Researchers obtain the first mice born with hyper-long telomeres

A chance finding 10 years ago led to the creation by researchers of the Spanish National Cancer Research Centre (CNIO) of the first mice born with much longer telomeres than normal in their species. Telomeres shorten throughout ...

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 ...

Researchers find mechanism that regulates telomeres

The tips of chromosomes have structures called telomeres comparable to the plastic cover at the end of shoelaces. They work as a protective cap that prevents genetic material from unfolding and corroding. When telomeres do ...

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 ...

Researchers discover key mechanism of DNA replication

Researchers from Osaka University in Japan have uncovered a key control mechanism of DNA replication with potential implications for better understanding how cells maintain genetic information to prevent diseases or cancer.
