A somewhat greater proportion of life scientists were studying the behavior of subcellular organelles, isolated or in situ. Such materials are utilized by scientists, except the ecologists, in all research areas and, as one might expect, are a principal preoccupa- tion of cell biologists and biochemists.

Scientists have been attempting to recreate some semblance of the chemical origin of biomolecules for decades; it was 70 years ago that Stanley Miller, a chemist at the University of Chicago in Illinois, sparked a gas mixture to create organic compounds 4 . Researchers including Carl Woese and Francis Crick suggested the ribosome could have started...
Regardless of how the hypothetical protoribosome came to be, at the time when Agmon and Yonath first conceived it, there was no experimental evidence to show that it could have existed and worked as they thought it did. The protoribosome hypothesis assumes that one of those early RNA pockets could link amino acids together, and that it then evolved...
By the time Krupkin was trying to measure a dipeptide product, the Yonath group wasn’t the only one on the trail of the minimal peptide-bonding machine. Tamura, in Japan, was also inspired by the semi-symmetrical core pocket. He recruited a group including master’s student Mai Kawabata and undergraduate Kentaro Kawashima to make their own protoribo...
The life sciences embrace a great array of intellectual activity, a continuum extending from the search for the origin of life and the detailed structure of the macromolecules that make life possible to understanding of the total ecology of planet Earth.

Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others.
