After CDC shooting, its employees turn their anger to RFK Jr. and Trump Investigators allege the shooter targeted the agency because of his coronavirus vaccine beliefs, according to two CDC officials briefed on the case.

NEW: The CDC shooting was much worse than initially reported. 181 rounds. 150 windows hit. Staff are furious at RFK Jr. and Trump becuz their long-running fears about anti-vax rhetoric turning deadly seem to be vindicated. @laurenweberhp.bluesky.social + Me.

Thank you all for the concern. We are all alive and OK-ish following the targeted attack on the CDC in Atlanta.

Supplements: too good to be true?

Supplements: too good to be true?

The dietary supplement industry in the United States is estimated to be worth $70 billion or more. The supplement market grew by 50% from 2018 to 2020. It is estimated that 100,000 unique supplements are currently available for purchase.

The FDA requires the following disclosure be displayed on the package of all supplements: "These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, or cure, or prevent any disease." Be skeptical of any supplement that is marketed with claims contrary to that disclosure. Always consult with your primary care provider before starting or stopping any supplement regimen.

Harvard Health reports on the recent ruling that the makers of Prevagen can no longer claim their #supplement improves #memory. The author recommends being wary about supplement marketing claims, which are often false, misleading, or based on insufficient research.

Started off this morning emailing my Senators and Congressman about the NIH and the potential damage being done by unnecessary disruptions.

They need to hear from us loud and clear. Constituents matter to them as one of the primary purposes of a politician is to get re-elected (and its their job).

Excited to share the lab's recent publication. Granulins are critical for lysosome function and brain health to prevent neurodegeneration. Our data suggest that granulin peptides could be used to treat frontotemporal dementia (FTD), Parkinson’s disease, Alzheimer’s disease.

Very happy to share our paper on Familial British Dementia (FBD) which is online today!

Using patient iPSC,we show the amyloidogenic peptide in this disease -ABri -is mainly produced by microglia…
