The aging population has […]

In the 1970s, with the help of electron microscopy, scientists discovered that human RNA can also be circular. However, it was far from clear what this actually meant – and how it might be understood. And up to a few short years ago, it was widely assumed in scientific circles […]

The discovery of the UM171 molecule, by Dr. Guy Sauvageau and Anne Marinier, made headlines in 2014 following an article in Science. Hailed by some as a revolution, even a miracle, in the field of blood stem cell transplantation, the UM171 molecule is delivering on its promise. After the two-year clinical […]

With CAR T cell therapy, a patient’s own immune cells are genetically modified and inserted back into the body to find and kill cancer. This form of immunotherapy has already revolutionized some cancer treatments, but once the CAR T cells are inside a patient, where do they go? How do […]

Given the amount of wear and tear it’s subjected to on a daily basis, the skin has a phenomenal ability to replenish itself. Spread throughout it are small reservoirs of stem cells, nested within supportive microenvironments called niches, which keep a tight rein on this repair process. Too much tissue […]

Studying mice, scientists have shown that boosting the activity of specific immune cells in the heart after a heart attack can protect against developing heart failure, an invariably fatal condition. Patients with heart failure tire easily and become breathless from everyday activities because the heart muscle has lost the ability […]

As we age, our bodies tend to develop diseases such as heart failure, kidney failure and diabetes, and the presence of anyone disease increases the risk of developing others. A drug usually targets only one condition, largely ignoring the interconnectedness of age-related diseases and requiring patients to take multiple drugs, […]

Signs of frailty and the risks it brings could be identified in young and old people alike through a new assessment developed in a study by researchers at the Universities of Strathclyde, Manchester, Liverpool, Edinburgh, and Yale.
