A hundred years ago, the average life expectancy was <50. Today, it is ~80. What made the difference? Public Health. Public health, however, is not some magic entity happening in a vacuum - it requires people. Without those people, there can be no Public Health. That serves no one. Wake up.

America will be less healthy & less safe as a result of Peter Marks' forced resignation from FDA. He & FDA protected us from people who enrich themselves selling snake oil: unproven stem cell therapies, vaccine alternatives, other fake treatments. Thank you for all you did for public health Peter.

House cuts to NIH (to fund billionaires) would cut the Cures Act (passed with bipartisan support) by ~$300 million or 70%. Scientific loss includes cancer research, adult stem cell research, brain/dementia research, and a critical data collection project to study rare diseases, among other topics.
Additionally, the Cures Act provides multiyear funding to four highly innovative scientific initiatives:

The All of Us Research Program, formerly known as the PMI Cohort Program,
The Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative seeks to better understand how the brain encodes, stores, and retrieves information, which will transform the ability to diagnose and treat neurological/mental disorders.
The Cancer Moonshot℠
The Regenerative Medicine Innovation Project will support clinical research in coordination with the FDA using adult stem cells to further the field of regenerative medicine.
