I've written a review on what I think is an extremely exciting direction in cryo-EM:

It's been a privilege to be involved with this. #FRET approaches have so many potential applications for linking in vitro studies with in cell behaviours, but lacked a consistent benchmarking molecule that works across systems: not any more! #IDRs #smFRET #singlemolecule

Q-score as a reliability measure for atomic coordinate models

Q-score as a reliability measure for atomic coordinate models

Q-scores are calculated for atomic models derived from 3D electron microscopy maps, measure how well the model fits the map and reflect the quality of the map itself.

What happens when you combine all that is known about a large protein with almost 2000 residues with Alphafold2, new experiments, and in-depth structural bioinformatics? www.life-science-alliance.org/content/9/4/...

(BioProcess) Exploring fungal polymerases for chemoenzymatic oligonucleotide synthesis at University of York on FindAPhD.com PhD Project - (BioProcess) Exploring fungal polymerases for chemoenzymatic oligonucleotide synthesis at University of York, listed on FindAPhD.com

Are you looking for an interdisciplinary PhD? I have a 4 year PhD opportunity in my group to work on devising enzymatic route to oligonucleotide synthesis - combines protein engineering, directed evolution & X-ray crystallography at York with nucleotide chemistry at MIB, University of Manchester.

Having made the transition from primarily X-ray crystallography to cryoEM, this resource would have been invaluable.

It was great to play a part in this study, using all of the work on alphaproteobacterial GTAs to help inform and identify key tell-tale patterns of GTAs in the human gut microbiome. I'm sure there will be many great followup studies on these fascinating particles.

These are the life-blood of science. All that lab knowledge lost, careers ended. All the investment in their training to this point lost to academic research. That's the human cost of UKRI's "review period to develop implementation"

I know what they're getting at with the "could put jobs at risk" but can we focus on the immediate impact? Each suspended round at MRC and BBSRC means about 80 fewer postdoc jobs and the retrospective cuts at MRC add another 30 or so

We need to be shouting about the effects of this on junior researchers from the roofs, writing to our MPs. We are risking a "missing generation" of researchers.

MRC instructs grant review boards to slash funding rates - Research Professional News Boards asked to recommend just three applications for funding, as BBSRC also suspends calls

Would have been good to have added an apology for the lack of comms so far this year, particularly for those that submitted grants to UKRI applicant-led funding streams in Sept 2025, as these are highly unlikely to be funded (www.researchprofessionalnews.com/rr-news-uk-r...)

Open letter from Ian Chapman to research and innovation community UKRI Chief Executive outlines changes to UKRI investment approach, addressing concerns about research funding and the financial position of STFC.

I am sorry. We all knew the three buckets were coming. We are all prepared for a shift in priority. But this message does nothing for all the UK scientists dependent on project grant funding. It doesn’t actually give any information

Finally comms from UKRI - on a Sunday evening. No mention of the hundreds of ECRs who will see their careers ended by these decisions and notably no explanation for MRC retrospectively applying cuts and wasting all the work that went into writing, reviewing and scoring applications - £millions

Dr Sir Ian
If this statement is supposed to reassure that everything is under control, you are sadly very wrong.
Strategic change needs managing to take the community with you, what’s happening now with MRC, BBSRC, STFC etc looks like panic & smells of desperation.
Do better

At a time when the UK should be capitalising on its global reputation as a great place to do science, this is an enormous own goal. I am so sorry for all those who jobs are going to be impacted.

Leaks everywhere and finally we get an official statement, one that somehow manages to say a lot while; No timelines. No clarity. No acknowledgement of impact on ECRs whose careers depend UKRI funding.

“Later this year” isn’t a plan. And the sector deserves better than reassurance without detail.

Startling that this is being broadcast in the absence of any public communications by @ukri.org

The academic community has a right to expect to be told first hand what is happening with response mode funding and what the immediate future looks like
