A PMP-inspired Evaluation Framework for Assessing Deep-Learning Earth System Models
arXiv:2604.06567v3 Announce Type: replace Abstract: In recent years, Deep-Learning Earth System Models (DL-ESMs) have emerged as promising, computationally efficient complements to traditional Earth system models. Here, we present an evaluation framework for testing DL-ESMs from an Earth system model-development perspective using standardized diagnostics from the PCMDI Metrics Package (PMP). This framework allows DL-ESMs, including Ai2's ACE2 and Google's NeuralGCM, to be assessed with...
Why do Venus and Jupiter meet up in the sky so often? It's a symptom of a solar system that supports life on Earth
Why do Venus and Jupiter meet up in the sky so often? It's a symptom of a solar system that supports life on Earth "Orbital dynamics allows you to start to think about all those fun, different aspects of what makes our planet habitable, and ask how normal it is to have a habitable planet." Shortly after sunset on June 9, Venus and Jupiter will look very close together, in what is known as a planetary conjunction.
Science Earth: Towards A Planet-Scale Operating System for AI-Native Scientific Discovery
arXiv:2606.01316v1 Announce Type: new Abstract: Scientific discovery demands intelligence, perseverance, and serendipity across vast search spaces. Today, top scientific capabilities remain siloed--one AI system for biological analysis, another for clinical reasoning, mathematical derivation, or materials simulation--and no pre-designed team can anticipate every skill a question will need. Science Earth is a planet-scale scientific runtime in which any capability--a simulation cluster, a...
Climate network characterization of the AMOC edge state
arXiv:2606.08623v1 Announce Type: new Abstract: The Atlantic Meridional Overturning Circulation (AMOC) has been identified as a tipping element in the Earth system. Under the current climate change scenarios, it is urgent to develop robust methods for determining the probability of future AMOC transitions. Recent studies using an Earth System Model of Intermediate Complexity (EMIC) have revealed the importance of an AMOC edge state, located on the boundary of the attraction basin of the...
Astronomers discover exoplanets with magnetic fields
Astronomers discover exoplanets with magnetic fields WASHINGTON: Based on the behaviour of winds on seven large and hot gas exoplanets, astronomers have obtained the strongest evidence to date that planets beyond our solar system possess magnetic fields, like Earth and five other planets in our solar system. The finding, based on observations by telescopes in Chile and Hawaii, deepens the understanding of exoplanets by showing that at least some share an important characteristic present in...
Space station dust maps slash climate uncertainty over iron-rich particles
Space station dust maps slash climate uncertainty over iron-rich particles Lisa Lock Scientific Editor Robert Egan Associate Editor New research from a team of scientists led by Cornell is transforming how researchers understand one of the atmosphere's most abundant and least understood constituents: mineral dust. Mineral dust, composed of tiny particles lifted from arid regions including the Sahara, Middle East and East Asia, plays a complex role in Earth's climate system. These particles...
Viability of Tensor Train Methods for Geophysical Fluid Dynamics
Announce Type: new Abstract: Tensor train (TT) methods have recently gained popularity for accelerating the solving of systems of PDEs. Here, we evaluate the performance of TT methods in the context of geophysical fluid dynamics (GFD) using the shallow water equations and a discretization scheme employed by the ocean component of the Energy Exascale Earth System Model (E3SM). Through a suite of four test cases of increasing complexity, we evaluate TT methods in terms of how much TT is able...

At the Origins of Electroculture: A Retrodictive Modelling of Bertholon's 18th-Century Electrovegetometer in the Pre-Corona Regime
arXiv:2606.10433v1 Announce Type: new Abstract: Pierre-Nicolas Bertholon's 18th-century electrovegetometer was conceived to harness "atmospheric electricity" for plant growth, yet its physical capabilities have never been quantified within the context of today's understanding of the Earth's atmospheric electric system. This study addresses the lack of quantitative assessment of such historical "electroculture" device and its plausible influence on the near-canopy electrical environment. It...
Scientists discover ancient single-celled ancestors still live on in your blood
Scientists uncovered evidence that human blood cells may trace their origins back to single-celled ancestors that lived 700 million years ago. By rebuilding the evolutionary family tree of blood cells, the team revealed how today’s immune system grew from some of Earth’s earliest life forms.
