No molecular chirality. Intermolecular hydrogen bonding is possible though.

Those are really cool images as well! We do not see twisted (yet) but see some evidence that there is a connection (hard to avoid pun) in some cases between chunkier crystals and thin rods. I have had three different students grow these oddities since at first I was uncertain if it was real.

Anyone ever seen such crazy crystals before or know what's going on? #chemsky

They were passing out these notes for upcoming Jon Husted protest at the No Kings rally in Cleveland yesterday. I also noted this very large banner. #NoKings

Terrific turnout for #NoKings Cleveland today!

Very easy way to support NSF!

Great rally for Science in Pittsburgh today!

Never Over | 2026 Team USA Winter Olympic and Paralympic Anthem​ YouTube video by Eli Lilly and Company

NSF building on Eisenhower Av. HUD now owns.

Destroying the NSF mural in the foyer. Of the Eisenhower building.

The National Science Foundation sign on our Eisenhower Av building is now gone.

The NSF mural in the foyer is removed and torn off in sheets.

We were supposed to celebrate the 75th anniversary of the agency in May 2025. That never happened.

And one of those happens to be a major holiday…..SMH

Short window?!

NSF pares down grant-review process, reducing influence of outside scientists Memo cites overburdened staff, but some say move also aims to elevate White House priorities

Let's be clear: the US National Science Foundation's decision to reduce the role of expert panelists and outside reviewers does not limit the burden on NSF workers; it empowers them to make funding decisions without scientific oversight.

So my grad student was trying to grow single crystals of a new compound for X-ray crystallography, and instead got candy canes, a packman, and other alphabet letters.

If the crystals could now self assemble into necessary text for a manuscript then life would be good....

To all of my friends at NASA, NSF, & NOAA - thank you for all that you do.

Wonderful science showcased on BlueSky daily! But usually no mention of who funded the work. At a time when federal agencies such as NSF, NIH, etc. are facing challenges & uncertainties, scientists should also acknowledge sponsors to communicate to general public great science the agencies enable!

I understand reviewers concerns. A large number of young scientists worked hard to write and submit NSF CAREER proposals very recently. Their future livelihoods depend on the greater scientific community for qualified reviews and panelists for critical assessment. Do we simply abandon them?

Overview of the NSF Proposal and Award Process Understand the lifecycle of a proposal to the NSF, from preparation and submission to review and award processing.

I can't speak with certainty to future possible reorganization(s), but currently (as in past), panel and individual reviewers are advisory. POs make recommendations using this input, but these must be concurred by director(s), and final decisions and awards made by DGA

Amid Fear of Retaliation, N.S.F. Workers Sign Letter of Dissent

To add one more point, the recent (negative) changes are outside NSF program officers control, and arrive with no advance notice. There are limited or no way to communicate messages upward. Hence, carefully worded letters aimed to protect jobs are crafted. www.nytimes.com/2025/07/22/s...

Letters to the editor on AI, Chemical Safety Board, and more Chemical & Engineering News (C&EN): Keeping you up to date with the chemistry news that matters most. Published by the American Chemical Society.

Declining to serve on an NSF panel does not make a statement, it makes the program officers job harder. I wrote a letter to editor on this specific topic. Another potential outcome of collective declines is that helps justify the use of AI to replace human reviews, IMHO.

Improving Oversight of Federal Grantmaking By the authority vested in me as President by the Constitution and the laws of the United States of America, and to improve the process of Federal

BIG: A new executive order changes fundamentally how the U.S. awards research grants, giving oversight to political appointees in coordination with OMB.

All new grant opportunities are paused until these appointees are in place.

Had a great visit from my former postdoc @rjgilliard.bsky.social this week! Good to introduce him to some other program officers as well.

With the upcoming heat wave, I’ll need some of that cyclopentane flavored ice cream I saw the other day. #chemsky

Outstanding and well deserved!

Many of you may have known Greg Hillhouse, who passed away in 2014. A memorial fellowship has been set up in his honor at the U. of Chicago chemistry department. Here is the link if you are interested in finding out more.

Infographic on suppressing wildfires with chemistry. The graphic looks at Phos-chek, a fire retardant which contains ammonium phosphates or sulfates as the active ingredient. The red colour comes from iron(III) oxide. While Phos-Chek only causes mild skin and eye irritation for humans, it’s hazardous to aquatic organisms. When applied in front of wildfires, Phos-Chek forms phosphate esters which form a protective char that slows wildfires’ spread.

As wildfires rage in LA, this graphic in @cenmag.bsky.social looks at one way chemistry can be used to tackle them: cen.acs.org/environment/...
