Have we finally found a way to slow down the ageing process? – Copyright Euronews/CanvaBy Camille Bello Despite centuries of research and progress in medicine, there are still many mysteries that remain unresolved, chief among them being an understanding of what causes ageing and how can we slow it down or reverse it. But a new study...

Researchers have discovered how genetic mutations accumulated slowly over a lifetime lead to dramatic changes in how blood is formed after the age of 70, providing a new theory for ageing. New research has uncovered how genetic changes that accumulate slowly in blood stem cells throughout life are likely to be responsible for the dramatic...
by University of Portsmouth Credit: CC0 Public Domain Those hoping to avoid one of the worst side effects of aging—bone, joint and muscle pain that doesn’t go away—might need to exercise a lot harder and more often than previously believed. According to a new study, only high levels of activity at least once a week—playing...

Importantly this discovery has opened up the possibility of drugs to promote this enzyme’s activity, protecting against the consequences of aging on metabolic health, including...
by University of Exeter Credit: Unsplash/CC0 Public Domain Poor sleep in the over 50s is linked to more negative perceptions of aging, which in turn can impact physical, mental and cognitive health, new research has revealed. A study led by the University of Exeter and found that people who rated their sleep the worst also felt...
A little over a decade ago, a clutch of scientific studies was published that seemed to show that survivors of atrocities or disasters such as the Holocaust and the Dutch famine of 1944-45 had passed on the biological scars of those traumatic experiences to their children. The studies caused a sensation, earning their own BBC Horizon documentary and the cover...

Sophia Antipolis, France – 23 Aug 2021: Drinking alcohol during adolescence to young adulthood is associated with accelerated arterial stiffening, a precursor to cardiovascular disease. That’s the finding of a study presented at ESC Congress 2021.1 “There was some evidence of a graded increase with heavier usage, meaning that the more you drink, the greater the...
A study led by researchers at WIMR has, for the first time, demonstrated how CD47 – a cell surface protein – drives biological dysfunctions in the body, such as decreased circulation and poor metabolic homeostasis, both of which worsen with age. Researchers hope developing therapies that target CD47 will significantly reduce the impact these health issues have on older...
