A new self-rectifying memristor array with exceptional stability and precise multi-state regulation capabilities has been developed, laying a hardware foundation for efficient neuromorphic computing. When integrated with a simulated annealing algorithm, it achieves fast and accurate image restoration, showcasing promising application prospects.

In the International Journal of Extreme Manufacturing, researchers at Jilin University now report a way to measure the electrical conductivity of such fluids using volumes as small as 50 nanoliters. Their device is an optical fiber probe no thicker than a human hair. It is designed for stable and real-time measurements and is largely unaffected by temperature or pH, two factors that often distort readings in biological environments.

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function depend on exquisitely ordered myofibers, all aligned in precise directions that vary from one muscle to another. Reproducing that internal order has proved far harder than shaping muscle tissue into the right external form.

In the International Journal of Extreme Manufacturing, a research team from Xi'an Jiaotong University has now found a way to solve both problems at once. By using electric forces during the electrohydrodynamic bioprinting process, they have created living muscle tissues whose cells naturally line up just as they do in the human body, showing how electric forces can be used not just to precisely bioprint tissue, but to quietly instruct cells how to organize themselves.

ETH researchers have developed a novel hydrogel consisting mainly of water and a polymer network.

Using laser light, the researchers can very quickly solidify the hydrogel into a material with microscopically fine structures so that bone-forming cells can colonise it 

This material has the potential to be used as a bone implant in the future, enhancing the healing process of bone fractures.

A study from the Research Center for Materials Nanoarchitectonics (MANA) has uncovered a theoretical mechanism showing how the electronic band structures of strongly correlated insulators can be reshaped by spin and charge perturbations, opening up new possibilities for electronics with tunable band structures.

A new culprit: While billions of dollars have been spent targeting Amyloid beta (Aβ) in Alzheimer’s patients, a newly reevaluated, shorter peptide known as P3 forms toxic clumps faster than Aβ and may also contribute to the disease.

Explaining stalled progress: The overwhelming focus on Aβ, and the erroneous assumption that P3 is harmless and water-soluble, may explain why current Alzheimer’s treatments show limited success and fail to stop the disease’s progression.
