The conversion of natural forests and grasslands to agriculture and livestock is the biggest cause of global biodiversity loss.
Planting and Management of Improved Grass in Tropical Savannas Can Increase Soil Carbon by 15 Percent, New Paper Finds
Scientists in Colombia show that well managed pasture can store more soil carbon while reducing nitrous oxide (N2O) emissions to offset the climate impact of livestock.
New technology creates carbon neutral chemicals out of thin air
It is possible to capture carbon dioxide (CO2) from the surrounding atmosphere and repurpose it into useful chemicals usually made from fossil fuels, according to a new study.
A River Runs Beneath It: New Study Discovers a 460-Km River Under the Antarctica Ice Sheet
The discovery of a 460 km river under the Antarctica ice sheet could be the missing link to climate models.
High Power, High Potential
U of A laser experts join global network increasing access to technology that could revolutionize everything from space physics and nano-scale manufacturing to clean energy and cancer treatment.
The world will probably warm beyond the 1. 5-degree limit, but peak warming can be curbed
The world's current climate pledges are insufficient to keep global warming below 1.5 degrees Celsius. We will overshoot. In new research, scientists chart several potential courses in which the overshoot period is shortened, in some cases by decades.
Research reveals how a common bacterium may spread from the intestine
A typical gut bacterium that can spread through the body and cause a serious infection resists natural immune defenses and antibiotics by enhancing its protective outer layer, known as the cell envelope, according to a new study. The finding suggests possible new ways to target these bacterial infections.
Study Uncovers Widespread and Ongoing Clearcutting of Swedish Old Forests
Almost one fourth of Sweden’s last unprotected old-growth forest was logged between 2003 and 2019.
The gut microbiome’s supersized role in shaping molecules in our blood
Scientists have shown which blood metabolites are associated with the gut microbiome, genetics, or the interplay between both. Their findings have promising implications for guiding targeted therapies designed to alter the composition of the blood metabolome to improve human health.
Earth-sun distance dramatically alters seasons in the equatorial Pacific in a 22,000-year cycle
Earth is closer to the sun at some times of year than at others, with the time of closest approach shifting over a period of 22,000 years. This affects Earth's climate, including ice ages, but a team of scientists found that it also affects a yearly weather pattern, the Pacific...
