Quality control is vital for the energy production of cells

Mitochondria generate most of the energy cells need through a respiratory chain for which they must produce their own proteins. The research group of Associate Professor Henna Tyynismaa, University of Helsinki, Finland, has ...

In a role reversal, RNAs proofread themselves

Building a protein is a lot like a game of telephone: information is passed along from one messenger to another, creating the potential for errors every step of the way. There are separate, specialized enzymatic machines ...

Researchers create Methuselah fly by selecting best cells

A team of researchers at the University of Bern has managed to considerably prolong the lifespan of flies by activating a gene which destroys unhealthy cells. The results could also open new possibilities in human anti aging ...

New defense mechanism against viruses discovered

Researchers have discovered that a known quality control mechanism in human, animal and plant cells is active against viruses. They think it might represent one of the oldest defense mechanisms against viruses in evolutionary ...

Quality control of mitochondria as a defense against disease

Scientists from the Montreal Neurological Institute and Hospital in Canada have discovered that two genes linked to hereditary Parkinson's disease are involved in the early-stage quality control of mitochondria. The protective ...

How quality control works in our cells

A cellular control mechanism prevents the production of defective proteins in our cells. A team of researchers from Bern has now obtained valuable insights into this vital mechanism that could lead to new therapeutic approaches ...

Wikipedia losing editors, study says

Wikipedia, one of the world's biggest websites, is losing many of its English-language editors, crippling its ability to keep pace with its mission as a source of knowledge online, a study says.

Old Cells Work Differently

The agglutination and accumulation of proteins in nerve cells are major hallmarks of age-related neurodegenerative illnesses such as Alzheimer's disease. Cellular survival thus depends on a controlled removal of excessive ...
