People of color hardest hit by air pollution from nearly all sources Apr 28, 2021 1:00 pm948 views Various studies show that people of color are disproportionately exposed to air pollution in the United States. However, it was unclear whether this unequal exposure is due mainly to a few types of emission sources or whether the causes are more systemic. A new study that models peoples’ exposure to air pollution – resolved by race-ethnicity and income level – shows that exposure disparities among people of color and white people are driven by nearly all, rather than only a few, emission source types.

Channel migration plays leading role in river network evolution, study finds Apr 14, 2021 10:00 am681 views Satellite views of Earth’s major river systems reveal their familiar treelike drainage patterns. The pattern – called dendritic – and its prevalence suggests that it may be the optimal state in which rivers exist. Challenged by the knowledge that numerical models of drainage evolution have yet to substantiate this assumption, researchers are now thinking of rivers as existing in a persistent reorganizational state instead of being in a set, stable configuration. Understanding this has implications for land use and infrastructure management decisions. New 3D microbatteries stand up to industry standard thin-film counterparts Apr 5, 2021 8:00 am1181 views The thin-film lithium-ion batteries used in microdevices such as portable and medical electronics may supply a good amount of power relative to their mass, but do not provide enough power for many devices due to their limited size.
