What is the US critical minerals stockpile? Has the Trump administration overplayed its spin? United States aviation authorities have announced that the airspace over El Paso, Texas, has been reopened after initially closing the airspace due to an alleged drone incursion from a Mexican cartel. Wednesday's announcement walked back an earlier statement from the Federal Aviation Administration (FAA), abruptly pausing air traffic over the southern border city for 10 days. By late morning, though, the FAA announced that flights would resume in and out of the area as normal, prompting questions about the legitimacy of the drone claims. "The temporary closure of airspace over El Paso has been lifted.

We introduce a system for real-time sperm whale rendezvous at sea using an autonomous uncrewed aerial vehicle. Our system employs model-based reinforcement learning that combines in situ sensor data with an empirical whale dive model to guide navigation decisions. Key challenges include (i) real-time acoustic tracking in the presence of multiple whales, (ii) distributed communication and decision-making for robot deployments, and (iii) on-board signal processing and long-range detection from fish-trackers. We evaluate our system by conducting rendezvous with sperm whales at sea in Dominica, performing hardware experiments on land, and running simulations using whale trajectories interpolated from marine biologists' surface observations.

Is the fall of Pokrovsk inevitable? Is Trump losing patience with Putin? Will sanctions against Russian oil giants hurt Putin? Russia launched "massive" attacks on Ukraine's capital Kyiv, killing at least six people in the Desnianskyi district, the city's Mayor Vitali Klitschko wrote on Telegram. At least 35 people were also injured.

This Is the Nuclear-Powered Ship Deployed in Trump's War on Drug Boats The USS is a $13 billion aircraft carrier sailing to the Caribbean with nuclear propulsion, an electromagnetic plane launcher, and 90 aircraft onboard. The Pentagon has deployed the USS Gerald R. Ford in an anti-drug trafficking mission in the Caribbean. The USS, the US Navy's most advanced aircraft carrier, is heading to the Caribbean Sea as part of a Pentagon strategy it says is meant to strengthen the fight against drug trafficking in South America. The news was confirmed late last week by Sean Parnell, assistant secretary of defense for public affairs, through his social networks . In his message, he explained that the deployment of the "will strengthen the United States' ability to detect, monitor and dismantle illicit actors and activities that compromise the security and prosperity of US territory, as well as our stability in the Western Hemisphere."

China will soon have a new Five Year Plan. Here's how they have changed the world so far China's top leaders are gathering in Beijing this week to decide on the country's key goals and aspirations for the rest of the decade. Every year or so, the country's highest political body, the Central Committee of the Chinese Communist Party, convenes for a week of meetings, also known as a Plenum. What it decides at this one will eventually form the basis of China's next Five Year Plan - the blueprint that the world's second largest economy will follow between 2026 and 2030. The full plan won't come until next year, but officials are likely to hint at its contents on Wednesday and have previously given more details within a week of that.

Breakthroughs, discoveries, and DIY tips sent every weekday. The smelly, brown seaweed can put a damper on a day at the beach at best and hinder baby turtles on their way to the ocean at worst. Only about one in 1,000 sea turtle hatchlings survive to adulthood, and might be added to their already long list of challenges . The new findings detailed in a study published in the explores the role that this brown seaweed plays on vulnerable sea turtle populations. "For sea turtle hatchlings, reaching the ocean is already a race against time - and survival. Now, increasingly large mats of sargassum are adding new challenges to this critical journey," study co-author and Florida Atlantic University biologist Sarah Milton, said in a statement .

Abstract--Accurate real-time buoyancy modeling is essential for high-fidelity Autonomous Underwater V e-hicle (AUV) simulations, yet NVIDIA Isaac Sim lacks a native buoyancy system, requiring external solutions for precise underwater physics. This paper presents a novel convex hull-based approach to dynamically compute the submerged volume of an AUV in real time. By extracting mesh geometry from the simulation environment and calculating the hull portion intersecting the water level along the z-axis, our method enhances accuracy over traditional geometric approximations. A cross-sectional area extension reduces computational overhead, enabling efficient buoyant force updates that adapt to orientation, depth, and sinusoidal wave fluctuations ( 0.3 m). T ested on a custom AUV design for SAUVC 2025, this approach delivers real-time performance and scalability, improving simulation fidelity for underwater robotics research without precomputed hydrodynamic models.

Storm surge is one of the deadliest hazards posed by tropical cyclones (TCs), yet assessing its current and future risk is difficult due to the phenomenon's rarity and physical complexity. Recent advances in artificial intelligence applications to natural hazard modeling suggest a new avenue for addressing this problem. We utilize a deep learning storm surge model to efficiently estimate coastal surge risk in the United States from 900,000 synthetic TC events, accounting for projected changes in TC behavior and sea levels. The derived historical 100-year surge (the event with a 1% yearly exceedance probability) agrees well with historical observations and other modeling techniques. When coupled with an inundation model, we find that heightened TC intensities and sea levels by the end of the century result in a 50% increase in population at risk. Key findings include markedly heightened risk in Florida, and critical thresholds identified in Georgia and South Carolina.

Since 2011, rafts of floating \emph{Sargassum} seaweed have frequently obstructed the coasts of the Intra-Americas Seas. The motion of the rafts is represented by a high-dimensional nonlinear dynamical system. Referred to as the eBOMB model, this builds on the Maxey--Riley equation by incorporating interactions between clumps of \emph{Sargassum} forming a raft and the effects of Earth's rotation. The absence of a predictive law for the rafts' centers of mass suggests a need for machine learning. In this paper, we evaluate and contrast Long Short-Term Memory (LSTM) Recurrent Neural Networks (RNNs) and Sparse Identification of Nonlinear Dynamics (SINDy). In both cases, a physics-inspired closure modeling approach is taken rooted in eBOMB. Specifically, the LSTM model learns a mapping from a collection of eBOMB variables to the difference between raft center-of-mass and ocean velocities. The SINDy model's library of candidate functions is suggested by eBOMB variables and includes windowed velocity terms incorporating far-field effects of the carrying flow. Both LSTM and SINDy models perform most effectively in conditions with tightly bonded clumps, despite declining precision with rising complexity, such as with wind effects and when assessing loosely connected clumps. The LSTM model delivered the best results when designs were straightforward, with fewer neurons and hidden layers. While LSTM model serves as an opaque black-box model lacking interpretability, the SINDy model brings transparency by discerning explicit functional relationships through the function libraries. Integration of the windowed velocity terms enabled effective modeling of nonlocal interactions, particularly in datasets featuring sparsely connected rafts.
