Many birds and other wildlife die following an oil spill, but there are also other potential long-terms effects of oil exposure on animals.
The human genome encodes instructions for which genes are expressed in what cell type, along with other molecules that control how much and when these genes are expressed. Variation in the regulation of gene expression gives rise to the diverse tissue types, with diverse functions, in the human body. Finding new clues about the molecular origins of disease is the goal for a comprehensive atlas of variation in gene expression.
A high-fat diet changes fungi in the gut and may play a role in the development of obesity, according to a new study. While gut microbes have previously been implicated in the development of obesity, this study shows that fungi may also play a role.
