Simulate extensive range of selective [dis]appearance & ageing scenarios, life histories; explore published datasets; or analyze + diagnose your own data with sophisticated & comprehensive features, approaches, & models, which explain the mechanism & biology! Check out our shiny app, disappR!

Genetic Variation in Drosophila melanogaster Aggression
Animals fight for resources to obtain fitness benefits; most contests are intrasexual, and males tend to fight more than females. Although the genetic basis of male aggression is well studied, we know...

Now out in @royalsocietypublishing.org "The seminal proteome of a monandrous fly, Drosophila subobscura". We discovered that, despite monandry, D subobscura's seminal fluid is surprisingly similar D melanogaster's, and likely shaped by conflict! royalsocietypublishing.org/rspb/article...

Finally watched One Battle After Another. I really enjoyed it, but I’m not sure it’s a “best movie of the year” type film. Between the two, I would have picked Sinners.

Adult content advisory. No laughing at the back please. A major multi-species study by Oxford University researchers has found that sperm deteriorates rapidly in storage (in males or females), and so regular ejaculation before taking semen samples or assisted reproduction is recommended.

Sperm can “age” independently of the male, when stored in male or female reproductive tracts. Our meta-analysis finds widespread evidence across animals (including abstinence in men). Important consequences for fertility, sexual selection, haploid selection! doi.org/10.1098/rspb...
