New study shows how Chicago pollution varies by neighborhood

If you live along one of the major interstate highways running through Chicago or directly next to Lake Michigan, you are regularly exposed to more air pollution than the rest of the city, a new Northwestern University study ...

'Deep proteome' project provides atlas for human complexity

A major puzzle of biology is that while the human genome contains roughly 20,000 genes, many comparatively primitive organisms—including the universally-studied worm C. elegans—have almost the same number of genes.

Pinpoint simulations provide perspective on universe structure

The universe is peppered with galaxies, which, on large scales, exhibit a filamentary pattern, referred to as the cosmic web. This heterogeneous distribution of cosmic material is in some ways like blueberries in a muffin ...

Researchers develop Ir/IrOx electron transport layer for stable organic solar cells

In recent years, the device efficiency of organic solar cells (OSCs) has been significantly improved, but the unsatisfactory stability restricts future commercialization processing.

Non-invasive imaging of spatiotemporal ion distribution across cell membranes

The cell membrane has numerous channels for the transport of various substances, including ions, between the cell and its environment. Ion transport determines the ion exchange rate (or the transmembrane transport coefficient), ...

Sunlight-absorbing organic compounds are produced on the wet surfaces of atmospheric particles

Heterogenous oxidation reactions can occur upon mixing chemicals that are in two different physical states, such a liquid and a gas; for example, in the atmosphere the reaction of gaseous nitrate (NO3) free radicals reaching ...
