The article investigates the effect of chemical compound on the lifespan of worms. Researchers from Washington University School of Medicine in St. Louis, Missouri have demonstrated that lifespans of roundworms can be extended even when the worms are well fed, they add that it only takes a chemical that blocks the worms' sense of smell. Researchers investigated the effect of ethosuximide in Caenorhabditis elegans and found out that it had the same life-extending effect as some well-studied genetic mutation in C. elegans. It notes that the mutations inhibit the activity of some neurons in the worm. Researchers conclude that exthosuximide also directly affected these neurons. It states that roundworms treated with ethosuximide lived longer up to 29% than normal.
