More than 14 million Americans have an irregular heartbeat that predisposes them to sudden death. New research by a biomedical engineer at Washington University in St. Louis seeks to understand the issue at the molecular level with the goal of improving therapies.
New research shows that an ancient protein that protects bacteria from bursting also helps pollen survive the dangerous transition from desiccated to hydrated once it lands on the female flower. But in pollen’s case, the protein has evolved to provide just the right amount of internal pressure: enough to power cell growth but not so much that the pollen bursts and dies.
In cells lining the airway, high levels of certain proteins have long been linked with the overproduction of mucus characteristic of diseases like asthma and COPD. New research from the School of Medicine provides clues to potentially counteract inappropriate mucus production.
