Diffusion happens naturally and so does not require energy. Substances like oxygen, carbon dioxide and glucose move in and out of cells by diffusion. If I spray a little perfume over here, ...

In contrast, DT-MRI exploits the effects of tissue microstructure on the diffusion of water to generate endogenous tissue contrast scans. The motion of water molecules in tissues varies between ...

The findings were published in Science Robotics, showcasing the potential of integrating biological systems with robotic frameworks. The biohybrid hand operates using “MuMuTAs” (multiple muscle tissue ...
