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.

May we fight each day to build the future Zara imagined. The world lost a genuinely good human but her power to inspire our community will persist 💔
Truly one of the best. We worked on various initiatives/wrote a paper together, and had the best conference meet ups. She was a bold and tireless advocate for change. Last time we met, we had a great time trying new cuisine and imagining a future that’s so different for trainees than we experienced.
Zara Weinberg was a brilliant, loving, and beautiful woman. She inspired everyone who she interacted with, and always strived to make the world a better place for everyone. Tho the world is a little less bright today without her, her memory will always be a blessing.
She was truly one of the best.

"feels like" is correct because it gives the IMPRESSION of expertise. Just asked GPT5-Thinking a few questions I had asked my PhD students this week... let me tell you, our jobs are safe in this regard LOL

Capsule blocks conjugation, preventing MPF between donor:recipient. However, conjugation exploits recipient strain heterogeneity of capsule thickness, conjugating to cells with less capsule
