Rocky Mountain not-so high: Oil, gas wells drive down Colorado home values, reveals WVU research
A cornucopia of contradiction is dotting the landscape of Colorado’s Front Range, at the foot of the Rocky Mountains. In the foreground of dramatic peaks and valleys, which are never out-of-season for a stunning snapshot, are — oil and gas…
Engineers help with water under the bridge and other tough environmental decisions
In two new papers, civil engineers explore how to make decisions using quantifiable social, economic and environmental guidelines. It’s called a sustainability-based optimized algorithm. It’s designed to help land managers, city planners, engineers and policymakers make decisions about civil engineering…
Harvard study shows where global renewable energy investments have greatest benefits
New metrics can guide investors and policymakers working to reach sustainable development goals
Microplastics found in oysters, clams on Oregon coast, PSU study finds
Tiny threads of plastics are showing up in Pacific oysters and razor clams along the Oregon coast — and the yoga pants, fleece jackets, and sweat-wicking clothing that Pacific Northwesterners love to wear are a source of that pollution, according…

Prey-size plastics are invading larval fish nurseries
A new research study has revealed that larval fish species from various ocean habitats are now being threatened by plastic pollution that infects their nursery habitats—at levels on average, eight times higher than those recently found in the Great Pacific…
Gold mining critically impairs water quality in rivers across Peruvian biodiversity hotspot
Study examines increased sediment levels in rivers as a result of mining
Hot town, springtime in the city: Urbanization delays spring plant growth in warm regions
GAINESVILLE, Fla. — The first appearance of bright green leaves heralds the start of spring, nudging insects, birds and other animals into a whirlwind of action. But a new study shows that urbanization shifts this seasonal cue in nuanced ways,…
Researchers find nature’s backup plan for converting nitrogen into plant nutrients
Although nitrogen is essential for all living organisms — it makes up 3% of the human body — and comprises 78% of Earth’s atmosphere, it’s almost ironically difficult for plants and natural systems to access it. Atmospheric nitrogen is not…
