Latest Ageing Stories
Research points to critical role of maternal health and well-being during pregnancyYoung adults whose mothers experienced psychological trauma during their pregnancies show signs of accelerated aging, a UC Irvine-led study found.The researchers discovered that this prenatal exposure to stress affected the development of chromosome regions that control cell aging processes. The study results, which appear online this week in the Proceedings of the National Academy of Sciences, point to the...
HOUSTON, July 21, 2011 /PRNewswire/ -- America's #1 rated morning news program, The Today Show, featured a story highlighting SpectraCell's Telomere Test, a blood test that measures cellular aging. The segment entitled How to Live to 100 showcased SpectraCell's Telomere Test as a tool for those interested in monitoring their health with biomarkers specific to longevity and aging. The Telomere Test measures a person's biological age in comparison to their chronological age, giving a person...
Telomeres, the body's own cellular clocks, may be a crucial factor underlying the development of emphysema, according to research from Johns Hopkins University."We found that in mice that have short telomeres, there was a significant increased risk of developing emphysema after exposure to cigarette smoke," said Mary Armanios, MD, assistant professor of oncology at the Johns Hopkins School of Medicine.The study appears online ahead of the print edition of the American Journal of...
Focus on the positiveWhether we choose to accept or fight it, the fact is that we will all age, but will we do so successfully? Aging successfully has been linked with the "positivity effect", a biased tendency towards and preference for positive, emotionally gratifying experiences. New research published in Biological Psychiatry now explains how and when this effect works in the brain.German neuroscientists studied this effect by using neuroimaging to evaluate brain engagement in...
Scientists at Johns Hopkins have provided more clues to one of the least understood phenomena in some cancers: why the "ends caps" of cellular DNA, called telomeres, lengthen instead of shorten.In a study published online June 30 in Science Express, the Johns Hopkins researchers say they have identified two genes that, when defective, may cause these telomere elongations.Telomeres contain repeated sequences of DNA that, in normal cells, shorten each time a cell divides. Without...
Scientists have discovered a drug they believe can reverse the effects of premature aging and could extend human life by over a decade. Rapamycin was created from a chemical found in the soil on Easter Island, which is one of the most remote places on Earth and 2,000 miles off the coast of Chile. The drug, which has been nicknamed the "forever young" drug, was used in experiments on children suffering from Hutchinson-Gilford Progeria Syndrome (HGPS). HGPS is a rare condition in...
PROVO, Utah, June 27, 2011 /PRNewswire/ -- Released today, The Aging Myth is an explosive new book by noted scientist and anti-aging researcher Joseph Chang, Ph.D. that reveals how new genetic discoveries are challenging traditional anti-aging philosophies and helping people live younger longer. In The Aging Myth, Dr. Chang uses a conversational and accessible style to dispel common myths about aging and explains some of the latest groundbreaking research in the field, including: Why he...
Two Baylor College of Medicine doctors have received support for their research from Alex's Lemonade Stand, a nonprofit group dedicated to fighting pediatric cancer.Dr. Jason Shohet, assistant professor of pediatrics "“ hematology/oncology and co-chair of Texas Children's Cancer Center's Neuroblastoma Program, received a two-year, $200,000 Innovation Award from the organization for his research on reprogramming neuroblastoma cancer stem cells. Innovation Awards are given by Alex's Lemonade...
(Ivanhoe Newswire) "“ Researchers have found new clues about aging, by identifying a new pathway that sets the clock for programmed aging in normal cells. The study focused on a toxic protein called progerin and its interaction with telomeres, which cap the ends of chromosomes. Telomeres wear away during cell division. When they degrade sufficiently, the cell stops dividing and dies.The researchers found that dysfunctional and short telomeres activate production of progerin, which is...
NEW YORK, June 8, 2011 /PRNewswire/ -- When expressed (turned on), the gene (hTERT) located on Chromosome number 5p15.33 activates the enzyme telomerase. Human cells can keep living and dividing indefinitely when telomerase is continually present; i.e. the cells become immortal. Telomerase Activation Sciences, Inc. (T.A. Sciences®) announces TA-65® can extend human cell life indefinitely. TA-65® is a single molecule telomerase activator that turns on the Immortality Gene under...
