Why are obesity, juvenile diabetes and asthma increasing? Is it something in the environment or in our modern lifestyle? Dr. Martin Blaser thinks that it may be due to changes in our microbiome – the ecosystem of tiny microscopic creatures that live in and on us. Learn about his hypothesis th... Read More
In a healthy adult human body, most internal organs such as the brain, spleen, liver, and heart are devoid of microorganisms because the immune system keeps them in check. After human host death, however, the immune system falters and microorganisms proliferate throughout the body beginning in ... Read More
Vincent, Dickson, and Daniel explain how trypanolytic factor forms membrane channels to lyse trypanosomes, and present a new case study.
