The BiotechnologyEducation Company
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.
Taking Transformation to the Next Level With Colony PCR
Transformation is a biotechnology technique that is used daily in research laboratories around the world. This technique allows scientists to force E. coli to take up small, circular pieces of DNA called plasmids from the surrounding environment. Using recombinant DNA technology, these plasmids are engineered to contain genes from different sources.

DNA Sequencing to Save Endangered Species
Since the 1980’s, DNA evidence has been used in the criminal justice system to help convict violent offenders and, just as importantly, exonerate innocent individuals. An approach often used is DNA profiling, a technique where investigators compare the base pair order of DNA found at the crime scene to a suspect’s DNA. Now, another type of genetic analysis – DNA barcoding – is being used to combat illegal wildlife trading.

Detecting the Silent Killer - Understanding Diabetes
Diabetes, known officially as diabetes mellitus (DM), is a common but severe long-term metabolic disease. The World Health Organization’s 2014 data indicates that about 9% of the global adult population (age > 18) suffered from this disease and more than 1.5 million people died from complications caused by diabetes. Governments and private companies invest huge amounts of money into research to fight diabetes each year.

Edvotek at the International Space Station
Who doesn’t dream of visiting space? Few people throughout history have had the chance to experience zero gravity and to observe the world from thousands of miles away. Since 2010, the Student Spaceflight Experiments Program (SSEP) has provided an opportunity for American and Canadian students to design and fly microgravity experiments in low earth orbit. As of 2015, SSEP has sponsored eight missions for elementary through university aged students, two onboard the Space Shuttle and six to the International Space Station (ISS).

Sequencing Tardigrade DNA Reveals Unexpected Results
Recently, tardigrades (known by some as moss piglets and others as water bears) have been making headlines in the field of genetics. What are these excellently nicknamed critters? They are very small aquatic animals. A quick search will show some amazing pictures (and videos). Imagine a less than 1 mm animal with a head attached to a barrel shaped body and four pairs of clawed legs. Interestingly, the hindmost legs are orientated differently from the front six - one useful way to distinguish them from other microscopic animals. Inside they have digestive, excretory, and nervous systems.
