Scientists take steps to unlock the secrets to the fountain of youth
ASU scientists, together with collaborators from the Chinese Academy of Sciences in Shanghai, have published today, in Nature Structural and Molecular Biology, a first of its kind atomic level look at the ...
Scientists identify first genetic variant linked to biological aging in humans
Scientists announced today they have identified for the first time definitive variants associated with biological ageing in humans. The team analyzed more than 500,000 genetic variations across the entire human genome to ...
How chromosome ends influence cellular aging
By studying processes that occur at the ends of chromosomes, a team of Heidelberg researchers has unravelled an important mechanism towards a better understanding of cellular aging. The scientists focused on the length of ...
New mouse model reveals a mystery of Duchenne muscular dystrophy
Children with Duchenne muscular dystrophy often die as young adults from heart and breathing complications. However, scientists have been puzzled for decades by the fact that laboratory mice bearing the same genetic mutation ...
Early stress in starlings found to lead to faster aging
Scientists open new window into how cancers override cellular growth controls
Rapidly dividing cancer cells are skilled at patching up damage that would stop normal cells in their tracks, including wear and tear of telomeres, the protective caps at the end of each chromosome.
Molecular VELCRO for chromosome stability
(Phys.org) —A team of scientists at the Friedrich Miescher Institute for Biomedical Research and the University of Geneva has functionally dissected the molecular processes that ensure the stability of ...
Do lazy mammals live longer?
Small furry mammals partial to a daily dose of hibernation in winter are probably extending their lifespan at the same time, according to a study published Wednesday.
Researchers show telomere lengths predict life expectancy in the wild
Researchers at the University of East Anglia have found that biological age and life expectancy can be predicted by measuring an individual's DNA.
It takes two to tangle: Scientists further unravel telomere biology
Chromosomes - long, linear DNA molecules – are capped at their ends with special DNA structures called telomeres and an assortment of proteins, which together act as a protective sheath. Telomeres are maintained through ...
Exercise may prevent stress on telomeres, a measure of cell health
UCSF scientists are reporting several studies showing that psychological stress leads to shorter telomeres the protective caps on the ends of chromosomes that are a measure of cell age and, thus, health. The findings ...
Social status has impact on overall health of mammals
High social status has its privileges—when it comes to aging—even in wild animals.
A new ending to an old 'tail'
In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists ...
Study finds link between chronic depression and accelerated immune cell aging
(PhysOrg.com) -- Certain cases of major depression are associated with premature aging of immune cells, which may make people more susceptible to other serious illness, according to findings from a new UCSF-led study.
