Can sound protect eagles from wind turbine collisions?
Every year, bald and golden eagles are killed when they inadvertently fly into wind turbine blades. One possible way to prevent these deaths is to chase the birds away with acoustic signals—sound. To determine what types of sounds are most effective in deterring the birds, researchers at the University of Minnesota and their colleagues tested the behavioral responses of bald eagles to a battery of both natural and synthetic acoustic stimuli.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

New drug could help treat neonatal seizures
A new drug that inhibits neonatal seizures in rodent models could open up new avenues for the treatment of epilepsy in human newborns. Researchers have identified that gluconate—a small organic compound found in fruit and honey—acts as an anticonvulsant, inhibiting seizures by targeting the activity of channels that control the flow of chloride ions in and out of neonatal neurons. A paper describing the research, from an international team of scientists led by Penn State researchers, appears May 15, 2019 in the journal Molecular Brain.

Study finds scientific reproducibility does not equate to scientific truth
Reproducible scientific results are not always true and true scientific results are not always reproducible, according to a mathematical model produced by University of Idaho researchers. Their study, which simulates the search for that scientific truth, will be published Wednesday, May 15, in the journal PLOS ONE.

Machine learning predicts mechanical properties of porous materials
Machine learning can be used to predict the properties of a group of materials which, according to some, could be as important to the 21st century as plastics were to the 20th.

Ice-sheet variability during the last ice age from the perspective of marine sediment
By using marine sediment cores from northwestern Australia, a Japanese team led by National Institute of Polar Research (NIPR) and the University of Tokyo revealed that the global ice sheet during the last ice age had changed in a shorter time scale than previously thought. This study was published on May 10 in the journal Scientific Reports.

Applying precious metal catalysts economically
Researchers at Ruhr-Universität Bochum and the Fritz Haber Institute Berlin have developed a new method of to conserve rare and expensive catalysts and use them sparingly. They enclosed a precious metal salt in tiny micelles, and struck them against a carbon electrode, thus coating the surface with nanoparticles of the precious metal contained in the micelles. At the same time, the team precisely analysed how much of the metal was deposited. The researchers then showed that the electrode coated in this manner could efficiently catalyse the oxygen reduction, which is the limiting chemical process in fuel cells.
