Credit: Salk Institute Scientists at the Salk Institute have debuted a new method for determining both the length and sequence of telomeres on individual chromosomes. Their breakthrough anti-aging and cancer telomere tech …
Exercise is called a drug-free polypill that can benefit nearly everyone by many physicians because it can help prevent and treat many chronic diseases at a low cost that are associated with aging. More to it, exercise-induced changes reprogram the epigenetic expression of fibers to a more youthful state. So, to answer the question “Can …
New research identifies a larger pool of genes involved in clonal haematopoiesis than previously thought, and their implications for disease and diagnostic tests. Scientists have discovered 17 additional genes that drive the abnormal overgrowth of mutated blood cells as we age. The findings, published in Nature Genetics, provide a more complete view of the genetic …
Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from the chronological age that is calculated using the date of birth. The precision of these aging clocks suggests that the aging process follows a programme. Scientists David …
Nothing lives forever, but compared to other cells in the body, hematopoietic stem cells (HSCs) are remarkably long-lived. HSCs are blood-forming cells — they give rise to rapidly dividing progenitor cells, which in turn generate hundreds of billions of cells to fulfill the daily demand of oxygen-delivering red blood cells, disease-fighting white blood cells and …
At a Glance: Researchers found that depleting certain stem cells improved the immune systems of aged mice. The findings suggest that a similar treatment might be used to help protect older people against infections. The risk for serious infections rises with age, as people’s immune systems lose the ability to respond to novel infections. Part …
Certain RNA molecules in the nerve cells in the brain last a lifetime without being renewed. Neuroscientists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now demonstrated that this is the case together with researchers from Germany, Austria, and the USA. RNAs are generally short-lived molecules that are constantly reconstructed to adjust to environmental conditions. With their findings …
Whenever we cut ourselves stem cells rush to the rescue, growing new epidermis to cover the wound. But only some of these stem cells are normally dedicated to replenishing the epidermis that ultimately protects our body. Other stem cells are former hair follicle stem cells that usually promote hair growth but will also respond to …
Researchers at the Vienna University of Technology have made strides towards creating replacement tissue using a technique that differs from other methods currently being used around the world. The paper, “Scaffolded spheroids as building blocks for bottom-up cartilage tissue engineering show enhanced bioassembly dynamics,” published in Acta Biomaterialia describes their new approach. The team used …
An international team has shown that the injection of a type of stem cell into the brains of patients living with progressive multiple sclerosis (MS) is safe, well tolerated and has a long-lasting effect that appears to protect the brain from further damage. The study, led by scientists at the University of Cambridge, University of …
