Israeli scientists have found a way to increase the life expectancy of mice by 23 percent, in groundbreaking research that they hope to replicate in humans who could then reach an average age of 120 years old.
The researchers boosted the life expectancy of 250 rodents by increasing the supply of SIRT6, a protein that normally wanes in the aging process, the Times of Israel reported.
In the peer-reviewed research published in the journal Nature Communications, the scientists also said the protein-enriched animals were less prone to cancer. The change in life expectancy is significant when you consider that an equivalent jump in human life expectancy would have us living on average until almost 120, Prof. Haim Cohen of Bar-Ilan University in Ramat Gan told the news outlet.

Washington, June 2 (IANS) The US National Institutes of Health (NIH) has started a Phase 1/2 clinical trial in which adult volunteers who have been fully vaccinated against Covid-19 will receive booster doses of different Covid-19 vaccines to determine the safety and immunogenicity of mixed boosted regimens.

US starts clinical trial to evaluate safety of Covid booster shots Thursday, June 3, 2021 IWK Bureau
The US National Institutes of Health (NIH) has started a Phase 1/2 clinical trial in which adult volunteers who have been fully vaccinated against Covid-19 will receive booster doses of different Covid-19 vaccines to determine the safety and immunogenicity of mixed boosted regimens. Although the vaccines currently authorised by the US Food and Drug Administration offer strong protection against Covid-19, we need to prepare for the possibility of needing booster shots to counter waning immunity and to keep pace with an evolving virus, National Institute of Allergy and Infectious Diseases Director Anthony S. Fauci said.
The key benefit of self-replicating vaccines is their efficiency, as they require only a fraction of the dosage of conventional vaccines to trigger a strong immune response.
