Another month passes, and more progress is made! As we kick off the beginning of summer, we have plenty of news to report regarding our upcoming conference and current campaign along with business news and the latest in rejuvenation research.


Summer is approaching, and we are happy to announce the fourth Ending Age-Related Diseases conference! On August 19-22, we will be meeting virtually to hear the latest developments from the leading experts in rejuvenation biotechnology research. During this four-day conference, you can exchange ideas with the best research teams working on the problem of aging, find new business partners, and spend time with like-minded people! Register today to take advantage of the Early Bird offer.

We thank our Platinum Sponsor NOVOS for fostering this scientific discussion on aging and rejuvenation!

PEARL Rapamycin CampaignWe have accomplished all the principal crowdfunding goals of the Participatory Evaluation (of) Aging (with) Rapamycin (for) Longevity Study, or PEARL, on Lifespan.io. The PEARL trial will be the first large-scale human trial with a focus on slowing down aging. Help us reach our stretch goals to make this campaign an even bigger success!


The PEARL team has also created an Ask Me Anything (AMA) thread on Reddit, where they answer users’ questions about this upcoming project.

Aging Begins After a Rejuvenation Event in Early Life: This month, we have one of the authors, Dr. Vadim Gladyshev, joining us, and he will be talking us through new research showing that aging does not begin as early as we thought in humans; instead, it follows a “rejuvenation event” during embryogenesis.
