This month, there’s been plenty of exciting news in the world of research and development, and there’s good news about our recently completed crowdfunding campaign and upcoming conference. Here’s what’s happened in the month of June.

LEAF News

Ending Age-Related Diseases Conference 2021Join Us for the Ending Age-Related Diseases Conference!: August 19-22 sees the arrival of the annual Ending Age-Related Diseases conference, where we will discuss progress in the development of diagnostics for aging along with drugs and therapies for healthy life extension. The conference will be virtual this year due to the current global pandemic, which means you can join us from the comfort of home.

Every year, we bring you an amazing selection of the best speakers from our industry, and this year will feature Eric Verdin (The Buck Institute for Research on Aging), Aubrey de Grey (SENS Research Foundation), Joao Pedro de Magalhaes (University of Liverpool), Irina Conboy (UC Berkeley), Jacob Kimmel (Calico), Michael Snyder (Stanford University School of Medicine), Lorna Harries (Senisca), Steve Horvath (UCLA), and many other aging researchers.

PEARL Is Funded, Rapamycin Longevity Clinical Trials Begin: Today is a doubly important day: it marks the final day of the PEARL campaign and it is a celebration of another victory for the life extension community. PEARL smashed its initial fundraising goal and sailed through its two stretch goals, raising just under $183k thanks to the generous support of the community.

The PEARL trial is now accepting participants for enrollment! If you wish to learn more about this upcoming trial, visit the PEARL website. If you want to be part of the PEARL trial, get started by filling out the application form.

Zalzala interviewDr. Zalzala: PEARL Trial Could Advance the Longevity Field: Dr. Zalzala, one of the leading researchers of the upcoming PEARL trial, answers questions about what it is and what it intends to accomplish.

Party for Health Research Announces Election Year Fundraising Campaign: The German Party for Health Research is engaging in a fundraiser to get on the ballot for the upcoming election on September 26. This party believes that 10% of the German budget should be invested in the development of interventions against age-related diseases.

SENS is hiring! SENS Research Foundation is hiring for the following positions: Research Assistant, Postdoctoral Fellow, and a Research Lab Manager. For more information about the requirements for each position and how to apply, please visit https://www.sens.org/get-involved/work-with-us/

Journal Club

Exploring How Rapamycin Improves How Our DNA Is Stored: This month, Journal Club takes a look at rapamycin, a drug that has long been believed to slow down aging, and how it changes the way DNA is stored inside cells to support gut health and longevity.

LifeXtenShow

X10 Overpopulation TechOverpopulation and Near-Future Tech: Nicola describes how, even if longevity does lead to a global rise in population, near-future technologies may support this growing population.

Critiquing the Hallmarks of Aging: LifeXtenShow and the Sheekey Science Show collaborate to explain a recent critique of the Hallmarks of Aging, which holds that it lacks explanatory power and has unspoken assumptions.

Fewer Births or More DeathsFewer Births or More Deaths?: In the final episode of X10’s overpopulation series, Nicola discusses why it would be enormously unethical to stop the progress of life extension to hope to stop overpopulation.

Your Real Age: Your chronological age might not match your biological age according to your epigenetics; you might be physically older or younger than your date of birth says you are.

X10 An Ageless WorldA World Without Aging: On this episode, we discuss how the demographics and population of a world in which age-related diseases simply didn’t exist and what effects that would have on our planet.

Lifespan News

Lifespan News AlcoholismAlcoholism and Aging: A new study involving alcohol intake and aging, a twin study that shows that diet and exercise lower biological age, and the effects of sauna use on health and longevity.

COVID and Inflammation: The COVID-19 spike protein and inflammation, a NASA challenge for engineering human tissue, and the complete sequencing of the human genome.

LSN Cancer DetectionMultiple Cancer Detection: A test for multiple types of cancer, restricting blood flow in the brains of mice looks like brain aging, and a new, safer method of cellular reprogramming developed by Calico scientists.

Lifespan Docs

300 Years of Saving Animals, a Wildlife Guardian’s Wish: Simon Cowell, the CEO and founder of the Wildlife Aid Foundation (WAF), does not want aging to impede his valuable work in this new Lifespan Docs episode by Tim Maupin.

Rejuvenation Roundup Podcast

Ryan O’Shea of Future Grind hosts this month’s podcast, showcasing the events and research discussed here.

Advocacy and Analysis

Saunas can activate heat shock proteins and may be a potential way to improve health and potentially, longevity.Saunas for a Personal Health and Longevity Strategy: High temperature causes stress to the body, which triggers a thermoregulatory response that seeks to restore homeostasis.

Life Extension – Humanity or Individuals First?: Preserving individual lives automatically preserves the human species because the species only exists as long as there are humans.

Death ClockThe “Death is Inevitable, Why Bother?” Argument: The questions “Why rejuvenate your body if it’s going to die anyway one day?” and “Why clean your house if it’s going to crumble to dust one day?” are similar.

Who Wants to Live Forever?: A recent survey of adults in the US found that only about one-third would take a life extension pill if one were available.

Developing healthy practices could help you live a longer life.Starting Your Personal Longevity Strategy: It is estimated that a relatively complete system of controlling biological aging is at least 20 years away, so your goal should be to live at least that much longer. What can be done to extend a healthy life today?

Evolution Won’t Stop Aging Any Time Soon, but Medicine Might: A new study about the ‘invariant rate of ageing’ has led to reports that aging is unstoppable and that we cannot cheat death. This is based on a misunderstanding of what the study actually says.

Education

This month, we have created four useful and informative articles on supplements and what they do. While we do not endorse any specific supplement, many of our readers are very interested in studies that show their effects.

Chamomile is a great source of Apigenin.Apigenin: This common flavonoid has been used in folk medicines for centuries as a way to treat anxiety and inflammation.

Fisetin: Commonly found in strawberries, this flavonoid is known to have antioxidant properties and demonstrates the specific biological activity of protecting functional macromolecules against stress

Creatine helps to build muscle and may slow down aging.Creatine: This widely known supplement has enjoyed great popularity as a supplement with athletes and bodybuilders in order to gain muscle, boost strength and increase exercise performance.

Pterostilbene: Studies have demonstrated that this polyphenol has antioxidant and anticarcinogenic effects.

Events

Astaxanthin supplementation enhances metabolic adaptation with aerobic training in the elderly: AX supplementation increased the preference for fat oxidation, increased exercise efficiency, and reduced carbohydrate oxidation, primarily in older males.

Higher diet quality relates to decelerated epigenetic aging: Higher diet quality is associated with slower epigenetic age acceleration, which partially explains the beneficial effect of diet quality on the lifespan.

Apigenin restores endothelial function in aging: Murine and in vitro experiments have shown that apigenin aids the arteries in multiple ways, including elasticity, foam cells, and reduced inflammation.

Systemic GLP-1R agonist treatment reverses mouse glial and neurovascular cell transcriptomic aging signatures: Exenatide treatment partially reverses age-related transcriptomic changes in brain endothelial cells.
