New Discovery: This Molecule Could Beat Rapamycin in Longevity

This podcast features Dr. Ben Blue, CEO of Ora Biomedical, discussing the company's innovative approach to longevity drug discovery. Ora was spun out of Dr. Matt Kaeberlein's lab at the University of Washington and uses an automated robotic system called the WormBot to conduct high-throughput lifespan experiments in C. elegans (roundworms). The platform allows them to test interventions at unprecedented scale, approximately 1,000 molecules per month with proper statistical replication, generating what is likely the largest quality database of longevity interventions ever assembled. The company's core philosophy challenges the field's narrow focus on well-known pathways and molecules, arguing that vast areas of chemical and combinatorial space remain unexplored.

The Million Molecule Challenge represents Ora's ambitious vision to test one million interventions for longevity effects, which they estimate would cost just $5 million and could revolutionize aging biology. Despite limited funding so far, with contributions from about 150 individuals, they've already made significant discoveries. Most notably, they've identified multiple molecules that extend lifespan more effectively than rapamycin, long considered the gold standard longevity intervention. One such molecule, Omipalisib (an mTOR inhibitor), now serves as their positive control in experiments, showing effects superior to rapamycin. Their screening has revealed lifespan extensions of up to 60% in worms, demonstrating the power of unbiased, large-scale screening over traditional target-based approaches.

Beyond pure longevity research, Ora is pursuing practical clinical applications through their radiation resistance program, developed in partnership with the U.S. Air Force and Space Force. They're testing whether longevity interventions can protect against radiation damage relevant for cancer radiotherapy patients, astronauts, and military personnel. Their preliminary data shows promising results, and they're expanding this resilience approach to other environmental stressors including neurotoxins, wound healing, and traumatic injury. This strategy provides potential FDA approval pathways through specific disease indications while ultimately advancing longevity medicine more broadly.

The discussion highlighted both the promise and challenges facing the longevity field. While Ora has proven that high-throughput screening can identify superior interventions, they struggle to secure the relatively modest funding needed to complete their ambitious screening program. The conversation touched on the limitations of current research approaches, including over-reliance on a few well-studied pathways, insufficient data for meaningful AI applications, and the field's premature narrowing around the hallmarks of aging. Despite these challenges, Ora’s work demonstrates that starting with in vivo lifespan data in whole organisms, rather than cell culture studies, may prove more predictive of effects in humans, potentially transforming how we discover and develop longevity therapeutics.
