This just dropped! Little did I suspect the full significance of the peculiar little #Mesolithic #moose #antler #axe that I found in the Historical Museum at Lund University's collection, or that I would find two more, for that matter! Enjoy! www.mdpi.com/2571-9408/9/...

The news just reached me that Dr Rena Maguire has passed away, leaving me shocked and saddened. She was so enthusiastic about science, horses, and equitation, interests we shared. My thoughts are with her family and close friends. So terribly tragic.

My latest for @newscientist.com
Two scientists walk past numerous enormous shelves, each divided into sections containing a huge array of weird items. One says:
“We still don't know what any of this is, where it came from, or what it does, but you have to admit we've shelved it all beautifully.”

After a wonderful week of respite, going to a scientific conference, only having to consider myself, I am now back in reality, with work, my PhD project, and around-the-clock care of my child with type 1 #diabetes and #autistic #burnout.
