A research team led by researchers at Chalmers University of Technology in Sweden, has, for the first time, successfully decoded leg movements directly from the remaining nerves in people with above-knee amputations. Using novel implantable neurotechnology and an AI method based on the nervous system’s own “language”, the researchers could do what was previously impossible and interpret detailed movements – even the will to wiggle toes. This technology opens the way to future leg prostheses that feel and act more like a natural part of the body.

Cells in our bodies produce RNA based on genetic information stored in DNA, and RNA serves as a blueprint for making proteins. Researchers at our university have discovered a new phenomenon: removing 'circular RNA' that accumulates in cells as we age can slow down aging and extend lifespan. This study provides crucial clues for uncovering the principles of aging and developing treatment strategies for related diseases.

Cell spheroids are some of the most realistic models available for drug testing, disease research, and regenerative medicine. However, their dense structures limit cell survival and function — halting their production at scale. A new assembly method proposed by researchers from Penn State, detailed in a paper recently published in Advanced Science, facilitates spheroids that can rapidly self-assemble or “snowball” in size, while still allowing life-supporting oxygen to reach the cells inside.

A newly identified disease affecting corn and sorghum can closely resemble iron deficiency, potentially leading farmers to apply costly nutrient treatments that do not address the underlying problem. New research published in Plant Health Progress documents the discovery and identification of a bacterial pathogen responsible for the symptoms.
