Planaria Ripping Themselves Apart

Planaria are little flatworms with triangle heads, beady eyes, and the ability to regenerate after being cut in half. Bet you didn't expect that last part, did you? Unlike cell division, planarian fission is violent and ... well, weird. To stimulate these little guys to split, you have to first decapitate them. Unlike mitosis, planarian…

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…

Getting Through Tough Times

Living organisms have come up with lots of interesting ways to get through tough times. Sometimes, "tough" means stuff like... winter. Other times, there might be a food shortage or the puddle dries up. Whatever the stressor, being adaptable is the key to survival. In this post, we'll take a look at how 3 weird…

Holding Up the Line: RuBisCo

With all the extra CO2 we've been putting into the atmosphere since the Industrial Revolution, the age of global warming is finally upon us. In our scramble to find new sources of energy, some scientists have turned to algae. The logic is there: plants take CO2 and make O2. More plants = less CO2. It's…

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…

Nanoparticles

Tiny UPS... or something You've learned about phage therapy, quorum sensing and quorum quenching, which means, hello PhD! I'm just kidding, no grad student has the time to jump from topic to topic like this. But for us curious nerds, the next topic in the fight against antibiotic resistant bacteria is nanoparticles. Specifically, using them…

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…

Sterilization of Milk

Ah! Milk on the Shelf If you've ever traveled to Europe, you'll notice something interesting. In the grocery stores, milk and eggs sit out in the aisles unrefrigerated. What kind of magic is this?! The secret to Europe's room temperature dairy products is sterilization and vaccinations. Milk Bacteria While pasteurization kills most of the bacteria…

The Lager Story

The German Lager Compared to the Belgians, German beers are rather monotonous. Instead of using ale yeast, lager yeast (a more chilled out yeast) is used in the brewing process. There are two historical events to thank for all this: a beer purity law and a duke. The law was called the Reinheitsgebot and it…
