Mother's Milk, Literature Sleuths, and Science Fairies

I am currently polishing a manuscript for submission (hence the obvious necessity of working on a blog post, next I will clean my bathroom tile). Delving deep into the literature to precisely contextualize my results, I despair that I will never be able to read ALL the things. For example, entering two key search terms- ‘lactation’ and ‘glucocorticoids’- returns 24,800  results in Google Scholar . John Medbury (LAZY J Studios) Reading all that is just not going to happen. Merely identifying the most pertinent papers can be challenging. And with every new literature search, I discover articles that I clearly should have read ages ago. Um especially when I was writing this .  I had that sinking feeling yesterday as I read a killer review.  In the text the authors described an exciting dynamic; high food intake, high cortisol concentrations in mother’s milk, and high activity in kittens covary while low food intake, low cortisol concentrations in mother’s milk, and low activity in kitten

Hormones in Mother’s Milk Influence Baby’s Behavior

In March, Nicholas Day at SLATE wrote a column about the science of breastmilk , showcasing the emerging perspective that “Milk is food; Milk is Medicine; and Milk is Signal.” People seemed particularly intrigued by the hormonal ‘Milk is Signal’ aspect of mother’s milk, although it’s the least understood. Sidebar: Why don't more kid costumes come in adult sizes.  Seriously. Recently, Skip Bartol and colleagues coined the term “lactocrine programming” to describe the process by which hormones present in mother’s milk permanently shape physiological processes within in the young (Bartol et al. 2009). A growing body of evidence has demonstrated that hormones from the mother, ingested through milk, bind to receptors within the young. Once these “maternal-origin” hormones bind, they seemingly trigger hormonal signaling cascades as would the young’s own hormones. Previously I described that hormones present in milk-specifically adiponectin - are associated with infant growth althou
