Are you calling them Moon fries even though they are grilled because you can't fry stuff on the Moon yet? 🍟🌝

powerthesaurus.org is obviously another thesaurus, but I can use multiple words as a query. I tried "very innovative" again, and it gave me some decent results.

losethevery.com is essentially a thesaurus for adjectives that you put "very" before them. I just tried "very innovative," and it gave "not yet added," so I suppose there is a room for improvement 😂

My PhD advisor taught me this trick: google terms that I am not sure which one to use (e.g., timepoint vs time point) and go with the one with more results. Google stopped showing # of hits for searches, and I didn't know how to do it anymore. I can do it with books.google.com/ngrams!

Speaking of firing, why don't we fire people with "bad Behaviour" who are not doing their jobs instead?

Have you heard of optical nanocircuit? It's analogous to RLC circuit that picks up radio signal, but this nanocircuit picks up and focuses light like a nano-magnifying glass useful for sensing molecules and building quantum computers. See the work from Seungwoo Lee's lab! 🧬🔍

Holy ****!! In hindsight, it is so obvious why this virus looks like a bullet. I remember looking at the cartoon depiction of HIV for the first time and thinking "why the hell does it look like that?" Crazy biology 🦠🧬

Wow, this DNA origami shell is >10 µm in diameter! The @simmellab.bsky.social built upon their previous work on "Dipids" (DNA origami subunit that acts "like" membrane lipid monomer) to accomplish this feat, using lipid vesicle as a template. 🧬🟢

mRNA-DNA hybrid origami from the Tikhomirov lab at Berkeley! I can't wait to see how these structures would function in cells 💪🧬

Thanks for sharing. It was a whole lot of American History lesson for me! We tend to experience our lives in such a delta function potential manner in space and time, so it is important to put our current experience in a larger perspective.

I recently read "How to Win Friends & Influence People" by Dale Carnegie (1936) and observed an interesting phenomenon: everyone around me knew of this book but never read it except for my brother-in-law. Who heard of this book, and who actually read it? Is there anyone who has never heard of it?

An oldie but a goodie. I didn't realize that the push for soft money (aka pay your salary with your own grant) happened so recently in the turn of the century. I recreated Fig. 1 with more recent data, and we seem to be equilibrating?

Reporting back on this: the space seems to be converted into an office/research area and is currently undergoing renovations. There must be another place I can go to relax and read physical copies of papers... I will just have to look around the campus for it 😅

Aside from its witty name, WithdrarXiv gives a pretty interesting insight:

withdrawals, most arXiv retractions stem from factual or methodological errors (37%) and incomplete work (19%)."
