I've got a PSA to the T cell receptor researchers of #immunosky to let you know about a new paper we've just got out: doi.org/10.1016/j.im...
This covers how our field is handling the sets of germline #TCR genes used in our research. Maybe not the most glamorous topic, but it’s kind of a big deal…

Update from MRC re funding
They've separately said:
Our transition to new ways of working also means we unfortunately expect to make a reduced number of awards to applications currently being assessed by our four research boards and developmental pathway funding scheme.

This isn't *why* we should encourage scientists to have interests outside of the lab (they are their own reward), but it's an excellent demonstration of the inspiration that can happen when you do

Computational X-scan didn't work super well for improving the specificity of the design process. There's potential for deorphanization but the design problem is actually simpler than deorphanization since you're free to sample a huge space.
