Quantifying Accuracy of an Event-Based Star Tracker via Earth's Rotation
Event-based cameras (EBCs) are a promising new technology for star tracking-based attitude determination, but prior studies have struggled to determine accurate ground truth for real data. We analyze the accuracy of an EBC star tracking system utilizing the Earth's motion as the ground truth for comparison. The Earth rotates in a regular way with very small irregularities which are measured to the level of milli-arcseconds. By keeping an event camera static and pointing it through a ground-base…

Rare deep-sea hydrothermal system discovered in western Pacific produces massive hydrogen emissions
Hydrogen-producing hydrothermal systems in the deep ocean are rare but critical to understanding Earth's internal processes and the conditions that may have fostered life's origins. Now scientists from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) have discovered a massive hydrogen-rich hydrothermal system beneath the western Pacific seafloor, offering a new glimpse into deep-sea serpentinization—a process in which iron- and magnesium-rich rocks chemically react with …

Optimal Multi-Mode Propulsion Mission Design Using Direct Collocation
The problem of minimizing the transfer time between periodic orbits in the Earth-Moon elliptic restricted three-body problem using a multi-mode propulsion system is considered. By employing the true anomaly on the primary orbit as the independent variable and introducing normalized time as an additional state, the need to repeatedly solve Kepler's equation at arbitrary epochs is eliminated. Furthermore, a propellant constraint is imposed on the high-thrust mode to activate the multi-mode capabi…

Beyond the Training Data: Confidence-Guided Mixing of Parameterizations in a Hybrid AI-Climate Model
Persistent systematic errors in Earth system models (ESMs) arise from difficulties in representing the full diversity of subgrid, multiscale atmospheric convection and turbulence. Machine learning (ML) parameterizations trained on short high-resolution simulations show strong potential to reduce these errors. However, stable long-term atmospheric simulations with hybrid (physics + ML) ESMs remain difficult, as neural networks (NNs) trained offline often destabilize online runs. Training convect…

In this study, we use the example of the Atlantic Meridional Overturning Circulation (AMOC) to demonstrate the challenges associated with anticipating such transitions when the system is susceptible to bifurcation-induced, rate-induced, and noise-induced tipping. Using a calibrated AMOC box model, we conduct large ensemble sim…

European "socialism" is a compromise wherein the population gets services and, in exchange, the rich are allowed to continue to exist. This compromise developed to save capitalism from the threat of the working class just rising up and just doing it all themselves. Revolutions, it turns out, can be dangerous and may be subverted. It's generally safer, so Europe's working class decided, to accept some exploitation in exchange for not taking that chance.
The the strategy of "point guns at everyone until they comply" was a sustainable strategy, all of Europe would still be absolute monarchies, feudalism would still be the dominant economic system globally, and England would still control most of the land on Earth. Recognizing that this *isn't* the state of the world should give some clues as to how well Yarvin's ideas continue will play out in the real world.

@… just saw your story seeds site which is very cool. One gentle nudge: the "humanity learns how to sustainably live on Earth," framing erases all the groups of humans who do already know how to live sustainably, and have been doing do for tens of thousands of years. It's not "humans" who have "learning" to do, but specific groups of humans who have decisions to make.
Admittedly there's some learning to do about sustainably at scale, and about integrating good modern inventions with sustainable traditions, but I think that framing the problem as "we need to deploy existing rich knowledges of how to live sustainably" helps newcomers catch on to the decolonial thread of solarpunk more easily.

In the sixteenth century, lunacy was a constant theme that was never questioned. It was still frequent in the seventeenth century, but started to disappear, and by 1707, the year in which Le François asked the question ‘Estne aliquod lunae in corpora humana imperium?’ (Does the moon have any influence over the human body?), after lengthy discussions, the university decided that their reply was in the negative. In the course of the eighteenth century the moon was rarely cited among the causes of madness, even as a possible factor or an aggravation. But right at the end of the century the idea reappears, perhaps under the influence of English medicine, which had never entirely forgotten the moon, and Daquin, followed by Leuret and Guislain, all admitted the influence of the moon on the phases of maniacal excitement, or at the least on the agitation of their patients. But what is important here is not so much the return of the theme as the possibility and conditions necessary for its reappearance. It reappears entirely transformed, filled with a new significance that it did not formerly possess. In its traditional form, it designated an immediate influence, a direct coincidence in time and intersection in space, whose mode of action was entirely situated in the power of the stars. But in Daquin by contrast, the influence of the moon acts through a whole series of mediations, in a kind of hierarchy, surrounding man. The moon acts on the atmosphere with such intensity that it can set in motion a mass as heavy as the ocean. The nervous system, of all the parts that make up the human organism, is the part most sensitive to atmospheric variations, as the slightest variation in temperature, humidity or dryness can have serious effects upon it. The moon therefore, given the important power that its trajectory exerts on the atmosphere, is likely to act most on people whose nervous fibres are particularly delicate:
“Madness is an exclusively nervous condition, and the brain of a madman must therefore be infinitely more susceptible to the influence of the atmosphere, which itself undergoes considerable changes of intensity as a result of the different positions of the moon relative to the earth.” [Daquin, Philosophie de la folie, Paris, 1792]

Seasonal forecasting using the GenCast probabilistic machine learning model
Machine-learnt weather prediction (MLWP) models are now well established as being competitive with conventional numerical weather prediction (NWP) models in the medium range. However, there is still much uncertainty as to how this performance extends to longer timescales, where interactions with slower components of the earth system become important. We take GenCast, a state-of-the-art probabilistic MLWP model, and apply it to the task of seasonal forecasting with prescribed sea surface tempera…

