Good Morning #Canada
Today, while doing my morning Google thingy, I learned that Elon Musk has Canadian Citizenship. Now I need a shower.
Canada is pretty picky when we look for individuals who should be Canadian. Only 6 non-citizens have ever been recognized as Honorary Canadians, which takes an Act of Parliament to be designated with the honour. It provides zero rights or privileges but looks good on your resume. It is far more likely that non-citizens could be awarded the Order of Canada as they are eligible if they have made a significant contribution to Canadian society or had a positive impact on the world at large. As of August 2025, 8,647 people have been appointed to the order, an average of 150 per year since the honour was established in 1967. There is no list of non-Canadian recipients, as the government doesn't track them separately, but Queen Elizabeth II was awarded her Sovereign badge in 1970.

Moisture-driven CO2 direct air capture and delivery for cultivating cyanobacteria
A moisture-driven air capture system was developed and demonstrated for cultivating cyanobacteria and microalgae at the flask (50 mL), bench (12 L) and small pilot (840 L) scale. Purolite A501 anion exchange resin beads were found to be biocompatible and rapidly deliver air-captured CO2 when immersed directly in an alkaline cultivation medium containing cyanobacteria or microalgae. Flask-scale cultivation trials showed A501 could sustain rapid growth (190 mg/L/d) of the cyanobacterium Synechocy…

trAIce3D: A Prompt-Driven Transformer Based U-Net for Semantic Segmentation of Microglial Cells from Large-Scale 3D Microscopy Images
The shape of a cell contains essential information about its function within the biological system. Segmenting these structures from large-scale 3D microscopy images is challenging, limiting clinical insights especially for microglia, immune-associated cells involved in neurodegenerative diseases. Existing segmentation methods mainly focus on cell bodies, struggle with overlapping structures, perform poorly on noisy images, require hyperparameter tuning for each new dataset, or rely on tedious …

This is rather nice. #sound

Tony Regan #FTRS372
Sunshine, bassline and, erm, batty whine. Yes, its Famz Tree's favourite weekend of the year, when all the best bits of our community cram together in London W10, filling our body and soul with chicken, rum and the loudest, sweetest, life affirming music that we all live for. The fact that, in doing so, we manage to wind up the assorted Mail journos, Tory councillors, online rage baiters and pricks like Farage only adds to the fun. Big up all those who made it down there. Here's to years more t…

Stochastic diffusive energy balance climate model with a multiplicative noise modeling the Solar variability
We prove the existence, uniqueness, and comparison of solutions for a nonlinear stochastic parabolic partial differential equation that includes the Solar variability in terms of a multiplicative Wiener cylindrical noise in the term of the absorbed radiative energy in a simplified diffusive one-dimensional Energy Balance Model. We introduce a hybrid co-albedo nonlinear term, which has the advantages of both the Sellers model, as it is a continuous function, and the Budyko model, as it has an in…

Dynamic Interfacial Quantum Dipoles in Charge Transfer Heterostructures
Hysteretic gate responses of two-dimensional material heterostructures serve as sensitive probes of the underlying electronic states and hold significant promise for the development of novel nanoelectronic devices. Here we identify a new mechanism of hysteretic behavior in graphene/$h$BN/$α$-$\mathrm{RuCl_3}$ charge transfer field effect devices. The hysteresis loop exhibits a sharp onset under low temperatures and evolves symmetrically relative to the charge transfer equilibrium. Unlike conve…

Design and demonstration of a direct air capture system with moisture-driven CO2 delivery into aqueous medium
A moisture-driven air capture (DAC) system was designed and demonstrated. A laboratory-scale system delivering ~1 g CO2 per day was demonstrated in a laminar flow hood and a small pilot-scale system that could deliver ~100 g CO2 daily was operated outdoors in a 4.2 m2 (areal surface area) raceway pond. Elongated mesh tube packets were designed to contain AER beads with high surface area for contacting the air and were found to reduce drying and CO2 loading time ~4-fold over larger mesh bags. Wh…

Memory-aware feedback enhances power in active information engines
We study an information engine operating in an active bath, where a Brownian particle confined in a harmonic trap undergoes feedback-driven displacement cycles. Unlike thermal environments, active baths exhibit temporally correlated fluctuations, introducing memory effects that challenge conventional feedback strategies. Extending the framework of stochastic thermodynamics to account for such memory, we analyze a feedback protocol that periodically shifts the potential minimum based on noisy me…
