Recent advancements at the Department of Energy's Oak Ridge National Laboratory show that 3D-printed metal molds offer a faster, more cost-effective and flexible approach to producing large composite components for mass-produced vehicles than traditional tooling methods.... Read more

Scientists have created the first soft robots that can walk straight out of the machines that make them.... Read more

Researchers at the University of Osaka have developed an energy-efficient and high-precision measurement system leveraging the inherent similarity between waveforms generated by the same type of signal source.... Read more

From smartphones and TVs to credit cards, technologies that manipulate light are deeply embedded in our daily lives, many of which are based on holography. However, conventional holographic technologies have faced limitations, particularly in displaying multiple images on a single screen and in maintaining high-resolution image quality.... Read more

Modern computer chips generate a lot of heat—and consume large amounts of energy as a result. A promising approach to reducing this energy demand could lie in the cold, as highlighted by a new Perspective article by an international research team coordinated by Qing-Tai Zhao from Forschungszentrum Jülich. Savings could... Read more

To guarantee high data security, encryption must be unbreakable while the data remains rapidly and easily readable. A novel strategy for optical encryption/decryption of information has now been introduced in the journal Angewandte Chemie by a Chinese research team. It is based on compounds with carefully modulated luminescent properties that... Read more

President Donald Trump announced a plan to build a missile defense system, called the Golden Dome, on May 20, 2025. The system is intended to protect the United States from ballistic, cruise and hypersonic missiles, and missiles launched from space.... Read more

A new artificial intelligence system pinpoints the origin of 3D printed parts down to the specific machine that made them. The technology could allow manufacturers to monitor their suppliers and manage their supply chains, detecting early problems and verifying that suppliers are following agreed upon processes....

Humans naturally learn by making connections between sight and sound. For instance, we can watch someone playing the cello and recognize that the cellist's movements are generating the music we hear.... Read more

A research team has developed the world's first Pixel-Based Local Sound OLED technology. This breakthrough enables each pixel of an OLED display to simultaneously emit different sounds, essentially allowing the display to function as a multichannel speaker array. The team successfully demonstrated the technology on a 13-inch OLED panel, equivalent... Read more

Sound can do more than just provide a nice beat. Sound waves have been used for everything from mapping the seafloor to breaking apart kidney stones. Thanks to a unique material structure, researchers can now move and position objects underwater without ever touching them directly.... Read more

Scientists at the University of Surrey have made a breakthrough in eco-friendly batteries that not only store more energy but could also help tackle greenhouse gas emissions. Lithium–CO2 "breathing" batteries release power while capturing carbon dioxide, offering a greener alternative that may one day outperform today's lithium-ion batteries.... Read more

A research team has developed an adaptable three-dimensional (3D) display panel using circularly polarized luminescence (CPL) devices. Their research is published in Science Advances, and was led by Prof. Zhuang Taotao and Prof. Yu Shuhong from the University of Science and Technology of China (USTC).... Read more

Imagine wearing a T-shirt that measures your breathing or gloves that translate your hand movements into commands for your computer. Researchers at ETH Zurich, led by Daniel Ahmed, Professor of Acoustic Robotics for Life Sciences and Healthcare, have laid the foundations for just such smart textiles.... Read more
