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.
The Genetics of Speech
For centuries, scientists and philosophers have argued that speech, a distinctly human trait, was an essential component for the formation of early societies. Ancient mythologies often suggest that language predates humanity, while biologists have uncovered interesting links that might explain the evolutionary development of human speech.

Five Ways to Improve Your Transformation Experiments
Transformation is the process through which bacteria can pick up foreign DNA from the surrounding environment. The newly acquired genetic information is both stable and heritable. In the laboratory, we can transform bacteria with small, circular pieces of DNA called plasmids. These plasmids are engineered to contain genes from different sources. Once transformed into bacteria, the plasmids turn the bacteria into living factories to create medications, vitamins and other useful products.

Biotechnology Basics - qPCR
PCR exponentially amplifies copies of a DNA sequence and it’s great at producing more DNA for subsequent analysis. For example, PCR combined with gel electrophoresis can tell us whether a particular loci is present or absent. It’s also somewhat of a black box - you put your sample in a thermal cycler, program in the cycles’ temperatures, and later on come back and collect your product. We know what happens in between but we can’t see it happening in real time.

Top 100 Papers in Biotechnology -- and How to Bring Them Into Your Classroom
In order to communicate their findings to others in their field, scientists will publish their data in peer-reviewed journals. Some of the techniques within these papers have revolutionized the way we do science. Recently, a leading science journal tabulated the top 100 most cited scientific research articles ever. Many of the techniques within these papers are used in the research lab every day!

The Evolution of Plants
From still unknown flowers, trees, ferns and mosses in the rainforest to the vegetables and grain we eat at home, plants share a deep and in many ways still mysterious history. This history has shaped the evolution of the other kingdoms as well as the physical properties of Earth itself.
