2016-10-12T11:09:33ZAlthough genetically modified (GM) food has been on supermarket shelves for almost 15 years, there is still extensive controversy about whether it is safe. Anti-GM group continue to sound the alarm regarding its potential risks dangerous. Why is there such controversy about GM food and crops and is there still a reason to be concerned about its safety? Take a look at this article to get an overview of what is driving this discussion.
2016-10-12T11:09:33ZThe second of two controversial papers on the bird flu (avian influenza A/H5N1 virus) was published on June 22 in Science. There was a lot of concern whether these studies should be made public. Both studies provide important information about mutations that make the bird flu more infectious and more deadly and could be conceivably be used to design more pathogenic versions of bird flu. However, the work also provides a better understanding of viral biology and pathogenicity.
2016-10-12T11:09:33ZDNA analysis has become accessible enough to enable convenient genetic characterization of large numbers of pathogen samples collected from patients around the world. As a result, they can track how new strains of virulent bacteria have evolved into global pandemics. The article discusses two examples of this sort of analysis, and what the findings suggest about how bacteria continues to adapt and thrive in the modern world.
