Outbreak of H7N2 Flu in Cats

Many mBiosphere readers will know that the influenza A virus infects multiple species, and this ability to infect birds, humans, and other mammals such as pigs is one of the ways virions can exchange genetic information, leading to new viruses able to cause major outbreaks. However, few mBiosphe... Read More

Peanuts and Probiotics

The world has a problem: an exploding human population, which will require crop yields to double by 2050 without increasing crop acreage. Solving this problem will necessitate help from some of the smallest members of Earth’s population using a concept that has both George Washington Carver and ... Read More

Bacterial protein structure could aid development of new antibiotics

Bacterial cells have an added layer of protection, called the cell wall, that animal cells don’t. Assembling this tough armor entails multiple steps, some of which are targeted by antibiotics like penicillin and vancomycin.

Yet one step in the process has remained a mystery because the molecu... Read More
