed of dynamic emotion recognition using a convolutional neural network (CNN) to analyze faces. The work undertaken by Lanbo Xu of Northeastern University in Shenyang, China, could have applications for mental health, human-computer interaction, security, and other areas.

Millions of Brazilians, including the president, have flocked to social media platforms such as Threads or Bluesky, where Portuguese has become the most spoken language in the few days since Elon Musk's X was shut down in the country.

Across all species, critical skills are passed on from parents to offspring through communication. Researchers at the University Hospital Bonn (UKB) and the Researchers at the University of Bonn showed that effective communication relies on how both the sender and receiver represent information. Their study reveals how this process underlies training efficacy and task performance. Their results have been published in the journal Nature Communications.

A standoff between a Brazilian Supreme Court judge and Elon Musk intensified Thursday as the billionaire's Starlink company said its assets had been frozen in the country amid a feud over the fate of his social media platform X.

iPhone juggernaut Apple is in talks to invest in OpenAI, the creator of ChatGPT and the biggest name in generative artificial intelligence, a news report said Thursday.

Researchers at the Department of Instrumentation and Applied Physics (IAP), Indian Institute of Science (IISc) and collaborators have designed a new supercapacitor that can be charged by light shining on it. Such supercapacitors can be used in various devices, including streetlights and self-powered electronic devices such as sensors.

Prof. Kaichen Xu and his coworkers from Zhejiang University have developed a novel method to integrate sensor systems directly into engineering thermoplastics using laser technology. Their breakthrough offers the potential for improved safety and extended service life of critical equipment across various industries, including aerospace, automotive, health care, and transportation.

Deep learning (DL) has significantly transformed the field of computational imaging, offering powerful solutions to enhance performance and address a variety of challenges. Traditional methods often rely on discrete pixel representations, which limit resolution and fail to capture the continuous and multiscale nature of physical objects. Recent research from Boston University (BU) presents a novel approach to overcome these limitations.

Verizon is buying Frontier Communications in a $20 billion deal to strengthen its fiber network.

Li-ion batteries can present major hazards, with the notion of safety based on narrow criteria. A meta-analysis of thermal runaway gas emissions by Sheffield researchers, published in the Journal of Energy Storage improves understanding and highlights the need for a broader analysis of risks.

German luxury carmaker BMW said Thursday it aimed to mass produce its first hydrogen-powered car in 2028, using fuel cell technology jointly developed with Japan's Toyota.

Inga Strümke does not believe artificial intelligence will take over the world with killer robots, but it might kill your spark. This is an area that needs rules, and Europe is about to get them.

France's newest nuclear reactor, plagued by massive delays and cost overruns, shut itself down automatically Wednesday just a day after starting up for the first time.

A new ultra-small electronic nose (e-nose) that operates on ultralow power opens up possibilities for applications in various fields, such as air quality monitoring, health diagnostics, food safety, and environmental protection.

A wearable 'smart' choker for speech recognition has the potential to redefine the field of silent speech interface (SSI), say researchers—thanks to embedded ultrasensitive textile strain sensor technology.

Australia's federal government has today launched a proposed set of mandatory guardrails for high-risk AI alongside a voluntary safety standard for organizations using AI.
