2004 年 11 月 20 日 Google 推出了学术搜索（Google Scholar），提供了一个可以免费搜索学术文章的网络搜索引擎。过去 20 年，Google Scholar 逐渐成为科学界最重要的工具之一。但近年随着 AI 工具的兴起，科学家开始越来越多的使用这些新工具。华盛顿大学的 Jevin West 认为，如果 Google Scholar 有一天不再是科学行业的主要搜索工具，那么这一天可能就是现在。以 ChatGPT 为代表的 AI 大模型被科学家日益用于搜索、评估和总结科学文献。新加坡管理大学的学术文献管理员 Aaron Tay 以前的默认搜索工具是 Google Scholar，但现在开始使用 AI 工具。Google Scholar 联合创始人 Anurag Acharya 欢迎这一变化，他表示 Google Scholar 尚未提供 AI 生成的搜索结果摘要，原因是 Google 尚未找到有效的解决方案，以简洁的方式总结多篇论文的结论并保留重要背景信息。

Subsequently, control of the company was reportedly handed to oligarchs Alisher Usmanov and Igor Sechin, both allegedly close associates of Russian leader Vladimir Putin. What distinguishes the app from competitors is its use of what's known as channels: Public or private feeds of photos and videos that can be set up by one person or an organization. The channels have become popular with on-the-ground journalists, aid workers and Ukrainian President Volodymyr Zelenskyy, who broadcasts on a Telegram channel. The channels can be followed by an unlimited number of people. Unlike Facebook, Twitter and other popular social networks, there is no advertising on Telegram and the flow of information is not driven by an algorithm. The last couple days have exemplified that uncertainty. On Thursday, news emerged that talks in Turkey between the Russia and Ukraine yielded no positive result.
