More than 1.6 billion years ago, one cell engulfed another and put it to work. More specifically, a eukaryotic cell, the sort of cell that contains distinct structures with different functions, took in a blue-green bacterium that could do something it could not: use sunlight to make sugars. The ... Read More
Amoebae — a group of amorphous, single-celled organisms that live in the human body — can kill human cells by biting off chunks of intestinal cells until they die, a new study finds. This is the first time scientists have seen this method of cell killing, and the new findings could one day help ... Read More
Scientists are closer to establishing a definitive bacterial cause for the skin condition rosacea. This will allow more targeted, effective treatments to be developed for sufferers, according to a review published in the Journal of Medical Microbiology.
Rosacea is a common dermatological cond... Read More
Placement of copper objects in intensive care unit (ICU) hospital rooms reduced the number of healthcare-acquired infections (HAIs) in patients by more than half, according to a new study published in the May issue of Infection Control and Hospital Epidemiology, in a special topic issue focused ...

The human “microbiome”—the trillions of bacteria, yeasts, and other microscopic creatures that live inside a human body—has been one of the major science stories in recent years. It seems that barely a week goes by that we don’t learn something new about the relationship between the human body a... Read More
Vincent, Rich, and Kathy and their guests Clodagh and Ron recorded this episode at the 33rd annual meeting of the American Society for Virology at Colorado State University in Ft. Collins, Colorado.
