We still don't know what dark matter is but a class of leading candidates

are weakly interacting massive particles or WIMPs. These WIMP models are

falsifiable, which is why we like them. However, the epoch of their

falsifiability is upon us and a slew of data from different directions is

placing models for WIMPs under pressure. I will try and present an updated

overview of the different pieces of evidence, false (?) alarms and

controversies that are making this such an active area of research at the

moment.
