Someone said it’s unethical to restrict the movements of elderly people when there is a covid outbreak in a nursing home.
Doesn’t feel too ethical to me to have low vaccination rates, no air quality improvement, and just spread diseases either though.
Seems kinda evil.

Canada has just lost measles elimination status. The U.S. will undoubtedly follow shortly.
Elimination means that there is no continuous spreading of measles within the country for a year or longer.
Canada and the U.S. have blown it, and it’s largely the fault of the anti-vaccination movement.

Canada loses measles elimination status after three decades, health agency says
Canada has lost its measles elimination status after nearly three decades due to its failure to curb a year-long outbreak, the country's public health agency said on Monday.

A study with data from ~14 million children shows that COVID19 infection is significantly more harmful to kids’ hearts than the vaccine.
Marty Makary falsely alleged that “children died” because from COVID19 vaccine. Whomever told him that failed to account for SARS-CoV-2 infections.

My university offers Communication in Science, but it isn't required for any of those departments. It's so important we try all the angles to change how we communicate about science.
When science is understandable, we all win. I've started a national petition calling on all institutions of higher education, and their accreditors, to require science communication and public engagement training for all STEM degrees.

Can't emphasize how damaging this is. A single non-scientist—Peter Bogner—holds all power & makes all decisions at GISAID & provides no justifications for any of them, except blatantly false ones.
He has that power because he conned rich & powerful people into giving it to him. Enough.

Using cryo-EM, they found metformin enters complex I only when it is open and blocks CoQ10 in the closed state, revealing why it’s safer and effective.
