A Curtin University researcher has solved a nearly 100-year-old riddle by discovering that Egyptian desert glass was created by a meteorite impact, rather than atmospheric airburst, in findings that have implications for understanding the threat posed by asteroids. Published in the leading journal Geology, the research examined tiny grains of the mineral zircon in samples ...
Researchers recently discovered a 3900-mile-long ice corridor on Saturn’s largest moon Titan. The geological formation length is roughly 40 percent of Titan’s circumference. The structure was identified by scientists using data recorded by NASA’s Cassini spacecraft. Titan’s ice corridor Studying Titan’s surface is usually a difficult task since the moon is covered with several layers ...
Computers have had a revolutionary effect on humanity, advancing societies like no other technology has done before. However, all computing technology until now has been dependent on silicon transistors that use electrons for calculations. Scientists are now looking to manipulate photons so that they can build far more powerful processors through quantum computing. Quantum computing ...
Statistical analysis of fossil data shows that it is unlikely that Australopithecus sediba, a nearly 2-million-year-old apelike fossil from South Africa, is the direct ancestor of Homo, the genus to which modern-day humans belong. The research by paleontologists from the University of Chicago, published in Science Advances, concludes by suggesting that Australopithecus afarensis, of the famous “Lucy” skeleton, is still ...
A study from the University of Texas at Austin is the first published in a scientific journal to take an in-depth look at the challenging geologic conditions faced by the crew of the Deepwater Horizon drilling rig and the role those conditions played in the 2010 disaster. The well blowout killed 11 people and spewed ...
A recently documented stand of bald cypress trees in North Carolina, including one tree at least 2,624 years old, are the oldest known living trees in eastern North America and the oldest known wetland tree species in the world. David Stahle, Distinguished Professor of Geosciences, along with colleagues from the university’s Ancient Bald Cypress Consortium ...
Radioactive carbon released into the atmosphere from 20th-century nuclear bomb tests has reached the deepest parts of the ocean, new research finds. A new study in AGU’s journal Geophysical Research Letters finds the first evidence of radioactive carbon from nuclear bomb tests in muscle tissues of crustaceans that inhabit Earth’s ocean trenches, including the Mariana Trench, home to the ...
Approximately every two Earth years, when it is summer on the southern hemisphere of Mars, a window opens: Only there and only in this season can water vapor efficiently rise from the lower into the upper atmosphere. There, winds carry the rare gas to the North Pole. While part of the water vapor decays and ...
Even thousands of years ago people wore clothing with colorful patterns made from plant- and animal-based dyes. Chemists from Martin Luther University Halle-Wittenberg (MLU) have created new analytical methods to examine textiles from China and Peru that are several thousand years old. In the scientific journal Scientific Reports, they describe their new method, which can ...
Humans settled in southwestern Amazonia and even experimented with agriculture much earlier than previously thought, according to an international team of researchers. Jose Capriles, assistant professor of anthropology, said: “We have long been aware that complex societies emerged in Llanos de Moxos in southwestern Amazonia, Bolivia, around 2,500 years ago, but our new evidence suggests that humans ...
