Estimating lifetime microplastic exposure

Every day, people are exposed to microplastics from food, water, beverages and air. But it's unclear just how many of these particles accumulate in the human body, and whether they pose health risks. Now, researchers reporting ...

Researchers reveal cost of key climate solution

Perhaps the best hope for slowing climate change—capturing and storing carbon dioxide emissions underground—has remained elusive due in part to uncertainty about its economic feasibility.

Study finds evidence of 55 new chemicals in people

Scientists at UC San Francisco have detected 109 chemicals in a study of pregnant women, including 55 chemicals never before reported in people and 42 "mystery chemicals," whose sources and uses are unknown.

'Lost' ocean nanoplastic might be getting trapped on coasts

As plastic debris weathers in aquatic environments, it can shed tiny nanoplastics. Although scientists have a good understanding of how these particles form, they still don't have a good grasp of where all the fragments end ...

Ghosts of past pesticide use can haunt organic farms for decades

Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it's uncertain whether chemicals applied to land decades ago can continue to influence ...
