Wide-ranging scientific applications have created growing interest in ultracold molecules. Heteronu- clear bialkali molecules, assembled from ultracold atoms, enabled the study of long-range dipolar interactions and quantum-state-controlled chemistry, and recently have been brought to quantum degeneracy. Assembling such molecules one-by-one in tweezers for quantum information applications is one exciting avenue of this work. Beyond bialkalis, there are a range of molecules with advantageous properties for applications in quantum simulation and quantum information. We will describe in this talk our recent results on optical trapping and Λ-enhanced laser cooling and imaging of CaF molecules, the laser cooling of SrOH molecules, and the prospects for laser cooling of larger polyatomic molecules, such as CaOCH3, YbOCH3, CaCCCa, SrOCF2CF2OCa, and CaO(CH2)nOR, where R is a radical termination ligand. We also will very briefly mention recent progress in the field of electron electric dipole moment searches using heavy diatomic molecules, in particular the recent ACME result, and future prospects, including the use of polyatomic molecules.
