The answers on the question Are bees disappearing and why?, while giving a nice editorial, are most likely obsoleted by current research.
There are two problems here:
- The answers predate most of the discussions on on answers quality and are thus not up to standards. The accepted answer links to Wikipedia and gives a vague explanation only.
- It is my understanding that current research by Jeff Pettis (and other groups) all but solved the problem. Independent verification is still outstanding, however. Even so, this seems to be the most likely explanation yet. Unfortunately, the question currently doesn’t echo that and is very misleading to readers.
I would suggest putting a “current research” or similar banner on the question to warn casual readers that this is a hot topic of research.
