This month, a collaboration between NASA and various research institutions pinpointed a “central biological hub” that controls health during space travel. The culprit is the cell’s energy factory, the mitochondria, which breaks down in function in a way eerily similar to aging. Like shutting down power and water in a city, disruptions to the mitochondria reverberate throughout the cells and organs, potentially leading to problems with sleeping, the immune system, and more in space. The results were [published in *Cell](https://www.cell.com/cell/fulltext/S0092-8674(20)31461-6).*

Dr. James Weinstein, is Senior Vice President, Microsoft Healthcare, where he is in charge of leading strategy, innovation and health equity functions.
Prior to Microsoft, Dr. Weinstein was president and CEO of Dartmouth-Hitchcock Health, a $2.0 billion academic medical center in Northern New England, where he led the organization to adopt a population health model, including the transition from fee-for-service toward global payments.
Prior to becoming CEO, Dr. Weinstein served as president of Dartmouth-Hitchcock Clinic and was director of The Dartmouth Institute for Health Policy and Clinical Practice (TDI), home of the Dartmouth Atlas of Health Care, which for decades has documented the ongoing variations in health care delivery across the United States.
Dr. Weinstein is a founding member and the inaugural executive director of the National High Value Healthcare Collaborative, along with Mayo Clinic, Intermountain Healthcare, The Dartmouth Institute, and Denver Health. The Collaborative is a partnership of health systems that has taken on the challenge of improving the quality of care while lowering costs on a national scale.
If you want to live long enough to see a reversal of aging and everlasting youth, exercise should be at the core of your routine.
Here I look at ten amazing benefits that exercise brings to your body and mind, so if you haven’t already got a regime on the go, hopefully this will convince you to start now.
Have an amazing day 🙂
In Why We Should Exercise Regularly, I show ten great areas that exercise benefits the body and mind.
If you want tp live longer and healthier, and slow down aging then regular exercise should be your first thought, especially if you have a sedentary job and have to spend long hours sat down.

Dr. Carolina Reis Oliveria, is the CEO and Co-Founder of OneSkin Technologies, a biotechnology platform dedicated to exploring longevity science.
Carolina holds her Ph.D. in Immunology at the Federal University of Minas Gerais, in collaboration with the Rutgers University, where she conducted research with pluripotent stem cells as a source of retinal pigmented epithelium (RPE) cells, as well as the potential of RPE-stem cells derived as toxicological models for screening of new drugs with intra-ocular applications.
She founded a company called CELLSEQ solutions in Brazil which develops tools to revolutionize the safety and toxicology assays performed by pharmaceutical, cosmetic, agro-chemical and food industries, with technology based on stem cells and big data analysis.
She is an alumnus of IndieBio, the world’s leading biotechnology accelerator.
In 2016, Carolina relocated to Silicon Valley from Latin America to co-found OneSkin, and to lead the development of the company’s technologies.

Despite early failures in the clinic, the idea of anti-aging therapies that purge the body of dying cells is gaining traction with a raft of startups now focused on senescence.
Brain on a chip for drug discovery.
Since the advent of organ-on-a-chip, many researchers have tried to mimic the physiology of human tissue on an engineered platform. In the case of brain tissue, structural connections and cell–cell interactions are important factors for brain function. The recent development of brain-on-a-chip is an effort to mimic those structural and functional aspects of brain tissue within a miniaturized engineered platform. From this perspective, we provide an overview of trace of brain-on-a-chip development, especially in terms of complexity and high-content/high-throughput screening capabilities, and future perspectives on more in vivo-like brain-on-a-chip development.
With the advent of an aging society, the disease incidence rate is increasing, and the cost of drug development and disease treatment is expanding exponentially.1,2 According to the World Health Organization (WHO), nearly one billion people in the world suffer from neurodegenerative diseases such as Alzheimer’s (AD) and Parkinson’s diseases.3 Despite decades of research on neurodegenerative diseases by many biologists and pharmaceutical companies, the underlying mechanism of their onset and progression is still largely unknown. The resolution of these diseases has a long way to go, and such steps are limited due to the lack of a suitable in vitro model system for mechanism study and drug development. In particular, the complex tissue structures and cell–cell interactions of the in vivo system make it challenging to unravel the underlying mechanism of the diseases and to predict the efficacy of clinical medicine.

The exact gene that caused stem cell aging has been identified.
Above – When mesenchymal stem/stromal cells (MSCs) age, the transcription factor GATA6 is increasingly produced in the cell to induce aging response. By transcription factor-based cellular reprogramming, aged MSCs are rejuvenated with a reduction in GATA6 effects on cellular aging. CREDIT AlphaMed Press
University of Wisconsin-Madison researchers found that the expression of GATA6, a protein that plays an important role in gut, lung and heart development, was repressed in the reprogrammed cells compared to the control cells. This repression led to an increase in the activity of a protein essential to embryonic development called sonic hedgehog (SHH) as well as the expression level of yet another protein, FOXP1, necessary for proper development of the brain, heart and lung. “Thus, we identified the GATA6/SHH/FOXP1 pathway as a key mechanism that regulates MSC aging and rejuvenation,” Dr. Li said.
Part of my series to give a good grounding in the basics surrounding the subject of human health and longevity, for anyone interested, this week it is Sirtuins.
Are they one of the keys to the door towards ending aging?
I give a basic explanation of what sirtuins are and how they are being investigated for their influence on health span and length of life.

Imagine, for a moment, that time travel is real.
Harvard Medical School scientists report they have successfully restored vision in mice by turning back the clock on aged eye cells in the retina to recapture youthful gene function.
The team’s work, described Dec. 2 in the publication Nature, represents the first demonstration that it may be possible to safely reprogram complex tissues, such as the nerve cells of the eye, to an earlier age.
In addition to resetting the cells’ aging clock, the researchers successfully reversed vision loss in animals with a condition mimicking human glaucoma, a leading cause of blindness around the world.
