Time feels like it flies by or drags on depending on the intensity of your experiences. So, does that mean aging is merely a mindset?

Regenerative medicine: Revolutionising osteoarthritis treatment
Dr Torbjörn Ogéus is a pain specialist with clinical experience in regenerative medicine. He has been treating tendons and osteoarthritis (OA) with growth factors for 15 years. 6 years ago, Ogéus did his first stem cell treatment for OA and recently published one of the first clinical studies in the world on exosomes and OA.
Spatial Transcriptomic Clocks Reveal Local Cellular Interactions Influence Brain Aging
Certain cells in the brain create a nurturing environment, enhancing the health and resilience of their neighbors, while others promote stress and damage. Using spatial transcriptomics and AI, researchers at Stanford’s Knight Initiative for Brain Resilience discovered these interactions playing out across the lifespan—suggesting local cellular interactions may significantly influence brain aging and resilience.
A new study was published in Nature in an article titled, “Spatial transcriptomic clocks reveal cell proximity effects in brain aging.”
“What was exciting to us was finding that some cells have a pro-aging effect on neighboring cells while others appear to have a rejuvenating effect on their neighbors,” said Anne Brunet, the Michele and Timothy Barakett Endowed Professor in Stanford’s department of genetics and co-senior investigator of the new study.

AI-powered algorithm enables personalized age transformation for human faces
Researchers at University of North Carolina at Chapel Hill and University of Maryland recently developed MyTimeMachine (MyTM), a new AI-powered method for personalized age transformation that can make human faces in images or videos appear younger or older, accounting for subjective factors influencing aging.
This algorithm, introduced in a paper posted to the arXiv preprint server, could be used to broaden or enhance the features of consumer-facing picture-editing platforms, but could also be a valuable tool for the film, TV and entertainment industries.
“Virtual aging techniques are widely used in visual effects (VFX) in movies, but they require good prosthetics and makeup, often tiresome and inconvenient for actors to wear regularly during shooting,” Roni Sengupta, the researcher who supervised the study, told Tech Xplore.
ARPA-H launches new program aimed at extending the healthspan of Americans
The Advanced Research Projects Agency for Health (ARPA-H), an agency within the U.S. Department of Health and Human Services (HHS) announced a new funding opportunity through the launch of the PROactive Solutions for Prolonging Resilience, or PROSPR, program. The big question that drives the program is, “What if we had therapies to extend healthspan and prevent the onset of age-related diseases?”
ARPA-H PROSPR Program Manager Andrew Brack, Ph.D., says, “the ultimate goal is to extend healthspan—meaning the number of years aging adults live healthy lives and enjoy overall well-being by compressing the frailty and disability that comes with aging, into a shorter duration of time near the end of life.” The PROSPR program builds on foundational work by the National Institute of Aging and will work with industry and regulators to accelerate the testing and availability of new therapeutics targeted at healthspan.
This commitment by ARPA-H is not only an investment in national health, but an impactful economic investment. The number of people 65 and older accounts for 18% of the U.S. population and is projected to increase to 23% by 2054. Considering their increased care needs relative to younger ages, health care costs will increase by 75% if nothing is done to prevent the progressive loss of physical functioning during aging, according to a Pew Research Center Study. It is estimated that increasing the average American healthspan would lessen health care costs due to a combination of fewer medical needs, less reliance on assistance by others, and increased potential for individuals and their family caregivers to remain in the workforce. Because of these and other factors, it is estimated that extending healthspan by one year in only 10 percent of the aging population would reduce costs of U.S.
