ADN. El detector de mentiras

In the beginning, Earth was an inhospitably alien place―in constant chemical flux, covered with churning seas, crafting its landscape through incessant volcanic eruptions. Amid all this tumult and disaster, life began. The earliest living things were no more than membranes stretched across microscopic gaps in rocks, where boiling hot jets of mineral-rich water gushed out from cracks in the ocean floor. Although these membranes were leaky, the environment within them became different from the raging maelstrom beyond. These havens of order slowly refined the generation of energy, using it to...

Soil is a pivotal component of the environment and the maintenance of soil quality is critical for ensuring the sustainability of the environment and the biosphere. The use of fertilizers has increased at a faster rate than global food production. Modern agriculture is dependent on phosphorus derived from phosphate rock, which is a non-renewable resource. It is needed to improve P acquisition efficiency for both low input and intensive agroecosystems. However, few studies have focused on cereal-legume interactions with regard to soil P. The objective of this work was to study the effects of...

Nuestro universo parece extrañamente "biofílico", es decir, idóneo para el desarrollo de la vida. ¿Es casualidad, providencia o coincidencia?

Este libro cautivador explora las fascinantes consecuencias que se derivarían de que la respuesta fuera afirmativa. Rees plantea la hipótesis de que nuestro universo puede ser sólo parte de un extenso "multiverso",...
