Most of us carry a mental picture of DNA in its iconic form – the famous double helix unveiled by Francis Crick and James Watson. But researchers are beginning to develop a new picture of DNA that shows the molecule’s more dynamic side, which is capable of morphing into a large number of comple... Read More
There are more microbes on Earth than there are stars in the universe. They occupy every ecological niche, from deep-sea vents to the human gut. So you'd expect them to be staggeringly diverse. But the latest studies suggest there may be far less variation than thought.

Guys, what a great podcast. I am a chemical engineer with a MS in Environmental Management. I have been doing EH&S work in industrial settings for about 20 years after some years in R&D and manufacturing positions. I have always had a stro... Read More
Influenza viruses evade infection-fighting antibodies by constantly changing the shape of their major surface protein. This shape-shifting, called antigenic drift, is why influenza vaccines -- which are designed to elicit antibodies matched to each year's circulating virus strains -- must be ref... Read More
From fungi to flies, some parasitic species have figured out how to control their host's behavior to get what they need. See what happens when bugs go really bad with this slide show from Scientific American. Read More

In some African villages, nearly everyone is infected with Mansonella perstans, a parasitic worm that’s remarkably hard to kill. It’s resistant to standard anti-worm medications, but researchers have learned that an old antibiotic can vanquish the tiny beasts — in a roundabout way.
The parasi... Read More
The human body contains billions of microorganisms, and microbial cells found in the human gut are estimated to outnumber human cells by ten-to-one in healthy adults. However, little is known about the ways in which these minute life forms influence health and disease.
That is why gastroenter... Read More
