Every single cell in your body ticks to the rhythm of its own internal clock – even cancerous ones. Timing chemotherapy with these 24-hour (ish) circadian cycles could significantly improve treatments ...

Researchers use epigenetic clock, DNA methylation and mouse model to demonstrate that T cell proliferation can stretch past organism lifespan and acuta lymphoblastic leukemia T cells appear hundreds ...

St. Jude co-corresponding authors Caitlin Zebley, MD, PhD, Department of Bone Marrow Transplantation & Cellular Therapy and Ben Youngblood, PhD, Department of Immunology, used an epigenetic clock to ...

What if there was a way to make aging brain cells younger again? An international research team from Spain and Luxembourg recently set out to address this question. After developing an aging clock ...

Scientists from the Chinese Academy of Sciences and Monash University report that they have developed a new method to measure biological aging in individual cell types. The new tool offers a more ...

The daily rhythm of genetic activity varies between individual cell types in ways that depend on their states of health, a recent study has found, revealing details on the relationship between ...

From fruit flies that survive a mere two weeks to the giant tortoises of the tropics that can live for nearly 200 years, every species has an allotted life expectancy. But while an organism’s lifespan ...

A research team has discovered when and why inflammatory signaling affects the formation of blood stem cells in embryos, which will benefit efforts to develop lab-grown, patient-derived stem cell ...

As we age, our immune system also ages. We become more susceptible to infections, vaccinations work less well and the risk of developing immune-related disorders such as autoimmune diseases increases.
