Snow Science in Support of Our Nation's Water Supply

Researchers have completed the first flights of a NASA-led field campaign that is targeting one of the biggest gaps in scientists’ understanding of Earth’s water resources: snow. NASA uses the vantage point of space to study all aspects of Earth as an interconnected system

Ancient Jars Found in Judea Reveal Earth's Magnetic Field is Fluctuating, Not Diminishing

Albert Einstein considered the origin of the Earth’s magnetic field one of the five most important unsolved problems in physics. The weakening of the geomagnetic field, which extends from the planet’s core into outer space and was first recorded 180 years ago, has raised c

Eating Fish? Then You're Eating Plastic, Too

Synthetic fleece is something of a modern miracle. It keeps us warm and cozy, is easily cleaned and doesn’t even require we harm any animals to make it. Perfect, right? Well, every miracle comes with a price. It turns out that every time we wash one fleece pullover or jacket, we’re se

Bigger May Not Be Better When It Comes to Mississippi River Diversions

River diversions are a common coastal wetland restoration tool, but recent research, conducted by U.S. Geological Survey in collaboration with researchers in Louisiana State University’s Department of Civil and Environmental Engineering and the LSU AgCenter, has shown that large-scale

Banned chemicals from the 70s found in deepest reaches of the ocean

A study, led by Newcastle University’s Dr Alan Jamieson has uncovered the first evidence that man-made pollutants have now reached the farthest corners of our earth. Sampling amphipods (pictured) from the Pacific Ocean’s Mariana and Kermadec trenches – which are over 10 kilometr

Desert Songbirds May Face Expanding Threat of Lethal Dehydration

AMHERST, Mass – A new study of songbird dehydration and survival risk during heat waves in the United States desert Southwest suggests that some birds are at risk of lethal dehydration and mass die-offs when water is scarce, and the risk is expected to increase as climate change advan

Marine bacteria produce an environmentally important molecule with links to climate

Scientists from the University of East Anglia and Ocean University China have discovered that tiny marine bacteria can synthesise one of the Earth’s most abundant sulfur molecules, which affects atmospheric chemistry and potentially climate. This molecule, dimethylsulfoniopropionate (

Important to maintain a diversity of habitats in the sea

Researchers from University of Gothenburg and the Swedish University of Agricultural Sciences (SLU) show that both species diversity and habitat diversity are critical to understand the functioning of ecosystems. Marine shallow-water environments, where this research was performed, ar
