This study explores liquid metal-based flexible three-dimensional integrated circuits (3D ICs), highlighting their exceptional conductivity, stretchability, and biocompatibility. By leveraging 3D printing and advanced fabrication methods, researchers achieve high-resolution, scalable circuits for wearable and biomedical applications. The work addresses key challenges such as oxidation, interconnect stability, and multilayer integration, paving the way for next-generation flexible electronics.

Despite the popularity of augmented reality, AR wearable technologies haven’t gained traction due to the weight and bulk associated with batteries and electronic components, and the suboptimal computational power, battery life and brightness of the devices. A team of researchers recently improved the practicality of light-receiving AR glasses by increasing the angle of incidence light capable of producing an adequate projected AR image from five degrees to roughly 20-30 degrees.

Kyoto, Japan -- Explosions in the sky and explosions on land are literally worlds apart. A supernova and a land mine explosion don't seem like they would have much in common. But at the fine level, their mechanisms are not so different: the so-called cell structure appears at the smallest scale, which provides the most important criterion in predicting the success or failure of terrestrial detonation in a land-mine explosion.

Terrestrial and astrophysical detonations are basically dictated by the same theories for their time-averaged characteristics. Terrestrial cell-based theories, however -- such as those that explain a land mine explosion -- have not yet been applied as criteria for astrophysical detonation.

Motivated by the potential of this theoretical analogy, an interdisciplinary research team of engineers and astrophysicists at Kyoto University recently joined together to better understand how type Ia supernovae explode.

A team of Tufts University researchers created Morpho, an open-source programmable environment that enables researchers and engineers to conduct shape optimization and design for soft materials. Applications can be for anything from artificial hearts to robot materials that mimic flesh and soft tissue.
