Health & Ecosystems

A gray and tan pipeline crosses horizontally along the bottom of the image with a bright orange plastic construction fence draped over it. A yellow sign reading “Warning: Petroleum Pipeline” sits in the center of the image. In the background are a tall wooden fence, the top of a two-story house, bare trees, and a clear blue sky.

Settlement of Rapa Nui May Have Been Doomed by a Dearth of Dust

Rachel Fritts, Science Writer by Rachel Fritts 16 December 202127 March 2023

Rapa Nui and Hawai‘i offer a tale of two island settlements: Hawai‘i was close enough to Asia for continental dust to help replenish soil nutrients depleted by agriculture. Rapa Nui wasn’t.

Remote Sensing Could Predict Well Water Quality After Floods

by Jackie Rocheleau 16 December 202116 December 2021

After a flood, most people rely on officials to test public water sources. Private well owners are on their own, with little data to guide testing and treatment. New research seeks to change that.

In the foreground are tall grasses and green leafy bushes that cover hidden mines. A red sign with a skull and crossbones reads “Danger! Mines!” in both English and Khmer. Three wooden houses on stilts sit in the background of the image, and a group of villagers is gathered around the base of the central house. More houses extend into the distance, and a mountain range is visible on the horizon.

Native Super Trees Could Provide Climate Solutions to Houston

by Graycen Wheeler 15 December 20211 June 2023

A Houston nonprofit identified 14 native “super tree” species that are particularly promising for mitigating climate change and public health concerns.

In the foreground sits a yellow-beige pond, with tree trunks scattered about its surface. Two dredges that appear to be made of wood float by the banks, smoke rising from between them. In the background, the green rain forest towers, the blue sky smudged with white smoke.
