King has recently extracted the biochemical machinery that certain types of bacteria use to convert nitrogen in the air to ammonia. Put this into a solution, bubble through nitrogen and add a cadmium sulphide semiconductor and you have adeconstructed artificial leafwith a twist: it now eff...

Almost all living organisms are dependent on soil. Some depend directly, while some depend indirectly . Plants need soil four getting support as well as nutrients to prepare their food. On the other hand, organisms depend on plants for food and othe
All living matter absorbs carbon from the atmosphere, including an amount of radioactive carbon-14. It is mostly found in atmospheric carbon dioxide because that is where it is constantly being produced by collisions between nitrogen atoms and cosmic rays. What can carbon-14 dating be used for?
Nitrogen, an element that is essential for all living cells, makes up about 78 percent of Earth’s atmosphere. However, most organisms cannot make use of this nitrogen until it is converted into ammonia. Until humans invented industrial processes for ammonia synthesis, almost all ammonia...
