In the forests of Rwanda’s Volcanoes National Park, steep ridges and thick mist often hide mountain gorillas from human eyes. Scientists used to rely on camera traps and ranger patrols to track these endangered animals, but rugged terrain and security risks in the border area made this difficult. No
Scientists took a close look at a quiet stretch of coast where the Skagerrak Sea meets land. They wanted to see how certain chemicals move around in water, mud, and shellfish. These chemicals, called PAHs, come from old fires, car exhaust, or oil spills. But the team also checked for two new types o
Rivers hide more than just fish and rocks. They also carry invisible chemicals from everyday products. One group, called PFAS, sticks around for years and mixes into water systems. Scientists recently tested a common underwater plant, Potamogeton crispus, to see if it could act like a warning sign f
Hydrangea flowers are turned into tiny, glowing dots that shine blue under UV light. The dots contain nitrogen and emit bright light when exposed to 365‑nanometer radiation, but they fade quickly – within half an hour. This rapid loss of glow makes them useful as a “single‑use” security mark that ca
Plastic waste is everywhere. It's in our oceans, our rivers, and even on our beaches. The problem is growing fast. Many countries are trying to keep track of this mess. They focus on big pieces of litter, like bottles and bags. They also look at tiny bits, called microplastics. But there's a gap. Th
In the Amazon's coastal areas, where tides rise and fall and seasons change, tiny zebra snails are doing something amazing. They are helping scientists understand pollution levels in these waters. Researchers studied these snails at three different spots along the coast. Each spot had different amou
Copper is everywhere. It is in the water we drink and the soil we walk on. But too much of it can be harmful. This is why finding ways to measure copper levels accurately is so important. A new method has been created to do just that. It uses a clever trick of light and chemistry to spot copper in o
TBBPA is a nasty chemical found in many places. It is toxic and can harm living things. So, scientists are always looking for better ways to find it. They want methods that are simple, cheap, and reliable. One new method uses a special kind of sensor. This sensor is made from a mix of copper and org
The US has made a surprising move to stop sharing air quality data from its embassies and consulates around the world. This decision has left scientists and health experts concerned, as this data was crucial for tracking global air quality and protecting public health. The US State Department annou
Imagine a vast, beautiful area with five massive lakes. This is the Great Lakes Basin, a treasure trove of freshwater. But there's a hidden danger lurking in these waters. Chemicals of emerging concern, or CECs, are sneaking in and causing trouble for the plants and animals that call this place home
