Officials at Barksdale Air Force Base in Louisiana revealed that an'unmanned aerial system' - better known as a remote-controlled drone - was spotted near the facility Monday morning. Since drones are strictly prohibited from flying near or over the base, the Air Force temporarily raised their Force Protection Condition (FPCON) level to'Charlie,' meaning a possible terrorist threat had been detected . Barksdale Air Force Base is home to the military's fleet of B-52 bombers, capable of delivering nuclear strikes around the world. Base officials noted that Monday's incident was still under investigation, and no details on where the mystery drone came from or if it was captured have emerged.


Low-degree Lower bounds for clustering in moderate dimension

Carpentier, Alexandra, Verzelen, Nicolas

We study the fundamental problem of clustering $n$ points into $K$ groups drawn from a mixture of isotropic Gaussians in $\mathbb{R}^d$. Specifically, we investigate the requisite minimal distance $Δ$ between mean vectors to partially recover the underlying partition. While the minimax-optimal threshold for $Δ$ is well-established, a significant gap exists between this information-theoretic limit and the performance of known polynomial-time procedures. Although this gap was recently characterized in the high-dimensional regime ($n \leq dK$), it remains largely unexplored in the moderate-dimensional regime ($n \geq dK$). In this manuscript, we address this regime by establishing a new low-degree polynomial lower bound for the moderate-dimensional case when $d \geq K$. We show that while the difficulty of clustering for $n \leq dK$ is primarily driven by dimension reduction and spectral methods, the moderate-dimensional regime involves more delicate phenomena leading to a "non-parametric rate". We provide a novel non-spectral algorithm matching this rate, shedding new light on the computational limits of the clustering problem in moderate dimension.


Don't make us security guards, says teacher stabbed by pupil

Don't make us security guards, says teacher stabbed by pupil A teacher who thought she was going to die when she was stabbed by a 13-year-old pupil in the schoolyard has said giving staff handheld scanners will not stop violence in schools. Liz Hopkin, who was attacked at Ysgol Dyffryn Aman in 2024, said she felt really worried after the Welsh government announced it would offer school staff more guidance on what to do if they suspected a pupil had brought a weapon into school. It comes as a 15-year-old boy was charged with attempted murder after a teacher was stabbed at a school in the neighbouring county. Hopkin said teachers aren't security, while the Welsh government said the resources were about prevention, building on existing guidance. Hopkin, her colleague Fiona Elias and a pupil were attacked at the school where she worked in Ammanford, Carmarthenshire, by a girl who had previously been found with a knife.



The El Paso No-Fly Debacle Is Just the Beginning of a Drone Defense Mess

WIRED

Fears over a drug cartel drone over Texas sparked a recent airspace shutdown in El Paso and New Mexico, highlighting just how tricky it can be to deploy anti-drone weapons near cities. A shocking but ultimately brief airspace closure over El Paso, Texas, and parts of New Mexico last week is stoking unease among pilots and the broader public about the status of United States anti-drone defenses. As low-cost UAV equipment proliferates around the world, analysts have repeatedly warned that destructive attacks perpetrated using drones are inevitable . It is challenging to develop nimble and safe countermeasures, though, given that things like jamming or attempting to shoot down a drone are difficult--or even impossible--to carry out safely in populated areas, much less densely populated cities. In the case of the El Paso incident, the Federal Aviation Administration originally set the airspace closure to last 10 days, but ultimately lifted it after eight hours.




US opens probe after a Waymo self-driving car hit a child near a school

Al Jazeera

The United States National Highway Traffic Safety Administration (NHTSA) said it is opening an investigation after a Waymo self-driving vehicle struck a child near an elementary school in Santa Monica, California, last week, causing minor injuries and renewing concerns about the safety of robotaxis. The car safety agency said on Thursday that the child ran across the street on January 23 from behind a double-parked SUV towards the school and was struck by the Alphabet-unit Waymo autonomous vehicle during normal school drop-off hours. The agency said there were other children, a crossing guard, and several double-parked vehicles in the vicinity. The US Senate Commerce Committee had already scheduled a hearing on self-driving cars for February 4, which will include Waymo Chief Safety Officer Mauricio Pena. The National Transportation Safety Board (NTSB) also said it will investigate the incident.


What the Numbers Show About AI's Harms

Booth is a reporter at TIME. Booth is a reporter at TIME. With the widespread adoption of artificial intelligence around the world over the past year, the technology's potential to cause harm has become clearer. Reports of AI-related incidents rose 50% year-over-year from 2022 to 2024, and in the 10 months to October 2025, incidents had already surpassed the 2024 total, according to the AI Incident Database, a crowd-sourced repository of media reports on AI mishaps. Incidents arising from use of the technology, such as deepfake-enabled scams and chatbot-induced delusions have been rising steadily, according to the latest data.
