Epigenetic drift underlies epigenetic clock signals, but…
A new research paper was published in Aging (listed by MEDLINE/PubMed as “Aging (Albany NY)” and “Aging-US” by Web of Science) Volume 16, Issue 2, entitled, “Epigenetic drift underlies epigenetic clock signals, but displays distinct responses to lifespan interventions, development, and cellular dedifferentiation.”
Could Epigenetic Age Acceleration, Not Actual Age, Better Predict How Well You Remember?
A study led by researchers at Stony Brook University shows that age acceleration, when one’s so-called biological clock runs quicker than one’s actual age, is linked to poorer memory and slower rates of processing information. The team measured biological “clocks” derived from the DNA of 142 adults aged 25-65 years old and had the participants complete daily cognitive tests on smartphones. Their findings, which imply that epigenetic age acceleration could be a better indicator of how well a person remembers information and how quickly they work with information, are detailed in the Journal of Gerontology: Biological Sciences.
Understanding Epigenetic Changes in Glial Cells May be Key to Combatting Brain Tumors
Gliomas are incurable brain tumors. Researchers are trying to unlock the mysteries of how they originate from normal cells, which may lead to better treatments.
Do Children Inherit Parents’ Stressful Experiences?
Scientists are discovering that a parent’s experiences can lead to changes in gene expression that are encoded in the sperm or egg and passed to offspring. In other words, there is a way in which offspring inherit the experiences of their parents. This is different than inheriting genes for brown or blue eyes. It’s more like inheriting genes that are switched on or off for the purpose of being better adapted to a particular environment.
UC Irvine to lead multi-institutional study of single-cell vulnerabilities to Alzheimer’s disease

Long Telomeres, the Endcaps on DNA, Not the Fountain of Youth Once Thought — Scientists May Now Know Why
In a study of 17 people from five families, Johns Hopkins Medicine researchers say they found that ultra-lengthy DNA endcaps called telomeres fail to provide the longevity presumed for such people. Instead, people with long telomeres tend to develop a range of benign and cancerous tumors, as well as the age-related blood condition clonal hematopoiesis.

Children’s Hospital Los Angeles Identifies Molecular Markers to Increase Precision in Treatment of Retinoblastoma
Retinoblastoma is a cancer of the eye that occurs in infants and toddlers and can lead to loss of vision, loss of one or both eyes, and even death. Unlike most tumors, these cannot be biopsied because of the risk of spreading cancer to the rest of the body. In 2017, Jesse Berry, MD, surgeon and ocular oncologist at Children’s Hospital Los Angeles, discovered that fluid removed from the eye during treatment of retinoblastoma contained tumor DNA and functioned as a liquid biopsy—providing information about the tumor and opening the door to earlier diagnosis and treatment.
