项目摘要

Large, three-dimensional cell colonies grown inexpensively using simple raw materials could be made into cheap, energy-efficient computers. A fundamental challenge in using living cells for computing is that computation by cells is error prone, and cells divide, die and reorganize inside a cell culture, making it difficult to maintain a defined architecture. This research will explore the design of yeast cell-based computing systems inspired by how computing is performed by the animal brain cells. To develop new knowledge at the intersection of electronics, computing and biology will require a new generation of students familiar with each of these areas who can work in collaborative teams. Building on work with organizations including the Freshman Research Initiative at UT Austin and Women in Science and Engineering at JHU, the PIs will develop programs to allow groups of undergraduate researchers to engage in long term research programs in which students have the opportunity to perform independent investigations as part of collaborative, inter-university teams.This project will combine ideas from computer architecture and systems neuroscience with new tools from synthetic biology to develop yeastons - Saccharomyces cerevisiae cells that can collectively emulate a feedforward neural network through engineered cell-cell communication processes and programmable transcriptional logic. Crucially, yeaston networks will be designed to tolerate the inherent noisiness of single-cell biomolecular information processing and require no specific higher order spatial organization or patterning. The project members will build new protein receptors for small molecule signals and genetic logic systems that will enable single yeastons to emulate nodes in a feedforward neural network. The input-output behavior of single yeastons and yeaston networks will be quantitatively characterized, making it possible to evaluate the potential for scalable computation in yeaston systems. High-level models from neuroscience will be used to develop design principles for assembling robust yeaston networks and to derive scaling laws for yeaston computing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
使用简单的原材料廉价培育的大型三维细胞克隆可以制造成廉价、节能的计算机。使用活细胞进行计算的一个基本挑战是,通过细胞进行计算很容易出错,细胞在细胞培养中分裂、死亡和重组,使得维护定义的体系结构变得困难。这项研究将探索基于酵母细胞的计算系统的设计,灵感来自动物脑细胞执行计算的方式。要在电子、计算和生物的交叉点上发展新的知识,需要熟悉这些领域的新一代学生,他们能够在协作团队中工作。在与包括德克萨斯州奥斯汀大学新生研究倡议和JHU女性科学与工程研究在内的组织的合作基础上,PI将开发项目,允许本科生研究人员小组参与长期研究项目,在这些项目中,学生有机会作为大学间协作团队的一部分进行独立调查。该项目将把计算机体系结构和系统神经科学的想法与合成生物学的新工具结合起来,开发酵母-酿酒酵母细胞,通过工程细胞-细胞通信过程和可编程转录逻辑,共同模拟前馈神经网络。至关重要的是,Yaston网络将被设计成能够容忍单细胞生物分子信息处理的固有噪声,并且不需要特定的更高阶的空间组织或图案。项目成员将为小分子信号和遗传逻辑系统建立新的蛋白质受体,使单个酵母能够模拟前馈神经网络中的节点。单个Yaston和Yaston网络的输入-输出行为将被定量表征,从而有可能评估Yaston系统中可伸缩计算的潜力。神经科学的高级模型将被用来开发组装强大的Yaston网络的设计原则,并推导Yaston计算的比例定律。这一奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
