In the movie, “Signs”, one of the characters, Bo, has an interesting habit of leaving half-full glasses of water lying around the house. To Bo, the water “tastes funny” after she drinks only a few sips of it. This odd habit becomes instrumental in the story’s ending. (I will not spoil it for those of you who have never watched this film!)
Incidentally, water can taste funny due to substances and/or forms of life found in it. Too bad Bo wasn’t a scientist. Perhaps she could have extracted DNA from each glass of water and found out the kinds of organisms More >
Could the meat in your plate pose a health risk for you? If the animal where it came from was properly raised and handled, and the meat went through a sanitary inspection before reaching your plate, there is little chance it can cause you a health problem. But, what could happen if a sanitary authority has not inspected it?
Your meat indeed could be a high risk for your health. In some cases this can be a public concern, because meat can be a source of pathogens that could cause a disease outbreak. In fact, it has been documented that close interaction More >
Welcome to our new DNA barcoding blog. It truly is an exciting time to be involved in this aspect of genomic science as DNA barcoding has been used to identify new species, help explain the biodiversity of our planet and even detect food fraud. Just as a universal product code (UPC) identifies an item for sale in a store, a DNA barcode uniquely identifies each species of living thing. The DNA barcoding technique includes extraction of DNA from an organism of interest, ampliflication of this DNA through PCR (Polymerase Chain Reaction), and sequencing of the DNA at specific locations in More >
