During the past few years a number of studies have been published showing that sitting for long periods of time may decrease lifespan and contribute to other health problems. Now new research has studied the opposite side of this. Instead of measuring only the negative effects of prolonged sitting the scientists measured the benefits of […]

It has been known for decades that caloric restriction significantly increases lifespan and health span in animals. Limiting food intake of mice, worms, and flies starting from birth lengthens their lifespan by 30% or more. Even more significant is that maximum lifespan increases not just the average. Of course there is no ethical or practical […]

The stem cells found within the average adult human are capable of restoring dying cells while also fixing damaged tissue. Nothing is safe from the aging process, though, and as we get older we begin to lose the very same stem cells that once kept our bodies in functional condition. But there could be a […]

While cognitive abilities naturally decline with age, eating one serving of leafy green vegetables a day may aid in preserving memory and thinking skills as a person grows older, according to a study by researchers at Rush University Medical Center in Chicago. The study results were published in the December 20, issue of Neurology, the […]

In remote Italian villages nestled between the Mediterranean Sea and mountains lives a group of several hundred citizens over the age of 90. Researchers at the University of Rome La Sapienza and University of California San Diego School of Medicine have identified common psychological traits in members of this group. The study, publishing in International […]

Cardiovascular diseases are a major cause of death worldwide, in part because the cells in our most vital organ do not get renewed. As opposed to blood, hair or skin cells that can renew themselves throughout life, our heart cells cease to divide shortly after birth, and there is very little renewal in adulthood. New […]

Back in 2007 scientists announced that they had created embryonic like stem cells from adult human skin cells. IPS cells (induced pluripotent stem cells) have been very valuable in research, however converting them into any type of cell that could be used for actual stem cell therapy is extremely complicated and far from becoming safe […]

A researcher at the School of Medicine and his colleagues have succeeded in isolating mouse lung stem cells, growing them in large volumes and incorporating them into injured lung tissue in mice. The work raises hopes for regenerative therapies that could heal currently intractable lung diseases. A study describing the research was published online Nov. […]

Engineered tissue containing human stem cells has allowed paraplegic rats to walk independently and regain sensory perception. The implanted rats also show some degree of healing in their spinal cords. The research, published in Frontiers in Neuroscience, demonstrates the great potential of stem cells undifferentiated cells that can develop into numerous different types of cells […]

A team led by Professor Lorna Harries, Professor of Molecular Genetics at the University of Exeter, has discovered a new way to rejuvenate inactive senescent cells. Within hours of treatment the older cells started to divide, and had longer telomeres the ‘caps’ on the chromosomes which shorten as we age. This discovery, funded by the […]
