Your body usually does a great job defending you from all kinds of viruses, fungi, and bacteria. However, there are some pathogens out there that can hide from your immune system and stay dormant in your body, waiting for their...

Since the 1970s, researchers have engineered superbugs. While this research could help us prepare for future outbreaks, the stakes of this work are extremely high: if even one dangerous virus escaped a lab, it could cause a global...

Paul Andersen explains how changes in the signal transduction pathway can affect organisms. He begins with a brief discussion of the tetrodotoxin produced by the California Newt and then explains how anthrax affects adenylate cyclase...

Let's face it: Humans are pretty messy. Industrial processes like mining and manufacturing are important parts of keeping civilization going, but they all impact the environment. Sometimes that impact is particularly big and messy,...

Why Don't Scavengers Get Sick?

(NOTE: This talk was given in 2009, and this field of science has developed quickly since then. Read "Criticisms & updates" below for more details.) Drug-resistant bacteria kills, even in top hospitals. But now tough infections like...

British scientists have developed a portable, fully automated test lab that can rapidly detect biological warfare agents and infectious diseases. This innovative system uses the polymerase chain reaction to amplify DNA and provide...

Join us as we explore the incredible life and groundbreaking discoveries of Louis Pasteur, the father of microbiology. From his early experiments in fermentation to his development of pasteurization, Pasteur's work revolutionized science...

Why did the US military dig a tunnel in the Alaskan tundra? What is the tunnel used for now?

It explains infections caused by disease-causing microbes and describes methods of food preservation.

In this video, Jabzy brings us historical tidbits and unknown facts about Kazakhstan's Nuclear Problem

Most of us know about anthrax either because of the terrorism involving sending anthrax in the mail, or because of the metal band by the same name. But let's get a closer look at the actual bacterium, Bacillus anthracis.
