Quick takeaways
- Scientists have discovered a way to mimic the health benefits of young people's blood transfusions without the need for actual blood, using an arthritis medication to block a signal linked to inflammation and rejuvenate blood stem cells in aging mice.
- Consuming cinnamon may have positive effects on brain health, including improvements in cognitive function and memory, due to its active compounds that reduce oxidative stress and potentially act as a dementia preventer.

Young blood transfusions without actual blood
Scientists have discovered a way to mimic the health benefits of young people's blood transfusions without the need for actual blood. By using an arthritis medication called anakinra, which blocks a signal linked to inflammation, blood stem cells in aging mice were returned to a younger, healthier state. The mice experienced longer lives, improved cognitive abilities, and increased energy. The medication worked best when taken consistently throughout life rather than started in old age.
