I think I had a good science idea this weekend. I’m hoping if I ignore it, it’ll go away and I can try relaxing.

Christmas, innit. How about we get some things for women and children with nothing who are escaping domestic violence? You can do that, as ever, via the brilliant Refuge. Check this out: donate.refuge.org.uk/page/180196/...
Buy a parcel and help give mums and their children in our refuges their first Christmas of freedom.
When a child arrives at a refuge in the countdown to Christmas, they’re withdrawn and in shock.

Had the absolute pleasure of mounting and sampling some greater argentine (Argentina silus) otoliths today - look how beautiful they are! And so easy to age!
These specimens were dissected at sea around 1AM, after a full-day migraine - gratifying to have them be nice samples!
