I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Monitoring groundwater changes more precisely” Credit: CC0 Public Domain A new method could help to track groundwater changes better than before. To this end, researchers from Potsdam and Oberlin, Ohio (USA), have compared gravity field data from the GRACE and GRACE-Follow On satellite missions with other measuring methods. They investigated the seasonal water storage in…
“#Evolution after Chicxulub asteroid impact: Rapid response of life to end-cretaceous mass” Lead author Francisco J. Rodríguez-Tovar in Bremen, Germany, working with the K-Pg core from IODP Expedition 364. Credit: Geology and Francisco J. Rodríguez-Tovar The impact event that formed the Chicxulub crater (Yucatán Peninsula, México) caused the extinction of 75% of species on Earth…
“#Scientists discover fault system in southeastern Nepal” U of A graduate student Mike Duvall conducts fieldwork in southeastern Nepal in 2017. Duvall and his supervisor John Waldron were part of an international team of scientists who identified a series of previously unknown faults in the region.

“#Chance of big San Andreas earthquake increased by Ridgecrest temblors, study suggests” Credit: CC0 Public Domain A new study suggests that last year’s Ridgecrest earthquakes increased the chance of a large earthquake on California’s San Andreas fault. The study, published in the Bulletin of the Seismological Society of America on Monday, says there is now…
“#Using math formulas to predict earthquakes” Credit: Unsplash/CC0 Public Domain A team of researchers at Lyell Centre in Edinburgh, has developed a way to use math formulas to help predict when an earthquake is likely to happen. In their paper published in Journal of Geophysical Research: Solid Earth, the group describes translating the movement of…
“#Insights into climate change during origin of dinosaurs” A dinosaur-like reptile leaves muddy footprints along the shoreline of a lake during a rainstorm some 234 million years ago in northwestern Argentina. Credit: Jorge Gonzalez/NHMU The Triassic Period, about 252 to 201 million years ago, was a time of volatile change, particularly during an interval known…
“#Giant A-68 iceberg three years on” A huge iceberg called A-68 calved from the Antarctic Peninsula’s Larsen C ice shelf on 12 July 2017. Three years on, it is in open waters near the South Orkney Islands in the South Atlantic Ocean – about 1050 km from its birthplace. The berg has already lost two…
“#Soil studies can be helpful for border control” A soil tunnel shaft is used to access a tunnel under the U.S.-Mexico border. Credit: University of Illinois at Urbana-Champaign Underground tunnels have been used by warriors and smugglers for thousands of years to infiltrate battlegrounds and cross borders. A new analysis published in the Open Journal…
“#Plate tectonics research rewrites history of Earth’s continents” Credit: Pixabay Curtin University-led research has found new evidence to suggest that the Earth’s first continents were not formed by subduction in a modern-like plate tectonics environment as previously thought, and instead may have been created by an entirely different process. Published in the journal Geology, the…
“#Using sound to study underwater volcanoes” The Hawaiian-Emperor seamount chain (the roughly L-shaped configuration near the center of the image) is about 3,900 miles long. For comparison, that’s the west coast of North America on the right. Credit: NOAA Imagine placing a rock on a piece of suspended cardboard. If the cardboard is strong and…
