We are studying the biology of wound healing, using the smallest possible acute vascular injury we can imagine—a 5 um micropoint pulsed laser deformation of the endothelial cell plasma membrane. 🧪 #MedSky #EMSky #EMedSky #immunosky

How do you explain to your kid why one of his hero’s #BélaFleck cancelled his #Kennedycenter performances? We don’t do art for the money, or for political gain. The focus should be on the music. Thank you Béla for doing the right thing and being a role model for the next generation.

My thoughts on ABC news- Scientists, not political appointees, should be who advises the public on clinical guidance. RFK needs to meet with CDC career leaders and learn about the agency's responses to outbreaks and overall programs vs directing CDC website changes based on ideology not science
Video Former CDC chief on agency webpage saying autism, vaccines link ignored
Dr. Debra Houry, who resigned from her position as chief medical officer of the CDC in 2025, called the change on the CDC’s website "disturbing."

In their juvenile stage, terrestrial Eastern Newts (Notophthalmus viridescens), also known as red efts, produce tetrodotoxin, the same NaV channel blocking-neurotoxin as pufferfish. The striking coloration is an aposematism.
