Our genome is organized into chromosomes, which are shaped like little X's. Every time a cell divides, the genome has to be replicated, and there are protective caps called telomeres on the ends of ...

Imagine your DNA as a set of shoelaces. Telomeres are like the plastic tips at the ends of those shoelaces, preventing them from fraying and unraveling. Structurally, telomeres are repetitive ...

A groundbreaking study has revealed that your mom and dad’s DNA don’t just pass on telomere length, they actively reshape it in the first days of life, influencing how we age and our risk of ...

Telo-seq -- a new tool -- is bringing telomere science into its modern era. Scientists can finally explore questions about the role of telomeres in aging and cancer that were not accessible with ...

Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from wear and tear. Similarly, chromosomes are capped by telomeres—specialized ...

A day in the life of DNA can be rough. It gets yanked across a dividing cell, zapped by radiation, and assaulted by chemicals. Luckily, cells have developed a complex set of repair mechanisms to ...

Tumors are stressful places for cancer-fighting immune cells. Low oxygen, high acid levels, and other stressors put strain on mitochondria, the cell’s energy factories, leading to T cell exhaustion ...

A research group from the National Cancer Research Center (CNIO) has found that an alteration in the POT1 gene prevents lung tissue from regenerating, which over time makes breathing difficult. The ...
