A collaboration of scientists from NASA and Brazilian research institutions has produced a detailed picture of groundwater change across Brazil. The images reveal significant declines in some of the aquifers that are critical to one of the world’s largest agricultural producers. In the study, published June 3 in Science Advances, researchers used artificial intelligence to […] The post NASA Satel…

Accurate evaluation of rock mechanical properties in shale reservoirs is essential for optimizing hydraulic fracturing design and achieving efficient development. To address the challenges in conventional petrophysical evaluation caused by complex mineral composition and strong heterogeneity of shale in the Qingshankou Formation, Songliao Basin, a novel well logging evaluation framework based on …

The interaction between Land Surface Temperature (LST) and albedo plays a crucial role in regulating surface energy dynamics and environmental variability. This study presents the first comprehensive, nation-scale diagnostic analysis of the LST-albedo relationship in Iran, using daily MODIS MCD43A4 and MOD11A1 datasets spanning 8035 days from 1 January 2001, to 31 December 2022. Data preprocessin…

Finding Balance in Earth's Reflected Sunlight: How a simple wonder led to the discovery of Earth's unique and persistent albedo symmetry in the East-West.

Chemical traces preserved in ancient rocks indicate that marine environments were deteriorating long before the catastrophe that wiped out vast numbers of species at the end of the Triassic period, around 201 million years ago. The post Ancient Oceans Began Losing Oxygen Millions of Years before End-Triassic Mass Extinction appeared first on Sci.News: Breaking Science News .

Computer simulations have uncovered a new manganese compound that could exist deep in Earth’s mantle and may be connected to the process that gave our atmosphere oxygen

The long-offset transient electromagnetic method (LOTEM) offers a large depth of investigation and high sensitivity to subsurface resistivity variations, making it valuable for deep resource exploration, oil and gas prospecting, and engineering investigations. As exploration targets move to greater depths, increasingly undulating surface and subsurface interfaces and more complex structural setti…

Scientists discovered that Antarctica’s ice sheet became dramatically more climate-sensitive after crossing a critical threshold one million years ago. A new study published in Nature Geoscience suggests that Antarctica’s massive ice sheet underwent a major change about one million years ago, becoming far more responsive to shifts in Earth’s climate. The research, led by scientists [...]

Pleased to share our Springer Nature publication exploring advanced hydrodynamics, environmental processes, and emerging Earth science challenges. The book highlights scientific approaches for understanding complex environmental systems and sustainable solutions.

The sedimentation of volcanic ash produced by explosive volcanic eruptions is commonly modelled as being governed by particles falling individually. However, collective settling processes, such as settling-driven gravitational instabilities can shorten the atmospheric residence time of ash. These instabilities generate downward-propagating plumes known as fingers that descend faster than the term…

IntroductionThe petroleum basin system in Northeast China is characterized by the Songliao Basin and its Mesozoic–Cenozoic peripheral small-to medium-sized basins. With escalating exploration challenges and operational costs in the mature Songliao Basin, strategic attention has shifted to evaluating hydrocarbon potential in these under-explored peripheral basins to address regional energy securit…

Nature Communications, Published online: 29 May 2026; doi:10.1038/s41467-026-73875-7 Experiments show that grains returned from asteroid Ryugu can start changing within weeks on Earth. Iron-sulfur minerals alter first, damaging nearby minerals and organic matter. The results show why returned samples must be kept cold and protected.

Our planet's liquid iron outer core is slowly giving up its secrets to a trio of satellites launched by ESA in 2013. Called Swarm, the three probes have been studying Earth's magnetic field at the source. In the process, they've revealed startling changes in a molten layer region 2,200 kilometers beneath the Pacific Ocean. In 2010, material in that area of Earth's outer core changed direction. In…

Subglacial topography is critically important for simulating ice-sheet evolution and projecting sea-level contributions. However, the subglacial topography of the Antarctic Ice Sheet is sparsely measured. Obtaining a gridded topography map used in ice-sheet simulations requires interpolating the measurements or inverting topography from observations of ice velocity and surface elevation. Traditio…
