How to Make a Four-Eyed Beetle

By Viviane Callier One of evolution’s oldest tricks is to apply old genetic building blocks at new times or places in development to create a new structure. But that isn’t the only way to innovate: A new study on dung beetles published this week in Proceedings of the National Academy of Sciences shows that eliminating […]

Odorant Receptor Gene in Codling Moth Also Affects Egg Production

A funny thing happened on the way to testing the CpomOR1 odorant receptor. Researchers at the USDA-Agricultural Research Service conducted an experiment on codling moth (Cydia pomonella) using the CRISPR/Cas9 gene-editing method to study the role played by a specific gene known as CpomOR1. The gene is highly expressed, or “switched on,” in the antennae […]

Bed Bug Genome Map May Provide Clues for Controlling Them

An international research team has successfully mapped the genome of the bed bug (Cimex lectularius) to get a better understanding of its genetic makeup. The findings — by researchers from 36 institutions — have been published in the journal Nature Communications. The genome is sort of like the bed bug’s blueprint. Now that the scientists […]
