Elucidating the Stereodirecting Effect of C‐4 Acyl Groups on Galactosyl Donors

open access: yesAngewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Tipping the balance of the reaction coordinate by changing a single protecting group. We demonstrate that α‐ and β‐galactosyl triflates are formed during galactosylation reactions and likely glycosylate according to a Curtin–Hammett scenario. C‐4 acyl groups exert their stereodirecting effect by sterically blocking displacement of α‐galactosyl ...

Tissue‐specific recombination‐activated clonal and inducible transcription (TRAC‐IT) enables controlled gene activation in stably marked tissues

open access: yesThe Plant Journal, Volume 127, Issue 6, September 2026.
Significance Statement Tissue‐specific Recombination‐Activated Clonal and Inducible Transcription (TRAC‐IT), a two‐step system that uncouples inducible gene expression from cell identity. TRAC‐IT offers a versatile tool that provides new technical possibilities to explore the mechanisms driving plant development in a stable tissue‐specific fashion.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

open access: yesFish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

The spread of non‐native species

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

The basic resolvents of position and momentum operators form a total set in the resolvent algebra [PDF]

open access: yes, 2023
Let Q and P be the position and momentum operators of a particle in one dimension. It is shown that all compact operators can be approximated in norm by linear combinations of the basic resolvents $(aQ + bP - i r)^{-1}$ for real constants $a,b,r \ne 0$

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Directed self-assembly of a helical nanofilament liquid crystal phase for use as structural color reflectors [PDF]

open access: yes, 2019
The fabrication of molecular structures with a desired morphology, e.g., nanotubes, nanoribbons, nanosprings, and sponges, is essential for the advancement of nanotechnology. Unfortunately, realization of this objective is expensive and complicated. Here,
