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.

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.

Edvotek Visits the City of Brotherly Love
Edvotek recently had the opportunity to participate in the NSTA area conference in Philadelphia. Surprisingly, it was the first opportunity for many of our team members to visit this marvelous city, so we made sure to arrive early to explore. We were amazed by all of the history on display, contributing to Philadelphia’s designation as the sole World Heritage City in the United States, a privilege enjoyed by only 250 cities around the world.

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.
