"A Buzz in the World of Chemistry" is a frequent IELTS Reading passage that explores the fascinating intersection of entomology and pharmaceutical science. It details how scientists study insects—specifically their chemical defenses—to discover new medicines.
: Insects make up the majority of animal life on Earth. To survive millions of years against bacteria, fungi, and predators, they developed potent chemical cocktails.
: The test rarely uses the exact words from the question. For example, the keyword branch in the text maps to offshoot in the answer file. "" is a popular IELTS Academic Reading passage

The sensitivity of compound analytical techniques has developed apace with the technology, and whereas, in the 1980s, one required several millimoles of product to characterise, now this can be done with femtomoles or, in some cases, attomoles (10⁻¹⁸ moles)! Therefore, one need only recover product from 1 bead, about 2‑3 picomoles. Automated systems are now being developed to synthesise on single magnetic beads using only 2‑3 nanolitres of reagent per cycle. When the ‘classical’ Tea‑bag strategy was developed, 100 millilitres per cycle were considered to be a phenomenal solvent cost‑cutting exercise.
A branch or derivative of a primary field (synthetic organic chemistry). In vogue: Popular or fashionable; a buzzword. Limitless: The potential number of combinations (
