You know I thought they have been rock solid for like ~50 years on average...

If needed You can do a CBP tariff exemption form. I just had to do one for a bruker purchase that wanted another 100k in tariffs.

I feel like now will be a rush to get the rest of the remaining 4 letter PDB codes...

In a couple of weeks we will be dropping a preprint (w/ one of the coolest PDB codes btw...) so stay tuned...

it would be great if each journal had a list what each status for their "manuscript status" types mean somewhere.... and the NIH too...

Me: ordering Girl Scout cookies online feels so wrong

Also me: oh (grad students kid) has a link to order send it my way…

The number of folks that have still asked for letters despite me answering this way is still surprisingly high…

living in san diego this is a real fear of mine. It was a high of 75 yesterday, if i couldnt have gotten my afternoon ice coffee while on my daily beach walk in between meetings how could I do my job?

Did I miss something? I have been using it for like 5 years and never had an issue. I sat this cycle out but did they change it ?

I’d argue that model proteins already exist and those of us who work with them (e.g. gb1 or ubiquitin) to benchmark new biophysics constantly get criticized for how relevant these studies are and being told to do it on a real protein.

Really cool work from Eugene’s group. I got to hear about it straight from the source at the protein folding dynamics conference this week!

Some Pielakers past and present and honorary took Gary to an airplane museum today during the GRC! What a thrill!

My postdoc advisor is an advocate for the β€œpost faculty fellow” positions and in theory it sounds like a super cool idea.

That being said if anyone is wanting to do one in my lab, Please email me a CV and cover letter.

Yeah the science is awesome and keeps me going and all, but what makes me proud? Def seeing my students learn/tackle complex problems/have their hard work pay off.

having sat behind the penguins bench for four years i totally agree with this.

Ill add more context when I get back from HI, but we were able to make mimetics for high mannose glycans (HMGs) such as man-5, Man-9, as well as competitive inhibitors to HMG binding to the model lectin GRFT. These tools also let us investigate intramolecular avidity GRFT uses to recognizes HMGs.

Tunable multivalent Fe(II)-based glycoassemblies as mimetics for native high-mannose glycans. High Mannose Glycans (HMGs) play key roles in eukaryotic biology, regulating processes ranging from protein folding to host pathogen defense. Lectins have evolved to interact with these glycans throug...

Really excited to share a manuscript from the group. Here we worked with Julia Staubers group to look at Fe(II) based glycan displays as glycomimetics for high mannose glycans.

I heard the gingerbread man was tortured by lord farquad on plum island too. Maybe if the Lyme disease was released from there we can figure out what happened to the gingerbread man next.

i received my first "hate mail" this week from a retired big name in my field. Essentially he said my recent work was trash and I didnt read/cite one of his papers from the year i graduated high school (shockingly it was irrelevant to the story). Do I respond or nah?
