A veterinary ophthalmologist wanted to determine factors, including age and vision, that influence a dog's interest in interacting with video content. Ultimately, the goal of the study, which launched two years ago, was to support development of more sensitive ways to assess canine vision -- something that has been sorely...
Stalagmites as Climate Archive
When combined with data from tree-ring records, stalagmites can open up a unique archive to study natural climate fluctuations across hundreds of years, a research team including geoscientists from Heidelberg University and the Karlsruhe Institute of Technology have demonstrated.
A New, Rigorous Assessment of OpenET Accuracy for Supporting Satellite-Based Water Management
A new study offers a comprehensive multi-model, large-scale accuracy assessment of an operational satellite-based data system to compute evapotranspiration.
The First Assessment of Toxic Heavy Metal Pollution in the Southern Hemisphere Over the Last 2,000 Years
An international team of scientists led by DRI found evidence of Southern Hemisphere heavy metal pollution preserved in Antarctic ice cores from early Andean cultures and Spanish Colonial mining that predates the Industrial Revolution by centuries.
Cobalt-free batteries could power cars of the future
A new battery material could offer a more sustainable way to power electric cars. The lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel.
Efficiently moving urea out of polluted water is coming to reality
Researchers have developed a material to remove urea from water and potentially convert it into hydrogen gas. By building these materials of nickel and cobalt atoms with carefully tailored electronic structures, the group has unlocked the potential to enable these transition metal oxides and hydroxides to selectively oxidize urea in...
Ancient ‘chewing gum’ reveals stone age diet
What did people eat on the west coast of Scandinavia 10,000 years ago? A new study of the DNA in a chewing gum shows that deer, trout and hazelnuts were on the diet. It also shows that one of the individuals had severe problems with her teeth.
HIV antibodies protect animals in proof-of-concept study
Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The antibodies -- a human broadly neutralizing antibody and two antibodies isolated from previously vaccinated monkeys -- target the fusion peptide, a...
The heat is on: Scientists discover southern Africa’s temps will rise past the rhinos’ tolerance
Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts aimed at protecting rhinos have focused on poaching, but until now, there has been no...
Climate Change May Make Wildfires Larger, More Common in Southern Appalachian Region
In a new study, North Carolina State University researchers found that more extreme and frequent droughts would dramatically increase the amount of forest burned by wildfire in the southern Appalachian region of the Southeast through the end of the century.
