Real-time measurements provide missing insight into chemical separations to recover cobalt, a critical raw material used to make batteries and magnets for modern technologies. Results track the dynamics of molecules designed to grab cobalt from solutions containing a mixture of similar species.
Geologists publish new findings on carbonate melts in Earth's mantle

Geologists have discovered how carbon-rich molten rock in the Earth's upper mantle might affect the movement of seismic waves.
Researchers discover how a protein reduces the adverse impact of water loss in cells
A University of Houston College of Medicine researcher has found how a protein inside the body reduces the adverse effects of hypertonicity, an imbalance of water and solutes inside cells. Hypertonicity causes cell shrinkage and eventual cell death. The findings could have implications for a wide range of illnesses including edema from brain tumors, autoimmune diseases and kidney damage.
Tropical Storm Isaias drives wild weather up Interstate 95
At least four people were killed as Tropical Storm Isaias spawned tornadoes and dumped rain Tuesday along the U.S. East Coast after making landfall as a hurricane in North Carolina, where it caused floods and fires that displaced dozens of people.
Gulf of Mexico's 'dead zone' much smaller this year
Tropical weather stirred up the Gulf of Mexico, reducing this year's dead zone off Louisiana's coast to the third-smallest ever measured, the scientist who has measured it since 1985 said Tuesday.
Surface of Mars shows scars of glaciers just like Canada's High Arctic: study
The deep valleys scarred into the surface of Mars under thick sheets of ice show that the planet once mirrored the Canadian High Arctic, says a new...
Terrawatch: lasting legacy of Taiwan's 2009 typhoon season
Typhoon Morakot left country with more quakes after changing stress pattern in Earth’s crustEleven years ago, Typhoon Morakot slammed into Taiwan, deluging the country with 3,000 litres of rain per square metre in three days. Catastrophic flooding and landslides followed and more than 600 people died.It is considered one of the worst tropical cyclones in Taiwan’s recorded history. But that...
Size of fly's eyes and nose reflect its behavior during mating and habitat preferences, says study
The size of a fly's eyes and nose reflect both its behavior during mating and its habitat preferences, according to a new study published today in eLife.
Ultrafast lasers probe elusive chemistry at the liquid-liquid interface
Real-time measurements captured by researchers at the Department of Energy's Oak Ridge National Laboratory provide missing insight into chemical separations to recover cobalt, a critical raw material used to make batteries and magnets for modern technologies.
NASA's Aqua satellite shows two views of the Apple Fire
NASA's Aqua satellite took images of the Apple Fire as it continued to spread north across the head of the Mill Creek Canyon, and east into the San Gorgonio Wilderness near San Bernardino, Calif. on Aug. 03, 2020. The fire is now burning into more wilderness (where vegetation is sparse) than wooded area limiting the intensity of the fire due to a lack of fuel. Continued fire activity is due to the...
Geologists publish new findings on carbonate melts in Earth's mantle
Geologists from Florida State University's Department of Earth, Ocean and Atmospheric Science have discovered how carbon-rich molten rock in the Earth's upper mantle might affect the movement of seismic waves.
Scientists propose a novel method for controlling fusion reactions
Scientists have found a novel way to prevent pesky magnetic bubbles in plasma from interfering with fusion reactions—delivering a potential way to improve the performance of fusion energy devices. And it comes from managing radio frequency (RF) waves to stabilize the magnetic bubbles, which can expand and create disruptions that can limit the performance of ITER, the international facility under...
AI may offer a better way to ID drug-resistant superbugs
Biomedical engineers at Duke University have shown that different strains of the same bacterial pathogen can be distinguished by a machine learning analysis of their growth dynamics alone, which can then also accurately predict other traits such as resistance to antibiotics. The demonstration could point to methods for identifying diseases and predicting their behaviors that are faster, simpler,...
