Sunset over @Penn after yesterday's snow showers cleared out

@JohnBolaris A quick note of appreciation for your knowledge, insight, and passion for meteorology. It would be great to see you on air again someday, but following you on X is the next best thing!

New Jersey Snow totals Mt Holly 14 Cherry Hill & surrounding towns 12-16 Pockets of 18 inches AS OF 9AM Monmouth county Freehold 24.2 Cranbury Middlesex county NJ 21 Ridgefield Bergen county 20.6 Mt Holly Burlington county NWS 19.2 Monmouth county 18.2 Colts Neck 17.8 Cape May county Dennisville 12 Wildwood 8.7 Mays landing 14 Margate 13 ACY Airport 14.5 The Lehigh valley..from Allentown to Reading escaped the Heaviest snow General amounts 3.8-8 inches Once you got North and west of Quakertown amounts drop off dramatically ..Quakertown 8 Mt Pocono region 4-8 inches FYI My post yesterday afternoon I indicated thinking of trimming distant NW burbs , but I didn't as I thought it might create confusion across our closer NW Burbs

@RENEGADEARTH494 @A_K_Mandhan ...and, if recollection serves, a jewelry shop and a flower shop for those times when a significant-other would like to pick up something because they'll be home late...!

@A_K_Mandhan There is a pizza place inside the pentagon. You can’t have pizza or any kind of food delivery just dropped off at DOD headquarters. It’s Super Bowl Sunday. Correlation is not indicative of causation.

BREAKING: Pizza restaurants near The Pentagon seeing a 250% increase in order activity. ... show more

@briannalyman2 Your summaries are fantastic! I grew up in Boston (the Freedom Trail was part of my 4th grade curriculum) and I have been living in Philadelphia for nearly 40 years. I am looking forward to hearing more about Philly history in the coming year...

Imagine it’s February 4, 1776 You’ve just arrived in NYC on orders from Washington. Your job: prepare this city for war. You think it’s just pre-emptive, but suddenly a courier rushes over to you with intelligence that stops you cold.

@Mr72Capital @afneil To be fair, I've never seen the T5 Concorde Lounge crowded, or even half-full. Additionally, the Lounge staff were very helpful when my son missed a connection last year, they worked everything out seamlessly. For better or worse, I will be loyal to @British_Airways to the end!

Outside of the Gold Check-in at T5 and T5 security line there really isn't much point in being a BA Gold Member anymore. The First Lounges are poor and very full of Partner Airline Members. Anyone from Bronze upwards is in the Priority Boarding Line and on the way back the Business Class Check ins are just airport contractor services and often busier than the economy line. Rather than incentive, all they have done is put up penalties (like having to pay to select a seat on a business class booking). Avois values keep falling and in 20 years of Gold membership I have NEVER been upgraded, in fact been downgraded 3 times on overbooked flights. I soldiered on this year but have largely drawn the same conclusion as you. I'll just book Qatar directly and join their programme.

Sure. It won’t make any difference. I don’t have the time to make up for your inadequacies. You have launched a fatwa on your loyal high paying customers for reasons best known to yourselves. I will have done six first class returns to NYC in the past year plus first class return to Sydney and numerous Nice-London business class. Yet I still won’t be able to renew my GGL Group O status. If I don’t qualify who does? No matter. I have gold for life which means I can always use your lounges. But instead of always travelling BA I will look for better more convenient deals with other airlines eg Nice to NYC direct, forget BA out of London. Why you would treat someone like me like that baffles common sense. But BA, not me, will be the loser, especially if I decide to broadcast my experience to my 1.2m X followers and on Times Radio and Mail columns. At the moment you’re a case study in an historic British brand gone badly long. I might make it my business to explain and expose why. You’re interesting as a business case study in stupidity. @britishairways

Very proud of @PennChemistry senior @KristinOsika, who will give the Founders' Award Lecture on Tuesday afternoon at the 29th Enzyme Mechanisms Conference! For additional details, see her recent paper in @PNASNews, accessed more than 1000 times to date: lnkd.in/eaK4RjAM

@RolandDunbrack Same results here

Congrats to former grad student Dr. Sam Eaton, who discovered that @GSK 4394835A is a reversible covalent inhibitor of PDE3B by redetermining the structure of the enzyme-inhibitor complex. pubs.acs.org/doi/10.1021/ac…

Just out in Biochemistry – congratulations once again to former grad student Dr. Matthew Gaynes @MNG_Chem (now a postdoc at UCL @PennSAS senior @KristinOsika! pubs.acs.org/doi/10.1021/ac…

@BillKristol Were you a bandie...?!

As darkness falls on Thanksgiving day, one last thought in the spirit of Thanksgiving: Illegitimi non carborundum.

Bella's plan for Friday night...!

Congrats to @PennSAS senior @KristinOsika, just selected for the Founders' Award at the 29th Enzyme Mechanisms Conference! Kristin's award lecture will focus on her pioneering work with drimenol synthase, as outlined in her recent @PNASNews paper: pnas.org/doi/10.1073/pn…

After giving a lecture earlier today at the @UoMMIB in Manchester, UK, my hosts took me to the Midland Hotel, where in 1904 CS Rolls and FH Royce met to form the venerable Rolls Royce company! @rollsroycecars

I had a delightful visit to ⁦@ITALFARMACO⁩ in Milan yesterday to discuss our mutual interests in HDACs. Their inhibitor Givinostat was recently approved for the treatment of Duchenne muscular dystrophy.

Surprise! former grad student Dr. Sam Eaton and I re-refined the structure of the PDE3B-GSK4394835A complex [Rowley et al. (2024) J. Med. Chem. 67, 2049 (PDB 8SYC)], discovering that GSK4394835A is a reversible covalent inhibitor. See: biorxiv.org/content/10.110…

Taking the water taxi from Back Creek to Annapolis City Dock to see the Sailboat Show!

@organomimetic Beautiful work! As for "who cares", you had me with "B" (boron)!

Congratulations to Andrew Baublis on a new publication exploring the fascinating chemistry of B-carboranyl stannanes and germanes! Now, you might be wondering, who cares about these unusual, almost alien-looking molecules? Ge doping lays a critical role in the semiconductor industry, where controlling how atoms behave at the nanoscale determines the performance of modern electronics. The challenge is finding thermally stable and well-defined molecular precursors, and that’s exactly what this work provides entry into. Stay tuned as we keep uncovering how these seemingly “weird” molecules might shape the future of advanced materials! pubs.acs.org/doi/10.1021/ac…

A new class of terpene synthases in giant viruses? Dr. Eli Wenger & I comment on this recent discovery at the interface of living and non-living systems [Park et al. (2025) Biochemistry 64, 3866]: A Giant Step for Terpene Biosynthesis | Biochemistry pubs.acs.org/doi/10.1021/ac…

Congrats to Dr. Matt Gaynes @MNG_Chem for successfully defending his PhD dissertation today – Welcome to the ancient and universal company of scholars!

I walk past this bust of Nikola Tesla every day that I give my lectures at Penn – it is located in the lobby of the David Rittenhouse Laboratories, where lecture halls used mainly for science and engineering courses are also located. @elonmusk, does this look familiar?!
