A new system has been set up to tell the difference between pollution that comes from a city and pollution that comes from farms or factories. The idea is to help people fix the river faster by knowing exactly where bad water is coming from. The project was tested on the Sile River in Treviso,
In cities, the air isn’t just made of oxygen and dust. It carries invisible bits of plastic—some so small they can travel deep into our lungs. These tiny plastic pieces, called inhalable microplastics, don’t just float around randomly. New research shows their numbers change throughout the day and d
Since Russia invaded Ukraine, the Black Sea’s northwest coast has faced pollution it wasn’t ready for. Before the war, this area already dealt with natural shifts and years of human impact from farming and industry. Now, the fighting has added sudden bursts of harmful substances while making it hard
Algae act like the grass of underwater worlds, turning sunlight into food for fish and other creatures. But tiny amounts of metals in water can harm them. A new study looked at how different algae types react to these metals. Researchers found that diatoms—algae with silica shells—are easily damage
The Penobscot River runs through the heart of a nation that has watched it flow for millennia. Its banks have taught people how to fish, gather, and live in harmony with the land. In spring, the river awakens as ice melts and water rushes faster. The people call this time “People of the Dawn”
Back in 2009, scientists warned that car and truck fumes were filling the air with dangerous gases. These gases trap heat, make smog worse, and harm people's lungs. The government agreed and set rules to cut down on these emissions. But recently, the EPA decided to ignore those warnings by scrapping
Scientists are turning waste from burning plant material into a useful soil additive called biochar. When plants are heated in the absence of oxygen, they leave behind a charcoal‑like substance rich in carbon. This biochar can trap harmful chemicals known as polycyclic aromatic hydrocarbons, o
The Mekong River, a lifeline for 70 million people across Southeast Asia, is facing a new danger that could endanger the region’s food supply. Rare‑earth mining, driven by global demand for electronics and military equipment, is creating toxic runoff that flows into the river’s tributaries. Th
A new study shows that lightweight expanded clay aggregates, a common building material, are flooding Portugal’s beaches. Researchers walked along 50‑meter stretches of shore at eight different spots around Aveiro, from open ocean dunes to sheltered lagoon edges and a busy port channel. At eve
California's Salton Sea used to be a vacation hotspot in the mid-1900s with its sandy beaches and celebrity visitors. But decades of water mismanagement have turned this 340-square-mile lake into a drying disaster zone. As water disappears, it leaves behind a toxic mix of old pesticides, heavy metal
