A research consortium has generated the broadest look yet at the proteins that make up mitochondria, capturing the organelle's diversity across multiple branches on the tree of complex life. With major contributions from ...
Asgard archaea, our closest known microbial relatives, play a key role in current models of the origin of more complex organisms, known as eukaryotes (all animals, plants, protists and fungi). However, their biology has so ...
In acute, life-threatening infections, rapidly characterizing the microorganisms in a patient sample can help guide diagnosis and treatment. Computational methods known as taxonomic profilers can analyze metagenome sequencing ...
Every time a cell divides, its chromosomes must be distributed correctly between the two daughter cells. Central to this process is the centromere, a specialized region of the chromosome. The centromere serves as the attachment ...
A study conducted by the University of Liège and Rockefeller University reveals, with near-atomic precision, the three-dimensional structure and function of a gigantic molecular machine essential to the survival of trypanosomatid ...
A tiny, single-celled organism can thrive at temperatures that would kill all other known complex life. In a study published in Cell, scientists describe a new species of amoeba that can eat and reproduce in hot spring water ...
A synthetic biology technology has been developed that converts easily degraded messenger RNA (mRNA) into a ring-shaped form inside microbial cells, increasing protein production.
Cells rely on complex signaling networks in which different molecular pathways communicate with one another. Small GTPases act as molecular switches in these networks, controlling diverse cellular processes such as intracellular ...
After an injury, DNA not only changes its activity but also the way it is organized spatially within the cell nucleus. In this process, certain regions of DNA establish new physical contacts through chromatin loops that act ...
A process known as the biological carbon pump (BCP) moves organic carbon from near the ocean's surface to the ocean floor. That carbon often stays there for hundreds or thousands of years, making the BCP a primary source ...
