Exposure to ultrafine particles from traffic alters the expression of many genes in human olfactory mucosa cells, a new study shows. The study is the first to combine an analysis of emissions from ...

While smell plays a considerable role in the social interactions of humans -- for instance, signaling fear or generating closeness -- for ants, it is vitally important. Researchers have found that a ...

While smell plays a considerable role in the social interactions of humans - for instance, signaling fear or generating closeness - for ants, it is vitally important. Researchers from New York ...

The signaling mechanisms underlying the transition from stem cells to olfactory neurons has been described. Cellular differentiation of stem cells into specialized cells requires many steps, including ...

A research team led by scientists at Columbia’s Zuckerman Institute used techniques including single cell genomics, to describe a previously undetected RNA-mediated mechanism in mice that could ...

Cellular differentiation of stem cells into specialized cells requires many steps, including division, to create more cells; fate determination, which is a commitment to a specific lineage or ...

Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. Led by the University of Eastern Finland, ...

For the first time, researchers have used cells from one species to restore the sense of smell in another. In an article published April 25 in Cell, researchers from Columbia University described how ...
