Researchers have mapped how "histone bivalency" acts as a molecular clock for brain development. By holding genes in a poised state, this mechanism ensures neurons mature only after completing ...

Perhaps best known as a immune-system boost or antidote to scurvy, vitamin C has been found to rejuvenate aging skin by reactivating genes responsible for cell growth. By promoting DNA demethylation, ...

Researchers at the CU Anschutz Cancer Center have discovered how breast cancer cells that spread to the lungs may take ...

Using a variety of laboratory and animal models, the team found that cysteine fuels the production of the antioxidant ...

A newly developed synthetic cell matrix could provide a surface on which to culture and differentiate billions of delicate stem cells for medical uses. For decades, scientists have been exploring ...

The beta cells in the pancreas act as highly sensitive sensors that constantly measure the amount of sugar in our blood. As soon as we eat something and the sugar level rises, the beta cells produce ...

Hyperspectral imaging has provided an insight into how cells organize and prioritize organelle growth. As cells grow, their organelles also need to grow. But do all the organelles grow at the same ...

When cancer cells begin to die within tumors, they expose signals on their surface that indicate they are dying. Macrophages then detect these signals and engage in phagocytosis, where they eat the ...

The interaction between growth and the active migration of cells plays a crucial role in the spatial mixing of growing cell colonies. This connection was discovered by scientists from the Department ...

Thinning hair has always been a symptom of aging, but experts say men seem to be losing their hair earlier than previous generations. Modern lifestyles may quicken hair loss due to increased stress, ...
