Frequent nightmares linked to faster aging and premature death

INTRO: People who have weekly nightmares are three times more likely to die earlier than those who rarely or never experience them, according to a new study. Researchers from Imperial College London looked for a link between how regularly someone experiences bad dreams and the rate at which their cells age.
They studied more than 183,000 adults aged from 26 to 86, as well as 2,400 children aged between eight and ten, and asked them, or their parents, how often they had nightmares. The participants were followed for a period of between 18 months and 19 years.
The research showed that those who had bad dreams once per week or more had shorter telomeres, the cap-like structures at the end of chromosomes that play a key role in cell division and ageing. Shorter telomeres are associated with a faster rate of cellular ageing.
They also found that those who experienced regular nightmares were three times more likely to die before the age of 70 compared with those who did not... (MORE - details)
Researchers discover how caffeine could slow cellular ageing

INTRO: A new study from the Cellular Ageing and Senescence laboratory (www.rallislab.org) at Queen Mary University of London’s Cenfre for Molecular Cell Biology, reveals how caffeine—the world’s most popular neuroactive compound—might do more than just wake you up. The study in the journal Microbial Cell shows how caffeine could play a role in slowing down the ageing process at a cellular level.
Caffeine has long been linked to potential health benefits, including reduced risk of age-related diseases. But how it works inside our cells, and what exactly are its connections with nutrient and stress responsive gene and protein networks has remained a mystery—until now.
In new research published by scientists studying fission yeast—a single-celled organism surprisingly similar to human cells—researchers found that caffeine affects ageing by tapping into an ancient cellular energy system... (MORE - details, no ads)
