Pervasive plastic contamination and flawed analytical techniques have clouded the science on microplastics in the human body. In an interview, Australian scientist Cassandra Rauert, who built a plastic-free lab to study human exposure, explores the challenges for researchers.

As residential batteries have become more energy dense, cheaper, and smaller, more households are storing their excess solar power. Now, utilities and energy companies in dozens of countries are buying up those electrons, bundling them together, and using them to balance the grid.

Despite years of opposition, a 900-mile crude oil pipeline through East Africa is about to be completed, and its environmental and social risks are coming into focus. Campaigners in Uganda and abroad are making a final push to halt the project before the oil starts to flow.
Rising temperatures are set to drive up emissions from wildfires, fermenting wetlands, and melting permafrost, but these “feedback loops” are poorly captured in climate models. Scientists are racing to make sense of these emissions to gauge how much warming may lie ahead.

In January 2025, the Trump administration began shutting down projects within the EPA’s independent science division that touched on climate change and environmental justice. Air quality researcher Thomas Luben, who had worked at the agency for 18 years, was fired for objecting.

At one time, kelp forests — which shelter fish, slow erosion, and sequester carbon — grew along a third of the world’s coastlines. Now, scientists are working to bolster heat-stressed kelp by attacking the urchins that prey on them and transplanting hardier kelp varieties.
A growing body of research shows how air pollution, fertilizers, and fungicides are altering the chemical signals that plants and animals use to communicate. Scientists warn that insect reproduction, foraging, navigation, and even the pollination of crops could be affected.
In the icy waters of the Southern Ocean, whales and other marine mammals rely on krill to survive. But as the market for human dietary supplements and animal feeds booms, and climate change reduces krill populations, scientists worry there may not be enough to go around.
At a time when other public officials and the media are talking less about climate change, Sheldon Whitehouse remains fiercely outspoken. He delivered his 307th climate speech on the Senate floor this month and is pushing back against the recent trend of “climate hushing. ”
While China's push to modernize sparked a surge in burning coal, India is turning to increasingly cheap solar to meet its booming energy needs. Though it faces big hurdles, including a rickety grid, India's solar buildout could soon be a model for other emerging economies.
When Yale E360 launched in 2008, it was a pioneer in online environmental journalism, filling a critical gap in coverage. As he prepares to step down, founding editor Roger Cohn reflects on his years at e360, his debt to the writers he’s worked with, and his hopes for the future.
The campaign to restore the Everglades has received a boost with completion of a key project that returns the flow of water to 55,000 acres that had once been drained for development. Experts see it as a major step forward in bringing back South Florida’s River of Grass.
Scientists are increasingly worried that a vast system of ocean circulation, which delivers warmth to northern Europe and impacts climate globally, is at risk of collapse. Mounting evidence suggests it may be nearing a tipping point, though the research is far from certain.
