Researcher and physician Amy Baxter unravels the symphony of connections that send pain from your body to your brain, explaining practical neuroscience hacks to quickly block those signals.

Researchers led by Dr. Barbara Huber have recreated the ancient scent used in the mummification of an Egyptian noblewoman over 3,500 years ago. Dubbed “the scent of eternity,” it will be presented at Denmark's Moesgaard Museum.

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.
