Prince George Search and Rescue (PGSAR) have safely located a man in his late 70s who became lost while hiking the Great Divide Trail. PGSAR says the …

Spotted this tiny praying mantis peeping in our window. I think just under 2 centimeters long. I tried to get my index finger in for scale.

Milli-Tesla Quantization enabled by Tuneable Coulomb Screening in Large-Angle Twisted Graphene
The electronic quality of graphene has improved significantly over the past two decades, revealing novel phenomena. However, even state-of-the-art devices exhibit substantial spatial charge fluctuations originating from charged defects inside the encapsulating crystals, limiting their performance. Here, we overcome this issue by assembling devices in which graphene is encapsulated by other graphene layers while remaining electronically decoupled from them via a large twist angle (~10-30°). Dop…

A test of seven AI chatbots' abilities to identify news photos' location, date, and photographer showed all failed to consistently identify photos' provenance (Columbia Journalism Review)

Why AI models are bad at verifying photos
Many of the latest large language models, including OpenAI’s recently released GPT-5, tout an impressive capability: reasoning about images. We have seen viral trends of AI models geolocating obscure vacation pictures, impressive demos of LLMs correctly analyzing blurry or cropped photos, and promising results on benchmark tests. These seem to be fueling punditry on whether […]

Technologies that promise to track, manage, and supervise workers,
increasingly using artificial intelligence,
are entrenched in the developing world, according to a new report by Coworker.org,
a labor rights nonprofit based in New York. 
Audits of more than 150 startups and regional companies based in Kenya, Nigeria, Colombia, Brazil, Mexico, and India showed
workplace surveillance is expanding in scale and sophistication, the researchers said.
While lar…

VC money is fueling a global boom in worker surveillance tech
A funding surge has given rise to technologies to track, analyze and manage workers — often in countries with little regulation.

Elliptical K-Nearest Neighbors -- Path Optimization via Coulomb's Law and Invalid Vertices in C-space Obstacles
Path planning has long been an important and active research area in robotics. To address challenges in high-dimensional motion planning, this study introduces the Force Direction Informed Trees (FDIT*), a sampling-based planner designed to enhance speed and cost-effectiveness in pathfinding. FDIT* builds upon the state-of-the-art informed sampling planner, the Effort Informed Trees (EIT*), by capitalizing on often-overlooked information in invalid vertices. It incorporates principles of physic…

Inducing ferromagnetism by structural engineering in a strongly spin-orbit coupled oxide
Magnetic materials with strong spin-orbit coupling (SOC) are essential for the advancement of spin-orbitronic devices, as they enable efficient spin-charge conversion, complex magnetic structures, spin-valley physics, topological phases and other exotic phenomena. 5d transition-metal oxides such as SrIrO3 feature large SOC, but usually show paramagnetic behavior due to broad bands and a low density of states at the Fermi level, accompanied by a relatively low Coulomb repulsion. Here, we unveil …

Coinductive well-foundedness
We introduce a coinductive version of the well-foundedness of N that is used in our proof within minimal logic of the constructive counterpart CLNP to the standard least number principle LNP. According to CLNP, an inhabited complemented subset of N has a least element if and only if it is downset located. The use of complemented subsets of N in the formulation of CLNP, instead of subsets of N, allows a positive approach to the subject that avoids negation. Generalising the coinductive well-foun…

Trump claimed that Joe Biden had “established toxic diversity, equity and inclusion ideology as a guiding principle of American AI development”.
“But the American people do not want woke Marxist lunacy in the AI models,” Trump said
Trump told assembled industry leaders that he wants them to “change the name” of artificial intelligence
and that they should not be forced to pay the authors of articles or books they use to train their large language models

Understanding high photocatalytic activity of the TiO2 high-pressure columbite phase by experiments and first-principles calculations
The clean production of hydrogen as a zero-emission fuel can be done using photocatalysis, with TiO2 being one of the most promising photocatalysts. However, the activity of TiO2 anatase and rutile phases is still limited. In this study, an oxygen-deficient high-pressure phase of TiO2, columbite, is stabilized by a high-pressure torsion method. The phase is utilized as an active photocatalyst for hydrogen production, and the mechanism of its high activity is examined using density functional th…
