The anomalous microwave emission (AME) is a dust-correlated signal that shows up in the microwave range. Strong interest in this emission has arisen since its discovery in the late 90s, due to its role as a CMB contaminant, and also because it provides a new way to explore the ISM physics. As a consequence, there has been a strong combined effort over the last decade in this regard, with several targeted observations in individual clouds, as well as different models that have been proposed to explain the origin of this emission, the most promising of which is the so-called ``spinning-dust'' emission. In this talk I present new observations of this phenomenon in the Pleiades reflection nebula using microwave data from the WMAP satellite and from the Cosmosomas experiment te{genova_11}. I will also discuss the implications that the AME wave background (GWB).
