Looking for a chemistry summer read? Ever wondered how superbases work?
Our most recent article-review (with @evaheviagroup.bsky.social ) breaks down exactly how adding alkali-metal alkoxides to main-group reagents can change reactivity and selectivity in organic synthesis.

As someone who studies autoimmunity "boosting your immune system" is how you get multiple sclerosis, diabetes or die as your immune cells slowly kill every other part of you in an orgy of violence. However, this list is a way to boost your immune system in a targeted way without incurring ANY risks!
Doctors are AMAZED at these 10 ways to BOOST your immune system:
The Tetanus vaccine
The Measles vaccine
The Polio vaccine
The Mumps vaccine
The HPV vaccine
The Pneumonia vaccine
The Hepatitis B vaccine
The Rubella vaccine
The Diphtheria vaccine
The Covid-19 vaccine

Such a nice structure!
The structure of unsolvated neopentyl sodium has been reported by @evaheviagroup.bsky.social in Angew. Chem., revealing a rare tetrameric motif.
Combined with a Lewis base, it can metalate non-activated arenes and alkenes.
