We would like to remind you once again that on January 26-28, 2021, the third annual Longevity Therapeutics Summit will commence! This fully online event will feature more than a hundred leaders in the longevity industry, including researchers and biotech executives, and will discuss ways to target, reverse, and delay the onset of age-related diseases.

Longevity Dialogues – Featuring Dr. Aubrey de Grey, Dr. Nir Barzilai and Keith Comito: Mark Sackler hosts a discussion focused on how to get the government and the general public on board with the idea of targeting aging directly to prevent age-related diseases.

Media Circus Surrounds Hyperbaric Oxygen Study: The media hype surrounding the results is nothing like the reality of the actual research paper, and this is another example of how shoddy journalism harms our field.

Send in the senolytics: Unity might have failed with UBX0101, but many other companies intend to make their own attempts at senescent cell removal, and Unity is trying again as well.

The Extracellular Matrix Is Key to Heart Health: A new article sheds light on the differences between the extracellular matrix (ECM) of healthy people and people in end-stage heart failure.

C60 Does Not Improve Lifespan nor Healthspan: The findings of this study not only raise concerns about available C60 supplements, they also undermine the rationale for using them in the first place.

Researchers Use Lung Organoids to Study COVID: This highly impactful and timely research simultaneously makes major contributions to the field of lung regeneration and to our fight against the current global pandemic.

Aged Blood Makes Young Cells Old: Exposing young cells to aged blood causes their gene expression to become akin to aged cells.

Diluting Aged Blood Rejuvenates Old Brains: Aged blood can support rejuvenation if properly calibrated or, in this case, simply diluted.

Inflammation Decreases NAD+ During Aging: Researchers have discovered a link between senescent cells and the decline of NAD+ that occurs with aging.
