Underground pipelines that transport oil and gas are very important engineering communications worldwide. Some of these underground communications are built and operated in earthquake-prone areas. The research shows that current methods used for calculating stress received by the underground pipelines during an earthquake are incorrect.
South Korea's Ulsan National Institute of Science and Technology (UNIST) has proposed a satellite-aided drought monitoring method that can adequately represent the complex drought conditions into a single integrated drought index.
In order to get a sense of what our future may hold, scientists have been looking to the deep past. Now, new research from the University of Massachusetts Amherst, which combines climate, ice sheet and vegetation model simulations with a suite of different climatic and geologic scenarios, opens the clearest window yet into the deep history of the Antarctic ice sheet and what our planetary future might hold.
Aptly called Earth's "Third Pole," the Himalayan region is home to the largest ice mass outside of the planet's polar regions.
A new paper published in the Journal of Near Eastern Studies presents the results of and images from the resuming of the archaeological seasons in the Mons Smaragdus region in the Egyptian Eastern Desert. During the 1990s a team from the "Berenike Project" started to survey the area and conducted the first excavations, focusing on the main site identified, Sikait, where the archaeological seasons resumed in January of 2018 and January 2020.
Satellite views of Earth's major river systems reveal their familiar treelike drainage patterns. The pattern - called dendritic - and its prevalence suggests that it may be the optimal state in which rivers exist. Challenged by the knowledge that numerical models of drainage evolution have yet to substantiate this assumption, researchers are now thinking of rivers as existing in a persistent reorganizational state instead of being in a set, stable configuration. Understanding this has implications for land use and infrastructure management decisions.
Ethiopia may produce less specialty coffee and more rather bland tasting varieties in the future. This is the result of a new study by an international team of researchers that looked at the peculiar effects climate change has on Africa's largest coffee producing nation. Their results are relevant both for the country's millions of smallholder farmers, who earn more on specialty coffee than on ordinary coffee, as well as for baristas and coffee aficionados around the world.
Researchers compared lake sediment, tree ring data and archaeological evidence to reconstruct a 1,200 history of fire, climate, and human activity of the Fish Lake Plateau, a high-elevation forest in central Utah in the U.S. They found that Indigenous people used small, frequent fires, a practice known as cultural burning, which reduced the risk for large-scale wildfire activity in mountain environments even during periods of drought more extreme and prolonged than today.
In a new study, Dr. LU Xiankai and his colleagues from the South China Botanical Garden (SCBG) of the Chinese Academy of Sciences (CAS) found that tropical forests can capture carbon dioxide (CO2) into soils and thus reduce emitted CO2.
A new study verifies the age and origin of one of the oldest specimens of Homo erectus--a very successful early human who roamed the world for nearly 2 million years. In doing so, the researchers also found two new specimens at the site--likely the earliest pieces of the Homo erectus skeleton yet discovered.
