How the global fish trade is spreading 'forever chemicals' around the world
Eating fish may well be good for you, but it carries a hidden risk of exposure to so-called "forever chemicals." A new study published in the journal Science has revealed that the global seafood trade is acting as a massive delivery system for per- and polyfluoroalkyl substances (PFAS), industrial pollutants that persist in the environment for decades.

Donald Trump abruptly, and very imprecisely announced in a social media post,
“Because of other countries testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis.”
The suggestion that the United States might break with a more than three decade-long moratorium on explosive tests sparked a global wave of uncertainty, anxiety, and speculation about the impacts of a potential return to explosive nuclear testing.

Geopolitics, Geoeconomics and Risk:A Machine Learning Approach
We introduce a novel high-frequency daily panel dataset of both markets and news-based indicators -- including Geopolitical Risk, Economic Policy Uncertainty, Trade Policy Uncertainty, and Political Sentiment -- for 42 countries across both emerging and developed markets. Using this dataset, we study how sentiment dynamics shape sovereign risk, measured by Credit Default Swap (CDS) spreads, and evaluate their forecasting value relative to traditional drivers such as global monetary policy and m…

Performance Analysis of Machine Learning Algorithms in Chronic Kidney Disease Prediction
Kidneys are the filter of the human body. About 10% of the global population is thought to be affected by Chronic Kidney Disease (CKD), which causes kidney function to decline. To protect in danger patients from additional kidney damage, effective risk evaluation of CKD and appropriate CKD monitoring are crucial. Due to quick and precise detection capabilities, Machine Learning models can help practitioners accomplish this goal efficiently; therefore, an enormous number of diagnosis systems and…

A Risk Mitigation Model of Monetary Ecosystem with Stablecoins
Stablecoins have emerged as a significant component of global financial infrastructure, with aggregate market capitalization surpassing USD250 billion in 2025. Their increasing integration into payment and settlement systems has simultaneously introduced novel channels of systemic exposure, particularly liquidity risk during periods of market stress. This study develops a hybrid monetary architecture that embeds fiat-backed stablecoins within a central bank-anchored framework to structurally mi…

Attributing excess conflict risk in Syria to anthropogenic climate change

Attributing excess conflict risk in Syria to anthropogenic climate change
Some analyses suggest that drought in Syria during 2007-10 may have contributed to the 2011 onset of its civil war and that anthropogenic climate change had a detectable impact on the severity of that drought. Yet these qualitative statements alone do not allow us to estimate {how much} anthropogenic climate change amplified the risk of civil war in Syria. Climate policy is increasingly relying on global-scale cost-benefit analyses to inform major decisions, and any excess conflict risk imposed…

WASHINGTON, Nov. 18 – The National Press Club is deeply troubled by President Trump’s comments today regarding the killing of journalist Jamal Khashoggi. Mr. Khashoggi’s murder inside a diplomatic facility was a grave violation of human rights and a direct attack on press freedom. That fact is not in dispute.

Bigger is Faster in the Adaptive Immune Response
Zoonotic pathogens represent a growing global risk, yet the speed of adaptive immune activation across mammalian species remains poorly understood. Despite orders-of-magnitude differences in size and metabolic rate, we show that the time to initiate adaptive immunity is remarkably consistent across species. To understand this invariance, we analyse empirical data showing how the numbers and sizes of lymph nodes scale with body mass, finding that larger animals have both more and larger lymph no…

S-D-RSM: Stochastic Distributed Regularized Splitting Method for Large-Scale Convex Optimization Problems

Abstract: This paper investigates the problems large-scale distributed composite convex optimization, with motivations from a broad range of applications, including multi-agent systems, federated learning, smart grids, wireless sensor networks, compressed sensing, and so on. Stochastic gradient descent (SGD) and its variants are commonly employed to solve such problems. However, existing algorithms often rely on vanishing step sizes, strong convexity assumptions, or entail substantial computational overhead to ensure convergence or obtain favorable complexity. To bridge the gap between theory and practice, we integrate consensus optimization and operator splitting techniques (see Problem Reformulation) to develop a novel stochastic splitting algorithm, termed the \emph{stochastic distributed regularized splitting method} (S-D-RSM). In practice, S-D-RSM performs parallel updates of proximal mappings and gradient information for only a randomly selected subset of agents at each iteration. By introducing regularization terms, it effectively mitigates consensus discrepancies among distributed nodes. In contrast to conventional stochastic methods, our theoretical analysis establishes that S-D-RSM achieves global convergence without requiring diminishing step sizes or strong convexity assumptions. Furthermore, it achieves an iteration complexity of $\mathcal{O}(1/\epsilon)$ with respect to both the objective function value and the consensus error. Numerical experiments show that S-D-RSM achieves up to 2--3$\times$ speedup compared to state-of-the-art baselines, while maintaining comparable or better accuracy. These results not only validate the algorithm's theoretical guarantees but also demonstrate its effectiveness in practical tasks such as compressed sensing and empirical risk minimization.

Who gets hit first and who recovers last? Evidence from Indian Coastal Flood Shock
Catastrophic floods directly risk 1.8 billion lives worldwide, most of whom are from East and South Asia. How do extreme floods reshape paid labor outcomes? To answer this, I focus on a 1-in-100 year flood event in India. I first combine Sentinel-1 SAR with JRC Global Surface Water dataset to generate flood map. Using information from this map in various rounds of periodic labor force surveys, I estimate gender-specific dynamic effects of the flood shock. Key results show that men experienced s…
