Researchers at the University of Iowa and the United States Geologic Survey report data gathered by orbiting satellites can yield more information about destructive earthquakes and can improve aid and humanitarian response efforts. The researchers looked at satellite data from several recent, large-magnitude earthquakes.
New research by a University of Guelph physicist suggests most of Earth's heavy metals were spewed from a largely overlooked kind of star explosion called a collapsar.
A new study from researchers at the Woods Hole Oceanographic Institution (WHOI) and Harvard University may help settle a long-standing question--how small amounts of organic carbon become locked away in rock and sediments, preventing it from decomposing. Knowing exactly how that process occurs could help explain why the mixture of gases in the atmosphere has remained stable for so long.
A group of researchers from Japan has recently discovered a novel enzyme from a soil fungus. In their study, they speculate that this enzyme plays important roles in the soil ecosystem, and then describe its structure and action.
Fresh evidence rewrites the understanding of the most intriguing archaeological burial site in western Finland. New DNA technology gives significant information on the bones buried in water. The DNA matches present day Sámi people, who nowadays live far from the site. The question why the bones were buried in water remains a mystery and demands further investigation.
Studying the sediment of a mountain river can reveal thousands of years or more of a waterway's history, including new threats from more frequent wildfires and increased precipitation brought by climate change. Understanding those challenges may provide insight into other waterways, including urban streams like the Cuyahoga River in Ohio, named River of the Year as it marks 50 years since the 1969 fire.
The researchers found in extreme drought conditions that predator nematodes significantly decreased, which led to the growth of root-feeding nematodes.
Pitcher plants growing in wetlands across Canada have long been known to eat creatures -- mostly insects and spiders -- that fall into their bell-shaped leaves and decompose in rainwater collected there. But University of Guelph researchers have discovered the vertebrates, salmanders, are also part of their diet. He said pitcher plants may have become carnivorous to gain nutrients, especially nitrogen, that are lacking in nutrient-poor bog soil.
Drone surveys have revealed extreme erosion on the Arctic coastline, highlight the ongoing change in the region in a warming climate.
Certain molecules of iron, when juxtaposed, have been found by Sandia National Labs and Aramco Research Center researchers to cause microscopic holes in steel pipe used for oil transport. This hidden, localized corrosion causes oil pipes to rust unpredictably at rates faster than baselined, interfering with the accuracy of computer models that determine pipe replacement schedules. This problem, which is potentially environmental, may be addressed by changing the microstructure of the steel surface during forging.
