Auto-Brewery Syndrome

We all have bacteria and yeast that live in our gut and you've probably read about them here! For most of us, we live in relative harmony with these tiny guests. But sometimes, either due to our immune systems malfunctioning or lifestyle changes (like when we take antibiotics), yeast that ferment ethanol start to grow…

The CRISPR-Cas System

It's about time I covered CRISPR, don't you think? It's the hottest topic in science since space-tardigrades! Once again, no, water bears can't live in space naked, they have to be in a dry tun. Back to CRISPR though, this new gene editing technology isn't actually new at all. Bacteria have been using it as…

Quorum Sensing

Chattering Bacteria Ever notice how animals are able to communicate, move, hunt, and travel in large groups? Bacteria are no different. Quorum sensing, in the simplest sense, is bacteria chatter. Instead of using words, they use chemicals. Once these communication chemicals build up to a certain level, they affect gene expression and transcription. Antibiotic Resistance…

The secret to Europe's room temperature dairy products is sterilization and vaccinations. Milk Bacteria While pasteurization kills most of the bacteria…

The Lambic: Belgian Microbe Magic

Hundreds of yeast and bacteria in the air (the "open" part) are responsible for brewing (the "fermentation" part) a very special kind of beer called the lambic. Unlike other breweries you may have visited, this one has no…

Why Fecal Transplants

The Poop Post Oh yes, this is the post about poop. Or rather, doing fecal transplants. While it is a gross topic, your waste products say a lot about the health of your entire body system. Trillions of bacteria and yeast cells colonize your large intestine, skin, mouth, air ways, and vagina. They not only…
