A large team of researchers from the World Health Organization (WHO) and many other institutions performed a new analysis of serologic studies from 19 countries in order to estimate the infection rate of the 2009 H1N1 influenza during the first year of the pandemic. The study, published in Influenza and Other Respiratory Viruses, showed that about 24% of the population were infected with the H1N1 virus during the first wave of the pandemic. Of these infected, approximately 0.02% died.These results are slightly higher than the official estimates made by the US Centers for Disease Control and Prevention (CDC) in the period immediately following the outbreak of the virus, and confirm the age-related distribution of H1N1 incidence, with the children being the most affected when compared to the over 65. One of the possible limitations of the study, as highlighted by the authors themselves, is that the vaccine might had little impact on their results, due to conflicting results and low vaccine coverage in most countries.

Europe embraces the hydrogen challenge
The agriculture wealth does not lie only in food supply, but also in waste production. A European project, started in 2012 and close to its end, has faced the problem of organic waste reuse and, at the same time, the challenge of fuel production from natural and low-environmental impact sources. HyTime obtained an European contribution of 1,609,026 euros under the 7th Framework Program. The project, led by the Netherlands, is the result of
