The potential for severe storms producing locally damaging wind gusts has increased for this afternoon and into this evening. We also cannot rule out the possibility of an isolated tornado. The greatest risk for any severe weather remains across eastern PA and the Delmarva.

Our NIH grant to discover coronavirus antiviral meds was terminated today. With this grant, we had developed a better SARSCoV2 inhibitor than Paxlovid, and we recently discovered an improved drug that looks better than Pfizer's own second-generation inhibitor.

Down over 60%. That’s how far federal research funding has fallen compared to this time last year. Every delay in funding is a delay in delivering for the health of American people.

A federal judge has issued a permanent injunction blocking the plan to cap NIH indirect costs at 15%. The judge highlighted that the policy would have caused “imminent risk of halting life-saving clinical trials” and “disrupting “innovative medical research and treatments”.

A major nature paper this week found a significant decline in dementia after an outdated Shingles vaccine. I've reviewed the study and many other relevant ones in a new Ground Truths (link in profile)

A new analysis of a vaccination program in Wales found that the shingles vaccine appeared to lower new dementia diagnoses by 20% — more than any other known intervention. #StanfordMedicine stan.md/4lvDUnd

The response below from ChatGPT seems consistent with the 32P and 35S radioactivity pricing I recall from the 90's (when I was a tech at Children's Hospital at Harvard Med). There were many vendor options then. It is staggering what we (and there will always be many of us) have
