Scientists discover first nitrogen-fixing organelle

Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria ...

Precise transcript targeting by CRISPR-Csm complexes

Mammalian cells are inherently complex due to subcellular compartments, thereby making the process of robust transcript targeting of nucleic acids somewhat challenging in the molecular biology lab. In a recent report now ...

Cell death shines a light on the origins of complex life

Organelles continue to thrive after the cells within which they exist die, a team of University of Bristol scientists have found, overturning previous assumptions that organelles decay too quickly to be fossilized.

Complex life a billion years earlier than thought?

Researchers said Tuesday they had uncovered fossils showing that complex life on Earth began more than 1.5 billion years ago, nearly a billion years earlier than previously thought.
