Climate and ocean models use a series of equations to represent complex natural processes. However, the equations used in these models are often derived from limited observations and a series of assumptions.

Earth's oldest crater really is more than 3 billion years old, new study confirms

Phys.org: Earth science - Wed, 06/24/2026 - 17:40

In the Pilbara of Western Australia, some of Earth's oldest rocks lie beneath the sky, as they have for billions of years. They are dark, weathered volcanic rocks, close to 3.5 billion years old, cut by veins and stewed by deep time.

Modeling transport in weakly collisional plasmas using thermodynamic forcing

Physical Review E (Plasma physics) - Wed, 06/24/2026 - 10:00

Author(s): Prakriti Pal Choudhury and Archie F. A. Bott

How momentum, energy, and magnetic fields are transported in the presence of macroscopic gradients is a fundamental question in plasma physics. Answering this question is especially challenging for weakly collisional, magnetized plasmas, where macroscopic gradients influence the plasma's microphysic…

Every time Norway scores, the whole city of Bergen shakes

Phys.org: Earth science - Wed, 06/24/2026 - 03:40

During Norway's first match of the FIFA World Cup against Iraq on June 17, several small vibrations were recorded on the seismometer. A particularly clear signal was observed when Erling Haaland scored.

Oldest known asteroid impact on Earth dated to 3 billion years

Phys.org: Earth science - Tue, 06/23/2026 - 22:00

Curtin University researchers have determined the most precise age yet for the oldest known impact crater on Earth, providing new insight into how meteorite strikes shaped the planet during its earliest history.

How continental shelf seiches triggered flooding following New York and New Jersey hurricanes

Phys.org: Earth science - Tue, 06/23/2026 - 19:09

In 1938 and 1944, two major hurricanes struck Long Island, and after the initial winds subsided, the surges came back unexpectedly hours later, leading observers to wonder whether this was a tsunami. In a study appearing in Continental Shelf Research, scientists at Stevens Institute of Technology explain the phenomenon and warn that it could happen again.

Airflow mystery solved: Heavy rain reshaped airflow through miles of underground tunnels

Successfully operating in a deep underground space requires mitigating two factors: air and water.

Hidden seismicity patterns before large earthquakes uncovered

Phys.org: Earth science - Tue, 06/23/2026 - 13:00

When and where the next large earthquake will strike remains one of the most difficult questions in geoscience. Researchers from the GFZ Helmholtz Center for Geosciences led by Dr. Sadegh Karimpouli and Prof. Dr. Patricia Martínez-Garzón have now—together with international partners—developed a new data-driven approach that can identify characteristic changes in seismic activity before some major earthquakes occur.
