Dr. Jekyll & Mr. Hyde: Telomere and telomerase in stem cells

When a human cell divides, its daughter cells should each receive an identical copy of the mother cell's genome. Occasionally mistakes occur during this process, generating mutations that can give rise to cancer. To avoid ...

Role of telomeres in plant stem cells discovered

The role played by telomeres in mammalian cells has been known for several years. It is also known that these non-coding DNA sequences, which are found at the ends of the chromosomes, protect them and are necessary to ensure ...

How fast you age depends on your parents

In the hunt for better knowledge on the aging process, researchers from Lund University have now enlisted the help of small birds. A new study investigates various factors which affect whether chicks are born with long or ...
