The Role of Partisan Culture in Mental Health Language Online
The impact of culture on how people express distress in online support communities is increasingly a topic of interest within Computer Supported Cooperative Work (CSCW) and Human-Computer Interaction (HCI). In the United States, distinct cultures have emerged from each of the two dominant political parties, forming a primary lens by which people navigate online and offline worlds. We examine whether partisan culture may play a role in how U.S. Republican and Democrat users of online mental heal…

Record marine heat waves in 2023 covered 96% of oceans, lasted four times longer than average #ocean

Record marine heat waves in 2023 covered 96% of oceans, lasted four times longer than average
Heat waves aren't just getting worse on land, the majority of the world's oceans are experiencing record-breaking temperatures too. These marine heat waves are getting longer, more intense and reaching farther than ever before. In particular, 2023's marine heat waves (MHWs) exhibited the longest duration, widest extents, and highest intensities on record—and 2024 wasn't any better.

Regression approaches for modelling genotype-environment interaction and making predictions into unseen environments
In plant breeding and variety testing, there is an increasing interest in making use of environmental information to enhance predictions for new environments. Here, we will review linear mixed models that have been proposed for this purpose. The emphasis will be on predictions and on methods to assess the uncertainty of predictions for new environments. Our point of departure is straight-line regression, which may be extended to multiple environmental covariates and genotype-specific responses.…

Hackers disrupt communications of dozens of Iranian oil and cargo ships
A hacker group said it disabled communications on more than 60 Iranian oil tankers and cargo ships, severing links between the vessels, their ports, and the outside world in one of the largest cyberattacks on the country’s maritime sector.

Detectability of Covert Fissile Material Production in Nuclear Fusion Reactors via Antineutrino Emissions
Fusion power systems can in principle be used to make significant amounts of fissile material. To do so, an operator would have to introduce fertile material, such as uranium-238, in a suitable region of the reactor where it is exposed to an intense neutron flux. The possibility of using a fusion reactor for this purpose has raised the question of how these facilities can be monitored to ensure their peaceful use. This study examines whether covert production of fissile material in a declared f…

Machine learning-based multimodal prognostic models integrating pathology images and high-throughput omic data for overall survival prediction in cancer: a systematic review
Multimodal machine learning integrating histopathology and molecular data shows promise for cancer prognostication. We systematically reviewed studies combining whole slide images (WSIs) and high-throughput omics to predict overall survival. Searches of EMBASE, PubMed, and Cochrane CENTRAL (12/08/2024), plus citation screening, identified eligible studies. Data extraction used CHARMS; bias was assessed with PROBAST+AI; synthesis followed SWiM and PRISMA 2020. Protocol: PROSPERO (CRD42024594745)…

A judge ruled late Friday
the Trump administration cannot deny funding to Boston, Chicago, Denver, Los Angeles and 30 other cities and counties

U.S. District Judge William Orrick in San Francisco extended a preliminary injunction
blocking the administration from cutting off or conditioning the use of federal funds
for so-called “sanctuary” jurisdictions.

Judge blocks Trump from cutting funding over ‘sanctuary’ policies
A judge has ruled the Trump administration cannot deny funding to Boston, Chicago, Denver, Los Angeles and 30 other cities and counties because of policies that limit cooperation with federal immigration efforts. U.S. District Judge William Orrick on Friday extended a preliminary injunction blocking the administration from cutting off or conditioning the use of federal funds for so-called “sanctuary” jurisdictions. His earlier order protected more than a dozen other cities and counties, inc…

Multi-Agent Guided Policy Optimization
Due to practical constraints such as partial observability and limited communication, Centralized Training with Decentralized Execution (CTDE) has become the dominant paradigm in cooperative Multi-Agent Reinforcement Learning (MARL). However, existing CTDE methods often underutilize centralized training or lack theoretical guarantees. We propose Multi-Agent Guided Policy Optimization (MAGPO), a novel framework that better leverages centralized training by integrating centralized guidance with d…

Cooperative Suppression Strategy for Dual Thermal Transport Channels in Crystalline Materials
We propose a novel design principle for achieving ultralow thermal conductivity in crystalline materials via a "heavy-light and soft-stiff" structural motif. By combining heavy and light atomic species with soft and stiff bonding networks, both particle-like ($κ_p$) and wave-like ($κ_c$) phonon transport channels are concurrently suppressed. First-principles calculations show that this architecture induces a hierarchical phonon spectrum: soft-bonded heavy atoms generate dense low-frequency mo…
