Natural “Fasting” Molecule Exerts Anti-Aging Effects to Protect Vascular System
A molecule produced by the body during fasting or calorie restriction has anti-aging effects on the vascular system, which could reduce the occurrence and severity of human diseases related to blood vessels, such as cardiovascular disease, according to a study led by Georgia State University.
“As people become older, they are more susceptible to disease, like cancer, cardiovascular disease and Alzheimer’s disease,” said Dr. Ming-Hui Zou, senior author of the study. “Age is the most important so-called risk factor for human disease. How to actually delay aging is a major pathway to reducing the incidence and severity of human disease.

Scientists create new standard genome for heavily studied worm
A new Cornell University-led study finds that the genome for a widely researched worm, on which countless studies are based, was flawed. Now, a fresh genome sequence will set the record straight and improve the accuracy of future research.
When scientists study the genetics of an organism, they start with a standard genome sequenced from a single strain that serves as a baseline. It’s like a chess board in a chess game: every board is fundamentally the same.
One model organism that scientists use in research is a worm called Caenorhabditis elegans. The worm—the first multicellular eukaryote (animal, plant or fungus) to have its genome sequenced—is easy to grow and has simple biology with no bones, heart or circulatory system. At the same time, it shares many genes and molecular pathways with humans, making it a go-to model for studying gene function, drug treatments, aging and human diseases such as cancer and diabetes.

New Progress in Stem-Cell-Free Regenerative Medicine
Regenerative medicine and stem cells are often uttered within the same breath, for good reason.
In animal models, stem cells have reliably reversed brain damage from Parkinson’s disease, repaired severed spinal cords, or restored damaged tissue from diabetes, stroke, blood cancers, heart disease, or aging-related tissue damage. With the discovery of induced pluripotent stem cells (iPSCs), in which skin and other tissue can be reversed into a stem cell-like state, the cells have further been adapted into bio-ink for 3D printing brand new organs.
Yet stem cells are hard to procure, manufacture, and grow. And unless they’re made from the patient’s own cell supply—massively upping production costs—they’re at risk of immune rejection or turning cancerous inside their new hosts.

Study shows how diet can prevent a mid-life microbiome crisis and improve brain health
A number of physiological and psychological changes occur as we age, and many studies have shown that our gut microbiome also changes as we grow older. A fascinating new study is suggesting that a shift in gut bacteria in our middle-age could trigger a process that plays a role in cognitive decline in our later years. And diet may be the key to encouraging the growth of beneficial bacteria that benefit healthy brain aging.
