Greetings TWiM crew!
What happens to us after we die? A decomposing corpse becomes its own mini-ecosystem, hosting insects, scavengers and multitudes of microbes. Microbes from the environment, the corpse, as well as the insects and scavengers are blended together and work to recycle tissues back to t... Read More
This episode: Feeding mice high-fiber diets reduces their risk of allergic airway disease, even across generations!

One of the first challenges is in properly diagnosing Zika infection. Diagnosis is challenging for several reasons: first, many infected individuals don’t suffer severe symptoms. Those that do have relatively non-specific symptoms of low-grade fever, headaches, and muscle soreness that are somet... Read More

The TWiPanosomes solve the case of the Young Man from Anchorage, and discuss how cestode parasites increase the resistance of brine shrimp to arsenic toxicity.
Michael returns to help the TWiP trio solve the case of the Delusional African Expatriate, who then discuss the association of natural and induced antibodies in mice with differential susceptibility to secondary cystic echinococcosis.
