Affectionate Moms with Depression May Epigenetically Buffer Their Child from Stress

Different environmental factors experienced by a child can undoubtedly impact their life in the long run. Whether they were born into poverty, lack access to education, or are surrounded by violence, these experiences have the ability to dramatically disrupt their lives if they’re without the right support system. But, could a mother’s exposure to stress … Continue reading Affectionate Moms with Depression May Epigenetically Buffer Their Child from Stress

Epigenetics Could Turn on an ‘Obesity Switch’

We know that a predisposition to become overweight is found in our genes. Now, we’re starting to learn that epigenetics also has a hand in determining whether a person will become fat or lean. New research is uncovering the possibility of an epigenetic switch that is, interestingly, either “on” or “off”. A group of researchers … Continue reading Epigenetics Could Turn on an ‘Obesity Switch’

Accurately Telling the Age of Human Tissues and Cells by DNA Methylation Clock

External signs of the human body’s age can be given by wrinkles and graying hair. However, these signs may not be accurate to tell the age of human tissues and cells that construct your body. Geneticist and biomathematician Steve Horvath at the University of California Los Angeles has developed a multi-tissue predictor of age that enables … Continue reading Accurately Telling the Age of Human Tissues and Cells by DNA Methylation Clock

Short-Term Sleep Loss Alters DNA Methylation of Clock Genes

Sleep is crucial to our well-being and helps in the process of learning and memory formation. Without proper sleep we can feel moody, irritable, and have difficulty solving problems. We can even be less creative when we don’t get enough sleep. Now, research published in the Journal of Clinical Endocrinology and Metabolism is showing us that just … Continue reading Short-Term Sleep Loss Alters DNA Methylation of Clock Genes

Certain Ethnic Groups May Epigenetically Age Slower

Scientists have been curious about whether race or ethnicity directly impact molecular markers of aging. Could people of certain race be more likely to age faster or slower? A group of researchers from UCLA conducted a study that was the first of its kind, demonstrating that Latinos actually age more slowly than other ethnic groups. … Continue reading Certain Ethnic Groups May Epigenetically Age Slower

Menopause and Insomnia Might Epigenetically Speed Up Aging

For years, scientists have disagreed on whether menopause causes aging or aging leads to menopause, giving rise to a “which came first” debate. New epigenetic research may help settle this long-standing disagreement, offering evidence that menopause might actually make a woman age faster. Two recent UCLA studies show that menopause and its common side effect … Continue reading Menopause and Insomnia Might Epigenetically Speed Up Aging

Epigenetic Clock Destines Some to Age Faster Regardless of Lifestyle

Certain people will age quicker and die sooner, even if they keep their body healthy, suggests a largescale analysis by UCLA scientists. Regardless of how well you take care of yourself, an accelerated internal epigenetic clock may lead to an earlier death for some. Researchers assessed data from over 13,000 individuals, measuring levels of DNA … Continue reading Epigenetic Clock Destines Some to Age Faster Regardless of Lifestyle

Inherited Epigenetic and Behavioral Consequences of Trauma Could be Reversed

It’s possible that the impact of traumatic experiences may be epigenetically inherited via molecular memory that is passed down through generations. Although still controversial, new research takes this concept a step further and demonstrates that traumatic behavior could be reversed when it would otherwise be inherited. A study, published in Neuropsychopharmacology, was conducted by researchers … Continue reading Inherited Epigenetic and Behavioral Consequences of Trauma Could be Reversed

Cuddling Can Leave Positive Epigenetic Traces on Your Baby’s DNA

You might be familiar with the popular epigenetic study that suggests when mother rats lick their pups, they leave epigenetic marks on their babies’ DNA. This, in turn, helps them grow up to be calm adults. On the other hand, pups who receive very little licking, grooming, or nursing from their moms tend to grow up … Continue reading Cuddling Can Leave Positive Epigenetic Traces on Your Baby’s DNA

Delivery by Cesaerian Section Linked to Epigenetic Changes in Infant’s Blood Stem Cells

The way a baby is delivered may epigenetically impact stem cells of the infant, according to a new study at Karolinska Institutet. Their findings could help scientists understand the differences between various modes of delivery, for example, why babies delivered via cesarean section are statistically more susceptible to immunological diseases. It’s still uncertain whether this … Continue reading Delivery by Cesaerian Section Linked to Epigenetic Changes in Infant’s Blood Stem Cells
