This was a topic discussed in my group this week. anyone who might have a decent answer for this and or how to show an official transcript when they have not completed a semester yet ... we are all ears on suggestions...
Any advice on what first year grad students should enter for their GPA as they do not yet have grades? 0.0? (NA is not accepted by system)

April and I went to a Wizard of Oz themed party tonight, she went as the beautiful and elegant glinda, and I decided to be the yellow brick road. It was a fan favorite.

This is absolutely heartbreaking, Zara was an absolutely wonderful person and wonderful scientist. She also had a great taste in cocktails bar as we realized we were both regulars at Butterjoint in Pgh during different timeframes. She will be dearly missed.
Zara Weinberg was a brilliant light both in and out of science. She changed the lives of everyone she interacted and loved for the better. Her legacy will live on through all of us and we will fight for a better world on behalf of her memory.

Whenever Angela talks about our work on y-crystallins/cataracts she prefaces it by showing Monet's work pre and post cataracts.
In 1911, Impressionist painter Mary Cassatt was diagnosed with cataracts, where lenses in the eye become clouded with protein deposits as we age.
A failed cataract surgery left her essentially blind. Her last painting was 1914.
Claude Monet was diagnosed with cataracts in 1912...

NMRSky! Is there any way to indicate multiple peak assignments for a single spin system (I.e., exchange where two peaks for one amide are visible) in a BMRB deposition? @nmr900.bsky.social
