Powerful and versatile new genetic tools will assist in safeguarding both European fish stocks and European consumers. A new article details the first system shown to identify populations of fish species to a forensic level of validation.

Does polyploidy play a role in the onset of the Italian endemic flora?
5/22/2012 3:46:22 PM
Plants show a higher variation in chromosome numbers than animals do, mainly because of polyploidy -- the occurrence of more than two sets of chromosomes. In plants, polyploidy can cause reproductive isolation and the consequent onset of new species. Researchers now set out to estimate to what extent polyploidy is involved in the onset of the Italian endemic plants.

How Staph bacteria gain resistance to last-line drug
5/22/2012 3:46:22 PM
Scientists have determined the genome sequences of a dozen strains of Staphylococcus aureus bacteria known to be resistant to vancomycin, an antibiotic of last resort. The researchers demonstrated that resistance arose independently in each strain, and identified shared features among the strains that may have helped them acquire vancomycin resistance and evade human immune defenses.

Marine aquarium fish trade study reveals fewer fish, more species imported than previously estimated
