An aerial view of a large t-shaped landslide in the midst of a lush green landscape

New Permafrost Landslides Identified in Canada

Researchers identified permafrost detachment slides in Canada’s Northwest Territories.
The landslides contain large blocks of frozen material, unlike typical thaw-slurry failures.
The study links the phenomenon to long-term effects of wildfire in thin-permafrost terrain.
The events may signal an emerging climate-related hazard for northern landscapes.

Oklahoma’s Ames Crater May Date to a Mass Extinction

Ames crater is about 10 miles wide and buried beneath northwestern Oklahoma.
New zircon evidence dates the impact to roughly 370 million years ago.
The previous estimate placed the crater near the 467-million-year-old Ordovician meteor event.
The new date overlaps the Frasnian-Famennian mass extinction interval but does not prove causation.

Scientists create new statewide surface geologic map of Nebraska

Nebraska Gets Its First Statewide Surficial Geologic Map

Researchers Paul Hanson and Matthew Joeckel of the University of Nebraska–Lincoln's Conservation and Survey Division produced the first statewide surficial geologic map of Nebraska.
The project was carried out in coordination with the U.S. Geological Survey, which reached out to the university and has published the map and its data online.
The map is published at a 1:500,000 scale, the first Nebraska surficial map available at a consistent statewide scale.
The paper appears in the Journal of Maps and explains the project's methodology and key findings.

Did Scientists Just Discover Giant Supermountains? | Unveiled | WatchMojo (via www.watchmojo.com)

Buried Antarctic 'Supermountains' Tied to the Explosion of Complex Life

A new examination of tiny ancient rocks points to a colossal mountain range built during the assembly of the supercontinent Gondwana roughly 600 million years ago.
The range, described as primordial supermountains, is now largely buried beneath Antarctica and no longer stands as visible peaks.
Researchers say the Gondwanan supermountains helped set the stage for all modern complex life, making a geological feature central to the history of biology.
The same science roundup covered a study proposing that Venus once had a moon that spiraled inward and was destroyed, possibly contributing to the loss of surface water and a runaway greenhouse state.

Mount Toba’s giant eruption may not have pushed humanity to the brink

Researchers found evidence that Toba’s cooling lasted under two years and was about half a degree.
The result challenges claims that the eruption nearly wiped out early humans.
The study highlights how difficult it is to resolve short volcanic winters in sediment records.

Venus Rift Valleys Suggest the Planet Is Still Active

ETH Zurich researchers used high-resolution 3D simulations to model Venusian rift valleys.
The results suggest some rifts may have formed about 100 million years ago.
The study supports the view that Venus may still be geologically active.

NASA’s Curiosity rover finds a mysterious honeycomb landscape on Mars

Curiosity spots vast honeycomb fracture field on Mars

Curiosity found a broad field of honeycomb-like polygonal fractures in Valle Grande.
The patterns extend across the valley floor and up a nearby butte called Miraflores.
Scientists are testing whether drying mud, thermal cycling, compression, or multiple processes created the formation.

Huge crater in Australia may be the oldest impact structure on Earth

Australian crater study revives debate over Earth’s oldest impact site

Researchers say new mineral dating places the North Pole Dome impact at about 3.02 billion years ago.
The result would make the Western Australia site older than Yarrabubba, the current oldest reliably dated crater.
Other researchers have disputed earlier age claims for the structure and questions remain about interpretation.

Scientists have known about the hydrothermal system created by the Chicxulub impact. These types of systems could be where prebiotic chemistry got a boost, leading to the appearance of the first simple life. But for that to happen, the system needed to last for a long time. New research says it lasted 8 million years, much longer than previous estimates. Image Credit: Victor O. Leshyk

Chicxulub’s heat may have kept a life-friendly underground system active for 8 million years

Researchers say the Chicxulub impact generated a hydrothermal system active for about 8 million years.
A longer-lived system increases the time available for prebiotic chemistry and possible microbial colonization.
The findings strengthen the case for studying impact craters as potential habitable environments on Earth and other worlds.

Jabal al Fāyah: A Limestone Ridge Reveals the UAE's Watery Past and Early Human Survival

Jabal al Fāyah is a limestone ridge in the UAE, once submerged under the Tethys Sea.
The ridge stands 412 meters above sea level and traps sand dunes to its west.
The area holds evidence of early human habitation, with stone tools dating to the Paleolithic.

Venus, as seen by NASA’s Magellan spacecraft

New 3D Maps of Venus’s Coronae Point to a More Active Interior

Researchers modeled Venus’s largest coronae using Magellan radar, gravity and topographic data.
The team says coronae vary too much to come from one formation mechanism.
Possible warm mantle upwellings were identified beneath 52 coronae.
Current gravity data may miss signs of active tectonics on Venus.

Earth’s core is as hot as the sun’s surface, and scientists had to infer it indirectly

Earth’s core is estimated at roughly 5,000 to 5,500 degrees Celsius.
The core includes a liquid outer layer and a solid inner layer.
Scientists infer the temperature through seismic data, meteorites and high-pressure iron experiments.

Hydrogen From Rocks Could Pair Clean Fuel Production With CO2 Storage

Researchers say a common rock type can generate hydrogen while storing CO2 in lab studies.
The concept could potentially combine hydrogen production, carbon sequestration, and geothermal energy.
Field trials are the next step, and economic viability remains unproven.

Scientists discover massive natural hydrogen source beneath Canada

Canada’s Ancient Rocks May Be Releasing a Vast New Source of Natural Hydrogen

Researchers directly measured hydrogen escaping from ancient rocks in Ontario mine boreholes.
The study suggests sustained underground flows could make natural, or white, hydrogen a viable energy resource.
The work also proposes a new strategy for exploring similar hydrogen systems elsewhere.

Mars likely had water, but not tides strong enough to sculpt much of its shoreline record

Researchers modeled tidal behavior in ancient Martian waters at two rover-linked sites.
Maximum tide speeds were estimated at roughly 0.01 meters per second.
The study suggests tides were usually a secondary, not primary, factor in sediment formation.
