From sizzling bacon in the kitchen to wildfire smoke in the sky, cooking and pollution release microscopic particles that affect humans' health, the air they breathe, and even weather and climate.

Rochester biologist Anne S. Meyer and her colleagues created “bio-stickers” that speed up plastic breakdown in marine environments.

Municipalities and federal agencies monitor U.S. waters for microcystins, a toxin produced by harmful algal blooms in Lake Erie, but a University of Michigan study shows that the blooms produce a greater range of potentially toxic compounds than previously known.

Levels are “three times higher than what we’re allowed to shower in, or drink,” UMass Amherst researcher says.

Reducing methane emissions will slow climate change but could also slow the recovery of the stratospheric ozone layer, new research from the University of Reading shows.

Urban planning needs to tackle greenhouse gas emissions – and an important way to achieve this is by reducing the number and length of car commutes. 

A new, interactive global map has been launched to help people understand how pollution and climate change are affecting lakes around the world.
