Understanding Why the Thymus Shrinks With Age
Posted by Steve Hill in categories: biotech/medical, life extension
Today, we are going to take a look at a new study in which scientists at the Walter and Eliza Hall Institute of Medical Research have recently identified a type of cell that appears to be implied in thymic involution—the shrinking of the thymus[1].
Thymic involution is somewhat of a mystery in biology, a phenomenon that isn’t fully understood that happens to everyone with age and is a driving cause of immunosenescence, the age-related decline in our immune systems’ ability to fight disease. This new study helps to shed light on why it happens.

A crowdfunding platform aims to solve the puzzle of aging
Posted by Steve Hill in categories: bioengineering, biotech/medical, government, life extension
Dr. Oliver Medvedik Vice President of LEAF appears in this new TED interview where he talks about aging research and the possibilities of future medicine.
Aging happens to all of us, but scientists still don’t know the mechanism behind it. We need to focus on finding an answer, says molecular biologist Oliver Medvedik.
If given the option, would you choose to live forever? Many of us would say “yes,” but with one major caveat: just as long we don’t age. In scientific terms, aging means “a progressive loss of fitness in an organism over time,” says molecular biologist and TED Fellow Oliver Medvedik. What causes this loss of fitness in humans is multifaceted, although scientists are exploring different theories including — and these are just a few of the many avenues of research — the deterioration of the health of our telomeres (the ends of our chromosomes), changes in cell mitochondria, inefficient clearance of damaged cell proteins, and the senescence of stem cells, leading to chronic inflammation and a depletion of stem cells.

Top Five Deadly Vitamins
Posted by Brady Hartman in categories: biotech/medical, life extension
A look back at the most popular health articles of 2017. Here is the report: “Top Five Deadly Vitamins”
Summary: High-dose vitamin and mineral supplements were once promoted as ways to prevent heart disease, aging, and cancer. To the contrary, recent research has shown that excessive vitamin and mineral consumption sometimes shortens life. Using evidence from scores of clinical trials we generate a list of five vitamin and mineral supplements that have been shown to be harmful to an otherwise healthy person when consumed in excess.

Obesity Found to Cause Lasting Damage to Hematopoietic Stem Cells
Posted by Steve Hill in categories: biotech/medical, life extension
You might think that being overweight may cause you health problems only until you finally shed those extra pounds, at which point everything will be fine again. It sounds reasonable, but it might be not so easy. According to a new study published in the Journal of Experimental Medicine on December 27, the negative effects of obesity might last even after that extra weight has been lost.
Yes, it appears that being overweight can have lasting consequences that persist long after the weight comes off. Damage to the hematopoietic stem cells can be caused by being overweight, making it all the more reason to try to maintain a healthy weight as part of your personal health and longevity strategy.

The Gut Microbiota Could Contribute to Sarcopenia
Posted by Steve Hill in categories: biotech/medical, life extension
We have all seen it, the age-related loss of muscle mass and increasing frailty that generally accompanies advancing age. Recently the World Health Organization classified this age-related muscle wastage as a disease and thus sarcopenia entered official usage to describe it. There are a number of potential causes of sarcopenia and new research suggests that there is a nutritional link between the microbiota and development of the condition.
What is Sarcopenia?
Sarcopenia is the condition that causes the familiar, age-related loss of muscle strength and mass in older people, and it leads to ever-increasing frailty. Frailty makes everyday tasks difficult, affects balance, and can lead to falls, which can be very dangerous for older people.
