Hematopoietic stem cells in the bone marrow age differently in genetically identical mice

Our bone marrow - the fatty, jelly-like substance inside our bones - is an unseen powerhouse quietly producing 500 billion new blood cells every day.

How random gene activity shapes lifespan in C. elegans

Why do some people live for longer than others? The genes in our DNA sequence are important, helping avoid disease or maintain general health, but differences in our genome sequence alone explain less than 30% of the natural variance of human life expectancy.

Restoring youthful TERT levels reverses aging phenotypes in preclinical models

Researchers at The University of Texas MD Anderson Cancer Center have demonstrated that therapeutically restoring 'youthful' levels of a specific subunit of the telomerase enzyme can significantly reduce the signs and symptoms of aging in preclinical models.

Advances in organoids and embryonic models pose no risk to personhood, expert argues

Advances in organoids and embryonic models of human development have the potential to prompt social and existential questions - e.g., what defines human individuality? However, bioethicist Insoo Hyun of Harvard Medical School and the Museum of Science in Boston says that these models have the potential to strengthen rather than weaken the concept of human individuality when considered within the philosophical frameworks of "personhood" and sentience.

Researchers propose a 'protein aggregation clock' to measure aging and health

Could measuring protein clumps in our cells be a new way to find out our risk of getting age-related diseases? Professor Dorothee Dormann and Professor Edward Lemke of Johannes Gutenberg University Mainz (JGU), who are also adjunct directors at the Institute of Molecular Biology (IMB) in Mainz, propose the concept of a "protein aggregation clock" to measure ageing and health in a new perspective article published in Nature Cell Biology.

The hidden genetic switches influencing human height and bone health

In mammals, only 3% of the genome consists of coding genes which, when transcribed into proteins, ensure the biological functions of the organism and the in-utero development of future individuals. But genes do not function alone.

Synthetic cell mimics immune response via symmetry breaking

In a feat aimed at understanding how cells move and creating new ways to shuttle drugs through the body, scientists at Johns Hopkins Medicine say they have built a minimal synthetic cell that follows an external chemical cue and demonstrates a governing principle of biology called "symmetry breaking."

Enhancing CAR-T cell therapy with biodegradable scaffolds

CAR-T cell therapies are transforming the treatment of previously incurable blood cancers. Six approved CAR-T products have been administered to more than 20,000 people, and more than 500 clinical trials are underway.

UD researchers pioneer universal, economical method for proteomics sample preparation

Proteins are workhorses that carry out most of the biological functions in our cells. While the genes we inherit from our parents, our so-called genome, are fixed and usually remain unchanged throughout our lives, proteins in our bodies are constantly changing, as we age, under different health conditions and upon stimulation, such as with medical treatment.
