Fossil carbon dioxide emissions increased by 40 percent from 1990 to 2008, according to new findings. Coal has bypassed oil as the largest source of CO2 emissions.
Scientists have found a clever way to use traditional GPS satellite signals to measure snow depth as well as soil and vegetation moisture, a technique expected to benefit meteorologists, water resource managers, climate modelers and farmers.
A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. Now, researchers have reconstructed one of the earliest evolutionary steps yet: generating long chains of RNA from individual subunits using nothing ..
Surplus biomass from the production of flax sheaves, and generated from Brassica carinata, a yellow-flowered plant related to those which engulf fields in spring, can be used to produce bioethanol.
With the introduction of a single bacterial gene into yeast, researchers have achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the major by-product glycerol'
