Me and my microbes In the past decade or so, the microbiota, the community of microbes that makes its home in the guts of humans and other animals, has become quite a popular research topic. Quite rightly so, since our little guests seem to affect aspects of our lives that we wouldn’t necessarily consider to […]... Read more »

Life on Earth was born in water. Then, about half a billion years ago, the first organisms stare colonizing lands that offered new spaces, less predators and, in time, abundant oxygen and nutrients. Still, the indissoluble bond that living organisms had with water remained, and in order to survive in this new environment plants and animals had to develop anatomical, physiological and behavioral adaptations to better obtain, manage and save water. Plant bodies, as well as ours, are mostly made of........ Read more »
