<p><strong><a href="http://tornillosygenes.com/" target="_blank" title="Tornillos y Genes">Tornillos y Genes</a></strong> (Screws and Genes) is the first blog about Synthetic Biology written in Spanish. This way, we want to spread the last advances in this discipline to the Spanish speaking people, a huge community formed by 500 million people (ref: <a href="http://en.wikipedia.org/wiki/List_of_languages_by_number_of_native_speakers" target="_blank" title="List of languages by number of native speakers">List of languages by number of native speakers</a>).  Since its start in March, our blog has received more than 11.000 visitors:  they could read about topics like the <a href="http://tornillosygenes.com/2011/06/02/el-catalogo-de-partes-biologicas/" target="_blank" title="Main Registry of Parts">Main Registry of Parts</a>, <a href="http://tornillosygenes.com/2011/04/09/el-repressilator/" target="_blank" title="The Repressilator">the Repressilator</a>, <a href="http://tornillosygenes.com/2011/03/30/estandarizacion/" target="_blank" title="standardization">standardization</a>, <a href="http://tornillosygenes.com/2011/05/02/origami-de-adn-i/" target="_blank" title="DNA origami">DNA origami </a> and different themes from <a href="http://tornillosygenes.com/2011/05/05/myxococcus-xanthus-una-bacteria-con-instintos-de-lobo/" target="_blank" title="myxococcus xanthus">microbiology</a> and <a href="http://tornillosygenes.com/2011/04/16/los-gatos-tricolor/" target="_blank" title="Tricolor cats">genetics</a>  to <a href="http://tornillosygenes.com/2011/05/19/introduccion-a-la-mineria-de-datos/" target="_blank" title="Data Mining">informatics</a>. Moreover, we tag the different articles with a symbol indicating the (engineering or biological or both) difficulty (from one to three): our aim is to create a blog that everyone can find interesting, so we write some complex articles to experienced people and easy articles that anyone can read.</p>
