Researchers at the School of Molecular Sciences at Arizona State University have discovered a potential way to supercharge our stem cells and reverse some aspects of cellular aging.

The Hayflick limit

Normal cells cannot divide indefinitely; they have a built-in replicative limit, which is often called the Hayflick limit after its discoverer, Leonard Hayflick. This Hayflick limit means that regular human cells are unable to replicate forever; once they reach their replicative limit, they cease to divide and enter senescence, a nondividing state in which the cell destroys itself.

Speaking a second language slows brain aging and makes you smarter.

Scientists have been rejuvenating old mice with infusions of not just the blood of younger mice, but even blood from teenage human beings — and we finally have our first clues on why this strange technique works.

Researchers have discovered an enzyme that helps rescue ageing brains from cognitive decline. So far it’s only been shown in mice, but if the same mechanisms are found in humans, it could lead to a new class of anti-ageing therapies.

Four years ago, a team of researchers led by neurobiologist Saul Villeda from the University of California, San Francisco, discovered that giving older mice infusions of blood from younger mice improved their memory and learning by improving connections in the hippocampus.

The NASA/ESA Hubble Space Telescope caught sight of a soft, diffuse-looking galaxy that is probably the aftermath of a long-ago galactic collision. Two spiral galaxies, each perhaps much like the Milky Way, swirled together for millions of years.

In such mergers, the original galaxies are often stretched and pulled apart as they wrap around a common center of gravity. After a few back-and-forths, this starry tempest settles down into a new, round object. The now subdued celestial body, cataloged as SDSS J162702.56+432833.9, is technically known as an elliptical galaxy.

When galaxies collide—a common event in the universe—a fresh burst of star formation typically takes place as gas clouds mash together. At this point, the galaxy has a blue hue, but the color does not mean it is cold: it is a result of the intense heat of newly formed blue–white stars. Those stars do not last long, and after a few billion years the reddish hues of aging, smaller stars dominate an elliptical galaxy’s spectrum. Hubble has helped astronomers learn of this sequence by observing galaxy mergers at all stages of the process.

Harvard University’s David Sinclair, world renowned for his anti-aging research, sees no limit on human life span and is collaborating on a clinical trial to evaluate the effectiveness of a new drug aimed at slowing the aging process…

“There is no maximum human life span,” says Sinclair, Ph.D., who is a professor in the Department of Genetics and co-director of the Paul F. Glenn Center for the Biology of Aging at Harvard Medical School. “Anyone who says that doesn’t know what they are talking about.”

Sinclair hopes to demonstrate what he has been researching, – and talking about, for the past 20 years – that aging is a disease, which can be treated.

Summary: A new study didn’t find much of a difference between healthy low-carb and low-fat diets. The people on both diets lost about the same amount of excess weight. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Is cutting carbs or cutting fat is better? A new study published in the Journal of the American Medical Association, suggest that it may not matter much.

A team of researchers led by Christopher Gardner, a professor of medicine at the Stanford University School of Medicine, followed 609 overweight adults ages 18 to 50. The researchers put the study participants, consisting of equal numbers of men and women, on either a low-carb diet or low-fat diet for 12 months.

Summary: UCSF scientists discover a protein in young blood that rejuvenates an aging brain. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Scientists have long been searching for the factors in young blood that give it its rejuvenating powers to drug form for widespread public use.

A team of researchers led by Saul Villeda, Ph.D., an assistant professor of anatomy at UC San Francisco discovered a brain-rejuvenating enzyme that improved memory in adult mice when restored to youthful levels. The researchers say the new protein could lead to new therapies for maintaining the healthy brain function of humans.
