Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Expert consensus on safety and health risk assessment for suborbital space tourism (2026 edition)
The rapid development of suborbital commercial spaceflight has gradually transformed space tourism from a conceptual vision into tangible reality, presenting entirely new challenges for medical screening of ordinary passengers. Suborbital flight involves

Space and Time as A Priori Forms in the Works of Hermann Cohen and Ivan Lapshin
In the late nineteenth and early twentieth centuries the need to rethink the status of space and time which Kant considered to be a priori forms of sensibility was prompted by the emergence of new approaches to the methodology of scientific cognition. In

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

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.

Analyzing physical spaces as a means of understanding rhetoric
The following collaborative project is designed to encourage students to investigate how rhetoric functions in everyday locations. Specifically, this assignment prompts students to document, analyze, and present the physical design and makeup of ...

Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

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 ...

Test Spaces for Normal Spaces [PDF]
Let Q be a class of topological spaces. For X in Q, let dim X denote the dimension of X defined in terms of finite open coverings. If Q is the class of all normal spaces, then the dimension of spaces X in Q is characterized by the following theorem [2, p. 212]: dimX^n if, and only if, given any closed subset C of X, any continuous mapping of C into the
