    Diffusion dynamics play an essential role in regulating stem cells and tissue development

    Original @ Phys.org – latest science and technology news stories Gradients of molecular signaling factors play an essential role in numerous events in embryonic development, from patterning limb and organ formation to the intricate shaping of the brain and neuroanatomical architecture. These gradients are a consequence of diffusion dynamics in tissues, and newly published work describes two vital aspects of these diffusion processes in tissue development—first, the influence of molecular diffusion gradients on stem cell signaling pathways is described in detail, including a summary of recent discoveries in how gas and nutrient concentrations can influence stem cell potency, differentiation, and metabolism. Secondly, the paper describes novel applications of diffusion equations to model concentration gradients of nutrients and signaling factors in three-dimensional (3D) tissue constructs under a variety of conditions, including with or without cellular metabolism of the diffusing substance.

    How to run faster, smarter AI apps on smartphones

    Original @ KurzweilAI » News When you use smartphone AI apps like Siri, you’re dependent on the cloud for a lot of the processing — limited by your connection speed. But what if your smartphone could do more of the processing directly on your device — allowing for smarter, faster apps? MIT scientists have taken a step in that direction with [...] [...]

    Projecting a visual image directly into the brain, bypassing the eyes

    Original @ KurzweilAI » News Imagine replacing a damaged eye with a window directly into the brain — one that communicates with the visual part of the cerebral cortex by reading from a million individual neurons and simultaneously stimulating 1,000 of them with single-cell accuracy, allowing someone to see again. That’s the goal of a $21.6 million DARPA award to [...] [...]
