Vitamin K-dependent carboxylation in osteoblasts regulates bone resorption through GAS6

Studies in humans suggest that vitamin K is involved in the regulation of bone remodeling, but the precise mechanism at play remains unknown. In cells, vitamin K functions as a co-factor for the g-glu...

A big study in JAMA last year in which 185 909 children were exposed to acetaminophen during pregnancy. Conclusion: Acetaminophen use during pregnancy was not associated with children's risk of autism, ADHD, or intellectual disability in sibling control analysis.

I was on a H1B visa while I was finishing my postdoc training in Columbia University in NYC in 2012! If that will be today, I will have to pay 100K$! 🤯

Gergely Orosz @gergely.pragmaticengineer.com · 22d

Those on an H1B cannot return to the US from tomorrow (Sunday) unless paying $100K. This is an out-of-the blue presidential action. We’ll see software engineers stranded abroad.

One easy to predict outcome: those on US visas will travel less… for work, for conferences etc.
