Hi James,
The elevator pitch has to be 90 degrees, no? Otherwise it would travel
horizontally as well.
Or, perhaps, we should petition these types of elevators to be added to
building codes for large, multi-entrance buildings?

Excellent idea, Mark!
I think the solution to your dilemma is rather straightforward: we
introduce a Winter Standard Room Temperature (WSRT) and a Summer Standard
Room Temperature (SSRT). This way, the folks from locales closer to the
equator can always use SSRT, while those from more temperate

Sad news indeed for so many of us, those who knew Alexei personally and
those who benefited professionally from his selfless dedication to
computational crystallography.
A wise man once said something along the lines of anyone successful today

Hi James,
This meeting has indeed been one of the best ones by its format, content,
and atmosphere. Many thanks to all the organizers and attendees of the
past. Nevertheless, it is not surprising that it was cancelled, given the
trends in structural biology research. Straightforward evolutionary
Hi Carmien,
It appears to me that the dewars in your first link are those made by
Taylor Wharton. You can do a search with that name and hopefully find less
expensive options. We've used them for many years and they are good.
Another one, you could try, is VME https://mvebio.com/aluminum-dewars/
Hi Jessica,
Your subject being membrane proteins, I might ask a question if your
conclusions and claims are commensurate with the data quality but as
Eleanor says, it really depends on what you are actually claiming and what
kind of data you have.

While the progress in the digital world in 2021 over the 90s is undeniable

keep in mind that some institutional accounts may filter out the

I would not be surprised if some of
Hi Rob,
There is no information provided to think what might be the problem with
indexing. How confident are you in the direct beam coordinates?
Are any of the cell lengths long-ish?
It may not be enough but at a minimum, two images 90 degrees apart might be
helpful.
Preferably, they would be
Dear Saurab,
It's a shame these crystals do not diffract well - they look so good!
I assume the diffraction you saw was recorded at cryo temperatures? If so,
it is possible that you may be damaging the crystals during cryo-pretection
and cryo-cooling. Before you go too deep into changing the

Is the oxidation state of the coordinated atom, or the identity of that

If there was a very slightly bigger atom, it would take care of the

bit, which in turn could take care of the negative ones.

Hi All,
Adding some more details to what's been said already. Only because I've
seen too many times the polarizers being used incorrectly.
First, you need two polarization filters which are typically called
polarizer and analyzer. First one (the polarizer) lets through only the
light waves of a
Hi Robert,
In addition to the great suggestions you already have received, maybe you
should also consider SIMBAD or similar programs? The behavior you are
describing is typical of, albeit not exclusive to, having crystallized a
contaminant protein.
Good luck!

Hi Jessica,
You do not say how well is the rest of the structure refined.
First, you should refine the structure best you can, without placing
anything in the unclear blob of your interest so to obtain the best
possible phases and hopefully improve the blob density as well.
Then you should let the

Obviously, one would need a lot more information to properly diagnose the
problem and I am sure much smarter people them me will ask you for that.
But just to move the task by couple of steps, I want to point out couple of

If there is radiation damage, for every "new" positive density there should
be a negative density in the original position. From the pictures we've
seen, it seems unlikely.

Dear Scott,
For the grant application, better question might be how many structural
biologists are out there, because "a crystallographer" may be interpreted
differently depending who is reading the grant application: are these the
people who know crystallography, or people who solve structures
Hi Aleix,
Can you describe how you did the fluorescence scan, or share the plot
itself? I am asking this because you say you could discard Fe, Zn and As/Se
but you don't say anything about Cu which is in between these elements.
If you tried but could not discard Cu, then it could be your

Hi Ethan,
I am not a linguist of Greek or even of English but I would assume that
the term cryo-cooling is advocated not by DRD but by the people who
want to distinguish between cooling down to *cryogenic* temperatures and
say, cooling from 25 C to 4 C.
