Odd-looking cloud over Philadelphia yesterday afternoon 2:53 pm, ahead of a squall line that brought sleet to Center City. @DrewForecast, I didn't see any rotation, so this couldn't have been a nascent tornado, right?

@Math_files If you had ever witnessed the suicide of a college student, you would not be amused. This is shameful.

@AMGulick_Lab Wow, that's an amazing story and clever detective work!

Excited to see "Orthogonal Tandem Catalysis in Terpene Biosynthesis" just published online in Curr Opin Chem Biol! This review highlights common chemical strategies for "one-pot" synthesis in the lab and in the cell. https://t.co/rgYxiAl3ja

@kamerlinlab still holding on!

Sometimes it is difficult being an @Eagles fan. After they lost the game in London in the last second of play on Sunday, this meme came to mind... #PhillyLife

@GBHArchives I think I know some of those students! I was resident tutor in chemistry at Mather House during Hurricane Gloria.

@JoshMalina This is nonsense up with which I will not put!

[ChristiansonLaboratory @ChristiansonLab]

@MichaelLinLab @jdpereira Oh no, the university isn't doing something right, this is unprecedented!!
Instead of criticizing a young faculty member on X, you might reach out directly to leadership at @JohnsHopkins & @JHUCompSci to share your concerns, e.g., VPR @deniswirtz. You seem to care a lot.

@aug5thmusic It is nice, but it doesn't sound like Bach to my ear

@WesFarrell @NavalAcademy Congratulations to all! I like the monoterpene connection... Best wishes from Back Creek

@MichaelLinLab @JHUCompSci Happy news for young faculty should be celebrated - this is part of our mentoring responsibilities. No need to throw shade on @JHUCompSci and their talented young faculty member.

@Becketh711Dan When I disembark in such circumstances, I usually ask, "So, which one of you was a Navy pilot?" 😄

Congrats to @KristinOsika , Mason Leffler, and Abbi Czarnecki for their fantastic work with drimenol synthase, a class II bifunctional terpene synthase! Covalent linkage of catalytic domains enhances product flux, consistent with substrate channeling. https://t.co/fVKgl2K1We

@June52352847 @Gabriele_Corno We did, too, and it was the same for us. Outside, the dog would run circles around our firstborn and "herd" her so she wouldn't wander off!

[ChristiansonLaboratory @ChristiansonLab]

@elonmusk Always proud of our Penn alumni!

[ChristiansonLaboratory @ChristiansonLab]

@history_dame And they sometimes put on public display the Book of Common Prayer in which the Rector, Jacob Duché, crossed out the name of the King on July 4, 1776 – an act of treason. Duché was also chaplain to the Continental Congress.

@HomerPavlos Καλή Ανάσταση

This wouldn't be a problem if we simply read the papers that we cite. Isn't this what we all teach our students to do??

Hallucinated citations are polluting the scientific literature. What can be done? https://t.co/x7LxPyhm81
