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.
Researchers have determined that the irritating screech produced when peeling Scotch tape results from shock waves generated by micro-cracks traveling at supersonic speeds. The findings, detailed in a new study, explain a phenomenon long observed but not fully understood. The research builds on decades of scientific interest in the tape's unusual properties.

Researchers in South Korea have successfully reproduced a rare golden fabric known as sea silk, lost for over 2,000 years. Using threads from a farmed clam, the team not only revived the material but also explained its enduring shimmer. This breakthrough promises sustainable alternatives to traditional textiles.
