Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany and at University of Virginia School of Medicine have revealed a new cellular adaptation to starvation, in which the mitochondria of yeast cells get coated by ribosomes. Surprisingly, the ribosomes attach to the mitochondrial outer membrane with a very unusual 'upside-down' orientation. The discovery of this mechanism has potential implications for our understanding of how stressed cancer cells survive starvation.

Until now, it was considered certain that people are more likely to cooperate if the benefits from cooperation are higher. A recently published, large-scale study has now called this finding into question: in over 2000 study participants, the researchers found no relationship between benefits from cooperation and willingness to cooperate.

Researchers have now discovered that DNA sequence changes known to increase a person's risk for diabetes are linked to how well pancreatic cells can handle two different kinds of molecular stress. In people with these DNA changes, the insulin-producing cells in the pancreas may be more likely to fail or die when exposed to stress and inflammation.
