Es ist gut, dass wieder einmal eine rssische Desinformationskampagne und der hybriden Kriegsführung aufgedeckt und belegt wird.
Die Frage ist aber: Was folgt daraus? Was tun die Staaten, was die EU?
Die schlappen Reaktionen werden Darth #Putin nur weiter stimulieren. Es scheint zum Spiel in der russischen Führung geworden zu sein, auszuprobieren, wie man die EU ärgern und provozieren kann, oh…

A proud achievement of my half-century IT career happened in 1996 consulting to the #UNDP toward the first published edition of the Humanity Development Library.
It seemed easy enough: "It can be fairly estimated that 1/3, or about 20 million pages of UN, and as much University and NGO material are very useful. Those 20 million pages useful UN publications probably contain about 50% of solutions for major World problems. This information must be released in digital format for non-profit redistribution in all countries."
also portable and accessible to all platforms, everywhere.
Happily, not only did the project live on, but thanks to @… our once-intractable problem of global delivery is now globally solved!
So, whether or not this is timely, I don't know, but should you need to suddenly rebuild some semblance of civilization from scratch…

Around 56 million years ago,
Earth suddenly got much hotter.
Over about 5,000 years, the amount of carbon in the atmosphere drastically increased and global temperatures shot up by some 6°C.
As we show in new research published in Nature Communications,
one consequence was that many of the world’s plants could no longer thrive.
As a result, they soaked up less carbon from the atmosphere,
which may have contributed to another interesting thing about this pre…

56 million years ago, the Earth suddenly heated up – and many plants stopped working properly
It could be a sign of what’s to come.

From Neural Sensing to Stimulation: An Interdisciplinary Roadmap for Neurotechnology
Neurotechnologies are transforming how we measure, interpret, and modulate brain-body interactions, integrating real-time sensing, computation, and stimulation to enable precise physiological control. They hold transformative potential across clinical and non-clinical domains, from treating disorders to enhancing cognition and performance. Realizing this potential requires navigating complex, interdisciplinary challenges spanning neuroscience, materials science, device engineering, signal proce…

BrainForm: a Serious Game for BCI Training and Data Collection
$\textit{BrainForm}$ is a gamified Brain-Computer Interface (BCI) training system designed for scalable data collection using consumer hardware and a minimal setup. We investigated (1) how users develop BCI control skills across repeated sessions and (2) perceptual and performance effects of two visual stimulation textures. Game Experience Questionnaire (GEQ) scores for Flow}, Positive Affect, Competence and Challenge were strongly positive, indicating sustained engagement. A within-subject stu…

Modelling of magnetic vortex microdisc dynamics under varying magnetic field in biological viscoelastic environments
Magnetically driven microparticles provide a versatile platform for probing and manipulating biological systems, yet the physical framework governing their actuation in complex environments remains only partially explored. Within the field of cellular magneto-mechanical stimulation, vortex microdiscs have emerged as particularly promising candidates for developing novel therapeutic approaches. Here, we introduce a simplified two-dimensional model describing the magneto-mechanical response of su…

Abstract: Foundation models have shown remarkable success in fitting biological visual systems; however, their black-box nature inherently limits their utility for under- standing brain function. Here, we peek inside a SOTA foundation model of neural activity (Wang et al., 2025) as a physiologist might, characterizing each 'neuron' based on its temporal response properties to parametric stimuli. We analyze how different stimuli are represented in neural activity space by building decoding man- ifolds, and we analyze how different neurons are represented in stimulus-response space by building neural encoding manifolds. We find that the different processing stages of the model (i.e., the feedforward encoder, recurrent, and readout modules) each exhibit qualitatively different representational structures in these manifolds. The recurrent module shows a jump in capabilities over the encoder module by 'pushing apart' the representations of different temporal stimulus patterns; while the readout module achieves biological fidelity by using numerous specialized feature maps rather than biologically plausible mechanisms. Overall, we present this work as a study of the inner workings of a prominent neural foundation model, gaining insights into the biological relevance of its internals through the novel analysis of its neurons' joint temporal response patterns.

The Graded Betti Numbers of the Skeletons of Simplicial Complexes
In this paper, we study a class $C$ of squarefree monomial ideals $I$ in a polynomial ring $R=K[x_1,\dots,x_n]$ over a filed $K$ where $\dim R/I$ equals the maximum degree of the minimal generators of $I$ minus one. We show that the Stanley-Reisner ideal of any $i$-skeleton of a simplicial complex $Δ$ in the class $C$ for $-1\le i<\dimΔ$. Then, we introduce the notion of a degree resolution and prove that every ideal in the class $C$ possesses this property. Finally, we provides a formula to …

In August, a guest on Tucker Carlson’s podcast said something that immediately caught his interest.
The United States faces a fundamental rift
“between heritage Americans and the new political class,” Auron MacIntyre, a columnist for Blaze Media, argued.
“Heritage Americans
—what are those?” Carlson asked.
“You could find their last names in the Civil War registry,” MacIntyre explained.
This ancestry matters, he said, because America is not “a collection o…
