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 ...

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 ...

How worrying about getting old is making you age faster - IN FOCUS: As new research suggests that anxiety about the future is taking its toll on us biologically, Helen digs into the science behind thi ...

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 ...

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 ...

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 ...

A study published in Ecological and Evolutionary Physiology reveals a surprising link between cellular aging markers and ...
