Environmental pollutants could impact cellular signs of aging

Researchers have linked some environmental pollutants with diseases, a decreased life span and signs of premature aging, such as wrinkles and age spots. But can accelerated aging be detected at the cellular level in healthy ...

Traffic noise may make birds age faster

Traffic noise may be associated with an increased rate of telomere loss in Zebra finches that have left the nest, according to a study published in Frontiers in Zoology. Telomeres are caps on the ends of chromosomes that ...

City-dwelling blackbirds have poorer measures of health

Blackbirds live longer in cities than in forests. But their telomeres, repetitive stretches of DNA at the ends of the chromosomes, show that these city birds have a much poorer health status than their rural cousins. These ...

Young birds suffer in the city

City life is tough for young birds. But if they survive their first year, they are less susceptible to the effects of stress, according to research from Lund University in Sweden.

Early stress in starlings found to lead to faster aging

(Phys.org) —A combined team of researchers from Newcastle University and the University of Glasgow, both in the U.K. has found that stress in young starlings can lead to shortened telomeres—which prior research has suggested ...

Loneliness impacts DNA repair

Scientists at the Vetmeduni Vienna examined the telomere length of captive African grey parrots. They found that the telomere lengths of single parrots were shorter than those housed with a companion parrot, which supports ...
