Surviving extreme conditions in nature is no easy feat. Many species of mammals rely on special adaptations called daily torpor and hibernation to endure periods of scarcity. These states of dormancy ...

Mouse data from a new study published Feb. 28 in Nature and sponsored in part by Chroma Medicine suggest that epigenetic gene silencing can suppress the target gene for nearly a year, providing new ...

Aging may "erase" the epigenetic markers that control gene expression in the brain, and this may snowball to cause unintended consequences, a new mouse study suggests. Tiny chemical messages attached ...

Among genetically identical "agouti viable yellow" (A vy) mice, some are brown and lean while others are yellow and obese. These differences are due to epigenetics, a system of molecular tags—such as ...

Endocrine resistance—a major cause of breast cancer deaths—can be underpinned by an epigenetic change called DNA methylation, researchers at the Garvan Institute of Medical Research have discovered.

In response to food deprivation or harsh environmental conditions, many mammalian species engage energy-conserving strategies, such as torpor and hibernation. Torpor is a state of profoundly decreased ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

When a new memory forms the brain undergoes physical and functional changes known collectively as a “memory trace.” This memory trace represents the specific patterns of neuronal activity and ...
