Seek immediate medical care if baby shows:
👉 Poor feeding
👉 loss of head control
👉 difficulty swallowing
👉 decreased facial expressions

🧠Injecting SARS-CoV-2 spike protein RBD into the brains of mice caused depressive behavior by lowering astrocyte Cx43 and disrupting gap-junction communication.

Treating the mice with Celecoxib or restoring Cx43 levels reversed these effects. buff.ly/Q2RHx3h

#medsky #neurosky #psychsky🛟🧪😷
COVID and Depression. Injection of spike protein RBD into a mouse's brain causes astrocyte Cx43 decrease and stops astrocyte connections which leads to a sad face. Giving a pink pill that is celecoxib turns it to a happy face.

Study of >11,000 children with atopic dermatitis (eczema) shows that COVID vaccination has additional benefits including:

✅ Fewer COVID infections
✅ Fewer other infections (pneumonia, ear, skin)
✅ Less allergic reactions (asthma, food anaphylaxis)

In a RCT, Urolithin-A boosted CD8⁺ T cells and improved immune metabolism, hinting at a new way to slow age-related immune system decline and inflammaging. buff.ly/qaGyGF0

Urolithin A works by inducing mitophagy (clearance of damaged mitochondria).

Double check the AI assistant's answers!

Or better yet, get your news from known reliable sources.

BBC: Largest study of its kind shows AI assistants misrepresent news content 45% of the time– regardless of language or territory buff.ly/KZ10ZkW
Key findings: 45% of all AI answers had at least one significant issue. 31% of responses showed serious sourcing problems – missing, misleading, or incorrect attributions. 20% contained major accuracy issues, including hallucinated details and outdated information. Gemini performed worst with significant issues in 76% of responses, more than double the other assistants, largely due to its poor sourcing performance. Comparison between the BBC’s results earlier this year and this study show some improvements but still high levels of errors. Graph showing 5 AI assistants and their accuracy- dark purple is significant problem with accuracy, light purple is some problems with accuracy.
