How a cell's mitochondria make their own protein factories

Ribosomes, the tiny protein-producing factories within cells, are ubiquitous and look largely identical across the tree of life. Those that keep bacteria chugging along are, structurally, not much different from the ribosomes ...

Researchers discover how a nano-chamber in the cell directs protein folding

A landmark study by researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University reveals how a tiny cellular machine called TRiC directs the folding of tubulin, a human protein that ...

How cells gain control over their bacterial symbionts

Modern eukaryotic cells contain numerous organelles, which once used to be independent bacteria. In order to understand how these bacteria were integrated into the cells in the course of evolution and how they are controlled, ...

New branch on tree of life includes 'lions of the microbial world'

There's a new branch on the tree of life and it's made up of predators that nibble their prey to death.

Long-standing genomic mystery about the origins of introns explained in new study

One of the most long-standing, fundamental mysteries of biology surrounds the poorly understood origins of introns. Introns are segments of noncoding DNA that must be removed from the genetic code before it is translated ...

'Primordial super-enhancers' provide early snapshot of the mechanisms that allowed for multicellularity

New research at the University of Chicago has found that the same machinery used by mammalian cells to drive cellular differentiation also plays a critical role in activating genes in yeast in response to environmental stress.

Sequencing project to unleash the biotechnological potential of single-celled algae

An ambitious plan to sequence the genomes of all known species of euglenoids over the next decade has been launched today. The network of scientists behind the initiative believe it has the potential to drive breakthroughs ...

Gene-reading enzyme razes and rebuilds DNA-winding structures in its path

RIKEN researchers have shown how a gene-reading enzyme manages to dismantle bead-like structures of DNA and reassemble them at high speed, without disrupting the integrity of genomic organization. Their findings, now published ...

Researchers reveal the structure of the IFT-B complex, essential for formation of the cilium organelle

Cilia are organelles that provide eukaryotic cells with motility, sensory reception and intracellular transduction of external stimuli. They are constructed and maintained by the bi-directional movement of 22 different proteins ...

Enzymes in human cells probably evolved from primordial organisms

A team of researchers at UmeƄ University has discovered that an enzyme in human cells has probably evolved from an ancient single-celled organism. The enzyme's unique properties mean that it could be used as a building block ...
