Building Blocks of Memory in the Brain

https://www.youtube.com/watch?v=X5trRLX7PQY&t=1460s

This video describes memory formation and retention as a competition between different neurons. 

I have heard this before.

I wonder if more biological processes involve competition between cells.  We know that some cells self-destruct when they detect a defect or an infection.  Competition might be a method by which biology optimizes its functioning.

Fwd: Watch "Mass Illness Hits Cruise Ship — CDC Sounds Alarm" on YouTube

The older I get, the less I like to travel.  I tend to get sick easily.  

Best wishes,

Just another norovirus outbreak on a cruise ship. CDC has reported 12 gastrointestinal outbreaks on cruise ships this year.

Chemo is Weird, Y'all

Been watching this YouTuber, Hank Green, for about 13 years.  (The first video I saw is this one:  https://www.youtube.com/watch?v=yRRGaxx8Zf4)

A couple of weeks ago he announced that he had lymphoma:  https://www.youtube.com/watch?v=x6a4hMyiwBo

He alternates making youtube videos with his brother John, who wrote the book, "The Fault in Our Stars" which was made into a terrific movie.  John Green appears in a deleted scene of the movie:  https://www.youtube.com/watch?v=PEEQ6-4nKYQ

"I looked at the recent bird flu data, and now I'm really scared."

An elderly friend of mine in Salt Lake City died from the flu.

According to the video, there is no pandemic of the Bird Flu right now, but conditions are ripe for one to happen.  It has infected animals close enough to humans for it to have the potential to spread to people.

The video claims that public officials are trying to prevent an outbreak.  It would be good if we could avoid another pandemic.

Does COVID Mess With Your DNA?

https://youtu.be/6q_Sf4I0Bp0

What I gather from the video is that the methylation of genes is a natural bodily response to infection. People with long COVID appear to have overly persistent and/or inappropriate methylation leading to chronic inflammation.

Your Brain Is Shaped Like Nobody Else’s - Nautilus

growing body of research now confirms there are plenty of physical dissimilarities between individual brains, particularly when it comes to white matter—the material nestled beneath the much-prized gray matter. And it's not just anatomical. White matter hosts connections between the brain's sections, like a city's streets and avenues. So behavioral patterns can arise from even small physical differences in white matter, according to a late 2022 Science paperpenned by Forkel and a colleague.1

"76% of the people in Hong Kong who died of COVID were vaccinated"

There are problems with this idea.  People in Hong Kong don't get the same vaccine as Americans.  Most get the ineffective Chinese vaccine.  You would have to compare the death rates with other people in the world.   

The overall mortality rate in the United States among the unvaccinated has varied from 2 to 10 times as much.


"In January, only about 25% of Hong Kong residents aged 80 and older had been jabbed, with the rate among care home residents even lower. Almost all of those who perished in the fifth wave, about 72%, were unvaccinated."
