Scientists have found a new way to learn about the habits of city residents by looking at their sewage. The technique, called wastewater‑based epidemiology, usually tracks drug use but now also measures food and drink markers. A fresh laboratory test can spot more than 40 different substances in raw
Cleaning wastewater efficiently is tricky, especially when dealing with low levels of ammonia. Traditional methods struggle because harmful bacteria called nitrite-oxidizing bacteria (NOB) keep growing and messing up the process. This new approach flips the script by using a smarter loading strategy
A big problem in factories is that copper mixed with phosphate chemicals sticks together so tightly it resists usual cleaning methods. The new trick uses a soap‑like molecule called CTAB that forms tiny bubbles in water. Inside these bubbles the copper‑phosphate is pulled close to iron and a powerfu
Nothing we flush ever really disappears. Most of it ends up in a treatment plant where armies of bacteria quietly get to work, breaking down what we send down the pipes. In cities with advanced systems like the A2O process, wastewater passes through three stages—first without oxygen, then with limit
The mayor of Chapin, South Carolina, announced that the town will no longer grant wastewater permits for residential projects with more than nine houses. This decision is part of a plan to pause rapid growth until the local treatment plant can be enlarged. The town’s sewage facility is already clos
When people step into a garden, they often see only flowers and vegetables. Yet behind every sprout lies a story of discovery that stretches back to ancient times. Early humans experimented with plants, learning which could feed them or heal wounds. This trial‑and‑error period was not painless; man
A new virus that many people are unaware of is spreading fast along the West Coast. Scientists use wastewater samples to track how common it is in communities, and recent data show that the human metapneumovirus (HMPV) is present in cities such as San Francisco, Sacramento and Davis. The virus reach
Carbon quantum dots, or CQDs, are like tiny solar panels that can clean polluted water. They work because their surfaces can be tweaked, and they separate electric charges very well. Scientists have shown that these dots can break down nasty chemicals such as antibiotics, dyes, and phenols with high
Paragraph 1. A big group of local people came together to tidy up a huge national forest, showing how community effort can protect nature for the future. Paragraph 2. The event was organized with help from a local environmental club and the U. S. Forest Service, bringing together volunteers
Martha Stewart will travel to Italy for the 2026 Winter Olympics. She is going with her friend Snoop Dogg, who will be a reporter there too. While she is in Milan, she told a magazine that she hopes to meet someone special. Milan is described as “a very sexy city. ” She said, “I’m waitin
