Scientists identify flank instability at a volcano with history of collapse — ScienceDaily

Landslides caused by the collapse of unstable volcanoes are one of the major dangers of volcanic eruptions. A method to detect long-term movements of these mountains using satellite images could help identify previously overlooked instability at some volcanoes, according to Penn State scientists. “Whenever there is a large volcanic eruption, there is a chance that […]

Scientists identify contents of ancient Maya drug containers — ScienceDaily

Scientists have identified the presence of a non-tobacco plant in ancient Maya drug containers for the first time. The Washington State University researchers detected Mexican marigold (Tagetes lucida) in residues taken from 14 miniature Maya ceramic vessels. Originally buried more than 1,000 years ago on Mexico’s Yucatán peninsula, the vessels also contain chemical traces present […]

Scientists identify nutrient that helps prevent bacterial infection

How to identify heat-stressed corals

Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study. “This is similar to a blood test to assess human health,” said senior author Debashish Bhattacharya, a Distinguished Professor in the […]

Following three years of cliff surveys in and near the coastal city of Del Mar, Calif., they […]

Scientists identify electronic and structural dynamics of catalytic centers in single-Fe-atom materials

The identification of the electronic and structural dynamics of catalytic centers in single-Fe-atom material by Operando Mossbauer spectroscopy. Credit: LI Xuning Single-atom catalyst (SAC) is a conceptual bridge between homo- and heterogeneous catalysis. It offers new opportunities for capturing the reaction intermediates by identifying the active sites, and even monitoring the dynamic behaviors of both […]
