Over the past year, artificial intelligence has made a significant impact on the world. While most of us have noticed the advancements in text and image tools like ChatGPT and Midjourney, a deeper revolution is happening beneath the surface.

Future generation networks must provide high transmission speeds and flexible coverage. One way to do this is through networks of unmanned aerial vehicles, or drones. They operate in the millimeter wave range. But the use of a wide range of antennas and higher losses during signal propagation are disadvantages. All this requires energy, and drone batteries have limited capacity.

The maglev train represents a type of modern urban rail transit transportation tool, boasting many technical advantages such as low noise, green environmental protection, small turning radius, good stability and high comfort. These advantages are due to the suspension mode of the train.

Uncertainty estimation is critical to improving the reliability of deep neural networks. A research team led by Aydogan Ozcan at the University of California, Los Angeles, has introduced an uncertainty quantification method that uses cycle consistency to enhance the reliability of deep neural networks in solving inverse imaging problems.

The use of dual metal sulfides, specifically ZnS/CuS, shows marked improvement in electrochemical stability and performance when included in the design of flexible lithium-ion capacitors over the use of transition metal sulfides and carbon fiber materials.

The image spoke for itself. University at Buffalo computer scientist and deepfake expert Siwei Lyu created a photo collage out of the hundreds of faces that his detection algorithms had incorrectly classified as fake—and the new composition clearly had a predominantly darker skin tone.

Statewide broadband adoption remains high with 91% of households in California enjoying high-speed internet access at home, according to new survey results released today by USC, the California Emerging Technology Fund and the California Department of Technology.

Researchers from RUDN University have proposed a new scheme for the Internet of Things network. It uses flying drones that process data instead of cloud data centers, which speeds up the network. The results were published in Drones.

Apple's iPhone for the first time became the world's biggest selling smartphone after rival Samsung's 12-year run as leader, data showed.

Ryanair on Tuesday welcomed improved quality controls at US aircraft manufacturer Boeing and announced its own enhanced checks, after a major safety issue.

The demand for high-quality wireless communications is growing along with the number of applications and devices. One way to provide such a network is to use a system of drone routers. Such a system would be useful, for example, in situations where it is necessary to quickly and simultaneously provide a signal to a large area—during natural disasters, large-scale incidents, and public events.

To prevent aircraft stalls, engineers have long studied the flow of air over airfoils such as airplane wings to detect the angles when flow separation occurs. Recently, a team of researchers at Shanghai Jiao Tong University, including Xi-Jun Yuan and Zi-Qiao Chen, investigated the use of quantum computing in connection with machine learning as a more accurate way of solving such problems.

A team of AI experts at Anthropic, the group behind the chatbot Claude, has found that LLMs can be exploited to engage in deceptive behavior with general users. They have published a paper describing their research into the problem on the arXiv preprint server.

While cyber-attacks on banks, utilities and media platforms may grab the most attention, the hacking of the British Library has led to warnings that academia has become an easy target.

Organic electronics—electronics where the active material is carbon-based—are making possible diverse new technologies ranging from sensors for monitoring cannabinoid levels in cannabis plants to lightweight, bendable solar panels. Real-world applications could result in solar panels you roll up and take with you on your next camping trip, or cannabis producers knowing the optimal time to harvest plants.

A breakthrough technology has been developed that enables the production of green hydrogen in a more cost-effective and environmentally friendly manner, bringing us closer to a carbon-neutral society by replacing expensive precious metal catalysts.

Materials and objects could take on different shapes by themselves through a method developed at KTH Royal Institute of Technology. Breakthrough tests showed how microscale melting and cooling of a wide range of materials—such as plastics and metals—can be manipulated to reorganize their mass and form new shapes.

"Soft robots," medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism—thanks to a metal-free magnetic gel developed by researchers at the University of Michigan and the Max Planck Institute for Intelligent Systems in Stuttgart, Germany.

Houston's water and wastewater system could be more resilient with the development of hybrid urban water supply systems that combine conventional, centralized water sources with reclaimed wastewater, according to a study by Rice University engineers now published in Nature Water.

German car rental group Sixt said Tuesday it has agreed to buy up to 250,000 cars from automaker Stellantis in a "multi-billion euro" deal that includes electric vehicles.
