Google DeepMind Co-Scientist 加速逆转细胞衰老研究,数据分析从六个月缩至几天
Fast-tracking genetic leads to reverse cellular aging
- 1Co-Scientist 扫描数万篇论文后提出 20 多个候选基因因子,实验室验证了其中几个能驱动细胞年轻化
- 2官方称筛选数据结合文献的分析原需研究者最多六个月,借助 Co-Scientist 缩短到几天
- 3两名生物学家的实验室用它寻找让皮肤、毛发、肌肉等组织细胞远离衰老状态的基因通路
- 4衰老研究此前卡在两个环节,选哪些基因通路做实验,以及如何解读实验产生的海量数据
AI 在生命科学里从检索文献扩展到提出假设并获得实验验证,科研中最耗人的数据解读环节被显著压缩。
- 影响:假设筛选与数据解读环节的耗时在本案例中从月级压到天级,同类研发团队可参照重排工期与人手;目前成果出自厂商与单一实验室的合作叙述,其他领域复制效果尚无公开参照;积累大量文献与实验数据的团队是这类工具的直接适用方。
- 参考:研发负责人可考虑盘点综述写作与实验数据解读占用人时最长的环节,估算压到天级后的排期收益;值得选一个假设生成或数据解读任务小范围试点,并保留实验验证环节核验产出;引入前先明确实验数据与文献库的使用边界。
- 依据:20 多个候选因子、数万篇论文扫描与六个月到几天的提速均出自 Google DeepMind 官方博客,官方口径,暂无独立验证;实验结果为博客转述的合作实验室测试。
Two of the biggest bottlenecks in aging research are deciding which genetic pathways to test and making sense of the vast data those experiments produce. Biologists Omar Abudayyeh and Jonathan Gootenberg are using Co-Scientist to help them blast through both.
Their lab runs huge genetic screens that flip thousands of genes on or off then reads how cells respond to these changes. The goal is to find changes that push cells away from senescence – a damaged state linked to aging – and toward a youthful state in tissues such as skin, hair, and muscle.
Co-Scientist is helping on two fronts. First, it generates leads. When the team asked it to trawl the scientific literature for factors that might reverse aging, it scanned tens of thousands of papers, considered a multitude of hypotheses, and ultimately proposed more than 20 novel, plausible genetic factors to test. Lab tests validated a couple Co-Scientist’s hypotheses, with its recommended factors successfully driving cells into a younger state with improved overall function.
Second, Co-Scientist speeds up the follow-through. Once the team has results from a big screen, they have to figure out what the enormous amount of data might mean, and which directions are worth pursuing next. That kind of analysis – trying to connect test results to years of scattered scientific literature – can take a researcher up to six months. Having Co-Scientist analyse their screening data alongside the literature, that work is slashed to just a few days.
