Macromolecular Rapid Communications, EarlyView.Light‐programmable, non‐cytotoxic ion gels based on ABC triblock copolymers undergo photoreversible sol‐gel transitions, crossing the rheological boundary (tan δ ∼ 1). UV–vis light irradiation modulates the lifetime of reversible junctions, switching the scaffold between liquid‐like and solid (gel)‐like states.

Designing Chimeric LOV Photoswitches
Chemistry & Biology, 2012 The LOV domain from Avena sativa has a C-terminal (Jα) helix that dissociates and unfolds when the protein is exposed to blue light. Using computational protein design methods, Lungu et al., in this issue of Chemistry & Biology, created chimeric Jα sequences that show photo-controlled interactions with chosen targets.

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects
Insect Science, EarlyView.Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.
