Early-life nutrition can profoundly affect development through the regulation of gene expression even when the DNA is not altered. In this blog, a research team out of University of Alabama at Birmingham summarize the evidence that an “epigenetics diet” can help protect against adverse effects of environmental pollution exposure whilst in utero and after birth.

At Genome Biology we are as fascinated with plants as the next botanist and over the last couple of months we’ve seen some excellent plant research publish in the journal. Here, Senior Editor Andrew Cosgrove highlights a few of his favorites.


Data in a snap: Size, age and condition of elephants can be pulled out of photographs

Elephant 2

Photographs taken of wild animals might be more useful data sources than we previously considered. A new study published in Frontiers in Zoology shows that information about age, tusk size and even the sexual state of elephants can be extracted from routinely collected survey photographs, even when focal distance isn’t known and lots of different cameras are used. Here to tell us more is corresponding author of the study, Dr. Hannah Mumby.

Sex differences in postoperative cognitive functioning in older patients


Elderly adults are known to be at higher risk of cognitive dysfunction following surgical procedures, and there are known sex differences in cognitive decline rates in Alzheimer’s disease, but no studies have really examined how sex as a biological variable may contribute to post-operative cognitive dysfunction. This blog, written by the authors of a recently published study in Biology of Sex Differences, explain their recent study which sought to address this question.
