In this colloquium style talk, I will first give a quick introduction to etale cohomology and Tate conjecture. Then I will explain my joint work with Yichao Tian and Xinwen Zhu on constructing cycles on the special fibers of Shimura varieties. The talk should be accessible to students who are reasonably familiar with the language of algebraic geometry.
