Researchers think they have a better understanding for how ancient North Americans thrived for centuries in northwestern New Mexico’s arid desert. A multidisciplinary team of experts from the University of Cincinnati determined that the sandy soils of Chaco Canyon were not too salty to grow crops such as maize, beans and squash for the more […]

An interdisciplinary team of researchers funded by the National Science Foundation (NSF) has concluded that bacteria in a lake 800 meters (2,600 feet) beneath the West Antarctic Ice Sheet may digest methane, a powerful greenhouse gas, preventing its release into the atmosphere. As part of the NSF-funded Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) […]

  Rice University materials scientists have created a light foam from two-dimensional sheets of hexagonal-boron nitride (h-BN) that absorbs carbon dioxide. They discovered freeze-drying h-BN turned it into a macro-scale foam that disintegrates in liquids. But adding a bit of polyvinyl alcohol (PVA) into the mix transformed it into a far more robust and useful […]

Sea otters have low genetic diversity like endangered species, biologists report
Sea otters have low genetic diversity, which could endanger their health as a species, a UCLA-led team of life scientists has discovered. The findings have implications for the conservation of rare and endangered species, in which low genetic diversity could increase the odds of extinction. Genetic diversity is a measure of how many differences exist […]

Lake Garda has not yet revealed all of its secrets. This attractive tourist destination, unique for its physical and environmental characteristics, is also a case study for several international research teams. One of these, made up of scientists from the universities of Trento and Utrecht, has just made a new and unexpected discovery: the planetary […]

Natural gas and biogas have become increasingly popular sources of energy throughout the world in recent years, thanks to their cleaner and more efficient combustion process when compared to coal and oil. However, the presence of contaminants such as carbon dioxide within the gas means it must first be purified before it can be burnt […]
