A transcriptional biosensor reveals mechanisms of α-ketoglutarate signaling to chromatin - Science | AAAS

A lung affected by deadly forms of COVID-19 not only loses essential cells for breathing but also undergoes profound changes in its internal organization and the way its cells communicate with each other. A study involving the Sant Pau Research Institute (IR Sant Pau), published in Nature Communications, has created a spatial map of this transformation and identified some of the molecular mechanisms that accompany the progression of lung damage and fibrosis.

ScienceNew research is showing what makes honeybee stings an effective, self-driving weapon. High speed cameras reveal how the stinger uses a double-piston that pumps up and down to drive it deeper while delivering its poison. New research slows down and shines light on a fatal defense mechanismAnand Ram · CBC News · Posted: Oct 12, 2026 3:00 PM EDT | Last Updated: October 12Listen to this articleEstimated 5 minutesThe audio version of this article is generated by AI-based technology.

High speed videography of an experiment captures how a western honey bee's stinger embeds itself deeper. (Ramirez Esquivel et al. 2026)The stinger of a western honey bee (Apis mellifera) is a weapon of last resort, designed to embed itself and deposit venom in flesh — most often resulting in the worker bee's death. New research published in the Proceedings of the National Academy of Sciences is quite literally shedding light on what makes this defence mechanism so effective.
