Scientists complete first global survey of freshwater fluctuation

To investigate humans' impact on freshwater resources, scientists have now conducted the first global accounting of fluctuating water levels in Earth's lakes and reservoirs—including ones previously too small to measure ...

ExoMars discovers new gas and traces water loss on Mars

Sea salt embedded in the dusty surface of Mars and lofted into the planet's atmosphere has led to the discovery of hydrogen chloride—the first time the ESA-Roscosmos ExoMars Trace Gas Orbiter has detected a new gas. The ...

Smart site selection can make hydropower greener

Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, ...

How nearby galaxies form their stars

Stars are born in dense clouds of molecular hydrogen gas that permeates interstellar space of most galaxies. While the physics of star formation is complex, recent years have seen substantial progress towards understanding ...

Nebraska anglers are creatures of habit

Fishing behavior of Nebraska anglers may be more predictable than previously thought, says a new paper published in the Ecological Society of America's journal Ecological Applications. Seven fishing spots across the state ...

Simulator for drilling at depths up to 5,000 meters

To tap into geothermal reservoirs, boreholes must be drilled deeply into the earth's crust. Due to the extreme pressures and temperatures involved, this is expensive and time consuming. A research team from Fraunhofer IEG ...
