Recent mercury pollution on the rise, but quick to change, Dartmouth-led study shows

A Dartmouth-led study using a 600-year-old ice core shows that global mercury pollution increased dramatically during the 20th century, but declined faster than previously thought after emissions started to decrease in the late 1970s. The study suggests present-day efforts to cut mercury emissions will reduce pollution more quickly tha...

Iron: A biological element?

A recent study published in PNAS reveals that half of the iron in banded iron formations originated from ancient bacteria metabolizing iron two and a half billion years ago. The findings provide new insights into the evolution of our planet and the origins of life, with significant implications for fields like mining and astrobiology.

Mining pollution alters fish genetics in southwest England

New research reveals that mining pollution has led to a significant reduction in the genetic diversity of brown trout populations in southwest England. The study found that these fish have adapted to live in water with high levels of metal contaminants, but this adaptation comes at the cost of reduced genetic variation.

Study: World's primary forests on the brink

A new study reveals that only five percent of the world's pre-agricultural primary forest cover is found in protected areas, with most forests under threat from industrial logging, mining, and agriculture. Experts call for international policies to reduce pressure on primary forests, preserving their biodiversity and ecosystem services.

UCSB researcher documents the enduring contaminant legacy of the California gold rush

A new study by UCSB researcher Michael Singer shows that sediment-absorbed mercury is being transported from the Sierra Nevada mountains to the Central Valley lowlands through major floods. This process poses a huge risk to the region's ecosystems and human population, as mercury-laden sediment is carried into ecologically sensitive re...
