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.

An illustration of Earth splitting apart, showing its inner layers as they glow orange and white, getting hotter and smaller.

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.

USGS Finds Major Lithium Potential in the Appalachians

USGS researchers estimate the Appalachians contain about 2.5 million tons of lithium.
The deposits occur in pegmatites across a broad region from Alabama to Maine.
The finding could strengthen domestic supply options while intensifying environmental and land-use debates.

A new tectonic plate boundary could be forming in southern Africa

Hot-Spring Gases Suggest a New Rift May Be Opening Beneath Southern Africa

Researchers found mantle-signature gases in hot springs and geothermal wells in Zambia.
The results suggest the Kafue Rift is geologically active and may involve a tear in tectonic plates.
The area could offer insights into the earliest stages of continental breakup.

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.

Yellowstone May Be Driven More by Crustal Shifts Than a Deep Magma Plume, Study Suggests

New research suggests Yellowstone’s volcanic activity may be driven more by crustal shifts than a deep magma source.
The finding challenges a long-running debate over whether a mantle plume is the dominant driver.
Researchers say future eruption models will need to account for the revised plumbing picture.

Earth is splitting open beneath the Pacific Northwest, scientists say

Scientists Capture a Cascadia Plate Tearing Apart Beneath the Pacific Northwest

Researchers used seismic reflection imaging and earthquake records in Cascadia.
They report the Juan de Fuca plate is splitting into fragments as it subducts.
The finding could refine how scientists think about subduction-zone failure and earthquake behavior.

New Digital Tool Lets You See Where Your Backyard Was Millions of Years Ago

A new paleolatitude tool lets anyone trace where a place sat on Earth over the last 320 million years

Paleolatitude.org lets users trace how a location’s latitude changed over 320 million years.
The tool is built on the Utrecht Paleogeography Model, a decade-long tectonic reconstruction effort.
It offers an accessible way to connect plate motion with climate, fossils, and Earth history.

Mount Etna May Represent a Newly Identified Kind of Volcanism

A new study suggests Mount Etna does not fit the three standard volcano categories.
Researchers say Etna may have formed through a mechanism resembling petit-spot volcanism.
The finding could expand how geologists classify volcanic systems.

Scientists just discovered Africa is closer to breaking apart than we thought

East Africa's Turkana Rift May Be Far Closer to Continental Breakup Than Expected

Researchers say the Turkana Rift crust is thinner than previously recognized.
The study identifies an advanced necking stage associated with continental breakup.
The same tectonic setting may help explain the region's unusually rich fossil preservation.

Mars May Have Preserved an Ancient Ocean Shelf Instead of a Clean Shoreline

A new paper argues Mars preserved a continental shelf-like feature rather than a simple shoreline.
The proposed shelf spans 10.2 million square kilometers.
Known deltas, layered rocks, clays, and candidate shorelines cluster within the region.

Grand Canyon origin debate gets a boost from evidence of a late Miocene Colorado River in the Bidahochi basin

The paper title says late Miocene Colorado River arrival in the Bidahochi basin supports a spillover origin of the Grand Canyon.
The available source text is limited to title and citation metadata, so the interpretation here stays close to that wording.
The study appears to add new timing evidence to a long-running geological debate over canyon formation.

Scientists Say They Have Solved a 5-Million-Year Colorado River Mystery

Phys.org reports geologists have solved a long-standing Colorado River mystery.
The puzzle concerned a roughly 5-million-year gap in the geological record.
The finding could sharpen reconstructions of western North American landscape history.

A Giant Ancient Lake May Explain How the Grand Canyon Began to Form

A new study suggests the Colorado River pooled into a giant lake before spilling downstream.
Researchers argue that spillover may have helped initiate carving of the Grand Canyon.
The interpretation is notable but remains disputed within the scientific debate.

A New Yellowstone Study Challenges the Classic Mantle Plume Explanation

A new paper argues Yellowstone may be powered by crust-opening stresses tied to the long disappearance of the Farallon plate.
The proposal challenges the standard interpretation of Yellowstone as a straightforward mantle plume hotspot.
The study addresses mismatches in eruption chemistry and a gap in volcanic activity between Yellowstone and the Snake River Plain.
Its broader significance lies in showing how ancient tectonic history can shape present-day volcanism.

Natural Hydrogen Is Real, Commercialization Is Not - CleanTechnica

Natural Hydrogen Has Moved Beyond Hype, but the Commercial Case Remains Unproven

Natural hydrogen is no longer just a speculative idea, but reserve proof is still limited.
The sector’s key challenge is converting geological occurrence into sustained commercial output.
A disciplined extractive-industry framework is replacing earlier hype.
