I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Ancient mountains recorded in Antarctic sandstones reveal potential links to global events” Credit: University of Wisconsin Oshkosh A new analysis of sandstones from Antarctica indicates there may be important links between the generation of mountain belts and major transitions in Earth’s atmosphere and oceans. A team of researchers analyzed the chemistry of tiny zircon grains…
“#Application of machine learning can optimize hurricane track forecast” Researchers say a machine learning technique could help meteorologists provide more accurate medium-term forecasts and issue timely warnings to people who could be affected by these potentially deadly storms.

Geologists from Florida State University’s Department of Earth, Ocean and Atmospheric Science have discovered how carbon-rich molten…
“#How the seafloor of the Antarctic Ocean is changing—and the climate is following suit” 24 million years ago – transition from the Oligocene to the Miocene Credit: Alfred-Wegener-Institut, Katharina Hochmuth The glacial history of the Antarctic is currently one of the most important topics in climate research. Why? Because worsening climate change raises a key…
“#Scientists reveal roles of wind stress and subsurface cold water in the second-year cooling of the 2017/18 La Nina” Credit: CC0 Public Domain To improve our understanding of the physical mechanisms involved and provide an observational basis for model validation, Dr. Licheng Feng (National Marine Environmental Forecasting Center) and colleagues set out to diagnose the…
“#Improving the accuracy of typhoon forecasts with radar data assimilation” Credit: Pixabay/CC0 Public Domain Gales and rainstorms brought by landfalling typhoons cause extensive casualties and loss of property every year in many coastal areas of the western Pacific. As such, predicting the track and precipitation of typhoons has always been a top priority of weather…
“#Germany-wide rainfall measurements via the mobile network” 48-hour showcase of accumulated precipitation measured using the radar network operated by the German Meteorological Service (DWD) compared against the CML-derived rainfall chart. Credit: Graf et al., 2020 Whether in flood early-warning systems or in agriculture—rainfall measurements are of great importance. However, there is a lack of accurate…
“#Iron-rich meteorites show record of core crystallization in system’s oldest planetesimals” A beautiful illustration of the Widmanstatten pattern, which is characteristic of iron meteorites. Credit: Peng Ni. New work led by Carnegie’s Peng Ni and Anat Shahar uncovers new details about our Solar System’s oldest planetary objects, which broke apart in long-ago collisions to form…
“#Wildfires can poison drinking water: Here’s how communities can be better prepared” Survivors left everything to flee the Camp Fire’s path. Credit: Andrew Whelton, Purdue University In recent years wildfires have entered urban areas, causing breathtaking destruction. The 2018 Camp Fire in Paradise and Butte County, California was the deadliest and most destructive fire in…
“#Scientists evaluate spatiotemporal characteristics of glacier service value in Qilian Mountains” Distribution of glaciers in the Qilian Mountains. Credit: SUN Meiping Glaciers are an important component of the cryosphere. They are considered to be a sensitive indicator of climate change. Glaciers and their meltwater play an important role in the regulation of river runoff in…
