How did digits evolve? While it is clear that they derive from genetic programs already present in fish, their precise origin ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

A thin section of a maize ear at a very early stage of development (about 3 millimeters long). Each color represents the ...

Most people recognize Alzheimer's from its devastating symptoms such as memory loss, while new drugs target pathological aspects of disease manifestations, such as plaques of amyloid proteins. Now a ...

A new study suggests that a group of cells, key for the health of blood and the immune system, are vulnerable to aging-like ...

How rapidly gene expression in a single cell changes over time can provide insight into how cells might become more ...

Sex-biased gene expression in the body organs evolves rapidly, supporting a mosaic model of maleness and femaleness across tissues and thus challenging binary views of sex characteristics in mammals.

Biopharma researchers and translational scientists are facing a challenge –understanding the tumor microenvironment (TME).

In a study in mice, researchers have identified genes associated with the dramatic transformation of the mammary gland in ...
