It’s been a mystery why Roman concrete often lasted thousands of years, but ours decays in mere decades. Turns out they incorporated chemicals in a process that induces self-healing; scientists at MIT just figured this all out - in 2022. Extraordinary. news.mit.edu/2023/roman-conc…

My take: We will soon have 2 groups in the US (& eventually the world): the vaccinated & those with the Delta variant If you have access to a vaccine & choose not to take it, you are choosing to get Delta. Delta probably won't kill you, but it might! get vaxxed

Earth's "COVID Melanoma" primary tumor (infection) was not initially treated successfully- the margins were not clear, allowing cells (virus) to escape and metastasize. Those COVID metastases were widespread. Earth's immune response was not well coordinated. The mets thrived.

A Chemotherapy (vaccine) was developed that would wipe out the original tumor (virus). But the mets had developed new gene defects- what had been a monoclonal cancer (virus) has become polyclonal, with many variants. The chemotherapy won't kill all the variants.
For those of you keeping score at home 26 million Americans are known to have had COVID 420K of them died from COVID 29 million Americans have gotten COVID vaccines 0 have died from COVID vaccines When it comes to generating immunity vaccine > infection Easier, way way safer

Reports out of @StanfordMed that non-patient facing employees are receiving vaccines before residents and fellows. Only 7 out of >1300 trainees have been vaccinated. Protests underway now. #ThisIsOurShot

It’s still wizardry as far as I am concerned.

This is Maureen Healy's statement. Mo is Professor and Chair of the History Department at Lewis and Clark. She was injured in the head by a shot fired by federal government paramilitaries while demonstrating peacefully in support of Black Lives Matter. #PortlandMoms #blm #mohealy

It turns out literally nothing happens in the heel pad. Hence the literature is generally case reports rather than a series of any particular mass. The result? No good pre-test probability as to the benignity or malignancy of a soft tissue mass. Imaging doesn’t help either.

Here’s the associated MRI showing planter fasciitis and the (nonspecific) enhancing mass:

Read & share this beautiful, inspiring story in today’s @washingtonpost about an ALS researcher at @UCSF who was diagnosed with #ALS. It seems like “’the universe is playing a cruel joke on us,’” says Dr. Rahul Desikan. wapo.st/2MspEe7 #ALSResearch #ALSAwareness
