Microbes, or microorganisms, are tiny living beings that cannot be seen by the naked eye. These little guys are one of the oldest living things on Earth, and are extremely diverse in how they live and what they can do. They, for example, can live in many places, from the freezing iciness of glaciers, to the insides of other organisms, like termites or humans. Since they are virtually everywhere, microorganisms are essential for the biological processes that allow plants and animals to breath, eat and thrive. But how were they able to endure, adapt and flourish constantly over millions of years? The secrets of their success are still within them, coded into their genomes, waiting for us to understand them. Now, genomes, bacterial or otherwise, are the repositories of life. These repositories store almost every bit of information that allows living beings to live in discrete units called genes. Genes are strung together like the sentences in a book, interacting with each other to create meaning, saving the story of that particular book—or that particular living organism’s genome—so it can be copied, modified, corrected or enhanced, and then passed on to new generations. After many, many years of studying these “books,” we have learned to read and understand them, thanks to the technological innovations of the last decade. Nowadays, it is possible to get the full genomic sequence of practically any organism, and compare it with thousands of genomes from other organisms, letting us peek at the secrets that make each organism who it is. With the current technical abilities, the challenge now is not to obtain the information but to interpret all those chunks of the story. Finding ways to untangle the riddles of genomic information is the work of Genomics, the science that allows us to obtain, analyze and prioritize information among the many stories that we sequence everyday. To do this, Genomics draws from many sciences, like mathematics and computing sciences, making it a truly interdisciplinary endeavor. Right now , genomics are one of the most important areas of biology, and many, if not most, of current biological studies use at least a little bit of genomics. For example, genomics can be used to identify a microbe and give it a name, to learn about what types of things it can do or places it can live, and to figure out the mechanisms that enable it to survive under particular conditions. Here, we will dwell on some of the basic questions about microbial adaptation, biodiversity, and their relationships with other living beings using a genomic approach. We will also focus on the environment, trying to understand how such tiny little creatures are capable of solving their daily problems, and how they can alter the places in which they live. Learning about these mechanisms will not only provide us with knowledge about life in general but will also help us to understand these organisms as a fundamental component of our ecosystem, including their harmful and beneficial effects in all aspects of our daily life, which can be translated into useful applications in almost any imaginable way.

Let Them Eat Dirt
Our over-sanitized world threatens children’s health, but parents can change their environment into one where they’ll thrive. Babies and young kids are being raised in surroundings that are increasingly cleaner, more hyper hygienic, and more disinfected than ever before. As a result, the beneficial bacteria in their bodies is being altered, promoting conditions and diseases such as obesity, diabetes, asthma, allergies, and autism. As Let Them Eat Dirt shows, there is much that parents can do about this, including breastfeeding if possible, getting a dog, and avoiding antibiotics unless necessary—and yes, it is OK to let kids get a bit dirty.