RiverScope: High-Resolution River Masking Dataset
Surface water dynamics play a critical role in Earth's climate system, influencing ecosystems, agriculture, disaster resilience, and sustainable development. Yet monitoring rivers and surface water at fine spatial and temporal scales remains challenging -- especially for narrow or sediment-rich rivers that are poorly captured by low-resolution satellite data. To address this, we introduce RiverScope, a high-resolution dataset developed through collaboration between computer science and hydrolog…

Cavity Enhanced Emission from Telecom Rare-Earth System in Colloidal Host
Erbium incorporated in a ceria (CeO2) host offers strong potential as a spin qubit platform, providing a pathway toward telecom-compatible quantum memory. But erbium is a dim emitter due to its long excited state lifetime. Methods to enhance its emission rate and efficiency through nanophotonic cavity integration are therefore essential. In this work, we demonstrate cavity-enhanced emission from erbium doped CeO2. We couple colloidally synthesized erbium doped CeO2 nanocrystals to a silicon nan…

Modeling high and low extremes with a novel dynamic spatio-temporal model
Extreme environmental events such as severe storms, drought, heat waves, flash floods, and abrupt species collapse have become more prevalent in the earth-atmosphere dynamic system in recent years. In order to fully understand the underlying mechanisms and enhance informed decision-making, a flexible model capable of accommodating extremes is necessary. Existing dynamic spatio-temporal statistical models exhibit limitations in capturing extremes when assuming Gaussian error distributions, where…

Solar Hegemony: M-Dwarfs Are Unlikely to Host Observers Such as Ourselves
With no firm evidence for life beyond our solar system, inferences about the population observers such as ourselves rests upon the Earth as a single input, at least for now. Whilst the narrative of our home as a 'humdrum' system has become ingrained in the public psyche via Sagan, there are at least two striking facts about our existence which we know are certainly unusual. First, the stelliferous period spans ~10Tyr - yet here we are living in the first 0.1% of that volume. Second, over three-…

First principles study of [111]-oriented epitaxially strained Rare-Earth Nickelate NdNiO$_3$
Density functional theory is used to investigate the effect of biaxial strain on the structural, electronic and magnetic properties of [111]-oriented NdNiO$_3$, as a representative of the rare-earth perovskites that undergo metal-to-insulator transitions. We find that this constraint on the system induces unique structural phase transitions not previously observed under the well-studied bulk or [001]-oriented strained systems. We also report unique electronic behaviour, including amplification …

Optimal Solutions to Deflect Earth Crossing Objects Using Laser
This paper solves and analyzes a trajectory optimization problem to deflect Earth-crossing objects (ECOs) employing continuous thrust obtained using a laser ablative system. The optimal control is determined for various initial ECO-Earth configurations to achieve the desired miss distance. The formulation incorporates the gravitational effect on the object due to the Earth using the patched-conic method. The constrained trajectory optimization problem is solved using Non-Linear Programming (NLP…

Heh yes. Pretty much this.
"Much more will be written about proposals to build massive undersea walls to hold up Antarctic ice sheets, drill bore holes in Greenland to pump out lubricating meltwater, or scatter glass beads over glaciers. As informed and erudite I'm sure this will be, I don't think it will be as effective as simply yelling "What the hell do you think you are doing?!”"

Learning from nature: insights into GraphDOP's representations of the Earth System
Through a series of experiments, we provide evidence that the GraphDOP model - trained solely on meteorological observations, using no prior knowledge - develops internal representations of the Earth System state, structure and dynamics as well as the characteristics of different observing systems. Firstly, we demonstrate that the network constructs a unified latent representation of the Earth System state which is common across different observation types. For example, cloud structures maintai…

Can a convecting magma ocean offer a solution to the puzzling case of core convection in early earth?

Can a convecting magma ocean offer a solution to the puzzling case of core convection in early earth?
Convective flow in Earth's iron-rich liquid core drives self-sustained dynamo action, generating Earth's magnetic field, which is strongest among all terrestrial planets of the solar system. Rock records show that this magnetic field has been operative in Earth for at least 3.4 billion years (b.y). However, advanced high pressure experiments have revised the value of the thermal conductivity of the outer core, which implies an age for the inner core of less than 1 b.y., when compositional conve…

Two warm Earth-sized exoplanets and an Earth-sized candidate in the M5V-M6V binary system TOI-2267
We report two warm Earth-sized exoplanets orbiting the close binary TOI-2267 (M5+M6, separation ~8 au). Data from TESS and ground-based facilities confirm the planets, but we cannot determine which star they orbit. The planets have radii of 1.00+/-0.11 R_Earth (TOI-2267 b, P=2.28 d) and 1.14+/-0.13 R_Earth (TOI-2267 c, P=3.49 d) if around TOI-2267A, or 1.22+/-0.29 R_Earth and 1.36+/-0.33 R_Earth if around TOI-2267B. TESS also shows a candidate signal (TOI-2267.02, P=2.03 d, 0.95+/-0.12 or 1.13+…

The Impact of Enhanced EUV Flux on the Upper Atmosphere of Earth-like Exoplanets
Identifying Earth-like planets outside out solar system is a leading research goal in astronomy, but determining if candidate planets have atmospheres, and more importantly if they can retain atmospheres, is still out of reach. In this paper, we present our study on the impact of enhanced EUV flux on the stability and escape of the upper atmosphere of an Earth-like exoplanet using the Global Ionosphere and Thermosphere Model (GITM). We also investigate the differences between one- and three-dim…
