Earthquakes in the Black Rock Desert are rare and capturing the seismic recordings from these earthquakes provides a glimpse into the volcanic system of the Black Rock Desert that, while not showing any signs of erupting, is still active.
NUS historian of science Dr John van Wyhe has co-published a groundbreaking new book on Charles Darwin which shows for the first time the extent of his cultural impact over the past 160 years. A decade in the making, this volume demonstrates that Darwin is the most influential scientist who has ever lived, having the most species named after him and he is also the most translated scientist in history.
A dozen Sandia National Laboratories employees volunteer to go off the beaten trail and give back to their community by participating in wilderness searches and rescues. As members of the Albuquerque Mountain Rescue Council, they use their technical expertise to solve the complex challenges involved in finding lost hikers and hoisting injured rock climbers to safety.
Radioactive Cesium expected to be contained in the forest
Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study in Science Advances raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth's evolving oxidation state. These signals aren't the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis.
A new study using leading edge technology has shed surprising light on the ancient habitat where some of the first dinosaurs roamed in the UK around 200 million years ago.
Spring snowmelt in the Alps is occurring earlier in the year due to climate change and as a result triggering abrupt deviations in mountain ecosystems. These changes could negatively affect the functioning of these valuable ecosystems.
The new era of space exploration features two Stony Brook University faculty members as part of the development of NASA’s Mars2020 Perseverance rover that recently landed. Distinguished Professor Scott McLennan and Associate Professor Joel Hurowitz both worked on the PIXL (Planetary Instrument for X-ray Lithochemistry) that is attached to the arm of the rover. The PIXL is a micro-focus X-ray fluorescence instrument that rapidly measures elemental chemistry by focusing an X-ray beam to a tiny spot on the target rock or soil, analyzing the induced X-ray fluorescence. Both professors have been working on Mars missions with NASA since 2004.
There are millions of unplugged oil wells in the United States, which pose a serious threat to the environment. Using drones, researchers from Binghamton University, State University of New York have developed a new method to locate these hard-to-locate and dangerous wells.
The last complete reversal of the Earth's magnetic field, the so-called Laschamps event, took place 42,000 years ago.
A research team including the geobiologist Dr. Helge Missbach from the University of Cologne has detected organic molecules and gases trapped in 3.5 billion-year-old rocks.
Experimental microbially assisted chemolithotrophy provides an opportunity to trace the putative bioalteration processes of the Martian crust. A study on the Noachian Martian breccia Northwest Africa (NWA) 7034 composed of ancient (ca. 4.5 Gyr old) crustal materials from Mars, led by ERC grantee Tetyana Milojevic from the Faculty of Chemistry of the University of Vienna, now delivered a unique prototype of microbial life experimentally designed on a real Martian material. As the researchers show in the current issue of "Nature Communications Earth and Environment", this life of a pure Martian design is a rich source of Martian-relevant biosignatures.
PNNL researchers discover a new route to forming complex crystals
Drilling a 270,000-year old core from a Tasmanian lake has provided the first Australian record of a major global event where the Earth's magnetic field 'switched '- and the opportunity to establish a precedent for developing new paleomagnetic dating tools for Australian archaeology and paleosciences.
Advances in astronomical observations have resulted in the discovery of an extraordinary number of extrasolar planets, some of which are believed to have a rocky composition similar to Earth. Learning more about their interior structure could provide important clues about their potential habitability. Led by Lawrence Livermore National Laboratory (LLNL), a team of researchers aims to unlock some of these secrets by understanding the properties of iron oxide – one of the constituents of Earth’s mantle – at the extreme pressures and temperatures that are likely found in the interiors of these large rocky extrasolar planets.
Rivers and lakes at high latitudes are considered to be major sources for greenhouse gas emissions to the atmosphere, but these losses are poorly constrained.
How did rocks rust on Earth and turn red? A Rutgers-led study has shed new light on the important phenomenon and will help address questions about the Late Triassic climate more than 200 million years ago, when greenhouse gas levels were high enough to be a model for what our planet may be like in the future.
Researchers from the University of Delaware are part of a team studying the impact climate change and resulting sea level rise is having on the soil underneath coastal military bases. The study is funded by a $3.79 grant from the U.S. Department of Defense.
