In recent years, many engineers have been trying to develop hardware components that could emulate the functions of various biological systems, including synapses, the human skin and nerves. These bio-inspired systems include what are referred to as artificial nerves, systems designed to emulate the role of nerves in the body of humans and other animals.
Artificial nerves could be useful for a wide range of applications, ranging from systems for repairing damaged nerves to brain-computer interfaces, highly precise sensors and other advanced electronics. So far, however, the engineering of nerve-inspired systems that operate at biologically compatible frequencies and realistically replicate the function of nerves has proved challenging.
Researchers at Xi’an Jiaotong University in China and Technical University of Munich recently developed a new high-frequency artificial nerve with a unique design that optimizes the transport of ions and electrons, while also rapidly responding to signals and retaining charge-related information. This nerve-inspired system, introduced in a paper published in Nature Electronics, is based on homogenously integrated organic electrochemical transistors.
This compares some of the ringworlds, centrifuges, space stations, and ships that use spin to make gravity. It also try’s to show how the variables of artificial gravity are used to make centripetal acceleration into spin gravity.

A new method inspired by coral reefs can capture carbon dioxide from the atmosphere and transform it into durable, fire-resistant building materials, offering a promising solution for carbon-negative construction.
The approach, developed by USC researchers and detailed in a study published in npj Advanced Manufacturing, draws inspiration from the ocean’s coral reefs’ natural ability to create robust structures by sequestering carbon dioxide. The resulting mineral-polymer composites demonstrate extraordinary mechanical strength, fracture toughness and fire-resistance capabilities.
“This is a pivotal step in the evolution of converting carbon dioxide,” said Qiming Wang, associate professor of civil and environmental engineering at the USC Viterbi School of Engineering. “Unlike traditional carbon capture technologies that focus on storing carbon dioxide or converting it into liquid substances, we found this new electrochemical manufacturing process converts the chemical compound into calcium carbonate minerals in 3D-printed polymer scaffolds.”

A new technology has been developed that enables the manufacturing of thin films, which typically require complex processes, using only water and oil in just one minute. Professor Kang Hee Ku and her research team from the School of Energy and Chemical Engineering at UNIST announced their novel process for creating catalytic thin films using oil droplets dispersed in water.
The developed technology involves a process in which nanomaterial precursors attached to the surface of oil droplets float to the surface of the water, where they assemble into a thin film. When hydrogen peroxide is added, it decomposes due to the thin film precursors, producing gas bubbles that cause the precursors to be lifted and assembled on the water surface within one minute.
This process allows for precise control of the thin film thickness, adjustable from 350 μm, and enables the synthesis of thin films covering an area of up to 100 cm² using various raw materials. The resulting thin films exhibit a porous structure with a high surface area, featuring exceptional mechanical strength and flexibility.
A research team led by Colorado State University has achieved a new milestone in 3D X-ray imaging technology. The scientists are the first to capture high-resolution CT scans of the interior of a large, dense object—a gas turbine blade—using a compact, laser-driven X-ray source.
The findings, published in Optica, describe the science and engineering behind this new radiographic imaging capability and its potential benefits for a range of industries, from aerospace to additive manufacturing.
The project is a years-long collaboration between researchers at CSU’s Departments of Electrical and Computer Engineering and Physics and Los Alamos National Laboratory, with participation from AWE in the U.K.
Extracellular vesicles can be designed to serve as delivery platforms for gene therapy. This Review discusses the application and engineering of extracellular vesicles for different gene-therapy modalities, outlining crucial steps to advance this technology into the clinic.
A research team at UNIST has identified the causes of oxygen generation in a novel cathode material called quasi-lithium and proposed a material design principle to address this issue.
Quasi-lithium materials theoretically enable batteries to store 30% to 70% more energy compared to existing technologies through high-voltage charging of over 4.5V. This advancement could allow electric vehicles to achieve a driving range of up to 1,000 km on a single charge. However, during the high-voltage charging process, oxygen trapped inside the material can oxidize and be released as gas, posing a significant explosion risk.
The research team, led by Professor Hyun-Wook Lee in the School of Energy and Chemical Engineering, discovered that oxygen oxidizes near 4.25V, causing partial structural deformation and gas release.

Dr. Clément Vidal joins John Michael Godier to discuss his new paper on the Spider Stellar Engine, a hypothetical form of stellar propulsion using binary pulsar systems. The conversation explores how such systems could serve as **technosignatures**, the philosophy of post-biological civilizations, and the potential for advanced beings to manipulate entire stars or even create new universes.
