NATO and the drones. This weekend, drones were flying spy missions over a Belgian Air Force base. Said the country's Defense Minister: "A helicopter and police vehicles chased the drone, but lost it after several kilometers.”

Drones spotted above Belgian airbase were ‘spying’ on military planes, defense minister says
Several drones spotted above a Belgian airbase over the weekend were there “to spy” on military fighter jets, the country’s defense minister said Sunday, at a time when European nations are on high alert for airspace intrusions.

ReeMark: Reeb Graphs for Simulating Patterns of Life in Spatiotemporal Trajectories
Accurately modeling human mobility is critical for urban planning, epidemiology, and traffic management. In this work, we introduce Markovian Reeb Graphs, a novel framework for simulating spatiotemporal trajectories that preserve Patterns of Life (PoLs) learned from baseline data. By combining individual- and population-level mobility structures within a probabilistic topological model, our approach generates realistic future trajectories that capture both consistency and variability in daily l…

Rafael Viñoly will forever be remembered as the guy who designed two buildings, one in Las Vegas and the other in London, that use a special shape that turns sunlight into a death ray. When confronted about this by The Guardian, he gave the best interview possible:
“I knew this was going to happen [...] When it was spotted on a second design iteration, we judged the temperature was going to be about 36 degrees, but it's turned out to be more like 72 degrees. They are callin…

Federated Spatiotemporal Graph Learning for Passive Attack Detection in Smart Grids
Smart grids are exposed to passive eavesdropping, where attackers listen silently to communication links. Although no data is actively altered, such reconnaissance can reveal grid topology, consumption patterns, and operational behavior, creating a gateway to more severe targeted attacks. Detecting this threat is difficult because the signals it produces are faint, short-lived, and often disappear when traffic is examined by a single node or along a single timeline. This paper introduces a grap…

The world continues to dawdle politically in its response to the climate crisis
but clean energy is booming,
-- responsible for almost all new energy capacity and drawing double the investment of fossil fuels globally. The market has shifted.
Most starkly, though, Trump has become the planet’s foremost advocate of fossil fuels,
throwing the might of the US presidency into a rearguard battle to keep the world mired in the era of combusted carbon.
There is now no …

Latent Diffusion Unlearning: Protecting Against Unauthorized Personalization Through Trajectory Shifted Perturbations
Text-to-image diffusion models have demonstrated remarkable effectiveness in rapid and high-fidelity personalization, even when provided with only a few user images. However, the effectiveness of personalization techniques has lead to concerns regarding data privacy, intellectual property protection, and unauthorized usage. To mitigate such unauthorized usage and model replication, the idea of generating ``unlearnable'' training samples utilizing image poisoning techniques has emerged. Existing…
