Imagine using insects as a source of chemicals to make plastics that can biodegrade later — with the help of that very same type of bug. That concept is closer to reality than you might expect.

What does it mean to have cooked something? Most people are probably thinking cooking involves a heat source to break down proteins. But what about ceviche? No heat is used to “cook” it but it still undergoes a process where proteins are denatured.

Scientists report that aloe peels, often discarded as agricultural waste, can ward off bugs, acting as a natural insecticide. They have identified several bioactive compounds in extracts from the peels that deter insects from feasting on crops.

In this video, we take a show TKN analysis, a critical method for determining total Kjeldahl nitrogen (TKN) in soil and wastewater samples.

TKN is a key indicator of the nitrogen content in environmental samples, providing critical information for monitoring and assessing environmental impacts. We demonstrate each step of the Kjeldahl method for TKN determination, which involves digestion, distillation and titration, and how it can be applied to both soil and wastewater samples.

Are alternative meats actually better for us and the planet? Carolyn Beans investigates the differences between farmed meat, plant-based meat and lab-grown meat.

Forever chemicals are extremely useful in industry, but they can also leak into the environment, your drinking water and your blood. And they last (practically) forever. But now chemists have a new way to destroy them: burning them with water.

Your weekly science news roundup is here.

Researchers have developed modified iron oxide particles, known as "smart rust", that can grab onto pollutants in water and help with their cleanup. The new method is cheaper and more simple than other alternatives, they say.

Researchers developed a new approach for simulating seafood, using plant-based proteins and a 3D printer, and used it to make a snack inspired by fried calamari rings from squid.

Researchers explored the effects of adding oil to tempera paint to improve understanding of how various paint formulas would affect the appearance of finished works.
