开源地球系统基础模型更新添加概率集合预报，在88.9%目标上优于ECMWF ENS，有益于能源、农业和气候风险应用。 (score: 0.90)
Aurora 1.5, a major update to Microsoft's open Earth-system foundation model, adds 22 weather variables, hourly resolution, and probabilistic ensemble forecasting. Released on GitHub and Hugging Face, it outperforms ECMWF ENS on 88.9% of evaluated targets and supports energy, agriculture, and climate risk applications. The model connects open research with operational use via Microsoft Weather services.
- Adds 22 new weather variables, hourly temporal resolution, and ensemble forecasting capability.
- Released as open source on GitHub and Hugging Face for global community use and adaptation.
- Outperforms ECMWF ensemble on 88.9% of evaluated variable-lead-time targets.
- Reduces tropical cyclone track error by roughly one-third compared to original Aurora.
- Supports applications in energy, agriculture, transport, and climate risk management.
- Integrated with Microsoft Weather services for enterprise-grade operational use.
- Collaborations with UK Met Office and Terradot for climate and carbon removal applications.

GitHub通过自定义属性和自动化解决了1.1万个仓库的所有权覆盖问题，45天内改进了安全工作流并减少了攻击面。 (score: 0.85)
GitHub faced a problem where over 11,000 non-archived internal repositories had no clear owner, causing issues for security workflows like secret scanning remediation. They designed a new ownership model using GitHub custom properties with types: Service Catalog, Hubber Handle, and Team. They automated sync from Service Catalog, enforced ownership at creation, and ran a 30-day grace period followed by archival of unowned repos. The effort achieved 100% ownership coverage for active repositories within 45 days, reducing surface area and improving remediation routing.
- GitHub had over 11,000 non-archived repositories with no clear owner.
- They designed an ownership model with custom properties: ownership-type and ownership-name.
- Ownership types: Service Catalog, Hubber Handle, and Team.
- Automated sync from Service Catalog covered about 1,500 repositories.
- Enforced ownership at repository creation time.
- 30-day grace period then archival of unowned repositories.
- Achieved 100% ownership coverage for active repos in 45 days.
