The last advances in genetics and genomics are leading a change in the paradigm about how to treat diseases. Epigenetics is the science field that studies how gene expression is regulated. Several modifications on the genes such as DNA-methylation, histone-acetylation or microRNA (miRNA) regulation are considered to be the main responsible in controlling gene expression […]

Nowadays there are still people that believe in destiny. However the scientific community more and more is bringing light to that subject showing that although the genetic material could program ourselves to suffer some pathologies, the day-to-day experiences are the ones that lead us towards a healthy or pathological aging. And how is that? Our […]

Think on a cell, it is alive and, among other things, it lives to reproduce itself. The paradigm of cell division is the mitosis, a wonderful dance orchestrated to equitably distribute the possessions of the mother cell: molecular structures, machinery and, especially, the genetic material. Prior to distribute, a good mother always amasses a fortune […]

There is a strong tendency to consider that every scientific or technical solution to a particular problem is irrefutable. Nowadays, scientific and technological knowledge usually eludes public criticism and even we have seen how important government decision making were made by the so-called technocrats. We often forget the contingency of this knowledge, the fact that […]

When the general media report news about genetics, there is a deplorable tendency towards gene determinism. Headlines in the vein of “Gene for X discovered”—where X is anything from a physical trait to a complex behavior—are regrettably common, and almost always incorrect. That’s why I face this article with some trepidation. Because, you see, there […]
