Physician training makes doctors' DNA to age six times faster than normal

In just a few short weeks, tens of thousands of newly minted doctors will start the most intense year of their training: the first year of residency, also called the intern year.

Oxidative stress acts directly on telomeres to hasten cellular aging, study reveals

The same sources thought to inflict oxidative stress on cells- pollution, diesel exhaust, smoking and obesity- also are associated with shorter telomeres, the protective tips on the ends of the chromosomal shoelace.

Study finds no major epigenetic differences between space astronaut and his earthbound twin brother

In a landmark study, a group of U.S. scientists from Johns Hopkins, Stanford University and other institutions has found no long-lasting, major differences between the epigenomes of astronaut Scott Kelly, who spent a year in space aboard the International Space Station, and his twin brother, Mark, who remained on Earth.

Maternal smoking and pre-eclampsia may affect fertility of offspring

Low levels of oxygen in the womb - which can be caused by smoking or conditions such as pre-eclampsia - may cause problems with fertility later in life, a study carried out in rats suggests.

People born with short telomeres found to have short-lived immune system cells

Scientists at Johns Hopkins say they have found that people born with abnormally short chromosome endcaps, or telomeres, have immune system cells that age and die prematurely.

Study shows how cooperative breeding could increase lifespan

Seychelles warblers live and breed in family groups on the tiny island of Cousin. In each group, a dominant female and male reproduce.

Study: Female birds have longer, healthier lifespan when they have help raising offspring

Female birds age more slowly and live longer when they have help raising their offspring, according to new research from the University of East Anglia.

Medical treatment for gestational diabetes could prevent long-term complications in children

Researchers at Cardiff University have found that women taking metformin and/or insulin during gestational diabetes could reduce the risk of long-term complications for their child.

Cellular recycling process may prevent cancer initiation, finds study

Just as plastic tips protect the ends of shoelaces and keep them from fraying when we tie them, molecular tips called telomeres protect the ends of chromosomes and keep them from fusing when cells continually divide and duplicate their DNA.

Researchers gain new insights into pediatric tumors

Peripheral nervous system tumors are one of the most common types of childhood tumors. While some of these tumors, known as neuroblastoma, disappear on their own without treatment, others will continue to grow even despite intensive treatment.

Biological aging caused by cancer treatments correlates with cognitive decline

Cancer treatments are suspected to accelerate certain aging processes in the body. A new study has found that indicators of such biological aging correlate with declines in cognitive function in women who had undergone breast cancer treatment several years earlier.

Meditation, music may change biomarkers of cellular aging and Alzheimer’s disease in older adults

A research team led by Dr. Kim Innes, a professor in the West Virginia University School of Public Health, has found that a simple meditation or music listening program may alter certain biomarkers of cellular aging and Alzheimer's Disease in older adults who are experiencing memory loss.

Researchers uncover secret of immortality mechanism in aggressive glioblastoma

UC San Francisco researchers have discovered how a mutation in a gene regulator called the TERT promoter -- the third most common mutation among all human cancers and the most common mutation in the deadly brain cancer glioblastoma -- confers "immortality" on tumor cells, enabling the unchecked cell division that powers their aggressive growth.

RUDN biochemists describe previously unknown mechanism of autoimmunity regulation

The ability of a human body to resist pathogenic factors is under control of immune cells, the most important of which are lymphocytes.

Short telomeres could be independent risk factor for age-related functional decline

Elderly people with short chromosome caps, or telomeres, are more likely to have difficulty performing daily activities such as carrying groceries, climbing stairs and walking, finds a new study of more than 1,200 people from five European countries.

Gene therapy with telomerase does not increase cancer risk, study shows

Negative results and findings in science are perhaps less newsworthy, but they are no less important. Particularly when, as in this case, they demonstrate that a possible new therapeutic pathway against idiopathic pulmonary fibrosis and other diseases associated to short telomeres is in fact safe.

Study: Healthy diet could help promote healthy cellular aging in women

Eating a diet that is rich in fruits, vegetables and whole grains and low in added sugar, sodium and processed meats could help promote healthy cellular aging in women, according to a new study published in the American Journal of Epidemiology.

Scientists uncover key control 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.

Study shows why women with multiple pregnancies tend to age quickly

Multiple pregnancies might make women's cells age more quickly, a new Northwestern University study suggests.

Blood telomeres can help predict risk of disease worsening or death in COPD patients

Some patients with COPD demonstrate signs of accelerated aging. In a new study published in the journal CHEST researchers report that measuring blood telomeres, a marker of aging of cells, can be used to predict future risk of the disease worsening or death.
