Female Brains More Valuable Than Males, Decrees Mother Nature

A recent study demonstrated that how male and female bodies respond to nutrient deprivation extends to neurons. Previous studies had shown that males tissue tends to conserve proteins while female tissue tends to conserve fat. The study subjected neurons taken from male and female rats to nutrient deprivation for up to 72 hours. Male neurons began to demonstrate more dysfunction after the first 24 hours, as well as visual evidence that the cells were breaking down their own components for fuel. Meanwhile female-derived neurons featured less dysfunction and focused on creating fat stores.

I know it makes for a fun article title, but in no way shape or form does the experiment even suggest that...

That's more marketing-over-accuracy. I see that a lot. The article just implies that the strategies employed by female genetics is better able to handle prolonged nutrient deprivation than male genetics.

You could, possible, stretch that to Nature adopting strategies that increase the survivability of female brains over the survivability of male brains, which makes sense given that long-term species survival requires the one that needs to be around for the long term (at least long enough for the child to be self-sufficient) over the one who's reproductive function ends pretty early on.

Response to starvation is a whole organism response - it could be that the female brain last better than the male brain because it is submitted to more stresses because the female body handles starvation not as well as the male body... The fact that this was done on cultured tissue vs starved then euthanized/dissected animals makes the study weaker.

That being said, I would imagine that pregnancy and lactation, two states that put tremendous nutritional strain on the body, have something to do with this sex difference.

You may have something there on the lactation. Given that it was fat storage that was being described, this may be what they are observing as a cellular effect.
