Advanced Biomass Cookstoves Provide Benefits in Field Settings, But Less than Expected from Lab Testing

Researchers from North Carolina State University and the Liverpool School of Tropical Medicine have found that while advanced wood-burning cookstoves can provide benefits to the environment and climate, these benefits are less than expected due to higher emissions measured in the field compared to laboratory settings. The study, conducted in rural Malawi, found that pollutant emissions from these stoves were much higher than was reported in laboratory testing, due in part to how the stoves were being used.

Research in the news: A 520 million-year-old food plan

Anyone who’s read a children’s menu at a restaurant knows that kids and adults tend to like different foods. New research suggests at least one animal species had the same arrangement half a billion years ago.

It seems the earliest ancestors of spiders and horseshoe crabs, called chelicerates, had separate ecological niches for adults and larvae. They ate different foods, in other words, and did not compete for the same prey. This approach has been seen in many modern animal species, but never in one this old. (more…)
