Theoretical model explains the anomalous properties of water in extreme conditions
Water, a molecule essential for life, has unusual properties—known as anomalies—that define its behavior. However, there are still many enigmas about the molecular mechanisms that would explain the anomalies that make the water molecule unique. D.....»»
Scientists compile library for evaluating exoplanet water
By probing chemical processes observed in the Earth's hot mantle, Cornell scientists have started developing a library of basalt-based spectral signatures that not only will help reveal the composition of planets outside of our solar system but could.....»»
New York drought conditions fan flames, spur water saving
New York has urged its 8.5 million residents to save water as America's biggest city endures an unprecedented period without significant rainfall, creating potentially dangerous drought conditions and fanning the flames of deadly wildfires......»»
Colorado River basins could face tipping point, drought study warns
Water from Colorado's West Slope basins plays a vital role in supporting the economy and natural environment across seven western U.S. states, but a new study finds that even under modest climate projections, the basins face a potential tipping point.....»»
Metagenomic profiling method with enhanced precision uses fewer computing resources
Researchers at Carnegie Mellon University and the University of Toronto have developed a new k-mer sketching metagenomic profiler, called sylph, that allows scientists to analyze genomic data more quickly and precisely than other profilers......»»
Meteorite contains evidence of liquid water on Mars 742 million years ago
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth somewhere near Purdue University and is one of the few meteorites that can be traced.....»»
