BactoBeads™ are non-pathogenic, freeze-dried microbes (bacteria and lower eukaryotes) that are easily cultured for use in the classroom. Each bead contains microorganisms, buffer, salts and nutrient broth in an instantly soluble pellet.
Can Beauty Sleep Fight the Common Cold?
Getting a full night’s sleep could be more important than simply preventing groggy, sluggish mornings. According to a recent study conducted by researchers at the University of California San Francisco, Carnegie Mellon University, and the University of Pittsburgh Medical Center, the amount of sleep that people receive directly correlates with their resistance to getting sick.

Seasonal Variations in Gene Expression
A lot changes in the fall – temperatures, leaf colors, coffee flavors, sunrise time, TV shows, it's a long list. Add to this list your transcriptome. A transcriptome is the set of all RNA molecules in a cell or population of cells. The name comes from transcription, which is the first part of gene expression where information in a strand of DNA is copied into messenger RNA. The DNA information in a eukaryotic organism, e.g. the genome, is more or less constant apart from the occasional mutation. In contrast the transcriptome is in constant flux.

Edvotek Road Trip - A Brief Tour of the West Coast!
A few weeks ago, Edvotek kicked off our Fall Conference Schedule by attending the yearly meeting for the California Science Teachers Association in Sacramento, California. Before the conference started, we had time to wander around the city and take in the sites. Our first stop was Old Sacramento, which is the oldest part of town. We had fun wandering the cobblestone streets and the historic buildings. In fact, we stopped at the B. F. Hastings Building, which served as the western terminal of the Pony Express. We also toured the historic California State Capitol.

DNA Ligase - Building a Bridge with DNA
DNA ligase is one of the most important, but least celebrated, enzymes used in modern biotechnology. This enzyme plays a very important role in DNA replication and repair by acting like a “glue” that can connect different DNA fragments to one another. Scientists take advantage of this molecular glue to combine DNA fragments to make an entirely new sequence. However, many people are merely using DNA ligase as a tool without knowing the story and mechanism behind it.

Visualizing DNA After Agarose Gel Electrophoresis
Electrophoresis is a technique that allows us to separate DNA, RNA or proteins into bands according to their size. For more information about this technique, be sure to check out our previous post describing electrophoresis.
