A suite of recent studies in American Chemical Society journals describes two‑year‑old brain organoids with measurable activity, a wearable electrospinning glove for on‑site wound patches, an edible coating from the Brazilian “wolf apple” that kept baby carrots fresh for up to 15 days at room temperature, and microplastics detected in post‑mortem human retinas.
Scientists have identified a key reason gold resists tarnishing, potentially opening new uses for the metal in chemistry. Simulations show how atomic arrangements on gold surfaces prevent reactions with oxygen. The findings come from detailed quantum modeling at Tulane University.

Researchers at the University of South Florida have identified the mechanism that makes carbon black particles strengthen rubber, resolving a scientific puzzle that has lasted nearly a century. Their computer simulations reveal how the material resists stretching by effectively fighting against itself.
Chemists at Rice University have replicated Thomas Edison's 1879 light bulb experiments and found evidence that the inventor may have accidentally produced graphene as a byproduct. The discovery, detailed in a new paper, highlights how modern tools can reinterpret historical innovations. This turbostratic graphene emerged from heating carbon filaments to extreme temperatures.
