Children’s Chromosomes Age In Response To Social Deprivation And Neglect

Studies in institutionalized Romanian children have found that the length of time spent in conditions of social deprivation and neglect correlates with lower IQ and behavioral problems. A new study, led by researchers at Children’s Hospital Boston and Tulane University, shows that early adversity even affects children’s chromosomes – prematurely shortening the chromosome tips, known […]

Risk Of Accelerated Aging Seen In Patients With PTSD And Childhood Trauma

Adults with post-traumatic stress disorder (PTSD) and a history of childhood trauma had significantly shorter telomere length than those with PTSD but without childhood trauma in a study by researchers at the San Francisco VA Medical Center and the University of California, San Francisco. The results are published in the online Articles in Press section […]

DNA Decoded From Patients With Breast Cancer Reveals Complexity And Hints Toward Personalized Medicine

In the single largest cancer genomics investigation reported to date, scientists have sequenced the whole genomes of tumors from 50 breast cancer patients and compared them to the matched DNA of the same patients’ healthy cells. This comparison allowed researchers to find mutations that only occurred in the cancer cells. They uncovered incredible complexity in […]

Effects Of Stress And Pollution Passed To Future Generations Through Epigenetic DNA Changes

When the Human Genome Project ended a decade ago, scientists thought that they had closed the lid on all that is to be known about our genes. But what they really did was open a Pandora’s Box, says theoretical evolutionary biologist Prof. Eva Jablonka of Tel Aviv University’s Cohn Institute for the History and Philosophy […]

Scientists Identify A Key To Maintaining DNA Integrity And New Clues In Quest To Slow Aging

DNA contains all of the genetic instructions that make us who we are, and maintaining the integrity of our DNA over the course of a lifetime is a critical, yet complex part of the aging process. In an important, albeit early step forward, scientists have discovered how DNA maintenance is regulated, opening the door to […]

Gene Variants In Autism Linked To Brain Development

New research on the genomics of autism confirms that the genetic roots of the disorder are highly complicated, but that common biological themes underlie this complexity. In the current study, researchers have implicated several new candidate genes and genomic variants as contributors to autism, and conclude that many more remain to be discovered. While the […]

Endurance Exercise Prevents Premature Aging In Animals Genetically Engineered To Age Faster

Endurance exercise may stop you looking and feeling old, it may even help you live longer, a study by McMaster University researchers has found. The study, published today in the prestigious science journal Proceedings of the National Academy of Sciences (PNAS), found that premature aging in nearly every organ in the body was completely prevented […]
