Researchers have discovered a type of organelle, a fundamental cellular structure, that can turn nitrogen gas into a form that is useful for cell growth. The discovery of the structure, called a ...

Biology textbooks state that of the three main biological divisions of the world, bacteria, archaea, and eukaryotes, only some bacteria and archaea are capable of nitrogen fixation, which converts ...

The complex cells that underlie animals and plants have a large collection of what are called organelles—compartments surrounded by membranes that perform specialized functions. Two of these were ...

Most organisms require nitrogen to produce biological molecules, such as nucleotides and amino acids, but until recently, only prokaryotes were known to fix nitrogen from the atmosphere. “It’s a very ...

A group of researchers has won a large science prize for a discovery not quite two decades in the making. It was long thought that only simple microbes had mastered a chemical conversion reaction that ...

A new part of an ocean plant cell has been discovered that might revolutionize farming one day. The structure can take nitrogen and convert it... A cell pulls off one of the 'Holy Grails' of ...
