The achilles heel of the influenza virus: Ubiquitin protein may be an approach for future medicines

Sciencedaily.com 

Influenza viruses are becoming increasingly resilient to medicines. For this reason, new active ingredients are needed. Important findings in this regard have been provided: for the virus to proliferate, the polymerase of the influenza A virus has to be modified many times through enzymes in the host cells. The team of researchers was able to produce a comprehensive map of types of modification. Medicines directed against the enzymes woud be resilient to rapid mutations in the virus, thus offering great potential for the future.

Head injuries could be a risk factor for developing brain cancer

Sciencedaily.com 

Previous studies have suggested a possible link between head injury and increased rates of brain tumors but evidence has been limited and often inconclusive. A team has now identified a possible mechanism to explain this link, implicating genetic mutations acting in concert with brain tissue inflammation to change the behavior of cells, making them more likely to become cancerous. Although this study was largely carried out in mice, it suggests that it would be important to explore the relevance of these findings to human gliomas.
