DNA News and Research

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Protein complex proves valuable for changing cell fate

The DNA contained within each of our cells is exactly the same, yet different types of cells - skin cells, heart cells, brain cells - perform very different functions. The ultimate fate of these cells is encoded not just in the DNA, but in a specific pattern of chemical modifications that overlay the DNA structure.

Toxic chemicals make us susceptible to a wide range of diseases

From the Industrial Revolution and onward, the world has become an environment that is overflowing with dangerous toxins. Mass manufacturing has resulted in thousands of chemical pollutants being released in the atmosphere, water, and soil. As well, there has been a widespread increase of chemicals being added to almost every type of food and retail product.

Swedish study opens new potential for combating resistant bacteria

Neisseria meningitidis, the meningococcus, is a bacterium that can cause diseases with high fatality rates, and there has therefore been considerable concern that, like other bacteria, it might become resistant to antibiotics. But now a study from örebro University and örebro University Hospital in Sweden shows that there has not been any increase in resistant meningococci in Sweden over the last 15 years. According to researcher Sara Thulin Hedberg, the reason for this may be that it is not especially advantageous for bacteria to develop resistance.
