The first birth cohort study of its kind has found more than 90 percent of a group of pregnant women in Central Indiana had detectable levels of glyphosate, the active ingredient in Roundup, the most heavily used herbicide worldwide.
Researchers have used a combination of light and genetic engineering to controlling the metabolism, or basic chemical process, of a living cell. Building on techniques that already have transformed the field of neuroscience, the researchers used light to control genetically-modified yeast and increase its output of commercially valuable chemicals.
Researchers have identified a receptor on plant stem cells that can issue different instructions about how to grow. Tweaking this pathway can lead to bigger fruits or more seeds in important food crops.
A return to firewood is bad for forests and the climate. So reports William Schlesinger, President Emeritus of the Cary Institute of Ecosystem Studies, in an Insights article published today in the journal Science.
Discovery of why two of the most economically important bee species are immune to one neonicotinoid insecticide but not to others promises to yield chemical treatments that protect crops from pests without harming these essential pollinators, honeybees and bumblebees. Bee pollinators are equipped with biochemical defence systems, in the form of specific enzymes, that define their sensitivity to insecticides by enabling them to metabolise the chemicals safely, report an international team of researchers.
Efforts to create pesticides that are not toxic to bees have been boosted by a scientific breakthrough.
To make protein, soybean plants need a lot of nitrogen.Beneficial bacteria in root nodules typically assist. A new study shows it's possible to increase the number of soybean root nodules--and the bacteria that live there--to further increase crop yields. This could remove the need to apply additional nitrogen fertilizers.
Scientists say they are closing in on a cool solution to a sticky problem. They've found that adding tiny cellulose fibers extracted from banana plant waste to ice cream could slow melting, increase shelf life and potentially replace fats used to make the tasty treat. The researchers will present their results today at the 255th National Meeting & Exposition of the American Chemical Society.
Last year, 81 million people worldwide experienced severe food insecurity. About 80 percent of them live in Africa. While much of that food insecurity relates to civil war and violence in places like South Sudan and Nigeria, a good portion also stems from a sequence of five severe droughts that began in Ethiopia in 2015 and spread across parts of the continent in the ensuing three years.
An experiment conducted with 1,200 villagers in five developing countries found that when people are given cash to conserve, they cut down fewer trees both while they are being paid and after payments cease.
