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 ...

One protein appears to play an integral role in protecting telomeres, and possibly preventing cancerous growth, according to a study published this week in Science. Chromosomes with fluorescently ...

A new computational tool infers changes occurring at the ends of the chromosomes housing our DNA. It does so by detecting structural alterations in cells and tissues captured in images taken of ...

Much the way the caps on the ends of a shoelace prevent it from fraying, telomeres — regions of repetitive DNA sequences and a protein structure — protect the tips of chromosomes from damage. Every ...

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 Georgetown University professor is continuing novel research on the impact of DNA patterns on breast cancer. Zheng’s most recent research, published in September 2024, shows a new method of telomere ...

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 ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

When I last wrote about the research I did on aging and exercise, I focused on one of the major ways biologists can tell where a person is in the aging process: the epigenetic clock. I described a ...

Premature aging may be due to various factors, such as telomere shortening and a lack of cell division. Lifestyle habits such as eating a nutritious diet, being physically active, and getting enough ...
