Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Diversity and complexity in neural organoids
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Exclusion Problems and the Cardinality of Logical Space [PDF]
Wittgenstein’s atomist picture, as embodied in his Tractatus, is initially very appealing. However, it faces the famous colour-exclusion problem. In this paper, I shall explain when the atomist picture can be defended (in principle) in the face of that ...

Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

The Principle of Autonomy in Kant's Moral Theory: Its Rise and Fall [PDF]
In this essay, “The Principle of Autonomy in Kant’s Moral Theory: Its Rise and Fall,” Pauline Kleingeld notes that Kant’s Principle of Autonomy, which played a central role in both the Groundwork for the Metaphysics of Morals and the Critique of ...

Non-existence of a Hohenberg-Kohn Variational Principle in Total Current Density Functional Theory
For a many-electron system, whether the particle density $\rho(\mathbf{r})$ and the total current density $\mathbf{j}(\mathbf{r})$ are sufficient to determine the one-body potential $V(\mathbf{r})$ and vector potential $\mathbf{A}(\mathbf{r})$, is still ...

AAA+ protein unfoldases—the Moirai of the proteome
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

The law of becoming and the shackles of sufficient reason in Quentin Meillassoux [PDF]
Examining the concept of ‘hyper-chaos’ - a time beyond time, not of perpetual becoming, but of lawless creation and destruction, premised upon an abandonment of the principle of sufficient reason - as described in the work of French philosopher Quentin ...
