Niobium Phosphide: A New Ultrathin Conductor Outperforming Copper

Stanford researchers have discovered a novel 1.5-nanometer-thick niobium phosphide (NbP) film exhibiting superior conductivity to copper. Unlike traditional metals, whose resistance increases at the nanoscale, NbP's resistance decreases with decreasing thickness due to its surface being more conductive than its bulk. This 'topological semimetal' behavior promises energy-efficient integrated circuits. However, challenges remain for commercialization, including precise film thickness control.

Optimizing the Separating Axis Theorem with Gauss Map Traversal

Optimizing the Separating Axis Theorem with Gauss Map Traversal

This article presents an optimized collision detection algorithm for convex polyhedra. Reframing the Separating Axis Theorem (SAT) as a sphere-based optimization problem, the author reveals that the minimum lies at the intersections of great circles on a Gauss map. A graph traversal algorithm avoids repeated support function calculations, requiring only one full evaluation initially. The algorithm then efficiently updates the support point by traversing the Gauss map, resulting in significant performance gains. Tests show a 5-10x speedup over traditional SAT.

The DMZ: A River Remembered, A Nation Divided

Since 1953, the 250-kilometer DMZ has bisected the Korean Peninsula, a seemingly impenetrable scar on the land. However, a significant portion of this boundary lies across the Han River estuary, a 'neutral' zone according to the armistice agreement. The author recounts a family trip where the estuary's poignant history—a once-vibrant lifeline now choked by military presence—is revealed through their uncle's emotional response. The story contrasts the estuary's historical significance as a connector of people and communities with its current reality as a symbol of division and loss.

Kremlin-Backed Disinfo Bypasses Social Media Moderation via Malicious Ad Tech

2025-06-12

A new report exposes a sprawling ecosystem of malicious ad tech used not only by online scammers and hackers but also by Kremlin-backed disinformation campaigns to bypass social media moderation. The investigation focuses on the “Doppelganger” disinformation network, which uses sophisticated domain cloaking to spread pro-Russian narratives and infiltrate European media. This cloaking service shares infrastructure with VexTrio, arguably the oldest malicious traffic distribution system (TDS), and is linked to affiliate marketing services LosPollos and TacoLoco. These services employ deceptive tactics to trick users into enabling push notifications, which are then used to disseminate malware and scams. Researchers tied these services to Adspro Group, registered in the Czech Republic and Russia, with infrastructure in Switzerland. Despite Adspro's denial of ties to VexTrio, actions like LosPollos suspending its push monetization service and Adspro rebranding to Aimed Global suggest a connection to malicious activity. The report highlights the significant cybersecurity threat posed by this malicious ad tech ecosystem and advises users to be cautious about browser notification requests.

Beyond RAG: LLM Tool Calling Ushers in a New Era for Semantic Search

This article explores methods for implementing semantic search, particularly using LLMs for vector embedding search. While directly embedding user search terms and documents sometimes yields suboptimal results, new techniques like Nomic Embed Text v2 improve embedding methods, bringing questions and answers closer together in vector space. Furthermore, LLMs can synthesize potential answers, then use those embeddings to search for relevant documents. The article also introduces LLM-based Retrieval-Augmented Generation (RAG) systems, emphasizing that RAG doesn't rely on vector embeddings and can be combined with keyword search or hybrid search systems. The author argues that despite the emergence of long-context models, RAG won't disappear because the amount of data will always exceed model context capacity. The author favors the LLM tool-calling approach, exemplified by o3 and o4-mini, believing it's more effective than traditional RAG (single retrieval followed by direct answering).
